  • Dairy herd profitability: effects of milk yield and cost of production on net returns
    Delano, F.D.; Langemeier, L.N. (Kansas Agricultural Experiment Station, 1995)
    Dairy cow herd enterprise records from Kansas Farm Management Association farms over the past 4 years have shown an increase in returns to labor and management from $252 to $355 per cow. Returns for higher milkproducing cows ...
  • Economics of using rbsT
    Smith, J.F. (Kansas Agricultural Experiment Station, 1995)
    As new technologies such as rbST become available to dairy producers, evaluating the profitability of those technologies on individual farms is essential. Costs associated with rbST include purchase of product, feed, ...
  • Improving silage quality
    Bolsen, K.K.; Young, M.A.; Siefers, M.K.; Huck, G.L. (Kansas Agricultural Experiment Station, 1995)
    Results at Kansas State University from over 200 laboratory-scale trials and 28 farmscale trials showed that bacterial inoculants consistently improved preservation efficiency and nutritive value of the ensiled material. ...
  • Inclusion of fat in diets for early lactating holstein cows
    Shirley, J.E.; Scheffel, M.E. (Kansas Agricultural Experiment Station, 1995)
    Twenty-four Holstein cows were used to study the effect of dietary fat on milk production and metabolic traits. Whole cottonseed and tallow were used as fat sources and substituted into the control diet on an ...
  • Management strategies: reproduction
    Smith, J.F.; Stevenson, J.S. (Kansas Agricultural Experiment Station, 1995)
    Despite the negative effects of milk production on some reproductive traits, calving intervals between high- and low-producing groups varied by only 9 days (414 vs 423). First-service conception rates were 8 ...
  • Management strategies: the nutrition program
    Dunham, J.R. (Kansas Agricultural Experiment Station, 1995)
    Reduced milk prices and greater feed costs dictate that dairy farmers carefully manage their nutrition program in order to maintain profitable milk production. Reducing feed cost by feeding less will result in lower ...
  • Observations with heatwatch to detect estrus by radiotelemetry in cattle
    Stevenson, J.S.; Smith, M.W.; Hoffman, D.P; Lamb, G.C.; Kobayashi, Y. (Kansas Agricultural Experiment Station, 1995)
    In Experiment 1, the effectiveness of two estrus-detection methods (visual observation vs radiotelemetric, pressure-sensitive, rumpmounted devices [HeatWatch®]) were compared in heifers. A pressure sensitive ...
  • Performance of cows in the lactation following rbST treatment
    Dunham, J.R. (Kansas Agricultural Experiment Station, 1995)
    The first 305-2×-ME lactation record (after 45 days in milk) projected by the DHI program in 28 cows was not different from their first projected lactation record in a previous lactation in which recombinant bovine ...
  • Performance of lactating cows fed procressed grain sorghum and expeller soybean meal
    Titgemeyer, E.C.; Shirley, J.E. (Kansas Agricultural Experiment Station, 1995)
    Forty-four Holstein cows were used to measure milk production responses to dryrolled vs processed grain sorghum and expeller vs solvent soybean meal (SBM) in a 2×2 factorial arrangement of four treatments. Processing ...
  • Synchronized ovulation with gonadotropin-releasing hormone, prostaglandin F and fixed-time insemination
    Stevenson, J.S.; Kobayashi, Y. (Kansas Agricultural Experiment Station, 1995)
    Summary Lactating Holstein cows and replacement heifers were treated with a novel synchronized ovulation protocol, which involves one fixedtime insemination without heat detection. One injection of GnRH (Cystorelin®) ...
