this experiment was conducted to investigate the effect of antibiotic, organic acid, probiotic and prebiotic on quality traits of eggs, egg yolk lipids and blood metabolites of laying hens strain hy-line (w-36). the experiment was carried out as a completely randomized design from 32 to 42 weeks of age with 5 treatments, 4 replicates and 8 hens in each replicate. the experimental treatments con...

a study was carried out to investigate the effects of organic acid mixture as well as two methionine supplements on performance, carcass characteristics and weight of gastrointestinal tract in broiler chickens. six hundred unsexed day-old ross 308 broiler chicks were utilized in a factorial arrangement of treatments (3×2) based on completely randomized design (crd) of 4 replicates of 25 chicks ...

the present experiment was carried out to determine the effects of  antibiotic  growth promoters, blend of medicinal plants, prebiotic and organic acid on performance and nutrients apparent digestibility in a six week period, using one hundred ninety two one- day- old broiler chicks (cobb 500) on a randomized complete block design experiment with six treatments consisting of 4 replications and ...

Objective:  In addition to the role of organic matter in plant nutrition, this material improves soil quality, physical structure, ventilation and water supply, and ease of penetration and expansion is rooted deep in the soil surface. Effects of organic matter due to climatic factors, soil characteristics may vary from region to region, resulting in organic materials management must be given to...

As a contribution to the debate on the comparison of nutritional quality between conventional versus organic products, the present study would like to provide new results on this issue specifically on dairy products by integrating the last 3 years' studies using a meta-analysis approach with Hedges' d effect size method. The current meta-analysis shows that organic dairy products contain signif...

mass generation of bagasse wastes from every 100 kg of sago starch pith being processed are likely to pollute the water when they are discarded into rivers. the increase of livestock production increases manure production and improper management of these manures will pollute the soil and environment, and causing diseases outbreak. co-composting of sago bagasse and chicken manure could serve as ...
