The profitability of high performance sheep production systems depends on targeting those management practices that are cost effective and will improve lamb survival.
Poor survival of newborn lambs is a major source of lost productivity in breeding enterprises where lambing percentages of 110-130 per cent born can result in a marking percentage of 70-90 per cent. Most of these losses are associated with poor ewe nutrition during pregnancy1.
Most lamb loss occurs in the three days after birth, so reducing lamb losses must focus on factors that can improve survival of newborn lambs. During late pregnancy and early lactation the lamb is entirely dependent on the ewe to provide essential vitamins and minerals for growth and development. Calcium in particular is in high demand for bone development, peaking when the lamb is 10-days of age1.
Given this, ewe condition at lambing is the most important determinant of lamb survival. In order to maintain good ewe condition and ensure lambs are healthy at birth, improving ewe nutrition and the provision of essential minerals and vitamins is key to this process.
With so much demand of minerals, trace elements and vitamins for the ewe, a complete and balanced supplement of available minerals (not just magnesium oxide) is paramount to optimum production.
