Forty Alpine kids (20 females and 20 males) were used to determine effects of different levels of milk intake restriction and number of meals on starter diet intake and growth. Kids began the experiment at 3 to 9 d after birth (3.8 ± 0.15 and 4.2 ± 0.16 kg initial BW for females and males, respectively). A mixed starter diet was consumed ad libitum during the 10-wk suckling and 4-wk post-weaning periods; milk consumption was ad libitum for the first 2 wk. Treatments were: ad libitum consumption of milk in two meals in wk 3-8, then 50% of consumption on the preceding few days with one meal in wk 9 to 10 (AL); 75% of intake on the last few days of wk 2 in two meals in wk 3-8, then 50% consumption (67% of intake in wk 3-8) in wk 9-10 with one meal (R-2X); 75% consumption in one meal in wk 3-8, then 50% consumption in wk 9-10 in one meal (R-1X); and 75% consumption in two meals in wk 3-6, then 37.5% consumption in one meal in wk 7-10 (R-2X-1X). Milk DMI was greatest (P < 0.05) among treatments for AL (174, 115, 128, and 113 g/d for AL, R-2X, R-1X, and R-2X-1X, respectively). Starter diet DMI (g/d) was 19, 25, 19, and 35 in wk 3-4 (SE 6); 27, 37, 25, and 48 in wk 5-6 (SE 8); 51, 78, 72, and 143 in wk 7-8 (SE 16); 138, 194, 165, and 249 in wk 9-10 (SE 15); 343, 396, 388, and 417 in wk 11-12 (SE 47); and 508, 530, 489, and 539 in wk 13-14 (SE 38) for AL, R-2X, R-1X, and R-2X-1X, respectively. ADG was 163, 173, 175, and 175 in wk 1-2 (SE 8); 136, 84, 105, and 133 in wk 3-4 (SE 12); 114, 56, 87, and 102 in wk 5-6 (SE 20); 193, 132, 134, and 107 in wk 7-8 (SE 16); 87, 154, 96, and 136 in wk 9-10 (SE 22); 88, 110, 129, and 109 in wk 11-12 (SE 22); and 122, 108, 118, and 126 in wk 13-14 (SE 27) for AL, R-2X, R-1X, and R-2X-1X, respectively. In conclusion, restricted milk intake regimes can be used to increase dry feed consumption for ADG similar to that with ad libitum milk intake. Likewise, opportunities exist for unimpaired growth with restricted milk feeding in one meal daily during the latter portion of the suckling period.
