abstract. information on forage quality in phenological stage could help range managers to choose suitable grazing method to achieve higher animal performance without detriment to vegetation. vetiver grass (vetiveria zizanioides) is a non-native perennial grass that was introduced to the iran in 2008. this plant is a multi use species that could be considered from different viewpoints. thus, it...

intercropping is considered as a method for increasing yield per unit and stability. in order to evaluate the effects of phosphorous biofertilizer and chemical phosphorous on fodder quality of corn (zea mays l.) and grass pea (lathyrus sativa l.) intercropping, two field experiments were conducted as factorial based on randomized complete block design with four replications at two places simult...

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...

A digestibility trial was conducted to examine the effect of feeding rate on dry matter, gross energy, crude protein and phosphorus digestibility in Atlantic salmon (Salmo salar). Duplicate groups of fish were fed 0.25, 0.5, 0.75, 1.0, 1.25 and 1.9% BW/day. The faeces were collected by Guelph-type collectors for five successive days. Dry matter, protein and phosphorus digestibility’s wer...

Supplementation increased the total dry matter intake by 18.2-36.8 %. Supplements given alone or in combination had no effect on dry matter and organic matter digestibility of the diet. Crude protein digestibility was decreased with molasses supplementation. Crude fiber digestibility was not affected by baker’s yeast supplementation but decreased with other supplements. The digestibility of nit...

this study was conducted to determine the chemical composition and degradability characteristics of a pasture plant salsola tomentosa by nylon bags method .the sampling was performed from the northern region of plain's gonabad city in three growth stages (vegetative, flowering and seeding). the samples dried in air, were milled and their chemical composition were determined. to determine the de...

one of the important factors to make a balance between number of grazing livestock and grazing capacity is whether forage contains sufficient energy and protein during grazing period or not. therefore in this study, forage quality was evaluated for important species in steppe rangelands of changuleh located in ilam province. to do this, samples from four species of hammada salicornia, salsola l...
