  • DeLano, F.D.; Langemeier, Michael R. (Kansas Agricultural Experiment Station, 1994)
    Actual records of dairy cow herd enterprises from Kansas Farm Management Association farms over the past 4 years have shown an increase in returns over variable costs from $17,900 to $27,000 per farm for a 100-cow dairy ...
  • Chenoweth, P.J.; Smith, J.F. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    Natural service (NS) bulls are widely used on large dairy farms despite the wellproven genetic progress achievable through AI. Producers may choose to use NS bulls for a variety of reasons that are discussed below. ...
  • Smith, J.F.; Stevenson, Jeffrey 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 ...
  • 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 ...
  • Shirley, John E. (Kansas Agricultural Experiment Station, 1994)
    The primary focus of the dairy industry in Kansas has been the milking herd. However, dairy heifer replacements and dairy steers offer income opportunities that have been largely ignored by some Kansas dairy producers. ...
  • Shirley, John E. (Kansas Agricultural Experiment Station, 1988)
    Progress in the dairy industry over the past 30 yr can be defined as a movement toward fewer farms, more cows per farm, fewer total cows, more milk per cow, a gradual decline in total annual milk production from 1950 ...
  • Shirley, John E. (Kansas Agricultural Experiment Station, 1990)
    The decade of the 1980s was a transition period for the Dairy Industry in the United States. The decade began with a large milk surplus and low prices and ended with milk shortages and record high prices. The dairy ...
  • Dunham, J. R. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 1997)
    Comfortable cows are contented cows. However, cows may be comfortable in their environment but also experience some discomfort because of the nutrition program. A good nutritional management program will improve ...
  • Strahm, T.D.; Harner, Joseph P.; Key, David V.; Murphy, James P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Nine primar,y lagoons and solids storage basins were sampled on Kansas dairies using flush systems. These samples were analyzed for nutrient content of wastewater and sand manure. The manure moisture content in ...
  • Harner, Joseph P.; Murphy, James P. (Kansas Agricultural Experiment Station, 1994)
    Kansas environmental regulations require dairy producers with more than 300 animal units (215 mature cows at 1,400 lb, or equivalent weight) to be able to store the manure scraped from freestalls, lots, alleys, and ...
  • Smith, J.F.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Mastitis is the most costly health concern in the dairy industry today. Annual losses have been estimated at $180 to 185 per cow. Based on this figure, annual losses for Kansas producers may exceed $15 million. Nationally, ...
  • Vargas, C. F.; Reinhardt, Christopher D.; Firkins, J. L.; Bradford, Barry J. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 2012)
    A meta-analysis was performed to determine the possible effects of dietary sugar on feed intake and milk production in lactating dairy cattle. The database used in this analysis included 18 treatment comparisons frozm ...
  • Park, A.F.; Titegemeyer, E.C.; Cochran, R.C.; DeFrain, J.M.; Ferdinand, E.E.; Johnson, D.E.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    We used four ruminally fistulated, multiparous, pregnant Holstein cows to measure changes in concentrations of plasma metabolite as the dairy cow transitions from one lactation to the next. Diets consisted of typical ...
  • Roberts, H.A. (Kansas Agricultural Experiment Station, 1986)
    Milk consumption is influenced by the quality and flavor of the milk a person drinks. Today the consumer evaluates milk solely on its taste and keeping quality. Since the flavor of milk cannot be improved after it leaves ...
  • Stevenson, Jeffrey S.; Call, Edward P. (Kansas Agricultural Experiment Station, 1986)
    Diagnosing pregnancy in dairy cattle is an essential part of good management. The objective of this procedure is not to identify pregnant cows, but to identify the nonpregnant cows, those that become the breeding ...
  • Julstron, L.F.; Schmidt, Karen A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    Packaged, reduced-fat milk was subjected to a 20 min/day temperature cycle during a 7-day refrigeration period to determine the ef-fect on milk quality. Temperature cycling did not affect the compositional or microbial ...
  • Dunham, J.R. (Kansas Agricultural Experiment Station, 1996)
    Milk urea nitrogen (MUN) analyses can be used to evaluate the nutritional status of dairy herds and for fine tuning the feeding program. MUN values >18 mg/100 ml indicate that dietary protein is being wasted and feed ...
  • Blevins, C.A.; Aberle, J.J.; Hensley, B.A.; Tiffany, S.M; Shirley, John E.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    The objective of this study was to determine how milking frequency, estradiol cypionate (ECP) postpartum therapy given at 1 week after calving, and biweekly bovine somatotropin (bST) administration alter lactational ...
  • Dunham, J.R.; Call, Edward P. (Kansas Agricultural Experiment Station, 1988)
    Thirty Milking Management Clinics have been conducted at various on-farm locations. The clinics have demonstrated that good milking techniques can result in an additional 1891 lb milk yield/cow in a 10-mo lactation and ...
  • DeFrain, J.M.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    The efficiency of feedstuff utilization by ruminal microorganisms and the cow’s genetic ability to convert feed nutrients into milk and milk components are major factors that influence the profitability of a dairy herd. ...
