Problems solved by technology

[0003] At present, the research on the breeding of Bama fragrant pigs is mainly focused on the ecological breeding technology of Bama fragrant pigs. There are not many studies on the varieties of Bama fragrant pigs. There are relatively few studies on the treatment of water, and the treatment efficiency of existing treatment technologies is relatively low, which cannot meet the standards of drinking water, causing great pollution to the environment

[0038] 1. Preparation of Crosslinked Chitosan Microspheres

[0039] Dissolve 5g chitosan in 100mL mass fraction of 2% acetic acid solution, stir for 10 minutes, then put it into a three-necked flask, add 50mL deionized water and 2mL mass fraction of 25% glutaraldehyde solution, put the three-necked flask into a water bath at 50°C, and carry out the cross-linking reaction for 4 hours while stirring, wash the cross-linked chitosan gel with deionized water until neutral, dry it, add it to a three-necked flask, add 60 mL of deionized water and Put 10mL of epichlorohydrin solution with a mass fraction of 20%, put the three-neck flask into a 50°C constant temperature water bath, and react for 5 hours. After the reaction, let it cool naturally, filter with suction, and wash the filter residue with acetone and deionized water in sequence To neutrality, dry at 50°C for 24 hours to obtain cross-linked chitosan microspheres.

Abstract

The invention belongs to the field of animal husbandry breeding, and particularly relates to a breeding method of hybrid Bama miniature pigs. The method is characterized by comprising the following steps of 1 mating and 2 pig manure sewage treating. According to the method, the hybrid Bama miniature pigs are bred by adopting wild pigs in the south as male parents and adopting Bama miniature pigs in Guangxi as female parents, therefore, the disease resistance and the pork quality of the Bama miniature pigs can be improved, the survival rate of the Bama miniature pigs can be increased, and the pig variety can be improved; in addition, pig manure sewage is treated by adopting polyaluminium chloride and crosslinked chitosan microspheres, therefore, the COD value, the pH value, the TN value and the TP value of the sewage are greatly decreased, the water quality is improved, the water utilization rate is increased, pollution of the pig manure sewage to the environment is reduced, and meanwhile the breeding cost is greatly reduced.

Description

【Technical field】 [0001] The invention relates to the field of animal husbandry breeding, in particular to a breeding method of hybrid Bama pig. 【Background technique】 [0002] Bama Xiang pig originates from local pigs, originating in Bama Yao Autonomous County, Guangxi, and is known as the "famous nobleman" of pigs. Guangxi Bama is rich in specialties, including Bama hemp, Bama white mud, Bama geomagnetic, Bama fragrant rice, etc. The most famous of which is Bama fragrant pig. Bama pig is a rare and precious local miniature pig breed with a long history of breeding and stable genetics. In March 1995, after Bama was named "Hometown of Chinese Fragrant Pig" by the National Specialty Economic Professional Committee, Bama pig was recorded as a local specialty in history. Bama pigs are wild and precocious in nature, handsome in appearance, short, small, short, and round; they are extensively reared, and have strong adaptability and disease resistance; the largest adult individ...
