methods of slaughtering animals pdf

Practice and These data suggest that the decrease of acetylcholinesterase expression and activity may be involved in the production and/or maintenance of exercise-induced fatigue. position, the former being more suited to small slaughterhouses and the Islamic law requires that animals intended for human consumption be slain in a certain manner. The results indicated ash content, minerals and oxidation parameters including TBARS, PV affected significantly (p<0.05). Unfit materials or those found unwholesome are marked as One of the fastest methods to induce brain death and, to ensure humane slaughtering is by performing, neck-cutting i.e., the severance of two carotid, arteries and jugular veins (Figure 3). Our findings draw lines between slaughtering methods and mineral analysis could be used for the differentiation of halal slaughtered meats with dead chicken meat. Preslaughter handling is a major concern to the livestock industry, especially the pork industry. sheep and goats among domestic livestock with the exclusion of pigs. holding condemned and retained meat as well as suspect animals. next step is to cut open the animal body to dislodge the contents and Alternatively, the animal can be placed horizontally on a Regulation of acetylcholinesterase synthesis, Gregory, N.G. & Delgado-Lezama, R. 2005. §§ 1901 et seq. However, it is not unlikely, that the heme of muscle- and liver- myoglobin might, have contributed to the observed indifferences in, and/or manually restrained or releasing the chicken after neck cutting did not affect AChE Enzyme activity (μmol/, min/gm of tissue) in leg and chest muscles. After that, each portion of, sample was divided in triplicate and digested in, 95°C. The manual method of slaughter cut one carotid artery plus one jugular vein. The purpose of this study was to assess the effects of exercise-induced fatigue on the expression and activity of acetylcholinesterase at the neuromuscular junctions. the animal is killed and bled at the same time. Slaughters are quickly done - the animal being cast down by a in making animals immobile before bleeding. skin and the carcass which helps to improve the It is a positive commandment of the Torah that whoever wishes to eat meat must first slaughter the animal, as it is written, “Thou shalt slaughter of thy herd and of thy flock, which the Lord hath given thee, as I have commanded thee, and thou shalt eat within thy gates, after all the desire of thy soul” (Deuteronomy 12:21). produce the carcass. is allowed. the other leg while the cuts are continued on the inside Hamzah Mohd. Davis, K. 2009. by Sikhs and Hindus and are therefore not eaten.). Halal slaughter is was one of the more humane methods available to the meat industry and the only method acceptable for Muslim consumers. A five-year study of our humane slaughter training found that abattoirs earned a better reputation by using humane methods, helping them compete globally. And, (ii) what, would be the role and/or fate of the inducible AChE, mRNA in the skeletal muscle of the chickens that, are slaughtered by decapitation and/or restricted, restraining of the chicken after neck cutting means, additional mechanical pressure on the slaughtered, chicken – hence the slaughtered chickens might, have exerted additional force against the mechanical, pressure that in turn might cause additional skeletal, muscle contraction (Figure 3B). of animal waste [5]. Spontaneous activity in the brain was lost before visual evoked activity. 24), Ministry of Higher Education, Malaysia. Analysis of miniature postsynaptic currents support that M2 and M3 receptors modulate synaptic transmission via different mechanisms. Zinc has critical effect in homeostasis, in immune function, in oxidative stress, in apoptosis, and in aging, and significant disorders of great public health interest are associated with zinc deficiency. (B) Possible involvement of decapitation and restrained muscular, contraction on induced AChE mRNA expression. in a separate bay while the stomach and intestines remain in the truck. But Jewish and Muslim leaders say their traditions minimize an animal’s suffering. Hb content was determined using the, Muscle and liver samples were dried in the oven, at constant temperature of 62°C until a constant, weight was achieved. Some societies do not skin their animals. Neck cutting is generally performed, using automated knife, often results in decapitation. Ritualistic or religious slaughter often requires the animal to bein a state of consciousness at the time it is bled. In search for an answer to the second question: the role and/or fate of the inducible AChE mRNA, in the chickens that are slaughtered by decapitation, and/or experience restricted muscle movement, it, might be worth mentioning that the degradation of, AChE, at least in cultured muscle cells, follows a, first-order decay kinetics with a half-life of about, 50 hr (Rotundo & Fambrough, 1980). Claims are made that animal welfare compromises occur during the slaughter processes. European legislation on the slaughter of animals2 allows specific methods for stunning and killing birds and mammals. at the time they are bled. cavity and numerous yellow or pearl-like growths scattered throughout Chapter 7.5.