Substituição da silagem de sorgo por silagem de capim-marandu: consumo, digestibilidade e ganho de peso

Abstract

O experimento foi conduzido com o objetivo de avaliar consumo, digestibilidade e desempenho de novilhas ¾ Zebu x Holandes submetidas a diferentes niveis de substituicao da silagem de sorgo por silagem de capim-marandu. Foram utilizadas vinte novihas com peso medio inicial de 346,25 kg, distribuidas em delineamento experimental inteiramente casualizado, com 5 repeticoes, onde no Tratamento 1- fracao volumosa da dieta composta por 100% de silagem de sorgo; Tratamento 2- fracao volumosa da dieta composta por 70% de silagem de sorgo e 30% de silagem de capim-marandu; Tratamento 3- fracao volumosa da dieta composta por 30% de silagem de sorgo e 70% de silagem de capim-marandu; Tratamento 4- fracao volumosa da dieta composta por 100% de silagem de capim-marandu. Juntamente com os volumosos foi adicionado concentrado na proporcao de 1,2 % do peso vivo, sendo as dietas isoproteicas, tendo como unica fonte de variacao os diferentes volumosos e suas proporcoes em cada tratamento. O aumento dos niveis de substituicao da silagem de sorgo por silagem de capim-marandu aumentou consumo de materia mineral e diminuiu consumo de carboidratos nao fibrosos e nutrientes digestiveis totais, porem nao alterou consumo de materia seca, proteina bruta, extrato etereo e fibra em detergente neutro. Interferiu de forma linear decrescente nos coeficientes de digestibilidade da materia seca, proteina bruta, fibra em detergente neutro e extrato etereo, prejudicando o ganho de peso das novilhas.
