1 Annual Ewe Management Program (Winter Lambing)

2 I. Ewe Production Stages Flushing:August 1 to August 15 Breeding:August 15 to October 7 Early Gestation:September 7 to December 26 Late Gestation:December 26 to January 23 Average Lambing Date:January 23 Lactation:January 23 to March 24 Average Weaning Date:March 24 Post-Weaning:March 24 to April 3 Maintenance:April 3 to August 1

3 II. Nutritional Flushing (14 days) A. Minimally Intensive. 1.Average grass pasture. 2.No concentrate.

4 II. Nutritional Flushing (14 days) A. Moderately Intensive. 1.Turn teasers in. 2.Replace with fertile rams. 3.Supplement existing pasture. 4.Move to new OG or BG pasture. No grain.

6 II. Nutritional Flushing (14 days) A. Each mgnt. level begins 2 weeks before and continues 3 weeks into breeding. B. ADG = 0.2 to 0.25 lb/hd/d. C. Leave in 2.0 to 2.5 BCS. D. Can’t flush if BCS > 3.0 E. Mineral, water, shade.

7 III. Breeding (53 days) A.Leave ewes in same area for 7 to 10 days after ram removal. B.Leave in 2.0 to 2.5 BCS. C.Ewe: ram. Mature = 35 to 50:1. Yrlg = 20 to 35:1. Lamb = 15 to 20:1. D. Mineral, water, shade.

8 IV. Early Gestation (110 days) A.Enter in 2.0 to 2.5 BCS. B.ADG = 0.07 lb/ewe/d. C.Leave in 3.0 or less BCS. D.Check pregnancy. E.Cull opens. F.Shear, FAMACHA, trim hooves.

9 IV. Early Gestation (110 days) A.Nutrition options. 1.Scavengers. 2.Stockpiled grasses. 3.Turnips. 4.No pasture. (a)3-5 lb low-quality hay in barn. (b)Big bales (low-quality) in pasture area. B.Mineral, water, shade. C.Quality of feed unimportant if quantity is adequate.

10 V. Late Gestation (28 days) A.Enter in 3.0 BCS. B.Check FAMACHA and BCS. C.CDT vaccination. D.Begin to feed 1.0 lb grain/ewe/d. 1. 1x/d on Dec Pasture, turnips, hay.

11 V. Late Gestation (28 days) A.Move ewes to barn on Jan. 3. B.Ration 1. OG hay (EV) = 3.3 lb/ewe/d. Shelled corn = 1.2 lb/ewe/d. C.Ration 2. Alfalfa hay (MB) = 4.1 lb/ewe/d. Shelled corn = 1.0/ewe/d. D.Mineral, water. E.ADG = 0.5 lb/ewe/d. F.BCS at lambing = 3.5 to 4.0.

12 VI. Lambing A.“Up close”pens. B.Move to jugs. C.Process lambs. D.Weigh, record, iodine navel. E.Remove mucal plug in teat. F.Water for ewes first 24 hours.

13 VI. Lambing A.Check ewes/lambs every 2 hours. B.3.0 to 5.0 lb grass hay/ewe/d. C.Stay 24 hours up to 2 to 5 days. D.Move to nursery pen – process lambs.

14 VII. Lactation (60 days) A.De-worm as ewes leave jugs. B.Leave in BCS of 1.5 to 2.0. C.Feed for milk, not BCS. D.Mineral, water.

19 VIII. Post-weaning (10 days) A.Remove grain. B.Reduce hay/pasture. C.No feed, mineral or water for 48 hours. D.After 48 hours, provide water and mineral. E.Graze 2 hours/day for 3 days. F.Gradually graze full-time.

20 IX. Maintenance (118 days) A.Palpate udders, review records, cull after 1 month. B.Shear keepers. C.FAMACHA, BCS monthly. D.De-worm 4’s and 5’s. E.Trim feet, foot bath. F.Vaccinate for Vibrio and EAE. G.De-worm before flushing. H.Rotate pastures, mineral, water, shade.

21 Annual Ram Management Program (Winter Lambing)

22 I. Nutritional Flushing (14 days) A. Minimally Intensive. 1.Grass pasture. 2.No supplement. 3.De-worm fertile rams.

23 I. Nutritional Flushing (14 days) A. Moderately Intensive. 1.De-worm teasers/fertile rams 2.Replace teasers on August Manage like ewes.
