Effects Of Rumen-Protected Amino Acids On Production In Holstein Cows, David Paul Dawson
Effects Of Rumen-Protected Amino Acids On Production In Holstein Cows, David Paul Dawson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Six nonlactating Holstein cows fitted with rumen and duodenal cannula were used to determine the efficacy of pH sensitive fatty acid polymer encapsulation as a means protecting amino acids from rumen fermentation and as a post-ruminal amino acid delivery system. The cows were arranged in a 2 X 2 factorial in a Latin Square design. Treatments were 1) the basal ration, and 2) basal ration plus rumen-protected lysine, methionine, and threonine at 10 g each per day.
Rumen parameters measured were pH, ammonia, volatile fatty acids, protozoa, liquid, and dry matter rate of passage, total viable bacteria, and viable cellulolytic …
