The invention provides application of an organic iron source in preparation of feed or medicine for relieving chicken eimeria tenella disease, and relates to the technical field of feed additives and veterinary drugs. The organic iron source comprises one of a soybean protein iron chelate, a glycine iron complex and a methionine iron chelate. The feed or the medicine has at least one of the following functions: (1) the content of immune globulins IgA, IgG and IgM in chicken serum infected by eimeria tenella is increased; (2) reducing the expression level of the appendicular factors of the appendicular factors after the appendicular factors are infected by the eimeria tenella, wherein the appendicular factors of the appendicular factors comprise IL-1beta, IL-8, TNF-alpha and IFN-gamma; (3) the death rate of the chicken infected by eimeria tenella is reduced; (4) increasing the weight of the chicken infected by eimeria tenella; and (5) reducing the cecum lesion score of the chicken infected by the eimeria tenella.

The invention discloses magnetic biochar as well as a preparation method and application thereof. The preparation method comprises the following steps: calcining agricultural wastes containing organic matters to obtain a biochar initial material; soaking the biochar initial material in a mixed solution containing an iron source, a reducing agent and an alkalinity regulator; and then carrying out hydrothermal reaction. The biochar precursor is prepared from agricultural wastes containing organic matters, such as comprehensive solid particles in aquaculture tail water, and complex components and original characteristics of the biochar precursor are reserved to the greatest extent. Meanwhile, the biochar is subjected to magnetic functional modification, the dual advantages of rapid adsorption and convenient recovery are achieved, and the problem that conventional biochar is difficult to separate, recover and reuse from the water body is solved. According to the method, resource utilization of solid particles in the breeding tail water can be achieved, meanwhile, antibiotic pollutants can be effectively removed, and the spreading risk of drug-resistant bacteria is reduced.

The invention discloses a nano iron oxide and colla corii asini synergistic blood replenishing nutrition formula and a preparation method thereof. The formula comprises the following components: 0.5-3% of surface functionalized nano iron oxide, 0.5-3% of colla corii asini and the balance of water. 30-50% of a donkey-hide gelatin matrix; 0.5 to 2.5% of vitamin C or a vitamin C derivative; 2-7% of plant polysaccharide; 0.5-3% of a licorice extract; 40-55% of ice syrup; the preparation method comprises the following steps: dissolving the donkey-hide gelatin matrix, adding the premixed nano iron oxide and vitamin C derivative, carrying out ultrasonic dispersion, sequentially adding other components, and carrying out homogenization treatment. According to the invention, sodium citrate or gelatin-coated nano iron oxide is used as a high-efficiency iron source and is matched with the blood replenishing effect of donkey-hide gelatin to realize function synergy; the bioavailability of iron is remarkably improved through the compatibility of vitamin C and polysaccharide; the nutritional powder has the advantages of traditional nourishing and modern nutritional supplement, and can be prepared into various dosage forms such as paste and soft sweets. In addition, the in-vitro absorption rate is 1.8-2.5 times of that of a traditional iron agent, the gastrointestinal irritation is remarkably reduced, and the iron-containing compound preparation is particularly suitable for nutrition intervention of people suffering from iron-deficiency anemia.

The invention discloses ruddy heme iron red ginseng and donkey-hide gelatin nutritional milk powder and a preparation method thereof, and belongs to the technical field of milk powder, the ruddy heme iron red ginseng and donkey-hide gelatin nutritional milk powder comprises the following components in parts by mass: a wet process part: 420-455 parts of whole milk powder, 306-345 parts of dried skim milk, 185-205 parts of isomaltooligosaccharide (type 50) powder, 35-40 parts of polydextrose, 11.5-14.5 parts of a milk powder nutrition enhancer III, 0.3-0.5 part of compound L-carnitine, and 0.1-0.3 part of heme chloride; according to the ruddy heme iron red ginseng and donkey-hide gelatin nutritional milk powder and the preparation method thereof, the heme chloride is adopted as an iron source, the bioavailability of the red heme iron red ginseng and donkey-hide gelatin nutritional milk powder is remarkably higher than that of ferrous sulfate used in traditional iron-supplementing milk powder, meanwhile, through beta-cyclodextrin embedding treatment, the fishy smell problem of an iron agent is solved, gastrointestinal tract stimulation is avoided, and L-sodium ascorbate is matched, so that the nutrition of the milk powder is improved. And the iron absorption rate can be further improved.

A bite-sized nutritional composition comprising an iron source, at least one vitamin and chocolate, wherein the iron source is in the form of a microencapsulated iron. A nutritional composition suitab

The application provides a lactation material for increasing iron content in sow milk, and relates to the field of agricultural technology. The raw material of the lactation material comprises the following components in parts by mass: 2-3 parts of an iron source, 5-8 parts of fermentation material, and 0.8-1.0 parts of eugenol; the fermentation material is prepared by fermenting wheat bran and soybean meal with Bacillus polymyxa; and the iron source is a composite iron source composed of glycine ferrous, methionine ferrous and fumarate ferrous. The lactation material can significantly improve the iron content in the milk of sows in the lactation period, ensure the iron demand of piglets, and improve the survival rate of piglets, birth weight and weaning weight, and ensure the health of piglets, under the condition of a small amount of addition in the daily ration.
