Expanded pellet feed for trionyx sinensis and preparation method thereof

Abstract

The invention discloses an expanded pellet feed for the trionyx sinensis. The curing degree of the expanded pellet feed is 100 percent. The expanded pellet feed is prepared from domestic white fish meal, America white fish meal, imported eel-grade red fish meat, flour, cassava pieces, soy beans, non-transgenic soybean meal, fermented soybean meal, pregelatinization starch, milk powders, mineral premix, vitamin premix, monocalcium phosphate, calcium propionate and phosphatide oil by using a twin-screw extruding fully-curing expansion machine to firstly carry out quenching and tempering on the materials for 160 to 200 seconds under the conditions that a vapour pressure is between 0.4 and 0.5MPa, a humidity is between 19 and 23 percent, and a temperature is between 85 and 90 DEG C, and then carry out curing on obtained product under the conditions that a curing temperature is 180 DEG C, a cavity pressure is between 22 and 28atm and a curing time is between 25 and 30 seconds. Each kilogram of mineral premix comprises Mg, Na, K, Fe, Cu, Mn, Zn, Se, Co and I. The expanded pellet feed for the trionyx sinensis has the advantages of reasonable configuration of various elements required by nutrition and growth, complete curing, resistance to cause damage to all nutritional factors, low cost, higher stability in water and higher digestibility.

Description

technical field

[0001] The invention relates to soft-shelled soft-shelled turtle feed, in particular to an extruded granular feed for soft-shelled soft-shelled turtle and a preparation method thereof. Background technique

[0002] Chinese soft-shelled turtle (turtle) has higher requirements for protein and fat, and needs more animal protein sources. The global fishmeal production has declined and the price has risen rapidly, making the cost of soft-shelled turtle breeding higher and higher. Conventional soft-shelled turtle feed is a compound powder, as the announcement number is CN100534319, and the announcement date is September 2, 2009. The title is a patent for invention of a pollution-free soft-shelled turtle compound feed, which discloses fish meal comprising 50% to 70%. , 15% to 30% starch, and an appropriate amount of yeast powder, milk powder, egg yolk powder, gluten powder, natural stone powder or trace elements composed of calcium dihydrogen phosphate, compound vit...
