Unlike other nutrients, such as protein and calcium, where requirements are provided in grams per cow per day for specific body weight and milk production levels, fiber “requirements” are merely minimum guidelines (NRC, 2001) aimed at maintaining normal ruminal pH, fiber digestion and milk fat test and preventing sub-acute rumen acidosis (SARA), laminitis and displaced abomasums (LDA). NRC (200...

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...

the aim of present experiment was to investigate the feeding value of wild pistachio leaf (khinjuk leaf, kl) for arabi sheep. the digestibility and fermentation of diets containing different amounts of khinjuk (0, 5, 10, 15, 20, 25 and 30%) were measured. then, the effect of presence of kl in the diet and its tannin content on the digestibility of alfalfa hay (alfa), wheat straw (ws) and soybea...

Controlled fermentation of Sweet potato (Ipomoea batatas) var. Beauregard by yeast, Saccharomyces boulardii (MAY 796) to enhance the nutritional value of sweet potato was investigated. An average 8.00 × 1010 Colony Forming Units (CFU)/g of viable cells were obtained over 5-day high-solid fermentation. Yeast cell viability did not change significantly over time at 4°C whereas the number of viabl...

The objective of this study was to determine the effects of garlic oil (Allium sativa), turmeric powder (Curcuma longa Linn) and Monensin on Total apparent digestibility of nutrients in Baloochi lambs. The experiment was designed as a 4 x 4 Latin square using 4 ruminally baloochi lambs with 4 treatments in four 28-d periods. Treatments were control (no additive), garlic oil (0. 4 g/d), monensin...

The objective of this study was to evaluate the best level of inclusion of cactus pear in the ensiling of elephant grass Brazil seeds (BRS) capiaçu (Pennisetum purpureum), its effects on fermentative characteristics; and nutritional value. Experimental treatments consisted of BRS capiaçu grass silage with five levels of inclusion of cactus pear (0, 5, 10, 15 and 20% inclusion as fresh ...

this study was conducted to determine nutritive value of common animal feed sources in east azerbaijan province including second cutting of alfalfa hay ( n=35) and wheat straw (n=26). chemical composition and mineral contents of alfalfa hay and wheat straw were determined according to standard methods. then the average chemical compositions of these samples were compared with those of the gilan...

the effects of replacement of alfalfa hay with pistachio by-product (pb) at 0, 25, 50, and 75% (dm basis) on the ruminal parameters, dry matter intake (dmi) of female rayini goats, after kidding, and on the live weight gain (lwg) of their kids were investigated. five single-bearing female rayini goats each with a single kid were employed in each level of replacement. the basal diet contained ba...

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...

This study was carried out to determine the nutritional value of different chickpea varieties using in vitro gas production technique.As a result, significant variations in terms of chemical composition, gas production rate and metabolizable energy, net lactation energy and digestible organic matter were found among the 8 different chickpea varieties. The crude protein contents of chickpea vari...
