One hundred seventy-seven pigs were used to determine the interaction effects of fasting and length of transport prior to harvest on pork muscle quality. The study design was a 2 x 2 x 3 factorial, which involved two genetic sources, fasting (F) or no fasting (N) of pigs 48-h prior to harvest, and three transport times (0.5, 2.5, or 8.0 h) on a semitrailer to the packing plant. Genetic source w...

An experiment was conducted to determine the effects of betaine, pen space, and preslaughter handling method on growth, carcass traits, and pork quality of finishing barrows. For the growth trial, a 2 x 2 factorial arrangement of treatments was used: betaine (0 or 0.250%) and(or) pen space (m2/pig; adequate, 0.035 BW0.67 kg, or inadequate, 0.025 BW0.67 kg). Each treatment was replicated five ti...

The present study evaluated the carcass and meat quality traits of three groups Japanese quails. These {i.e. selected for 4-week body-weight group (WBS), egg number (EBS), random-bred control (RBC)}, were consecutive generations from a base population 1125 In total, 2700 four-week-old quails lines (225 birds per generation) slaughtered in total four (G0 to G3). effects selection on generations....

The present study was conducted to compare the supplementation of natural (D-α-tocopherol) and synthetic (DL-α-tocopherol acetate) vitamin E on the growth performance, meat quality, muscular antioxidant capacity and genes expression related to oxidative status of broilers. A total of 144 1 day-old Arbor Acres broiler chicks were randomly allocated into 3 groups with 6 replicates of 8 birds each...

The study evaluated the body weight during growth (BWG), body weight at slaughter (BWS), breast meat yield (BMYg), percent breast meat yield (BMY) and breast meat quality (colour and drip loss) of genetically featherless (scsc) broilers compared to their feathered sibs under hot conditions. Two hundred featherless chicks and 200 feathered sibs were reared under hot conditions in two rooms (aver...

Guanidino acetic acid (GAA) is naturally occurring in animal tissues playing a major role in the energy metabolism as a precursor of creatine. The objective of the study was to examine potential effects of GAA (CreAMINOTM) supplementation in purely vegetable diets compared to a positive control. Therefore a total of 780 male ROSS 308 broiler chickens were assigned to one of the following three ...
