Terramycin Supplement for Dairy Calves^{1, 2}

Vermont Agricultural Experiment Station

Abstract

THE value of certain antibiotics in promoting growth in dairy calves is now quite well established. One of the most recent studied is terramycin. Voelker and Cason (1951) fed terramycin to calves at the rate of 30 mg. per 100 pounds body weight. An average gain of 63 pounds was noted for the supplemented calves as compared to 52 pounds for the controls. The length of feeding period is not mentioned. At the rate of 100 mg. daily, seven calves gained 28 percent over the controls. No increase in feed utilization efficiency was observed.

Considerable research has been done on the value of aureomycin for dairy calves. Rusoff (1950), Bartley et al. (1950), Loosli et al. (1951) and Murley et al. (1951) have proved the growth-stimulating properties of aureomycin and its value in checking scours. MacKay, Riddell and Fitzsimmons (1952) found that aureomycin had definite growth promoting effect even in the absence of scours.
