This review summarises information that is relevant to concerns that have recently been expressed about stunning and slaughter. It is known that captive bolt stunning can result in brain material passing to the lungs via the jugular veins. If future studies show that BSE prions pass beyond the lungs to the edible carcass, there will be a move away from captive bolt stunning in large cattle towa...

this study was conducted to evaluate the effects of different proportions of lemon bee brush essential oil on growth performance, carcass composition, and hematology and biochemical parameters of common carp (cyprinus carpio). common carp with an average weight of 8 ± 0.2 g were fed for one month with a diet supplemented with lemon beebrush essential oil (0.15 and 0.3 ml) and with normal diet a...

An experiment was conducted to evaluate the influence of replacing fish meal with maggot meal on the performance, carcass characteristic, haematological and serum biochemical indices of growing rabbits. Sixty rabbits of mixed breed, aged 6 – 8 weeks were randomly taken for the dietary treatments in a completely randomized design with twelve rabbits per treatment were replicated three times with...

The most common commercial slaughter method for portion-sized rainbow trout is asphyxiation in ice slurry. This method is however widely believed to expose the fish to unnecessary pain and suffering. The industry is consequently seeking an alternative method, which offers improved welfare of the fish at slaughter. Electric stunning of fish in water is identified as a suitable method. Parameters...

Diploid and triploid rainbow trout weighing approximately 3g were either fed for five weeks, or feed deprived for one week, followed by refeeding. During feed deprivation gastrointestinal somatic index decreased in diploids, but not triploids, and during refeeding, carcass growth rate recovered more quickly in triploids. Although not affected by ploidy, liver ghr2 and igfbp2b expression increas...

Two hunared day old broiler chicks were alloted to five treatment groups evaluate the effect of whole soyabean and fish meal supplementation on productivity experimental birds. Feed consump­tion weight gains similar diets 1 -and 3, while feed efficiency protein ratio better (P<0.05) cooked diet 3 as compared groundnut cake based (control) ration. Fish also unproved performance. The raw gave ...

skeletal deformities are a common problem in fish hatcheries and commercial farms that affect growth, development and survival as well as the market value of the final product. among the nutritional components, phosphorus (p) and calcium (ca) are of special interest as they are directly involved in the development and maintenance of the skeletal system. hence, the present study was carried out ...

background: vitamins are considered an essential part in diet of aquatic animals. objectives: this study was carried out to assay the effect of different levels of vitamin e on growth performance, carcass compositions and blood parameters of common carp fingerlings (cyprinus carpio). methods: total number of 96 common carp fingerlings weighing 15.49 ± 3.64 g were randomly distributed into 12 fi...
