effect of l-carnitine and butyric acid on the performance and immune responses of 192 broiler chickens (ross 308) was investigated with three levels of l-carnitine (zero, 125 and 250 mg/kg) and two levels of butyric acid (2 g/kg) in a 2×3 factorial arrangement based on randomized complete block design with 6 dietary treatments, four replicates and eight birds per each. broilers fed basal diet p...

to consider the effect of probiotic and organic acids on performance, carcass characteristics, blood parameters and immune response of broilers, a completely randomized design test was done with four treatments and four replicate for each reatment. two hundred and forty one day-old mixed sex broilers (ross breed) were divided into four treatments with 15 chicks per each replicate (pen). treatme...

We determined the effects of dietary supplementation of different doses of Miswak (Salvadorapersica) steam and leaf powder on the performance, blood parameters, cecal flora, and carcass traits of broilers. Four hundred and eight one-day old Ross 308 broiler chicks were provided one of the following experimental diets over 42 days:  a basal diet without any additives, or a basal diet supplemente...

a total of 160 day-old male broiler chickens (ross 308) were divided in a completely randomized design experiment, and assigned to 8 treatments and 4 replicates in their experimental units (cages). treatments included: t1: basal diet with no additional methionine, t2: basal diet plus 0.06, t3: basal diet plus 0.11, t4: basal diet plus 0.17 % of dl-methionine, t5: basal diet plus 0.06, t6: basal...

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...

A 42-d trial was conducted to compare the effects of probiotic, prebiotic and synbiotic supplements on growth performance, morphology of the jejunum, serum lipid profile and antibody response of broiler chickens. A total of 400 one-d-old male broiler chicks were randomly divided into four treatment groups of four replicates (25 birds per replicate) and fed corn-soybean meal diets. The dietary t...

A feeding trial was conducted to investigate the efficacy of Pediococcus acidlactici (Bactocell®) or Baccillus cereus (Toyocerin®)-based probiotics on turkey’s performance, carcass yield, blood parameters and intestinal morphology. A total of 240 1- day-old male Nicholas turkey poults were allocated into three dietary groups with four replicates. A corn-soybean-based diet was used as a basal di...
