Morphology, Blood Chemistry and Behavioral Response of Crossbred Chickens Reared Under Alternative Production Systems
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 alte...

| description | 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 production systems. Comparing the behavior of chickens, higher feeding, jumping and dust bathing were observed in chickens reared in aviary systems than in other production systems while the maximum perching behavior was showed by the chickens reared in enriched cages. The highest glucose level was observed in RR genotypes when reared in aviary systems. Antibody titers against ND and IB were highest in chickens reared in aviary systems. In conclusion, RB and BR genotypes had better performance in terms of morphometrics and blood biochemistry when reared under enriched cages and aviary systems. |
