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!

Calf and Heifer Nutrition and Feeding of Dry Cows

Calf health, growth, and productivity rely heavily on nutrition and management practices. Every heifer calf born on a dairy farm represents an opportunity to maintain or increase herd size, to improve the herd genetically, or to improve economic returns to the farm. The objectives of raising the newborn calf to weaning age are optimizing growth and minimizing health problems. In this video we will discuss the development of the calf's digestive system, learn how important colostrum is for the immune system, and the nutrients the calf needs to be healthy and grow well. We will discuss critical phases of growth for the dairy heifer, the importance of good facilities, and how nutrition plays an important role in getting a healthy well grown heifer ready to be bred and prepared to have her first calf.Proper management and nutrition of the dairy cow transitioning into lactation is very important for obtaining a healthy calf, increased reproductive efficiency and optimal milk production in the following lactation. We will learn how this can be achieved by feeding balanced diets, providing good cow comfort, and assuring the cow is in good body condition before and after she calves. There are many feeding strategies that work for feeding dry cows however the goal should always be to provide high quality feed sources, consistent availability of feed, adequate bunk space and a comfortable environment. We will discuss  how best to manage and feed the dry cow prior to calving so she can transition into lactation with a healthy calf and produce high quality milk. 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!

Dairy Reproduction

This week you will learn basic concepts related to reproduction on dairy farms. We will start with a discussion of the life cycle of the dairy cow and how to adequately prepare a heifer for her fist calving. Next will be a discussion of the basic anatomy and function of the male and female reproductive tracts. This will be followed by an overview of the bovine estrous cycle and the main hormones and ovarian structures that control the cycle. We will follow this with a discussion of factors controlling the expression of estrus by dairy cows and how to be more effective at detecting estrus. We will highlight the critical need to time ovulation and insemination to maximize conception rates and will discuss some of the factors which reduce conception rates. This will be illustrated by a discussion of the key reproductive metric, pregnancy rate. Viewers will learn about strategies to increase pregnancy rates and will better understand methods used for pregnancy detection along with the critical need for early and accurate pregnancy detection to maximize the farms’ pregnancy rates. 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.

Animal Health and Milk Quality

In Week 7 of this course, you will learn about disease concerns of dairy cows and calves and management practices addressing diagnosis and prevention. Our discussions will progress from first establishing disease prevention concepts of biosecurity and evolutionary change to dairy herd health programs. The next three discussions will focus on disease issues related to the calving cow, calf and lactating cow. These lessons will provide background information and practical skills in recognizing disease problems early in an effort to minimize adverse consequences on animal health and performance. The last two discussions will focus on disease treatment and prevention practices in addressing important conceptual approaches as specific mechanisms for treatment and prevention are dependent upon regulatory issues within a given country. We will address the controversial issue of antibiotic usage in the treatment of cows as an important concern for food production, but also as part of good animal care and ensuring animal welfare. Preventive practices of vaccination strategies and parasite control will be framed in a conceptual approach that could be applied to differing farm situations. Finally our discussion will emphasize the importance of good nutrition, thus linking information from other course modules, to establishing proper dairy management practices to ensuring quality cow care and minimizing disease risks. 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.

Farm Economics and Environment

In Week 8 of the course, you will learn about the basics of dairy farm management and identify some key aspects of farm level economics that impact farm productivity and profitability. From crops to cows to cash, the dairy farm is an economic engine that has positive impacts on local communities. The second part of this series expands on dairy’s local impact to provide a global view of dairy markets around the world. From price volatility to seasonal milk supplies, the world marketplace for dairy products is complex. In the last lectures of this course we will discuss the environmental implications of dairy production and strategies for decreasing nitrogen, phosphorus, and greenhouse gas emissions from dairy operations. 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!
