Summary Twenty-four calves from, four dairy breeds were used in a comparison of milk-replacer feeding systems. Group I received 32.2 lb. whole milk from four to ten days, and 53.2 lb. of milk replacer (dry basis) to 49 days of age. Groups II and III were fed no whole milk after the colostrum-feeding period and an average of 25.6 lb. of milk replacer (dry basis) to 30 days of age. The milk replacer was reconstituted in 100° F. water and fed via open pail. The starter fed to Group III was improved by using a special processed soybean flour-whey soluble product in the place of soybean meal, dried skimmilk, and distillers corn solubles. Average body weight changes were slightly greater for Group I and lowest for Group II. However, differences were not statistically significant. Alfalfa hay (fed from seven to 60 days of age) consumption was similar for all groups. Starter intake was 80.3, 92.2, and 105.0 lb. for Groups I, II, and III, respectively. It was possible to eliminate whole milk after the colostrum-feeding period, to discontinue milk-replacer feeding after 30 days of age, and to use modified starter in order to raise young dairy calves successfully.
