This research was conducted in order to determine chemical composition, gas production parameters, in vitro digestibility and ruminal degradability of Acroptilon repens at different phonological stages (vegetative, flowering and seeding) and its comparison with alfalfa hay and wheat straw in Completely Randomized Design. For this purpose, Acroptilon repens was prepared in three stages of growth...

Current ruminant feeding systems depend on knowledge of the composition of feeds and the rate and extent of degradation of feed organic matter (OM) and crude protein (CP) in the rumen. The effect of storage and preparation of samples on in vitro gas production and fermentation characteristics of two common forage species, namely alfalfa and ryegrass werestudied. Samples were prepared as fresh (...

The objective of this study was to determine the effect of irradiation of pomegranate seed (PS) on chemical composition, digestibility and kinetic of gas production. Pomegranate seeds were exposed to gamma ray (GR) and electron beam (EB) at doses of 5, 10, 15 and 20 kGy. Three ruminally fistulated rams were used for obtaining ruminal fluid for in vitro digestibility and gas production measuremen...

The aim of this study was to determine the relationship between gas produced through in vitro gas production test and microbial fuel cell (MFC) technique and introduce new assay for evaluation of ruminants feedstuffs. The treatments were 1) control diet (without whole cottonseed, monensin and vitamin E; CD), 2) diet containing 20.00% whole cottonseed (CSD), 3) diet including 20.00% who...

This study aimed to evaluate the potential of commercial enzymes cellulase (CE), xylanase (XY) and the combination of CE + XY to improve rumen fermentation of Guinea grass ecotype ‘A’ (Panicum maximum). The experiment was carried out in a randomized complete block design. In vitro incubations were performed with four doses of individual enzymes and their combinations (1:1 from each enzyme) as 5...
