Suggested pasture supplemental feeding programs

 (1) Replacement heifers.

 (a) On organic soil, and on grass-legume pastures on mineral soil -
 3 to 5 pounds daily of a high energy feed, with a 12 to 14 percent
 crude protein during late fall and winter.

 (b) On sandy soil same feeding schedule of a high-energy supplement
 having a minimum of 18 to 20 crude protein, or 1 pound of a 40
 percent supplement plus 3 to 4 pounds of a high energy feed.

 (2) Stockers. The type of program followed will affect the supplemental
 feeding program required. It is suggested that weanling steers should
 not be on inventory for more than 12 months and yearling steers for
 not more than 6 to 8 months. If the entire period is spent on pasture
 it will be necessary to supplement pasture with 0.8 to 1.0 percent of
 the animals weight as supplemental feed. On good pasture on organic
 soil and grass-legume mixtures on sandy soils, protein level need not
 exceed 12 percent. On grass pastures on mineral soil it may be
 necessary to increase the protein content of the supplemental feed to
 approximately 18 to 20 percent during fall and winter months. The
 supplemental feed should be high in total digestible nutrients.

 (3) Brood cows.

 (a) Organic soil feed 3 to 5 pounds of a high energy feed daily
 from November 15 until bulls are removed. If bulls are left in
 all year feed from approximately November 15 to April 15. The
 protein level need not exceed 10 percent. If a supplement is
 used on grass-legume pastures on sandy soils the same type is
 suggested.

 (b) Sandy soils, without legumes feed 3 to 5 pounds daily of a 18
 to 20% supplement, or 2 to 3 pounds of a high energy feed plus
 1 to 2 pounds of a 40 percent protein supplement.
