A poor nutritional state may explain the low fertility rates of domestic camelids from Puna herds. The objective of this study was to determine the relationship between the nutritional state of alpacas before the breeding period and their reproductive success. The body live weight (BLW) and body ...

Energy unbalance may be the cause of low fertility rates found in vicunas. The objective of this study was to estimate the temporal variation of the nutritional status in pregnant vicunas from a herd kept under captivity in the Chilean High Andes. The hypothesis under study is that animals are ab...

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...

The objective was to determine the effect of energy diet restriction on energy balance, systemic leptin and corpus luteum (CL) vascularization, development, and function in South American camelids. In experiment 1, adult llamas were randomly assigned to receive a diet of 70% of their maintenance ...
