I have met several people who are having a difficult time figuring out their food supply in Nevada. Specifically, their meat supply. Since many rural preppers meat supply includes livestock grazing on their farm. it makes sense that people in Nevada would want to utilize their land for the same purpose. Unfortunately, in the desert, it is acres per cow rather than cows per acre. This means the herd of cattle could be vulnerable to straying out of sight of the farmer, and straying into the sights of wildlife. In the event of some disastrous event, the cattle will also be a tasty meal or two for some unwelcome intruders.
Essentially, there are two solutions to this problem. The first is build fences and structures that are easily dependable and keep your cattle close to home. This will instantly drive your livestock production costs up in that you will need to feed them hay all year long. Since hay is very expensive, one might conclude that beef and milk might have to be off their list of food, they may keep one or two milk cows instead of beef cattle.
The second solution is agricultural and dietary in nature. Considering that 50% of all consumed protein comes from grains, perhaps stocking the important grains in your store house is the first step to assuring you have enough proteins for your family both in the first months after an event, and in the long term using the grain as seed. The other part of providing protein comes from meats. Choosing sources that are quickly raised and easily slaughtered are also sources for which their feed and supplies can be easily stocked the same as pet food. My choices are rabbit, chicken, squirrel, pigs and various other poultry species. All of these species can be raised in a barn and reproduce quickly with multiple babies in the litter or hatching.
