About the author

is an industry leader in developing bulls on forage, and is internationally known as a successful rancher and businessman. In the mid 80s, Kit started out by leasing grassland and buying cows. In the beginning, he strived to build a herd that would wean bigger calves, but quickly learned that increasing weaning weights did not increase profit. Kit then changed his management approach to be profit-driven instead of production-driven, and carried-out management practices to reduce and eliminate expenses. At the same time Kit implemented ways to increase beef production per acre – compared to beef production per calf. Over the last 25 years, Kit has grown his ranch into a very profitable family corporation. From the first production sale of 7 bulls in 1990, Pharo Cattle Company now produces and markets over 800 forage-developed bulls every year. Kit Pharo advocates several no-nonsense ways to put profitability back into ranching and publishes a quarterly newsletter that is sent out to over 20,000 people.


  1. Rob Havard says:

    Agree with most of this but two points worth considering.

    Frame 5 cows are fine if you live in an area where you can grow and conserve high quality forage. Basically just keep reducing frame size until everything breeds back and holds condition in relation to your environment. Then keep that frame size – no need to get smaller.

    Whether you finish/fatten your calves or whether you sell weaned stock you need to provide somewhere near what the feeders or processors want. My red line is the size of my finished heifers. If they do not reach 260 kg (570 lbs) deadweight by 28 months then they are no good to my feeder customers or to the processors – due to the cost per head of processing compared meat yield per carcasse. You could direct market your heifers and go smaller but that is more work.

    I basically need the smallest cows possible to produce the above. Certainly no bigger.

    Did ND frame score the cows?


  3. Paul Nehring says:

    And…the more cows you have, the more bulls you will need to buy…Sorry, Kit, I couldn’t resist.

    Another thing on the size issue is that bigger cows tend to have bigger calves, and have more trouble calving, so fewer weaned calves. This was also demonstrated in the information that Dr. Allen Williams collected.

    a. Based on Southeastern IRM data (Integrated Resources Management).
    b. Average weaning weight divided by no. of cows exposed for breeding.
    c. Based on Southeast avg sale barn value (Dec. 2003)

    Also, bigger cows have more problems breeding–maybe it’s through maintaining enough energy, as Kit mentioned, and/or maybe it’s because strength does not increase in direct proportion to the size of an animal. A cow that weighs 1800 lbs is not twice as strong as a cow that weighs 900 lbs, yet she must carry twice the extra baggage over rough terrain. That means bigger cattle will have higher cull rates due to injury.
