In sows feed, * should be supplemented with sodium, chlorine, calcium, phosphorus and other mineral elements.

　　1、盐

　　1. Salt

　　大多数植物性饲料中氯和钠的含量都很低，所以猪饲料一般都加盐。饲料中钠、氯长期缺乏会影响猪的食欲，影响猪的生长和生产，降低饲料的利用效率。缺盐的猪，常表现为舔猪圈、栏杆、啃土或炉灰等。异物。如果饲料中盐的含量过多，供水不足，就会引起猪盐中毒，主要表现为口渴、紧张、腹泻、体弱、重可引起昏迷和死亡。如果发现猪吃了含盐太多的食物，应该给它们足够的水，并立即用新的食物代替。目前，在我国用于喂猪的饲料中，有鱼粉、肉粉、泔水和酱油渣等含盐较多。因此，在给猪饲喂上述饲料时，应减少猪日粮中盐的添加。在母猪复合饲料中，盐的添加量一般小于0.5%，可以满足猪对钠、氯元素的需求。

　　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.


　　钙和磷

　　Calcium and phosphorus

　　钙和磷是猪骨骼的主要成分，也是细胞和体液的主要成分。猪饲料中钙、磷的不足或过剩会对母猪生产造成不利影响。饲料中钙和磷的长期缺乏会使母猪在出生前和产后瘫痪。但是钙和磷如果长期过量也同样有害。过多的这两种物质会干扰另一种物质的吸收和使用。猪饲料以植物性饲料为主，应补充钙、磷。饲料中钙、磷含量丰富，比例适宜，消化吸收利用率高。如添加鱼粉、肉骨粉等，不仅能满足猪生长对蛋白质的需求，还能满足钙、磷的需求。目前，有几种饲料可以补充猪的钙和磷。

　　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、骨粉、

　　2.1 bone meal

　　骨粉是通过脱脂、干燥和粉碎牲畜骨头制成的。由于骨粉主要由钙和磷组成，骨粉可以补充钙和磷。骨粉中钙的含量大约是磷的1.5 - -2.0倍,和钙和磷的比例适用于猪的需求,这是一个很好的饲料和均衡的钙和磷的比例,其中钙的含量约占30.12%,磷的比例约占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蛋壳和壳粉

　　2.2 eggshell and shell powder

　　蛋壳和蛋粉是将新鲜的蛋壳和蛋壳在干燥后磨碎制成的。蛋壳粉中钙的含量在30%以上。贝壳粉的主要成分是碳酸钙，钙的含量也在30%以上。蛋壳和壳粉只能作为钙的补充饲料。

　　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磷酸氢钙

　　2.3 calcium Hydrophosphate

　　磷酸二钙也被称为磷酸氢钙。其成分主要是磷和钙，一般含磷18%以上，含钙23%以上。补充磷酸二钙对猪钙、磷效果很好。

　　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.