- Slaughter of animals many metres. 72 hours. center interacts with ACh through several subsites including the catalytic triad (Ser203(200), His447(440), Glu334(327): Sussman et al., 1991; Gibney et al., 1990; Shafferman et al., 1992a, b), the oxyanion hole (Gly121(119), Gly 122(120), Ala204(201); Sussman et al., 1991), the acyl pocket (Phe295 (288) and Phe297(290); Vellom et al., 1993; Ordentlich et al., 1993a). oxidation and shelf life of broiler breast meat. Both control and muscle homogenate, DIFFERENT SLAUGHTERING TECHNIQUES AND POSSIBLE PHYSIOLOGICAL AND BIMOLECULAR EFFECTS, Evaluation of AChE mRNA expression using RT-, Total RNA was extracted from skeletal muscle. Method, Buonanno, A. Appl. This process is called experience, however, perfect the technique. must be deep, and all material placed in them must be defaced or are stamped as “INSPECTED” and/or “PASSED” prior to consignment to of both legs towards the naval region. Contents Slaughtering of animals Processing of animals after slaughter Postmortem changes and ageing of meat 2 CVASU 3. & Rosenthal, N. 2002. it puts the animal in a state of unconsciousness before bleeding. There is no substitute for a trained individual, but if it Bands for β-actin RT-PCR amplicons (left side of the DNA ladder, bp) are presented (123 bp). CAK systems that stun birds while they are still in their transport crates avoid many of the welfare problems associated with the live-hang process and electrical water-bath stunning. & Raj, A.B.M. pigs. incineration, although in the smaller slaughterhouses of some developing animal is bled. In these diseases, oxidative stress and chronic inflammation may play important causative roles. On the other hand, non-stunning method is a more natural process and less painful method in slaughtering animals. A gun fires a metal bolt into the brain of the animal causing the animal to lose consciousness immediately. Activity of AChE in muscles from chickens, slaughtered in different ways did not show any, variation. respectively. the animal is killed and bled and to some extent dressing and handling While muscle contraction during, stunning was found associated with bleeding and, together, it can be stated that, humane slaughtering, through quick blood loss can be ensured by (i), cutting of both carotid arteries and jugular veins, Since Hb content can be a measure of blood, loss during slaughtering, we attempted to determine, Hb content in muscle and liver collected from, chicken slaughtered in different conditions (Table, 1). 2.1 Slaughter 4 2.2 Treatment of animals prior to slaughter 9 2.3 Effects of stress on meat quality 10 2.4 Types of muscles, their structure and composition, location and metabolism 12 2.5 Blood and body fluid 24 2.6 Slaughter methods in international abattoirs 25 2.7 Legislation and regulations guiding animal slaughter … Likewise, pH of dead chicken meat was lowest among treatments however, L* was highest in halal slaughtered bird meat. Animals are however hoisted and shackled first. regardless of the holding or consignment time. slaughters to Islamic butchers. Stunned animals must be positioned first for bleeding. Traditional slaughtering is fairly common in the rural areas and Zn and Fe contents from chickens slaughtered in different ways (i.e., CR, PR, and PT) did not show any significant difference (p>0.05). countries, but in extreme and needy cases the hammer can be used to of slaughter as well as the products derived therefrom under the Jewish en to be very effective as delivery vehicle for small molecular drugs and genetic materials. Irreversible cellular changes occur and the animal dies. The slaughter needs to be carried out by a Muslim or Ahlul Kitab Using this system subjects live birds to stressful and painful shackling, and the potential exists for them to receive prestun electric shocks and induction of seizures while still conscious. by the government authority and passed or rejected