Comparison of the effects of high and low milk-replacer feeding regimens on health and growth of crossbred dairy heifers
Sign Up to like & getrecommendations! Published in 2019 at "Animal Production Science"
DOI: 10.1071/an18432
Abstract: Context Pre-weaning growth in dairy heifers is highly dependent on the amount of milk fed. Both milk replacer (MR) and associated labour are costly, encouraging restricted milk rations and once-a-day feeding. Aims This study compared… read more here.
