Technical Field

The invention relates to the technical field of feeds, and particularly relates to a feed additive, a nursery pig feed and a preparation method thereof.

background

Nursery pigs are also known as early weaned piglets. Since the early weaning technology of piglets is applied to the domestic world, the problem of diarrhea of nursery pigs always troubles large-scale pig farms. The diarrhea of the nursery pig is mainly caused by weaning stress, and in the stage, the digestive system and the immune system of the nursery pig belong to the development stage, and all functions are not complete. During weaning, the daily ration of the piglets is changed from breast milk to feed (such as corn-soybean meal type feed), compared with the breast milk, the animal protein which can be digested and absorbed in the feed is reduced, the plant protein with low utilization rate is increased, and certain burden is caused to the digestive tract of the piglets. In addition, the adverse factors such as group transfer feeding and sow leaving can also cause psychological stress to piglets, and the weakness of an immune system causes the piglets not to be capable of normally resisting the attack of pathogenic bacteria such as escherichia coli, so that the problem of diarrhea of nursery pigs cannot be properly solved.

the feeding antibiotics can relieve the diarrhea of nursery pigs and avoid the loss brought to pig farms, but the problems of antibiotics abuse, residues and increased bacterial drug resistance, environmental pollution caused by the antibiotics and the like threaten the life health of human beings, so that the non-antibiotic breeding also becomes the focus of attention of all communities.

therefore, how to find a suitable additive to replace antibiotics in feed without affecting the production performance becomes a technical problem to be solved urgently in the industry.

disclosure of Invention

Based on the above, there is a need to provide a feed additive which can effectively relieve diarrhea caused by early weaning of piglets and can improve the survival rate and growth rate of piglets.

in a first aspect, the embodiment of the invention provides a feed additive, which comprises plant essential oil and Chinese herbal medicine, wherein the plant essential oil contains oregano essential oil, thyme essential oil and celery essential oil, and the Chinese herbal medicine contains pulsatilla chinensis, macleaya cordata, poplar flower, purslane and plantain seed.

In one embodiment, the mass ratio of the plant essential oil to the Chinese herbal medicine is 0.5-1.5: 0.5 to 1.5. Preferably, the mass ratio of the plant essential oil to the Chinese herbal medicines is 1: 1.

in one embodiment, the weight ratio of the oregano essential oil, the thyme essential oil and the celery essential oil in the plant essential oil is 0.1-0.3: 0.04-0.08: 0.02-0.06. Preferably, in the plant essential oil, the mass ratio of the oregano essential oil to the thyme essential oil to the celery essential oil is 0.2: 0.06: 0.04.

in one embodiment, the Chinese herbal medicines comprise the Chinese pulsatilla root, the bock-apple, the poplar flower, the purslane and the plantain seed in a mass ratio of 0.05-0.15: 0.06-0.1: 0.04-0.08: 0.02-0.06: 0.01 to 0.03. Preferably, the mass ratio of the pulsatilla chinensis to the macleaya cordata to the poplar flower to the purslane to the plantain seed is 0.1: 0.08: 0.06: 0.04: 0.02.

The feed additive contains plant essential oil and Chinese herbal medicine preparation, the raw material components are scientifically matched and mutually cooperated, and the feed additive does not contain antibiotics, is safe, green and pollution-free.

In a second aspect, the embodiment of the invention further provides a nursery pig feed, which includes the feed additive described in any one of the above embodiments and a pharmaceutically acceptable adjuvant.

in one embodiment, the auxiliary materials comprise corn, bean pulp, rice bran meal, calcium hydrophosphate, fish meal, soybean oil, salt and nutrient elements, wherein the nutrient elements comprise minerals and vitamins.

in one embodiment, the auxiliary materials comprise, in parts by weight:

60-65 parts of corn;

20-25 parts of soybean meal;

2-4 parts of rice bran meal;

0.5 to 1 portion of calcium hydrophosphate;

3 to 5 parts of fish meal;

0.3 to 0.5 portion of soybean oil;

0.1 to 0.2 portion of salt; and

1 part of nutrient elements.

In one embodiment, the nutrient elements comprise ferrous sulfate, copper sulfate, sodium selenite, potassium iodide, 0.05 part of coated zinc oxide, manganese methionine, vitamin A, vitamin E, vitamin D, vitamin K, riboflavin, biotin, vitamin B12, pantothenic acid, folic acid, nicotinic acid and pyridoxine.

The feed additive in the nursery pig feed contains plant essential oil and Chinese herbal medicine preparations, the raw materials are scientifically matched and cooperated with each other, and the feed additive does not contain antibiotics, is safe, green and pollution-free. Experiments prove that the nursery pig feed can effectively reduce diarrhea frequency, morbidity and mortality of nursery pigs and provide more healthy nursery pig seedlings for pig farms. And the growth rate of the nursery pigs is improved, the slaughtering time is shortened, the feeding period of a pig farm is favorably shortened, and the production batches are improved as much as possible. Can also reduce the feed conversion ratio of nursery pigs and the feeding cost. Compared with the conventional common puffed nursery pig feed, the nursery pig feed does not cause drug resistance of gastrointestinal tract pathogenic bacteria, is convenient for disease treatment and prevention in pig farms, reduces the medication cost and creates higher economic benefit.

in addition, the embodiment of the invention also provides a preparation method of the nursery pig feed, as shown in fig. 1, the method comprises the following steps:

S110, uniformly mixing the solid auxiliary materials according to a mass ratio, and crushing the mixture by using an ultrafine crusher to obtain a first mixture, wherein the first mixture can pass through a sieve of 200-320 mu m;

S120, mixing the first mixture with a feed additive to obtain a second mixture, wherein the feed additive comprises plant essential oil and Chinese herbal medicines;

s130, puffing and granulating the second mixture at high temperature and high pressure to obtain feed particles;

s140, drying the feed particles at 75-80 ℃;

S150, spraying oil to the dried feed particles;

and S160, cooling the oil-sprayed expanded feed to obtain the nursery pig feed.

in one embodiment, the feed for nursery pigs prepared by the method has a crude protein content of 18-19%.

The method for preparing the nursery pig feed can obtain the expanded feed, and the product has the advantages of stable apparent quality, regular cut, low powder content, low powdering rate and uniform color.

In conclusion, the feed additive, the nursery pig feed and the preparation method thereof provided by the invention can be used for preparing the complete feed for the nursery pigs, which uses plant essential oil and Chinese herbal medicines to replace antibiotics, without influencing the intestinal health and growth rate of the nursery pigs. The feed has reasonable formula structure, easily-obtained raw materials, can effectively solve the problem of diarrhea caused by early weaning of piglets, remarkably improves the survival rate and the growth rate of the piglets, can reduce the feeding cost, and brings higher economic benefit for pig farms.
