The effect of cobalt bullets supplement in the cattle

Abstract

The effect of cobalt bullets therapy on the cattle was determined in seven matched pairs of animals. The cattle used comprised mixed Frisian and 1/4 or ½ Brahman blood. Throughout the experiment the cattle grazed only in cobalt deficient areas. It seems that the cobalt bullets treatment did not affect the growth's rate of animals when compared with the control group. The difference in favor of treated animals did not attain significance. The dressing percentage of the whole carcass was calculated, showing 47 and 46%, for the treated and control groups, respectively. Throughout the thirteen months of the experiment, the mean variation of the body weights was about 16%.
