Antibiotic-free suckling pig conservation feed containing compound enzyme and preparation method thereof

Abstract

The invention relates to the technical field of livestock and poultry feeds, and particularly discloses an antibiotic-free suckling pig conservation feed containing compound enzymes and a preparationmethod thereof. The conservation material comprises corn, soybean meal, wheat bran, barley, low-protein whey powder, vegetable oil, antibacterial peptide, active lactic acid bacteria powder, bacilluspowder and clostridium butyricum powder; herein, the plant raw materials are steamed and cooked by high-temperature steam and then are subjected to solid-state oxygen-consuming fermentation by aspergillus oryzae; wherein the vegetable raw materials are subjected to curing and in-vitro pre-digestion through cooking and fermentation, so that the tissue structure and anti-nutritional factors of the vegetable raw materials are effectively damaged, and the problem that weaned piglets are difficult to digest is solved. The conservation feed does not contain antibiotic, high-copper, high-zinc and other anti-diarrhea substances, and by adding antibacterial peptide, probiotics and other green and environment-friendly substances, the problem of bacterial pathogenic bacteria diarrhea of weaned pigs can be effectively prevented and relieved. According to the preparation method, granules are formed in a wet mixing manner, and then low-temperature drying is performed, so that the activity of variousenzyme systems and heat-sensitive raw materials are prevented from being damaged.

Description

technical field [0001] The invention relates to nursery feed and a preparation method thereof, belonging to the technical field of livestock and poultry feed, in particular to a nursery feed containing compound enzymes and an anti-resistant suckling pig and a preparation method thereof. Background technique [0002] After weaning, the activities of protease, amylase, lipase, etc. of piglets all decreased significantly, and could only return to the pre-weaning level after two weeks of weaning; when weaning, the digestibility of protein, starch, fat, etc. Intestinal fermentation, causing diarrhea in piglets. At present, the nursery feed for suckling pigs has the following problems: (1) The raw materials used are mostly animal raw materials with high digestibility, or plant raw materials that have undergone simple pre-digestion or physical and chemical treatment, such as soybean protein concentrate, fish meal, and expanded soybean , wheat hydrolyzed protein, etc., but the dige...

Problems solved by technology

[0004] In view of the shortcomings of the above-mentioned prior art, the object of the present invention is to provide a nursery feed containing compound enzymes without resistance to suckling pigs and a preparation method thereof, aiming to solve the problem of poor digestion and absorption of the existing nursery feeds, and the high digestibility of animal properties. The phenomenon of high dependence on raw material protein solves the problems of diarrhea, intestinal damage, drug resistance, slow growth and other problems caused by piglets eating the existing nursery feed
