A total of 150 day old female chickens (Ross 308) were randomly allocated to 2 groups with 5 replicate and 15 chicks in each replicate to determine the effects of cold induced ascites on performance, antioxidant status, blood enzyme activities and bone metabolism. The two experimental treatments were: 1) chicks that reared under normal temperature (NT) and 2) chicks that reared under cold tempe...

the present study performed to examine canola meal on morphology of thyroid gland in broiler chicks. in this experiment 300 l-day-old unsexed ross broiler chicks assigned into 5 groups. the chicks were fed by five level of canola meal (0, 5, 10, 15 and 20%). after 42 days feeding four chicks from each pen killed and their thyroid glands removed and immediately were immersed in formaldehyde, bef...

The Effect of Adding Different Levels Valine in Low Protein Diets on Performance, Blood Parameters and Tibial Bone Properties Ross-308 Broiler Chickens from 8-21 Days

This study was conducted to determine the effects of sumac, yeast, and onion supplementation broiler chicken feeds on performance. Four hundred fifty, one-day-old Ross 308 chicks were obtained from Yagoo Group Hatchery in Sulaymaniyah Province randomly distributed into three treatment groups (150 for each group) with six replicates (each 25 chicks). Chicks raised floor cages (210 × 200 100 cm)....

This study was conducted in order to evaluate effect of organic acids on broiler performance. Totally 180 chickens of Ross 308 hybrid were divided to three groups. Experimental group no. 1 (n=60) received acetic acid in drinking water with concentration 0.25% from day 1 to day 42. Experimental group no. 2 (n=60) received citric acid in drinking water with concentration 0.25% from day 1 to day 4...

The study aimed to compare meat traits from different ages and origin chickens fed with extruded soybean (ES) instead of meal (SBM). 150 male Ross 308 (R) Cobb 500 (C) were use...

The aim of this study was to evaluate the potential of two probiotic preparations, containing live lactic acid bacteria (Lactococcus lactis CECT 539 and Lactobacillus casei CECT 4043) and their products of fermentation (organic acids and bacteriocins), as a replacement for antibiotics in stimulating health and growth of broiler chickens. The effects of the supplementation of both preparations (...

The objectives were to determine the effects of insemination with sexed semen at spontaneous and induced estrus, fixed-time insemination at synchronized estrus, the deposition site, estrous intensity, housing, age, body weight, and bull on the pregnancy rate in Holstein heifers, and to compare the quality traits of sexed sperm with those of unsexed semen. The study was conducted on 3206 heifers...
