Some new results on minimum cycle covers are proved. As a consequence, it is obtained that the edges of a bridgeless graph G can be covered by cycles of total length at most |E(G)| + 25 24 (|V (G)| -1), and at most |E(G)| + |V (G)| -1 if G contains no circuit of length 8 or 12.

## Abstract It was conjectured by Fan that if a graph __G__ = (__V,E__) has a nowhere‐zero 3‐flow, then __G__ can be covered by two even subgraphs of total size at most |__V__| + |__E__| ‐ 3. This conjecture is proved in this paper. It is also proved in this paper that the optimum solution of the C
