  • Aflatoxin in milk and dairy products
    Ikins, W.G. (Kansas Agricultural Experiment Station, 1986)
    Aflatoxins are toxic compounds that are produced by certain strains of molds, namely, Aspergillus flavus and Aspergillus parasiticus. These molds may invade stressed crops in the field or proliferate in improperly stored ...
  • Availability of calcium in dairy and other human foods
    Jeon, I.J. (Kansas Agricultural Experiment Station, 1986)
    In 1985 the annual sales of dairy products on the average grew 3.3%, and is expected to grow 6.4% in 1986, according to the U.S. Department of Commerce. This positive growth was attributed in part to increased consumer ...
  • Bypass protein-Theory and concept
    Harmon, D.L.; Nagaraja, T.G. (Kansas Agricultural Experiment Station, 1986)
    The ruminant animal has the unique advantage of microbial digestion in the rumen. This relationship between host animal and microbial population presents some unique advantages and disadvantages to the animal in terms ...
  • Dairy replacement heifer nutrition
    Morrill, J.L. (Kansas Agricultural Experiment Station, 1986)
    Proper nutrition and management are necessary to provide adequate numbers of healthy herd replacements. Satisfactory heifer programs must take into consideration care of the dam and characteristics of the newborn calf, ...
  • Effect of buffers and supplemental potassium in diets of early-weaned calves
    Jordan, K.J.; Morrill, J.L.; Reddy, P.G.; Higgins, J.J.; Anderson, N.V. (Kansas Agricultural Experiment Station, 1986)
    Potassium chloride added to the prestarter and/or potassium bicarbonate added to the starter fed to early weaned calves helped maintain normal blood alkalinity and normal levels of blood gases, and resulted in a trend ...
  • Effect of milk intake and method of weaning on calf performance and stress in an early-weaning program
    Flynn, P.; Reddy, P.G.; Morrill, J.L.; Stevenson, J.S. (Kansas Agricultural Experiment Station, 1986)
    Feeding milk at 8% of birthweight and gradual weaning resulted in the most consistent increases in weekly weight gain, highest overall weight gain, and greatest increases in dry feed consumption during an 8-wk trial ...
  • Effect on ruminal lactic acid utilization and lactic acid-utilizing bacteria
    Miller, G.W.; Nagaraja, T.G. (Kansas Agricultural Experiment Station, 1986)
    The effect of diet on in vitro lactic acid utilization rate and counts of lactic add-utilizing bacteria was determined in ruminally cannulated steers. The steers were adapted to an alfalfa diet and gradually switched to ...
  • Evaluation of high-energy calf starter for early-weaned calves
    Carinder, W.H.; Reddy, P.G.; Morrill, J.L. (Kansas Agricultural Experiment Station, 1986)
    An experimental calf-starter diet containing roasted whole soybeans, buffer and dehydrated alfalfa pellets was compared with a conventional calf starter for young calves on an early-weaning program. Overall means for ...
  • Feed additives
    Dunham, J.R. (Kansas Agricultural Experiment Station, 1986)
    Feed additives are ration ingredients used in relatively small amounts to fortify certain nutrients or to affect a specific physiological function. The decision to include any additive should be based upon the economic ...
  • Field applications of exogenous hormones- Gonadotropin and Prostaglandin
    Call, E.P. (Kansas Agricultural Experiment Station, 1986)
    Prostaglandin F2α (PGF) and gonadotropin-releasing hormone (GnRH) have provided new dimensions in resolving certain reproductive maladies. Effective when used properly, these hormones have the advantage of mimicking the ...
  • Forage analysis using near-infrared spectroscopy (NIRS)
    Harbers, L.H. (Kansas Agricultural Experiment Station, 1986)
    It has been over 15 years since an analytical instrument was developed that could rapidly determine the concentration of organic compounds from the spectra produced by the bonding between carbon and certain molecules. ...
  • Influence of multiple daily injections of oxytocin on reproductive and milk characteristics of postpartum dairy cows
    Stewart, R.E.; Stevenson, J.S. (Kansas Agricultural Experiment Station, 1986)
    Release of oxytocin at the time of suckling or milking may delay onset of estrous cycles in postpartum cows. Twenty lactating Holsteins were used in this study to determine if multiple daily injections of oxytocin would ...
  • Introducing a computer feeding system at various lactational stages for dairy cows
    Kube, J.C.; Shirley, J.E.; Frantz, K.D.; Stevenson, J.S. (Kansas Agricultural Experiment Station, 1986)
    Lactating dairy cows were introduced to a computer feeder in early (≤120 days in milk or D.I.M.), mid (120-220 D.I.M.), and late (>220 D.I.M.) lactation. Cows in the mid- and late-lactation groups adjusted quicker and ...
  • Is a computer feeder necessary in the dry lot cow?
    Kube, J.C.; Shirley, J.E.; Frantz, K.D. (Kansas Agricultural Experiment Station, 1986)
    Springing heifers and dry cows were introduced to a computer feeder either 2 wk before their estimated freshening date or at calving. There was no significant difference in milk production, percentage milk fat, percentage ...
  • Milk flavor quality on the farm
    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 ...
  • Milk progesterone kits: On-farm use
    Stevenson, J.S.; Call, E.P. (Kansas Agricultural Experiment Station, 1986)

  • Overview: Developing a high profit herd
    Shirley, J.E. (Kansas Agricultural Experiment Station, 1986)
