        In sows feed, * should be supplemented with sodium, chlorine, calcium, phosphorus and other mineral elements.
        1. Salt
        The content of chlorine and sodium in most plant feed is very low, so generally, salt is added to pig feed. The long-term lack of sodium and chlorine in feed will affect the appetite of pigs, the growth and production of pigs and the utilization efficiency of feed. The lack of salt of pigs, often manifested as licking pigsty, railings, gnawing soil or ashes. Foreign matter. If the salt content in the feed is too much and the water supply is not enough, it will cause salt poisoning in pigs, mainly manifested as thirst, tension, diarrhea, weakness and weight, which can cause coma and death. If pigs are found to eat too much salt, they should be given enough water and replaced with new food immediately. At present, there are more salt in the feed for pigs in China, such as fish meal, meat meal, swill and soy sauce residue. Therefore, it is necessary to reduce the amount of salt in pig diet when feeding pigs with the above feed. In sows compound feed, the amount of salt added is generally less than 0.5%, which can meet the needs of pigs for sodium and chlorine.

        Calcium and phosphorus
        Calcium and phosphorus are the main components of pig bones, cells and body fluids. The lack or excess of calcium and phosphorus in pig feed will cause adverse effects on sow production. The long-term lack of calcium and phosphorus in feed will paralyze sows before and after birth. But calcium and phosphorus are equally harmful if they are overdosed for a long time. Too much of these two substances can interfere with the absorption and use of the other. Pig feed is mainly plant feed, which should be supplemented with calcium and phosphorus. The content of calcium and phosphorus in feed is rich, the proportion is suitable, and the utilization rate of digestion and absorption is high. For example, adding fish meal, meat and bone meal can not only meet the protein requirements of pig growth, but also meet the needs of calcium and phosphorus. At present, there are several kinds of feeds that can supplement calcium and phosphorus of pigs.
        2.1 bone meal
        骨粉是通過脫脂、干燥和粉碎牲畜骨頭制成的。由于骨粉主要由鈣和磷組成,骨粉可以補充鈣和磷。骨粉中鈣的含量大約是磷的1.5 - -2.0倍,和鈣和磷的比例適用于豬的需求,這是一個很好的飼料和均衡的鈣和磷的比例,其中鈣的含量約占30.12%,磷的比例約占13.46%。
        Bone meal is made by degreasing, drying and crushing livestock bones. Because bone meal is mainly composed of calcium and phosphorus, bone meal can supplement calcium and phosphorus. The content of calcium in bone meal is about 1.5-2.0 times that of phosphorus, and the proportion of calcium and phosphorus is suitable for the needs of pigs, which is a good feed and a balanced proportion of calcium and phosphorus, in which the content of calcium accounts for about 30.12% and the proportion of phosphorus accounts for about 13.46%.
        2.2 eggshell and shell powder
        The eggshell and the egg powder are made by grinding the fresh eggshell and the eggshell after drying. The content of calcium in eggshell powder is more than 30%. The main component of shell powder is calcium carbonate, and the content of calcium is more than 30%. Eggshell and shell powder can only be used as supplementary feed for calcium.
        2.3 calcium Hydrophosphate
        Dicalcium phosphate is also known as Dicalcium Phosphate. Its components are mainly phosphorus and calcium, generally containing more than 18% phosphorus and 23% calcium. Dicalcium phosphate supplementation has a good effect on calcium and phosphorus in pigs.
