The invention also discloses a preparation method of the water-soluble milk powder for sucking pigs, which comprises the following steps: weighing the components in parts by weight; sequentially adding the components into a mixer and uniformly stirring to obtain the product.
After the puffed broken rice is puffed and processed, a large amount of starch is pasted, starch granules are swelled and cracked, the contents of amylose and amylopectin are reduced, the contents of low-molecular dextrin and reducing sugar are increased, and the digestibility of starch and other nutrients is improved, so that the puffed broken rice is an ideal energy source for feeds for young animals (suckling pigs and weaned piglets). The puffed broken rice is added into the milk powder for the suckling pigs, and has the advantages of good palatability, high digestion and utilization rate, high energy efficiency, promotion of intestinal health of the piglets and the like. After the broken rice is puffed, the starch is gelatinized, the crystal structure of the starch is irreversibly damaged, and the starch quickly absorbs water and swells in the small intestine of animals, so that the hydrolysis speed and the digestion degree of the starch are greatly increased. And secondly, the gelatinized starch has better stability in water and is not easy to precipitate.
Skimmed milk powder, and drying, wherein the fat of fresh milk is reduced to about 1%, and the rest changes little except the fat. The skimmed milk powder is milk white or light yellow, has mild Olibanum and sweet taste, and has no deterioration, scorched flavor or abnormal odor.
Lactose, a disaccharide consisting of glucose and galactose. During the growth and development of infants, lactose not only can provide energy, but also participates in the development process of the brain. It is often added into milk powder for porket to provide energy for porket.
Whey powder is prepared by drying whey which is a byproduct of cheese or casein production. The nutrients in whey are substantially soluble. Such as whey protein, phospholipids, lactose, minerals and vitamins.
Coconut oil, which is the oil extracted from the endosperm of the palm plant coconut after being crushed, dried and steamed; is rich in free fatty acid, caproic acid, palmitic acid, caprylic acid, fatty cerotic acid, capric acid, oleic acid, lauric acid, etc.
The wheat protein hydrolysate has the advantages of high nutrition, low antigen, low allergy, high protein, etc., and can improve the villus form and immunity of the small intestine of young animals.
Lysine, also known as 2, 6-diaminohexanoic acid, is one of the essential amino acids for humans and mammals, which the body cannot synthesize by itself and must be supplemented from food. Lysine is mainly present in animal foods and legumes, and lysine content in cereals is very low. Lysine has positive nutritional significance in promoting growth and development of human beings and mammals, enhancing immunity of organisms, resisting viruses, promoting fat oxidation, relieving anxiety, and the like, can promote absorption of certain nutrients, can act synergistically with the nutrients, and can better exert physiological functions of various nutrients.
The potassium sorbate can inhibit the growth of food-borne microorganisms, has excellent effect of preventing food spoilage, has no obvious influence on the flavor state of food, does not change the characteristics of the food, keeps the original color, aroma and taste of the food, and has small toxicity, safety and reliability. According to the invention, potassium sorbate is added to the milk powder of the suckling pigs instead of citric acid, so that the separation of casein can be effectively avoided, and the water solubility of the milk powder of the suckling pigs is practically improved. Meanwhile, the potassium sorbate can effectively prolong the storage time of the suckling pig milk powder after being brewed.
Preferably, the fat emulsifier is any one or a mixture of two or more of lecithin, apple pomace micropowder and bagasse extract. Further preferably, the fat emulsifier is apple pomace micro powder and bagasse extract according to a mass ratio (1-3): 1 are mixed.
Preferably, the preparation method of the apple pomace micro powder comprises the following steps: washing fresh apple pomace with deionized water, draining, and drying in an oven at 45-60 ℃ for 8-24 hours; then grinding by a low-temperature drying process to obtain apple pomace particles; and then, grinding for 4-24 hours at the speed of 3000-4000 rpm, the grinding solvent of deionized water, the grinding power of 2-4 Kw, the grinding medium of Zeta Beads (0.2-0.6 mm) and the grinding temperature of 10-30 ℃, and then freeze-drying to obtain the apple pomace micropowder.
Preferably, the preparation method of the bagasse extract comprises the following steps: adding 4-6 g of bagasse into 180-230 g of deionized water, heating to 150-170 ℃ from 25 ℃ at a speed of 5-10 ℃/min under the conditions of a nitrogen atmosphere, a rotating speed of 100-200 rpm and an absolute pressure of 0.8-1.5 MPa, and preserving heat at 150-170 ℃ for 15-45 min; naturally cooling to 25 deg.C, filtering, and freeze drying the obtained filtrate to obtain the bagasse extract.
The use method of the water-soluble milk powder for suckling pigs comprises the following steps:
after the suckling pigs eat the colostrums, the product is used, 100g of water-soluble suckling pig milk powder is mixed with warm water at 40-45 ℃ to 1000mL for 0-7 days, and the mixture is stirred uniformly to be fed.
Has the advantages that:
in the prior art, an acidulant, namely citric acid, is often added into milk powder of suckling pigs, so that the acidic environment of intestinal tracts is maintained, and the storage time of the milk powder after soaking is prolonged. However, because a large amount of skimmed milk powder is used in the milk powder, protein casein with high molecular weight is still contained in the skimmed milk powder, and the casein is precipitated under a certain acidic environment, which is related to the content of the casein in the solution and the acidity in the solution. According to the invention, potassium sorbate is adopted to avoid citric acid, so that casein can be effectively prevented from being separated out, and the water solubility of the milk powder for suckling pigs is practically improved; the potassium sorbate can effectively prolong the storage time of the milk powder for sucking pigs after being infused.
