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 ... -
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 ... -
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 ... -
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. ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ...
