Guiminyin in production of geese, effects of feeding the green fodder on growth performance of geese were studied, while P. purpureum K. Scbumacb x P. typhoideum Rich cv. Reyan No. 4 was used as control. The results showed that P. purpureum Schum cv. Guiminyin had high biomass and good nutritional quality, and geese intake of the forage was greater than that of the control variety. The average daily gain was （51.45 ±3.49）g/goose, which was increased by 13.36% compared with control; feed gain ratio was （4.93 ±0.35）%, and feed consumption was reduced by 19.47% compared with control （P 〈0.05）. Thus, it could be concluded that feeding geese with P. purpureum Schum ev. Guiminyin could obtain good economic benefit.展开更多

The goats in different groups were fed with penn- isetum, purpureum Schum cv. Taiwan, [P. Purpureum. cv. Mort x （P. americanum x P. purureum） cv. Guimu No. 1] and P. purpureum cv. Southern China respectively. In the 60-days-test, the nutritional value of the forages, the intake, growth and economic benefits of the goats were determined and analyzed. The resuits showed that, the weight gain of the goats feeding with P. purpureum Schum cv. Taiwan was remarkable, with the daily weight gain reaching （144.44 ± 17.80） g, which were 32.37% and 88.48% higher than the control groups. The feed reward in P. purpureum Schum cv. Taiwan group was the highest, with feed conversion rate of 19. 10：1 and the significant economic benefits. On the whole, P. purpureum Schum cv. Taiwan with a high nutritional value and a good palatability was a kind of excellent forages for goats.展开更多
