preparation example Construction

[0020] Preparation of tissue extract: Accurately weigh the tissue, add physiological saline at a ratio of 1:9 to homogenate the tissue, centrifuge at 3000rpm for 10 minutes, and obtain the supernatant as 10% tissue extract.

[0021] Determination of SOD enzyme activity: hydroxylamine method, determined by Nanjing Jiancheng kit.

[0022] Determination of CAT enzyme activity: Visible light spectrophotometry, determined by Nanjing Jiancheng kit.

[0023] Judging criteria for stage V: the ovaries are dark green, filling 3 / 4 of the carapace, and obvious eggs can be seen with the naked eye.

[0024] Calculation formula:

[0025] Relative weight gain rate = (final average body weight - initial average body weight) / initial average body weight × 100.

Abstract

The invention relates to a feed additive capable of improving the antioxidant function and reproductive performance of macrobrachium nipponensis. The feed additive is prepared from, by weight, 15-27 parts of radix isatidis, 17-25 parts of astragalus polysaccharides, 4-8 parts of flos lonicerae, 4-8 parts of fructus rosae laevigatae, 4-13 parts of radix et rhizoma rhei, 8-15 parts of rhizoma calami, 7-15 parts of shrimp shell meal, 4-9 parts of shell powder and 16-22 parts of yolk immunoglobulin. The feed additive has the advantages that 2-8% of the feed additive is stirred in basic feed of which the protein content is 37.4%, when the water temperature rises to 10 DEG C in March, feeding is started, feeding is carried out twice each day, continuous feeding is carried out for 1 month, thereby being capable of not only improving the growth speed of macrobrachium nipponensis and the antioxidant function of the hepatopancreas, but also promoting the development of the ovary of female shrimps; the problems that a macrobrachium nipponensis female parent is slow in growth speed, low in disease resistance and slow in ovary development in the traditional macrobrachium nipponensis breeding process are solved, the additive amount is low, and the preparation method is simple.

Description

technical field [0001] The invention relates to a feed additive for aquatic animals, in particular to a Macrobrachium japonicus compound feed additive, and belongs to the technical field of feed additives. Background technique [0002] Macrobrachium nipponense (Macrobrachium nipponense), commonly known as freshwater shrimp, also known as river prawn, belongs to the subclass of soft armor, decapod order, parade suborder, long arm shrimp family, and macrobrachium genus. Japanese river prawns are tender and nutritious, and are favored by consumers. There are large-scale breeding in Jiangsu, Anhui, Shanghai, Zhejiang, Fujian, Jiangxi, Guangdong, Hunan, Hubei, Sichuan, Hebei, Henan, Shandong and other places in China. Among them, Jiangsu Province has the largest scale of Macrobrachium prawn farming. [0003] In the traditional culture process of Macrobrachium japonicus, with the increase of the culture density of Macrobrachium japonicus and the deterioration of the culture envi...
