Resumo: The aim of this study was to evaluate the composition, voluntary intake, and digestibility of the diet of Holstein cows, as well as milk yield and milk composition as a function of different roughage sources used under experimental feeding conditions in Brazil, through meta-analysis. The database of this study consisted of 109 experiments with 424 treatments of 3,903 lactating Holstein cows. The data were obtained from studies published between January 2000 and December 2015, and were evaluated by variance analysis. Lactating dairy cow diets with a single source of roughage other than corn silage resulted in lower voluntary intake, milk yield, and differences in milk composition, compared to diets based on corn silage or the combination of two roughages, probably due to reduced nutrient digestibility. Diets based on corn silage are distinguished by feed efficiency, milk yield, and composition. Diets based on the combination of two roughage sources are similar with respect to milk yield and composition, compared to diets based on corn silage; whereas, diets with a single source of roughage (other than corn silage), even when containing a higher proportion of concentrate, led to reduced voluntary intake, milk yield, and food efficiency due to the lower utilization of the nutrients. Diets based on corn silage in general allow a higher proportion of roughage in the diet due to energy density.

Neste estudo, a base de dados ficou composta de 109 experimentos, com 424 tratamentos, envolvendo 3.903 vacas em lactação da raça Holandês, informações oriundas de publicações compreendidas entre janeiro de 2000 e dezembro de 2015. Os dados foram avaliados pela análise de variância, considerando a distribuição das variáveis resposta. Dietas com uma única fonte de volumoso que não a silagem de milho apresentaram consumo voluntário, produção e composição do leite inferior as dietas baseadas em silagem de milho e na combinação de dois volumosos em função da reduzida digestibilidade dos nutrientes. As dietas a base de silagem de milho destacam-se pela eficiência na produção e composição do leite. A utilização de dieta baseadas na combinação de dois volumosos assemelham-se em produção e composição do leite com as dietas a base de silagem de milho, enquanto que as dietas com uma única fonte de volumoso que não a silagem de milho, mesmo com maior proporção de concentrado, apresenta consumo, produção de leite e eficiência alimentar inferiores em função do menor aproveitamento dos nutrientes. Dietas a base de silagem de milho permitem maior proporção de volumoso na dieta em função da densidade energética.UEL2018-11-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3210710.5433/1679-0359.2018v39n6p2749Semina: Ciências Agrárias; Vol. 39 No. 6 (2018); 2749-2760Semina: Ciências Agrárias; v. 39 n. 6 (2018); 2749-27601679-03591676-546Xreponame:Semina.
