Over a 1 O-year span, grazing intensities of 35, 49, and 57% use of the current year’s growth did not affect total forage yields on southern pine range. However, yields started to decline when the young pines were about age 9. Calf crops were highest from cows grazing lightly and lowest with heavy stocking; calf weaning weights and daily gains did not differ because of stocking rates. Highest total returns per calf were received from cows grazing lightly. Greatest returns per acre were from herds grazing heavily. Cattle Management Cows were typical crossbred native piney-woods cattle. The majority showed evidence of Brahman breeding while the remainder were mixtures of other beef and dairy breeds. Purebred bulls (Hereford or Shorthorn) were mated with the native cow herds for December through March calving; calves were weaned and marketed in mid-August when about 210 days old. Southern pine forests provide substantial quantities of forage after timber harvest and until reforestation appreciably shades out the understory plants. Grazing varies from heavy to light, but livestock responses to grazing intensities have not been well defined. This research assesses effects of grazing regimes on the production efficiency of beef breeding herds. Findings pertain to some eight million acres comprising the western portion of the longleaf-slash pine type, where bluestem grasses predominate in the understory. |
