this experiment was carried out to investigate the effect of adaptation period to oak leave's tannin on rumen ph and ammonia, rumen microbial population, gas production and dry matter true digestibility (ivtdmd) in alamout goat’s rumen (with no previous history of oak leaf consumption) compared with markhoz goat (with previous history of oak leaf consumption). the goats were fed either oak...

Selenium is an essential element for humans, animals and some species of microorganisms. In higher plants, however, the role of selenium is still unclear. Because selenium enrichment may influence the nutrient balance of plants, a study was done to test the effects of selenite-Se (Na2SeO3⋅5H2O) on selected macronutrients content in maize (Zea mays L. var. saccharata Kcke. cv. Z3ota Kar3owa) see...

in this experiment, fermentation parameters of a tmr ration determined with different levels of phosalone as an organophosphate pesticide (0, 100, 250, 500, 750 and 1000 ppm) and bentonite (0, 1 and 2 %dm of tmr) using in vitro batch culture and gas production techniques. the results from gas production showed that cumulative gas production for 96h after incubation significantly decreased with ...

the aim of this study was to evaluate the effects of feeding pistachio hull (ph) as a source of tannin and polyethylene glycol (peg) supplementation on feed intake, nutrients digestibility, milk yield and compositions, blood lipid metabolits and milk fatty acids profile in saanen dairy goats. nine maltiparus saanen dairy goats were used in a 3 × 3 replicated latin square design with 21-d period...

Khorvash, M., Colombatto, D., Beauchemin, K. A., Ghorbani, G. R. and Samei, A. 2006. Use of absorbants and inoculants to enhance the quality of corn silage. Can. J. Anim. Sci. 86: 97–107. This study examined whether inoculants and various absorbent materials could be used during ensiling to reduce effluent losses and improve nutritive value of corn silage. Two corn forages were harvested: conve...

In humans and rodents, dietary hydroxyproline (hyp) and oxalate intake affect urinary oxalate (Uox) excretion. Whether Uox excretion occurs in cats was tested by feeding diets containing low oxalate (13 mg/100 g DM) with high (Hhyp-Lox), moderate (Mhyp-Lox), and low hyp (Lhyp-Lox) concentrations (3.8, 2.0, and 0.2 g/100 g DM, respectively) and low hyp with high oxalate (93 mg/100 g DM; Lhyp-Hox...

the aim of this study was to evaluate the effects of chemical treatments including urea (5%), ammonia (3.5%), calcium hydroxide (4%), sodium hydroxide (5%), sulphuric acid (5%) and hydrogen peroxide (5%) on ph, dm solubility, lignin, silica, phenolic compounds, cellulose and hemicellulose stucture and ruminal degradability of rice straw. after processing, the treated straw was ensiled for 1 mon...

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%...

Salinity is a major abiotic stress for crop production in many parts of the world. To evaluate the effects of irrigation with saline water on growth parameters and forage quality of globe artichoke (Cynara cardunculus var. scolymus), a field experiment was conducted using a randomized complete block design with three replications at Isfahan Agricultural and Natural Resources Research and Educat...
