Fermentation characteristics, digestibility and performance of ensiled swine waste, wheat straw and cane molasses fed to sheep

摘要: In four full-scale bunker silos were ensiled 16·5 tons of different mixtures swine waste, wheat straw and cane molasses. One mixture had 22% the other one 44% (DMB). Swine waste was collected from an open concrete growing-finishing feedlot. During first six weeks samples taken analyzed for pH, lactic acid, total coliforms, clostridia aerobic acid bacteria. After three months, opened evaluated physico-chemical, microbiological nutritional characteristics. Two performance trials on sheep conducted, to determine nutritive value silages with 22 evaluate inclusion silage at 20, 40, 60 80% (DMB) in diets. Dry matter, crude protein, detergent fiber neutral digestibilities determined eight sheep. Evaluation storage stability levels indicated low surface, bottom side wall fairly good 50 cm depth. Those a pleasant aroma appearance similar that quality haylage. Typical manure not present silages. Twenty-two percent reached average pH 4·4 while pH4·6. 7 days fermentation, coliforms completely destroyed. Clostridia bacteria tended be decreased by ensiling. Average daily gain digestibility protein higher fed than silage, but lower basal diet (P 0·01) < 0·01). dry matter intake increasing Feed efficiency between treatments
