You can raise better cattle in a small herd than are available in large herds. There are reasons. They can cull 50% and still have a lot of sale cattle which means that 50% of their cattle are faulty.
Your money is real and limited so you will only gamble on high odds cattle. You do not have to advertise as wildly and as widely. You will either make or break your own sales if you put too little or too much money into your program. You need to be about average of your neighbors in feed but above average in forage and management.
1-Your cows need to fit your environment and be trouble free. These cows will produce cattle that will fit in your neighbors' herd and do good for them. You will sell no farther from home than, generally, 50 miles or maybe out to 100 miles.
2-Your cows are your base. Mess them up and you go down the drain. Build them right and raising cattle will be a great pleasure.
3-Terminal sires are a dime a dozen. Breed for great cows (maternal) and raise bulls that will make great mama cows in your area. They are scarce if they have no holes. You will be able to sell all with word of mouth some years. Don't just show buyers the bulls; show them the cows.
4-Buying: forget bloodlines, herd prefixes, show heifers and high EPDs. Checking calving regularity, breeder honesty and pride/ego level, proper type, hair quality and convenience traits: docile, good udder and teats, correct stride, proper size for your environment and ball park FS for your neighbors to buy and have calves that sell well in the local barns.
5-Never plan to or try to compete with the big boys. Some of that is smoke and mirrors and the rest of it is mirrors and smoke.
6-Never bet money or pay much for an unproven outcross bull. You can build proof with other's testimony and experiences whom you can trust. Always breed the type you want and type to type. Fire and ice matings produce a puddle of water.
7-Do not fear linebreeding of great fitting cattle. Most mainstream breeders linecross purebred animals continually to fix the faults of the last great bull they used in their herds and they always will.
8-Only sell what you are willing to use. You cannot use them all because of shear numbers, logistics and inbreeding but it is a way to judge keep/cull.
