this experiment was conducted with broiler chickens to evaluate the effects of high and low swelling bentonite (natural and processed by cuso4) supplementation in diets on performance and carcass traits. a total of 300 day-old aryan broiler’s chicks were used in a completely randomized design with 5 dietary treatments. six pen replicates of 10 chicks were assigned to each of five dietary treatm...

A 2×2 factorial experiment was conducted to study the effect of dietary calcium and non-phytate phosphorus (nPP) imbalance on calbindin and NaPi-IIb mRNA levels in the small intestine and tibia parameters of broiler chicks. One hundred and forty four 1-d-old Arbor Acres male broiler chicks were divided into four treatments consisted of six replicates with six chicks each. The two dietary calciu...

this study was carried out to indicate the effects of olive leaves on arterial blood pressure, blood lipids and growth performance in broiler chickens. experiment was conducted with 5 treatments and 4 replicates with 25 birds per each replicate in a completely randomized design with over all 500 male arian strain 1-day old broilers. the period of study was 42 d. treatments were control, drug of...

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 study was conducted to assay the use of saturejahortensis l. (savory) essential oil in the drinking water on broiler production and blood glucose, uric acid, creatinin and cholesterol. four hundred and twenty day old broiler chickens (ross 308) was used in a completely randomized design with 6 treatments and 5 replicate. experimental treatments included: 1) control, 2) tween (a solvent for...

The objectives of this work were to study the responses of one Leghorn and two broiler stocks and sexes to different levels of Thr and to estimate their requirements for this amino acid. All experiments were conducted with birds from 1 to 18 d of age. Body weight gain (BWG) and feed consumption were measured on the eighteenth day, and feed conversion ratio (FCR) was calculated. At Day 18, three...

This study was conducted to determine the dietary effect of graded levels unripe plantain peel meal on growth performance and internal organs broiler chickens. One hundred five (105) day-old unsexed Arbor Acre chicks were used in a56-day feeding trial. The birds assigned 5 treatments (T1- T5) with a total 21 per treatment replicated three times 7 replicate completely randomized design (CRD). T1...

This experiment was conducted to evaluate the effects of caffeine and trans-cinnamaldehyde (TC) on growth performance, hematological parameters, stress hormones, immune response, and some blood parameters of broiler chickens. Three hundred fifty 1-d-old broiler chicks were randomly assigned to 7 dietary treatments (five pens/ treatment of 10 male broilers each) in a completely randomized desig...

BACKGROUND: Growth promoters are chemical and biologicalsubstances that are added to livestock food with the aimto improve the growth of chickens in fattening and the utilizationof food, and in this way achieve better production and financialresults. OBJECTIVES:An experiment was conducted to evaluatethe effects of enzyme complex, probiotic, and their combinationon performance of broilers fed a ...
