밀기울 혼합 농업부산물을 첨가한 갈색거저리 유충 먹이원 급여가 이들 농업부산물의 영양성분에 미치는 영향

Abstract

This study aimed to investigate the effects of feeding Tenebrio molitor (TM) larvae with wheat bran mixed agricultural by-products on the nutritional composition of these agricultural by-products or their potential as substitutes for livestock protein feed. The treatments were randomly divided into two groups with three replicates in each group in the current study (G1: a mixture of 100 g wheat bran and 100 g soy pulp + 50 g of 4th instar TM larvae; G2: a mixture of 100 g wheat bran and 100 g mugwort by-product + 50 g of 4th instar TM larvae). The trial lasted 15 d. The two groups significantly affected these agricultural by-products' pH, crude protein, and dry matter content (p<0.05), but not the ash content. In addition, the two groups fed to TM larvae had a significant effect (p<0.05) on ADF contents, and there was no significant difference in NDF content between the treatments (p>0.05). In conclusion, although a wheat bran and soy pulp mixture was considered suitable as feed for TM larvae by lowing ADF and NDF contents, it did not bring the expected results; the crude protein content was low.
