Chemical composition and fermentation characteristics of sugar cane silage enriched with detoxified castor bean meal

This experiment was designed to evaluate the effects of the inclusion of detoxified castor bean meal (CM) content on the chemical-bromatological composition, as well as the fermentation characteristics and dry matter losses of sugarcane silage. The treatments consisted of four levels (0, 7, 14 and 2...

Description
Summary:	This experiment was designed to evaluate the effects of the inclusion of detoxified castor bean meal (CM) content on the chemical-bromatological composition, as well as the fermentation characteristics and dry matter losses of sugarcane silage. The treatments consisted of four levels (0, 7, 14 and 21% natural matter) of addition of castor bean meal. The design was completely randomized, with five replicates. The material was ensiled in PVC silos of 50-cm in height and 10-cm in diameter, which were opened after 60 days. The density of fodder maintained in the silos was equal to 750kg of natural matter/m3. In order to quantify the gas and effluent losses, the silos were weighed at the beginning and at the end of the experiment. The addition of castor bean meal has increased the levels of DM and crude protein and reduced the levels of neutral detergent fiber, N-NH3, ethanol, and gas and effluent losses from silages, but did not affect pH values. During ensiling, alcoholic fermentation was controlled with the inclusion of the additive. O experimento foi desenvolvido para avaliar os efeitos da inclusão de níveis de farelo de mamona destoxificado sobre a composição químico-bromatológica, as características fermentativas e as perdas de matéria seca da silagem de cana-de-açúcar. Os tratamentos consistiam em quatro níveis (0, 7, 14 e 21% da matéria natural) de inclusão do farelo de mamona. O delineamento foi inteiramente ao acaso, com cinco repetições. Foram usados silos de PVC, com 50cm de altura e 10cm de diâmetro, para a produção das silagens, que foram abertos após 60 dias. A densidade de forragem nos silos foi correspondente a 750kg de matéria natural/m3. Os silos foram pesados no início e ao final do período experimental para quantificar as perdas por gases e efluentes. A inclusão de farelo de mamona elevou os teores de MS e proteína bruta e reduziu os teores de fibra em detergente neutro, N-NH3, etanol e as perdas por gases e efluentes das silagens, não ocasionando efeito nos valores de pH. A fermentação alcoólica durante a ensilagem foi controlada com a inclusão do aditivo.
