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...

Two studies were conducted utilizing 270 chickens to evaluate the efficacy of yeast culture (YC) for both broiler and layer ayian types. In the first experiment, three dietary levels (0, 1.25, 2.50 percent) of YC were included in a nutritionally complete ration and fed to 14-day-old broiler chicks for 8 days. Body weight gain, feed consumption (g) and feed efficiency were not influenced by yeas...

T HREE switchback metabolism studies were conducted to study the effects of replacing corn with 5, 10 and 15% cane molasses. Five percent molasses had no significant effect on any of the parameters studied. At 10 and 15% molasses added at the expense of corn in the basal ration, nitrogen retention and apparent digestibility of dry matter and energy were all significantly improved (P< .05) . The...

The influence of corn silage feeding level was examined on eighty-three Charolais crossbred steers (389+30 kg BW). Each steer was randomly assigned to one of four diets which contained either 0, 15, 50 or 85 percent corn silage (CS) dry matter. Each ration was balanced to a 13.6 percent crude protein level. Mineral, vitamin and ionophore fortifications (monensin @ 33 ppm) were similar for each ...

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

the objectives were to investigate the effects of addition of alfalfa hay as an absorbent on fermentationquality and effluent production of corn silage. three levels of corn forage with dry matter (dm) contentsof 18.3, 21.7 and 25.5 percent were supplemented with 0, 5, 10, and 20 percent alfalfa hay, on as fedbasis, and ensiled in three replicates in polyvinyl chloride mini-silos in a completel...

this research was carried on to evaluate the response of rapeseed varieties to salt stress. in this experiment growth response of three rapeseed varieties (fornex, consoul and okamer) in four salinity levels (0, 40, 80 and 120 mmol nacl) was investigated using a factorial arrangement of factors in a complete randomized block design with three replications. results incicated that in the highest ...

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...

Future galaxy surveys require one percent precision in the theoretical knowledge of the power spectrum over a large range including very nonlinear scales. While this level of accuracy is easily obtained in the linear regime with perturbation theory, it represents a serious challenge for small scales where numerical simulations are required. In this paper we quantify the precision of present-day...

the objective of this study was to evaluate the effects of sources of four starch on milk production and composition, nutrients digestibility and blood metabolites of lactating holstein cows. eight multiparous holstein cows (683±31 kg of body weight; 83±9 dim) were used in a replicated 4×4 latin square design with 21-d periods. the exprimental diets contained wheat, barley, corn, or potato as t...
