The purpose was to evaluate the effect of extruded roughage Foragge® with different additives on intake, digestibility nutrients and nitrogen balance sheep. Twenty adults, non-pregnant ewes average weight 68 kg were used. treatments (essential oil, virginiamycin, unpurified inactive yeast, tannin purified yeast). design in randomized blocks. means contrasted by SNK test, fecal score tested Krus...

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...

The near-infrared spectroscopy (NIRS) combined with modified partial least squares (modified PLS) regression was used for determining the neutral detergent fiber (NDF) and acid (ADF) fractions of chickpea (Cicer arietinum L.) seed. Fifty accessions (24 desi 26 kabuli types) fifty recombinant inbred lines F5:6 derived from a × cross were evaluated NDF ADF, scanned by NIRS. ADF values regressed a...

The effect of inclusion of garlic essential oil (EO) at 33, 66 and 100 µg mL(-1), raw garlic (GAR) at 5, 10 and 15 mg mL(-1) and monensin (MON) at 7.5 µg mL(-1) of incubation medium on organic matter digestibility (OMD) was studied with in vitro gas production, ANKOM daisy(II) and conventional in vitro (IVOMD) methods. The material was incubated with sheep ruminal fluid and the experimental des...

Supplementation of dairy rations with steroidal sapogenins was evaluated in an in vitro, an in situ, and a production trial. Sixteen in vitro semicontinuous rumen cultures were supplied a 55:45 concentrate to roughage substrate with Sarsaponin concentrations of 0, 33, 55, and 77 ppm of air-dry feed for 22 d. Supplementation decreased protozoa numbers and increased bacterial numbers and acid det...

The purpose of this study was to determine the effect of rumen inoculum from heifers with fast vs. slow rate of in situ fiber digestion on the fermentation of complex versus easily digested fiber sources in the forms of untreated and Ammonia Fiber Expansion (AFEX) treated barley straw, respectively, using an artificial rumen simulation technique (Rusitec). In situ fiber digestion was measured i...

Thirty five growing male goats (6.98±0.86 kg BW) were divided into five equal groups with seven animals in each group. The five dietary treatments were consisted of varying proportions of Moringa foliage (Moringa oleifera) and napier grass (Pennisetum purpurium); T1 (100% Moringa foliage); T2 (75% Moringa foliage+25% napier grass); T3 (50% Moringa foliage+50% napier grass); T4 (25% Moringa foli...

Two experiments using six rumen-fistulated Holstein steers in 3 X 3 Latin square designs were conducted to test the effects of urea addition to corn silage, and grain addition to haylage, on feed intake, digestibility of nutrients and rumen fermentation of complete diets fed once daily. Addition of .34 and .68% urea to corn silage increased dietary crude protein from 8.1 to 11.3 and 13.3%, and ...
