The invention relates to the technical field of the raising of water buffalos and particularly relates to a water buffalo feed as well as a preparation and application of a water buffalo feed. A basic ration of the water buffalo feed contains the following raw materials: fermented alfalfa, grassiness, fermented manioc waste, broadleaf paspalum, bean pulp and bran. After being fermented, the alfalfa and the manioc waste in the basic ration are capable of softening fibers in the feed and producing enough alcohol fragrance, so that the content of cyanide is decreased, the palatability of the fed is improved, and the basic nutritional requirements of water buffalos in a gestation period can be met. A feed additive contains the following raw materials: a black bean extract, emulsified calcium, calcium citrate, table salt, yeast chromium, malt juice and a soybean extract. According to the water buffalo feed, the estrus rate of unfertilized female water buffalos can be increased, the pregnancy rate can be increased, the fluency rate can be decreased, meanwhile, the daily food intake can be increased, and the nutritional supply of the female water buffalos in the gestation period can be guaranteed.

The invention provides a protocol leading to improved embryo implantation rates and/or decreased miscarriage rates in which hCG, or a bio-analogue, is administered during the follicular phase.

The invention belongs to the technical field of biomedicine, and discloses cells for targeted treatment of habitual abortion and immune infertility and a preparation method of the cells. The preparation method of the cells for the targeted treatment of the habitual abortion and the immune infertility includes the following steps: aseptically drawing about 20 ml of venous blood of a patient husbandor blood relative or unrelated voluntary healthy individual, and performing heparin anticoagulation; under sterile conditions, adding an equal volume of human lymphocyte separation solution to a centrifuge tube, slowly adding the anticoagulant whole blood to the upper layer of the human lymphocyte separation solution, and performing centrifugation at 4 DEG C and 800-1200 rpm in a slow rise and fall manner; and drawing a separated buffy coat by using a pipette, performing washing by using normal saline, performing resuspension, performing centrifugation at 800-1200 rpm, repeating the operationfor 3 times, removing residual serum, red blood cells and the like, preparing a cell suspension with a density of (2-4)x10<7> /ml, and performing temporary storage at 4 DEG C. The cells improve the conception rate, reduce the miscarriage rate, and make the pregnancy success rate reach 70-80% or more.

The invention discloses a traditional Chinese medicine composition for preventing and treating miscarriage of goats. The traditional Chinese medicine composition comprises, by weight, 35-55 grams of radix astragali, 20-35 grams of radix angelicae sinensis, 20-35 grams of parched radix paeoniae alba, 25-40 grams of radix codonopsis, 20-45 grams of rhizoma atractylodis macrocephalae, 20-40 grams of radix glycyrrhizae preparata, 20-40 grams of vinegar-processed folium artemisiae argyi, 20-40 grams of semen cuscutae, 30-50 grams of herba taxilli, 20-40 grams of radix dipsaci, 20-40 grams of radix scutellariae and 30-55 grams of colla corii asini. The traditional Chinese medicine composition for preventing and treating miscarriage of the goats has the advantages that effects of reinforcing qi, nourishing blood, strengthening kidneys for fetus soothing, enhancing disease-resistant mechanisms of the ewes and improving the diathesis of the ewes can be realized from an angle of differentiation of traditional Chinese medicine, and accordingly the purposes of nourishing the qi and the blood, stabilizing uteruses and preventing miscarriage can be achieved; a prevention and treatment combined method is implemented, and accordingly the miscarriage rate of the goats can be reduced by 85% at least.
