The main marketed parts of squid are the mantle, the head with tentacles, and fins. However, when the whole squid does not meet quality standards for human consumption it can be used for broiler feed. The objective of the study was to include giant squid (Dosidicus gigas) meal (GSM) in broiler rations to increase the content of the n-3 fatty acids eicosapentaenoic (EPA), docosapentaenoic (DPA), and docosahexaenoic (DHA) in chicken meat. Two hundred Ross 380 chickens, half male, half female, and one day old, were randomly distributed in a 4x2x2 factorial arrangement. The factors were the treatment (0%, 1.67%, 3.34%, and 5.01% of GSM in the diet), sex, and content of n-3 in the legs with thighs and the breasts. Each treatment had five repetitions with 10 birds each. There were no differences (p > 0.05) in the production parameters for both sexes. The contents of EPA, DPA, and DHA increased in the females and in the legs with thighs (p < 0.05) with GSM. Acceptance for the flavor and texture of meat was higher in the treatment with 1.67% GSM than in the other treatments. It is concluded that GSM is an alternative for increasing the amount of n-3 in chicken meat.
鱿鱼主要的上市销售部位是胴体、带触手的头部和鳍。然而，当整只鱿鱼不符合人类食用的质量标准时，它可用于肉鸡饲料。本研究的目的是在肉鸡日粮中添加巨型鱿鱼（茎柔鱼）粉（GSM），以提高鸡肉中n-3脂肪酸二十碳五烯酸（EPA）、二十二碳五烯酸（DPA）和二十二碳六烯酸（DHA）的含量。200只1日龄的罗斯380肉鸡，雌雄各半，按照4×2×2析因设计随机分组。因素包括处理方式（日粮中GSM含量分别为0%、1.67%、3.34%和5.01%）、性别以及大腿和胸部腿部的n-3含量。每个处理有5个重复，每个重复10只鸡。两性的生产性能参数没有差异（p>0.05）。添加GSM后，雌性以及大腿和胸部腿部的EPA、DPA和DHA含量增加（p<0.05）。GSM含量为1.67%的处理组对肉的风味和质地的接受度高于其他处理组。得出的结论是，GSM是增加鸡肉中n-3含量的一种选择。
