this study was conducted to evaluate the effect of electron beam irradiation at doses of 250 and 500 kgy on the chemical composition and ruminal dry matter (dm) and neutral detergent fiber (ndf) degradability of wheat straw. nylon bags of untreated or irradiated wheat straw were suspended in the rumen of three rams for up to 72 h, and resulting data were fitted to non-linear degradation model t...

Intraspecific competition is one of the major factors that can have an effect on the resources utilized within a habitat. Differences in diet quality of selected forage have been noted in size-dimorphic ungulates. However, on an intraspecific basis, data demonstrating a body size influence on diet quality are lacking. We examined diet quality across a range of body masses (14–76 kg) in white-ta...

The objectives of this study were to determine and compare the chemical composition and ruminal degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) of ten pasture forage species dominant in the west provinces of Iran. Duplicate nylon bags of pasture samples were suspended in the rumen of four wethers for up to 96 h. The chemical com...

Published data on the effects of essential oils (EO) on in vivo nutrient digestibility in sheep are contradictory. In 2 experiments, the effect of thymol and carvacrol on nutrient digestibility was studied in sheep fed with high (70%) or low (52%) concentrate diets, using incomplete Latin Square designs. The essential oils were mixed with the concentrate portion of the diet at the rate of 0.0, ...

A study was conducted in a completely randomized design to evaluate the effect of diets formulated on the basis of four critical essential amino acids (lysine, methionine, tryptophan and threonine) on the crude protein requirement, carcass quality, nutrient digestibility, haematological and blood biochemical indices of broiler finisher chickens (28-56 days) reared under tropical environment. On...

Sorghum/millet-based beverages, Obiolor and Pito, were evaluated for their nutritional and antioxidant dispositions. Analyzed Obiolor and Pito contained 96% and 97% moisture; 7.8% and 3.7% crude protein; 8.9% and 5.6% available carbohydrate; 0.39% and 0.31% crude fat; 0.3% and 0.2% crude fiber; 2.4% and 1.5% ash; and 459.3 and 164 kJ/g energy value, respectively. Obiolor and Pito (1.0 mL) scave...

phytate in poultry rations containing rice bran (rb) critically reduce poultry performance while increasing n and p excretion. the objective of this study was to determine whether the anti-nutritive problems associated with higher inclusions of rice bran in poultry rations (up to 40%) could be mitigated with mega doses of phytase. twenty days old male broiler chicks (n=180) in 60 floor pens wer...

The aim of this study was to determine the chemical composition and in vitro digestibility, and to estimate the in vitro fermentation parameters of palm leaves and pedicels from Ghars palm variety. A rumen in situ technique was also used to examine In vitro Digestible Dry Matter (IDDM), In vitro Digestible Crude Protein (IDCP), and In vitro Digestible Neutral Fiber (IDNF), and rate and extent o...

this study was conducted to determine the nutritive value of fresh and ensiled whole and partly stoned olive cake (oc) with or without molasses i.e., 0 and 50 gkg-1 on fresh basis. dry matter (dm), organic matter (om), crude protein (cp), neutral detergent fiber (ndf), acid detergent fiber (adf), lignin (sa), ether extract (ee), water soluble carbohydrates (wsc), and total phenols (tph) of all ...
