Production

Managing Dairy Grazing for Better Grass and More Milk - Pasture and grazing management is a science that dairy managers can learn and apply. The study of how pastures grow and how the dairy cow uses them provides the scientific knowledge needed to manage pastures effectively.

Owning a Dairy Cow or Goat - If you already own a cow or goat, this publication will give you information about caring for your animal and using the milk produced. If you are still choosing, remember there is a tremendous variation in the capacity of individual dairy cows and goats to produce milk.

Raising Newborn Calves - There are several reasons for raising calves without their mothers. Occasionally, a cow dies giving birth or doesn’t produce enough milk to support a growing calf. Some people buy calves to raise for beef and use grass grown on a few acres.

Good Farm Equipment Sanitation Means Better Milk Quality Tests - For any dairy food, milk bacteria counts, handling, and cleanliness dictate the flavor and keeping quality of the finished product. High-quality milk with low bacteria counts and the potential for long shelf life starts on the farm with clean, sanitized cows and equipment.

Grass-Based and Seasonal Dairying - Grass-based dairies differ from confinement dairies because cows harvest their own feed, reducing the need for costly supplemental feed and other purchased supplies. However, they require considerably more management skill. Seasonal operations have increased challenges in breeding all cows in a short period and in planning for loss of income during the off season.

The Economics of Grass-based Dairying - Discusses economics of dairies, land requirements for grazing dairies, supplemental feed, seasonal dairies, labor and profitability.

Raising Dairy Heifers on Pasture - Offers references on pasture and grazing, discusses custom heifer-raising and costs of raising heifers on pasture.

Manure & Nutrient Management

Nutrient Management for Dairy Production: Dairy Manure as a Fertilizer Source - This publication examines several aspects of the nutrient content and value of dairy manure: Nutrient flow through a dairy, distribution of nutrients in manure, dairy manure nutrient content, and the value of manure.

Reducing the Risk of Groundwater Contamination from Livestock Manure Management - The challenge in managing manure is to apply it in the quantity and method that will meet the following objectives: provide the proper amount of nitrogen and phosphorus, prevent manure from being carried off the land surface due to runoff, and assure that nutrients are not carried beyond the root zone to contribute to ground-water contamination.

Manure Management in Small Farm Livestock Operations: Protecting Surface and Groundwater - Clean, safe water for consumption, recreation, irrigation,  manufacturing, and fish and wildlife habitat is important to Oregonians. Nonpoint source pollution is the major cause of water quality degradation in Oregon.

Composting: An Alternative for Livestock Manure Management and Disposal of Dead Animals - Livestock producers constantly face the challenge of managing manure, dead animal disposal, and meeting environmental regulations. Composting is a possible alternative for handling manure. The benefits include reduced volume, enhanced soil fertility and texture, and reduced environmental risk.

Nutrition

Dry Cow Feeding Management - 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. Proper care and feeding at this time will return more milk and healthier cows in the next lactation.

Evaluating Grain for Livestock Feed - Producers need to develop "a good eye" for grain quality. The purpose here are to define those grain characteristics that you can visually evaluate and to discuss their importance in determining the feed value of a grain.

Meeting the Nutritional Needs of Ruminants on Pasture - Provides managers with tools and references to consider biological and climatological variables and make decisions that ensure the ecological and economic viability of a grass-based ruminant livestock operation.

Feeding the Dairy Cow During Lactation - Information on the main stages in the lactation cycle of dairy cows, lactation biology, and feeding.

Health

White Muscle and Other Selenium-Responsive Diseases of Livestock - The underlying cause of white muscle disease is a dietary deficiency of the trace element selenium (Se). There is a fairly clear-cut relationship between soil, plant, and animal factors.

Other Dairy Resources

OSU Extension Dairy Program - The Dairy Processing Program at Oregon State University is primarily an extension program. The mission of this program is to promote the production of safe and high quality dairy products and to support a healthy and sustainable dairy industry in Oregon.

Oregon Department of Agriculture Rules and Regulations for Dairies - License requirements, milk safety references, and resources.
