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...

this experiment was conducted to determine the effects of myrtle essential oil (meo) on growth performance, carcass characteristics, antibody titer and blood parameters of broiler chickens. a total of 200 ross 308 broiler chickens were allocated to five dietary treatments with four replicates of 10 birds each. dietary treatments were prepared by formulating a corn-soybean meal-based diet free o...

this study was conducted to investigate the effects of dietary nigella sativa meal (nsm) on the growth performance, blood parameters, carcass characteristics, egg yolk cholesterol and meat quality in japanese quail. for this purpose 300 one-day old japanese quail chicks in a completely randomized design was used with five treatments in four replicates )containing 15 birds each(. the experimenta...

this experiment was conducted to investigate the effects of using protexin, propionic acid growth promoters, and a blend of them on broilers performance. in a completely randomized design, three hundreds and twenty unsexed 1-d-old chicks were divided into four groups. dietary treatments were consisted of 1) control diet without any supplement, 2) the control diet + 0.01 % protexin, 3) the contr...

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...

The aim of this study was to determine whether the age of broilers can influence their response to tannin-rich diets. A total of 340 one-day-old mixed sex Ross 308 broiler chicks were distributed among five experimental groups with four replicates and 17 birds each in a completely randomized design. A high-tannin feedstuff, Oak acorn, was included into diets (at a level of 25%) and fed to birds...
