Palm meal fish feed capable of improving flavor of fish and preparing method thereof

Abstract

The invention discloses a palm meal fish feed capable of improving the flavor of fish and a preparing method thereof. The feed is prepared from, by weight, 170-180 parts of palm meal, 58-74 parts of corn meal, 32-35 parts of clam worm meal, 23-26 parts of mulberry residue, 3-4 parts of table salt, 5-6 parts of yali vinegar, 25-28 parts of peanut leaf, 20-23 parts of sargassum, 14-16 parts of tenebrio molitor meal, 18-21 parts of rye bran, 0.2-0.3 part of black pepper powder, 24-27 parts of shrimp meal, 17-18 parts of soybean curb residue, 3-4 parts of chicken bruillon, 3-4 parts of duck liver, 4-5 parts of kidney bean, 2-3 parts of crowndaisy chrysanthemum, 0.5-0.8 part of perilla oil, 0.1-0.2 part of EM zymophyte, 1-2 parts of fructus aurantii powder, 3-5 parts of trehalose and 2-3 parts of sesame paste. By the adoption of the feed, the flavor, quality and palatability of fish can be improved, fish can better absorb and utilize nutrients and grow and gain weight more easily, the feed intake of fish is increased, feed digestibility is improved, and feed consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a palm meal fish feed with improved fish flavor and a preparation method thereof. Background technique [0002] Palm meal is also known as "oil palm kernel dregs" or "palm kernel dregs". It is the residue of palm kernel oil removed when pressing palm kernels. It is initially in the shape of black mud and processed after removing impurities and controlling moisture. Small brown particles. Palm meal contains 14-17% crude protein, 8-10% crude fat, and 15-20% crude fiber. It is rich in phosphorus, manganese, iron and other elements, and is rich in vitamins B and E. In the current situation of rising food prices, palm meal is valued by people because of its low price, high protein content, and its non-toxic and harmless to animals. Replacing part of the grain with palm meal can effectively alleviate the food crisis and save the input cost of breeding, thereby significantly impro...

Problems solved by technology

Although there are many advantages in using palm meal instead of corn and other grains, it is difficult to digest due to its poor palatability, which is not conducive to the absorption and utilization of nutrients.

Although the traditional fermentation technology can improve this shortcoming of palm meal, the improvement is not obvious, mainly because the processing level is not high, and the macromolecular nutrients cannot be completely decomposed, so the palatability has not been greatly improved. improvement

In addition, traditional fish feed also has disadvantages such as weak disease resistance and weak growth and development regulation, which cannot achieve rapid improvement in fish farming benefits
