Problems solved by technology

The use of high zinc can reduce the diarrhea rate of suckling piglets, but it has a negative impact on the growth and immune function of suckling piglets. First, long-term feeding of high-zinc diets can inhibit the growth of weaned piglets and reduce daily gain; secondly, the diet Adding high zinc in the medium, due to the antagonism between zinc and iron and copper, reduces the absorption of iron and copper, resulting in a significant decrease in hemoglobin content, animal anemia, long-term use leads to the death of a large number of pigs, and affects production efficiency; at the same time, high zinc has a negative impact on the environment The harm of zinc is also very serious. The exogenous zinc that has not been digested and absorbed will be discharged into the environment with feces, so that the soil zinc will accumulate and pollute the environment. At the same time, it will also pollute the groundwater and hinder the sustainable development of animal husbandry.

Embodiment 1

[0023] Example 1: Get 60 parts by weight of nutmeg, 100 parts by weight of red stone fat and 60 parts by weight of poppy shell, mix them, crush them into small pieces, mix and extract 3 times, add water 10 times the weight of the traditional Chinese medicine mixture each time, and reflux for 2 hours , filtered, and the combined filtrates were allowed to stand for later use. Afterwards, the extract is concentrated to a relative density of 1.10-1.2, the concentrated solution is dried, pulverized, and an appropriate amount of starch is added and mixed to make traditional Chinese medicine composition granules for future use.

Embodiment 2

[0024] Example 2: Take 60 parts by weight of nutmeg, 100 parts by weight of red stone fat and 60 parts by weight of poppy shell, mix, pulverize, and pass through a 300-mesh sieve to obtain a Chinese medicine composition powder for future use.

[0025] 1. Experimental determination of the use effect of the feed additive claimed in the present invention in preventing diarrhea in piglets

[0026] Sample selection: Select 1,000 healthy piglets that have just been weaned and have a similar weight, and divide them into five groups: blank group, control group, test 1 group, test 2 group and test 3 group, with 200 pigs in each group, half male and half female, and carried out A trial to prevent diarrhea in piglets. The diet adopts corn-soybean meal based diet, which is formulated according to the nutritional requirements of meat pigs in the United States NRC (1998). The nutritional levels of each treatment group of the tested animals are exactly the same.

Abstract

The invention discloses a feed additive and a preparation method and application thereof. The feed additive is characterized by being prepared from, by weight, 0.4-1.5 wt% of traditional Chinese medicine composition and 2,000 mg / kg of nano-zinc oxide / graphene oxide composite. The feed additive is prepared by evenly mixing the traditional Chinese medicine composition powder or particles and the nano-zinc oxide / graphene oxide composite in proportion. The feed additive is used for treating or preventing intestinal diseases of piglets.

Description

【Technical field】 [0001] The invention relates to the technical field of animal feed, in particular to a feed additive and its preparation method and application. 【Background technique】 [0002] Modern pig raising is mostly based on large-scale production. In order to shorten the lactation period of sows, improve the reproductive performance of sows, and reduce the transmission of diseases between sows and piglets, most large-scale pig farms adopt early weaning technology. However, early weaning will cause stress to piglets, and will also affect the growth and development of piglets, and bring a series of adverse effects, such as diarrhea and other diseases. At present, many scholars at home and abroad suggest using high zinc to alleviate the occurrence of diarrhea in weaned piglets, promote piglet growth, and increase daily weight gain. [0003] Zinc is an essential trace element in animal life activities. It is related to the activities of nearly 300 kinds of enzymes in...
