Antibiotic-free conservation fodder for piglets

Abstract

The invention discloses an antibiotic-free conservation fodder for piglets. The conservation fodder comprises the following components in part by weight: 550-640 parts of maize, 40-60 parts of super steam fish meal, 200-250 parts of peeled soybean meal, 40-60 parts of whey powder, 20-30 parts of glucose, 1-2 parts of table salt, 5-9 parts of secondary calcium phosphate, 10-25 parts of Nengbao, 7-12 parts of calcium formate, 10 parts of premix of the conservation fodder for piglets, 6-11 parts of lysine, 1 part of acidifying agent (coated), premix of vitamins, premix of compound minor elements for piglets, phytase, multienzyme, antibacterial peptide, prebiotics, antioxidant and zeolite powder. The antibiotic-free conservation fodder for piglets does not contain any antibiotics, has no defect of drug resistance of animals, drug residues, environmental pollution and the like, and can rival with or even exceed the antibiotic-contained piglet conservation fodder in the prior art in controlling diarrhea and promoting growth of the piglets.

Description

technical field [0001] The invention relates to a pig feed, in particular to a piglet nursery feed suitable for 42-63 day old piglets. Background technique [0002] Antibiotics can improve the growth performance of animals as a growth promoter, and are widely used as feed additives for livestock and poultry diets, which greatly improves the production level of livestock and poultry. For the purpose of using a large amount of antibiotics in their feed formula. [0003] The extensive use of antibiotics in feed mainly has the following disadvantages: [0004] 1) Adding antibiotics randomly or in excess to the feed will cause antibiotics to accumulate in agricultural and livestock products such as meat, eggs, and milk, and enter the human body through the food chain, causing people to be indirectly exposed to antibiotics every day, resulting in the effect of using antibiotics to treat human diseases disappear. [0005] 2) Antibiotics are easy to produce drug-resistant bacteri...

AI Technical Summary

Problems solved by technology

[0004] 1) Adding antibiotics randomly or in excess to the feed will cause antibiotics to accumulate in agricultural and livestock products such as meat, eggs, and milk, and enter the human body through the food chain, causing people to be indirectly exposed to antibiotics every day, resulting in the effect of using antibiotics to treat human diseases disappear

[0005] 2) Antibiotics are easy to produce drug-resistant bacteria in animals

[0006] 3) Antibiotics destroy intestinal microorganisms. Some microorganisms in the intestinal tract of animals are harmful and many are beneficial. Some vitamins they synthesize are necessary for the human body, but antibiotics will not selectively inhibit or kill them together

Therefore, the abuse of antibiotics will also destroy the balance of intestinal microorganisms in animals, affecting the ability of animals to digest nutrients and the growth performance of animals

[0007] 4) The use of antibiotics in animal feed will affect the immune function of humans

Studies have also proved that chloramphenicol, streptomycin, erythromycin, cephalosporin and polymyxin B can all suppress immune function and weaken the body's resistance

[0008] 5) Some antibiotics are still toxic, such as streptomycin and kanamycin can cause dizziness, tinnitus, deafness; gentamicin, polymyxin, vancomycin, bacitracin can damage the kidneys; some antibiotics can also cause Toxic side effects such as gene mutation, deformity and cancer induction

[0010] CN 102258156 A discloses an antibiotic-free piglet nursery feed and its preparation method. However, although this feed does not contain antibiotics, it still has trace elements: organic trace elements are completely used, and the cost is too high, so it is difficult to apply in practice; the prebiotics are single (Only Bacillus subtilis and lactic acid bacteria), the effect is not significant; the acidifier used is not coated, the amount added is small, and the effect of controlling diarrhea cannot be achieved; the selected compound enzyme lacks amylase and lipase and is not suitable for the physiological stage of piglets and other shortcomings

Therefore, the anti-diarrhea effect and growth rate are not ideal, and the effect of the nursery material with antibiotics cannot be achieved.
