Embodiment 1

[0013] Weigh each raw material according to the following weight percentage: flour 20, secondary flour 20, fish meal 20, soybean meal 13, peanut meal 6, cotton meal 5, rapeseed meal 5, cuttlefish paste 5, phospholipid oil 1.5, choline chloride 0.3, sugar beet Alkali 0.25, compound multidimensional 0.15, compound mineral 2.2, immune polysaccharide 0.2, antioxidant 0.03, antifungal agent 0.05, allicin 0.02. 95% of the pulverized mixture of these raw materials passes through a 80-mesh standard sieve, and then mixes evenly with fish oil 1.3. Then, according to the method for producing special aquatic feed, it is modulated at high temperature and pressed into a ring die to form a particle size of 1.8 mm and a length of 2-2 mm. 3 times the feed pellets, then sent to a stable ripening device at a temperature of 100-105°C for 45 minutes, then dehydrated and cooled with cold wind, so that the moisture content of the pellets was about 10-11%, and the temperature of the pellets dropped to...

Embodiment 2

[0016] Each raw material was weighed according to the following weight percentages, and its preparation method was the same as in Example 1.

[0017] Flour 15, subflour 20, fish meal 15, soybean meal 17, peanut meal 9, cotton meal 9.3, rapeseed meal 5, squid paste 3, phospholipid oil 2, fish oil 1.5, choline chloride 0.35, betaine 0.35, multidimensional compound 0.2, Compound mineral 2, antioxidant 0.03, immune polysaccharide 0.2, antifungal agent 0.05, allicin 0.02.

Embodiment 3

[0019] Take each raw material by following weight percentage, its preparation method is identical with embodiment 1

[0020] Flour 27, secondary flour 16, fish meal 25, soybean meal 9, peanut meal 5, cotton meal 5, rapeseed meal 5, squid paste 2, phospholipid oil 1.5, fish oil 1, choline chloride 0.3, betaine 0.2, multidimensional compound 0.1, Compound mineral 2.6, immune polysaccharide 0.2, antioxidant 0.03, antifungal agent 0.05, allicin 0.02.

[0021] The present invention is used in Zhejiang, Jiangsu, Shanghai and other places, and can produce 50 kilograms of river crabs and 50 kilograms of green shrimps per mu, and obtains good breeding benefits.

Abstract

A composite forage for green shrimp and river crab is prepared from 18 raw materials including wheat flour, fish powder, soybean cake, fish oil, choline chloride, etc.

Description

technical field [0001] The invention relates to a feed, in particular to a formula of a compound feed for mixed cultivation of freshwater shrimp and river crab. Background technique [0002] With the improvement of people's living standards, people's demand for famous, special and high-quality aquatic products is increasing, which has driven the rapid development of aquatic product farming and made people's research on aquaculture more and more in-depth. Nowadays, the culture technology of river crab and freshwater shrimp is relatively mature, and the output has been greatly increased. People have begun to pursue higher output and newer farming models to obtain greater economic benefits. The polyculture of freshwater shrimp and river crab is an ideal nesting mode, which can improve the utilization rate of the pond, increase the yield, and reduce the bait coefficient. However, there is a lack of compound feed specially used for mixed culture of freshwater shrimp and river cr...
