Spartina alterniflora compound feed for Chinese mitten crabs

Abstract

The invention relates to a spartina alterniflora compound feed for Chinese mitten crabs, and belongs to the technical field of compound feeds for aquatic products. The spartina alterniflora compound feed is prepared from 30-60 parts of fish meal, 140-280 parts of soybean meal, 110-220 parts of rapeseed meal, 65-130 parts of flour, 40-80 parts of peanut meal, 40-81 parts of blood cell protein powder, 10-20 parts of calcium dihydrogen phosphate, 5-10 parts of a shrimp and crab premix, 15-30 parts of fish oil, 1.25-2.5 parts of choline chloride, 15-30 parts of bentonite, 15-30 parts of stone powder, 20-40 parts of cuttlefish paste, 0.5-1 part of a spartina alterniflora feed additive, 0.1-0.25 part of an antioxidant and 0.5-1.0 part of a mildewproof agent. When the spartina alterniflora compound feed is used in the same breeding area and in the same management mode, the best water stability, the best economic benefits and the best breeding effects are achieved.

Description

technical field [0001] The invention relates to a Chinese mitten crab compound feed, which belongs to the technical field of aquatic product compound feed. Background technique [0002] Spartina alterniflora is a seaside salt marsh plant that produces sulfonate esters (sulfonate amines, sulfonate flavones, etc.) in a high-salinity environment; feed additives produced with Spartina alterniflora extracts, It has an obvious effect on improving the survival rate of freshwater crab seedlings, the weight gain rate after feeding and reducing the feed coefficient. [0003] Eriocheir sinensis is mainly fed with commercial feed in artificial breeding, and there are few research reports on the compound feed of Eriocheir sinensis. However, the existing Chinese mitten crab feed is still deficient in attracting food and nutritional balance, so the present invention has developed a selection of raw materials and their proportions, so that the prepared mitten crab feed is comprehensive in ...

[0003] Eriocheir sinensis, the artificial breeding is mainly fed with commercial feed, and there are few research reports on the compound feed of Eriocheir sinensis.

However, the existing Chinese mitten crab feed is still deficient in attracting food and nutritional balance, so the present invention has developed a selection of raw materials and their proportions, so that the prepared mitten crab feed is comprehensive in nutrition. It has unique technical characteristics in terms of balance and food attraction