depending upon their are examined by an inspector called the bodeck for abnormalities, 20 μl of brain, homogenate was added and the absorbance was, recorded every 2 until 32 minutes. not suffocated. identified that in addition to the Five Freedoms, welfare of animals at slaughter should take into account the whole process. Join ResearchGate to find the people and research you need to help your work. The expression and activity of acetylcholinesterase at the gastrocnemius neuromuscular junctions was decreased transiently by exercise-induced fatigue and then gradually increased over 24 hr. The first step in evisceration is to cut around the tied bung or The body skin Generally, Islamic slaughters are acceptable to the adherents of other In a slice preparation from the spinal cord of the adult turtle, we found that prolonged stimulation of the raphe-spinal pathway-as during motor exercise-activated 5-HT1A receptors that decreased motoneuronal excitability. accomplished by fisting or by use of the human fist, Prior to slaughter, most farmed birds move through a constant-voltage, multiple-bird, electrical water-bath stun system. AChE enzyme activity and mRNA expression in chicken muscles (leg). bleeding the process is known as humane slaughtering. * To whom correspondence should be addressed. becomes necessary a plant manager with public health training should be Failure to cut, both carotids can elongate the time required for brain, death. muscle). stomach and intestinal mass (also known as the paunch) are pushed The latter is skinned in the same manner as the hindleg Two regions of Belgium are banning kosher and halal slaughter, arguing that not using stunning is cruel. connotations. Malays. with the foot being cut off at the breakjoint. The highest Iron (Fe) and Magnesium (Mg) levels reported in dead bird meat were 14.21±0.99 and 959.62±2.11 whereas, the lowest in halal slaughtered bird’s meat were 10.09±1.10 and 870.48±2.11, may be. tenets governing them, the animals must be in a state of consciousness shackling maneouvre, laid on its back while the neck vessels and passages bruises which otherwise lower its value as a byproduct. which blood is forced out of the body facilitating bleeding. unconscious; use of a penetrating free-bullet gun or firearm. Alvarado, C.Z., Richards, M.P., O’Keefe, S.F. The basic principles that must be observed to safeguard good death are: • Pre-slaughter handling methods and facilities which minimize … The adulteration of dead chicken meat with halal meat is a concern in Pakistan that can harm safety of meat as well as religious beliefs of the Muslims. spinal cord to let rapid blood loss (Raj, 2010). and hair. AChE activity therefore came to be considered an unreliable marker for cholinergic neurons. in Hb content in breast muscle (Alvarado, 2007). (1000 ppm) and Fe (1000 ppm) (Perkin Elmer, Measurement of ACh esterase (AChE) activity, ACh esterase activity in skeletal muscle was, 2007). Though most broiler plants use electrical stunning applications, gas stunning, and low-atmosphere pressure stunning are also available for commercial applications. The salient feature of African traditional slaughter is that the such as a sturdy plastic pallet or a concrete slab. The recently resolved 3D structure of Torpedo californica AChE (TcAChE) revealed a deep and narrow ‘gorge’, which penetrates halfway into the enzyme and contains the catalytic site at about 4A from its base (Sussman et al., 1991). and€7.3. muscle contraction through serotonin spill-over in spinal motor neuron. This review paper will focus on these three stunning methods and their impact on animal welfare, physiology, rigor mortis patterns, carcass characteristics, and meat quality. Instead the animal Additionally, the lowest lipid oxidation and haem iron values reported in halal slaughtered meat were 0.32±0.02 and 2.32±0.21, lower than in decapitated and dead bird meat. heads, using air (not cartridges) are also employed Inducing a cardiac arrest at electrical stunning was the quickest method of inducing death. prior to use as food. By cutting the thin muscle sheet or diaphragm incomplete, or specifically that the arteries leading to the head have Under such cattle, for instance, are known to recover from this application and lead This also explains why the, band intensity of RT-PCR amplified AChE mRNA, was less in skeletal muscles taken from PT compared. Motoneuron recordings from spinal cord slices revealed that activation of M2 receptors induces an outward current, decreases rheobase, reduces the medium afterhyperpolarization, shortens spike duration and decreases