abstract poultry manure contains considerable nutrients and its application to agricultural land may boost soil fertility. in order to study the effects of poultry manure and its incorporation method with soil on soil chemical properties, a field experiment was conducted at the ecological research center of zagroos, 30 kms from northeastern of khorramabad for two consecutive years (2004 and 200...

In this trial effects of feeding pistachio by-product silage with date waste (PBSD) on dry matter intake (DMI), live weight gain and blood parameters of lambs were studied. Ensiling of pistachio by-products (PBP) with date waste increased dry matter (DM) and metabolizable energy (ME), but decreased the percentages of crude protein (CP), total tannins and phenolic compounds (P

in this study, the chemical composition of the tea wastes determined. the value of dry matter, organic matter, crude protein, crude fiber, calcium and phosphorous 95, 94, 13.3, 23.1, 0.011 and 0.29 percent, respectively. in the experiment of digestibility by animal, five experimental rations (including tea waste and alfalfa in the proportion of 0:100, 10:90, 20:80, 25:75 and 30:70 percent) and ...

An experiment was conducted to study the effects of lamtoro (Leucaena leucocephala) leaf supplementation in fermented kumpai grass (Hymenachne amplexia calis) based rations on the productivity of Bali cattle. Variables measured were dry matter and organic matter intakes, nutrient digestibility (dry matter, organic matter, crude protein, and crude fiber), body weight gain, and feed efficiency. T...

This study evaluated the effects of seven biochar products at two levels inclusion [2.25% or 4.50% diet dry matter (DM)] on DM disappearance (DMD), cumulative gas and methane (CH 4 ) production, ammonia-nitrogen, volatile fatty acid (VFA) production from Timothy grass hay over 48 h incubation. Biochar did not affect CH (P ≥ 0.17) nor DMD ruminal fermentation 0.12). In conclusion, biochar, irres...

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 ...

this study was conducted to investigate the effect of biological treatment withpleurotus floridafungi on chemical composition and rumen dry matter (dm) and organic matter (om) degradability of wheat and barley straw. wheat and barley straw were collected from golestan province of iran and after pasteurization mixed with fungi spawn (than 5% by weight). after 21 days samples were dried in oven (...

Miscanthus× giganteus, a perennial rhizomatous grass commercially used as a biofuel crop was grown in a field experiment on a silty clay loam soil for 14 years. There were 3 rates of fertilizer nitrogen (N), none (control), 60 kgNha−1 yr−1 and 120kgNha−1 yr−1 as cumulative applications. The crop was harvested in winter and dry matter yield measured. N did not influence yield. Yield, which incre...

Water-use efficiency and stable isotope composition were studied in three tropical tree species. Seedlings of Tectona grandis, Swietenia macrophylla and Platymiscium pinnatum were grown at either high or low water supply, and with or without added fertilizer. These three species previously exhibited low, intermediate and high whole-plant water-use efficiency (TE) when grown at high water supply...
