Resumen
FUENTE-MARTINEZ, Benjamín et al. Preliminary studies of metabolizable energy and apparent ileal amino acid digestibility of jumbo squid (Dosidicus gigas) meal in chicken diets. Abanico vet [online]. 2023, vol.13, e2022-8. Epub 09-Jun-2023. ISSN 2448-6132. https://doi.org/10.21929/abavet2023.1.
The objective was to determine apparent metabolizable energy (AMEn) and apparent ileal digestibility (AID) of amino acids in giant squid (Dosidicus gigas) (GSM) meal, as a protein alternative in diets for broilers. Experiment 1: in GSM the AMEn and the AID of its amino acids were determined. Ninety-six chickens were fed a diet with 8 and 16% GSM for 21 days of age. Experiment 2: 72 chickens were fed with 16 and 20% GSM in the diet for 42 days. Productive parameters, carcass yield, skin color and flavor meat were evaluated. Results: AMEn was 3376.15 kcal/kg and AID of amino acids greater than 68%, except histidine (21%) and cysteine (47%). Weight gain and final weight were reduced with 16% GSM (P < 0.05) compared to the control at 21 days of age, however at 42 days no differences were detected (P > 0.05) between treatments with 16 and 20%, both in the productive parameters and in carcass yield and chicken weight (P > 0.05). The taste of the meat was not affected by GSM (P > 0.05). It is concluded that GSM is an alternate source of protein in diets for broilers.
