NUTRIÇÃO DE VACAS DE CORTE NELORE PRIMÍPARAS NO PRÉ-PARTO E PÓS-PARTO: REVISÃO DE LITERATURA

Abstract

Cattle production in Brazil has shown significant improvements in some regions, as indicated by IBGE (2023), with increases in birth rates and reproductive efficiency. However, challenges remain, particularly in extensive systems, where prolonged anestrus and low pregnancy rates continue to negatively impact production. The implementation of nutritional strategies, particularly supplementation, is crucial to sustaining these advances and ensuring the sustainability of cattle production. Nutritional management of beef cows, both prepartum and postpartum, plays a critical role in maintaining health and reproductive efficiency, especially in primiparous cows. During the prepartum period, it is essential to intensify nutritional care to ensure proper fetal development and preparation for lactation. Postpartum, the focus should be on recovering body condition and supporting milk production, preventing negative energy balance that can impair reproductive health and productivity. Protein-energy and mineral supplementation has proven to be an effective strategy in improving productive and reproductive performance, directly influencing pregnancy rates and the return to estrous cycles, thereby enhancing overall system efficiency. Keywords: cattle production, dietary supplementation e productive efficiency.
