The Matching Game • What is your forage quality? • What are your animal needs? • DO THEY MATCH?? • (What supplements do you still need?)
Spring Lambing on Pasture • When is the highest energy forage? • Vegetative Pasture (2-9”) • Who has the highest energy needs/ when? • Ewe-lamb mothers nursing triplets A PERFECT MATCH! 72% TDN and 18% Crude Protein
Pasture Needed • 1 ewe unit = 1 ewe plus 1.6 lambs Grazing orchardgrass for 7 day grazing period* • Spring regrowth, ¼ acre per “1 ewe unit” • Summer regrowth, ¾ acre per “1 ewe nit” • *assumes 50% utilized, 50% wasted
Last 4 Weeks of Gestation & Early Lactation Ewes, 150 lbs • Pasture, veg or Haylage, veg + no grain (If over 66%TDN,18% C. Protein) • Mature Hay need: 3 lbs grain(24%protein) (50% TDN, 8% C.Protein) • Corn Silage + 1 lbs grain(40%protein) (70% TDN, 8% C. Protein)
Ewes - Maintenance Ration • Grass, headed (58% TDN, 10% C.Protein) • No grain mix needed, but feed free choice: 50% TM Salt and 50% Dicalcium Phosphate Water, most critical feed ingredient.
