Sodium chloride added to feed is not salt for animal husbandry, and there is no legal basis, and the standards are different. There are national standards for feed-grade sodium chloride and salt for livestock and poultry, and there is a big difference between the three standards. In terms of health indicators, compared with the salt standard (GB5461-2000), the feed-grade sodium chloride standard (GB/t23880-2009) has added three limit indicators of cadmium and sulfite. From the perspective of main ingredients, there is no iodine in the feed-grade sodium chloride standard, and the iodine content is clearly specified in the standards for table salt and livestock salt. The use of table salt or animal husbandry salt to replace sodium chloride as a feed additive is to disrupt the national legal order and maintain the quality and safety of feed products. The second is to weaken the technical ability to ensure a balanced supply of trace elements in feed. The third is to increase the cost of feed products and ultimately increase the animal Product consumption cost.
If sows and dairy cows do not eat or eat less salt, the milk will be reduced. The feed salt standard will affect the healthy growth of piglets and cowboys; if the salt supply in the layer diet is insufficient, it will reduce body weight and egg weight. Reduce egg production.
