Influence of breastfeeding and postpartum anestrus on the reproductive efficiency of the bovine female

Abstract: A eficiência reprodutiva de um rebanho de cria é uma ferramenta de suma importância quando se quer aperfeiçoar a atividade pecuária de uma fazenda. Para avaliar a eficiência reprodutiva das fêmeas bovinas, algumas características devem ser levadas em consideração, como o número de concepções e bezerros nascidos em um ano, bem como o número de bezerros desmamados, para que isso aconteça é necessário que cada vaca consiga parir um bezerro a cada de 12 meses, isso só será possível se o período de serviço desses a… Show more

“…We hypothesized that lambs in treatment-1 had a longer suckling period; thus, ewes had a longer postpartum anestrus. The presence of lambs associated with a longer period of sucking generated neural, sensory, and olfactory metabolic responses that may have inhibited LH synthesis and, consequently, decreased oocyte maturation (Risques et al, 2020). In treatment-2, the shorter sucking time may promote greater prolactin control through hypothalamic factors.…”

“…is essential for the best productive and sanitary performance of this category (Melo et al, 2019). In addition, protein-energy supplementation for lambs finished in these same pastures efficiently reduced the age at slaughter and ensured high carcass and meat quality with productivity close to that observed in feedlots (Silva et al, 2020;Silva et al, 2022).…”
