Resumen
ALVAREZ-CARDONA, Fernanda et al. L-Arginine, Aspartate and Glutamate, and their relationship with the ewes’ reproduction. Review. Abanico vet [online]. 2019, vol.9, e929. Epub 30-Jul-2021. ISSN 2448-6132. https://doi.org/10.21929/abavet2019.929.
In most of livestock production systems, it is important to optimize reproductive activity to increase productive efficiency. This indicator depends on environmental factors such as nutrition, which regulates the onset of puberty, ovarian follicular development, oocyte quality and as a result, embryonic development. The purpose of animal nutrition strategies is to increase reproductive efficiency, to obtain better economic income in most of livestock production systems. Recent research reports that dietary supplementation with specific amino acids such as arginine, glutamine, leucine, glycine and methionine they have beneficial effects on survival and embryonic and fetal growth by regulating key signaling and metabolic pathways. In sheep production systems, supplementation with different routes with neurostimulatory amino acids such as L-Arginine, aspartate and glutamate, improves reproductive efficiency in females in a technical and economical way, with the aim of eliminating hormonal manipulation of the animals. Therefore, the objective of the present review of the literature is to describe the neurostimulatory function of amino acids and to know the neuroendocrine response in the hypothalamic-pituitary-ovarian axis in sheep to improve productive and reproductive variables.
