Abstract :The effects of in ovo administration of β-hydroxy-β-methylbutyrate insert ignore into journalissuearticles values(HMB); on broiler performance, intestinal health, and immunity were investigated. At day 18 of incubation, fertile eggs were divided into negative insert ignore into journalissuearticles values(no injection); and positive insert ignore into journalissuearticles values(physiologic serum injection); controls and three HMB treatment groups. HMB solution was injected at 0.1% insert ignore into journalissuearticles values(Group 1);, 0.2% insert ignore into journalissuearticles values(Group 2);, and 0.3% insert ignore into journalissuearticles values(Group 3); concentrations. There were no significant differences between the groups for live weight gain, feed conversion rate, and hot carcass, breast meat, liver, and heart weight. However, the gizzard weight in Group 1 was significantly higher than those in the other groups insert ignore into journalissuearticles values(P < 0.05);. Although the intestinal villi lengths in the treatment Groups 1 and 3 on day 20 were greater than those in the control groups insert ignore into journalissuearticles values(P < 0.01);, at the end of the experiment there were no significant differences among the groups. For antibody levels, the differences between groups on days 4 and 42 were highly significant insert ignore into journalissuearticles values(P < 0.01);, and the antibody levels in Group 2 were higher than those in the other groups. Separately, growth performance and antibody levels were positively correlated with the length of villi in Group 2 insert ignore into journalissuearticles values(HMB 0.2%);.
