Abstract
The invention belongs to the technical field of livestock feed, and particularly relates to an antibiotic-free and zinc oxide-free livestock feed and application thereof. The invention provides the livestock feed without antibiotics and zinc oxide, which can still improve the nonspecific immunity of livestock and greatly reduce the incidence of diarrhea on the premise of not using antibiotics and zinc oxide. The results of the examples show that the feed provided by the invention can effectively improve the nonspecific resistance of livestock and reduce the positive rate of viruses such as pseudorabies, blue ear, foot-and-mouth disease and the like fed into the livestock; meanwhile, the diarrhea rate of livestock and poultry can be obviously reduced, the daily gain is increased, the material-weight ratio is reduced, and the economic benefit is improved.
Description
Technical Field
The invention belongs to the technical field of livestock feed, and particularly relates to an antibiotic-free and zinc oxide-free livestock feed and application thereof.
Background
At present, the breeding industry generally carries out large-scale breeding, once the bred livestock suffers from infectious diseases, the epidemic situation is easy to spread in a large range, and further, the economy is damaged. Therefore, the breeding industry generally has the action of using antibiotics. The use of large amount of antibiotics can not only play a role in preventing and treating infectious diseases, but also the price of the livestock antibiotics is lower than that of special drugs, so the raising cost can be reduced, and therefore, some bad merchants can misuse the antibiotics for farmers who have no precautionary consciousness to use large amount of antibiotics in order to save the breeding cost or have insufficient related knowledge reserves. However, not only can the misuse of antibiotics interfere with the balance of intestinal flora of the raised livestock, but also the situation that antibiotics which cannot be excreted are left in the livestock body to cause harm to eaters occurs. Therefore, the research and development of antibiotic-free feed is a technical problem which is urgently needed to be solved by the existing breeding industry. Especially, the countries forbid the use of the feed antibiotics from 7 months in 2020. In the culture process, various infectious diseases are prevented and treated only by vaccination, the species are not comprehensive, and the prevention strength is not enough, so that the morbidity, diarrhea rate and mortality of various infectious diseases are greatly increased. In addition, the African swine fever virus has complete outbreak, no effective vaccine exists, and the breeding industry is at present stranded.
Meanwhile, in the existing breeding industry, zinc which is far more than the absorbable amount of livestock is added into the feed to avoid the diarrhea phenomenon of the livestock. The intestinal tracts of the livestock cannot absorb excessive zinc element, so that the excessive zinc element can be discharged along with the excrement, and the livestock excrement cannot be reused as an organic fertilizer raw material due to the overhigh zinc content, and the soil pollution can be caused when the livestock excrement is buried in the soil. Therefore, reducing the zinc content in feed is a major direction in feed development.
