"Yes." Lian Manman nodded affirmatively.
In terms of cost, the cost of raising a lamb is almost the same as that of a piglet. Although the weight of a grown sheep is far less than that of a pig, the price of mutton is higher, and the sheep's leather is also valuable. Adding these together, the profit from raising a sheep is certainly not less than raising a pig.
Raising pigs requires some grains, but sheep only need to eat grass.
If farmstead families can make money raising pigs, then running a ranch to raise sheep will surely be profitable.
As for cattle, the cost of raising cattle is much higher than that of sheep and pigs, but the value of a cow is incomparable to pigs and sheep. Furthermore, in Lian Manman's plan, her ranch would not only produce beef and mutton but also by-products like cow's milk and goat's milk.
