The effect of dietary nonphytate P (nPP) and Ca concentration on the Ca appetite in broilers was evaluated. A total of 288 one-day-old male Ross 308 broilers were fed a commercial diet for 7 d then randomly allocated to 1 of 8 dietary treatments for a 28-d study. Diets were corn-soybean meal based and formulated to be nutritionally adequate except for nPP and Ca. Two concentrations of Ca (5.0 a...

A 294-day study was conducted to determine the effects of organic and inorganic copper (Cu) sources on laying performance, blood and yolk cholesterol and Cu accumulation in the yolk of laying hens. 480 Kabir® laying hens (20 weeks old) reared for 294 days in three phases (early, mid and late lay) were used. They were randomly allocated to six dietary groups of 80 birds split into four replicate...

this experiment was performed to investigate the effects of propolis and chromium picolinate on performance and immune response of broiler chicken under heat stress conditions. treatments included different levels of propolis (500, 1000, and 1500 mg/kg) and chromium picolinate (1500 µg/ kg) along with a control group. a completely randomized design was taken into account with 4 replicates of 10...

the effect of feeding frequency on growth performance, feed consumption and body biochemical composition of acipenser ruthenus juveniles was investigated. the trial was performed using 150 fish with a mean initial weight of 50±1 g randomly introduced in fifteen tanks. fishes were fed at a feeding frequency of twice daily (t1), three times a day (t2), four times a day (t3), five times a day (t4)...

Three levels of lysine (90, 100 and 110% of Ross requirement) and of pyridoxine (3, 6 and 9 mg kg-1) were used in a 3 × 3 factorial experiment to investigate the growth and blood antioxidant ability of broilers under high ambient temperature. None of the dietary supplements affected the weight gain during the starter and grower periods. Although no significant differences were detect...

in order to study the effects of artichoke leaf powder on the quality parameters of thigh and breast meat and the fatty acids profile of breast meat, 240 day-old japanese quails were used. the brids were assigned to 4 treatments including basal diet (control), basal diet supplemented with levels of 15 and 30 g/kg artichoke powder and 300 mg/kg vitamin e with 4 replicates for each treatment in a...

This study compared the nutritional value of canola (B. napa) and mustard (B. hirta) press cakes obtained from the biodiesel industry as ingredients for use in diets fed to broiler chickens. A total of 210, one-day old, male broiler chicks were randomly assigned to one of seven dietary treatments. The control diet was based on wheat and soybean meal and contained 15% canola meal. For the experi...

AIM The present experiment was conducted to study the effect of post hatch dietary fat supplementation on performance of broiler chicken. MATERIALS AND METHODS A total of 120 day-old Ven Cobb broiler chicks were randomly assigned to 4 treatment groups of 30 chicks in each (three replicates of 10 birds/treatment). The trial lasted for 35 days. The experimental design was a completely randomize...

One hundred and eighty 28-days-old Arbor Acres broiler birds were utilized in a 28 day experiment to investigate the effect of replacing bone ash with eggshell meal in the diet of broiler birds on their nutrient digestibility and blood parameters. Five experimental diets tagged T1, T2, T3, T4 and T5 were formulated to be isocaloric (2865.53 kcal ME/kg) and isonitrogenous (20% crude protein) suc...

This study was performed to investigate the effects of dietary threonine (Thr). level on performance, metabolizable energy, intestinal morphology, and immune system in coccidian–infected broiler chickens. The diets contained: 88%, 100% (Non challenged (NC) and challenged control (PC)), 112%, 124%, and 136% of Thr requirement according to Cobb 500 recommendation and fed during grower (pre challe...
