Tell me about the lawn mower.

There are many cows and weeds all year round. Cattle need to eat roughage and concentrate. Concentrated feed can be purchased and processed by itself, saving some money, but it can't be obtained for free. It must cost money, and coarse grains can be obtained for free. Generally speaking, the grass you grow is basically free, because the cost is very low, and you can get dozens of tons of output by investing a few hundred yuan.

First of all, cutting weeds outside is not available all year round. Grass can be found in spring, summer and autumn. However, the difficulties will become more and more serious. After entering autumn, the number of outdoor weeds will be very small. If winter is desolate, it is basically impossible to mow the grass and feed the cattle. Secondly, it takes time and effort to plant grass and raise cattle. An adult beef cattle needs 30 kilograms of hay every day. If it is fresh grass, the number will double.

In other words, a cow needs to cut 60 kilograms of grass. If 10 cattle need 600 kilograms, this figure is not arbitrary. It will take a long time. Losing 600 kilograms a day may not be enough, and it is indeed faster than direct storage. Last but not least, most mowing is done by mowing outside. These grasses are not as delicious as yellow bamboo grass. Grow slowly, not suitable for raising cattle.

It can be said that mowing grass to raise cattle is not reliable, but saving feed will delay growth. In some rural areas, you can see mowing grass to feed cows, but generally only one or two cows are raised, and the amount of mowing grass is not large. In addition, some cattle farmers can't raise cattle when it rains, so they choose to mow grass to raise cattle. There really isn't. They are all mowing grass and raising cattle. This is not feasible. It is best to plant grass and raise cattle directly to ensure feed supply.
