Extract

In modern dairy cows, poor fertility is an ever-increasing problem. Milk progesterone analysis has revealed that this poor fertility is associated with a high incidence of reproductive cycle problems during the post partum period and with reduced progesterone secretion following mating. One of the likely causes of these problems is the increasing metabolic demand placed on these cows by increasing milk yield. In recent years, the search for an endocrine link between nutritional status and reproductive function has focussed on leptin. The aim of the present study was to determine whether plasma concentrations of leptin differ between cows with and without post partum reproductive problems and to determine if any relationship exists between plasma leptin and post mating plasma progesterone concentration.
