Composite feed additive for supplementing iron and enhancing immunity

Abstract

The invention relates to a composite feed additive for supplementing iron and enhancing immunity, which is mainly characterized in that the composite feed additive is prepared by mixing the following components in parts by weight: 2-8 parts of heme iron and 2-8 parts of immune globulin powder. The composite feed additive is added into a daily ration for pigs according to a ratio of 0.01-0.3%. According to the invention, the unique pure natural biological agents (the heme iron and the immune globulin powder) are used, thus being safe, green and free of any hormone or antibiotic and having other advantages. When being used in the feed industry, the additive can improve the productivity of livestock and poultry; and obvious effects such as iron supplementing, body immunity enhancement and the like can be achieved. When being added into the daily ration, the additive can improve the alimentary and iron-deficiency anemia phenomenon, increase the immune disease resistance of pigs, increase the daily weight gain, increase the survival rate of piglets and reduce the use of medicaments and antibiotics.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a compound feed additive for iron supplementation and immune enhancement. The invention is especially suitable for suckling pigs, early weaned piglets, pregnant sows and lactating sows, and also suitable for various non-ruminant domestic animals and pets. Background technique [0002] Iron is an essential trace element for animals. Iron deficiency in the body can cause nutritional microcytic anemia (iron-deficiency anemia) and affect the body's immunity. Intensive pig farming often results in losses due to piglet iron deficiency anemia. To maintain normal hemoglobin and iron stores in piglets, each pig needs to obtain 7-16 mg of iron per day. If the piglets only rely on breast milk supply, the daily iron intake of piglets is less than 1 mg, and they are prone to anemia. In mild cases, growth is hindered, and in severe cases, they may die suddenly due to hypoxia. In addition, pigl...

Problems solved by technology

Due to various modern advanced feeding management methods, such as intensive pig raising, closed online feeding, early weaning feeding, etc. have been accepted by the majority of pig farmers, some piglets cannot eat colostrum rich in immunoglobulin in time , causing its immunity to decline and its growth to be hindered, so the phenomenon of "stiff pigs" occurs frequently, which brings great economic losses to the pig industry
