Influence of Inorganic and Organic Selenium Sources on Broiler Performance and Meat Quality
An experiment was carried out to evaluate and compare the effects of organic and inorganic selenium (Se) sources on broiler male birds (Ross 308). Uniform broiler male chicks divided in to five groups with six replicates were fed with either normal feed (without supplemental Se, negative control), 0.25 ppm of inorganic Se, 0.5 ppm of inorganic Se, 0.25 ppm of inorganic Se + 0.25 ppm of organic ...

15 صفحه اولOrganic and inorganic selenium: III. Ewe and progeny performance.
Selenium is an essential micronutrient in sheep, and deficiency can limit lamb growth and survival. To evaluate how different chemical forms of Se administered to mature ewes at comparative dosages affect ewe and progeny performance, 240 ewes were divided into 8 treatment groups (n = 30 each) and drenched weekly with no Se; at the maximum FDA-allowed concentration with inorganic Na-selenite or ...
متن کاملEffect of organic and inorganic selenium sources and levels on sow colostrum and milk selenium content.
A study was conducted to evaluate the short-term effects of feeding two dietary Se sources at various Se levels on the transfer of Se to the dam's milk and nursing pig. Six dietary treatments were arranged in a 2 x 2 factorial arrangement with two additional treatments in a randomized complete block designed experiment. Inorganic (sodium selenite) or organic (Se-enriched yeast) Se sources were ...
