The invention discloses a method for preparing angiotensin-I-converting enzyme (ACE) inhibitory peptide by using enzymolysis goat milk casein. The method comprises the following steps of: centrifugally degreasing recovered goat milk to obtain skimmed milk; preparing casein by using an isoelectric precipitation method; freezing and drying casein precipitate; dissolving the obtained casein freeze-dried powder to prepare a casein solution; performing hydrolysis on the casein solution by adding different kinds of enzymes; and optimizing the hydrolysis condition and treating a hydrolysis process in an ultrasonic wave mode, so that catalytic activity is improved to ensure that the hydrolysis reaction is complete; and because of the obtained micromolecule ACE inhibitory peptide, obvious pressure reduction function on hypertensive can be achieved, the influence on normal blood pressure is avoided, and the method has the characteristics of no toxic and side effects, high security and easiness for absorption.

The invention discloses lactobacillus plantarum capable of adjusting ampicillin induced intestinal flora disturbance and belongs to the technical field of food. The lactobacillus plantarum CGMCC12436disclosed by the invention is amplification cultured under assistance of skimmed milk, trehalose and saccharose; after being frozen and dried, the lactobacillus plantarum is prepared into a biologicalpreparation; a viable bacterial content of the lactobacillus plantarum CGMCC12436 in the preparation is larger than 109CFU/g. The lactobacillus plantarum CGMCC12436 disclosed by the invention has theadvantages of lower growth generation time, high survival rate in in-vitro simulated gastric fluid and intestinal juice, good adhesion on human HT-29 cells and relatively lower drug resistance in drug allergy testing. The biological preparation prepared from the lactobacillus plantarum has the advantages that ampicillin induced intestinal flora disturbance in a mouse body can be obviously recovered, intestinal functions can be improved and has good market application prospect.

The invention belongs to the technical field of animal breeding, and particularly relates to animal fresh semen low-temperature diluent as well as a preparation method and application thereof. The animal fresh semen low-temperature diluent is prepared from the following ingredients: glucose, sodium citrate, penicillin, streptomycin, enrofloxacin, yolk, defatted milk, vitamin A, vitamin D, vitaminE and water. The diluent has the advantages that Australian white sheep semen is stored for 1 to 2 days in a liquid state form under the condition of low temperature being 0 to 5 DEG C; the artificialinsemination requirement can be reached; the fresh semen storage quality is improved, so that the utilization rate of excellent rams is improved; high nanny goat conception rate is obtained; the problem of long-distance transportation after excellent ram semen collection is solved; the manufacturing method of the diluent is simple; the raw material cost is low; the operability is high; the large-scale popularization and application in the production is convenient.
