  • 1. Using grain to improve goat carcass quality and value Susan Schoenian and Jeff Semler University of Maryland Extension
  • 2. I like grain!Thank you for your support of the 2012 pen vs. pasture study.
  • 3. Pen-fed (n=15) Pasture-fed (n=15)• Maintained in dry lot • Maintained on pasture• Free choice grass hay • Pasture only diet Warm and cool season grasses and forbs• Fed grain once per day (4 parts whole barley: 1 part 36% CP pellet) • No supplemental feed
  • 4. Growth rate – average daily gain (ADG) 0.183 vs. 0.149 lbs./day 2.85 lbs. over 84 days
  • 5. Worm status 11 goats dewormed 0 goats dewormed
  • 6. Live grade and carcass yield
  • 7. Meat Quality (last year’s data)Longissimus dorsi had 1.3% intramuscular fat and 23.3% protein. Grams per 100 grams of fat 35.0 Pasture Pen 30.0 b 25.0 20.0 a 15.0 a a a a 10.0 5.0 0.0 Bad SFA Good SFA Good MUFA Palmitic acid Stearic acid Oleic acid 16-0 18-0 18-1, cis-9 Even when there are differences in fatty acid content, the differences are not likely relevant to the human diet.
  • 8. Economics Advantage to pen-fed goats Growth + 2.85 lbs. @ $1.60/lb. = + $4.56 Feed costs $14.05 (pen) - $7.81 (pasture) = + $6.24 Additional profit $4.56 + $6.24 = $10.80/goat $10.80 x 15 goats = $162 total On the other hand The cost of parasite control and any death losses (due to parasites) would have offset the advantage exhibited by the pasture-fed goats.
  • 9. We’d like to repeat the study . . . Why?• Results in 2011 and 2012 were opposite.• We’d like to correct the possible biases in the study. – Equalize groups of goats – Use same scale for weighing• Feed a different ration to the pen-fed goats. – Mixed hay + whole barley• Regardless of the comparison, we’d like to determine if pen feeding can be a viable method for raising market goats.
  • 10. Thank you Maryland Grain Producers!
