Problems solved by technology

Existing carp feed is mainly based on feed with protein content as high as 36%. When carp is fed with this feed, the utilization rate of effective protein in the feed is low by carp, and undigested nitrogenous substances are released from the excretion of the fish body. , will increase the content of nitrite and ammonia nitrogen in the water body and cause pollution to the aquaculture water body. Feeding the above-mentioned feed for a long time will deteriorate the water quality environment

Abstract

The invention relates to a low-protein carp feed. The feed comprises wheat-middlings, wheat bran, rapeseed cake, soya bean meal, corn germ meal, alfalfa meal, spouting corn bran, fish meal, meat and bone meal, sesame seed meal, monocalcium phosphate, bentonite, soybean oil, lysine, methionine, choline chloride and a premix and is characterized in that: alternanthera philoxeroides, parthemum powder, garlic powder, pine needle meal and rhubarb powder are added into the feed. A processing method for the low-protein carp feed comprises the following steps of: smashing and / or grinding various components in the feed; adding various raw materials into a stirring machine for stirring; and packaging the stirred feed. The feed can enhance the immunity and disease resistance of low-protein carp, effectively lower the morbidities of enteritis, gill breaking, red skin disease and explosive bleeding disease of the low-protein carp, increase fry survival rate, promote growth and effectively lower the bait coefficient of the low-protein carp.

Description

technical field [0001] The invention relates to a feed, in particular to a low-protein carp feed and a processing method. Background technique [0002] Carp is one of the main freshwater aquaculture species in my country. It is famous for its delicious meat and rapid growth. It has a large aquaculture area in my country. Carp are mainly fed with artificial compound bait, and the feed cost accounts for more than 70% of the entire breeding cost. Existing carp feed is mainly based on feed with protein content as high as 36%. When carp is fed with this feed, the utilization rate of effective protein in the feed is low by carp, and undigested nitrogenous substances are released from the excretion of the fish body. , will increase the content of nitrite and ammonia nitrogen in the water body and cause pollution to the aquaculture water body, and feeding the above-mentioned feed for a long time will deteriorate the water quality environment. Therefore, it is necessary to improve ...
