Effects of SCFA& MCFA and Lactobacillus on Growth and Immunity of macrobrachium nipponensis.

macrobrachium nipponensis

Original text of the document:

This experiment was conducted to investigate the effects of SCFA& MCFA and Lactobacillus on the growth and immune performance of macrobrachium nipponense.

In this study, 6 treatment groups were set up, G0 group was the blank control group, G1~G5 groups were Lactobacillus group, 0.15% GML group, 0.15% glyceryl butyrate group, and 0.15% GML group + 0.15% glyceryl butyrate group, 0.2% GML + 0.2% glyceryl butyrate group. All treatment groups (G1~G5 groups) need to be mixed with Lactobacillus bacteria solution by spraying at a ratio of 1:4 (bacteria solution/mL:feed/g) when feeding.

In this study, the growth indicators of macrobrachium nipponense, the expression of various immune response factors and the activity of immune-related biological enzymes were measured.

The results show:

1. Compared with the control group, the growth and weight gain rates of the G1 and G4 groups were increased by 24.99% and 26.69% respectively (P<0.05), and the specific growth rates of the test groups G1, G4 and G5 were respectively increased by 18.92%, 18.92% and 14.41% compared with the control group (P <0.05).

2. In terms of serum immunity, the content of malondialdehyde (MDA) in G1 and G3 groups increased by 60.71% and 47.61% respectively compared with the control group (P<0.05); the content of catalase (CAT) in G2, G4, G5 Compared with the control group, the control group increased by 219.22%, 140.94%, and 431.68% respectively (P<0.05).

3. In terms of total superoxide dismutase (T-SOD) activity, the G2, G3, and G5 groups increased by 50.92%, 62.77%, and 115.36%, respectively, compared with the control group. The immune-related glutathione peroxidase (GSH-Px) activity in the hepatopancreas was increased by 50.37%, 56.09%, and 50.66% in the G1, G3, and G5 groups compared with the control group, respectively (P<0.05);

4. The expression of immune-related response genes Myd88, HSP60 and HSP70 also increased in different degrees in each test group compared with the control group.


The combination of a certain concentration of medium and short-chain fatty acid glycerides and Lactobacillus can significantly improve the growth and immune performance of macrobrachium nipponensis.
