Description
Technical Field
The invention belongs to the technical field of livestock and poultry feed, and particularly relates to concentrated pig feed containing traditional Chinese medicine components.
Background
Pork is the staple food in Chinese diet and accounts for more than 60% of the total consumption of Chinese meat. The factors influencing the pig-raising performance can be summarized into five major factors of variety, feed, management, environment and pig health. Wherein the quality of the feed directly determines the quality of the pork and directly affects the health of the human. Therefore, on the premise of a certain pig variety, the actual result of pig raising is obtained by adding the score of the feed and subtracting the score of management, environment and health factors. In the process of raising pigs, how to select the feed and correctly using the feed becomes the key point of raising pigs. It has been reported that illegal use of illicit drugs such as 'hydrochloric acid clone trole', 'clenbuterol' and the like by some breeders in the Guangdong, Shanghai and the like in the past years results in contamination of pork products. The reports of the overproof use of antibiotics in pig feed are more frequent. Although the state has strict feed safety related laws and regulations, most farmers often choose to feed drugs with dosage exceeding the normal range or add other prohibited drugs in order to save cost and stabilize pork value when facing the problem of diseases of swinery, so that the series of food safety problems inevitably occur and the life health of consumers is harmed.
In addition, at present, a plurality of researchers related to animal husbandry develop pig feed taking traditional Chinese medicines as main ingredients. The traditional Chinese medicine is treasure in China, has a long history and has obvious curative effect. However, most of the traditional Chinese medicine feeds on the market can only prevent and treat a specific disease, do not inherit the concept of 'preventing diseases' in traditional Chinese medicines, and are difficult to popularize and use in animal husbandry due to the fact that the effective time of the traditional Chinese medicines is longer than that of western medicines.
Disclosure of Invention
In view of the above, there is a need to provide a concentrated pig feed containing traditional Chinese medicine components, which aims at the problems of the existing traditional Chinese medicine pig feed. The technical scheme of the invention is as follows:
in a first aspect, the invention provides a pig feed additive containing traditional Chinese medicine components, which comprises a traditional Chinese medicine additive and a probiotic additive, wherein the mass ratio of the traditional Chinese medicine additive to the probiotic additive is (5-10): 1; the traditional Chinese medicine additive comprises the following components in parts by weight: 10-20 parts of honeysuckle, 15-20 parts of dried orange peel, 5-10 parts of poria cocos, 5-15 parts of medicinal fermented mass, 10-20 parts of bighead atractylodes rhizome, 5-10 parts of codonopsis pilosula, 10-15 parts of cinnamon, 3-10 parts of radix isatidis, 3-10 parts of houttuynia cordata and 15-20 parts of negundo chastetree fruit; the probiotic additive is prepared from beer yeast powder, lactobacillus casei powder, aspergillus niger powder and bacillus natto powder according to a mass ratio of 1: 1: 1: 1 addition.
Optionally, the traditional Chinese medicine additive further comprises the following components in parts by weight: 10-15 parts of cyrtomium fortunei, 7-12 parts of dandelion, 4-8 parts of coptis chinensis, 15-25 parts of sweet wormwood and 3-10 parts of ephedra.
In a second aspect, the invention provides a concentrated pig feed containing traditional Chinese medicine components, which comprises the pig feed additive and a special pig feed, wherein the weight percentage of the pig feed additive is 7-8%.
Further, the special feed for the pigs comprises the following components in parts by weight: 200-300 parts of dry corn, 200-300 parts of wheat bran, 100-150 parts of 43% soybean meal, 20-40 parts of puffed full-fat soybean, 10-20 parts of soybean oil, 5-10 parts of calcium hydrophosphate, 5-10 parts of fish meal, 1-2 parts of salt, 1-5 parts of premix, 0.1-0.5 part of vitamin additive and 0.1-0.5 part of trace element additive.
In a third aspect, the present invention provides a method for preparing the above concentrated pig feed, comprising:
step one, preparing traditional Chinese medicine components in the pig feed additive, crushing the traditional Chinese medicine components into particles with the particle size of 2-3 mm, mixing the particles uniformly, adding water with the dry weight 6-8 times of that of the mixture, heating the mixture to a reflux state, decocting the mixture for 2-4 hours, filtering the mixture, and respectively retaining filter residues and filtrate;
step two, concentrating the filtrate to the concentration of 0.7-0.8 g/mL, uniformly mixing the filtrate with the special feed for the pigs after spray drying, and then adding a probiotic additive to obtain a mixed feed;
and step three, drying the filter residue, then crushing the filter residue again to 2-3 mm particles, and uniformly mixing the particles with the mixed feed obtained in the step two to obtain the feed.
In a fourth aspect, the invention provides a pig feeding method, the mixed feed and the concentrated pig feed are obtained by the preparation method, and the method comprises the following steps:
(1) weaning piglets from 7 th day to 25 th day after birth, feeding piglet compound feed, wherein the daily feeding amount is 6-7% of the weight of the piglets, and feeding for 4-5 times;
(2) feeding liquid feed for piglets from the 26 th day to the 28 th day after birth, wherein the feeding amount of the liquid feed is 6-7% of the weight of the piglets every day, and feeding the liquid feed for 5-6 times;
(3) feeding piglets from 29 th to 30 th postnatal age to a mixture of the liquid feed and the mixed feed, wherein the mass ratio of the liquid feed to the mixed feed in the mixture is 1: (1-2), feeding 5-6% of the weight of the piglets in 5-6 times every day;
(4) feeding the piglets from 31 th day to 70 th day after birth with the mixed feed, wherein the daily feeding amount is 5-6% of the weight of the piglets, and the piglets are fed freely;
(5) the adult pigs are fed with the concentrated pig feed with a daily feeding amount of 2-3 kg/day/head, and are fed freely.
Further, the feeding method further comprises the following steps: the concentrated pig feed is fed to the lactating sows, the daily feeding amount is 4.0-4.5 kg/day/head, and the sows can eat the feed freely.
The invention has the advantages and beneficial effects that:
the invention inherits the concept of preventing diseases, can enhance the growth performance of piglets and adult pigs and reduce the inflammation infection rate and the death rate of the piglets by reasonably matching the traditional Chinese medicines and applying the traditional Chinese medicines to the pig feed.
