Effect of high peroxide value fats on performance of broilers in normal and immune challenged states
(University of Missouri--Columbia, 2009)A series of trials were conducted in order to determine the effects of high peroxide value fats on performance of broilers in normal and immune challenged states from 0-49 days of age. In the first experiment, birds were ... -
Effect of RU486, a progesterone antagonist, on uterine progesterone receptor, embryonic development and ovarian function during early pregnancy in pigs
(University of Missouri--Columbia, 2009)Progesterone (P4) down-regulates the progesterone receptor (PGR) exclusively within the epithelium of the pig uterus near d 8 of the estrous cycle and pregnancy. How P4 down-regulates the PGR is not understood but is ... -
Effects of feeding a fumonsin (FB[subscript 2]) naturally contaminated corn at various levels, with and without 2 adsorbents on the growth performance, blood, and liver chemistry of nursery pigs
(University of Missouri--Columbia, 2009)Three studies were conducted to determine the effects of diets containing various concentrations of fumonisin FB1 supplied by naturally contaminated corn with and without 2 adsorbents on nursery pig performance. Use of ... -
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 low crude protein diets with amino acid supplementation on broiler performance in the starter period
(University of Missouri--Columbia, 2009)A series of experiments were conducted to examine the effects of feeding low crude protein (CP) corn and soybean meal diets with crystalline amino acid supplementation to broilers from 0-3 weeks of age. It was hypothesized ... -
Progestin regulation of follicular dynamics in beef cattle
(University of Missouri--Columbia, 2009)Progestins, such as melengestrol acetate (MGA) and Controlled Internal Drug Release (CIDR), can inhibit ovulation and synchronize estrus in cattle. However, long-term MGA treatment, in the absence of a corpus luteum, results ...
