Compound feed for rhynchocypris lagowskii

Abstract

The invention discloses compound feed for rhynchocypris lagowskii, and belongs to the technical field of freshwater fish culture feed. The compound feed is composed of, by mass, 10.4%-15.2% of fish meal, 31.7%-36% of bean pulp, 7.4%-10.6% of rapeseed dregs, 7.2%-9.6% of cottonseed meal, 6.4%-7.5% of corn, 7.2%-11.5% of wheat, 9.4%-13.8% of feeding yeast, 3.0%-4.5% of rice bran, 2.2%-3% of vegetable oil, 1.5% of mineral substance additives and 0.5% of complex vitamins. The vegetable oil is soybean oil or corn oil or peanut oil. The compound feed is especially suitable for the digestive physiology characteristics of rhynchocypris lagowskii, and is good in palatability and high in utilization rate, growing speed is high, the culture effect is good, and high economic benefits are achieved.

Description

Technical field [0001] The invention belongs to the technical field of freshwater fish breeding feed, and particularly relates to the compounding of a labradorite feed. Background technique [0002] Phoxinuslagowskii Dybowskii belongs to Cypriniformes, Cypriniformes, Cyprinidae, Leuciscinae, Phoxinus Agassiz, and Phoxinus Agassiz. Mainly distributed in waters such as Heilongjiang, Tumen River, Liaohe River, Yalu River, and the tributaries of the upper and middle reaches of the Yellow River. Its living water temperature is 0 degrees to 26 degrees, and the optimum water temperature range for growth is 15 degrees to 24 degrees. It requires fresh water quality and dissolved oxygen at 5.0mg / L above. [0003] Lazy anchovy is a wild small economic fish. The common individual in natural waters is 30g-40g, and the largest artificially cultivated individual can reach more than 500g. Its meat is tender and delicious, with few intermuscular spines and extremely rich nutrition. After determi...

AI Technical Summary

Problems solved by technology

[0005] To sum up, the development of artificial breeding of Lassweeper has a bright prospect, but currently there is no special feed for Lassweeper with good palatability, balanced nutrition, high efficiency and environmental protection, and high conversion rate in the freshwater aquaculture fish feed market. Special feeds for carp and crucian carp are used in production. Although they can be eaten, different types of fish have different requirements for nutrients. Unsuitable nutrition directly leads to low feed efficiency, slow growth and body color in the breeding process. Undesirable consequences such as abnormality and low immunity not only increase the cost of breeding, but also destroy the water environment for breeding. Nutrition and feed problems have become the bottleneck factors that limit the development of large-scale and intensive farming of Lasbyi
