Extract

Dairy cow productivity depends on efficient reproductive performance. A vital element of this is the prompt resumption of ovarian activity, which is normally expected by 35 days post partum. Cows will thus have a period of progesterone priming, which is considered necessary for satisfactory conception and embryo survival. Dry period nutrition has been shown to affect milk production during the subsequent lactation and this study was instigated to examine the possibility that the onset of ovarian activity may also be affected.
