Low-fish meal compound feed for macrobrachium rosenbergii and preparation method thereof

Abstract

The invention discloses a low-fish meal compound feed for macrobrachium rosenbergii and a preparation method thereof, wherein the compound feed is characterized by consisting of the following components in parts by weight: 15 to 20 parts of fish meal, 10 to 30 parts of soybean meal, 8 to 12 parts of chicken meal, 6 to 10 parts of corn gluten meal, 5 to 15 parts of fermented soybean meal, 5 to 15 parts of peanut meal, 3 to 5 parts of cerevisiae fermentum, 3 to 5 parts of shrimp shell powder, 3 to 5 parts of squid liver powder, 1.5 to 2 parts of fish oil, 1 to 2 parts of bean oil, 1.5 to 2 parts of soybean lecithin, 10 to 25 parts of flour, 0.2 to 0.5 parts of vitamin mixture and 0.5 to 1 part of mineral mixture; the preparation method comprises the steps of: mixing the above components; modifying quality of the mixture under certain steam pressure, humidity and temperature; curing the quality-modified mixture under certain temperature and pressure, and finally extruding the mixture to the feed with the particle diameter ranging from 1 to 4mm. The feed has the advantages of small using amount of the fish meal, low feed cost and simultaneously enhancing the digestibility of macrobrachium rosenbergii.

Description

technical field [0001] The invention relates to an aquaculture feed, in particular to a macrobrachium rosenbergii low-fishmeal compound feed and a preparation method thereof. Background technique [0002] Macrobrachium rosenbergii is fresh and tender, delicious, rich in protein, has high economic value, and is popular among the public as aquatic products, so its artificial breeding is very extensive. During the breeding process of Macrobrachium rosenbergii, in addition to providing a good growth environment , Carrying out scientific management also needs to choose suitable feed, most of the existing macrobrachium rosenbergii compound feeds include fishmeal, but in recent years, due to the depletion of global marine fishery resources, the world's fishmeal production has declined, and the price has soared. From the end of 2009 to 2010, the world's fishmeal The price has risen by more than 60%, which is the most serious challenge to the development of my country's fish feed indus...

[0002] Macrobrachium rosenbergii is fresh and tender, delicious, rich in protein, has high economic value, and is popular among the public as aquatic products, so its artificial breeding is very extensive. During the breeding process of Macrobrachium rosenbergii, in addition to providing a good growth environment , Carrying out scientific management also needs to choose suitable feed, most of the existing macrobrachium rosenbergii compound feeds include fishmeal, but in recent years, due to the depletion of global marine fishery resources, the world's fishmeal production has declined, and the price has soared. From the end of 2009 to 2010, the world's fishmeal The price has risen by more than 60%, which is the most serious challenge to the development of my country's fish feed industry. At present, the amount of fishmeal in the compound feed used in the cultivation of Macrobrachium rosenbergii in my country is between 25-35%, and the feed cost accounts for 60% of the breeding cost. above
