This study was designed to determine the effect of location of the preovulatory dominant follicle and stage of ovarian follicle development on ovulation rate and embryo survival in alpacas. In Experiment 1, mature lactating alpacas were randomly assigned to one of two groups according to the loca...

The objective of this study was to determine the effect of leptin administration on the development, vascularization and function of Corpus luteum (CL) in alpacas submitted to pre-ovulatory fasting. Fourteen alpacas were kept in fasting conditions for 72 h and received five doses of o-leptin (2 m...

Gonadotrophin releasing hormone (GnRH) is commonly used in llamas to induce ovulation; however, the consequence of reduced doses of GnRH on luteinizing hormone (LH) release, ovulatory response, and subsequent corpus luteum (CL) development and function have apparently not been investigated. Hence...

The objectives of the study were to determine the effects of nutritional restriction on ovarian function in llamas. Mature female llamas were assigned randomly to a Control group, fed 100% of maintenance energy requirements (MER) (n = 8), or a Restricted group (n = 8) fed from 70% to 40% of MER u...
