[ 1 ] - بررسی تأثیرات تزریق مواد مغذی مختلف به کیسة زردة تخم‌مرغ‌های بارور، همراه با 36 ساعت گرسنگی پس از تفریخ، بر قابلیت جوجه‌کشی، عملکرد رشد و برخی فراسنجه‌های خونی جوجه‌های گوشتی
این تحقیق به منظور مطالعة اثر قابلیت تغذیة جنینی بر درصد جوجه درآوری، وزن اولیه بعد از هچ، عملکرد رشد، فراسنجه‌های خونی، سیستم ایمنی جوجه‌های گوشتی و مورفولوژی پرزهای روده انجام گرفت. در این مطالعه 240 تخم‌مرغ بارور سویة گوشتی راس- 308 (گلة مادر در سن 28 هفتگی)، در قالب طرح کاملاً تصادفی با پنج تیمار استفاده شدند. به هر تیمار سه تکرار و به هر تکرار 16 عدد تخم‌مرغ اختصاص داده شد. تیمارها عبارت ب...
[ 2 ] - Effects of a nanostructure of phytic acid absorber on the performance and protein digestibility in laying hens
A ten-week experiment was conducted to study the effect of a nanostructure of phytic acid absorber (NPAA) on the performance and protein digestibility in laying hens. A total of 100 Bovans laying hens were randomly assigned to 5 treatments, with 4 replicates, 5 hens each. The experiment was a completely randomized design with 5 levels of NPAA; including zero (T1, as a basal diet (BD)); T2 (BD+ ...
[ 3 ] - Effects of dietary supplementation of waste date’s vinegar on performance and improvement of digestive tract in broiler chicks
Two hundred 1-day-old commercial broilers (Ross 308) were used to determine the effects of diets supplementation with waste date’s vinegar (WDV) on the growth and performance of digestive tract over a 42-days growing period. Chicks were randomly allocated to one of five experimental diets supplementing as 0 (control), 1, 2, and 3% of WDV and 2% industrial vinegar (IV). Broilers and their feed c...
[ 4 ] - Effect of in ovo feeding of amino acids and dextrose solutions on hatchability, body weight, intestinal development and liver glycogen reserves in newborn chicks
Early development of the digestive tract is crucial for achieving maximal growth and development of chickens. This study examined the effects of in ovo (IO) feeding of 0.70 mL of dextrose (10.00% and 20.00%) or amino acids solutions into the yolk sac at day 14 of incubation on small intestine histomorphometry and histomorphology, intestinal development, hatchability, body weight, and l...
