Eighteen ewes were randomly assigned to one of three treatment groups: control, injected vitamin E, and injected selenium, with the objective of evaluating the effect of these treatments on the concentration of vitamin E and selenium in the milk. Vitamin E injections were given by intramuscular injection at the rate of 2000 IU per ewe at lambing and at 6 wk after lambing. Selenium supplementation was given by intramuscular injection at the rate of 12 mg sodium selenite at lambing and at 5 wk after lambing. Milk samples from all ewes in the three groups were collected for determination of vitamin E and selenium 0, 1, 2, 7, 14, 21, 28, 35, 42, 49, and 56 d after lambing. Ewes injected with vitamin E or selenium at lambing increased the concentration of these nutrients in milk during the first 14 d of lactation; as a result, increased amounts of vitamin E and selenium were available to suckling lambs during their early days of life. Milk levels of selenium but not vitamin E were increased by subsequent injection of selenium or vitamin E, respectively. It was also observed that colostrum contained higher concentrations of both vitamin E and selenium than did whole milk. Key words: Vitamin E, Se, milk, ewes

ABSTRACT Studying vitamin E [α-tocopherol (α-T)] metabolism and function in the brain and other tissues requires an animal model with low α-T status, such as the transgenic α-T transfer protein (Ttpa)–null (Ttpa−/−) mouse model. Ttpa+/− dams can be used to produce Ttpa−/− and Ttpa+/+mice for these studies. However, the α-T content in Ttpa+/− dams’ diet requires optimization; diets must provide sufficient α-T for reproduction, while minimizing the transfer of α-T to the offspring destined for future studies that require low baseline α-T status. The goal of this work was to assess the effectiveness and feasibility of 2 breeding diet strategies on reproduction outcomes and offspring brain α-T concentrations. These findings will help standardize the breeding methodology used to generate the Ttpa−/− mice for neurological studies.

The responses in liveweight, wool weight and survival, to selenium supplementation, were studied in young sheep from weaning to yearling age. The experiment was conducted over three years. In the first year, one sodium selenite supplementation rate was used (total dose 46.5 mg). During the following two years two supplementation rates were administered (total doses 46.5 mg and 93 mg). Mean concentrations of selenium in whole blood in unsupplemented sheep varied from 0.19-0.56 pmol l-l and from 0.20-0.44 pmol l-1 in the two years in which concentrations were measured. Supplementation, which commenced at lamb marking, increased the selenium concentration in sheep at weaning and thereafter. Selenium supplementation improved the break-of-season weight (P < 0.01) and yearling weight (P < 0.01 ) but not weaning weight (0.05 < P < 0.1 ). Hogget fleece weight was improved (P < 0.01 ) and mortality reduced (P < 0.01) by selenium supplementation. There was a treatment x year interaction in mortality rates (P < 0.01 ). There were no significant differences between the two supplementation rates
