Problems solved by technology

However, in the process of long-term feeding of high-grade feed to ensure that the channel catfish has a good growth advantage, the physical weakening of the channel catfish is also serious. The main symptoms are loss of appetite, dull body color, and white or yellow liver. "Mottled", enlarged gallbladder, pale yellow bile, etc.; when the temperature difference changes or the water quality is unstable, the susceptibility of channel catfish to pathogenic bacteria increases, and sporadic diseases often occur. In s...

[0035] Breeding experiment

[0036] (1) Materials and methods

[0037] 1.1 Materials

[0038] 1.1.1 The channel catfish used in the experiment was purchased from a channel catfish breeding farm in Meishan, Sichuan.

[0039] 1.1.2 Aeromonas hydrophila was preserved and provided by Haida Animal Husbandry and Aquaculture Research Center.

[0040] 1.1.3 The test feeds were selected from the feeds prepared in Examples 1 and 2 of the present invention, and the blank feed was the basic feed without adding the natural plant compound and the multi-grain compound of the present invention.

[0041] 1.2 Method

[0042] 1.2.1 Experimental grouping and feeding management

[0043] Select healthy channel catfish (100±5g) of uniform size and set up 3 treatments (Example 1, Example 2, control group), and set 3 replicates for each treatment. For each repetition group, 100 channel catfish were used to temporarily raise them in an open-air cement pond, and they were fed with basic feed until ...

Abstract

The invention discloses a channel catfish immunity enhancing feed, which comprises the following components in parts by weight: 5-14 parts of meat and bone meal, 15-25 parts of rapeseed meal, 20-40 parts of de-hulled soybean meal, 0.2-0.5 part of choline chloride, 15-22 parts of wheat middling, 0.5-1 part of soybean oil, 0.2 part of vitamin premix, 0.15 part of mineral premix, 1-2 parts of calcium dihydrogen phosphate, 0.01-0.03 part of plant enzyme, 0.05-0.1 part of cholate substances, 0.03-0.06 part of a toxin adsorbent, 0.1-0.3 part of a natural plant compound and 0.1-0.3 part of a polysaccharide compound. According to the immunity enhancing feed disclosed by the invention, nonspecific immunity of the channel catfish is enhanced through various compounds, and through reasonable proportioning of various natural plants and the polysaccharide components, nonspecific immunity of the channel catfish is significantly improved and infection resistance of the fish is enhanced; and meanwhile, growth performance of the fish is improved and a food coefficient is reduced.

Description

technical field [0001] The invention relates to the field of feed, in particular to an immune-enhancing feed for channel catfish. Background technique [0002] Channel catfish (Ictalurus Punctatus) belongs to Siluriformes (Siluriformes) and Ictaluridae (Ictaluridae). The meat is tender, without intermuscular spines, rich in protein and vitamins, and delicious in taste. It is a high-quality fish that is popular among farmers, processors and consumers. my country has promoted breeding in more than 20 provinces and cities since the success of artificial breeding in 1987. [0003] In the intensive breeding mode of channel catfish, high stocking density is the basis for obtaining high breeding returns. Feeding high-grade feed can promote the growth of channel catfish, shorten the breeding cycle, and achieve early market launch. However, in the process of long-term feeding of high-grade feed to ensure that the channel catfish has a good growth advantage, the physical weakeni...
