An experiment was conducted on broiler chickens to study the effects of conjugated linoleic acid (CLA), fish oil, both at 7% of the diet, or their mixtures at 3.5% of the diet, on the performance, carcass traits and intestinal morphology of broiler chickens. The chicks fed with 7% fish oil or 7% CLA diets, were found to have an inferior weight gain in grower and finisher phases, respectively. A...

A probiotic containing Bacillus mesentericus, Clostridium butyricum, and Streptococcus faecalis [AVITEAM] was evaluated in damage control and synergism with vaccination against coccidial infection in broilers, using morphometric measurements and histopathological observations. It was mixed in feeds and vaccination was done by inoculating birds with an attenuated live vaccine containing Eimeria ...

to investigate the effect of cinnamon, turmeric and carnation powders on growth performance, carcass characteristics, morphological and ph changes of intestine and blood serum oxidation status in broilers, 450 unsexed ross 308 day-old broiler chicks were randomly allotted in a completely randomized design with six treatments, five replicates and 15 birds per each replicate, for 42 days. the bro...

introduction corn and wheat are the grains most routinely used in commercial poultry diets. for consumption of these cereals, there are a competition between humans and mono-gastric animals. due to corn crop limitation in iran, approximately 50% of the corn required for poultry nutrition is supplied through imports. since triticale is more resistant to various diseases, dry weather and in simil...

The study was conducted to investigate the effects of different levels of xylanase on performance, blood parameters, intestinal morphology, microflora and digestive enzyme activities of broilers. The wheat-based diets were supplemented with 0, 500, 1,000, 5,000 U/kg xylanase. Xylanase supplementation significantly (p<0.05) improved the feed:gain ratio of broilers from 1 to 21 d and 1 to 42 d. S...

The effects of phytase and tannase enzyme treatment sorghum-based broiler diets on ileal villi characteristics were evaluated in Cobb 500 broilers. A total three sorghum levels, 0, 50, 100%, with 4 levels; 5% phytase, phytase+tannase combination used to develop 12 different dietary treatments. Three hundred sixty broilers randomly allocated the treatments a completely randomized design experime...

In the present study, chicory root powder (CRP) as growth promoter at 1% and 3% levels was supplemented in broilers’ diet to investigate the growth performance and histo-morphometry of jejunum. One hundred twenty, one-day-old male broilers were used in a completely randomized design (CRD) with 3 treatments and 4 replicates (10 chicks per replicate). At the end of each period (0-10, 11-...
