Fertilization of ova in selenium/vitamin E-treated ewes maintained on two planes of nutrition.

Effects of Organic and Inorganic Selenium Supplementation with Vitamin E during the Flushing Period on Reproductive Performance of Ghezel Ewes

Minerals and vitamins play an important role in animal nutrition with beneficial effects on animal reproductive performance. To investigate this issue, 44 Ghezel ewes weighing 55±  2 kg (Mean±SD) and 2-3 years old were randomly divided into groups (n=11), to investigate the effect of the selenium and vitamin E supplementation on blood hormones and metabolites and possible reproductive performan...

Effects of selenium and vitamin e supplementation on concentrations of selenium and immunoglobulins in colostrum and blood of baluchi ewes and lambs and on lamb growth

Rearing, fattening performance and slaughter indicators of lambs after selenium, zinc and vitamin E supplementation

The experiment was conducted on 80 Polish Merino ewes, their 82 lambs and 40 fattening rams. Merino ewes were divided into two groups: experimental (E) and control (C), each composed of 40 animals. Four weeks before lambing, 1 day, 3 weeks and 6 weeks after lambing 40 ewes of the experimental (E) group received intramuscular injection of 5 ml 0.1 % Na2SeO4 (selenium [Se]: 2.09 mg), 10 ml 10 % Z...

Metabolism of vitamin E in sheep.

I . The metabolism of tritium-labelled tocopherol was investigated in thirty-six wethers and forty-two ewes fed on hay known to produce nutritional muscular dystrophy (NMD). 2. In one experiment, the effect of selenium or vitamin E or both on the metabolism of tritium-labelled tocopherol was studied. No difference was found in the incorporation rate of radioactivity in tissues due to the additi...

Use of injectable vitamin E and selenium-vitamin E emulsion in ewes and suckling lambs to prevent nutritional muscular dystrophy.

Forty-eight Blackbelly X Dorset, 27 Finnish, 26 Finnish X Dorset, 28 Rambouillet and 8 Dorset Suffolk-sired lambs were used in this experiment. Three weeks before lambing, one-half of the ewes received a selenium emulsion (Se-E) containing .05 mg selenium and 3.7 IU of vitamin E/kg body weight (BW). A 2 X 3 X 2 factorial arrangement was used; lambs from either treated or nontreated ewes were ra...
