This experiment was conducted to study the effects of using cotton-seed meal on the performance and carcass yield of broiler chickens at different ages. The experiment was performed in a completely randomized design with four treatments and five replicates for each treatment. The experimental treatments included the levels of 0, 3.5, 7, and 10.5% of cotton-seed meal in diets fed to chickens at ...
The study evaluated the effect of a novel commercial preparation of natural blend of essential oils from basil, caraway, laurel, lemon, oregano, sage, tea, and thyme (Tecnaroma Herbal Mix PL) on growth performance, blood biochemistry, cecal morphology, and carcass quality of broilers. Six nutritionally adequate wheat and soybean-based diets were generated by the addition of Tecnaroma Herbal Mix...
OBJECTIVE Vitamin D deficiency (25-hydroxyvitamin D [25(OH)D] <50 nmol/L) is commonly reported in both children and adults worldwide, and growing evidence indicates that vitamin D deficiency is associated with many extraskeletal chronic disorders, including the autoimmune diseases type 1 diabetes and multiple sclerosis. RESEARCH DESIGN AND METHODS We measured 25(OH)D concentrations in 720 cas...
Asian Indians who immigrate to northern Europe have lower serum 25-hydroxyvitamin D [25(OH)D] than Caucasians, and they develop vitamin D deficiency, rickets, and osteomalacia. We investigated vitamin D metabolism, the effects of 25(OH)D3 on vitamin D metabolism and activity of 25(OH) D-24-hydroxylase, the rate-limiting enzyme for degradation of 25(OH)D, from cultured skin fibroblasts of Asian ...
This interlaboratory study on determination of 25-hydroxyvitamin D (25-OH-D) in serum involved 15 laboratories in eight European countries. All could distinguish between normal (50 +/- 31 nmol/L, mean +/- SD) and grossly increased concentrations, but for eight laboratories the results for serum samples with low and normal 25-OH-D content overlapped. In general, values were well reproducible, bu...
25-Hydroxy-24-oxovitamin D3 (25(OH)24-oxo-D3), a metabolite of 25-hydroxyvitamin D3, has been chemically synthesized. The ultraviolet, mass, infrared, and proton nuclear magnetic resonance spectra of the 25(OH)24-oxo-D3 were identical with those of the natural product isolated from chick kidney incubates. The oxo compound showed biological activity similar to 24,25-dihydroxyvitamin D3 (24,25(OH...
Introduction The main aim of this study was to compare serum level of 25- hydroxyl vitamin D [25(OH) D] between women with preeclampsia and normal individuals and birth outcomes. Material and Methods This cross sectional study was conducted on 650 normal primigravida women in their first 24–28 weeks of pregnancy. After 3 months of follow-up, serum levels of 25(OH) D and calcium were measured...
An experiment with a 33 factorial arrangement in a completely randomized design with 450 day-old broilers was conducted to study the effect of energy level and time of change from starter to finisher diets on performance and economic aspects of broilers. Broiler chickens were fed at three levels of dietary energy (2800, 3000, and 3200 KcalME/Kg) from 1-42 days of age. Starter and finisher diet...
