An experimental miniature pig rearing cage includes a rearing cage, a support base, and a heater. The rearing cage has a first switch door on its outer side and a second switch door on one side. The lower part of the rearing cage is connected to the support base, and the upper part of the support base has a fixed base. The lower part of the rearing cage has a lying board, and the lower part of the lying board is connected to the fixed base. The lying board has a heating chamber inside, and a heating pipe is connected to the inner side of the heating chamber. The heating pipe passes through the lying board and connects to the heater. The bottom of the heater is connected to the support base. The lower part of the rearing cage has multiple drainage troughs. Before use, the cage is disinfected, improving the survival rate of miniature pigs. The temperature of the miniature pigs' living environment can be adjusted according to needs. The cage is simple to operate, has a reasonable structure, and can achieve centralized collection of feces, reducing the probability of disease in miniature pigs and facilitating their rearing.

The application discloses a method for establishing a Bama miniature pig spleen deficiency and dampness excess model, and belongs to the technical field of animal models. The method is to reduce the immunity of the body by intraperitoneal injection of cyclophosphamide, and then to stimulate the Bama miniature pig by using high-sugar and high-fat feed and senna leaves in combination with a high-humidity external environment. After 8 weeks, the Bama miniature pig has the clinical manifestations of the spleen deficiency and dampness excess, such as body fatness, fatigue and laziness, white and slippery tongue fur, and loose and watery stool, and the model is verified in the reverse direction by using the classic compound Shenglin Bai Zhusan. The Bama miniature pig spleen deficiency and dampness excess model is applied to the research of human spleen deficiency and dampness excess and the development of spleen-invigorating and dampness-expelling drugs. The model provides a new model for standardizing, standardizing and scientifically evaluating the research of spleen-invigorating and dampness-expelling traditional Chinese medicines, and has the advantages of good practicability, strong conformity, simplicity and objectivity, and conforms to the guidance of the theory of traditional Chinese medicine syndromes, and has a wide application prospect.

This invention discloses the application of the AKR1C1 gene and its encoded protein in breeding pig breeds with superior metabolic function. It belongs to the field of genetic engineering technology, and particularly relates to the application of the AKR1C1 gene in breeding pig breeds with superior metabolic function. The nucleotide sequence of the AKR1C1 gene is shown in SEQ ID NO.1. The amino acid sequence of the protein encoded by the AKR1C1 gene is shown in SEQ ID NO.2. This invention provides the AKR1C1 gene of the Guangxi Bama miniature pig, clarifies the nucleotide sequence of the AKR1C1 gene and the amino acid sequence of the encoded protein, and provides the application of the AKR1C1 gene in regulating bile acid metabolism in pig liver, providing a new molecular target for pig genetic breeding and contributing to the breeding of pig breeds with superior metabolic function.
