One-hundred eight (2 to 5 d old) Holstein heifer calves (39.1 � 0.69 kg) from 2 commercial dairies were randomly assigned to 1 of 4 milk replacer (MR) treatments formulated with different levels of Viligen, a blend of short chain fatty acids and prebiotic components, sodium butyrate (SB) to evaluate pre- (d 1 to 42) and post-weaning (d 43 to 56) calf performance and health. The study was conducted between August and December, 2018. All calves were fed a non-medicated 20% CP:20% Fat milk replacer (all-milk protein) fed at 0.28 kg in 2 L of water 2� daily from d 1 to 35 and 1� daily from d 36 to weaning at d 42; supplemented (d 1 to 14) with neomycin sulfate and oxytetracycline at 22 mg/kg BW/d. All calves were fed a medicated (Decoquinate at 45.4 g/ton) texturized calf starter (CS; 18% CP as fed). Milk replacer treatments were as follows: 1) MR without added SB, (CON); 2) MR formulated with 0.24% SB, (SB24); 3) MR formulated with 0.48% SB, (SB48); and 4) MR formulated with 0.72% SB, (SB72). Water and CS were offered free choice from d 1 to 56. Data were analyzed using the PROC mixed procedure of SAS and repeated measures analyses applied where appropriate. There were no differences (P > 0.05) in preweaning, postweaning, or total gains (d 1 to 56) averaging 0.56, 1.12 and 0.70 kg/d, respectively. There was a trend (P = 0.08) of a linear decrease in overall (d 1 to 56) hip height and hip height gain with increasing levels of sodium butyrate fed in the MR. Pre- and post-weaning CS intake was similar (P > 0.05) across treatments averaging 18.1 and 31.2 kg, respectively. There were no differences (P > 0.05) in preweaning, postweaning or overall (d 1 to 56) feed efficiency across treatments averaging 0.61, 0.51 and 0.56, respectively. There were no differences in overall (d 1 to 56) health costs or fecal scores (1 to 4; where 1 = normal, 4 = watery), across treatments, averaging 90 cents and 1.27. Under conditions of this study calves fed a MR formulated with different levels of SB did not affect ADG, gain:feed or health of calves pre- or postweaning.