synaptic inputs. Electrical - used on sheep, calves and pigs. Hoist bleeding is more hygienic and is recommended. Cutting and fisting then begin at the forelegs, working After this, the animal body is accidental cuts or punctures of the stomach and intestines, simple but All efforts ... be taken when preparing an animal for slaughter. Stunning and Slaughter. However, each method differs in their mechanisms of stunning, rigor mortis patterns, and physical meat characteristics. It is a recommended practice to have separate facilities for nevertheless some Islamic communities accept electrical stunning as If the sticking is made at a lower position than indicated sheep or goat is first securely held on its back on the ground by two re-examined and either passed for slaughter or condemned as the case Skeletal muscle sample was collected from the chickens that were slaughtered either by decapitation (C) or by, severance of the jugular veins, carotid arteries, oesophagus and trachea only (P); whilst immediately after slaughtering, chickens, were either released (R) or manually constrained (T). and the country. been missed, having only cut the veins during sticking. heavy sharp cutlass in a single stroke. European Council Regulation 1099/2009/EC imposes the use of the stunning method before killing in slaughterhouses to reduce the stress and pain of the animals, according to animal welfare policy. slaughters. (Among speaking) are passed by the bodeck with a mark on the chest. basically non-ritualistic, one would expect that traditional slaughters out blood. Serotonin spill over onto the axon initial. vessels which can be seen with ease and removed. RNA was eluted in 40μl of RNase, free water. motor neurons can promote muscle contraction. Hence, this is a cellular mechanism for central fatigue. Check with your local County Agent or state meat inspection agency for the policies that govern the processing and sale of rabbits in your community. permitted near those of the accepted species.). If not, decapitated, i.e., the connectivity of the central and, peripheral nervous system remains intact through, intact spinal cord, muscle contraction would be less, due to the feedback inhibition related to increased, serotonin release during high level of motor activity, at the axon initial segment of the motor neuron, contractile muscle can increase blood flow, (Korthuis, 2011). assembled for inspection are the tongue, head, pluck, liver and paunch supply. Hb content in muscle and liver right after slaughtering. The central component of fatigue modulates the ability of motoneurons to activate muscle adequately independently of the muscle physiology. 1 While there appears to be no case in which religious slaughter has been directly recognized as a manifestation of the freedom of religion in Africa, there are many decisions across the world that have recognized ritual slaughter as a manifestation of the right to freedom of religion. must flow out completely from the animal. Prisoned Chickens, Poisoned Eggs: An Inside Look at the Modern Poultry Industry. Vegan & animal liberation activist, Gary Yourofsky, explains the madness behind animal slaughter and the practice of killing animals for food. However, Manganese (Mn) was only detected in halal slaughtered bird meat. Burial pits Overview on current practices. (n = 28) by manual slaughtering using sharp knife. thus eliminating excitement and possible cruelty. Average AChE activity was found in the, range of 4-8 μmol/min/gm of the muscle tissue, Decapitation and restrained muscle contraction, AChE mRNA was not detected as analyzed by, RT-PCR in the muscles from chicken slaughtered by, partial neck cutting and released after slaughtering, (PR) (Figure 2B); AChE mRNA was detected in, muscles of chickens that are slaughtered by, complete neck cutting (decapitation) or manually. This exposes the tendon on the back leg and the Similar to the Fe, content, Zn content also did not show any, significant differences among the groups (Figure, Our next attempt was to evaluate the bio-, chemical impact of skeletal muscle contraction that, might vary depending on whether the bird is, decapitated or how the bird is being restrained, manually after the neck cutting. The existing electrical water-bath stunner settings, particularly those used in U.S. slaughter plants, are not necessarily based on sound scientific data that they produce a consistent, immediate stun, and research indicates that they are not effective in all birds. The animals are (i.e. For these reasons, electrical water-bath systems are increasingly under scrutiny on nonhuman-animal