Swine feed additive and preparation method thereof

Abstract

The invention is a swine feed additive and a preparation method thereof, and relates to a nutritional additive in swine feeds and a preparation method thereof. The invention aims to solve deficiencies existing in present swine breeding and provide the swine feed additive and the preparation method thereof. The swine feed additive ensures growth nutritional needs of the swine in a fattening stage. The swine feed additive comprises the following components: 50 to 100 grams of dryopteris setosa, 100 to 150 grams of rhizoma atractylodis, 100 to 200 grams of bitter orange, 50 to 100 grams of ash bark, 50 to 100 grams of cortex mori, 50 to 100 grams of perillaseed, 1000 to 1500 grams of artificial mineral spring salt and 1500 to 2000 grams of distiller's yeast. The preparation method comprises drying the traditional Chinese medicine in sunshine, grinding into powder, and adding the artificial salt and the distiller's yeast to uniformly mix. The swine weighing 30 to 60 kilograms are fed with 50 grams of the additive per day, and the swine weighing 60 to 100 kilograms are fed with 70 grams of the additive per day. Weight of the swine can be increased by 30 to 40 % and a utilization rate of the feed can be increased by 15 to 20 % if the swine are fed at dinners.

Description

technical field [0001] The invention relates to an animal feed additive, in particular to a nutritional additive in pig feed and a preparation method thereof. technical background [0002] In the breeding process, it is not only necessary to ensure the growth rate and survival rate of pigs at various stages, but also to reduce the drug residues in the process of feed utilization. Therefore, the requirements for the composition of the feed should be implemented in accordance with the standards to avoid adverse effects on the human body and the environment. . Most of the existing feed additives use hormones to promote the growth of pigs, but they cannot be adjusted and supplemented according to the various production stages of pigs, and the immune system of pigs cannot be improved, which affects the survival rate of their breeding. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the shortcomings in the existing pig breeding, and to provide...

Problems solved by technology

Most of the existing feed additives use hormones to promote the growth of pigs, but they cannot carry out targeted nutritional adjustments and supplements according to the various production stages of pigs. The immune system of pigs has not been improved, which affects the survival rate of their breeding.
