Samples were degutted or not degutted. The worms were further subjected to either cooking for 1h (remaining in boiling water for 45min), hot ash roasted for 5-7min or not treated (control). Treatment had an effect on the level of most minerals, on the in vitro true dry matter digestibility (IVTDMD) (P0.05). Degutting had an effect on CP, fiber components, minerals, (P0.05) affected by degutting. There were no interactions (P>0.05) between treatment and degutting for ash CP, CP"a"v", ADF, ADL, ADIN, P, Zn, Mn or Mg. An interaction was observed for NDF (P<0.01), Ca (P<0.001) and IVTDMD (P<0.05). A significant and negative correlation was observed between ADF and IVTDMD (r=-0.86, P<0.001). CP and IVTDMD were positively correlated (r=0.88, P<0.001). Therefore, it will not be necessary to degut Mophane worms destined for livestock feeding. High fibre levels in the undegutted Mophane worms would make it necessary to degut worms which are destined for human consumption. Given the scarcity of protein in Botswana it is important to evaluate locally available feed resources as potential livestock feeds.
