8results about How to "Increase milk production" patented technology

This invention discloses an organic trace element complex for lactating dairy cows, comprising the following components in parts by weight: 40-70 parts of hydroxymethionine complex, 0.1-0.2 parts of sodium iodide, 30-45 parts of yeast selenium, 0.1-0.2 parts of cobalt sulfate, 10-25 parts of synergist, and 5-10 parts of carrier. This invention also discloses the preparation method and application of the above-mentioned organic trace element complex. When used in lactating dairy cows, the various hydroxymethionine complexes can effectively pass through the rumen to the small intestine and be absorbed through amino acid channels, meeting the needs of dairy cows for various trace elements during lactation. The synergistic effect of the various hydroxymethionine complexes and the synergist can improve the lactation performance of dairy cows, increase milk production, enhance the body's resistance, significantly reduce the incidence of mastitis and hoof diseases, and alleviate ketosis.

This invention discloses a lactation-promoting composition containing a lime flavonoid extract, comprising, by weight, the following raw material components: 10-50 parts lime flavonoid extract, 5-30 parts synergistic active ingredients, and 20-85 parts excipients; wherein the lime flavonoid extract contains ≥80% total flavonoids (calculated as hesperidin), of which hesperidin ≥40%, neohesperidin ≥15%, naringin ≥10%, and hesperidin ≥5%. Using the lime flavonoid extract as the core, it achieves highly efficient lactation promotion through multi-target synergistic effects. In livestock applications, it can increase milk yield in dairy cows by 15%-28% and milk yield in sows by 20%-38%, while significantly improving milk fat, milk protein, and other milk nutritional indicators.

The invention relates to the technical field of traditional Chinese medicine, in particular to a traditional Chinese medicine composition for relieving animal heat stress and a preparation method and application thereof. The composition is prepared from talc, herba elsholtziae, radix scutellariae, rhizoma phragmitis, radix scrophulariae, radix trichosanthis, fructus gardeniae, semen coicis, pericarpium citri reticulatae and liquorice. According to a traditional Chinese medicine compatibility theory, the ten medicinal materials are reasonably combined according to a certain proportion, the obtained composition can effectively relieve heat stress reaction of animals caused by a high-temperature environment, the lactation level of dairy cows is remarkably improved, the milk quality is improved, good adaptability is shown in practical application, the composition is suitable for various breeding scenes, and the breeding efficiency is improved. And a reliable guarantee is provided for animal health.

The application discloses a system for predicting the occurrence time of the peak value of the non-esterified fatty acid concentration in the blood of a dairy cow after delivery, and belongs to the technical field of healthy breeding of dairy cows. The system takes the genus level relative abundance of five marker microorganisms in the intestinal contents of a dairy cow one week before delivery as input data, calculates a score through a preset discriminant model, and judges whether the peak value of the blood free fatty acid concentration after delivery occurs on the day of calving according to a set threshold. The overall prediction accuracy of the discriminant model reaches 90%, the prediction accuracy for dairy cows with a peak on the day of calving reaches 75%, the system is simple to operate and stable in performance, can realize pre-delivery early warning of high health risks of peripartum dairy cows, provides technical support for taking preventive measures in advance, improving the postpartum health status and lactation level of dairy cows, and has important practical application value and economic significance.

The invention relates to the field of additives, and discloses a probiotic fermented feed additive for replacing antibiotics to improve the milk yield of dairy cows, and the probiotic fermented feed additive comprises 70-95% of a symbiotic fermentation substrate. 1% to 10% of saccharomyces cerevisiae; 1% to 10% of lactobacillus plantarum; 1% to 5% of bacillus subtilis; 1% to 5% of propionibacterium propionate; the symbiotic fermentation substrate comprises trehalose, glycerol, bacterial exopolysaccharide and organic acid; mycose derived from the symbiotic fermentation substrate is physiologically enriched in cytoplasm of the lactobacillus plantarum, the organic acid in the symbiotic fermentation substrate comprises propionic acid and lactic acid, and the weight ratio of the propionic acid to the lactic acid is between 1.1: 1 and 5: 1. The additive is used for cow breeding instead of antibiotics, the problems of food safety risks and bacterial drug resistance caused by antibiotic residues are radically eradicated, and meanwhile, multiple probiotics such as saccharomyces cerevisiae and lactobacillus plantarum are scientifically proportioned and have a synergistic effect with a symbiotic fermentation substrate.

The invention relates to the technical field of animal husbandry, and discloses a temperature-sensitive sustained-release gel for treating cow mastitis and a preparation method thereof.The temperature-sensitive sustained-release gel is prepared from, by mass, 15%-24% of a triblock copolymer PLGA-PEG-PLGA solution, 3-7 parts of eucommia ulmoides powder, 2-5 parts of nisin, 1-3 parts of a stabilizer, 1-3 parts of a pH regulator and the balance water. One-time perfusion can be completed under the condition of a small administration volume, a stable sustained-release drug library is formed in the local part of the mammary gland, and the drug is continuously and slowly released through the diffusion effect of the gel layer, so that a lasting inhibition effect is generated on pathogenic bacteria on the surface and in the mammary gland tissue. Due to the fact that the medicine mainly plays a role in the local part of the breast, the high local medicine concentration can be maintained in the breast tissue, diffusion of the medicine to the whole body tissue is reduced, and therefore the risk that the medicine has adverse effects on non-lesion organs or tissues is reduced.

The invention relates to the field of animal husbandry, in particular to a method for improving the production performance of yak milk in a high and cold pasturing area in the grazing and lactation period. The invention provides a mixed feed for improving the production performance of yak milk in a high and cold pasturing area in a grazing and lactation period. The composition comprises a protein feed, a fiber feed and a juicy feed, the mass ratio of the protein feed to the fiber feed to the juicy feed is 2: 5: 3. When the mixed formula feed provided by the invention is used for feeding the yaks in the lactation period under the traditional natural grassland grazing condition in the high and cold pasturing area, the lactation yield and quality of the yaks can be remarkably improved.

The application provides a traditional Chinese medicine compound preparation with a calming effect on cattle, a preparation method and application thereof, and relates to the technical field of traditional Chinese veterinary medicine. The traditional Chinese medicine compound preparation takes Litsea chenii, Spondias axillaris, Polygala, gold button, safflower, mace, clove as core raw materials, is supplemented with bright blue aluminum lake as an indicator, and is prepared by matching a dissolving agent, a thickening agent and deionized water. The traditional Chinese medicine compound preparation has a significant calming effect, and can play a targeted role on different cattle: for new cows, the milk yield can be effectively improved, and the incidence of postpartum diseases can be reduced; for bulls, the number of fighting behaviors can be significantly reduced, and the risk of injury can be reduced; for calves, the weaning stress response can be relieved, the number of weaning period bellowing can be reduced, and the incidence of diarrhea can be reduced. The traditional Chinese medicine compound preparation has the advantages of safety, high efficiency, convenient operation, no skin residue and the like, relies on visual marking to assist in drug administration management, provides a new solution for healthy breeding of large-scale cattle farms, and has a significant application value.
