Embodiments of the present disclosure belongs to the technical field of animal feed and provides a method for rapidly evaluating metabolizable energy of goose diet by using a technique of simulative digestion gross energy. By using the technical means combining the biological method and the simulative digestion gross energy technique, metabolizable energy of goose feed can be evaluated quickly. Based on the 'stomach-small intestine' two-step enzymatic methods, it is the first time to establish a regression equation between the metabolizable energy change and fiber level in the cecum to rectify the value of simulative digestion gross energy in the cecal microbial digestion phase, making the simulative digestion gross energy technique more reasonable in the assessment of metabolizable energy in geese. Results show that the use of simulative digestion gross energy technique to assess the metabolizable energy of goose feed value is highly feasible.

The present disclosure discloses a Microcin MccY, and a preparation method and use thereof, wherein the amino acid sequence of the Microcin MccY is GGRGHIAEYFSGPITQVSFYG. Compared with Microcin MccJ25 that only has a bactericidal activity against a small part of serotypes ofsuch as, the Microcin MccY has bacteriostatic/bactericidal effects onLondon, and, and can kill other serotypes ofthat MccJ25 cannot kill. Especially, the Microcin MccY has an outstanding bactericidal effect onandwhich are common in livestock and poultry production, and meanwhile it also has bacteriostatic/bactericidal effects on. Therefore, the Microcin MccY overcomes the shortcoming of the narrow spectrum of the Microcin, has breakthrough significance, and has the potential as a substitute to antibiotics.
