The dry, or nonmilking, period late in pregnancy is critical to preparing a dairy cow for the next lactation. Dry cows have special nutritional and management needs.
As the world population continues to grow we must look for smarter and more sustainable ways to feed everyone. Milk is the first food humans consume and is a good source of protein, fat, and carbohydrates. The following studies sought to determine the effect of feeding blackberry pomace as a...
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...
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...
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 dairy cow project may be a new project for you or a continuation of a calf and yearling project. This advanced dairy project will be interesting and provide many challenging experiences.
The dairy cow project is Unit III of the four-unit dairy project. Unit I The Calf is suggested...
As you progress in this more advanced area of your dairy project, you should find many interesting and challenging experiences.
How you develop this phase of your project depends somewhat on your home situation. If you live on a dairy farm and have a commercial market for milk, you will...
