Feed preference and feeding behavior of different mouse species in laboratory housing

The feed preference of two species wild mice, the house mouse (Mus musculus), and mound-building spicilegus) was investigated (kept in our laboratory for 25 generations). Our interest focused on (i.e. if mice choose type closest to their natural food). proximate composition granulated feeds offered differed minimally; crude fat fibre content mixture higher, only this contained insect protein. Based obtained results, both approached more frequently than other feeds. same tendency observed consumption where animals mostly consumed mixture. During 5-day long study, increased continuously, while decreased significantly. average also influenced by room temperature. studies can help develop optimized indoor keeping breeding small domesticated mammals.
