Potential diagnostic methods and nutritional changes to combat bovine respiratory disease in receiving cattle
(University of Missouri--Columbia, 2017)
Bovine respiratory disease (BRD) accounts for up to 70 percent of health disruptions and $500 million in associated medical costs and production losses, thus receiving considerable attention from cattle health personnel in production and research...
Effects of essential oils on the performance, health, and feeding behavior of growing cattle
(University of Missouri--Columbia, 2021)
Concerns and changes in policy related to use of antimicrobials in livestock has led to increased interest in using alternative feed additives such as essential oils (EO). Essential oils are plant secondary metabolites ...
Improving viability of immunodeficient RAG2-/- pigs by non-specific porcine antibody administration
(University of Missouri--Columbia, 2020)
. Their immunodeficient state shortens their lifespan to 1-2 months, but most applications of this model will require that the pigs survive beyond 2 months. Therapeutic antibodies are used clinically to treat immunodeficient, autoimmune, and inflammatory conditions. Human...
Effect of ovulatory follicle size on bovine pregnancy associated glycoproteins in beef cattle
(University of Missouri--Columbia, 2010)
following GnRH-induced ovulation of 14 to 15 mm compared to 12 to 13 mm follicles. The first increase in bPAG occurred on d 24. There was an effect of day on bPAG but no effect of ovulatory follicle size or ovulatory follicle size by day interaction from d...
Effects of bovine pregnancy-associated glycoproteins on gene transcription in bovine endometrial explants
(University of Missouri--Columbia, 2021)
obtained and flushed to determine if a conceptus was present. Endometrial explants were collected and split between 4 groups: pregnant with and without 15 [mu]g/ml PAG (n = 10) and nonpregnant with and without 15 [mu]g/ml PAG (n = 9). Endometrial explants...
Investigation of methods and factors influencing mouse oocyte quality, in vitro fertilization and embryo development
(University of Missouri--Columbia, 2018)
Mice are one of the most commonly used rodent species as a model for biomedical research to better understand molecular, genetic, and cellular causes of human disease and disorders. The production of good quality oocytes ...
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 from hatch to 21 days of age...
Effects of aflatoxin on hepatic gene expression in a poultry model
(University of Missouri--Columbia, 2008)
To determine the effects of dietary aflatoxin on hepatic gene expression in chicks, seventy five day old-male broiler chicks were assigned to three dietary treatments (0, 1 and 2 mg/kg aflatoxin/kg of feed) from hatch to day 21. At the end...
Molecular regulation of fetal brain development in pigs
(University of Missouri--Columbia, 2021)
-seq). Hotspots of methylation in specific chromosomal regions were observed in the analysis. The analysis identified 1,475 sites in the pig genome that were methylated in the fetal brain, irrespective of sex, during development. The same sites were methylated...
Regulation of early trophoblast differentiation and development
(University of Missouri--Columbia, 2010)
or the addition of 8-bromo-cyclic AMP had a modest ability to up-regulate bovine IFN-[tau]1 reporter constructs (usually no more than 4-fold), co-expression of PKA and Ets2 led to a more than 500-fold increase in gene expression . Progressive truncation...
