Evaluation of the inclusion of domestic fly larva (Musca domestica L.) as an alternative in the feeding of Gallus domesticus, in the municipality of Soracá, Boyacá. Bol. Cient. Mus. Hist. Nat. Univ. Caldas [online]. 2023, vol.27, n.2, pp.87-95.  Epub 18-Abr-2024. ISSN 0123-3068.  https://doi.org/10.17151/bccm.2023.27.2.5.

The objective of this study was to evaluate the effect of inclusion of common fly larvae (Musca domestica L.) in the diet of Cobb line broilers, on the productive parameters, carcass quality and the economic viability. A total of 100 one-day old Cobb broiler chicken were used, distributed in a completely randomized design with 4 treatments and 5 repetitions of 5 birds in each experimental unit, for a period of 42 days. The treatments consisted of replacing the commercial concentrate with different levels of larvae meal (HDL), as follows: T1: 100% concentrate; T2: 88% concentrate and 12% HDL; T3: 83% concentrate and 17% HDL and T4: 78% concentrate and 22% HDL. The productive variables evaluated were: final weight, weight gain and feed conversion. The quality variables were: carcass weight, carcass yield, breast and leg yield. The results obtained for productive parameters in the birds did not show differences (P> 0.05), the carcass quality indicators showed differences in the performance of the ham leg, with treatment 1 being the one that obtained the best results (P <0.05). The best breast development was obtained in T4 (34.21% of the of carcass weight). It was concluded that the inclusion of domestic fly larvae meal generates a development similar to chickens fed with conventional feed. On the other hand, the use of this meal in diets for broilers reduces production costs by 40%, being a good feeding strategy in poultry farms.
