one of the most effective ways to reach yield stability with low input is increasing diversity through utilizing intercrops in agro-ecosystems. a field experiment based on a randomized complete block design with six treatments and three replications and two crops, green pea and nutrifed millet, was carried out at research farm of agriculture and natural resources of kerman during growing season...

The objectives of this study were to evaluate the dynamics of gas production of several corn (co)products, to develop equations to predict the rate of ruminal fiber digestion, to estimate total digestible nutrients (TDN) and net energy for lactation (NE(L)), and to assess the stochasticity of chemical composition and nutritive value variability. Four corn milling (co)products were evaluated in ...

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, ...

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...

Two experiments were conducted with second-parity sows fed either 5 or 50% alfalfa meal diets (Exp. 1) or 5, 50 or 95% alfalfa meal diets (Exp. 2) beginning 30 d after breeding and continuing through lactation, 21 d postpartum. Diets in both experiments were calculated to be equal in crude protein, but different in metabolizable energy content. Feed intake was restricted to 2 kg/d during gestat...

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 daisyII and conventional in vitro (IVOMD) methods. The material was incubated with sheep ruminal fluid and the experimental design was ...
