摘要

本研究旨在评价三种未开发的森林豆科树木叶片-毛毛终叶的影响。紫荆花(bahinia varegata L.)和单精子Butea Lam.;体外瘤胃发酵及甲烷产量的研究。这些树叶,连同Leucaena leucocephala(作为对照),采集自印度西孟加拉邦Purulia的Ajodhya山林地区。全混合日粮(TMRs)为基础饲粮,由精料混合物(40%)、玉米饲料(30%)和水稻秸秆(30%)组成。试验TMR基质分别以5.0%、7.5%和10.0%的添加量加入被试树木叶片(毛毛叶、杂色叶和单精叶),对照TMR中等量加入白头叶。体外分析评估了营养物的可降解性、发酵参数和甲烷产量。所有叶片的粗蛋白质含量为10%,总碳水化合物含量为65%,瘤胃不可降解蛋白质含量为16%,中性洗涤纤维含量为50%,所有tmr的体外真有机物降解率均超过55%。体外发酵瓶中挥发性脂肪酸(醋酸酯、丙酸酯和丁酸酯)和氮(N)组分(全氮、氨氮等)的产量均在正常生理范围内。将这些树叶添加到tmr中,特别是添加到总日粮的7.5%时,在体外支持良好的瘤胃发酵特征。值得注意的是,含毛毛柽柳叶的TMR具有良好的甲烷缓解作用。然而,需要进一步的研究来证实这些树叶对反刍家畜生产和繁殖性能的影响。

Modulating rumen fermentation and methane emissions in vitro with Terminalia tomentosa, Bauhinia variegata, and Butea monosperma forest tree leaves of Ajodhya hill areas, Purulia (India): a comparative study

This study aimed to evaluate the effects of three unexplored forest legume tree leaves—Terminalia tomentosa Roxb., Bauhinia variegata L., and Butea monosperma Lam.—on in vitro rumen fermentation and methane production. These tree leaves, along with Leucaena leucocephala (used as a control), were collected from the Ajodhya Hills Forest areas in Purulia, West Bengal, India. Total mixed rations (TMRs) were prepared as a basal substrate, comprising a concentrate mixture (40%), maize fodder (30%), and paddy straw (30%). The experimental TMR substrates were formulated by incorporating the test tree leaves (T. tomentosa, B. variegata, and B. monosperma) at inclusion levels of 5.0%, 7.5% and 10.0%, while the control TMR included L. leucocephala at equivalent levels. In vitro analyses assessed nutrient degradability, fermentation parameters and methane production. All tree leaves exhibited crude protein content > 10%, total carbohydrate content > 65%, rumen undegradable protein < 16%, and neutral detergent fiber < 50%, contributing to in vitro true organic matter degradability exceeding 55% across all TMRs. The production of volatile fatty acids (acetate, propionate, and butyrate) and the nitrogen (N) fractions (total-N, ammonia-N etc.) in the in vitro fermentation bottles were within normal physiological ranges. Incorporating these tree leaves into the TMRs, particularly at up to 7.5% of the total diet, supported favourable rumen fermentation profiles in vitro. Notably, the TMR containing T. tomentosa leaves exhibited a promising methane-mitigating effect. However, further research is required to confirm the impact of these tree leaves on the production and reproductive performance of ruminant livestock.

期刊介绍: Agroforestry Systems is an international scientific journal that publishes results of novel, high impact original research, critical reviews and short communications on any aspect of agroforestry. The journal particularly encourages contributions that demonstrate the role of agroforestry in providing commodity as well non-commodity benefits such as ecosystem services. Papers dealing with both biophysical and socioeconomic aspects are welcome. These include results of investigations of a fundamental or applied nature dealing with integrated systems involving trees and crops and/or livestock. Manuscripts that are purely descriptive in nature or confirmatory in nature of well-established findings, and with limited international scope are discouraged. To be acceptable for publication, the information presented must be relevant to a context wider than the specific location where the study was undertaken, and provide new insight or make a significant contribution to the agroforestry knowledge base
