this study was done to investigate the nutritive value of festocaovina, agrostisgiganta and avena sativa using sheep rumen and feces liquor as sources of micro-organism through gas production method. rumen and feces liquor were collected from three fistulated sheep. rangeland species sampling was randomly conducted from different areas of guilan province. all the collected samples were initiall...

The objective of this study was to determine the effects of physically effective neutral detergent fiber (peNDF) content in total mixed ration (TMR) on dry matter intake, digestibility, and chewing activity in fattening Hanwoo (Bos taurus coreanae) heifers. The experiment was designed as a replicated 3×3 Latin square using 12 heifers. Fattening heifers were offered one of three diets [high (T1)...

Background and Objectives: According to recent research, olive leaf (OL) has demonstrated significant properties, including antibacterial, antiviral, anticancer, gastro protective and cardio protective properties. The aim of this study was to investigate the chemical composition, and fatty acid composition (FAC) of OL of Marry variety cultivated in Jiroft province of Iran. This study also attem...

Maize forage is commonly used as silage in milk and beef cattle livestock production systems. Despite the wide variety of maize hybrids with high potential for grain production, few available have been developed exclusively aptitude. The present study aimed to select S3 progenies derived from single hybrid AS1572 based on combining ability traits topcrosses testers AG8025, 70.H26.1, MLP102. 135...

Packing density has a significant influence on the outcome of ensiling forage. In this study, we aim to investigate effect packing properties, microbiome, and in vitro digestibility barley silages. Barley was ensiled polyethylene drum silos (30 L) with respective densities 600, 650, 700, 750 kg/m3 fresh matter (FM), stored for 60 days. The bacterial communities, fermentation quality, were analy...

Forty-five multiparous and 18 primiparous Holstein cows were fed three levels of crude protein (CP), each at three levels of neutral detergent fiber (NDF), to identify optimal dietary CP and energy. Cows were blocked by parity and days in milk into seven groups of nine and randomly assigned to an incomplete 9 x 9 Latin square trial with four, 4-wk periods. Diets were formulated from alfalfa and...

in this study, the nutritive values of treated walnut hull by neurospora sitophila were evaluated. the chemical composition of samples was evaluated by laboratory analysis.in vitrodigestibility experiment was done to determine digestibility coefficients of dry matter, organic matter and also digestible organic matter in dry matter (domd) to estimate the metabolizable energy (me) content oftreat...

The objective of this study was to determine the effect drought stress on neutral detergent fiber (NDF) and lignin (LIG) concentrations in vitro dry matter digestibility (IVDMD) (IVNDFD) leaf blades stem internodes corn for silage. Eight plots were blocked (i.e., 4 blocks) randomly subjected a watered (W) or non-watered (NW) treatment. Within each block, split into 7 sub-plots, which 1 hybrids ...

Pineapple waste silage (PAS) is an abundant agro-industrial by-product characterized by its high fiber content posing a potential feed value as roughage for ruminants. Studies on supplementation with proteolytic enzyme (PE) will help extend utilization alternative nutritive source cattle nutrition. Thus, this study aimed to determine the in vitro nutrient degradability and fermentation characte...

Good quality and economical availability of fodder could be a substitute for crop production in the farming system dryland areas. In Pakistan, increasing demands crops animal feed require immediate attention to find viable options production. Additionally, climate change, land detritions, imbalanced use chemicals led an agro-ecological imbalance which needs focus on mitigation strategies practi...
