Fish meal-free crucian breeding expanded compound feed and preparation method thereof

Abstract

The invention relates to fish meal-free crucian breeding expanded compound feed and a preparation method of the fish meal-free crucian breeding expanded compound feed. The feed disclosed by the invention comprises the following components in part by weight: 4 to 8 parts of blood cell protein powder, 6 to 10 parts of corn protein powder, 3 to 5 parts of fermented soybean meal, 20 to 32 parts of soybean meal, 20 to 35 parts of rapeseed meal, 3 to 6 parts of wheat, 12 to 20 parts of flour, 4 to 8 parts of rice bran, 4 to 5.5 parts of vegetable oil, 2.0 to 3.5 parts of calcium dihydrogen phosphate, 0.2 to 0.5 part of 98.5 percent lysine hydrochloride, 0.1 to 0.3 part of 99 percent DL-methionine, 0.3 to 0.8 part of vitamin premix, and 0.5 to 1.5 parts of mineral substance premix. Through the preparation method, the blood cell protein powder and the corn protein powder are used, meanwhile, partial grease, lysine and methionine are supplemented, the vitamins and mineral trace elements are balanced, fish meal in crucian feed is completely removed, and the fish meal-free crucian breeding expanded compound feed is developed, so that feed cost is greatly reduced, and breeding benefit is increased.

Description

technical field [0001] The invention relates to a crucian carp feed and a preparation method thereof. More specifically, the invention relates to a fishmeal-free crucian carp breeding puffed compound feed and a preparation method thereof, belonging to the technical field of fish puffed feed production. Background technique [0002] Crucian carp is one of the main breeds of freshwater fish in my country. It is widely favored by consumers because of its fresh and tender meat and rich nutrition. Ranking fifth, it plays a very important role in increasing farmers' income. [0003] The cultured crucian carp in East my country is relatively concentrated, and the market consumption habit is better for large-scale crucian carp. The market size is more than 0.6 catties / tail in summer and more than 0.9 catties / tail in winter. The earlier the market is, the higher the price per catties is. The nutritional level of the feed is high. Usually the amount of fishmeal in the growing feed is ...

AI Technical Summary

Problems solved by technology

[0007] The present invention aims to solve the problems in the prior art that the feed for crucian carp breeding requires a large amount of fish meal, resulting in high cost, or feed without fish meal leads to poor breeding effect, and provides a kind of puffed compound feed for growing crucian carp without fish meal. Through reasonable matching, the formula is completely Does not contain fish meal, which greatly reduces the formula cost, but has no significant impact on the weight gain, feed utilization efficiency and disease resistance of crucian carp. The economic benefits of breeding are significantly improved, which is conducive to increasing the income of farmers
