Bloat
Lablab has been occasionally reported to cause bloat in cattle when fed green as the sole feed (ILRI, 2013; Hamilton et al., 1968), but reports have been infrequent and the risk of bloat is considered to be low (Mullen, 1999).
Antinutritional factors
Lablab seeds contain antinutritional factors including tannins, phytate and trypsin inhibitors. Processing methods, such as removing the seed coat, soaking and cooking, are effective in alleviating the effects of these factors (Lambourne et al., 1985; Deka et al., 1990).
Lablab leaves are free of tannins, making them a good feed for monogastric animals (Schaaffhausen, 1963 cited by Murphy et al., 1999).
