Investigation Into the Humaneness of Slaughter Methods for Guinea Pigs (Cavia porcelus) in the Andean Region
Contributor(s):: Limon, Georgina, Gonzales-Gustavson, Eloy A., Gibson, Troy J.
Guinea pigs (Cavia porcelus) are an important source of nonhuman animal protein in the Andean region of South America. Specific guidelines regarding the welfare of guinea pigs before and during slaughter have yet to be developed. This study critically assessed the humaneness of 4 different...
Cattle behaviours and stockperson actions related to impaired animal welfare at Swedish slaughter plants
Contributor(s):: Hultgren, Jan, Wiberg, Sofia, Berg, Charlotte, Cvek, Katarina, Lunner Kolstrup, Christina
At a slaughter plant, cattle are sometimes exposed to rough handling which may reduce animal welfare (AW). In an observational study at four Swedish commercial slaughter plants, AW-related behaviours of cattle and actions of abattoir stockpersons handling the same animals were recorded...
Application of the welfare quality protocol in pig slaughterhouses of five countries
Contributor(s):: Dalmau, A., Nande, A., Vieira-Pinto, M., Zamprogna, S., Martino, G. di, Ribas, J. C. R., Costa, M. P. da, Halinen-Elemo, K., Velarde, A.
The objective of the present study is to assess the variability of the measures used in the welfare quality (WQ) protocol for pigs among slaughterhouses in five different countries and to propose alarm and critical thresholds for the calculation of scores for future development of an animal...
Good Management Practice for Animal Handling and Stunning
Contributor(s):: Temple Grandin
These guidelines are a supplement to the 1991 Recommended Animal Handling Guideline for Meat Packers. The main emphasis of this guide is on the use of a welfare performance standards which can be objectively scored instead of specifying equipment design or practices. Scoring procedures for...
Assessment of aversion and unconsciousness during exposure to carbon dioxide at high concentration in lambs
Contributor(s):: Rodriguez, P., Dalmau, A., Manteca, X., Litvan, H., Jensen, E. W., Velarde, A.
The most widely used stunning method in sheep is electrical. However, in lambs, this method leads to rupture of the blood vessels, provoking ecchymoses. In pigs ( Sus scrofa), the use of CO 2-stunning systems has increased in popularity due to positive effects on meat quality and animal welfare...
Effects of catching and transportation versus pre-slaughter handling at the abattoir on the prevalence of wing fractures in broilers
Contributor(s):: Kittelsen, K. E., Granquist, E. G., Vasdal, G., Tolo, E., Moe, R. O.
Fractures occurring in conscious broiler chickens are painful and severely compromise animal welfare. The aim of this study was to investigate the effects of pre-slaughter handling procedures on the frequency of wing fractures. Wings were examined for fractures in 11,609 broilers, from 12...
Factors affecting penetrating captive bolt gun performance
Contributor(s):: Gibson, T. J., Mason, C. W., Spence, J. Y., Barker, H., Gregory, N. G.
Captive bolt stunning is used for rendering livestock insensible at slaughter. The mechanical factors relating to performance of 6 penetrating captive bolt gun (CBG) models were examined. The Matador Super Securit 3000 and the .25 Cash Euro Stunner had the highest kinetic energy values (443 J and...
Assessment of key parameters for gunshot used on cattle: a pilot study on shot placement and effects of diverse ammunition on isolated cattle heads
Contributor(s):: Schiffer, K. J., Retz, S. K., Richter, U., Algers, B., Hensel, O.
There have been many improvements regarding transport conditions, pre-slaughter handling, and captive-bolt stunning of cattle at commercial abattoirs, but many challenges still exist. Animals unaccustomed to human-animal contact, such as free-range beef cattle, may be especially difficult to...
Evaluation of microwave energy as a humane stunning technique based on electroencephalography (EEG) of anaesthetised cattle
Contributor(s):: Rault, J. L., Hemsworth, P. H., Cakebread, P. L., Mellor, D. J., Johnson, C. B.
Humane slaughter implies that an animal experiences minimal pain and distress before it is killed. Stunning is commonly used to induce insensibility but can lead to variable results or be considered unsatisfactory by some religious groups. Microwave energy can induce insensibility in rats, and...
A critical review of electrical water-bath stun systems for poultry slaughter and recent developments in alternative technologies
Contributor(s):: Shields, S. J., Raj, A. B. M.
Prior to slaughter, most farmed birds move through a constant-voltage, multiple-bird, electrical water-bath stun system. 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...
Handling and welfare of bovine livestock at local abattoirs in Bangladesh
Contributor(s):: Murshidul, Ahsan, Hasan, B., Algotsson, M., Sarenbo, S.
The World Organization for Animal Health (OIE) allows rope casting and the tying of legs for nonhuman animal slaughter without stunning. The handling and welfare of bovine livestock ( Bos indicus and Bubalus bubalis) were studied in 8 local abattoirs in 5 districts of Bangladesh. A total of 302...
Penetrating captive bolt stunning and exsanguination of cattle in abattoirs
Contributor(s):: Gregory, N., Shaw, F.
Abattoirs commonly use penetrating captive bolt pistols to stun cattle. Humane slaughter requires that an animal immediately becomes unconscious and does not regain consciousness. In this review we consider the concepts of concussion, unconsciousness, and return to consciousness. We conclude that...
Animal Welfare and Humane Slaughter
Contributor(s):: Temple Grandin, Gary C. Smith
Manteca (1998) says concern for animal welfare is a major consideration in meat production and is based upon the belief that animals can suffer. Welfare may be considered (Manteca, 1998) in terms of the subjective experiences of animals (measured using preference testing) or in terms of...
