Evaluation of Meat Byproduct – Sinews in Commercial Broiler Chicken Performance
A study was conducted for six weeks period to evaluate the effect of meat byproduct Sinews on commercial broiler performance in a total of 270 unsexed Vencobb chicks. The experimental feeds were prepared by including sinews at zero per cent (controlT1), 2 per cent (T2) and 4 per cent (T3) level in the feed. Addition of two per cent inclusion of Sinews in broiler chicken diet did not showed sign...
متن کاملSimulated preslaughter holding and isolation effects on stress responses and live weight shrinkage in meat goats.
The objective of this experiment was to determine the effects of preslaughter isolation and feed withdrawal duration on physiological responses and shrinkage in goats. A total of 84 Spanish does (36 mo of age, average weight 35 kg) were individually weighed and scored for excitability before two replicate (day) trials. The does were feed-deprived (FD) or fed (F) in holding pens (treatment, TRT)...
متن کاملEvaluation of potential disinfectants for preslaughter broiler crop decontamination.
The broiler crop has recently been implicated as a major source of Salmonella contamination at commercial processing. Furthermore, feed withdrawal has been positively correlated with increased Salmonella incidence in the crop, probably due to coprophagy. In the present study, a rapid screening assay was developed to evaluate several potential disinfectants in the presence of large quantities of...
متن کاملPreslaughter stress and muscle energy largely determine pork quality at two commercial processing plants.
The objective of the present experiment was to study physiological changes elicited in response to stress in the immediate preslaughter period and to link them to pork quality characteristics. Crossbred, halothane-free pigs (n = 192) were processed in eight groups (24 pigs per group) on various days at one of two commercial processing plants operating different stunning systems (electrical and ...
متن کاملModulatory Effect of Monochromatic Blue Light on Heat Stress Response in Commercial Broilers
In a novel approach, monochromatic blue light was used to investigate its modulatory effect on heat stress biomarkers in two commercial broiler strains (Ross 308 and Cobb 500). At 21 days old, birds were divided into four groups including one group housed in white light, a second group exposed to blue light, a 3rd group exposed to white light + heat stress, and a 4th group exposed to blue light...
