Low Selenium

In this study, the selenium content of forage from farms in northern Ontario where nutritional muscular disease is very severe was less than 0.1 p.p.m. Variations in the sulphur content of forage did not appear to affect the occurrence of the disease. A combination of vitamin E and selenium given to pregnant dams or directly to calves was completely effective in preventing the disease. Data on the selenium content of the hair of dams and calves are presented. Calves, sick or dead from white muscle disease, were born to cows with low selenium content of the hair (range 0.06–0.23 p.p.m.). No white muscle disease was observed in calves from dams with selenium content of the hair above 0.25 p.p.m. Selenium content of the hair was generally greater in the selenium-treated calves or those born to selenium-treated dams. It seems probable that the selenium content of hair may be a helpful factor in diagnosing white muscle disease.

In two experiments Merino breeding ewes were fed wheat in pens (wheat/pen) or small paddocks (wheat/paddock) from joining to weaning. Three levels of wheat were examined in each experiment (L1, M1, H1-experiment 1 ; L2, M2, H2-experiment 2) and at each wheat level a group of ewes received vitamin A. Control groups of ewes were run at pasture. The percentage of ewes pregnant in experiment 1 was higher in groups fed pasture than in groups fed wheat. There were no differences due to wheat level or vitamin A treatments. In experiment 2 there was an interaction between treatments in their effects on pregnancy rate. In experiment 2 wheat level had a linear effect on the proportion of multiple births and wheat/pen ewes gave birth to fewer twins than wheat/paddock ewes. The effects of wheat level on lamb birth weight were linear and quadratic in experiments 1 and 2 respectively. Lamb survival between birth and weaning was not influenced by wheat level or vitamin A in experiment 1. Lamb survival among groups fed wheat and pasture was 46 per cent and 84 per cent respectively. In experiment 2 there was an interaction between the treatments in lamb survival. In experiments 1 and 2, 66 per cent and 53 per cent respectively of lamb deaths among groups fed wheat were attributed to starvation. Goitre was diagnosed in 9 per cent of dead lambs from the wheat/pen groups of experiment 2. In both experiments white muscle disease was found in dead lambs from the wheat/pen groups.

This paper reports on the status of vitamin E and selenium in weaner and adult sheep in Western Australia (WA) during autumn, and its relationship to the incidence of apparent white muscle disease (WMD). A survey was conducted in which blood samples were taken from 10 weaner sheep (8–12 months of age) and 10 adult ewes (3 years of age) from flocks on 38 properties within the main southern agricultural region of WA, an area carrying ~10 million sheep. Deficiency of vitamin E was defined as a plasma α-tocopherol concentration less than 0.7 mg/L. Selenium deficiency was defined as whole blood glutathione peroxidase (GPx) activity less than 50 U/L. Incidence and severity of apparent WMD were defined in terms of elevated plasma activities of creatine kinase (CK) or aspartate aminotransaminase (AST). Of the weaner flocks, 58% (22/38) had mean plasma vitamin E concentrations in the deficient range (<0.7 mg/L) and 50% (19/38) had mean CK activities above 400 U/L (mild WMD); four of these flocks had mean CK activities over 1200 U/L (severe WMD). Of all the individual weaner sheep sampled, 6% had plasma CK activities >1200 U/L. It is likely that the incidence of vitamin E deficiency would have been higher had it not been for unseasonal summer rain germinating pasture on eight of the survey farms in the northern wheat belt. Flocks from farms with an evident green flush to their pastures had higher vitamin E levels than flocks grazing dry pasture. Vitamin E deficiency was less common in adult sheep than weaner sheep, with only 16% of flocks (6/38) having mean plasma concentrations below 0.7 mg/L and 11% (4/38) with CK values above 400 U/L. Selenium deficiency was less common than vitamin E deficiency and was mostly confined to adult flocks, with only 5% (2/38) of these having mean GPx values below the critical value of 50 U/g haemoglobin. For both weaner and adult sheep classed as vitamin E deficient, CK and AST activity in plasma was best described by a combination of plasma vitamin E concentration and whole blood activity of GPx (significant linear step wise regression, P < 0.001). The present study shows that subclinical vitamin E deficiency (<0.7 mg/L) was widespread in weaner flocks in WA during autumn and that, based on the biochemical data, deficiency was associated with apparent severe muscle damage in 6% of weaner sheep sampled. Recommended strategies to treat weaner sheep showing signs of WMD include dosing with 2000–4000 mg vitamin E either by injection, oral drench or by spraying it onto supplementary grain. The level and frequency of dosing depends upon the severity of the WMD symptoms. Less is known about preventative treatment, but recent evidence suggests that providing weaner sheep with access to saltbush during autumn may prove to be a practically useful strategy. Selenium supplements should also be supplied to weaner and adult sheep in areas known to be selenium deficient.
