Creep, early weaned porket feeding and preparation method thereof

Abstract

The invention discloses a creep and an early weaned porket feeding. The early weaned porket feeding comprises the following components by weight part: 350 to 550 parts of Alpha-grain; 0.5 to 1 parts of choline chloride; 50 to 100 parts of peeled soybean meal; 1 to 5 parts of acidulant; 50 to 100 parts of antigen-extracted soybean meal; 0.5 to 0.75 parts of flavouring agent and masking agent; 25 to 75 parts of fish mel; 0.5 to 1 parts of lysine; 0.1 to 0.5 parts of methionine; 0.1 to 0.25 parts of probiotic (lactic acid bacteria and saccharomycetes); 1 to 4 parts of calcium hydrophosphate; 25 to 50 parts of oil meal; and 5 to 10 parts of mountain meal. A preparation method for the feeding includes the following steps: (a) the peeled soybean meal and the grain are first ground, and preferably, all the ground grain sizes can pass through a 40-mesh sieve; (b) the ground grain is cured by adopting a wet extrusion technique; (c) the materials are accurately weighed according to a formula, and the large materials and then the small materials are sequentially added in the mixer and sufficiently mixed; (d) the mixed material is dedusted; (e) the mixed material is palletized under the low temperature of less than 65 DEG C, and the powdery material directly enters the packaging process; (f) a conventional counterflow type feeding cooler is adopted for cooling.

Description

technical field [0001] The invention relates to the technical field of feed for suckling pigs, in particular to a feed for teaching troughs and early weaned suckling pigs and a preparation method thereof. Background technique [0002] Early weaning can improve the reproductive performance of sows and effectively reduce or block the transmission of diseases from sows to suckling pigs. Therefore, with the development of large-scale and intensive pig farming in my country, early weaning technology has been adopted by more and more commercial pigs. awareness and use of the field. However, due to immature digestive system, incomplete digestive enzyme system, insufficient gastric acid secretion, early weaned piglets cannot obtain antibodies from the mother after weaning, and their own active immune system is not perfect, so the feed requirements before and after weaning are particularly high. Although the preparation of feed for early weaned piglets has attracted attention, it is ...

AI Technical Summary

Problems solved by technology

[0005] 3. Relatively poor palatability

[0006] 4. Ignoring the special nutritional needs of early weaned piglets

Early weaning has the characteristics of undeveloped digestive tract and insufficient gastric acid secretion. However, the acidification of the diet has not been paid enough attention to the preparation of diets for early weaned piglets, and there is a lack of special nutrients that promote the development of the digestive tract and enhance the immune function of the intestinal mucosa.

[0007] 5. There are still deficiencies in processing methods

There are two types of feed for suckling pigs: powder and pellets. The disadvantage of powder is that it is easy to grade or generate dust during processing, transportation and feeding, which will affect the feeding effect and even cause respiratory diseases.

The disadvantage of pellets is that the pelleting temperature is too high, which destroys the active ingredients in the feed.
