Abstract
The objectives of this study were to determine the effects of prepartum supplementation with inorganic selenium (INORG), organic selenium (ORG) or a rumen-protected choline, on the triglyceride (TAG) and total fatty acid (TFA) profiles of bovine colostrum and transition milk. Fifty-seven Holstein Friesian (HF) and HF × Jersey cows were supplemented daily from 49 ± 12.9 days prior to calving until day of calving. Milk samples were analysed for TAG and TFA composition using GC-FID. Prepartum supplementation did not have a significant effect on the milk lipid profiles. This study quantified colostrum lipids not previously reported in the literature.
期刊介绍：
The International Journal of Dairy Technology ranks highly among the leading dairy journals published worldwide, and is the flagship of the Society. As indicated in its title, the journal is international in scope.
Published quarterly, International Journal of Dairy Technology contains original papers and review articles covering topics that are at the interface between fundamental dairy research and the practical technological challenges facing the modern dairy industry worldwide. Topics addressed span the full range of dairy technologies, the production of diverse dairy products across the world and the development of dairy ingredients for food applications.
