6.00 Megalac 0.30 S. B. P. Molassed 2.00 Wheat 3.00 Dist. 7.00 To avoid metabolic problems such as ketosis and milk fever, all cows are given a dose of Calcijet at calving. Calcijet provides a highly available source of energy, chelated calcium and chelated magnesium to the freshly calved cow. A 100ml dose of Breeder Plus is also administered at 7 days post calving with a view to boosting the cows levels of essential minerals and trace elements. 3.0-3.5 and maintain this through to calving.
Grazing is restricted and adjusted as required to maintain the condition of the cows.
The cows are given access to ad lib . Where cows continue to show signs of molybdenum toxicity, Cosecure boluses are administered. A high proportion of the protein in a precalver cake will not be broken down in the rumen, and therefore will build up the cows own tissue reserves allowing for a higher level of milk protein in the next lactation. Past experience has shown that low calcium and high phosphorus levels in the precalver cakes help reduce the risk of milk fever and reduce the incidence of retained afterbirths and other calving problems. On analysis of the grazing land, levels of phosphate and potash were found to be sufficient, necessitating the application of nitrogenous fertiliser only on the majority of the land.
