Extract

In any cattle production system, reproductive performance is of central importance. The output from beef cow systems is calves, while lactation in the dairy cow is only achieved following parturition. On a world basis, the major cause of poor reproductive performance is inadequate nutrition, and in most cases this is represented by an inadequate energy supply, although in specific circumstances particular vitamin, mineral or disease problems can occur. This review considers how nutrition, and in particular energy nutrition may act via the endocrine system to influence reproductive performance in cows. The paper will consider the post-partum anoestrous period, fertilization and embryo mortality.
