  • Biological characteristics of Katahdin sheep selected for footrot resistance 

    Azarpajouh, Samaneh, 1984- (University of Missouri--Columbia, 2014)
    The objectives of this study were to select sheep divergent for a footrot resistant genotype by screening with the DQA2 gene marker and to investigate the host resistant immune response, neutrophil phagocytic efficiency, ...

  • Comparison of rumen microbe taxa among wild and domestic ruminants 

    Taxis, Tasia Marie (University of Missouri--Columbia, 2015)
    Microbes that inhabit the rumen provide a diverse set of enzymes that degrade ingested plant material. Without microbes, ruminants could not survive. Our research has focused on identifying microbial taxa associated with ...

  • Genetics in practice : applications of quantitative genetics to environment and educational pursuits 

    Haag, Maria Therese (University of Missouri--Columbia, 2018)
    "The ability to elucidate quantitative trait architecture and introduce potentially beneficial traits makes introgression a useful tool. Unfortunately, due to the nature of inheritance there are certainly limitations to ...

  • Genotype by environment interaction estimated by using reaction norms in cattle 

    Maricle, Elizabeth Ann (University of Missouri--Columbia, 2008)
    The objective of this study was to evaluate GxE by comparing reaction norms among U.S. Angus bulls. Dependent variables were adjusted weights at birth, 205 d weaning, and 365 d yearling. Environments were defined as progeny ...

  • Genotype by environment interactions for growth and stayability in US red Angus 

    Fennewald, Dennis (University of Missouri--Columbia, 2012)
    Genotype by environment interactions (GxE) may reduce accuracy of sire selection. The objectives of this study were to evaluate the presence of GxE by comparing reaction norms of bulls for birth weight, weaning weight, ...

  • Mitigation of effects from heat stress by Artemisia species 

    Selby, Catherine Clare (University of Missouri--Columbia, 2012)
    [ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Artemisia afra (AF) is a herb used by indigenous peoples of South Africa to alleviate heat stress during desert travel, and Artemisia absinthium (AB) ...

  • Selection for parasite resistance in Kiko x Boer goats 

    Thomas, Chevise Latoya (University of Missouri--Columbia, 2015)
    In the United States, goat production has increased over the last three decades because of their economic value as efficient converters of low-quality forages in quality meat, milk, and hides for specialty markets. However, ...

  • Selection for placental efficiency in swine 

    Mesa Echeverri, Henry, 1972- (University of Missouri--Columbia, 2004)
    With the overall goal of increasing profitability by increasing litter size, two lines of pigs were divergently selected for four generations on an index of reproductive traits (n = 193 litters). The selection index (SI) ...

  • A survey of relationships among rare breeds of swine 

    Roberts, Kizzi Suzanne (University of Missouri--Columbia, 2014)
    Swine production has evolved over the last century resulting in the loss of biodiversity among breeds utilized by commercial producers. Only a handful of breeds are used extensively by these producers, with many swine ...
