  • Camelids are economically important production animals in many areas of the world. Early pregnancy loss is a major cause of reproductive inefficiency. Pregnancy maintenance depends on a timely signaling mechanism called maternal recognition of pregnancy (MRP). This mechanism is not well characterized in camelids. The work presented in this thesis is part of a larger research program to study early embryo development and MRP, as well as factors involved in early pregnancy loss. more »
  • The male camelid has a tremendous impact on the reproductive performance and genetic improvement of a herd. Despite this, scientific reports on the male in the published literature remain scarce. Approximately only one paper is published on the male for every six papers published on reproduction in the female. In recent years, interest in the male has increased, particularly in semen and its use for artificial insemination. This chapter covers the reproductive physiology of the male with regard to the development of testicles, the disappearance of the penis–prepuce attachment, and the concentrations of testosterone. Finally, the spermatogenic function of testicles, including spermatic reserves, and the relationship between semen characteristics and fertility of the female are reviewed. more »

  • Good quality grasses (the pasture is always best), hays and other good “rumen foods” are what the camelid physiology is built for. The major issue we see on farms is overfeeding and fat animals. more »
  • Here is the physiology of “rye grass tetany” or “rye grass staggers” and then you can decide how to control your forage choices. The confusion is that we are talking of at least two separate issues, but with similar symptoms. more »
