Resumo
A fruticultura produz resíduos tanto na industrialização da fruta como na venda in natura. O abacaxi pérola, produzido para venda in natura, gera grande quantidade de restos culturais que tem potencial para utilização na alimentação de ruminantes na forma de silagem. O presente trabalho avaliou o valor nutricional da silagem de restos culturais de abacaxi pérola. O experimento foi conduzido no setor de Bovinocultura de Leite da Faculdade de Ciências Agrárias e Veterinárias da UNESP, Campus de Jaboticabal, São Paulo. Utilizou-se um delineamento inteiramente casualizado em esquema fatorial 2 x 4 com dois tamanhos de partículas (20 e 50 mm) e 4 tempos de fermentação (30, 60, 90 e 120 dias após ensilagem) com 4 repetições. A cada tempo de fermentação foram coletadas 8 amostras para determinação da matéria seca (MS), matéria mineral (MM), matéria orgânica (MO), proteína bruta (PB), extrato etéreo (EE), fibra em detergente neutro (FDN), fibra em detergente ácido (FDA), hemicelulose (HEM), nutrientes digestíveis totais (NDT), carboidratos totais (CT), carboidratos não fibrosos (CNF) e valores de pH. A digestibilidade in vitro da matéria seca, fibra em detergente neutro e fibra em detergente ácido (DIVFDA) foram determinados a partir de um ensaio realizado em Fermentador Ruminal Ankom® (“Daisy-II Fermenter”), em esquema fatorial 2 x 2, com 2 tempos de fermentação (30 e 90 dias) e dois tamanhos de partículas. As médias dos dados observados de cada tratamento foram submetidas à análise de variância e comparadas através do teste Tukey, ao nível de 5% de probabilidade. Não houve interação (P>0,05) entre os teores de MS, MO, PB, FDN, FDA, HEM, MM, NDT, CT e CNF, exceto para o teor de EE e pH (P<0,05). Verificou-se que o teor de EE aumentou 42% quando a silagem permaneceu armazenada durante 60 dias com tamanhos de partículas de 50 mm. Houve interação (P<0,05) aos 90 dias de fermentação em relação ...
Fruit farming produces waste both from the sale to the consumer and from the industrialization of fruit. The Pérola pineapple, produced for sale in natura, generates large amounts of crop residue that have potential for use in ruminant feed as silage. This study evaluated the nutritional value of the crop residue silage of the Pérola pineapple. The experiment was conducted at the Dairy Cattle Department of the Agricultural and Veterinary Sciences College, UNESP, Jaboticabal Campus, São Paulo. A completely randomized 2 x 4 factorial design with two particle sizes (20 and 50 mm) and 4 fermentation periods (30, 60, 90 and 120 days after ensiling) with 4 replications was used. For each fermentation period, 8 samples were collected and analyzed for dry matter (DM), mineral matter (MM), organic matter (OM), crude protein (CP), ether extract (EE), neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose (HEM), total digestible nutrients (TDN), total carbohydrates (TC), non-fiber carbohydrates (NFC) and pH values. The in vitro digestibility dry matter (IVDDM), neutral detergent fiber (IVDNDF) and acid detergent fiber (IVDADF) were determined by a Rumen Fermenter Ankom ® trial (Daisy Fermenter-II), in a 2 x 2 factorial scheme with 2 periods of fermentation (30 and 90 days) and two particle sizes. The averages of the observed data from each treatment were subjected to analysis of variance and compared by means of the Tukey test at 5% probability. There was no interaction (P>0,05) between DM, OM, CP, NDF, ADF, HEM, MM, TDN, TC and NFC, except for the content of EE and pH (P<0,05). That the content of EE increased by 42% when the silage remained stored for 60 days with particle sizes of 50 mm was observed. There was interaction (P<0,05) after 90 days of fermentation for the two sizes of particles when pH values were 4,19 for 20 mm and 4,15 for 50 mm (P<0,05). The IVDADF increased 38,11% when the silage remained stored 90 days ...
