640 Hy-Line W36 white Leghorn laying hens regarding their ages (28 and 44 weeks) were divided into two 64 groups of 5 bird per cage (16×4 factorial test). 16 experimental diets included a corn soybean meal basal diet containing 50mg/kg Zn and 30mg/kg Mn supplemented with 0-0, 0-30, 0-60, 0-90, 50-0, 50-30, 50-60, 50-90, 100-0, 100-30, 100-60, 100-90, 150-0, 150-30, 150-60 and 150-90 mg/kg of Zn...

The present study investigated the impact of dietary supplementation with nano-elemental, inorganic, and organic selenium (Se) on Se content, fatty acid (FA) composition, oxidative stability meat in 150 one-day-old broiler chickens. chickens were allotted into three groups: control (C), SS+SY, SeNP. C group received a diet without any added Se, while SS+SY SeNP groups fed diets containing 0.4 m...

This study was conducted to determine the effect of different levels organic copper (organic Cu) supplementation on performance, egg quality, serum parameters and incubation characteristics in Japanese quail diets. 120 breeder quails 7 weeks old were used lasted 84 days. Four diets containing (0, 75, 150 225 mg/kg) study. The a random design consisting 20 subgroups with 5 replicates, 4 females ...

Marigold flower extract (MFE), a natural source of xanthophylls, was added to the diets of hens at different concentrations (0, 150, 250, and 350 mg/kg of diet) to determine the effects of MFE on hen performance, physical characteristics of egg quality, and carotenoid content of the egg yolk of hens housed in enriched cages. Additionally, the highest dose of MFE (350 mg/kg) was tested under com...

The palatability of different cereals was studied in 2 two-way choice (preference) experiments using pigs of 56 d of age and 17 kg of BW. In Exp. 1, the effect of 24 cereals vs. a common reference diet containing white rice on feed preference in pigs was studied. Pigs were offered free choice between the reference diet and a diet with the cereal under study for 4 d. Barley, corn (2 sources), wh...

To examine the hormonal effects of isoflavones, of which soyabean is a rich source, fifteen healthy nonvegetarian premenopausal women were studied over 9 months. They lived in a metabolic suite for between 4 and 6 months where their diet and activity levels were kept constant and their hormonal status was measured over two or three menstrual cycles. During one (control) menstrual cycle a normal...

A 3 × 2 factorial experiment was conducted to investigate the effect of thymol + carvacrol (0, 100 and 200 mg/kg) on ileal microbial population and jejuna and ileal histomorphology of broilers fed Carboxy Methyl Cellulose (CMC: 0 and 2%) containing diet. Each of the 6 dietary treatments was replicated 5 times with 12 chicks each from 0 to 42 days of age. There was no interaction effect of CMC a...

this study was conducted to evaluate the effect of supplementing diets of milking cows monensin supplementation alone or in combination with methafix (a commercial product containing malate and fumarate) on nutrient digestibility, milk production and composition and milk fatty acids profile. using four multiparous holstein milking cows (657± 12 kg of live weight; 133 ± 41days in milk) in a lati...
