This study was conducted to evaluate the effect of different levels of sunflower meal (SFM) and niacin on laying hens performances, biochemical parameters, antioxidant status, and egg yolk cholesterol concentration. A total of 960, White Leghorn (Hy-Line W-36) commercial layers were randomly assigned to 12 groupsof 8 replicates with 10 hens each. Hens were allocated to diets 1 through 12 in a 3...

This study was conducted to investigate the influence of dietary rapeseed meal (RSM) on growth performance, blood profiles, nutrient digestibility and economic benefit of growing-finishing pigs. A total of 120 growing pigs ([Yorkshire×Landrace] ×Duroc) with an initial body weight (BW) 29.94±0.06 kg were used in this experiment. Pigs were randomly allotted into 1 of 5 treatments in a randomized ...

The aim of this study was to compare the effects of dietary supplementation of ajwain (Trachyspermum ammi) and thyme (Thymus vulgaris) essential oils(EO)on nutrients digestibility, blood parameters and growth performanceof neonatal dairy calves during eight weeks. Sixty suckling dairy calves with an initial body weight (43.2±3.8 kg) were randomly allocated to five treatments including CO, contr...

OBJECTIVE This study was conducted to determine the effects of dietary maifanite supplementation and fecal collection method on the apparent total tract digestibility (ATTD) of calcium (Ca) and phosphorus (P) and blood parameters in growing pigs. METHODS Thirty-six growing barrows (Duroc×Landrace×Yorkshire; 27.0±2.6 kg) were allotted to six dietary treatments with 6 pigs per treatment accordi...

A total of 150 growing ducks were assigned to five dietary treatments to study the effect of sea tangle and charcoal (STC) supplementation on growth performance and meat characteristics in a completely randomized design. There were six replicates and five ducklings in each replication. The five dietary treatments were control, antibiotic, and 0.1%, 0.5%, and 1% STC supplemented diets. No signif...

The greatest cause of fracture in older people is osteoporosis which contributes to increased morbidity and mortality in older people. A number of meta-analyses have been performed assessing the effectiveness of calcium supplementation alone, vitamin D supplementation alone and the combined therapy on bone loss and fracture reduction in older people. The results of these meta-analyses indicate ...

Gut microbiota was analyzed in children, aged 6-18 months and suffering from atopic dermatitis before and after 3 month supplementation of their diet with Lactobacillus casei DN--114001 in a dose of 109 cells daily. On completion of this period the total number of fecal Lactobacillus sp. cells decreased from 7.86 Log10 CFU/g to 6.40 Log10 CFU/g. After the next 5 months (without dietary suppleme...

The effects of supplementation with grass silage and replacement of some corn in the concentrate with soybean meal (SBM) on milk production, and milk fatty acid (FA) profiles were evaluated in a replicated 4 x 4 Latin square study using 16 dairy cows grazing pasture composed of ryegrass, Kentucky bluegrass, and white clover. Each experimental period lasted for 3 wk. The 4 dietary treatments wer...

BACKGROUND Complementary food supplements (CFSs) can enhance growth where stunting is common, but substitution for the usual diet may reduce observed benefits. OBJECTIVE We aimed to characterize dietary diversity from home foods in a CFS efficacy trial and determine whether supplementation reduced breastfeeding frequency or displaced home foods. DESIGN In a cluster-randomized controlled tri...

this research was carried out to investigate the effects of various levels of dietary organic selenium supplementation (0, 0.1,  0.2 and  0.3 mg/kg) on reproductive traits of rooster. semen was collected using abdominal massage and samples were mixed together. sperm characteristics including percentage of motile, viable and abnormal sperms were assessed. this experiment was carried out based on...
