Mr. Judy particularly focuses the operation/work of Ian Mitchell-Innes who is a South African rancher he works 14,000 acres and uses Holistic Planned Grazing to manage his farms. He grazes 4,000 to 6,000 head of cattle per day on a 100 acre paddock! Did you catch that ... 4,000 to 6,000 head and 100 acre paddocks ... that blew me away and think this is the point where I would have said, "This can't work for me," if I hadn't continued reading on. Mr. Mitchell-Innes has seen his ranch improve endlessly through his management system that focuses on using the livestock to improve everything. Oh, and Mr. Judy also is quick to point out that all the improvements that Mr. Mitchell-Innes has made on his land has come without the use of lime and fertilizer. You just have to read the chapter to get the rest, but if you can't tell ... I think it's great!
In chapter 23 Mr. Judy answers the question of how this high density grazing thing can work with numbers fewer than say ... 4,000. He has been doing mob grazing (another phrase you will see a lot) with 50 to 250 head of cattle and believes that it will work on numbers smaller than that, and I tend to agree. When he was writing this book he was mobbing up his cattle herds in densities between 100,000 and 500,000 pounds liveweight per acre and he writes the results were "dramatic". The main issue and difference between this mob grazing and Management Intensive Grazing that he used to be doing was that in the MiG system they were focusing on keeping the grass young and grazed before it went to seed. With the mob grazing they allow the grass to get older and by doing so let the root system fully rejuvenate so that as the season progress the grass can handle the weather changes better.
I could go on and on! But, I would just suggest at this point you pick up the book and read for yourself. I for one can't wait to get my cattle mobbed up once the grass starts to take hold and get growing. The benefits seem endless ...
