On November 17, the Ministry of Agriculture issued a notice on the second round of public solicitation for the revised opinions on the code for the safe use of feed additives. The limited amount of zinc oxide in piglets is the focus of attention. In the revised opinion on September 8, the Ministry of agriculture's Announcement No. 1224 was deleted that "the amount of zinc in the form of zinc oxide in the compound feed of piglets in the first two weeks after weaning shall not exceed 2250mg / kg". If the opinion is passed, the upper limit of zinc in the feed of piglets (< 25kg) is only 150mg / kg. As soon as the amendment was issued, it triggered heated discussions in the industry. After the public solicitation of opinions, experts from the Ministry of agriculture made further modification and improvement on the revised opinions after careful discussion. In this circular,In the first two weeks after weaning, the amount of zinc in the form of zinc oxide in the compound feed should not exceed 1600 mg / kg.This shows that the replacement of high zinc in China will go through a step-by-step process, and animal nutritionists will have enough time to find a perfect alternative to high zinc.
