  14. Fertilization • N fertilization • 50 – 100 lb N / acre on September

  15. Fertilization Effects of N fertilization on Limpograss nutritive value

  16. Grazing • 50-65 % grazing efficiency • Grazing period: 70-120 d • 0.75 acres / pair

  17. Stockpiled Forage Comparing Limpograss and Bahia + hay winter grazing systems

  18. Grazing • Limpograss (0.75 acres) can substitute approximately 1400 lbs of stored hay (15% waste) • $ 35 /1000 lbs = $ 49.00 • $ 70 / 1000 lbs = $ 98.00

  19. Grazing • 50-65 % grazing efficiency • Grazing period: 70-120 d • 0.75 acres / pair • Plan B

  20. Stockpiled Forages • Plan B: “ BARN FULL OF HAY”

  21. Winter forage • Annual Ryegrass • Cold tolerant varieties • Late maturity, greater spring production • Adapted to most soil types

  22. Annual Ryegrass Table 1. Three years average dry matter yield of annual ryegrass at Overton TX.

  23. Soil testing

  24. Annual Ryegrass • Fertilization program • N-P-K ~ 30 lb/acre – After germination • N ~ 50 lb/acre – Every 6 wks interval

  25. Annual Ryegrass • Planting method

  26. Annual Ryegrass Establishment

  27. Annual Ryegrass VERY IMPORTANT! • Pulling some type of drag behind the seeder and/or rolling helps to cover the seed, firm the seedbed and allow better seed-soil contact

  28. Annual Ryegrass VERY IMPORTANT!

  29. Annual Ryegrass • Nutritive value

  30. Annual Ryegrass • Nutritive value

  31. ADG (lbs/d) Cottonseed meal (lbs/d) Effect of cottonseed meal supplementation or part-time grazing ryegrass on performance of replacement heifers grazing stockpiled Limpograss

  32. Ryegrass ADG (lbs/d) Cottonseed meal (lbs/d) Effect of cottonseed meal supplementation or part-time grazing ryegrass on performance of replacement heifers grazing stockpiled Limpograss

  33. Economics of part-time grazing ryegrass Stocking rate = 3 heifers/acre of ryegrass Cottonseed meal = $200 / ton Grazing part-time ryegrass 12 d /month = 420 lbs cottonseed meal
