Age as a factor in animal breeding
(University of Missouri--Columbia, 1911)
Many breeders believe in the evil effect of early reproduction. It is said that early marriage has led to the degeneracy of many nations. The domestic animals are national assets and their preservation, like the conservatives ...
Evaluation of the 7 and 7 synch protocol for control of the estrous cycle among beef cows prior to fixed-time artificial insemination with sex-sorted or conventional semen
(University of Missouri--Columbia, 2021)
at 66 or 72 h after administration of prostaglandin F2[alpha] (PG). Estrus was synchrized using the 7 and 7 Synch protocol, which consists of administration of PG (500 [mu]g cloprostenol) and insertion of an intravaginal progesterone-releasing insert...
DNA methylation in the early porcine embryo
(University of Missouri--Columbia, 2007)
, parthenogenetic activation, and somatic cell nuclear transfer. An extension of this rationale is that the methylation profiles of in vivo-matured oocytes or very early in vivo-produced embryos may be the optimal target for the methylation profile of donor cells...
Studies of ruminant digestion, ecology, and evolution
(University of Missouri--Columbia, 2008)
This thesis examines ruminant digestion, ecology, and evolution, particularly where they can improve livestock production systems. We performed an experiment that estimated ruminal in situ degradation parameter values of ...
The effects of elevated temperature on preimplantation-stage porcine embryos
(University of Missouri--Columbia, 2006)
It was the objective of these experiments to more fully characterize the biochemical and developmental responses of in vitro-produced preimplantation stage porcine embryos to elevated temperatures. In vitro fertilized (IVF) ...
