This study was conducted to investigate the effects of dietary curcumin on hepatic lipid metabolism and antioxidant capacity in Roman laying hens. A total 144 hens (28 weeks old) were allocated 4 treatments that included at concentrations 0, 50, 150, 250 mg/kg for 9 weeks. Each treatment had 6 replicates per group with replicate (2 birds/cage). The results showed supplementation decreased (P < ...

a trial was conducted to evaluate the performance of broiler birds which supplemented with a commercial inactivated probiotic. four hundred and fifty day old broiler chickens were allocated into 3 treatments with 6 replicates each. each replicate was placed on clean wood shavings in floor pens receiving feed and water ad libitum. in treatment 1, feed was supplemented with 500 g/ton of a heat-in...

Dried distillers grains with solubles (DDGS) can decrease rumen pH because of their inherent acidity. Two replicated 4 × 4 Latin square experiments were conducted with ruminally fistulated heifers to determine the effects of dietary inclusion and NaOH treatment of DDGS on rumen metabolism. In Exp. 1, dietary treatments were 0%, 20%, 40%, or 60% DDGS on a DM basis. The remainder of the diet was ...

An experiment was carried out to investigate the effects of different dietary levels of energy on growth performance and meat yields of indigenous (desi) chickens up to the target weight of 950 g in rural condition. One hundred indigenous unsexed chicks aged 4 weeks were considered for the feeding trial until the body weight reached at 950g. Chicks were divided into two dietary treatments havin...

This study was aimed to investigate the effects of L-carnitine (Car), creatine monohydrate (CrM) and their combination (CarCrM) as dietary antioxidants materials on productive performance, digestibility, ileal eubiosis, blood chemistry redox system stressed quails challenged by lead acetate (LA) in drinking water. In total, 600 were assigned into 5 treatments with 4 replications each 30 chicks ...

Five 28- to 33-d experiments involving 460 crossbred pigs weaned at 28 +/- 2 d of age (initial weight, 6.7 to 8.1 kg) were conducted to determine the effects of feeding high dietary levels of Cu sulfate (CuSO4) or Cu oxide (CuO) on rate and efficiency of gain and liver Cu stores of weanling pigs. The pigs were housed in groups of five to six/pen and fed a fortified, unmedicated, corn-soybean me...

This experiment was conducted to compare the effects of prebiotic as alternative feed additive to an antibiotic growth promoter (bacitracin methylene disalicyate) on the growth performance and morphometrical parameters of the small intestine of broiler chickens. One hundred and forty four day old broiler chicks were randomly assigned to one of three dietary treatments for 6 wk and each treatmen...

essential amino acids such as methionine have been increasingly included into diets of lambs. however, few studies have determined the effects of methionine supplementation in the general performance and economic returns of lamb production. to address this question, 21weaned male rahmani lambs were allotted to 3 dietary treatments: control diet (c), control diet plus 3.30 g of methionine/kg con...
