Reproductive Strategies for Goat Production in Adverse Environments

Chapter

Abstract

Reproductive patterns in goats can be artificially manipulated by different strategies based in the control of endocrine system by the exogenous administration of hormonal compounds, or by manipulation of specific environmental factors. This chapter summarizes the main information on the possible on-farm applications of low cost-demanding techniques, as well as on advanced reproductive technologies that have greater impact on goat production systems. The recent improvement in the knowledge and manipulation of ovarian follicular dynamics in goats is the basis for the development of novel pharmacological protocols for fixed-time artificial insemination with which high pregnancy rate without estrus detection can be achieved. Alternatively, social-environmental factors can be managed to induce ovulations in anestrous; e.g., the male effect, female effect, or light control regimens, which require estrus detection or natural mating. In addition, the chapter updates the knowledge on advanced reproductive technologies related to superovulation for in vivo-derived embryos and to follicular aspiration for in vitro-produced embryos. Both technologies have been strongly improved in the last years and currently may be applied in farm conditions with positive results. Altogether, these strategies conform a complete toolbox for the management of goat production in different conditions, offering one tool for each need.
