Embodiment Construction

[0007] According to the special metabolic characteristics of cobia, the present invention creatively develops the "cobia liver strengthening agent", forming a new technology to support the sustainable and efficient development of cobia feed industry and aquaculture industry.

[0008] Weigh 25kg of vitamin C-polyphosphate, 15kg of L-carnitine; 15kg of lecithin, 15kg of sulfuric acid, 13kg of rhubarb, 12kg of hawthorn, and 5kg of Polygonum multiflorum. These raw materials are pre-crushed and passed through a 120-mesh sieve, and then mixed evenly to obtain the cobia liver-enhancing agent.

[0009] Experiments in Guangdong and Hainan from 2005 to 2006 showed that the liver-enhancing agent was used in the whole cycle of cobia inshore cage culture, and the feed coefficient of cobia decreased by 15.1% and 15.3%, respectively, and the survival rate increased by 21.3% and 19.5% compared with the control group. %(Table 1).

Abstract

Cobia hepatinica is prepared from the following components by weight: 20 to 30 percent of vitamin C-polyphosphonate, 10 to 20 percent of L-Carnitine, 10 to 20 percent of lecithin, 10 to 15 percent of sulfuric acid, 10 to 15 percent of rhubarb, 10 to 15 percent of hawthorn, and 5 to 10 percent of radix-polygoni multiflori. The invention has the advantages that the cobia hepatinica can be used as a feed additive in cobia feed and is added into the cobia feed by only 0.1 to 0.2 percent, can prevent the liver fat infiltration of cobia, reinforce the function of the liver, improve feed efficiency, boost the growth of the cobia and improve the survival rate of the cobia, has no any adverse effect to the palatability of feed, and has stable resources of raw materials used in the cobia hepatinica, low cost and simple production technology.

Description

technical field [0001] The invention relates to a feed additive, in particular to a liver-enhancing agent for cobia. technical background [0002] Fatty liver problem is a fairly common problem in the artificial culture of marine fish. Diseased fish show loss of appetite, slow growth, low feed remuneration, and severe death. Although there are sporadic reports on the basic research on the pathogenesis of fatty liver at home and abroad, the research is not systematic. Although there are also some additives or drugs for preventing and treating fatty liver in the domestic market, the effect is not good, and the outstanding performance is that the effect is unstable, and the improvement of disease resistance and survival rate is not obvious. [0003] Cobia (Rachycentron canadum) is an important seawater economic fish that is cultivated on a large scale in southern my country. Due to the fast growth rate of the fish (the seedlings in that year can grow to 3-4kg) and strong met...
