Mitigation of summertime boar infertility by evaporative and conductive cooling
(University of Missouri--Columbia, 2018)
[trademark] Temperature Implant, Data Sciences International; St. Paul, MN): one implanted between the peritoneum and the body wall (core temperature); the other sutured between the testicular tunics (testicular temperature). The initial selection for the most effective...
Effects of heat stress on reproduction and productivity of primiparous sows and their piglets' performance
(University of Missouri--Columbia, 2009)
.75 vs. 3.12 kg; P [less than] 0.001). Total born (11.7 pigs), piglet birth weight (1.46 kg) and total weaned (10.3 pigs) were similar, but weaning weight was greater for TN sows (6.21 vs. 5.76 kg; P [less than] 0.053). Weaning to estrus interval (4.70 d...
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 ...
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 PG-600 nor BE (control). PG...
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 ...
