Multiple Species Grazing In OklahomaDave Sparks DVMOklahoma State UniversityExtension Food Animal Qualityand Health Specialist
Why Multiple Species Grazing?• Two income stream from one set of fixed assets (land and equipment).• Helps in controlling internal parasites of both species, but especially goats.• Overlap of species grazed/browsed is variable, but increases overall stock rate.• Diversification of livestock program• Multiple income times aids cash flow.
Famacha•Used to select goats that actually need worming•Based on the fact that Barber Pole Worm kills by sucking blood•Evaluates the degree of anemia if present•80% of the parasites are in 20% of the goats•Slows the development of dewormer resistant•Saves money on drug purchase
Washington County 2007 - 2008• Project set up with two cooperators who currently grazed both cattle and goats, but not together.• County extension educators from Osage, Washington, and Nowata counties.• Area and State specialists in herd health, range agronomy, entomology, and pest management.• Utilized 200 acres of open native range.
Washington County 2007 - 2008• Divided into 3 sections, similar in forage quantity and forage type.• Stocked one pasture with goats only, one with cattle only, and one with cattle and goats combined.• Bob Woods, area agronomist, set stocking rates in total lbs. of livestock, based on forage availability. Cooperators and county educators then translated stocking weights into cattle and goat numbers.
2008 Eye Score 5’s Washington County EYE SCORE 5 Goats Only: 10% of all eye checks Mixed Goats: 6% of all eye checksGOATS ONLY MIXED GOATS & CATTLENever Wormed 24% Never Wormed 31%Wormed Once 31% Wormed Once 36%Wormed 2-3 Times 30% Wormed 2-3 Times 19%Wormed 4-5 Times 15% Wormed 4-5 Times 14%Wormed Every Time 8% Wormed Every Time 6%The biggest change is in the goats wormed 2 – 3times. These goats are neither real strong or realweak on parasite control immunity. This is thegroup most influenced by pasture contamination.
Muskogee County 2008• The How and Why of the Project• Multiple Species Grazing Project Started in Washington County in 2007• Utilized tall grass native range• Led to questions for smaller acreage, intensive grazing of introduced grasses• History of the property• Joint Venture – OSU Extension and Kerr Center for Sustainable Agriculture
Obstacles to Overcome• partitions for rotational grazing• fences• water availability• soil testing and amendment• what kind of cattle? what kind of goats?• setting stocking rate for sustainability• herd health program• predator control• parasite control program• marketing cattle and goats

Pasture Evaluation• Bob Woods used step point transect method to determine pasture composition at beginning and end of the growing season.• All paddocks increased in grass, decreased in legumes and brushy species, while staying about the same for forbs.• In both trials Bob used Web Soil Survey to suggest stocking rates and at the end of the season to recommend adjustments. In both trials he recommended stocking rate of cattle go up.
