We are experimenting with black soldier fly (BSF) larvae as an effective duck feed alternative.

THE PROBLEM

Duck breeders in Klungkung and Tabanan, Bali, face difficulties finding alternative sources of feed for their ducks. Their current duck feed consists of a mix made up of three parts bran with one part concentrate and is viewed as problematic for two primary reasons:

  • Large-scale duck breeders in Bali cannot produce their own bran and concentrate. Instead, they must purchase this feed from non-Bali based suppliers, leaving the breeders vulnerable to inconsistent sourcing, excessive shipping fees, and price fluctuations when there is a supply disruption.
  • The bran and concentrate is expensive impacting their duck farming profit. The concentrate costs approximately IDR 385,000 (~US$28.89) per 50 kg sack (or about IDR 7,600 or ~US$0.57 per kg), while bran costs IDR4,000 (~US$0.3) per kg. On average, each duck breeder in Klungkung has 3,000 ducks bred for their meat and eggs. This amount of ducks require 100 kg of concentrate and 300 kg of bran per day, which totals nearly IDR 2,000,000.00 (~US$150) in daily feeding costs.

To address these challenges, there is a need to improve the supply of duck feed in Bali by introducing a more sustainable, locally produced, and inexpensive product. 

THE SOLUTION

BSF larvae are a harmless species of insect that is common to tropical and warmer temperate regions. Rearing BSF is an efficient way to dispose of organic waste as the BSF larvae who feed on the organic waste are converted into a protein and fat-rich biomass suitable as a feed supplement.

We want to test whether BSF larvae is an effective duck feed alternative by comparing three types of duck feed:

  1. Mix of concentrate and bran (current feed);
  2. Mix of bran and BSF larvae; and
  3. Mix of vegetable waste and BSF larvae.

Our partner, the Black Soldier Fly Farm Bali will rear the BSF and feed the ducks for 40 days, the standard time needed for meat ducks to grow to maturity and be ready for sale. We will isolate 10 ducks for each group, feeding them exclusively on one type of duck feed. Made Kusuma, from the Black Soldier Fly Farm Bali will measure these indicators in each group after 40 days:

  • the weight of each duck;
  • the costs for each of the three varieties of feed; and
  • the selling price for each duck once they reach maturity.

THE EXPECTED IMPACT

We hope the result of the test indicates that BSF is a viable alternative source of duck feed. If the BSF larvae prove nutritionally comparable to the current feed, duck breeders in Bali can save money by purchasing feed that is produced locally and is not as prone to price fluctuation.
