In vitro techniques were evaluated to determine the nutritive value of a selection of tanniniferous tree and shrub legumes (Calliandra calothyrsus, Leucaena leucocephala L. diversifolia and L. pallida) compared with lucerne (Medicago sativa). Polyethylene glycol (PEG) was also added to some in vitro fermentations (10 mg PEG/50 mg plant substrate) to assess the effects of tannins on digestion of...

Background: Fat supplementation in ruminants ration often adversely affect dry matter intake (DMI), rumen fermentation and nutrients digestion. Basal diet ingredients is an undeniable determinant of ruminants responses including performance, chewing behaviour and nutrient digestibility to fat supplementation. Objective: Current study was conducted to evaluate the effect of Fish oil (FO) supplem...

the effects of a multi enzyme were evaluated on performance and nutrient digestibility in african domesticated ostrich at 14 months ages. there were three treatments as; common diet (1), common diet plus multi enzyme (0.350 gkg -1) (2) and common diet plus multi enzyme (0.700 gkg -1) (3). 18 ostrich were used in this experiment (6 birds per treatment). there was significant effect of enzyme sup...

The nutritive values of non- processed and processed grape pomace with Neurospora sitophila were evaluated. The chemical compositions and physical characteristics of samples were evaluated by laboratory analysis. An in vitro digestibility experiment was done to determine digestibility coefficients of dry matter, organic matter and also digestible organic matter in dry matter (DOMD) to estimate ...

Three corn hybrids (Pioneer 36F30, Mycogen TMF2450, and Mycogen TMF2404) were compared for yield and quality traits, and lactation performance and apparent digestibility by Holstein cows. The three corn silages were harvested at a target of 33 to 35% dry matter. Before harvest, six corn plants were randomly selected for plant fractionation. Grain-to-stover ratios were 0.92, 0.70, and 0.95 for t...

North American porcupines (Erethizon dorsatum) subsist predominantly on low-protein, high-fiber, high-tannin diets. Therefore, we measured the porcupine's ability to digest dry matter, fiber, and protein by conducting digestion trials on eight natural forages and one pelleted ration varying in concentration of fiber, nitrogen, and tannins. On these diets, dry matter intake ranged from 5 to 234 ...

sunflower has many dry forage yields and is richer than corn in inorganic matter, protein and calcium. therefore, use of this forage in livestock diets can be valuable for elimination of food poverty. in order to determine the best harvest stage for sunflower silage, an experiment was conducted in 2007-2008 at agricultural faculty of shahid chamran university of ahvaz. a randomized complete blo...

I . In the first of two experiments four sheep were fed on dried grass and oat straw in the following combinations: ( I ) straw eaten to appetite and an equal quantity given via a rumen fistula, (2) straw eaten and grass by fistula, (3) grass eaten and straw by fistula, (4) grass eaten and grass by fistula. Mean daily dry-matter intakes (g/kg metabolic live weight, W0,75) for the four treatment...

This experiment evaluated different strategies for allocating first-cut grass silages to dry dairy cows that had low body-condition score (BCS) at drying off. A total of 48 moderately yielding Holstein-Friesian cows were used, receiving one of three dietary treatments in the dry period and a single lactation diet based on a flat-rate of concentrates and grass silage ad libitum. Throughout the d...
