Abstract

Black Soldier Fly (BSF, Hermetia illucens) is an insect species that potentially can be used as a protein source for broiler nutrition. This study aimed to evaluate different inclusion level of BSF on broiler performance and blood metabolites by integrating various data from related studies using meta-analysis. Total of 12 studies that comprised of 31 data points were integrated in the database. Parameters observed included Live Weight (LW), Average Daily Gain (ADG), Daily Feed Intake (DFI), Feed Conversion Ratio (FCR), blood metabolites, and carcass proportion. The database was statistically analyzed by using mixed model method. Different studies were considered as random effects, and the level of BSF was treated as fixed effects. The model statistics used were the p-values and the Akaike information criterion. The significance of an effect was stated when its p-value was < 0.05. The results revealed that BSF feeding had significant linearly reduction effect on LW, ADG, and FCR of broiler (P < 0.05) and significant linearly increase effect on DFI and carcass proportion. However, BSF did not significantly affect on blood metabolites of broilers. It can be concluded that BSF negatively affect the performance of broiler.

Highlights

One of the determining factors for the success of the livestock industry is the availability of quality animal feed
The parameters observed in this study include live weight, average daily gain, daily feed intake, feed conversion ratio, blood metabolites, and carcass proportion
According to [17], the crude protein level of Black Soldier Fly (BSF) larvae meal is 44.9 percent, the crude fat content is 29.1 percent, the crude fiber content is 16.4 percent, and the ash content is 8.1 percent. It indicates that BSF larvae are capable of being used as an alternative feed source of insect protein. [18] concluded that BSF meal could substitute fish meal for broiler feed mixtures without affecting dry matter digestibility

Summary

Introduction

One of the determining factors for the success of the livestock industry is the availability of quality animal feed. About 50-70% of production costs are used for feed [1]. Protein source is the most expensive component compared to other nutrient sources. In some developing countries, protein source come from animal and vegetable proteins such as fish, blood, and soybean. The price of these feed ingredients is relatively high. It can burden farmers in terms of production costs. Alternative protein sources that have been researched in recent years are insects. Insects contain high unsaturated fatty acids and can be used as an alternative feed that does not compete with humans
