As there is a possibility that Se influences the growth of animals via thyroid hormone metabolism, the following three experiments were undertaken in order to determine the effects of dietary Se on growth, skeletal muscle protein turnover and thyroid hormone status in broiler chickens. Broiler chickens were raised on a Se-deficient diet until 12 d of age and then used for the experiments. In Ex...

A study was conducted to determine the effects of dietary vitamin C on growth performance, feed utilization and carcass biochemical composition of Barbus sharpeyi fingerling. Five diets containing (0, 500, 1000, 1500 and 2000 mg kg-1) of ascorbic acid were fed to benni fingerlings (6.96±0.3 g) in triplicate tanks and twice daily for a period of 56 days. The weight gain significantly increase...

We studied the influence of dietary fat source and dl-α-tocopheryl acetate and ascorbic acid supplementation on the sensory quality of cooked dark chicken meat stored at −20 C for different periods. Results showed that dietary fat source and α-tocopheryl acetate supplementation influenced sensory scores (rancid flavor and aroma and acceptability). Ascorbic acid had no influence on these scores....

The effect of dietary thyme-oil extract (TOE) supplementation on immune functions of broilers were assessed by feeding graded levels (50, 100, 200, or 400 ppm) of TOE to male broiler chicks during a 42-d feeding trial compared with negative- or positive-control diets. Dietary control treatments included a negative-control diet with no feed-additive supplementation and 2 positive-control groups ...

this study was carried out to investigate the effects of 1, 25-dihydroxycholecalciferol (1, 25 (oh)2 d3) and root hydroalcoholic extract of withania somnifera (ws) root on performance, mineral retention, bone mineralisation and mechanical characteristics of broiler chicks. treatments were arranged factorially (2×3×2) consisted of a positive control with adequate ca and a negative control diet (...

Twenty-eight day feeding trial was conducted to evaluate the performance of broiler finisher fed soybean hull based diets supplemented with “Safzyme®”, an exogenous cellulolytic enzyme. Soybean also referred as soyhull, millrun or flakes are by-products milling industry. Five were formulated such that contained meal at 0%, 10% and 20% dietary levels (without enzyme supplementation) 10%, (with 1...

Dietary fiber is a non-digestible carbohydrate providing beneficial effects for bowel health. The aim of this study was to evaluate the clinical effects of fiber supplementation in enteral feeding on elderly patients suffering from diarrhea. This study was conducted in 15 patients (7 men and 8 women, 79.0 ± 7.5 years) who had loose stools or diarrhea during enteral nutrition. The enteral formul...

Folate is generally considered as a safe water-soluble vitamin for supplementation. However, we do not have enough information to confirm the potential effects and safety of folate supplementation and the interaction with vitamin B(12) deficiency. It has been hypothesized that a greater methyl group supply could lead to compensation for vitamin B(12) deficiency. On this basis, the present study...

This study evaluated the effect of a combination of mannan-oligosaccharides (MOS) and microbial phytase (MP) on growth performance, some blood biochemical metabolites, intestinal morphology and cecal microbial population of ROSS 308 broiler chickens from d 0 to 35 of age. A total of 200 one-dayold broiler chickens (mixed sex) were randomly distributed into four treatments with five replicates a...
