Compound feed for improving body color of rana nigromaculata and preparation of compound feed

Abstract

The invention relates to feed and in particular relates to compound feed for improving the body color of rana nigromaculata. The compound feed is prepared from the following raw materials according tothe ratio: 40 to 42.5 percent of soybean meal, 10 to 11 percent of imported fish meal, 8 to 9 percent of meat and bone meal, 5 to 6.5 percent of rapeseed meal, 2 to 3 percent of peanut meal, 22 to 23percent of flour, 3 to 3.5 percent of oil, 2 to 2.5 percent of a phagostimulant, 0.2 to 0.4 percent of lutein, 0.5 to 0.6 percent of multivitamin and 2.5 to 2.6 percent of multi-minerals. The compound feed provided by the invention has the advantages that the compound feed for improving the body color of the rana nigromaculata contains the raw materials which have balanced nutrient ratios, are reasonable in toxin control and are scientific in pigment matching; a condition that heads and backs of the rana nigromaculata become blue, caused by the fact that the rana nigromaculata is lack of pigments so that pigment synthesis is hindered, is easy to improve.

Description

technical field [0001] The invention relates to a feed, in particular to a compound feed for improving the body color of the black-spotted frog. Background technique [0002] The black-spotted frog is also called "black-spotted sidefold frog". The general body length is about 7-10 cm, and the weight of adult frogs is generally 50-100 grams. The female frog is larger and the male frog is slightly smaller. The head is slightly triangular in shape, slightly longer than wide. The eyes are large and protruding, and there is a round tympanic membrane behind the eyes, which is large and obvious. [0003] Since its development in 2012, the artificial breeding of black-spotted frogs has achieved full feed feeding. The breeding area has gradually expanded from a few provinces such as Sichuan and Hunan to Hubei, Jiangxi, Anhui, Zhejiang, Guangdong, Jiangsu, and Chongqing. Among them, in Hubei (mainly distributed in Qianjiang, Xiantao, Jianli) and Hunan (mainly in Yiyang, Yueyang), th...

Problems solved by technology

With the expansion of the scale of black-spotted frog breeding, a series of problems have also appeared in the breeding: unreasonable nutrients in the feed, unscientific ratio of protein, vitamins and pigments, excessive toxins in raw materials, etc., which lead to black-spotted frogs appearing in the growth stage. and back blue phenomenon, affecting the sales of black-spotted frogs
