Feed additive for improving growth of pig

Abstract

The invention relates to a feed additive for improving growth of a pig. The feed additive is characterized by comprising the following components in parts by weight: 2-7 parts of carrot powder, 2-5 parts of common andrographis herb, 4-8 parts of apricot kernels, 1-4 parts of silkworm chrysalis, 2-5 parts of radix glycyrrhizae, 1-3 parts of cinnamon, 1-4 parts of astragalus membranaceus, 1-5 parts of white fish meal, 5-7 parts of amomum tsao-ko, 4-7 parts of phaseolus calcaratus, 3-5 parts of radix bupleuri, 2-6 parts of loaches, 1-3 parts of water stones, 2-5 parts of yeast powder, 4-8 parts of Tibet inula and 2-5 parts of cassia twig. According to the additive provided by the invention, the effect of the growth hormone is enhanced by simulating secretion of the growth hormone; the ammonia concentration is reduced, the feeding environment is improved and the incidence of respiratory diseases is reduced by improving the utilization ratio of proteins; the non-specific immunity of a body is enhanced, the activity of macrophage of the body is activated, the immunocyte level of the body is directly improved, and the anti-infection ability of the body is improved; and subcutaneous fat deposition is reduced and type of figure of pigs is obviously improved by improving fat distribution, so that the carcass lean meat percentage is improved by 15% or more.

Description

technical field [0001] The invention relates to a feed additive for improving pig growth. Background technique [0002] Pigs in the fattening stage will have digestive disorders and other phenomena when factors such as farm environment, pig herd, and feed change, which will cause adverse reactions such as low feed intake and slow growth, which is the cause of low growth performance of pigs One of the main reasons. In addition, in recent years, a large number of antibiotic feeds have been used in pig breeding, and the safety problems caused by antibiotics are increasing. Many countries or regions have passed legislation to restrict or even completely prohibit the use of antibiotics. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to provide a technical scheme of a feed additive for improving growth of pigs. [0004] The feed additive for improving pig growth is characterized in that it comprises t...
