Miller and Hutjens, is to give students a broad overview of dairy production principles and practices in Illinois, the United States and the world. All major disciplines (nutrition, reproduction, genetics, milk secretion, health, heifer growth, milk marketing, housing, waste handling, biotechnology and international agriculture) are discussed.

ANSC 405: Advanced Dairy Management and Diagnostics

Includes sections on calves and heifers; genetics and mating; business records and management; facilities; nutrient management; forage production; pasture systems; and health; including hoof health, vaccinations, biosecurity and other diseases. 

ANSC 423: Advanced Dairy Nutrition

Advanced Dairy Nutrition includes information and guidelines from the 2001 Dairy NRC; a new section on metabolic disorders; an updated section on transition cow management and feeding, including material from the University of Wisconsin staff; and forage-based feeding approaches, including pasture as well as feeding systems, phase feeding, protein, energy, minerals and additives, and dry cow strategies. 

ANSC 435: Milk Secretion, Mastitis and Quality

An advanced course covering the physiologic basis of mammary growth, milk secretion and udder health. Topics covered include mammary gland anatomy, hormonal control, causes and control of mastitis, milk harvesting and milk quality. The course will be delivered via web-based synchronous discussion as well as online training modules. Students should have a basic course in dairy/animal science or physiology, or consent of the instructor before taking this course.

ANSC 437: Advanced Reproductive Management

Dr. Dick Wallace will lead eleven sessions along with Dr. Mike Hutjens. Topics will include female and male physiology, hormonal relationships, heat detection, new target breeding programs, health management and applications, role of feeding on reproductive function and new technologies (such as cloning, genetic engineering, and other new applications).

Dairy Ration Formulation and Balancing

The new online Ration Formulation/Balancing dairy class that features Spartan III (Michigan State University) rumen modeling software. Dr. Mike Hutjens will instruct on how to build, evaluate, and balance rations during the five sessions. Topics will include:

  • Dry matter intake guidelines
  • Energy applications (fiber, fermentable carbohydrates, and fats/oils
  • Building protein levels
  • Micro nutrients and additives
  • Case study solutions. Teams of students will work on case studies

Dairy Preventive Health Management

Topics will include biosecurity, immunology, vaccinology and protocol development, lameness and hoof care,  protocol development, records analysis, beef quality assurance, and proper drug use and residue avoidance.

Forage Production and Utilization

New one credit class, led by Dr. Mike Hutjens, for fall of 2015. The six week class will cover production, storage, and feeding aspects of the following forages:  legumes, grasses, corn and sorghum silage, small grain and sorghum/sudan grass hybrids, and pasture systems.   Additional areas will include strategic use of straw and corn stalks, reading forage test results, forage inoculants, weed control, and processing corn silage as shredlage.

Calf and Heifer Nutrition and Management

A fast pace one credit class with six weeks of instruction.   Topics are:
  • Introduction
  • Calf nutrition including accelerated growth and automated liquid feeders
  • Calf health and management including vaccination strategies
  • Heifer feeding including limit feeding approaches
  • Heifer management including breeding plans and sex semen
  • Housing heifers 
  • Heifer economic considerations  
Live classes will be held every Monday afternoon on the internet from 3 to 4 pm CDT with all live lectures archived for later review.
