In dairy production, “weaning readiness” is often based on solid feed intake. The goal of this study was to determine weaning readiness using feed-intake, lying-behaviors, and the use of an environmental enrichment device (EED) in calves that underwent 1 of 4 milk-replacer and weaning protocols. Twenty-eight male Holstein calves (95 ± 2.6 lb BW at 1 d of age) were housed in individual pens and initially fed one type of milk replacer (25% crude protein (CP), 17% fat, 1.45 lb of dry matter (DM)) via nipplebuckets twice a day (AM and PM), and one type of textured calf starter ( …

The objectives of this study were to determine the impacts of feeding preweaning heifers with a high protein milk replacer (MR) or a raw or pasteurized non-saleable milk (NSM) on preweaning and first lactation performance. Holstein heifers (n = 154) were blocked by birth date and weight (BW) and within block randomly assigned to 1 of 3 treatments: 1) MR (4% protein and 2.6% fat, liquid basis); 2) pasteurized NSM (PNSM, 3.6% protein and 4.1% fat, liquid basis); or 3) raw NSM (RNSM, 3.6% protein and 4.1% fat, liquid basis). Heifers in RNSM were fed raw colostrum whereas heifers in …
