With the world's first MOOOOO-C, you will gain a broad and comprehensive understanding of all aspects of dairy management such as genetics, nutrition, reproduction, animal health, farm economics, and sustainability of dairy production systems. There's something here for everyone whether you are just looking for the basics or have years of experience in the dairy industry. This is an eight-week course. Each week consists of four to nine video lectures, additional reading materials, and a multiple-choice questions quiz. Estimated study time is between three and five hours per week. Learners have the option to purchase a Course Certificate for 49.00 USD. The certificate can be purchased at any time, but you must verify your identify before taking the course quizzes in order to be eligible. For those who cannot afford the certificate fee, financial aid is available through Coursera. Why is producing milk efficiently and sustainably so important? Milk provides humans with over 16 essential nutrients, such as: Energy, Protein and Essential Amino acids, Vitamin A, Vitamin D, several B vitamins, including B12, Pantothenic and Folic acids, and essential minerals such as Calcium, Magnesium, Phosphorus, Potassium, Zinc, as well as other minerals. Did you know that one glass of milk provides a 5-year old child with 21% of his/her daily protein requirements and 8% of their energy needs? Most milk in the world, about 85%, is produced from cattle. However, water buffaloes, goats, sheep, and camel are also dairy animals. The United States, India, the European Union, Brazil, and New Zealand are among the largest dairy producers in the world. Yet among these dairy-producing countries there are varied methods to generate milk with highly variable productivity and efficiency. Dairy production is vital for the survival of billions of people. Globally, around 150 million small-scale dairy households, equivalent to 750 million people, are engaged in milk production. The number and size of dairy farms varies among countries, but in India alone, there are estimated 78 million dairy farms! In the United States, one of the leading milk-producing countries in the world, total milk production has been steadily increasing in the last decades, reaching over 205 billion pounds (93 billion kilograms) in 2014. This was accompanied by a steady increase in average milk yield per cow, reaching 22,260 lb (over 10,100 kg) per lactation in 2014. How has this efficiency been achieved? What methods are necessary to ensure production of high quality milk? How do we balance milk production efficiency with animal health and environmental protection? This course will provide the student with information to better understand dairy production systems and their role in feeding the world population. In this MOOOOO-C, you will learn about the dairy enterprise from internationally recognized dairy science professors who have delivered highly regarded dairy education programs within the United States and internationally. Course lectures are translated into Portuguese and Chinese; PDF files of these translations can be found under each course week. The Dairy MOOC team thanks Dr. Antonio Branco (Universidade Estadual de Maringá, Brazil) and Ms. Yuanyuan Zhang (Pennsylvania State University) for translating the lecture materials.

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.
