The effects of various levels of dietary protein on high producing dairy cows in early lactation

Creator:

Pangborn, Marvin Clark

Abstract:

This project was designed to test the biological effects of three levels of dietary protein (12.7, 16.3 and 19.3% CP on a dry matter basis) on high producing Holstein-Friesian dairy cows. Forty five second lactation or older cows that showed the potential to produce over 31.75 kg (70 lbs) per...

Comparative values of corn and corn cannery waste silages for milk production in dairy cattle

Creator:

Meyers, George Henry

Abstract:

The production level of dairy cows fed corn cannery waste silage was investigated during a 305 day lactation study. Eighteen Holstein cows were paired according to their probable producing ability and field corn silage was fed to the control pairmates, Forage analyses (DM, CP, CF, and nitrates) were determined on...

Performance of dairy cattle under two feeding regimes, dry lot and irrigated pasture

Creator:

Kyeyune-Sendagi, Aloysius Lloyd

Abstract:

Four experiments were conducted (1961-1964) for the primary purpose of studying the milk and milk constituent yields of dairy cows under dry lot and pasture systems of management. The secondary purpose was to compare the health and breeding performance of cows under these two systems. Ninety-eight cows of the Holstein...
