Problems solved by technology

[0003] At present, there are also farmers who "stock up" to avoid the peak of a large number of Chinese mitten crabs on the market in October, but do not pay attention to the development of the gonads to make the cream plump, or still follow the gen

Embodiment Construction

[0008] The present invention adopts phospholipid, fish oil, vegetable oil and livestock animal oil as raw materials, and mixes the phospholipid, fish oil, vegetable oil and livestock animal oil in a weight ratio of 2:1:1:1 to form the nutritional additive. Among the above-mentioned raw materials, the preferred vegetable oil is soybean oil, and the livestock animal oil is lard. The prepared mitten crab fattening feed nutritional additives were sealed and stored at a low temperature of 4°C.

[0009] In the process of feed processing, spray plating can be used to directly add >8% feed weight nutritional additives and 0.5% vitamin E to the feed; if the nutritional additives are manually added to the pellet feed, the added amount is 4-4% of the feed weight. 6% (because the fat content of current river crab routine feed formula is 6-8%).

[0010] The proportion of raw materials in the fattening feed is 10% of imported fish meal, 16% of soybean meal, 17% of rapeseed meal, 15% of cot...

Abstract

A feed nutritive additive for fattening eriocheir sinensis relates to an aquaculture feed additive. The additive solves the problem that provisioning food cannot meet the needs of eriocheir sinensis parental gonadal development so a feed nutritive additive for fattening is needed to guarantee that the hepatopancreas of the eriocheir sinensis can gain rich nutrition and that the eriocheir sinensis can have good gonadal development as well as have plentiful cream and fat. The technical proposal of the invention which takes phospholipid, fish oil, vegetable oil and livestock animal oil as raw materials is characterized in that the phospholipid, the fish oil, the vegetable oil and the livestock animal oil are mixed well on weight percentage of 2:1:1:1 into the nutritive additive. The invention is used as feed nutritive additive for fattening the eriocheir sinensis.

Description

Technical field: [0001] The present invention relates to an aquaculture feed additive. Background technique [0002] A key problem currently existing in the cultivation of Chinese mitten crabs in my country is that the fattening work of Chinese mitten crabs is neglected in production, resulting in uneven quality of marketed crabs, insufficient plumpness of marketed adult crabs, and insufficient fat and fat, which affects the quality of marketed crabs. quality and efficiency. The meaning of Chinese mitten crab fattening is to strengthen the cultivation of adult crabs (usually called green crabs) that have last reproduced and moulted for about one month (usually from late September to early November) to obtain cream Fat and plump, delicious and pollution-free food crab. Whether the ointment is full or not is manifested in the nutrition of the hepatopancreas (lipid storage) and the fullness of the gonads (ointment). The most direct indicator is whether the gonads are well deve...
