Abstract

The present invention discloses an trachinotus ovatus with a formula feed by adding a squid paste to improve the feeding rate,including the following weight percentage of raw materials:27% - 28.5% of fish meal , 19.5% - 20% of soy protein concentrate, 8% - 9% of soybean meal, 6% of peanut meal, 22.2% - 23.6% of secondary powder, 7.8% - 7.9 % of fish oil, 2% of calcium dihydrogen phosphate, 1% of vitamin premix, 1% of mineral premix, 0.5% of choline chloride, 0.5% of lecithin, 1.5% - 3% of squid paste. The technical proposal of the invention improves the feeding rate of the trachinotus ovatus in the low fishmeal condition and the palatability of the feed by adding the squid paste to the common trachinotus ovatus feed;It is proved that the oval pomfret can be used to improve the feeding rate of oval pomfret and promote the growth of oval pomfret and improve the utilization rate of feed, At the same time to improve the oval pomfret disease resistance and antioxidant capacity, effectively reduce farming costs, improve farming income. It is proved that the trachinotus ovatus with a formula feed by adding a squid paste to reduce the fishmeal content of its formula, effectively improve the feeding rate of oval pomfret, promote the growth of oval pomfret, improve feed utilization, meanwhile, it can improve disease resistance of the trachinotus ovatus and antioxidant capacity, effectively reduce farming costs, improve farming income.

Description

Technical field [0001] The invention relates to a fish feed, in particular to a compound feed for oval pomfret for improving the feeding rate by adding squid paste. Background technique [0002] Fishmeal is the most important source of protein for aquatic feed. However, due to the depletion of fishery resources, the world's total fishmeal output has been declining year by year, the price of fishmeal has been rising, and the cost of aquaculture has continued to increase, which has severely restricted the development of aquaculture. Using vegetable protein sources to replace fish meal has become one of the important ways to save fish meal. However, according to aquaculture practice, the utilization of plant protein in feed by marine fish is not ideal. The reason is that the replacement of fish meal by plant protein sources reduces the quality of food in feed, while anti-nutritional factors and flavor substances increase and decrease. The palatability of the feed affects the appeti...
