Influence of subclinical hypocalcemia on plasma biochemical parameters, liver histologic changes, and common postpartum diseases in dairy cows
(University of Missouri--Columbia, 2011)
We hypothesized that cows with subclinical hypocalcemia at calving would have greater elevations in liver associated biochemical parameters and non-esterified fatty acid (NEFA) concentrations compared to normocalcemic cows. ...
Effects of dietary melamine and cyanuric acid in young broilers and turkey poults
(University of Missouri--Columbia, 2011)
Six studies were conducted to determine the individual and combined toxicity of melamine and cyanuric acid (up to 3.0%) in young broilers and turkey poults. Melamine alone caused reduced growth, increased kidney weights, ...
Establishment of a phenotypical model of adverse outcomes associated with assisted reproductive technologies
(University of Missouri--Columbia, 2011)
Beckwith-Wiedemann syndrome (BWS) is a loss-of-imprinting pediatric overgrowth syndrome. BWS is speculated to occur primarily as the result of the misregulation of imprinted genes associated with two clusters on chromosome ...
Negative biomarkers of sperm quality and male fertility
(University of Missouri--Columbia, 2011)
Semen evaluation via traditional light microscopy provides information about sperm motility and basic morphology but has a limited ability to predict reproductive performance in an assisted reproduction setting. In-depth ...
Shelf stability and quailty of fresh ground pork and pork sausage from pigs fed ethanol co-products
(University of Missouri--Columbia, 2011)
This experiment was conducted to determine the effect of swine diets on subsequent meat quality characteristics and shelf life of ground pork products. Pigs were fed one of 8 different dietary treatments using dietary ...
Response of Bos taurus cattle to fescue toxicosis and heat stress comparing by region and breed
(University of Missouri--Columbia, 2011)
Two studies were performed to determine response differences in heat-sensitive and -tolerant Bos taurus cattle to heat stress and fescue toxicosis in controlled and field environments. Romosinuano (RO), a tropically adapted ...
Comparison of long-term CIDR-based protocols to synchronize estrus in postpartum beef cows
(University of Missouri--Columbia, 2011)
Estrus synchronization and artificial insemination are two of the most important management practices available to producers to increase reproductive performance in a beef cow-calf operation. Unfortunately, a small number ...
Size-dependent acquisition of global DNA methylation in oocytes is altered by hormonal stimulation
(University of Missouri--Columbia, 2011)
Administration of exogenous gonadotropins (superovulation) is used to increase the number of mature oocytes to circumvent the inefficiencies of the subsequent assisted reproductive technologies procedures. Some evidence ...
Effect of ovulatory follicle size on steroidogenic capacity, molecular markers of oocyte competence and bovine pregnancy associated with glycoproteins in beef cows
(University of Missouri--Columbia, 2011)
Artificial insemination (AI) and estrus synchronization (ES) are effective tools for the genetic advancement of cattle. Gonadotropin-releasing hormone (GnRH) is used at the beginning of ES protocols to induce ovulation and ...
Phenotypic and genetic effects of disposition on beef tenderness and quality attributes
(University of Missouri--Columbia, 2011)
Cattle temperament (exit velocity; EV) and steak tenderness (Warner-Bratzler shear force) have been shown to be associated in Bos indicus cattle (Behrends et al., 2009). Both traits potentially provide opportunities for ...
