| Description | There is an increasing demand for protein rich materials in the animal feed industry in South Africa. Intensive cattle husbandry as well as abattoirs are producing large quantities of organic waste, the protein content of which is not utilized. The compost worm, Eisenia fetida, can be reared in large numbers on this waste. This opens up the possibility to recover waste protein if E. fetida could be used as a protein source in animal feeds. The value of the protein was therefore researched by determining the general chemical composition and amino acid composition. The earthworm meal contained all the essential amino acids required in poultry feeds, in favourable ratios. The methionine and lysine availability was higher than that of fish meal. Daar bestaan ’n toenemende behoefte aan proteïenryke grondstowwe vir die veevoerbedryf in Suid-Afrika. Die intensiewe veebedryf en abattoirs produseer jaarliks groot hoeveelhede organiese afvalmateriaal waarvan die proteïeninhoud nie benut word nie. Die komposwurm, Eisenia fetida, kan op groot skaal op die afval geteel word. Dit is dus potensieel moontlik om dierlike afvalproteïene te herwin indien E. fetida as proteïenbron in gebalanseerde veerantsoene aangewend kan word. Daarom is die proteïenwaarde van die erdwurmspesie ondersoek deur die algemene chemiese samestelling en aminosuursamestelling te bepaal. Erdwurmmeel bevat al tien essensiële aminosure vir pluimvee, in besonder gunstige verhoudings. Daarbenewens is die listen- en metionienbeskikbaarheid van erdwurmmeel hoër as die van vismeel. | |
