This research was conducted at Khao Soi Dow Wildlife Breeding Research Center, Chantaburi Province during October 2001 and December 2002. The objective was focused on factors related to the efficiency of captive breeding of Green Peafowl. Namely, pairing, proper ages of male and female, behavior, aviary size, method of raising, feeding, laying eggs, and growing of chick from hitching stage to six months were studied. Furthermore, the appropriate protein level was studied by comparing 15 percent with 20 percent protein in food ingredient for feeding green peafowl age six months or more. The results showed that any aviary sizes were applicable (aviary size: 2.5*6*2, 3*5*2, 3*9*2 and 4*12*2 m) but the larger cage was, the more eggs lay. For mating, breeding stock aged 4 years gave good productivity and the older were, the more eggs they laid 10 years age or more still gave eggs that could hatched. Hatching by hens gave better production than that by incubation because risk of using hatching machine always happens. The growth rate studied of the chicken aged between 1 day and 24 weeks revealed that female chick grew faster than male chick. Their sexual characteristics could be identified within 12 weeks. The animal like to feed on fifteen percent protein pellet foods more amount than that of 20 percent protein pellets in the pen. Otherwise, 15 percent protein pellets provided higher growth rate and less cost (per individual per day). Thus 15 percent protein of artificial food was more appropriate in the way of preferential and economical rate than that of 20 percent protein type. The result of this research can be used as a guideline for breeding green peafowl in captivity both conservation and commercialization purposes of the country.
