Effects of In-ovo Injection of Different Nutrients on the Hatchability and growth Performance in Broilers
The aim of this study was to investigate the effects of in ovo injections of albumin, ami-no acid and dextrose into the amnion on the hatchability, growth performance and slaughter yield of Ross 308 broiler chicks. Fertile eggs (n=360) were assigned to 6 treatment groups (4 replicates of 15 eggs each) including: non-injected eggs (control), and eggs injected with 0.7 ml distilled water (sham), ...
متن کاملAscorbic Acid and Citric Flavonoids for Broilers Under Heat Stress: Effects on Performance and Meat Quality
The aim of this study was to evaluate the effects of increasing doses of ascorbic acid (AA) and citric flavonoids (quercetin and rutin) on the performance and meat quality characteristics of broilers submitted to cyclic heat stress. Four-hundred one-day-old female Ross 308 were housed in 40 battery cages a in temperature controlled room. Treatments consisted of 0, 250, 500, and 1000 g/ton on of...
متن کاملInfluence of In-ovo Arginine Feeding on Post-hatch Growth Performance and Economics of Broilers
A total of 420 fertile broiler eggs (Cobb) with uniform egg weight were collected and divided into three groups: non-injected control, injected control (0.5 ml of 0.9% normal saline) and arginine (0.5 ml of 0.5% arginine); and injected on 18 day (d) of incubation into amnion. On the 21 d, 108 chicks were randomly selected from each treatment totaling to 324 chicks. The hatchability, hatch weigh...

The Effects of Turmeric, Cinnamon, Ginger and Garlic Powder Nutrition on Antioxidant Enzymes’ Status and Hormones Involved in Energy Metabolism of Broilers during Heat Stress
This experiment was carried out to determine the effects of turmeric, cinnamon, ginger and garlic powder on mixed sex Cobb-500 broilers performance, serum antioxidant status, and serum thyroid hormones. Heat stresses were created by increasing ambient temperature to 32-34 ˚C from 12: a.m. to 16: p.m. during days 31-42 of the experiment. Blood serum samples were obtained from 6 broilers of each ...
