The effects of various planes of nutrition upon the cost of maintenance, reproduction, and development of beef cows
(University of Missouri--Columbia, 1916)
returns from a herd of grade cows. It was with the view of studying the effects of nutrition upon reproduction that this work was undertaken....
Interaction of metsulfuron and nitrogen fertilizer in Tall Fescue forage systems
(University of Missouri--Columbia, 2022)
Tall Fescue (Schedonorus arundinaceus) is an introduced cool-season bunch grass that is a vital component of forage systems that support beef cattle production in Missouri and much of the eastern United States. This cool-season grass is known...
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...
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 ...
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 ...
Effects of continous administration of low-dose of Escherichia coli lipopolysaccharide in chicks and poults fed non toxic doses of aflatoxin B1 and T-2 toxin
(University of Missouri--Columbia, 2005)
Six studies (three with broilers and three with turkeys) were conducted to determine if E. coli lipopolysaccharide (LPS) would enhance the effects of aflatoxin B1 (AFB1) and the T-2 toxin (T-2) in chicks and poults fed ...
