an experiment was conducted to evaluate the effects of high dietary levels of selenium (as sodium selenite) and copper (as copper sulphate) on growth performance, serum biochemical parameters and antibody production against newcastle disease vaccine (ndv) virus in broiler chickens. a total of 160 ross 308 unsexed day old broiler chickens were randomly allocated into four treatment groups (n=40 ...

The present study examined the antioxidant defense of glutamine on plasma and liver antioxidant status in broilers under PHS with respect to changes in the levels of lipid peroxidation marker malondialdehyde (MDA), total antioxidant status (TAS) and the activities of anti peroxidative enzymes [superoxide dismutase (SOD) and glutathione dependent antioxidant enzymes glutathione peroxidase (GPX)]...

A total of 160 Ross 308 unsexed day old broiler chickens were randomly allocated into four treatment groups (n=40 ...

the effects of different levels (0, 10, 20 and 30 percentage of dry matter) of apple pomace ensiled with urea were investigated on 24 ghezel male lambs in a completely randomized design with four treatments and six replicates. the average starting weight and age of the lambs were 31.27 ± 7.40 and 187 ± 37 days, respectively. after 15 days of adaptation, the lambs were individually fed with expe...

The objective of this study was to investigate the effects of three levels of threonine (100, 95 and 90% of NRC requirements) with or without of multi strains probiotic (Primalac) on performance, carcass characteristics and blood metabolites of Japanese quails. A total of 180 one-day-old male Japanese quails were randomly allocated to six treatments with three replicates and 10 birds per each. ...

the objective of this study was to investigate the effects of three levels of threonine (100, 95 and 90% of nrc requirements) with or without of multi strains probiotic (primalac) on performance, carcass characteristics and blood metabolites of japanese quails. a total of 180 one-day-old male japanese quails were randomly allocated to six treatments with three replicates and 10 birds per each. ...

background: previous research has shown that cr is needed for growth and protein synthesis. objectives:  this study was carried out to determine the effects of supplementing chromium-methionine (cr-met) on performance, hematologic characteristics and meat quality parameters in kids. methods: thirty-two male kids (average initial bw of 22 ± 2 kg, 4mo) were used in a completely randomized design ...

this experiment was carried out to evaluate the effect of different levels guar meal and β-mannanase on broilers male chicken. in this experiment , four hundred ross day old broiler chicks were randomly assigned to a 4×2 factorial design to feed broiler chickens diets containing guar meal at 4 level of guar meal (0, 3, 6 and 9%) with five replications of each treatment with or without β-mannana...
