Ten healthy Tibetan mastiff adults were randomly divided into two groups. The intematianally useful double-pot cultivation design was employed to record the daily feed intake and preferred diet of each Tibetan mastiff, and further to calculate the intake rate. The butter group assumed higher feed intake and intake rate than the chicken fat group (P 〈0.01), and the preferred diet as well (83%). The feed intake and intake rate of chicken fat group was significantly higher than chicken fat and butter ( 1:1 ) combined group ( P 〈 0.01 ). No significant difference was observed in the diet palatability of butter diet to Tibetan mastiff to different plant oil sources ( P 〉 0.05). For various fat level combinations, the diet with highest fat content diet H23 assumed higher feed intake and intake rate than low fat diet H22 and H21 (P 〈0.05). It is concluded that the palatability of butter diet to Tibetan mastiff is higher than chicken fat and its combined diet ( butter:chicken fat = 1:1 ) ; with fat level of 6% - 15%, high fat diet provides Tibetan mastiff a better palatability in comparison with low fat diet.展开更多
