The objective of this study was to evaluate storage methods of cactus pear as a way of conservation for use in animal feeding. The randomised experimental design composed twelve treatments and three replications. Three cactus pear genotypes, Nopalea cochenillifera genotype Doce and Baiana and Opuntia tuna genotype Orelha de Elefante Mexicana (OEM), were stored in natura (0, 30 and 60 days after harvest) and as silage. There was a significant difference (p < 0.05) on the chemical and mineral composition of the material stored in natura versus silage. OEM cactus pear presented the highest crude protein content when stored in natura for 0, 30 and 60 days. The highest lignin content was observed in cactus pear OEM when stored in natura for 30 and 60 days after harvest. Macro- and micronutrient contents were within the recommended ranges for ruminant feeding regardless of the cactus pear genotype and storage method. The cactus pear genotypes Doce and Baiana, and genotype OEM can be stored as silage and in natura form for up to 60 days after harvest without compromising the quality of the feed for ruminants.

用于动物饲养的仙人掌梨基因型的储存方法

本研究的目的是评估仙人掌梨的储存方法,作为一种用于动物饲养的保存方式。随机实验设计由十二个处理和三个重复组成。三种仙人掌梨基因型,Nopalea cochenillifera 基因型 Doce 和 Baiana 以及 Opuntia 金枪鱼基因型 Orelha de Elefante Mexicana (OEM),储存在自然环境中(收获后 0、30 和 60 天)并作为青贮饲料。储存在自然与青贮饲料中的材料的化学和矿物组成存在显着差异 (p < 0.05)。OEM 仙人掌梨在自然环境中储存 0、30 和 60 天时,其粗蛋白含量最高。仙人掌梨 OEM 在收获后在自然中储存 30 天和 60 天时观察到最高的木质素含量。无论仙人掌梨基因型和储存方法如何,宏量和微量营养素含量都在反刍动物饲养的推荐范围内。仙人掌梨基因型 Doce 和 Baiana 以及基因型 OEM 可以在收获后以青贮饲料和自然形式储存长达 60 天,而不会影响反刍动物饲料的质量。
