Expanded feed for promoting weight reduction of grass carp as well as preparation method thereof

Abstract

The invention belongs to the field of grass carp feeds and discloses an expanded feed for promoting weight reduction of grass carp as well as a preparation method thereof. The expanded feed consists of the following components in percentage by mass: 4 to 10 percent of flour, 4 to 10 percent of corns, 5 to 15 percent of cassava, 8 to 15 percent of rice bran, 5 to 12 percent of soybeans, 10 to 15 percent of bean pulp, 20 to 25 percent of rapeseed meal, 6 to 12 percent of cottonseed meal, 3 to 6 percent of Baijiu vinasse, 2 to 5 percent of fish meal, 2 to 5 percent of meat meal, 1.5 to 2.5 percent of soybean oil, 1 to 2 percent of a zeolite powder, 2 to 3 percent of monocalcium phosphate and 2 percent of premix. Through multi-validation, the grass carp achieves a good weight-reducing effect,the growth is not influenced, the internal organs such as liver are healthy, and transportation resistance is achieved. Through reasonable matching of the soybean, the bean pulp, the rapeseed pulp, the fish meal, the meat meal and the like, the protein content and the fat content of the feed are moderate, and the fatness of the grass carp eating the feed is 1.9 to 2.3 percent.

Description

technical field [0001] The invention belongs to the field of grass carp feed, in particular to an extruded feed for promoting weight loss of grass carp and a preparation method thereof. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: In recent years, the competition for grass carp feed has become increasingly fierce. In order to pursue the growth rate of grass carp, some feed companies have made the nutritional index (especially crude fat) of grass carp feed higher, but grass carp has become obese and even "hanging belly". , "Show appearance" is not good, which brings great difficulties to the sales of grass carp. Fat metabolism is blocked, and excessive fat is deposited in the hepatopancreas and mesentery, etc., resulting in a large proportion of grass carp viscera, and grass carp becomes obese and even "hanging belly". In terms of physical indicators, "hanging belly" is mainly manifested as the fish body f...
