The Farmer’s Guide to Ruminant Nutrition is your solution to take control of your production and profit! It is a six-step system to help you organise your feeding program to meet your economic goals by tailoring decisions to your specific environment and animals. When feeding the right thing, the right way at the right time, you will achieve better production results from your animals and make more profit with less effort and expense. We will help you, step by step, to develop your own simple, organised and profitable nutrition plan.

You will be able to:

Reduce costs

Increase production

Increase profit

Understand how to respond to sales talk

Make nutritional decisions from an ‘informed’ basis

Create a nutritional plan that is specific to your property and animals

“It’s been brilliant working through the modules in the Farmer’s Guide to Nutrition at my own pace. I love being able to stop and start the recordings as I relate the information to my own situation via the spreadsheets included. I also love being able to go back and use this tool as a refresher as the seasons change throughout the year, and also from year to year. It gives me the added confidence that I’m feeding the right thing, in the right amounts, at the right time, for the right reason.”

About Dr. Terry McCosker

Terry’s mission is to change agriculture in Australia. He has a vision for a ‘regenerative’ agricultural landscape, including, people, land, livestock and businesses.

Here is just a little of his background…

Dr. Terry McCosker, director of RCS, is an internationally acclaimed teacher and has worked in research, extension and property management in both government and private sectors since 1967.

In his research era, Terry published over 40 papers and made several world first discoveries in the 1980s in the fields of bull fertility, ruminant nutrition, animal production and pasture ecology.

Terry developed his passion for ruminant nutrition in the 1980s when he was tasked with improving the production on a cattle station in northern Australia, running 12,000 breeders on 310,000ha.

During this process he:

  • Developed the concept of nutritional seasons, which he has been since used hundreds of times to both diagnose and explain the nutritional requirements of ruminants.
  • Was the first to discover the north Australian wet season protein deficiency.
  • Released the first documentation relating individual species and ecological health to animal production in the world.
  • Published numerous nutritional papers.
  • Co-authored a book on phosphorus nutrition.

He has studied pasture development and animal nutrition in the US, Colombia, South Africa and Brazil. Terry developed the concept and managed the team which produced the first useful genetically modified rumen bacterium in the world. Among other things, he introduced the concept of Low Stress Stock Handling to Australia through Bud Williams, introduced and continued developing the acclaimed GrazingforProfit™ School and pioneered the soil carbon economy.

Terry has maintained his passion for ruminant nutrition and over 15 years ago he developed a face-to-face nutrition training program for teaching ruminant nutrition to farmers and graziers around Australia.

The Farmer’s Guide to Ruminant Nutrition is a culmination of Terry’s extensive experience into a simple six-step process you can follow along at home and implement to increase profitability and confidence in your nutritional decisions.

Based on the RCS Ruminant Nutrition Workshop attended by over 700 farmers Australia-wide.

Dr. Terry McCosker has drawn on his 49 years of experience and knowledge with animal nutrition to produce a simple 6-step process that you can now learn at home:

Step 1:

Number 1The focus is all about you in this first module! You will spend time mapping out your own personal circumstances for the environment in which you live. You will match your feed curves with feed supply throughout the year and uncover the nutritional seasons on your own property. From the start, you will clearly map your own circumstances so you can apply the theory covered in the course directly to your situation and develop your own profitable feeding program.

Step 2:

number 2

Now that we’ve focused on you and the seasons on your property, it is time to turn the focus to your animals. In this module we look at rumen design, its function, the impact of what you are feeding and when you are feeding in terms of the biological processes taking place in your animals. We take a practical look at energy, water and nutrients and the application of this to your nutritional program.

Step 3:

number 3

There are two forms of protein, bypass protein and rumen degradable protein. In this module we look at rumen degradable protein in depth. We take a very hands-on approach, firstly looking at why rumen degradable protein is important and secondly looking at the practical aspects of when and how it is most appropriate to feed in order to get maximum profit and production.

Step 4:

number 4

The last step, before we pull it all together and create a nutritional program specific to your circumstances, is to cover the key concepts of bypass protein and minerals. We journey through the what, why, how and when of feeding bypass protein and look how to diagnose and appropriately supplement animals with mineral deficiencies and a specific look at free choice mineral supplementation.

Step 5:

number 5

Combine the information you have learnt in a concise, easy-to-implement nutritional plan. While developing your plan we will focus on three important areas: 1) setting goals for productivity 2) matching supplements to the nutritional seasons for your particular environment and 3) determining the profitability (gross margins) of feeding scenarios.

Step 6:

number 6

It’s always handy to learn from those who have walked the path before you. In this module we take time to share stories of other people’s successes and mistakes, giving you the opportunity to learn the dos and don’ts and to save lots of time and money in the process. This module involves detailed Frequently Asked Question sessions with Dr McCosker and will set you on the path to success.

Each step includes:

Video training modules, audio of each session for on-the-go listening, worksheets to help you apply your insights immediately and fill-in-the-blank templates for fast implementation.

When purchasing the Physical Pack, you also receive a 200 page resource manual to help you employ the strategies in each module, a USB loaded with the training videos and templates, a 6-pack audio CD set and a summary & implementation toolkit for quick review and fast action.

The Farmers Guide to Ruminant Nutrition


Dr. Terry McCosker held a Ruminant Nutrition Webinar which had over 300 producers registered. On this webinar he covered the current seasonal conditions - what they mean in terms of animal nutrition and what you can do now; the three most common mistakes he sees – how to easily avoid them; how to ensure your feeding program makes you money (and not get carried away by the sales talk); and he also spent over half an hour answering key questions from producers.
