Abstract

The invention discloses special granular feed for young acipenser dabryanus and a preparation method thereof. The special granular feed adopts the main materials: fish meal, soybean meal, peanut meal, yeast, L-methionine, L-phenylalanine, wheat meal, fish oil, soybean oil, multiple vitamins and multiple minerals and the like. The special granular feed is prepared by the steps of resieving, drying and granulating the materials. The special granular feed for young acipenser dabryanus disclosed by the invention has the advantages that all the used soybean meal, the peanut meal and the yeast are rich in domestic yield, the imported protein source with low price and good quality is not needed; after the foreign phytase, the L-methionine and the L-phenylalanine are added, the nutrient in the feed can meet the need for fast growth of the acipenser dabryanus; the weight gain rate, the special growth rate, the feed efficiency and the disease resistance of the young acipenser dabryanus are obviously improved; the used amount of the fish meal can be reduced, the cost of the feed can be greatly reduced, the utilization rate of the fish to the feed can be improved and the nitrogen emission and pollution to a water body are reduced.

Description

[0001] The invention relates to a preparation method of a feed, in particular to a preparation method of a special granular feed for juvenile Dabry's sturgeon. Background technique [0002] Dabry's sturgeon, belonging to the order Sturgeoniformes, belongs to the family Acipenseridae, and is also known as the Yangtze River sturgeon. It is a unique and rare fish in the Yangtze River system in China. However, in recent years, due to environmental pollution, overfishing and construction of water conservancy projects along the river, its habitat has been destroyed, and its resources have been declining. It has now been listed as a national first-class protected animal. In order to better protect this rare species and increase its resources, in recent years, relevant scientific research, public institutions and hydropower development companies along the Yangtze River have carried out large-scale artificial breeding and release activities. [0003] At present, the artificial breeding...
