Transgenerational effects of in utero heat stress on reproduction in pigs
(University of Missouri--Columbia, 2017)
Seasonal infertility caused by high ambient temperatures and humidity during the summer months can have negative effects on the reproduction of female swine. These conditions may cause heat stress leading to large economic ...
Estrus induction and maintenance of cycles in gilts with PG-600 and boar exposure
(University of Missouri--Columbia, 2007)
This study looked at the efficacy of PG-600 and boar exposure to induce and maintain cycles. Gilts received one of four treatments: PG-600, weekday 10 min full physical contact boar exposure (BE), PG-600+BE, and neither ...
Arachidonate 15-lipoxygenase and ubiquitin as potential fertility markers in boars
(University of Missouri--Columbia, 2004)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This study was performed to determine whether using high power microscopic analysis and two putative biochemical fertility markers, 15-lipoxygenase ...
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. ...
Effects of Artemisia afra and Artemisia absinthium on fertility of male mice exposed to increased ambient temperatures for 24 hours
(University of Missouri--Columbia, 2010)
Males exposed to elevated temperatures display a decrease in reproductive performance resulting in decreased profit for producers. The use of herbs to alleviate the effects of heat in tropical countries has been documented ...
