Problems solved by technology

[0004] In view of the phenomenon of liver function decline caused by frequent whitening of liver lesions during the breeding cycle of California sea bass, taking conventional antibiotics orally can only prevent secondary infection problems that may occur due to liver function decline, but cannot fundamentally solve the problem; while oral administration of vitamins , The effect of liver protection products of varying quality on the market in repairing liver function is not satisfactory. Exploring safe and effective technical solutions has very important promotion and application value

experiment example 1

[0059] The repairing effect of Experimental Example 1 on the whitening of the liver

[0060] A breeding base in Nanhai District, Foshan, Guangdong Province selected 12 California perch breeding ponds as a pilot, and randomly divided them into four groups A, B, C and D. Each group had three parallel ponds, and each parallel group was fed with 8,000 California perch. The mode of feeding, the daily feeding is divided into two meals in the morning and evening, wherein the three ponds of group A are fed with the functional feed prepared in embodiment 1, the three ponds of group B are fed with the functional feed prepared in embodiment 2, and the three ponds of group C are fed with the functional feed prepared in embodiment 2. Three ponds were fed with pure chilled bait, and three ponds in group D were fed with a commercially available brand of common California perch extruded feed, and the test period was 20 weeks.

[0061] During the test period, liver tissue slices were randomly ...

Abstract

The invention relates to a functional feed, in particular to the functional feed for preventing and treating a white liver lesion of micropterus salmoides, and a preparation method thereof. The feed comprises, by weight percentage, 15-25% of fish meal, 20-35% of chicken powder, 16-22% of soybean meal, 8-15% of flour, 4-8% of squid extractum, 1-2% of calcium dihydrogen phosphate, 1-2% of a multi-vitamin premix, 1-2% of a multi-mineral premix, 2-4% of fish oil, 1-2% of soybean oil, 1-2% of phosphatide oil, 2-7% of corn protein powder, 0.2-0.5% of pennisetum sinese herb extract, 0.1-0.5% of mulberry leaf fermentation liquid, and 0.1-0.3% of red rooted saliva root fermentation liquid. Compared with a common puffed feed for the micropterus salmoides, a feed formula provided by the invention can meet the basic nutrient demands of juvenile fishes, medium fishes and adult fishes of the micropterus salmoides, also can effectively enhance exchangeable backflow between artery blood and vein blood in hepatic tissue blood circulation, and has a good prevention effect and a repair treatment effect on the white liver lesion and hepatic tissue hypofunction caused by the white liver lesion.

Description

technical field [0001] The invention relates to a functional feed, in particular to a functional feed for preventing and treating California perch liver whitish lesions and a preparation method thereof. Background technique [0002] California perch, also known as largemouth bass (Micopterus salmoides), belongs to Perciformes, Sunfish family, and Perch genus taxonomically, and is a typical carnivorous freshwater fish. During the breeding cycle, the liver health of California sea bass is closely related to the health of the fish. Practice has proved that when California perch has liver lesions or continuous physiological stress stimulation, the symptoms are often manifested as the apparent color of the liver becoming white, and the adverse effects are mainly reflected in the high feed coefficient, low fatness, physical decline, and disease. Indicators such as high rate and death rate are evident. [0003] In general, the graying of the liver of California sea bass is mainly...
