Inclusión de harina de calamar gigante Dosidicus gigas como fuente de proteína en dietas para gallinas ponedoras.

The giant squid Dosidicus gigas has a great potential to elaborate human consumption products and balanced food due to its high protein content. The objective of this work was to include 10 and 20 % of giant squid meal (GSM) as a protein source in diets for laying hens. One hundred thirty-five Bovans White hens were distributed as follows: control (T), 10 % (T1), and 20 % (T2), in a 6-week trial. The Productive variables measured were the physical quality of the egg, crude protein, amino acid profile, and sensory evaluation (taste), Raw GSM protein (77.76 %), amino acids (g aa/100 protein): methionine + cysteine (3.76), lysine (10.16), isoleucine (4.26), leucine (6.56), phenylalanine (4.56) and tryptophan (2.0). The Productive variables measured were (P < 0.05) in posture (%); egg weight (g); food conversion (kg: kg) and egg mass (bird/day/g), and without difference (P > 0.05) consumption (bird/day/g); Physical quality of the egg with differences (P < 0.05) in egg weight (g), albumin height (mm) and Haugh units (UH). In egg raw protein and amino acid differences (P < 0.05), Sensory evaluation (P > 0.05), rating the 3 treatments in 4 "likes". According to the results, it is concluded that giant squid flour not exceeding 10 % can be an alternative as a source of protein for feeding posture hens. [ABSTRACT FROM AUTHOR]
