เปรียบเทียบการเจริญเติบโตของหนอนแมลงวันดำ Hermetia illucens (Linn.) (Diptera: Stratiomyidae) ที่เลี้ยงด้วยเศษวัสดุเหลือทิ้งทางการเกษตร เพื่อใช้เป็นแหล่งโปรตีนในสูตรอาหารไก่ไข่

Abstract

Black soldier fly Hermetia illucens (Linn.) (Diptera: Stratiomyidae) is not both transmitted-disease insects and insect pest. Their larvae feed on dead plant matter and animal carcasses which then decompose these organic materials. Recently, black soldier fly larvae were mass reared for used as animal feed. Study on black soldier fly larvae reared on agricultural byproducts commonly found at Southern Thailand aims to investigate on the suitability of different formula diets from agricultural byproducts for mass rearing of black soldier fly larvae and the suitability of black soldier fly larvae used as protein source replaced in soybean meal of laying hen diet. Seven diet formulas were investigated as 1) palm cake 2) palm cake + banana 3) bran 4) bran + banana 5) bran + palm cake 6) bran + palm cake + coconut pulp and 7) bran + palm cake + coconut pulp + banana. Results present that the most suitable diet formula for black soldier fly larvae rearing with highest total larval weight and largest larval size was bran + palm cake + coconut pulp + banana. Moreover, black soldier fly larvae had shortest larval stage and longest pupal stage when reared on this diet formula. Result of the study on effect of dried powder of black soldier fly larvae used as protein source replaced in soybean meal on potential of egg production and quality of 51-58 weeks old Hy-Line Brown laying hen present that there was not significant difference in the egg production among three laying hen groups fed on different diet formula 1) 50% of soybean meal replaced with dried powder of black soldier fly larvae 2) 100% of soybean meal replaced with dried powder of black soldier fly larvae and 3) 100% soybean meal (control). Laying hen fed on diet with 100% of soybean meal replaced with dried powder of black soldier fly larvae consumed the least amount of food and had significant lower feed conversion ratio than that other group. Result show that quality of egg of laying hen fed on diet mixed with dried powder of black soldier fly larvae was not differed from egg of laying hen fed on common diet with significant darker color of egg yolk.
