When is the best time to sell a pig?

Those engaged in commercial raising and @#@136@#@ of pigs naturally hope to obtain the greatest possible profit. Therefore, whether @#@227@#@ is profitable and how to obtain the greatest profit are questions that raisers must consider first. If factors such as the level of feeding technology and the type of pig are ignored, and changes in market demand are not considered, then a major factor affecting the size of the profit is how to choose the timing of selling the pig, that is, when to sell for the greatest profit. Some people may think that the bigger the pig is raised, the greater the profit after selling. Actually this is not the case. Astute raisers all know that as the pig grows, the feed cost consumed per unit of time will also increase more and more, but at the same time the rate of increase in its body weight continuously declines, and the selling price will not increase with the increase in body weight, so raising for too long is not worthwhile. Try making appropriate assumptions and establish a mathematical model for the best time to sell a pig.
