Abstract The objective of this study is to evaluate the bromatological composition, carbohydrate fractionation, in vitro digestibility and gas production of varieties of forage cactus of the genus Opuntia, associated with different phenological phases. The experiment was conducted in a completely randomized design in a 5 × 3 factorial arrangement consisting of five forage cactus varieties of the genus Opuntia ((IPA-20 (Opuntia ficus-indica Mill), Gigante (Opuntia ficus-indica Mill), Erect Prickly Pear (EPP) (Opuntia stricta Haw), African Prickly Pear (APP) (Opuntia undulata) and F-08 (Opuntia atropes Rose)). and three phenological phases (young, intermediate and mature). The concentrations of neutral detergent fiber and the C ratio of carbohydrates were lower in the Erect Prickly Pear (EPP) variety, in this same variety, a higher proportion of pectin was observed along with the giant variety and higher in vitro digestibility, with similar digestibility for the African Prickly Pear (APP) and F-08. The concentration of total carbohydrates was higher in the IPA-20 variety since the gas production adjusted by the bicompartmental model was higher for APP. Was observed in all varieties greater concentration of neutral detergent fiber and the C fraction of the carbohydrates in the mature cladodes. In vitro digestibility of mature phase was also superior in all varieties except APP. The Erect Prickly Pear and African Prickly Pear varieties present best nutritional value for feeding ruminants and mature phase is the least relevant.

不同物候期仙人掌属草料仙人掌:营养价值

摘要 本研究的目的是评估仙人掌属草料仙人掌品种在不同物候阶段的微生物组成、碳水化合物分馏、体外消化率和产气量。该实验是在一个完全随机设计的 5 × 3 因子排列中进行的,由仙人掌属的五种饲料仙人掌品种((IPA-20(仙人掌)、Gigante(仙人掌)、直立刺仙人掌)组成。 Pear (EPP) (Opuntia stricta Haw)、African Prickly Pear (APP) (Opuntia undulata) 和 F-08 (Opuntia atropes Rose))和三个物候阶段(幼、中、成熟)。中性洗涤纤维和在 Erect Prickly Pear (EPP) 品种中,碳水化合物的 C 比率较低,在同一品种中,观察到更高比例的果胶以及巨型品种和更高的体外消化率,非洲仙人球 (APP) 和 F-08 的消化率相似。IPA-20 品种的总碳水化合物浓度较高,因为 APP 的双室模型调整的气体产量较高。在所有品种中都观察到较大浓度的中性洗涤纤维和成熟枝条中碳水化合物的 C 部分。除APP外,所有品种的成熟期体外消化率也均优于其他品种。直立仙人球和非洲仙人掌品种对喂养反刍动物的营养价值最高,成熟期的相关性最低。对非洲仙人掌 (APP) 和 F-08 具有相似的消化率。IPA-20 品种的总碳水化合物浓度较高,因为 APP 的双室模型调整的气体产量较高。在所有品种中都观察到较大浓度的中性洗涤纤维和成熟枝条中碳水化合物的 C 部分。除APP外,所有品种的成熟期体外消化率也均优于其他品种。直立仙人球和非洲仙人掌品种对喂养反刍动物的营养价值最高,成熟期的相关性最低。对非洲仙人掌 (APP) 和 F-08 具有相似的消化率。IPA-20 品种的总碳水化合物浓度较高,因为 APP 的双室模型调整的气体产量较高。在所有品种中都观察到更高浓度的中性洗涤纤维和成熟枝条中碳水化合物的 C 部分。除APP外,所有品种的成熟期体外消化率也均优于其他品种。直立仙人球和非洲仙人掌品种对喂养反刍动物的营养价值最高,成熟期的相关性最低。在所有品种中都观察到较大浓度的中性洗涤纤维和成熟枝条中碳水化合物的 C 部分。除APP外,所有品种的成熟期体外消化率也均优于其他品种。直立仙人球和非洲仙人掌品种对喂养反刍动物的营养价值最高,成熟期的相关性最低。在所有品种中都观察到较大浓度的中性洗涤纤维和成熟枝条中碳水化合物的 C 部分。除APP外,所有品种的成熟期体外消化率也均优于其他品种。直立仙人球和非洲仙人掌品种对喂养反刍动物的营养价值最高,成熟期的相关性最低。
