Intensive Grazing

Intensive grazing, forage varieties comparison

A great deal of work has already been done on the benefits and methods of intensive grazing (confining a relative large number of livestock on a small area for a short period of time). Our ongoing project is attempting to determine which plant varieties, suited to our climate, will respond most favorably to this practice. Eight small pastures were seeded in the spring of 2005 and allowed to become established. During the growing seasons of 2006 & 2007, these pastures were grazed with a small herd of cattle on a rotational basis with each pasture being grazed for three days and allowed to rest for twenty-one days before being grazed again. Forage and fecal samples were taken from each pasture and analyzed to determine quantity and quality of the forage and potential rates of gain for the cattle. Results from the first two years have been compiled by the local Natural Resource Conservation Service and shared with area producers.

The Goals and Objectives of the project are to:

  • Showcase different species for irrigated pasture
  • Monitor protein and energy through the growing season for different species by using fecal analysis
  • Monitor re-growth potential for different species
  • Monitor production for different species
  • Showcase intensive grazing on irrigated pastures
  • Meet producers cattle production goal of 2.5 lbs/day

  • Actual gain for the steers in 2006 = 2.56 lbs/day
  • Actual gain for the steers in 2007 = 2.97 lbs/day
  • A difference of .41 lbs/day
  • Gained 11,037 lbs on 25.6 acres in 2007
  • At $1.00/lb, gross income was $431/acre