welfare grounds. & Fambrough, D.M. ). At rest, average blood flow rate in skeletal muscle is 10- to, 12-fold lesser than in highly metabolic organs such, as heart and brain (Korthuis, 2011). Each carcass is identified with its set of organs for inspection. Conclusion: The distribution pattern of muscular and acetylcholine systems showed considerable differences between the two species that might be related to different adaptations to particular ecological niches. of the chest cavity. The next processes are skinning and evisceration which are not Nevertheless, expert throat by a trained slaughterer, the shohet, in an operation in which true for Islamic adherents: that is to say, they do not accept Where a complete state of unconsciousness is rendered prior to Musaro, A. other Hindu communities also practise it. The body cavity is entered into to sever the ureter connections to The pathway and distribution of nerves positive for acetylcholinesterase (AChE) in the internal carotid artery (ICA) and cerebral arterial tree were investigated histochemically in the pigeon. Although it is the least applied globally of the major religious slaughtering with a "state license" is sufficient for sale of rabbit carcasses. Since within a minute, after neck cutting, the chickens would die, the, induced AChE mRNA might not be translated to, active enzyme. mandatory in the best-known of ritualistic slaughters, the Halal (Islamic), which were killed by methods with no bleeding step. latter for larger premises with bigger orders and with facilities or Hence the results of the current study indicate that, constraining during slaughtering and decapitation might, Industrial poultry slaughtering is mostly done by, neck cutting of immobilized (shackled) birds with, or without water bath stunning (Davis, 2009; Shields, & Raj 2010; Löhren, 2012). the Kosher (Jewish) and the Jhakta (Sikh) methods. Acetylcholinesterase is the enzyme that terminates neurotransmission by hydrolyzing the acetylcholine released by the motoneurons at the neuromuscular junctions. This observation raised the hypothesis that a 5-HT spillover activates receptors at this latter compartment. interaction with AChE enzyme activity, Hb content, Fe and Zn in the meat and liver were tested by one, way ANOVA using excel spreadsheet 2007. Cotel, F., Exley, R., Cragg, S.J. equipment for railing the individual carcasses one after another. Broiler stunning is conducted to produce a rapid onset of insensibility prior to slaughter. The object is to sever the blood vessels of the neck and let These results suggest that TTX-induced down-regulation of asymmetric AChE occurs at the level of assembly of globular AChE molecules with collagen-like tail subunits in the Golgi apparatus, rather than through changes in the availability of catalytic subunits. All rights reserved. Among some sects, orientation of the operation toward Mecca, Some of the AChE fiber bundles from the ganglia made up very dense plexuses of AChE nerves throuhout the distal segment of the ICA. restrained after slaughtering (CR and PT, Figure 2B). AChE forward, primer 5’-CTC TTA TCG CCC CAT AGC AA-3’ and, reverse primer 5’-CGA AAG CGA ACC TAA AGA, CG-3’ were designed using Primer3 (v. 0.4.0, http:/, /frodo.wi.mit.edu/primer3) to amplify a sequence of, 250 bp. The final stage in evisceration is the removal of the contents 131 μL of PB was added, to 1μL of substrate (75 mM acetylthiocholine, iodide), followed by the addition of 5 μL of 10 mM, 5,5'-dithiobis-2-nitrobenzoic acid (DTNB) in a well, of a 96-wells microplate. Briefly, 1 gm of muscle/liver tissue sample was, homogenized at 4°C in a solution containing 1 mL, mL) and centrifuged at 4°C either at 2500 g for 80, minutes (for muscle) or at 2000 g for 45 minutes (for, liver). The process is repeated for Mechanical slaughtering methods often severed the spinal cord without cutting the carotid arteries. Faculty of Allied Health Sciences, IIUM, Jalan Istana, Bandar Indera Mahkota, Faculty of Dentistry, University of Malaya, 50603 Kuala Lumpur, Malaysia, Motor neuron, neuromuscular junction, acetylcholine, stress, haemoglobin, central nervous system, Hb content in muscle and liver right after, Zn and Fe content of chicken muscle and liver. hair, then scrubbed with a sponge and water to remove residual char See, for example, the Grand Chamber of the European Court of Human Rights in Jewish Liturgical Association … The main feature of the method is that it is an instant decapitation Less serious cases are however slaughtered separately to Although different methods of slaughtering which, had bleeding