The aim of this study was to evaluate the effects of copper (Cu) sulfate (0, 125 and 250 mg/kg), arginine (Arg) supplements (0, 0.1 and 0.2%) and glucosinolate content on performance and carcass traits in broiler chickens fed with canola meal based diet. During a three-week experimental period (22-42 d), 405 male broilers were used in completely randomized design with a 3 × 3 factorial experime...

objective: this study was conducted to evaluate the effects of different proportions of marshmallow extract (althaea officinalis l.) on growth performance and carcass composition of common carp (cyprinus carpio). methods: common carp with an average weight of 37.65 ± 4.40 g were fed for two months with a diet supplemented with marshmallow (a. officinalis) extract 0.25%, 0.50 and 1%, and with no...

in order to investigate the effect of processing type (whole straw bale processing or opened straw bale processing with urea) on diet digestibility, economical and productive parameters in feedlot cattle, 18 holstein bull with average body weight 224.72 ± 20.45 kg were used in a completely randomized design with 3 treatments and 6 replicate. treatments 1, 2 and 3 contained 40% typical straw, 40...

the aim of this study was to evaluate the effects of three lighting programs on immune system and performance of broiler chickens. a total of 288 seven day-old male broiler chicks (ross-308) were randomly distributed between three treatments. each group was housed in the separated room with eight pen and 12-birds per pen. the management conditions were similar for all treatments throughout the ...

the objective of this research was to investigate the efficacy of dietary inclusion of probiotics primalac® and bactocell® and prebiotic fermacto® on broiler’s performance and immune response, individually or in combination. a total of 540 one-d-old male ross 308 broiler chicks were allocated into 6 experimental treatments with 6 replicates of 15 birds per replicate from 1 to 42 d of age. the b...

Abstract Understanding the effects of high- and low-fiber diets on growth performance pigs with different feed efficiencies will help livestock industry develop new strategies to reduce costs pig production. In this study, 18 Landrace × Large White sows high low estimated breeding value conversion ratio (EBV-FCR) were inseminated semen from known EBV-FCR produce 9 litters efficiency pigs. A tot...
