Seems folks like to spend money - or reccommend we spend money on cattle. I would suggest you sit down and potentially re-think your operation. There is always room to revamp if one looks objectively at how things run.
Genetics, genetics, genetics.
We have never wormed a cow in my life. We vaccinate - Modified live vaccine for Bovine Pneumonia, IBR, BVD, PI-3, BRSV.
8 Way for Black Leg, Dysentry, Hepatitus, Edema and Tetanus.
Tetanus was a surprise to me - it is buried in the Covexin 8 Way - did not know it was there.
I looked the above information up the other day for a friend.
We never creep and we never used store bought sacks of any type of feed - generally we buy mineral and salt. Otherwise it is straight hay and when I feel generous - some corn. Never feed it when the temp is above minus 20 - 30. They simply do not need it. We never spend money on straw - they sleep on the snow and they seem to do very well as long as they are out of the wind.
I figure the total cost per head for meds is less than 15 bucks per head on an annual basis - and we never have had any probs we could not handle - not to say it will not happen, but so far so good.
If you run a closed herd you can cut down dramatically and increase your profits.
Sit down and take a long hard look - you may find you are not committing heresy - you may simply be deciding to raise cattle in the way they were designed to be raised.
Bez!
