Retained Placenta

A healthy cow should expel the placenta within 24 hours of calving. This is an automatic immune response, so delayed expulsion can be an indicator of poor immunity. Retained placenta increases the risk of metritis and reduces the likelihood of the cow getting back in calf. An effective nutritional tool is to feed organic selenium throughout the dry period and transition. It is also important to achieve good calcium balance, as calcium is needed for muscle contraction. Cows must be fed on a balanced diet right through the transition period. Heat Stress Heat stress is caused by a combination of temperature (particularly high night temperature) and humidity. It can result in reduced feed intake, a drop in production and poor fertility. Cows are most vulnerable through transition and early lactation. Providing shade, ensuring adequate water supply, installing fans and water sprayers, and supplying more feed in the evening than the morning are all effective management strategies. Nutritionists can help by increasing the nutrient density of the diet to account for reduced feed intake.
