Evaluation and development of early pregnancy diagnosis in dairy cattle
(University of Missouri--Columbia, 2018)
Early chemical pregnancy tests for use in dairy cattle are necessary to aid in reducing the costs associated with days the animal is not pregnant. Identifying non-pregnant dairy cattle sooner would allow for efficient treatments and improve decision...
Transgenerational effects of in utero heat stress on reproduction in pigs
(University of Missouri--Columbia, 2017)
(GHS n=23; GTN n=25) were moved to the University of Missouri Swine Teaching Farm to farrow at approximately day 114 of gestation. No differences were observed between GHS and GTN females at the 8th week of gestation. Similarly, no differences were...
Effects of heat stress on reproduction and productivity of primiparous sows and their piglets' performance
(University of Missouri--Columbia, 2009)
Heat stress (HS) produces seasonal infertility in sows and decreases reproductive efficiency. Sows were exposed to HS during a production cycle (gestation [gest], lactation [lact], and breeding) to examine productivity. ...
Characterization of progesterone receptor (PGR) mRNA and protein isoforms in the endometrium of cyclic and pregnant pigs
(University of Missouri--Columbia, 2010)
in endometrial tissue from cyclic (days 0, 5, 7.5, 10, 12, 13, 15, 17) and pregnant (days 10, 12, 13, 15, 17) pigs. Isoform PGR-B mRNA had a tendency to be greater on d 0 and d 5 and decreased on d 7.5 and d 15 (P < 0.10). Combined PGR-AB mRNA was constitutively...
