this experiment was conducted in order to determine the effects of different dietary growth promoters on growth performance and nutrient digestibility in male broiler chickens. a total of 360 male broiler chicks (day-old ross 308 strain) were distributed into a completely randomized design (crd) having 6 dietary treatments with four replicates and 15 birds in each replicate. experimental treatm...

the effects of trigonella foenum graecum (tf) and foeniculum vulgare (fv) seeds powder on antimicro-bial activity and performance of broiler chickens were studied. based on a completely randomized design, 240 broiler chicks (ross 308) were assigned to 4 treatments and 4 replicates. the treatments were a basal diet (control, t 1), t 1 plus 0.5% tf (t 2), t 1 plus 0.5% fv (t 3) and tffv (0.25% tf...

this research was conducted to evaluate the effects of adding five levels of ferula assa foetida powder (0, 0.25, 0.50, 0.75 and 1 percent of diet) on performance, humoral and cellular immune status and cecal microbial population. a total of 200 one-day-old mixed sex ross 308 broiler chicks were randomly assigned to 5 experimental groups with each four replicates and 10 birds in each replicate,...

three hundred and sixty male day- old ross 308 broiler chicks were randomly assigned to four dietary treatments in order to evaluate the effect of propolis as growth promoter on the performance and the immune response of the broiler chicks to the nd vaccine. each treatment contained three replicates of 30 chicks. dietary treatments were as follow: a corn - soy meal diet (control diet).control d...

In order to study effects of nitrogen fertilization and cultivars on some of traits of different barley an experiment was conducted at Isfahan in 2012. The experimental was split plot in a randomized complete block design with three replications. In this experiment, different levels of nitrogen in the main plots included four levels (0, 50, 100 and 150 N kg/ha (urea)) and barley cultivars inclu...

Objective: An experiment was conducted to investigate the effects of citrus brown snail powder as a source of calcium on growth performance, tibia characteristics, immune response and blood metabolites in broiler chickens.  Methods: One hundred and eighty 1-day old chicks were randomly distributed into four treatments, each of which had three replicates. Each replicate contains 15 chicks. The t...

This study was conducted to determine the effects of adding ethanol extract of propolis (EEP) and cumin essential oil (CEO) to diets of broiler chicks on the performance, blood parameters, immune response and carcass traits. A total of 240 day-old Ross-308 broiler chicks were randomly allocated to four treatments with six replicates and 10 birds in each replicate in a completely randomized desi...

thirty six male chall lambs (four-month old and 26  ±1.5 kg body weight) were randomly assigned into four treatments (nine lambs per treatment) to study the effect of powerfeed® (a commercial mixture made from wheat processing by-product and wheat bran) on weight gain, feed intake, feed conversion ratio, serum sodium and potassium concentration and urine ph. lambs in control group were fed with...
