    Rates of embryo survival in lactating dairy cows were assessed in three separate studies. Based on pregnancy diagnoses 27 to 29 days after timed inseminations, survival to days 40 to 50 or day 57, depending on the study, ...
  • Blair, R.M.; Coughlin, C.M.; Minton, J. Ernest; Davis, Duane L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-03-26)
    The primary objective of this study was to determine if embryo survival in gilts and primiparous sows was related to variations in the periovulatory profiles of estradiol- 17β, progesterone, and luteinizing hormone. A ...
  • Tonn, S.; Groothius, P.; Boese, B.; Blair, R.; Davis, Duane L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-03-12)
    The problem of reduced reproductive performance in sows weaned at 5 to 11 days (early weaned) after farrowing was assessed by comparing estrous and embryonic traits in these sows and others weaned at 23 to 31 days ...
  • Davis, Duane L.; Zhang, Z.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-04-15)
    We tested the effects of feeding 4 or 7.4 lb of a complete gestation diet to gilts during days 0 to 2 or 3 to 10 after first detected estrus (day 0) and mating. There was a tendency (P = .11) for the 7.4 lb/day treatment ...

    A multi-location study was conducted using suckled beef cows in Minnesota and Kansas to test the benefit of adding a source of progestin to the Cosynch ovulation synchronization protocol (injections of GnRH, 7 days before ...
  • Rosenkrans, C.F.; Davis, Duane L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-04-15)
    Mixtures of vitamins and amino acids produced detrimental effects on the development of pig embryos. However, addition of three amino acids, phenylalanine, methionine, and isoleuncine, enhanced pig embryo development.
