The objectives of this study were to investigate the effect of dietary folic acid levels on productive performance of Baheij as a local Egyptian chicken strain and the transfer of folic acid in the eggs as related to hatchability and egg weight loss during incubation and hatched chick weight. One hundred and five laying hens and 21 cocks aged 32 weeks of age from Baheij chicken strain were rand...

We investigated the effects of dietary supplementation of zinc (ZnO; 0, 40, 80, 120 and 160 mg/kg) and Vit E (α-tocopheryl acetate; 0 and 40 IU/kg) on egg production, egg quality and Zn content of egg fractions and tissues in Japanese quails. Using a 5 × 2 factorial design, a total of 960 Japanese quails (Coturnix coturnix japonica) at day 70 of age were housed in cages and randomly assigned in...

The effects of organic and inorganic sources and concentration (0 and 0.3 mg per kg of diet) of Selenium (Se) on growth performance, blood biochemical and immune system were evaluated in broiler chickens. Chickens were fed corn-soy-based diets formulated to 8 dietary treatments containing no added Se (negative control), negative control plus yeast (positive control), and 6 diets had 0.3 mg/kg o...

Obesity is defined as accumulation of excess fat in body associated with adverse health outcomes [1]. Although consensus is lacking, a body fat content of more than 20-25% in boys and 25-32% in girls are associated with morbidity [2,3]. Socioeconomic advancements leading to nutritional transition from a traditional diet to a high fat, refined carbohydrate containing diet accompanied by sedentar...

The study was conducted on male mice (Albino mice), which ranged in age from (2-3) months and weights (25 - 30) g. experiment the General Company for manufacture of medicines medical supplies Samarra. And period beginning October 2017 to end March 2018, Used 42 animals were distributed seven groups, each containing 6 animals, determine effects both gannoderma spirulina laboratory induced by dia...

CONTEXT Isolated soy protein reduces plasma concentrations of total and low-density lipoprotein (LDL) cholesterol. OBJECTIVE To identify the agent(s) responsible for the cholesterol-lowering effect of soy in mildly hypercholesterolemic volunteers: isoflavones isolated together with soy protein or soy protein itself. DESIGN Double-blind randomized parallel trial. SETTING Single-center stud...

Effects of phenytoin (PHT) administration on dental caries in rats infected with Streptococcus sobrinus 6715 were investigated. Twenty-day-old specific pathogen-free Fischer male rats were infected with S. sobrinus 6715 and fed diet 2000 containing 56% sucrose with or without PHT for 52 days. Antibody responses against anti-S. sobrinus in serum and saliva failed to show a statistical difference...

It was demonstrated by Elvehjem and collaborators (l-4) that, if to a niacin-free diet containing 9 per cent casein and permitting moderate growth there was added an excess of tryptophan-deficient proteins (corn, gelatin, acid hydrolysates of proteins) or certain amino acids (glycine, threonine, phenylalanine), growth of young rats was impaired or stopped. Furthermore, this effect could be abol...

Intervention studies have demonstrated that saturated fat increases total and LDL-cholesterol concentrations, and it is therefore recommended that the intake of high-fat dairy products be limited. However, observational studies have found an inverse relationship between the intake of dairy products and incidence of CVD. We aimed to study whether the Ca content of dairy products influences the e...
