Effects of different tropical forages on growing and morphological traits of Yunnan geese

Effects of three different tropical forages including Lolium multiflorum, Cichorium intybus, and Pennisetum purpureum, on growth of Yunnan geese were studied by making compound feed as control, and using the analysis frame of traditional morphology biology. Results showed that 1) Yunnan geeses physical growth, chest growth, muscle growth, and leg growth were similar under four diet treatments, but geese feed with P.purpureum, C.intybus, and compound feed had a better backside growth than others, and those feed with P.purpureum grew best; 2) During the test, Yunnan geeses feed with L.multiflorum and C.intybus had a similar daily gain and diet to gain ratio, and both of these two indexes were higher than those of Yunnan geeses feed with P.purpureum and compound feed; 3) Yunnan geese grew up with a pattern of fastslowfast under effects of four different diets. These effects were emerged on geese younger than 75 days old, and not be found in geese who were older than 75 days; 4) Refer to the production efficiency, L.multiflorum and C.intybus were fit to be used in feeding of Yunnan geese. Besides, L.multiflorum had a particular effect on the average daily gain of Yunnan geese who were 30 to 50 days old. P.purpureum was not fit to be used individually in feeding of Yunnan geese.
