Resumo Objetivou-se avaliar as características estruturais, a produção de massa seca e a composição bromatológica de cultivares de Brachiaria e Panicum. O estudo foi conduzido em casa-de-vegetação, em delineamento em blocos casualizados, com cinco tratamentos, sendo três cultivares de Brachiaria (B. decumbens cv. Basilisk, B. brizantha cv. Marandu e cv. Xaraés) e dois cultivares de Panicum (P. maximum cv. Momba...
ABSTRACT - The objective of this study was to evaluate the effect of replacing wheat bran by spineless cactus (0, 25, 50, 75, and 100%) in sugar cane-based diets on intake and nutrient digestibility and ruminal parameters of sheep. Five sheep (Santa Inês; average initial weight of 34.0±3.6 kg) were fitted with cannulas in the rumen and then assigned to a 5 × 5 Latin square design. The maximum dry matter (DM; 14...
ABSTRACT The objective of this study was to evaluate the effect of alternative protein sources (castor bean cake, sunflower cake, and sunflower seed) to soybean meal on the intake and performance of 40 lambs, initially weighing 19.8±1.84 kg, fed diets based on Tifton grass hay. The experimental design was completely randomized blocks. There were no differences in the nutrient intake of castor bean diets compare...
ABSTRACT The effect of replacing wheat bran with spineless cactus (0, 25, 50, 75, and 100%) in sugar cane-based diets on the intake of nutrients, feeding behavior, and rumen digestibility of steers was assessed using digested samples collected from the omasum. Five crossbred steers (1/2 Holstein-Zebu) were fitted with cannulas in the rumen and then assigned to a 5 × 5 Latin square design. Samples of omasal dige...
The objective of this study was to assess the effect of applying N and K2O at different times after harvest on the structure and production characteristics of Marandu and Xaraés cultivars of Brachiaria brizantha. Two greenhouse 4 × 2 factorial experiments using a randomized block design with eight treatments and four replicates were carried out. In experiment 1, the plants in pots were fertilized weekly with 50...
Avaliaram-se a produtividade de matéria seca (MS), proporção de lâminas e composição bromatológica de Brachiaria spp., colhidas com 42 dias de rebrotação, em Diamantina, MG. Para a determinação dos teores de MS, PB, FDN, FDA e lignina utilizaram-se o esquema em parcelas subsubdivididas, no DIC, com quatro repetições. Nas parcelas foram distribuídas as cultivares Basilisk, Marandu, Xaraés, Llanero e B. humidicol...
Objetivou-se estudar o efeito do tamanho da presa, com ou sem adição de ração na larvicultura do pacamã (Lophiosilurus alexandri), espécie nativa da bacia do Rio São Francisco ameaçada de extinção. As larvas foram cultivadas em aquários por 16 dias e alimentadas com zooplâncton natural, selecionado em malhas de 650 e 1.300 µm, com ou sem ração. A oferta de zooplâncton de maior tamanho resultou em melhor desenvo...
