ly decrease during the period that the beef animals are provided supplemental
molasses.

 The results of the 1955-56 experiment studying the value of grass silage
 for breeding cows are shown in Table 2, Grass silage did not produce consistent
 decreases in weight losses or increases in the average weight of calves weaned
 However, there was a definite indication that the extra roughaige intake did have
 a favorable effect upon the reproduction rate of the cows4 as indicated by
 uterine palpation.
