A trial population of black soldier fly larvae was raised on organic waste generated by the White Oak Pastures red meat abattoir during the summer months of 2012-2013. Two different rearing approaches were utilized and an experiment was conducted to determine the rate of biomass conversion of organic waste to mature soldier fly larvae over the course of one generation.
The production of free range organic poultry is economically and sustainably challenging for producers. The extended growing period required to raise mature, free range birds is generally twice that (12 weeks) of those raised in industrial chicken houses (6 weeks) (McMurray Hatchery, 2014) . Because birds are kept longer, all associated costs are higher per bird. Although free range poultry do receive a portion of their diet from their environment they also must be provided a supplemental feed in order to receive enough nourishment for proper development (Darre, n.d.). The cost and availability of commercial organic feed can fluctuate with market demand and is generally more expensive than industrially suited feeds. In order for organic farmers to be competitive in raising free range poultry they must find ways to lower their operating costs. By developing a lower cost, higher protein organic feed source, theoretically poultry could be raised to maturity faster, thus reducing operating expenditures. Black soldier fly larvae (Hermetia illucens, BSF) have been demonstrated to provide adequate fat and protein levels compared to traditional feed in the diets of fish, swine, and poultry, comprising 42% protein and 35% fat (Sheppard et al., 1995). Additionally, BSF make a natural, low-cost management and nutrient recycling system for manure and other sources of bio-waste (Newton et al., 2005). A recent study conducted at the Wageningen University and Research Center in Wageningen, Netherlands has indicated a strong feasibility of creating and maintaining large-scale feeding programs for swine and poultry using insect protein (Veldkamp et al., 2012).

The objective of the research is to test the effectiveness of BSF as a value adding tool in the production of supplemental organic free range poultry feed. This project seeks to further strengthen the Serengeti Model now in use at White Oak Pastures by filling a gap in the model that currently exists. Because over 60 chicken flocks (containing approximately 500 birds per flock) freely range on 80 acres there is a great need for supplemental feed. This research seeks to document how many pounds of eviscerate (X), with the help of black soldier fly (BSF) larvae, will consistently produce one hundred pounds of poultry feed (Z) in the form of BSF larvae, and how long (Y) it will take to accomplish the transformation: (X + BSF) x Y = Z (100 pounds of feed).
