Resumo: There have been few studies on the use of diets and strategies to reduce the postpartum anoestrus in dairy goats, especially in tropical semi-arid regions. This review discusses the factors influencing the return of postpartum ovarian activity in goats. The duration of puerperal anoestrus in goats directly affects the productivity of the herd. During the postpartum period, goats showed a puerperal anoestrus due to physiological changes in their reproductive tract to achieve a new conception. Anoestrus occurs as a result of tissue renewal in the uterus (uterine involution) which is associated with the return of cyclic ovarian activity, and is influenced by factors such as suckling of the offspring, the period of lactation, social interactions, body condition score (BCS) before and after birth, intensity of negative energy balance (NEB) and stress from adverse climatic conditions for example; the heat. The period of anoestrus can be extended, due to the delay in the cyclic reproductive activity in the puerperium. To minimize the negative effects of postpartum anoestrus on productivity, we recommend a mating season and a plan for the kidding period, as well as a program to increase the BCS during pregnancy so that the animals will have a better BCS at parturition and a nutritional plan for the lactation period.
