ABSTRACT
Noi chicken is one of the indigenous chicken breeds commonly raised in the Southern of Vietnam for the purpose of fighting games and food because its firm and crispy skin. Nowadays, there are not many surveys on the reproductive performance of this breed. The study aimed to evaluate some indicators of reproductive performance of Noi chicken over two generations (G0 and G1 generations). A total of 300 hens and 60 cocks at the 21 weeks old local Noi chickens were used in this experiment. They were randomly distributed into two treatment groups of 5 replicates (30 hens and 6 cocks) in a completely randomized design. Treatment 1 (G0 generation – beginning generation) included 150 hens and 30 cocks and treatment 2 (G1 generation – the offspring of G0 generation) with 150 hens and 30 cocks. Mating cocks and hens of G0 generation and collecting eggs to incubate for getting G1 generation. Some reproductive indicators and other performance characteristics were collected from 21-72 weeks old in each generation and the association between generations and productive traits was analyzed based on One way Analysis of Variance (ANOVA) with Minitab software version 16.0. The results showed that G1 generation had the highest average egg production rate (34.6%) and the lowest average FCR (4.60 g feed/g egg) (P<0.05). At 42 weeks old, the Noi hens reached peak egg production as follow 45.7% in G0 generation and 48.6% in G1 generation. The G1 generation had average feed intake for 10 eggs (3.29 kg) lower than G0 (3.53 kg). Egg production increased in G1 (125.8 eggs/hen) compared to G0 (117.5 eggs/hen), and also FCR improved in G1 (4.60 g feed/g egg) to compare with that of G0 (4.96 g feed/g egg). In concluded that the reproductive performance of Noi hens in G1 generation was better than that of G0 generations and these findings can be applied in the breeding of Noi chickens towards egg production.
