- Poor lamb growth rates
- Infertility in ewes as a result of embryonic mortality which occurs three to four weeks after conception. This results in a higher percent of barren ewes and a low lambing percentage
- Poorer motility and increased morphological defects in ram sperm
- White muscle disease in lambs, characterised by a non-inflammatory degeneration or necrosis of the skeletal and cardiac muscles. Lambs are born dead or die suddenly within few days of birth. Some deaths occur three to six weeks after birth (delayed white muscle disease).
In Crops and Pasture: N/A – Selenium is not required in crops and pastures directly. Selenium is added to maintenance and capital fertiliser blends as an efficient way of getting adequate Selenium into livestock.
