I am a sheep farmer, and I have both stocking experience and captive experience. Next, I'll help you figure out how much profit you can make a year by investing100000 yuan purely by experience to raise 40 ewes.

First of all, it needs to be explained here: it is impossible to make a profit by relying solely on ewes. Forty ewes must have two excellent breeding sheep to breed offspring, so that they can live endlessly from generation to generation and get more benefits.

In fact, there are many kinds of pure grazing, and most of them can be pure grazing. Among sheep breeds, only singleton sheep is suitable for pure grazing, and many sheep breeds such as small-tailed Han sheep and Hu sheep are not suitable for pure grazing.

In order to get better economic benefits, we'd better simply raise more sheep, but at the same time, we must ensure that it can adapt to the local climate conditions. Take many black goats as an example.

Take Jintang Black Goat as an example, you can have two babies a year or three babies every two years, with 2 ~ 4 lambs each, and the survival rate of lambs can probably reach above 80%. Assuming that 30 ewes out of 40 ewes can give birth to lambs, and/kloc-0 can give birth to 2.5 lambs on average, then 75 lambs can be given birth. According to the lowest survival rate of 80%, the number of lambs in the whole year is about 60. We know that raising sheep is basically not fattening. The price of sheep is high this year, especially the price of lamb. 1 3-month-old weaned lamb can be sold for more than 800 yuan, and the profit of lamb alone can reach about 50 thousand yuan. The cost of pure sheep raising is low, and there is little supplementary feeding, so this 50 thousand yuan is almost pure profit. That is to say, if you invest100000 yuan to raise 40 Jintang black goats and two excellent breeding sheep, you can make a net profit of about 50000 yuan a year.

Finally, conclusion: The above is only taking Jintang Black Goat as an example. If the prolific goats are purely stocked, this profit is basically the same, and it should not be much different. But if the pure grazing is a lamb, this profit will be reduced by almost half.
