Implications of ovarian and uterine maturity evaluated in replacement heifer candidates
(University of Missouri--Columbia, 2021)
days after the end of the breeding season. The incidence of disparate ovarian score (OS) and uterine score (US) was 33.7 percent (n = 158/469) in Experiment 1 and 16.3 percent (n = 3,622/22,174) in Experiment 2. Heifers assigned a RTS of less than 3...
Regulation of fetal brain development in short versus long lived mice
(University of Missouri--Columbia, 2022)
result, most Cav-1- null mice die within a year. Gene expression in bulk brain tissue as well as single cells were analyzed in the Cav-1-null fetal brain compared to the wildtype (WT). The results of this study showed that lack of Cav-1 leads to extensive...
Effects of the bovine slick mutation on heat stress responses and hair growth in mice
(University of Missouri--Columbia, 2020)
The bovine slick mutations result from more than one allele variant causing a slick hair phenotype and improved thermotolerance to elevated ambient temperatures in cattle. These mutations result in the truncation of the ...
Effect of dry matter intake restriction on energy balance, ruminal fermentation, and nutrient retention by beef steers
(University of Missouri--Columbia, 2005)
Two studies were conducted to determine the effects of DMI restriction on digestion and metabolism by feedlot steers. In Trial 1, 12 Angus X steers (BW [almost equal to] 450 [plus or minus] 18 kg) were assigned randomly ...
Uterine regulation of preimplantation embryo development in fertility-classified heifers
(University of Missouri--Columbia, 2018)
Infertility and subfertility represent pervasive problems in domestic animals and humans, and embryonic mortality is a major factor influencing reproductive efficiency. In cattle, the majority of embryonic loss occurs ...
