Abstract

An experiment was conducted to investigate the effect of supplementation with cassava leaf hay on growth rate of Co goat and F1 (Bach Thao x Co) in Luc Yen district Yen Bai province. Eight Co goats and eight F1 goats (Bach Thao x Co) of about 4-5 months of age were randomly allotted to one of two blocks. The control, goats were grazed during 4 hours per day. The treatments were levels of supplementation dried cassava leaves at 1% live weight per head per day.

Results showed that the HCN content of fresh cassava leaf was higher than the HCN content of cassava leaf hay. After 3 experimental months, DM intake, live weight of the trial goats were higher than the control goats both Co goat and F1 (Bach Thao x Co). Live weight gain and feed conversion of F1 goat (Bach Thao x Co) were improved with significant trend according to the supplementation with cassava leaf hay.

Key words: Goats, cassava leaf, supplementation, feed intake, grazing
