| ABSTRACT The study was planned to evaluate the effect of different naked-neck (NN) chicken genotypes and breeder ages on the growth performance of their progenies. A total of 126 chicks, from two breeder ages and three NN varieties, were reared up to 20 weeks of age. A randomized complete block design in factorial arrangement, with six treatments of seven replicates of two females and one male each, was applied. Treatments consisted of three NN varieties (light brown, black, and dark brown) and two breeder age groups (45 and 55 weeks old). Growth performance (body weight gain, feed intake and feed conversion ratio) were evaluated. Higher feed intake was observed in both the male and female progenies of 55-week-old compared with 45-week-old breeders. Light... |

| ABSTRACT The aim of the present study was to evaluate the effect of different anti-stressors on growth performance, carcass traits, bloodchemistry and meat quality attributes of broiler Japanese quail. For this purpose, a total of 1,875 quail chicks were procured and arranged according to completely randomized design, birds were divided into 5 treatment groups having 5 replicates of 75 birds each. The treatments consisted of four anti-stressors i.e., synthetic anti-stressors (Vitamin C and Betaine) and natural anti-stressors (Turmeric and Chia Seed) along with a control group. Bird’s diets were supplemented with vitamin C, betaine, turmeric and chia seed @ 600 mg/kg, 700 mg /kg, 300 mg/kg and 7,000 mg/kg, respectively. After four weeks, 10 birds per... |
