Abstract

The objective of this research was to investigate the effects of supplementation of the paper mulberry leaf-based diets with concentrate on growth performance, preovulatory follicle diameter, response to estrous synchronization treatment, and productivity in Lao-native goats. Group 1, female goats were given the paper mulberry leaves (PML) as the basal diet (PML diet; n=12). Group 2, female goats were given the PML as the basal diet and 400 g/head/day of the concentrate (PML+C diet; n=12).The periods of estrus were synchronized with controlled intravaginal drug release (CIDR) devices inserted for 14 days and injections of 300 IU of human chorionic gonadotropin upon the removal of CIDR devices.The ovaries were scanned on the day of CIDR removal and every 12 h after the withdrawal of CIDR to evaluate the preovulatory follicle diameter. The positive changes in the live weight of the female goats in the PML+C group were greater than those of the PML group. The proportion of synchronized goats displaying estrus at 48 h after the withdrawal of CIDR was significantly higher in the group that received the PML+C diet than in the group that received the PML diet. The productivity tended to be greater in the goats that received the PML+C diet than in goats that received the PML diet. Thus, these data highlight that the positive changes in the live weight, the proportion of animals exhibiting estrus, and the preovulatory follicle size of synchronized Lao-native goats were increased by the addition of the concentrate in diets based on PML.
