为了研究断食对泥鳅体长、体重等影响,泥鳅断食7 d1、4 d、21 d、28 d后,进行复食28 d。结果表明,与非断食组泥鳅比较,断食7d后泥鳅体重下降,复食7 d后即恢复正常;断食14 d2、1 d和28 d后的泥鳅体重明显下降,复食7 d后均恢复至断食前生长水平。泥鳅断食28 d内在复食7 d后体重恢复正常,可为养殖户节省饲料,增加收入。
In order to study the effects of fasting on the body length and body weight of loach, the loach was fasted for 28 days after being sacrificed for 7 days and 4 days, 21 days and 28 days, respectively. The results showed that compared with the non-fed group, the weight of loach decreased after 7 days of fasting, and returned to normal after 7 days of re-feeding. The weight of loach decreased significantly on the 14th and the 2nd, Pre-fasted growth level. After 28 days of re-feeding, the weight of loach returned to normal after 7 days of rehydration, which could save feed for farmers and increase income.
