Abstract
The invention relates to a puffing feed for California perch. The puffing feed is prepared from the following raw materials in percentage by weight: 10-16% of gluten powder, 5-8% of yeast powder, 4-8% of superior shrimp powder, 25-35% of imported fish meal, 18% of national superior degreased fish meal, 5% of chicken meat powder, 12% of soybean meal, 3% of fish oil, 1.5% of liquid phosphatide, 1.5% of calcium dihydrogen phosphate and 3% of a self-made California perch special premix, wherein the percentage is the mass percentage of the components of the puffing compound feed accounting for the total quantity of the puffing compound feed. The nutritive indexes of the puffing feed for California perch disclosed by the invention can reach that the moisture content is smaller than or equal to 12.5%, the crude protein is larger than or equal to 46.0%, the crude fat is larger than or equal to 5.0%, the crude fibers are smaller than or equal to 18.0%, the calcium is 1.0-4.0%, the total phosphorus is larger than or equal to 1.0%, the sodium chloride is 0.3-4.0%, and the lysine is larger than or equal to 2.6%; all the nutritional requirements of the California perch are met, the characteristics of the limit of the California perch for carbohydrate metabolism and liver metabolism functions are explored, the prepared feed with the formula can be fed to the California perch in the whole course until the California perch appears on the market, fish like to eat the feed so that the fish can grow quickly, the somatotype of the fish is uniform, the dorsal meat is thick, the internal organs such as the livers are healthy, and the mouth feel of the fish meat is better than that of fish fed with iced fresh.
Description
technical field [0001] The invention relates to the field of aquatic animal feed, in particular to an extruded California perch feed. Background technique [0002] California perch, also known as largemouth bass, is a ferocious freshwater carnivorous fish that basically grows wild in rivers and lakes. Because of its delicious meat and extremely scarce quantity, it is expensive and can only be seen at high-end banquets. In the past two or three years, artificial breeding has been explored. However, because the bait fed is basically fresh fish, the incidence of disease is extremely high, and fishery resources are wasted. Prone to outbreaks of hepatopancreatic lesions and growth stagnation. In the existing market, 95% of farmers are directly feeding chilled fish to raise California perch, which is seriously polluted and labor-intensive. [0003] The existing California perch feed preparation technology has not fully grasped the nutritional needs of California perch. About 5% o...
