If you keep a journal, you may find that farm management software can help you keep track of details about your herd that you may have kept in your head or should have written about in the past. You can download the latest farm reporting software via https://fwagronomy.com.au/products/#farmqa to track all the data.
These are some of the things you will write for the herd, but you will also want to keep track of when cows are inseminated, when they breed and how much milk they produce on average. These things can help you raise the best animals and get rid of animals that are not worth the cost of their feed. Diseases can be noted just like any other health problem.
Farm management software isn't just for livestock. Anyone who owns pigs, chickens, horses and other animals can use the software to keep tabs on everything that's going on.
If you have a dispute with a vendor, wouldn't it be better to click your mouse a few times to see the total amount you paid, or should you be paid if the number they provide doesn't match yours? How about a calendar that automatically alerts you when there's an auction or when you need to mow the lawn? These are all good memories.
There are several brands of farm management software packages that you can usually buy, or you can buy accounting software and other ways to do what you need. It depends on what you want to use and what you need to do with your software.
