Recria de novilhos em pastagem com e sem suplementação proteico/energética nas águas: consumo, digestibilidade dos nutrientes e desempenho

Abstract: ResumoObjetivou-se com esse estudo avaliar o fornecimento de suplemento proteico e suplemento mineral na fase de recria de novilhos mestiços ½ Holandês x Zebu mantidos em pastagem de Brachiaria brizantha cv. Marandu, no período das águas e suas implicações sobre o consumo, a digestibilidade dos nutrientes e o desempenho animal. Foram utilizados 22 novilhos com média de sete meses de idade e peso corporal médio inicial de 164,09±12,13 kg, distribuídos em delineamento inteiramente casualizado, com dois tipos de … Show more

“…In general, tropical pastures may not meet the nutritional requirements of precocious animals so that they can express the genetic potential for maximum weight gain, even in the rainy season, favorable period for quality forage. Supplementation in the rainy season aims to provide potentially digestible nutrients and reduce dietary deficiencies of forages, allowing the animal to increase the intake of digestible nutrients, improving productivity and feed efficiency to reach carcass weight and composition for slaughter at a younger age, which would not be achieved only with the intake of forage and mineral supplementation (Dias et al, 2015).…”

“…Assim, a suplementação alimentar no período chuvoso tem como finalidade promover ganhos adicionais que não seriam alcançados apenas com o consumo de forragens e suplementação mineral, propiciando ao animal aumentar o consumo de nutrientes e melhorar a digestibilidade (Dias et al, 2015).…”
