Feed additive for healthy breeding of piglets

Abstract

The invention provides a feed additive for healthy breeding of piglets. The feed additive is prepared according to a method comprising the following steps: 1) taking bean pulp as a raw material, adding compound bacteria of bacillus natto and lactobacillus acidophilus, fermenting in a fluid medium for 40-56 hours at a fermentation temperature of 25-37 DEG C, and then centrifugally filtering to obtain fermentation liquor; 2) successively using papain, peptidase and alkaline protease for performing enzymatic hydrolysis on the fermentation liquor acquired in step 1), and centrifugally filtering after the end of enzymatic hydrolysis to obtain a supernate; 3) adding cinnabar and Chinsese date extract into the supernate acquired in step 2) to obtain mixed liquor, wherein the additive amount of cinnabar is 0.02-0.13% of the weight of supernate and the additive amount of Chinsese date extract is 0.58-1.32% of the weight of supernate; 4) vacuum-drying the mixed liquor acquired in step 3). The feed additive is capable of improving gastrointestinal flora of piglets, boosting immunity of piglets and eliminating iron-deficiency anemia diseases.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a feed additive for healthy breeding of suckling piglets. Background technique [0002] Piglets refer to piglets from birth to 30 kg. The digestive function of piglets is not perfect. Even if the feed contains enough nutrients, piglets cannot absorb them, resulting in a lot of waste of feed and increased Breeding costs; and the immunity of suckling piglets is low, often a sick suckling piglet will cause the whole pig house to be infected, causing great economic losses. Treatment is often too late. In addition, due to the low iron concentration in breast milk and the inability to meet the needs of piglets, piglets often suffer from iron deficiency anemia during the feeding process, which in turn affects piglets’ appetite and reduces their immunity, leading to the occurrence of other diseases, thereby bringing economic benefits. loss.

[0002] Piglets refer to piglets from birth to 30 kg. The digestive function of piglets is not perfect. Even if the feed contains enough nutrients, piglets cannot absorb them, resulting in a lot of waste of feed and increased Breeding costs; and the immunity of suckling piglets is low, often a sick suckling piglet will cause the whole pig house to be infected, causing great economic losses. Treatment is often too late

In addition, due to the low iron concentration in breast milk, which cannot meet the needs of piglets, piglets often suffer from iron deficiency anemia during feeding, which in turn affects piglets’ appetite and reduces their immunity, leading to other diseases, which brings economic benefits. loss

[0003] How to fundamentally enhance the immunity of suckling piglets? People have made various attempts. Adding drugs to the feed is a common method. Chemical drugs will cause a large amount of residues in pork, which is not accepted by people. A low-cost and high-efficiency method, but there is still the problem of increased costs caused by poor absorption by suckling piglets
