This study investigated the effects of varying fat levels and ratios of coconut to palm fat in milk replacer on solid feed intake and performance of male Holstein calves fed a high milk replacer allowance. Calves were individually housed and enrolled in a 91-d (study 1; n = 128) and 84-d (study 2; n = 128) experiment at the same research facility divided into 3 phases: preweaning (1-42 d), weaning (43-63 d), and postweaning (64-study end). In study 1, calves were randomly assigned to 1 of the 3 treatments, consisting of a milk replacer containing a spray-dried blend of 20% coconut to 80% palm fat with: (1) low fat (17%; LF-17%; n = 42; BW = 47.64 ± 2.62 kg), (2) moderate fat (23%; MF-23%; n = 43; BW = 47.69 ± 3.42 kg), and (3) high fat (29%; HF-29%; n = 41; BW = 47.04 ± 3.74 kg) in relation to 26% CP level. In study 2, calves were randomly assigned to 1 of the 3 treatments with the same fat-to-CP ratio (21% fat; 26% CP), varying the ratio of coconut to palm fat in the spray-dried fat blend with: 1) 20% to 80% (20C:80P; n = 42; BW = 47.63 ± 4.40 kg), 2) 35% to 65% (35C:65P; n = 42; BW = 49.07 ± 5.30 kg), and 3) 50% to 50% (50C:50P; n = 44; BW = 48.48 ± 4.09 kg), respectively. Milk replacer was fed twice daily (130 g/L) following the step-up, step-down program: from d 0 to 6, 520 g/d; d 7 to 13, 650 g/d; d 14 to 20, 910 g/d; d 21 to 41, 1,040 g/d; d 42 to 48, 910 g/d; d 49 to 63, 650 g/d. Body weight and calf starter intake were recorded weekly. Mixed linear models were used with treatment, phase, and their interaction included as fixed effects. Initial BW, serum total protein, calf source, and total number of disease interventions were tested as covariates. In study 1, ADG was greater for calves fed a low-fat milk replacer over the 91-d period (LF-17% = 1.24 ± 0.02, MF-23% = 1.09 ± 0.02, HF-29% = 1.12 ± 0.03 kg/d). At 91d, BW was greater for LF-17% (LF-17% = 160.80 ± 2.11, MF-23% = 147.22 ± 2.17, HF-29% = 149.59 ± 2.26 kg). Total DMI was greater for LF-17% calves across the postweaning phase, leading to greater ME intake (LF-17% = 14.15 ± 0.22, MF-23% = 11.98 ± 0.22, HF-29% = 12.31 ± 0.23 Mcal/kg). During preweaning, LF-17% calves had greater feed energy efficiency. In study 2, ADG was greater for 35C:65P calves over the total period (20C:80P = 1.04 ± 0.02, 35C:65P = 1.11 ± 0.02, 50C:50P = 1.04 ± 0.02 kg/d). At d 84, BW was greater for 35C:65P dairy calves (20C:80P = 135.82 ± 1.97 kg; 35C:65P = 141.63 ± 2.01 kg; 50C:50P = 136.25 ± 1.87 kg). These findings suggest that lower levels of fat in milk replacer, formulated with a spray-dried 20% coconut-to-80% palm fat blend, promote solid feed intake and overall performance. A spray-dried blend with a ratio of 35% coconut to 65% palm fat, included at 21% DM, appears to be a more favorable ratio in supporting calf performance.
