The current study was conducted to evaluate effects of sequential or wet feeding programs subsequent to and early meal feeding regime on performance, carcass characteristics and humoral immunity in broiler chicks. 192 Ross 308 chicks (seven-day old) were allocated to four treatments at four replicates (12 chicks per plot) based on a Completely Randomized Design. Treatments were included: contro...
This experiment was conducted to determinate the effects of different levels of Amet protein binder (0, 1.5, 3, 4.5 and 6) in substitution for fish meal on performance and digestibility of nutrients. This study used 400 broiler chickens (Ross strain) with 5 treatments of 4 replications in a completely randomized design. Weight gain, feed consumption, and feed conversion ratio were determined at...
campylobacter is known to be one of the most common causes of human intestinal disorders. since poultry are known to be the main reservoirs for this pathogen, decreasing this bacterium in intestinal tract could be beneficial in reducing contamination of poultry products. the effects of probiotic (primalac®), medicinal plant (sangrovit®) and organic acid (selko-ph®) as broiler feed additives on ...
six hundred day old unsexed broiler chicks were used in a 42-d trial at chittagong veterinary and animal science university poultry farm to compare the effects of different levels of fish oil supplementation on performance of broilers in terms of feed intake, weight gain and feed conversion and carcass characteristics. the chicks were randomly distributed following a completely randomized desig...
six hundred day old unsexed broiler chicks were used in a 35-day trial to compare the effects of soybean oil, palm oil and fish oil supplementation on the performance of broilers in terms of feed intake, weight gain and feed conversion. the chicks were randomly distributed following a completely randomized design in four groups having three replications per treatment. each treatment had 150 bir...

This study was carried out to investigate the effects of Savory essential oil and Flavomycin on performance, some carcass traits, immune response and hematology of broiler chickens. In this research, four houndered Ross 308 male chicks were used in a completely randomized design with 5 treatments and 4 replicates and 20 broiler chicks per experimental unit. Experimental treatments consisted of ...
This study was conducted to compare the feedlot performance and growth traits of Lori-Bakhtiari (n=39), Romanov × Lori-Bakhtiari (n=38) and Pakistani × Lori-Bakhtiari crossbred (n=12) lambs during two consecutive years. Lambs were weaned at the age of 90 ± 5 days. After weaning and preliminary fattening period, three groups of lambs were fattened for 90 days in the same conditions. The resul...
The effect of energy and protein dilution in the starter period (8 to 14 days) of age, on performance and carcass characteristics of 360 Arian male chicks was studied in a completely randomised design. This experiment consisted of 6 treatments, 4 replicates, with 15 chicks per replicate. In order to dilute the diets six levels (0, 4, 8, 12, 16, and 20) percent of ground wood charcoal was used. ...
two experiments were conducted to investigate the feeding value of waste fig along with its effect on broilers, performance. in the first experiment, the amen content of fig was determined through total collection method using 10 adult leghorn cockerels. in the second experiment, 240 day-old male ross broiler chicks were randomly alloted to 6 experimental groups of 4 replicates of 10 chicks eac...
