Artificial rearing is a common practice for rearing calves from the dairy herd destined for beef production or as replacements for the dairy or suckler herds. One of the major expenses with calf rearing is the cost of the milk. Hence emphasis is placed on early weaning of the calf at 5-7 weeks old and encouraging concentrate intake. With increasing consumer concern over the use of antibiotics in feed, there is greater focus on the use of probiotics or yeast cultures to enhance calf performance. Yeast culture is a fermentation product resulting from the inoculation of grains with Saccharomyces cerevisiae and its growth media. This yeast culture mash is incubated and dried in a manner that preserves all the metabolites and the fermenting activity of the yeast. The objective of this study was to determine the effect of feeding a yeast culture (YC) on the performance of early-weaned beef calves.

Abstract. Forty crossbred (75–87.5% HF) dairy cows were included in a 2 x 2 factorial experiment composed of hand milking (HM) or machine milking (MM), and artificial rearing (bucket feeding, BR) or restricted suckling (RS). Calf suckling and milk feeding was done until 84 days postpartum. Milking was continued until the end of lactation. MM cows had a significantly (p < 0.05) higher daily saleable milk production (SMP) (7.49 vs. 6.97 kg/day), daily total milk production (TMP) (8.60 vs. 7.96 kg/day) and total lactation milk yield (TLMY) (2297.72 vs. 2137.41 kg) than HM cows. The RS cows had a significantly (P < 0.001) higher TLMY (2455.46 vs. 1979.68 kg), annual total milk yield (ATMY) (2277.23 vs. 1970.73 kg), lactation saleable milk yield (LSMY) (2165.90 vs. 1724.64 kg), annual saleable milk yield (ASMY) (2035.21 vs. 1721.17 kg) and daily saleable milk production (SMP) (7.98 vs. 6.47 kg/day) than the BR cows. The MM cows showed a significantly (p < 0.001) higher somatic cell score (SCS) than their HM herdmates throughout the study period. The BR cows exhibited a significantly (p < 0.001) higher SCS than RS cows
