This experiment was conducted to study the effects of two kinds of sodium and calcium bentonite (NaB and CaB) on performance, blood biochemical parameters, carcass characteristics and tibia ash of broiler chickens. Two hundred and sixty day old broilers of male Ross 308 strain were allocated to 5 treatments with four replicatates and 13 broilers in each. The experiment was carried out in a comp...
watermelon seed full-fat (wmsf) and watermelon seed meal (wmsm) samples were analyzed for proximate composition and then incorporated in broiler chicks diets at increasing levels up to 20%. feeding increasing levels of wmsf to broiler chicks for up to 20% increased weight gain (p
Two experiments were conducted to investigate the effect of dietary energy levels on the performance of Arian broiler chicks. Trial 1 was performed in summer and trial 2 in fall. Both experiments were accomplished in 5×2 factorial designs, involving 5 levels of dietary metabolizable energy and two sexes. Each of the 10 resulting treatments was replicated 4 and 3 times in trials 1 and 2, respect...
The current study was carried out to investigate the effect of dietary inclusion of soybean hull on performance, carcass characteristics and blood parameters of broiler chickens from the age of 1 to 42 days. A total of 240 day-old broiler chickens (Ross 308) which were randomly assigned to 4 dietary treatments with 5 replicates of 12 birds in each replicate. Experimental treatments were control...
the effects of different dietary levels of soybean oil (2, 4 and 6%) and probiotic primalac (0, 0.1 and 0.15 %) were investigated on performance and immune system of broiler chickens from day one to day 42 of age. for this purpose, five hundred and forty day-old male broiler chicks (cobb) in 9 groups of 60 each were used. the birds of each group were divided into 6 pens of 10 birds. the experim...

this experiment was conducted to study the effects of two kinds of sodium and calcium bentonite (nab and cab) on performance, blood biochemical parameters, carcass characteristics and tibia ash of broiler chickens. two hundred and sixty day old broilers of male ross 308 strain were allocated to 5 treatments with four replicatates and 13 broilers in each. the experiment was carried out in a comp...
this experiment was conducted to evaluate the effect of different levels of crude protein and threonine on performance, carcass characteristics and immune system of broiler chickens during starter (7-24) and grower (25-42) periods. a total of 288 male broiler chicks of ross 308 strain were used in a completely randomized design with factorial arrangement (2×4) with three replicates in each trea...
An experiment was conducted with the male Ross broiler chicks from 1 to 42 days of age to test the effects of different dietary protein and lysine levels on performance, carcass characteristics, and N excretion. Treatment diets consisted of three levels of supplemental lysine in starter and grower period (0, 0.15, and 0.30 %) and the two levels of protein (20.84, 17.84 in starter, and 18.12, 16...
s of papers 37 151 Live performance and meat yield responses of straight-run broilers to progressive concentrations of dietary energy maintained at a constant ME:Protein ratio. M. A. Hidalgo*, W. A. Dozier, III, A. J. Davis, and M. E. Freeman, University of Georgia. According to a popular benchmark reporting service, a diverse array of metabolizable energy values is being used in formulating di...
