Many feed and forages are exposed to low, medium or high levels of organophosphorous (OP) pesticides. It is unclear whether these exposures (for example diazinon as an OP pesticide) impact dry matter degradability parameters. So, different levels (0, 0.7, 2.8 and 5.6 mg) of diazinon as an OP pesticide with different levels of calcium bentonite (CB) (0 and 100 mg) as a toxin binder were tested f...

The chemical composition, degradability coefficients (in situ) and ruminal-intestinal disappearance(mobile bag procedure) of dry matter (DM) and crude protein (CP) were evaluated for olive cake (OC)silages treated (DM basis) with additives as follows: (1) untreated OC, (2) OC + 0.5% urea, (3) OC + 0.4%formic acid, (4) OC + 8% molasses, (5) OC + 0.5% urea + 8% molasses, (6) OC + 0.5% urea + 0.4%...

The objective of the present study was to evaluate effects of in vitro rumen solubility or degradability of dietary protein on net absorption of nitrogenous compounds from portal-drained viscera of beef heifers. Four protein sources, casein, soya-bean meal, maize-gluten meal and blood meal provided about two-thirds of total dietary nitrogen in semi-purified diets given to four beef heifers in a...

The objectives of this study were to determine the molecular weight of condensed tannins (CT) extracted from mangosteen (Garcinia mangostana L) peel, its protein binding affinity and effects on fermentation parameters including total gas, methane (CH4) and volatile fatty acids (VFA) production. The average molecular weight (Mw) of the purified CT was 2,081 Da with a protein binding affinity of ...

Protein and energy are the two major components of feed that influence performance of the growing and fattening lambs. Provision of the quality of protein in the lamb’s diet does not only improve the animal performance but also ensures profitable animal production. Different vegetable protein sources are used to formulate the rations for growing and fattening lambs. These protein sources differ...

The objectives of this study were to determine an optimal cultivation time for populations of yeast and lactic acid bacteria (LAB) co-cultured in fermented milk and effects of soybean meal fermented milk (SBMFM) supplementation on rumen degradability in beef cattle using nylon bag technique. The study on an optimal cultivation time for yeast and LAB growth in fermented milk was determined at 0,...

Seven cannulated (rumen and duodenal) Angus x Hereford steers (264 +/- 8 kg BW) consuming low-quality forage (5% CP; 61% NDF; 31% ADF) were used to determine the influence of CP degradability and supplementation frequency (SF) on DMI and nutrient digestion. Treatments included an unsupplemented control and degradable intake protein (DIP) or undegradable intake protein (UIP) provided daily, ever...
