Abstract

The invention discloses a green, antibiotic-free and low-heavy-metal-emission piglet premix feed additive and a preparation method thereof. The feed additive is composed of artemisia apiacea powder, moutan bark, medicated leaven, scorched hawthorn fruit, roasted malt, purslane, kadsura coccinea leaf, tryptophan, phenylalanine, tyrosine, high-purity nano-zinc oxide, peony seed oil and a carrier, wherein the carrier is any one or a mixture of montmorillonite and medical stone in any proportion. The premix feed additive disclosed by the invention only needs to be added into a feed in a trace amount, so that the feed conversion rate of piglets can be effectively reduced, the feed conversion rate is promoted, the oxidation resistance of the piglets is improved, the intestinal microbial polymorphism of the piglets is improved, the diarrhea rate of the piglets and the content of heavy metals in excrement are reduced, the intestinal inflammation of the piglets is effectively controlled, bacteria are inhibited, insects are expelled, and digestion is promoted; the premix feed additive is safe in raw material source, free of side effects and free of pollution to the environment.

Description

Technical field [0001] The invention belongs to the technical field of piglet feed, and more specifically relates to a green premix feed additive for piglets without anti-low heavy metal emission, and also relates to a preparation method of a green premix feed additive for piglets without anti-low heavy metal emission. Background technique [0002] Complete feed is not suitable for transportation cost control and long-term storage. Therefore, the use of compound feed and feed additives has gradually replaced complete feed in recent years. Aromatic amino acids (including tyrosine, phenylalanine, and tryptophan) are allosteric agonists of intestinal CaSR receptors. Three aromatic amino acids in a suitable ratio can recruit β-arrestin2 inhibition by activating the CaSR signaling pathway The NF-κB signaling pathway blocks inflammatory signal transduction and increases the expression of anti-inflammatory factor IL10, thereby having anti-inflammatory effects (Mine, Yoshinori, Zhang, Hu...
