Compound feed of Rana catesbeiana and preparation method thereof

Abstract

The invention discloses a compound feed of Rana catesbeiana and a preparation method of the compound feed. The compound feed comprises the following components in percentage by weight: 20%-35% of red fish meal, 3%-10 % of extruded soybeans, 20%-30% of soybean meal, 5%-10% of peanut meal, 1%-5% of beer yeast, 3%-10% of meat and bone meal, 3%-5% of rice protein powder, 19%-26% of high gluten flour, 1%-2% of sodium dihydrogen phosphate, 0.5%-2% of soybean oil, 0.5%-2% of deep sea fish oil, 0.3%-0.6% of choline chloride, 0.05%-0.3% of lysine, 0.02%-0.1% of methionine, 0.2%-0.5% of multi-vitamin and 0.5%-1% of composite mineral salt. The compound feed of Rana catesbeiana is low in price; when the compound feed is used for feeding of Rana catesbeiana, the survival rate, the weight gain rate and the feed efficiency are improved; furthermore, the ingestion of Rana catesbeiana is good, and the solution loss of the feed in water can be reduced; the feed utilization rate of Rana catesbeiana is high, and the waste of feed resources can be reduced; after the compound feed is used, Rana catesbeiana has the characteristics of rapid growth, good body sizes and less morbidity.

Description

technical field

[0001] The invention relates to the field of aquatic feed, in particular to a compound feed for bullfrogs and a preparation method thereof. Background technique

[0002] Bullfrog ( Rana catesbeiana ) belongs to Amphibians, Anura, Ranaidae, and Rana. Bullfrogs are native to the Rocky Mountains of North America. They were introduced into my country in 1959 and raised in large quantities in central and southern my country in 1986. In recent years, the bullfrog breeding industry has developed rapidly, and there are large-scale breedings in Fujian, Guangdong, Hainan and other provinces in my country. At present, the annual consumption of domestic bullfrog feed is about 150,000 tons. However, there are few research reports on the nutrition and physiology of bullfrogs at home and abroad, and the preparation of existing bullfrog compound feeds lacks relevant scientific basis.
