Práctica empresarial y apoyo técnico con suplementación en el manejo nutricional, productivo y metabólico de novillas Nelore en pastoreo, en los periodos pre y posparto en la Unidad de Ensino, Presquisa e Extensão em Gado de Corte (UEPE-GC) de la Universidade Federal de Viçosa.

Abstract

Supplementation in the pre- and postpartum periods is an alternative that helps with the nutritional requirements of the cow because in these stages an energy imbalance is generated on the reproductive and productive parameters of the animal, consequently, the productive performance of the animal increases. grazing heifers. The purpose of this internship was to provide technical support in the nutritional and productive management of supplemented grazing Nelore heifers during pre- and postpartum at the Unidade de Ensino, Pesquisa e Extensão em Gado de Corte (UEPE-GC) of the Universidade Federal de Viçosa, Brasil. For this practice, a total of 43 animals were used, distributed 25 animals and 18 animals in the farm and the grota respectively, with a weight of ± 550 kg. The treatments evaluated were: mineralized salt, DDG and mineralized salt, urea and DDG. Supplementation presented a significant variation in the prepartum stage with the treatments used. However, changes in body condition occur, presenting weight loss during childbirth and an energy imbalance. In conclusion, the supplementation alternative is a relevant tool in the prepartum and postpartum periods, DDG improves body weight and body condition score but does not affect the weight of the calf at birth. However, it improves the productive performance of the animals.