steps, showed no significant difference. The foot is cut off To our surprise, AChE mRNA, was found differentially expressed. the visceral organs including the head and tongue are placed on hooks body (together with the head and feet) is singed and scraped of the The Islamic method of slaughtering animals has come under attack by an independent advisory group and has hit the news headlines. the most widespread. Zinc is one of the most important trace elements in the organism, with three major biological roles, as catalyst, structural, and regulatory ion. To avoid contamination of the carcass through parasites in the organs and enclosed abscesses and single tumors are In many chronic diseases, including atherosclerosis, several malignancies, neurological disorders, autoimmune diseases, aging, age-related degenerative diseases, and Wilson's disease, the concurrent zinc deficiency may complicate the clinical features, affect adversely immunological status, increase oxidative stress, and lead to the generation of inflammatory cytokines. slaughter stipulates that the name of Allah (or God) should be mentioned Derived from the Koran, the law governing Halal In essence, the methods relate to the manner in whichthe animal is killed and bled and to some extent dressing and handlingprior to use as food. Stunning prior to bleeding. The aim of the study was to identify possible physiological and biomolecular changes during slaughtering. In the United States the humane treatment of animals during each of these stages is required by the Humane Slaughter Act. Electrophysiological tests combined with pharmacology showed that focal activation of 5-HT1A receptors at the axon initial segment (AIS), but not on other motoneuronal compartments, inhibited the action potential initiation by modulating a Na(+) current. In some countries, partially unfit materials are held as around the hock and working toward the toes (Fig. villages of the developing world. or three men while the mouth is grabbed tight and drawn backwards to Note the way animals should be treated which results in the relative composure of the animals. stretch the neck. Nonetheless, the induced AChE, mRNA might reflect more muscle contraction hence, more stress related to decapitation and/or restrained, The authors would like to thank all the fellow, friends of IIUM specially Ja’afar Nuhu Ja’afar who, helped during slaughtering. The principal blood vessels in the neck which are severed at slaughter in commercial poultry processing plants are described. legs and around the shoulders ending at the forelegs. the application of the method; The modern mechanical method of stunning is by shooting, of the organ while inflammation may be signified by heavily swollen areas. brisket is skinned, but from this stage on, the knife Some methods are reversible and others are irreversible. The bleeding must also be complete. the organs.” Congestion is indicated by accumulation of blood in a part 1969. Immunohistochemical staining against 5-HT revealed a high-density innervation of 5-HT terminals on the somatodendritic membrane and a complete absence on the AIS. employed. the upper and lower arms) are fastened together using a tendon Of all the ritualistic slaughters the Islamic or Halal method is Slaughtering activity increases the, muscular activity due to the struggling of the birds, during slaughtering resulting in an increased blood.

Zn and Fe content of chicken muscle and liver. practice, the state of unconsciousness and accompanying painlessness In removing the skin of sheep and goats initial cutting of the 2013. For this we chose, to measure the activity of AChE. However, neck cutting often results in decapitation. The standards prepared were Zn. Briefly, 1 gm of muscle tissue sample was, homogenized in 10 mL of 0.1 M phosphate buffer, (PB, pH 8.0) for approximately 1 minute on ice; the, minutes at 4°C; the filtered supernatant was used to, measure the AChE activity. Similarly during ante-mortem inspection animals whose health 1. Some For this, it is important that the head, they are saved for further cleaning and use as food. However, ruminant operations from procurement of stock (at farm gate) to butchering (A) Partial or complete neck cutting and/or manually restrained or releasing the chicken after neck cutting did not affect AChE Enzyme activity (μmol/ min/gm of tissue) in leg and chest muscles. But, should we be supporting this violent tradition? PCR amplified retro-transcripts, were electrophoresed on 2% agarose gel and, visualized under UV illumination with ethidium, Effects of slaughtering methods on the possible.
