Featherless and feathered broilers under control versus hot conditions. 1. Breast meat yield and quality.
The improved genetic potential of contemporary commercial broilers cannot be fully expressed under hot conditions that depress growth rate, decrease breast meat yield, and reduce meat quality. The negative heat effects are attributed to the insulating feather coverage, which, under high ambient temperatures (AT), hinders dissipation of the excessive internally produced heat. Accordingly, feathe...
متن کاملFeatherless and feathered broilers under control versus hot conditions. 2. Breast muscle development and growth in pre- and posthatch periods.
Breast meat yield (% of BW) of featherless broilers (sc/sc) is higher than that of their feathered sibs (+/sc) and contemporary broilers (+/+) under hot temperature (32°C) conditions. This study tested the hypothesis that the advantage to the featherless broiler condition with respect to breast meat yield and quality is due to differences in muscle development during pre- and posthatch periods....
متن کاملGrowth Traits, Breast Meat Yield and Quality of Broiler Genotypes under Hot Conditions
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...

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
