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...
The experiment was conducted to evaluate the effect of antibiotic, organic acid, probiotic and prebiotic on performance and small intestinal morphology in male Ross 308 broiler chicks for 42 days in tropical conditions. The study was completely randomized design with 5 treatments, 4 replicates and 8 chicks per each. The treatments were: T1: basal diet, T2: diet containing antibiotic oxytetracyc...
The present study was performed to investigate the effects of dietary organic and inorganic selenium on the quality of frozen-thawed semen of broiler breeder cockerel under oxidative stress. In this experiment, a total of 24, 28-week-old Ross 308 cockerels were allocated into 4 treatments each of which had 6 birds, in a completely randomized design. Experimental groups were: 1) control group (C...
The aim of this study was to investigate the effect of different levels of aflatoxin on the gas production, in vitro fermentation parameters, dry matter and organic matter digestibility of sheep's diet. This experiment was conducted in a completely randomized design with 5 treatments and 4 replicate per treatment. The treatments included 1.diet without aflatoxin and methanol (control), 2.c...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
The present study was conducted to evaluate the efficacy of organic acids combination on performance, blood biochemical parameters, intestinal morphology and internal egg quality parameters of layer Japanese quails in completely randomized design manner using 225 layer quails in 3 treatments, 5 replicates and 15 quails in each replicate, reared for two periods of 3 weeks each (37-39 and 40-42 w...
Organic production and consumption provide a delineated food system that can be explored for its potential contribution to sustainable diets. While organic agriculture improves the sustainability performance on the production side, critical reflections are made on how organic consumption patterns, understood as the practice of people consuming significant amounts of organic produce, may also be...
Nowadays silver nanoparticles are being considered as an alternative to antibiotics. Silver is one of the most important elements in nanotechnology due to extensive antibacterial activity. The aim of present experiment was to evaluate the effect of silver nanoparticles coated on zeolite and organic acids on performance, intestinal morphology, gastrointestinal microbial population and carcass ch...
The aim of the present study was to find out whether the incorporation of organic dairy and meat products in the maternal diet affects the contents of the conjugated linoleic acid isomers (CLA) and trans-vaccenic acid (TVA) in human breast milk. To this purpose, milk samples from 312 breastfeeding mothers participating in the KOALA Birth Cohort Study have been analysed. The participants had doc...
The aim of this study was to evaluate the effect of different levels of organic and mineral sources of selenium on the intestinal morphology and also histologically changes in liver tissues of juvenile rainbow trout for 60 days. For this purpose, 1080 healthy fry fish (50±2.8 g average body weight) were randomly divided into 3 groups, including organic selenium (0.15, 0.30, 0.45, 0.60 mg. kg-1)...
