Sinking extruded granular feed of penaeus uannamei and preparation method thereof

Abstract

The invention discloses sinking extruded granular feed of penaeus uannamei. The density of the sinking extruded granular feed is more than 1.03, and the curing degree is 100 percent. Brown fishmeal, squid liver paste, shrimp shell meal, flour, not-genetically-modified soybean meal, canola meal, peanut meal, cassava block, mineral gunk, vitamin gunk, calcium dihydrogen phosphate, fish oil, calcium propionate, phospholipids oil and DDGS are adopted as raw materials, the feed base stock which is proportioned by weight part is regulated for 160 to 200 seconds by a double-shaft extruding full-curing bulking machine under the conditions that the steam pressure is 0.4 to 0.5MPa, the moisture is 19 to 23 percent and the temperature is 85 to 90 DEG C, and then is cured at a curing temperature of 135 DEG C, the cavity pressure of 3MPa and the curing time of 90 to 120 seconds. The sinking extruded granular feed has fewer animal raw materials and has low feed coefficient which is less than or equal to 1.1. All anti-nutrient factors in the feed are completely destroyed, the stability in the water is more than 12 hours, and the feed is completely cured.

Description

technical field

[0001] The invention relates to a feed for Penaeus vannamei, in particular to a sinking puffed granular feed for Penaeus vannamei and a preparation method thereof. Background technique

[0002] At present, ring molded pellets are commonly used in China to breed Penaeus vannamei. The amount of animal raw materials in the ring molded pellets is more than 60%, and the degree of maturity is only 30-60%. It is hard pellets combined with sinking feed, and the addition or addition of heat-sensitive ingredients before pelleting is limited, so the content of heat-sensitive ingredients is less , The feed coefficient is above 1.3. In the case of using a binder, the hard granule compound feed has a stability in water of less than 2 hours, the feed granules collapse prematurely, a large amount of nutrients are dissolved and lost, the feed utilization rate is not high, the waste is serious, and the water quality is easily polluted. During large-scale farming, feed residu...
