September Tips for Beef Cattle and Forage Producers

September Tips for Beef Cattle and Forage Producers



Spring Calving Herds

  • Cow herd performance is an opportunity to use production data to aid in replacement heifer selection or cull cows due to poor performance. A herd performance test involves weighing cows and calves, frame and muscle scoring calves and body condition cows.
  • Walk through your cattle working facilities and take note of repairs and maintenance before fall weaning. Test all weak spots. These are supposed to be “working” facilities not “work-out” facilities. Facilities should be maintained for your safety as well as safety for your cattle.
  • Start making plans for weaning calves. Retained ownership can often increase gross income, but to be profitable, cost of feed cannot be too excessive. Hay and supplement based programs are more costly than pasture and supplement programs, so good fall pasture management is important.
  • Consider fence line weaning suckling calves. This reduces stress on the cows and calves. In addition calves continue to gain weight and respiratory disease is greatly reduced compared to conventional weaning. Training cattle to respect electric fencing prior to weaning can facilitate the weaning process. Fence line weaning also allows high-quality pastures to be used as weaning facilities in place of dusty drylots.
  • Implement a precondition program. Precondition programs include weaning calves at least 45 days to sale or according to the requirements of the specific preconditioning program, castrating bull calves, dehorning if necessary and a vaccination program. Preconditioned calves will sell for higher selling price.   Remember to follow BQA guidelines when giving vaccinations.
  • Pregnancy tests all cows. Cull all open cows and cull all cows with physical problems such as bad eyes, poor udders, lameness, missing teeth, etc.
  • Select replacement heifers based on pre-weaning performance and phenotypic expression. Also select heifers that were born early in the calving season.
  • Vaccinate heifers for brucellosis.
  • Forage test and plan for winter feeding program.

Fall Calving Herds

  • Cows should be calving. Check cows often throughout the calving season. Check first calf heifers more often.
  • Vaccinate replacement heifers 30 to 60 days before the breeding season.
  • Evaluate and select sires for breeding season.
  • Take care of newborn calves; dip navel, ear tag, castrate bull calves, etc.
  • Forage test and plan for winter feeding program  

Forage/Grazing Management Tips

  • Check pastures regularly for fall armyworms. Armyworms prefer grasses such as bermuda, native grasses and newly seeded grasses (winter annuals or fescue). For more information on armyworms go to
  • Plant small grains such as rye or wheat.
  • Winter annual legumes such as crimson clover, arrowleaf clover, and hairy vetch potentially provide multiple benefits, including grazing and improving soil fertility. Plant them in mid to late September for northern Arkansas. These legumes can be no-till drilled into warm-season grass stubble (bermudagrass) in early October.
  • No-till drills need to be kept clean and in good working order to plant at consistent depth and seeding rates.
  • Be on the alert for prussic acid poisoning when grazing johnsongrass, sorghum-sudan hybrids, grain sorghum or sudangrass. 


  • Stockpile fescue for winter grazing.
  • Clip or graze fescue pastures to 4” stubble by September 1 and fertilize with 50-60 lbs. /acre of nitrogen by mid-September.
  • Defer grazing until late November or early December.
  • Strip-grazing will yield twice as many grazing days as compared to giving access to the whole pasture. 

Bermudagrass Winter Pasture

  • Prepare bermudagrass pastures for interseeding ryegrass or small grains to use as winter pasture.
  • Graze bermuda to a 2-3” height in September.
  • Plant winter annuals with no-till drill or broadcast/drag in early October in bermuda.
  • In bermuda, plant small grain at 100-120 lbs. /acre; plant ryegrass at 20-25 lbs. /acre.
