| ABSTRACT In the present study, the second generation of two genotypes RNN (Rhode Island Red × Naked Neck) and BNN (Black Australorp × Naked Neck) obtained by two self-crosses (RNN × RNN =RR and BNN × BNN= BB) and two reciprocal crosses (RNN × BNN = RB and BNN × RNN = BR) were evaluated in three alternative production systems (conventional cages, enriched cages, and aviary). In total 480 birds, comprising 240 pullets with 240 cockerels (60 pullets & 60 cockerels from each crossbred) were used during rearing phase (17-21 weeks). Higher body weight, shank circumference, body and drumstick length were noticed in RB and BR genotypes. Among different production systems, chickens reared in enriched cages showed higher body weight and body lengths than other... |

| ABSTRACT Objectives of the study were to investigate influence of artificial insemination (AI) in caged and floored flock in comparison to natural mating (NM) on broiler breeders’ welfare, productive performance and economic appraisal. To execute this experiment, a total of 1440 pullets of Ross-308 Parent Stock along with 168 males were picked from a commercial flock and divided into three groups i.e., AIC=AI in cages, AIF=AI on floor and third was NM=NM on floor. Each group carried 480 females (HH) while 168 males were divided into 41, 48 and 58 for AIC, AIF and NM, respectively. During both phases all procedures and studied parameters were the same except the sperm dose rates which were changed during post peak. According to the results, significantly... |

| ABSTRACT The present study evaluated the effect of housing system on the morphometrics, serum chemistry and antibody response of dual-purpose chicken genotypes. A total of 156 pullets and 39 cockerels were randomly picked from 18 treatment block groups (3 housing system × 3 genotypes × 2 sexes) according to Randomized Complete Block Design (RCBD). Three genotypes, purebred Naked Neck (NN) and two crossbred Rhode Island Red × Naked Neck (RIR × NN = RNN) and Black Australorp × Naked Neck (BAL × NN = BNN), were compared. Morphometric traits were recorded during rearing period, thereafter, serum chemistry and antibody response were evaluated in pullets. Intensive and semi-intensive chickens were heavier (males, p=0.0012; females, p<0.0001) on week 21. Body... |

| 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... |
