Abstract 

Twenty four weaned goats (Bach Thao*local) with initial weights of 9.7±0.32 kg and ages ranging between 3 to 4 months were used in an experiment to evaluate the use of fresh sweet potato vines (SPV) and Sesbania grandiflora foliage (SG) given as sole diets or as mixtures. Sesbania foliage was gradually replaced with fresh sweet potato vines at four levels: 0% (SPV0), 50% (SPV50), 75% (SPV75) and 100% (SPV100), based on DM content of the feeds.

The same amount of DM was offered to all treatment groups, but intake decreased linearly as Sesbania foliage was replaced by sweet potato vines. When given as the sole feed to growing goats, the foliage of Sesbania grandiflora was superior to fresh sweet potato vines, in terms of feed intake and live weight gain, the latter being 50% greater on Sesbania  (64 g/day versus 44 g/day). Replacement of Sebania with 50% fresh sweet potato vines on a dry matter basis resulted in acceptable live weight gains (60.6 g/day).

Farmer experience indicates that the constraint to the widespread use of Sesbania grandiflora  for feeding goats is the relatively low yield and slow rate of re-growth after pruning.
