生物饲料对凡纳滨对虾生长、免疫及消化功能的影响
Effects of Bio-feed on the growth,immune performance and digestive properties ofLitopenaeus vannamei
摘要
Abstract
The effects of bio-feed on growth, immune resistance and digestive performance of shrimp (Litopenaeus vannamei) were studied during an 8-week experiment. The bio-feed was composed of peptides obtained from enzyme hydroly-sis, vegetableprotein obtained from effective microbefermentation and cell wall-broken yeast protein. The immune enzyme activities of haemolymphand digestive performance in hepatopancreas were detected, and the growth per-formance and environmental conditions were compared. The results showed that the average production in treat-ment groups was 1242.5 kg/ha, higher than 1180.5 kg/ha in control group; and the survival rate in treatment group was 91.5%, 5.3% higher than that in control group. The feed coefficient of bio-feed is 0.96, whereas that of standard feed is 1.01. After 15~30 days treatment, the activities of SOD and LZM and the haemolymph protein content were all higher than those in control group, while the anti-bacterial activity had no significant difference between these two groups. Challenged with Vibrio parahaemolyticus (1.03×107 CFU/mL, 200 μL/shrimp), the survival rate of shrimp in treatment group was higher than that in control group within 24 h. In addition, the total proteaseactivity significantly increased in treatment group. The levels of NH4-N and NO2-N were lower in treatment group, but there were no significant differences.关键词
