Varying calcium levels in the range of 0.15 and 0.60% and phosphorus in the range of 0.37 and 0.79% in an all-concentrate diet for finishing steers had no effect on weight gains, feed consumption, blood calcium and phosphorus or bone ash. A 19% (significant P<.05) thinner fat thickness over the I. dorsimuscle was associated with the feeding of 0.60% calcium when compared with the 0.15% calcium treatments. Two sources of calcium, ground limestone and dicalcium phosphate, were used and no significant difference between sources was observed for any of the criteria. The thinner fat thickness was accompanied by a significant (P<.01) increase in the concentration of the 16:0 fatty acid, but the effect on carcass fat did not appear to be related to variations in proportions of volatile fatty acids produced in the rumen. Dressing percent, grade, area of the I. dorsimuscle and marbling were not affected by treatment. |
