Milko-Tester Analysis Of Milkfat Content Of Churned And Nonchurned Samples From Jersey And Holstein Dairy Cattle, Kazuko Monobe
Milko-Tester Analysis Of Milkfat Content Of Churned And Nonchurned Samples From Jersey And Holstein Dairy Cattle, Kazuko Monobe
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Milk samples from three Jersey and three Holstein herds were used to determine if the degree of churning correlated with the initial milkfat assay, and also to determine if the churned milkfat could be measured as accurately as the initial milkfat using the Milko-Tester.
Regression lines for the initial milkfat test versus churned milk- fat test fit polynomial curves. The degree of churning was greater for Jerseys than Holsteins and correlated with the initial milkfat test.
The repeatability of initial milkfat tests vas 0.98 for Jerseys and 0.99 for Holsteins. However, the repeatability of churned milkfat tests was lower for …
