摘要

本试验旨在评价生物质高粱与仙人掌梨混合青贮对发酵特性和营养价值的影响。青贮饲料包括饲草高粱。体积，生物量高粱cv。BRS 716, BRS capiau草，60%生物质高粱BRS 716与40%印度仙人掌(“Gigante”)仙人掌梨(以新鲜物质为基础)的混合物，以及60%的BRS capiau草与40%印度仙人掌(“Gigante”)仙人掌梨(以新鲜物质为基础)的混合物。试验采用随机试验设计，5个处理，8个重复。气体损失最高(P < 0.01)，干物质回收率最低(DMR;P < 0.01)，与加仙人掌梨青贮的青贮牧草相比，P < 0.01)。仙人掌梨青贮生物量高粱的乳酸浓度比Volumax高粱青贮乳酸浓度高49.96%。Volumax高粱和BRS 716生物量青贮DM含量较高(P < 0.01);平均值33.44%)。不同青贮之间DM的潜在可降解不溶性部分差异不显著(P = 0.24)，平均为51.75%。生物量高粱与仙人掌梨混合青贮损失较小，DMR较高。

Quality of mixed silages of sorghum, BRS Capiaçu grass, and cactus pear in a semiarid region of Brazil

The study aimed to assess the impact of mixed silages of biomass sorghum and BRS Capiaçu with cactus pear on the fermentative profile and nutritional value. The silages included forage sorghum cv. Volumax, biomass sorghum cv. ‘BRS 716,’ BRS Capiaçu grass, a mix of 60% biomass sorghum ‘BRS 716’ with 40% Opuntia ficus indica Mill (‘Gigante’) cactus pear (based on fresh matter), and a mix of 60% BRS Capiaçu grass with 40% Opuntia ficus indica Mill (‘Gigante’) cactus pear (based on fresh matter). The experiment followed a randomized experimental design with five treatments and eight repetitions. The highest gas losses (P < 0.01) and lowest dry matter recovery (DMR; P < 0.01) were observed in the BRS Capiaçu grass and BRS Capiaçu grass with cactus pear silages. The lactic acid concentration in the biomass sorghum with cactus pear silage was 49.96% higher than in the Volumax sorghum silage . Volumax sorghum and ‘BRS 716’ biomass silages demonstrated higher DM contents (P < 0.01; mean 33.44%) compared to other silages. There was no significant difference (P = 0.24) among silages regarding the potentially degradable insoluble fraction of the DM, with a mean of 51.75%. The mixed silage of biomass sorghum with cactus pear exhibited lower losses and higher DMR.

期刊介绍： Journal of Applied Animal Research (JAAR) is an international open access journal. JAAR publishes articles related to animal production and fundamental aspects of genetics, nutrition, physiology, reproduction, immunology, pathology and animal products. Papers on cows and dairy cattle, small ruminants, horses, pigs and companion animals are very welcome, as well as research involving other farm animals, aquatic and wildlife species. In addition, manuscripts involving research in other species that is directly related to animal production will be considered for publication.
