This article aims to review recent progress and update on utilization of exogenous fibrolytic enzymes in fiber fermentation, degradation, and digestions and nutritive and anti-nutritional characteristics of whole legume faba bean and its silage. The study focused on strategies to improve the utilization and bioavailability of fiber through pre-treating exogenous fibrolytic enzymes. The review includes features of nutrition and anti-nutritional factors and environment impact, forage fiber fermentation, degradation and digestion, legume bean in various diets, use of exogenous enzyme and factor affecting enzyme action in fiber digestion as well as exogenous enzyme response. This review also provides very recent research on effects of fibrolytic enzyme on rumen degradation characteristics of dry matter and fiber of whole plant faba bean silage and effect of exogenous fibrolytic enzyme derived from on lactational performance, feeding behavior, rumen fermentation and nutrient digestibility in dairy cows fed whole plant faba bean silage-based diet. This study provides an insight on nutritive and anti-nutritive characteristics of whole legume bean and its plant silage and utilization of exogenous fibrolytic enzymes in fiber fermentation, degradation, and digestions.
本文旨在综述外源纤维分解酶在纤维发酵、降解及消化方面的最新进展与更新情况，以及全粒豆类蚕豆及其青贮饲料的营养和抗营养特性。该研究聚焦于通过预处理外源纤维分解酶来提高纤维利用率和生物有效性的策略。综述内容包括营养和抗营养因子的特征、环境影响、饲草纤维发酵、降解及消化、不同日粮中的豆类、外源酶的使用以及影响纤维消化中酶作用的因素和外源酶反应。本综述还提供了关于纤维分解酶对全株蚕豆青贮饲料干物质和纤维瘤胃降解特性影响的最新研究，以及源自[此处原文缺失相关内容]的外源纤维分解酶对以全株蚕豆青贮饲料为基础日粮的奶牛泌乳性能、采食行为、瘤胃发酵和养分消化率的影响。本研究深入探讨了全粒豆类及其青贮饲料的营养和抗营养特性，以及外源纤维分解酶在纤维发酵、降解及消化中的应用。
