New research has identified genes that control vitamin E content in maize grain, a finding that could lead to improving the nutritional profile of this staple crop.Cornell University scientists and co...
The objectives of the trial were to investigate the effects of supplementing vitamin E (VE) on nutrient digestion, nitrogen (N) retention and plasma parameters of beef cattle in feedlot. Four growing ...
The considerable increase in oxygen requirements due to the high metabolic rate of the bovine mammary epithelial cells (BMEC) during lactation results in an augmented production of reactive nitrogen s...
Two in vitro trials were carried out to study the effects of supplementing vitamin E (VE) on rumen fermentation. In Trial I, four levels of VE product (purity 50%), i.e. 0, 15, 30, and 60 mg/kg dry ma...
The aim of this study was to evaluate the effect of dietary supplementation with hemp seed oil (HSO) on the lipid metabolism, through the plasma lipid profile, liver function and concentrations of f...
Concentrations of calcidiol, calcitriol, and minerals in blood serum and colostrum of 14 primiparous and 16 multiparous Holstein dairy cows during short-period prepartum and postpartum were determined...
Two hundred and forty laying hens were fed diets supplemented with vitamin C and selenium (Se). Vitamin C was added at 0 or 200 mg/kg, and Se was added as sodium selenite or selenized yeast at 0.3 mg/...
The expression of avian β-defensins (AvBDs), Toll-like receptors (TLRs), and vitamin D receptor (VDR) following in vivo vitamin D3 injection was studied. Healthy 90-day Silky Fowls were abdominally in...
A 2 × 3 factorial design experiment was conducted to evaluate the effect of adding lycopene (0 and 75 mg/kg) and vitamin E (0.50 and 100 mg/kg) to the diet of chickens. Moreover, the study investiga...
The paper reports data from four experiments (EXP). Broiler cockerels Ross 308 were allocated to 3 or 5 (EXP 4) dietary treatments comprising 300 (3 replicated pens of 100 chicks per pen), 50, 50 or 1...
The effect of supplementing dietary selenium (Se) and vitamin E was investigated in 330 24-week-old laying hens. The hens were fed a basal diet containing Se and α-tocopherol at 0.11 and 26 mg/kg, res...
We examined the influence of a diet containing 4% of rapeseed oil, 35 mg or 126 mg copper and supplement of 100 mg vitamin E per 1 kg on fatty acid profile and cholesterol content in raw and cooked br...
An experiment was conducted to compare the effect of dietary sodium selenite and selenomethionine on selenium and α-tocopherol concentration in breast meat, oxidative stability of meat in broilers, an...
This study aimed to determine the effects of parenteral selenium (Se) and vitamin E supplementation on economic impact, milk yield, and some reproductive parameters in high-yield dairy cows in the dry...
This study aimed to evaluate the effects of vitamin E (VE), ferulic acid (FA) and their combination supplementation on meat quality and antioxidant capacities of finishing pigs. Sixty barrows were ran...
