    Time requirements for loading a manure spreader and traveling to and from the field varied from 20 to 30 min per load. However, standardizing the data showed that 5 to 7 min were required per 1,000 gal (9,000 lb). ...
  • Stokka, G.L; Smith, J.F.; Dunham, J.R.; Van Anne, T. (Kansas Agricultural Experiment Station, 1996)
    Foot problems are major concerns for dairies, and care should be taken to avoid promoting them. Preventive measures, with the aid of a veterinarian, must be followed if the problem is expected to be controlled. ...
  • Harner, Joseph P.; Smith, J.F. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2009)
    Existing blueprints were used to estimate land requirements for new dairy facilities. The average land requirement for constructing a new dairy complex with freestall housing and a new parlor is 915 ft2 per lactating ...
  • Olson, Jerry (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2003)
    Disease causing Leptospira can be placed in one of two broad categories for common domesticated mammals: They are either hostadapted or incidental strains. The four incidental serovars of Leptospira that are pathogenic to ...
  • Eicher-Pruiett, S. D.; Morrill, J. L.; Blecha, Frank; Chitko-McKown, C. G.; Anderson, N. V. (Kansas Agricultural Experiment Station, 1991)
    Forty-four Holstein calves were fed milk replacers with varied concentrations of vitamins A and E from 3 to 45 d of age to determine their effects on concentrations of plasma vitamin A (retinol and retinyl palmitate) ...
  • Eicher, S.D.; Morrill, J.L.; Blecha, Frank (Kansas Agricultural Experiment Station, 1992)
    Blood neutrophils and pulmonary alveolar macrophages isolated from calves at 3 and 6 wk of age were cultured in medium without added vitamins or supplemented with vitamin A, vitamin E, vitamin A and vitamin E, or ...
  • Call, Edward P. (Kansas Agricultural Experiment Station, 1993)
    The current economic situation dictates that dairy producers use all available tools and resources to maximize efficiency. Yearly milk yield is the most reliable predictor of profitability. Because the genetic base ...
  • Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2009)
    In Experiment 1, lactating dairy cows (n = 1,230) in 6 herds were treated with 2 injections of prostaglandin F2α (PGF2α) 14 days apart (Presynch), with the second injection administered 12 to 14 days before the onset of a ...

    Three experiments were conducted to characterize lysine fermentation by Fusobacterium necrophorum, a ruminal bacterium that is known to degrade amino acids. In Experiment 1, 7 strains of Fusobacterium necrophorum were ...
  • 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)
