SUPPLEMENTAL CHOLINE AND METHIONINE FOR DAIRY CATTLE: EFFECTS ON PERFORMANCE, LIVER FAT CONTENT AND GENE EXPRESSION, AND PLASMA AMINO ACID AND CHOLINE METABOLITE CONCENTRATIONS
The objectives of this dissertation were to 1) determine markers of post-ruminal choline supply so that bioavailability of rumen-protected choline (RPC) sources can be calculated in lactating cows and 2) investigate the ...
Effect of grazing muzzles on grazing miniature horse behavior and physiological stress
Grazing muzzles are highly effective at reducing forage intake in horses and are a popular tool to control horse weight. However, grazing muzzle design may cause horses stress. The objective of these studies was to determine ...
COMMUNITY STRUCTURES OF GUT MICROBIOME UNDER DIFFERENT DIETS IN ANGUS BEEF CATTLE
The microbiota of animals’ digestive tract plays important roles in health, nutrient utilization, and performance. For ruminants, the digestive tract, including rumen and other gastro-intestinal regions, hosts a unique and ...
Identification of the molecular networks governing ovulation frequency in low and high egg producing turkey hens
Selection for carcass traits has negatively impacted and varied the reproductive efficiency of the commercial turkey hen, creating overall lowered egg production as well as distinct groups of low egg producing hens (LEPH) ...
ESTIMATION OF DRY MATTER INTAKE AND IDENTIFICATION OF DIETARY AND PRODUCTION PARAMETERS THAT INFLUENCE FEED EFFICIENCY OF INDIVIDUAL DAIRY COWS
The objectives of this dissertation were to: 1) develop and validate equations used to estimate individual cow dry matter intake (DMI; kg/d) based on a nitrogen (N) balance approach, 2) determine the discriminatory power ...
ANTIBIOTIC ALTERNATIVES FOR TREATMENT OF MASTITIS IN DAIRY CATTLE
Mastitis is one of the most costly diseases to the dairy cow industry. Implementation of management protocols have decreased the incidence rate of contagious mastitis pathogens, while the incidence of cases caused by ...
