Valor nutritivo e características fermentativas de silagens de capim-elefante com adição de casca de café

Abstract: RESUMOsilos. In the ensiling process, the forage packing density was 500 kg/m 3 . It was observed increase of DM, acid detergent fiber, acid detergent insoluble nitrogen, and lignin concentration, as a function of coffee hull levels. Crude protein showed quadratic behaviour, estimating maximum CP value of 9.9% for the 16.4% coffee hull addition level. Neutral detergent fiber reduced linearly and silage lactic acid concentration showed quadratic behaviour as a function of coffee hull levels, estimating maximum … Show more

“…Zanine et al (20) observed an increase of 51.7% in protein value when 15% wheat bran was added to the silage of elephant grass, which is in accordance with the results of this work. The results of this study are similar to studies using other additives such as cocoa bran Carvalho et al (5) and coffee shells Carvalho et al (6) that promote an increase in the protein content of silage. Thus, both the peanut cake and other additives show positive results for improving the protein content of grass silages to meet the nutritional requirements of animals, especially during periods of quality food scarcity.…”

“…Alternatives of additives in the ensiling of tropical grass, have been utilized to increase the dry matter content of silage Carvalho et al (5); Carvalho et al (6) and to provide nonfiber carbohydrates, Andrade and Melotti (7); Ferreira et al (8). A good additive for ensiling tropical grasses should have high dry matter content, capacity for water absorption, high nutritional value, good flavor, high content of soluble carbohydrates, easy manipulation, Neiva and Vasconcelos (1).…”

“…can be rather useful to this grass ensilage process, once the DM content in the recommended cutting age (between 50 and 70 days of growth) is between 80 and 85% below the recommended (Lavezzo et al, 1989;Carvalho et al, 2007). Moreover, Silva et al (2008b) observed that there was variability for the character DM content in different Pennisetum sp.…”

“…Neste trabalho verificou-se a preferência dos animais pelo volumoso, rejeitando o farelo de cacau que ficava no fundo do cocho. É possível que o cheiro acentuado de chocolate no farelo de cacau tenha favorecido o baixo consumo, uma vez que a silagem apresentou boa aparência e pH dentro da faixa recomendada para silagens bem fermentadas (Carvalho et al, 2007;Carvalho et al, 2008). Do mesmo modo, Silva et al (2005) realizaram estudos com cabras leiteiras alimentadas com dietas contendo 15 e 30% de farelo de cacau ou torta de dendê no concentrado e não verificaram diferenças nos coeficientes de digestibilidade da PB, de modo que a digestibilidade da PB da dieta contendo 15% de farelo de cacau no concentrado foi de 58,60%.…”
