Orientation and Dairy Genetics

In the Dairy Genetics module, you will learn about the different breeds of dairy cattle, their popularity and how performance varies from one breed to the next. We will consider the many different traits that are evaluated by farmers and breeders during genetic selection, and how we collect data to conduct genetic evaluations. In order to simplify the selection process we will consider selection indexes. You will learn how dairy cattle have changed over the last half-century, and the factors that alter the rate of genetic progress. Finally, you will learn about the technologies that have helped to accelerate genetic gain in dairy cattle such as artificial insemination and genomic testing. Those of you, who would like to get more engaged in discussions and are interested in completing the Course Certificate requirements, can participate in discussion forums and take the weekly quiz. We hope you enjoy learning about the genetics of the dairy cow! ...

Forage Production and Pasture Management

This week you will learn about what forages are, why they are important and the multiple roles they play on the dairy farm. We will also review some of the basic management considerations that are involved in the establishment, production and harvesting of these crops. The first lecture will focus on the multiple roles that forages play on the farm on considerations that are necessary to develop an effective forage production system. In the second lecture we will discuss some common perennial forage crops and their management. This will include alfalfa, alfalfa grass mixtures and grasses. In the third lecture, we will discuss the annual forages commonly used on dairy farms: corn, sorghums and small grains. You will learn how to utilize pastures in dairy production systems. The fourth lecture will discuss grazing and pasture management, including challenges of grazing systems, how grazing management has evolved, and proper grazing management for optimum forage and animal productivity. The fifth lecture will focus on nutrition for grazing herds, including nutrient content of pasture relative to the nutrient requirements of lactating dairy cows and strategic supplementation strategies for optimal animal health and milk production. Those of you, who would like to get more engaged in discussions and are interested in completing the Course Certificate requirements, can participate in discussion forums and take the weekly quiz. Enjoy this week's material and the entire course!...

Feeds, Hay and Silage Making, and Feed Processing

This week you will learn about feeds commonly fed to dairy cows and feed processing. We will first discuss the feeding characteristics of forages such as corn silage, alfalfa haylage, grass and small grain silages, will then move to concentrate feeds that provide energy or protein in a dairy ration, and at the end will discuss feed additives. You will also learn about the most important factors in making high quality hay and silage for dairy cows. The final lecture of this week will introduce you to processing methods designed to increase the nutritive value of forages, the importance of particle size and effective fiber in dairy rations, and most common processing methods for cereal grains and oilseeds. At the end, we will discuss how to read and understand forage analysis reports. Those of you, who would like to get more engaged in discussions and are interested in completing the Course Certificate requirements, can participate in discussion forums and take the weekly quiz.
