Grain for Steer on Good Spring Pasture

A 66-day grazing period in the spring of 1959 showed little benefit from grain to steers on grass. Steers which received 4 pounds daily of equal parts ground barley and oats gained 3.06 pounds per day, while unsupplemented grass produced 2.95 pounds gain per day. The trial was repeated in 1960, using 4 pounds daily of ground barley as the supplement. Daly gains for 73 days of grazing in 1960 were 2.73 pounds with grain and 2.17 pounds without grain. In an effort to determine if this large increase in gain from grain on pasture would hold during dry-lot finishing, the two lots of steers were placed in dry lot and fed the same ration after July 14. Results of the trial are presented in Table 12.
