To reduce the loss of feeding calves during the nursing period
and to conserve milk for human consumption research has been conducted
to develop milk replacer formulas which result in calf performance
comparable to that of milk. In the first section of this investigation
different aspects of utilization of fats,...
A four months continuous feeding trial was conducted
to evaluate Canola meal as a single protein supplement in
complete dairy rations. Thirty high producing Holstein
cows in the second week of lactation were randomly alloted
in groups of ten to one of three isonitrogenous (15% CP)
and isocaloric (1.6 Mcal/kg...
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...
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...
Evaluations of body form and measures of milk production were
recorded for 188 Holstein lactations and 77 Jersey lactations in the
Oregon State University Dairy Herds. Components of body form
included general appearance, dairy character, body capacity, and
mammary system and 34 sub-components of these four traits plus body
weight...
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...
