Lablab purpureus seed as a supplement for goats fed low quality roughage
Ismartoyo, R. M. Dixon, R. F. Slocornbe, J. H. G. Holmes
Young goats were fed low quality roughage ad libitum and supplements of insect-damaged Lablab purpureus (var. Highworth) seed fed at approximately 3, 6 or 12 g/kg liveweight (LW), or sweet lupin seed (Lupinus angustifolius var. Uniharvest) fed at 12 g/kg LW. Roughage intake was not changed by 3 or 6 g/kg LW levels of Lablab or by 12 g/kg LW lupin supplement, but was reduced (p<0.05) by 35% by 12 g/kg LW Lablab supplement. Organic matter (OM) digestibility was increased by all supplements, and digestible OM intake was increased by the 6 g/kg LW Lablab and 12 g/kg LW lupin supplements. LW gain and feed conversion ratio were not changed by 3 or 6 g/kg LW Lablab or the 12 g/kg LW lupin, but were reduced (p<0.05) by 12 g/kg LW Lablab supplement. It was concluded that young goats could efficiently utilize supplements of Lablab purpureus seed fed at levels of up to 6 g/kg LW. However, when 12 g/kg of the Lablab seed was fed, poor performance suggested that the goats were adversely affected by anti-nutritional factors which were not neutralized by rumen fermentation.
