Aim The purpose of this study was to know the production performance and economic analysis in quail which use probiotic supplementation to alternate antibiotic growth promoter (AGP) to feed consumption, water consumption, egg production, egg mass, feed conversion, and feed efficiency. Materials and Methods About 240 quails (Coturnix coturnix japonica) at 14 weeks of age were completely random...

this experiment was conducted to compare the effects of prebiotic as alternative feed additive to an antibiotic growth promoter (bacitracin methylene disalicyate) on the growth performance and morphometrical parameters of the small intestine of broiler chickens. one hundred and forty four day old broiler chicks were randomly assigned to one of three dietary treatments for 6 wk and each treatmen...

The objective was to establish effects of feed presentation time and dietary forage to concentrate ratio on circadian postprandial rhythms of feed intake in lactating cows. Four multiparous and four primiparous Holstein cows were fed in a 4 × 4 Latin square design (with a 2 × 2 factorial arrangement of treatments) a higher (HC, forage to concentrate ratio = 38.5:61.5) or a lower (LC, forage to ...

During haymaking and ensilage, a significant loss of sugars occurs. The addition total mixed ratio (TMR) with liquid feed might provide promptly utilisable energy recover the nutrients lost during conservation. Interesting results were already obtained by including in TMR dairy cow. However, possibility to also utilize them Italian Mediterranean buffalo is not yet supported data. This study aim...

an experiment with 240 one-day-old lohman male broilers was conducted to investigate the effects of different levels of palm kernel meal supplemented diet with/without enzyme on performance and lactic acid bacteria population of ceca. birds were distributed in 20 experimental units and data were analyzed in a complete randomized design with 2x2 arrangement plus a control diet.the levels of palm...

Fatty acid esterification is increasingly realized as a reactive distillation (RD) process because of its formation being affected by the chemical equilibrium. The reactive distillation column performance for the production of isopropyl palmitate by esterification of the palmitic acid with isopropanol has been studied in the present research. The reaction was catalyzed in the presence of zinc a...

soil conservation is one of the most important regulative functions of natural ecosystems. this function is of high importance in taleghan watershed due to high erosion quantity and sediment accumulation in taleghan dam reservoir. soil loss reduction, sedimentation control and fertility conservation were considered as different aspects of soil conservation. effect of land use and vegetation cov...

in this study, the effects of culban seed (vicia peregrine l.) on live body weight, feed intake, feed efficiency, egg production, egg quality characteristics, egg yolk fatty acid profiles and yolk cholesterol content in laying hens were investigated. the experiment consists of seven treatment groups with ten replications containing one laying hen in each and for 32 weeks old seventy laying hen ...
