Chemical Composition of Mealworm Larvae (Tenebrio molitor) Reared in Serbia
The use of insects as “novel” and natural feed materials seems to be an attractive alternative protein source for poultry, pigs and fish since more than 80% of their chemical composition (dry weight basis) is crude protein and crude fat content. Therefore, the aim of this study was to determine some...
