Abstract
Thai red junglefowl (Gallus gallus gallus) is found in the forest of the Northeastern and Eastern regions of Thailand and nearby neighborhood countries. Biology information on the Thai red junglefowl is barely entry. The study's objectives were to investigate the hen’s reproductive performance, phenotypic characteristics, and growth performance of young male and female Thai red junglefowl. The aged 1 old year breeder; 1: 4 of males on females are raised in each cag, 3 cags in total. Twelve of each newborn male and female chicks were randomized separately to each pair per cag. They were raised under natural circumstances, given light 14 hours/day, providing feed and water ad libitum. It found that the hen’s reproductive performance, the average number of eggs laying is 82.90±12.94 eggs/hen/year, and the fertility and hatchability rates are 70.22 and 40.23% of total eggs incubated. The increased amount of rainfall does not correlate with the percentage of egg production; however, it correlates with the percentage of fertilized eggs. Anyhow, the increased amount of rainfall decreased the hatchability rate. The phenotypic characteristic at birth cannot be gender distinguished by feather color. The difference between males' and females' feather colors appeared after 2 months. The chicks become mature chickens with faster development than raising in the natural circumstance after 12 months. Both males and females have white earrings, a light-yellow new feather, and a black streak. The shape is slender, like a banana flower. Males are reddish in color with a slightly blackish tinge, slender tail feathers, and the base of the tail has fluffy white fur. Females have slightly reddish gray feathers and short tail feathers. The growth performance from birth to 1 month is nonsignificant different (P>0.05). From 1 to 7 months is greater in male phenotypic characteristics development than in females (P<0.01).
