The invention belongs to the field of leather processing, and specifically discloses a degreasing method for sturgeon leather. The invention aims at the fat distribution characteristics of sturgeon skin, and selects different degreasing agents and degreasing methods for different oil components in different tanning processes. Degrease separately, the degreased sturgeon leather is clean and tidy, suitable for the dyeing requirements of various colors of sturgeon leather, the color is full and bright; the tanned and degreased leather has been tested and found to be lead-free. At the same time, 168 substances of very high concern (SVHC ) for screening tests, the concentration of the substance is less than 0.1%, which is easy to promote in the market.

The present invention relates to a pork intramuscular fat content nondestructive testing method based on computer vision. The method comprises the steps of adopting a camera calibration method to calibrate a CCD digital camera, selecting the pork musculi oculi just now purchased from a slaughter house as an experiment sample, shooting and sampling the cross-section of the pork musculi oculi, carrying out the pre-processing on an obtained sample image via an improved sample block repair method, and recovering the original information of a light reflection area of the image; combining a maximum entropy method and an iteration method to carry out the image segmentation on the pre-processed musculi oculi image, and extracting the pork marbling; extracting 291 characteristic values, such as a fat number index, a fat distribution index, a fat texture index, etc., from an obtained marbling image, establishing a pork intramuscular fat content prediction model according to the characteristic values and a chemical method detection result, and finally predicting the pork intramuscular fat content via the model. By utilizing the method of the present invention, the pork intramuscular fat content can be predicted very well, and the pork nutrition detection is more objective, more accurate and more efficient.

The invention discloses a veterinary medicine for enhancing porcine growth performance and a preparation method thereof. The veterinary medicine for enhancing porcine growth performance is prepared from the following active pharmaceutical ingredients in parts by weight: 5-25 parts of aniseed, 5-25 parts of fennel, 5-25 parts of cinnamon, 5-25 parts of creat, 5-25 parts of tsaoko and 5-25 parts of radix bupleuri. The preparation method comprises the following steps: cleaning the required active pharmaceutical ingredients, sequentially drying and pulverizing to obtain medicinal powders of the active pharmaceutical ingredients; and weighing the pulverized medicinal powders of the active pharmaceutical ingredients according to the proportions of the veterinary medicine, mixing the medicinal powders of the active pharmaceutical ingredients, thoroughly and uniformly mixing, and finally, packaging. By stimulating the secretion of growth hormones, the veterinary medicine enhances the action of the growth hormones, thereby promoting the growth, enhancing the feed conversion rate, lowering the cost and increasing the pig-breeding benefit; the invention lowers the morbidity of respiratory diseases by enhancing the utilization ratio of proteins, lowering the concentration of ammonia gas and improving the breeding environment; and by improving the fat distribution, the invention reduces the deposition of subcutaneous fat, obviously improves the body shape of the pig, and enhances the body lean meat percentage by more than 15%.
