Technical Field

The invention belongs to the technical field of livestock and poultry breeding, and relates to a nonreactive fully-puffed suckling pig creep compound feed and a preparation method thereof.

Background

The weaning stage of the piglets is one of the key time periods in the pig raising production process, and the piglets face stresses in various aspects such as nutrition, environment, swinery 'social contact' and the like. Because the immune and digestive absorption systems of the weaned piglets are not developed completely, the weaned piglets are easy to have diarrhea, the death rate is increased, the feed intake is reduced, the weight gain is slow and the like, and great economic loss is brought to the pig farm cultivation. Antibiotics have generally been used to prevent and treat diarrhea in the weaned stage of piglets in the past 20 th century and 50 s, with good results. The antibiotics are used in the feed for the early weaned piglets, so that the propagation of harmful bacteria is effectively inhibited, infectious diseases are controlled, the weaned stress and diarrhea of the piglets are solved, but the long-time addition of the antibiotics can destroy the flora balance in the piglets, so that the flora disturbance immune function is reduced, the later growth and development of the piglets are influenced, and meanwhile, the problem of drug resistance caused by the antibiotics is a biological safety problem. Therefore, antibiotic substitution is inevitable in piglet feed.

The 'feed resistance prohibition' is comprehensively executed in 2020, and the challenges of reducing the growth performance of piglets in a pig farm, increasing the fatality rate, increasing the workload of workers, improving the breeding cost and the like are expected. At present, the research of the antibiotic-free suckling pig creep compound feed mainly comprises the selection and treatment of raw materials, the optimization of a formula and the innovation of a processing technology.

CN107927384A discloses an antibiotic-free and dust-free suckling pig creep compound feed and a preparation method thereof, wherein the feed is prepared from the following components: corn, fermented corn, soybean meal, fermented soybean meal, expanded corn meal, imported fish meal, plasma protein powder, dried intestine, whey powder, soybean oil, cane sugar, molasses, sodium glutamate, a phagostimulant, Yibao phospholipid, yeast hydrolysate, an acidifier, stone powder, calcium hydrophosphate, salt, 98.5% lysine, 98.5% threonine, 10% tryptophan, special compound enzyme for piglets, phytase, a microecological preparation, a Chinese herbal medicine health-care agent, antibacterial peptide, an immunopotentiator, 50% choline chloride and a premix; the preparation method comprises the steps of preparing a granular material product and a powder material product respectively, and then mixing the granular material product and the powder material product to obtain the antibiotic-free and dust-free suckling pig creep compound feed. This patent application, although not supplemented with antibiotics, fails to completely eliminate feed raw material antigens; CN102885236A discloses an antibiotic-free health powdered suckling pig creep compound feed and a preparation method thereof, wherein the feed is prepared from the following raw materials: corn, broken rice, puffed corn flour, puffed soybean meal, peeled soybean meal, fermented soybean meal, white fish meal, flour, plasma protein powder, whey powder, fructose, dextrose monohydrate, soybean oil, calcium formate, calcium dihydrogen phosphate, salt, an envelope slow-release acidifier, choline chloride, a suckling pig compound premix, zinc oxide, yeast cell wall polysaccharide, sodium glutamate, arazyme, lipase, clostridium butyricum, plant essential oil, L-lysine hydrochloride, DL methionine, L-threonine, tryptophan and phytase; according to the application, health care is carried out through clostridium butyricum and various plant essential oils, but the effect is not good enough, partial loss of an anti-additive is caused in the processing process, and nutrient substances such as electrolytes, vitamins and amino acids in piglets are easily lost along with diarrhea due to a series of changes and stresses such as nutrition, weaning, material changing and house transferring after the weaning of the piglets, so that the piglets are dehydrated, lean and even die.

Therefore, a new creep compound feed for piglets needs to be developed, which is free of antibiotics and can improve the problems of nutrient digestion and absorption, intestinal health and the like of weaned piglets.

Disclosure of Invention

The invention aims to provide the nonreactive fully-puffed suckling pig creep compound feed and the preparation method thereof, and the suckling pig creep compound feed provided by the invention can effectively improve the intestinal health of weaned pigs, further reduce diarrhea and reduce the death rate; and the feed intake can be increased, the nutrient absorption is promoted, and the purpose of rapid weight gain is achieved.
