The method consists of the following steps: (1) selenium-enriched yeasts, plant stalks, fruits, vegetables, mulberry leaves and wheat brans are mixed, and the mixture is fermented to obtain fermentation products; (2) the fermentation products are used to feed grass-eating fly larvae, tenebrio molitor larvae or silkworm larvae to obtain chicken edible pupae; (3) the chicken edible pupas are added into a chicken basic feed to feed chickens and chicken manure produced by the chicken is collected; (4) chicken feathers of the chicken manure are removed, the feather removed chicken manure is dehydrated, and the dehydrated chicken manure is used for feeding grass-eating fly larvae, tenebrio molitor larvae or silkworm larvae to obtain feed pupae; and (5) the feed pupae is separated, the separated feed pupae is dried in a conventional manner, the dried feed pupae is crushed, and the crushed feed pupae is granulated to obtain the selenium-enriched feed additive. The present invention also provides a use of the selenium-enriched feed additive for feeding fish.

The invention relates to the technical field of Chinese brushes, in particular to a drawing Chinese brush and a manufacturing method thereof. The drawing Chinese brush comprises a brush holder and a brush head. The brush head is composed of, by weight, 30%-40% of goat hair, 35%-55% of chicken feathers and 5%-35% of modified straw. The drawing Chinese brush is good in elasticity, high in ink absorbency, soft in texture, and capable of meeting requirements for various drawing styles.

The invention discloses Myceliophthora thermophilia strain and an application thereof in the aspect of producing keratinase, the preservation number of Myceliophthora thermophilia strain GZUIFR-H94.1 is CCTCC NO: M 209140. The method for producing keratinase by the Myceliophthora thermophilia strain GZUIFR-H94.1 takes 20.10g / L of chicken feather powder as carbon source, nitrogen source and inductor, takes 0.98g / L of urea as supplement nitrogen source, and takes 5g / L of NaCl, 6g / L of K2HPO4 and 1g / L of KH2PO4 as enzyme-producing culture medium, wherein, the enzyme-producing temperature is 38 DEG C, the initial pH value is 7.9, and the above materials are continuously cultured for 6 days. The strain can grow fast, is thermophilic, and has stronger keratinase producing ability.
