The effects of in ovo administration of β-hydroxy-β-methylbutyrate (HMB) on broiler performance, intestinal health, and immunity were investigated. At day 18 of incubation, fertile eggs were divided into negative (no injection) and positive (physiologic serum injection) controls and three HMB treatment groups. HMB solution was injected at 0.1% (Group 1), 0.2% (Group 2), and 0.3% (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 (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 (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 (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 (HMB 0.2%).

The aim of the study was to investigate the relation between porcine epidemic diarrhea (PED) and porcine reproductive and respiratory syndrome virus (PRRSV). Here, we constructed a dynamic clinical experimental model in which sows were infected with PRRSV. The stability of the experimental model was surveyed by detecting the levels of antibodies against classical swine fever virus (CSFV) or PRRSV, respectively. In both group A (infected group) and group B (healthy group), the CSFV antibody level was not significantly different (P > 0.05). In group B, the PRRSV antibody level was also not significantly different (P > 0.05) at the three times …
