GENETIC AND PHYSIOLOGICAL APPROACHES TO IMPROVING PERFORMANCE OF BEEF CATTLE GRAZING PASTURES IN WHICH ENDOPHYTE-INFECTED FORAGES DOMINATE
Project Number: 6227-32630-001-00
Start Date: Oct 01, 2007
End Date: Sep 30, 2011
The long-term objective of this project is to develop an improved understanding of livestock physiology and genetics to enhance the productivity and profitability of meat production from cattle grazing improved temperate pastures while reducing animal stress.
Genetic markers of cattle tolerant to heat stress will be assessed. Microarray hybridization will be utilized to obtain estimates of gene expression changes due to heat stress within breeds of cattle. In vivo and in vitro studies will be conducted to determine production practices affecting fecal shedding of E. coli and Salmonella.
