Vitamin premixed feed for fingerling period of Chinese idle and preparation method

Abstract

The invention relates to a grass carp fish seed period vitamin premix compound and a preparation method thereof, and belongs to the technical field of a feed additive used for the fish breeding. The vitamin premix compound is prepared by mixing vitamin A, vitamin D, vitamin E, vitamin K3, vitamin B1, vitamin B2, nicotinic acid, calcium pantothenate, vitamin B6, vitamin B12, folic acid, biotin, phaseomannite, vitamin C and bean meal powder according to a certain percentage, and added in the feed according to 0.5 percent of proportion. The vitamin premix compound solves the problems that the mixture ratio and the dosage of the existing vitamin premix compound do not fit to the grass carp, a grass carp grows slowly by using the feed to breed the grass carp in the fish seed period, and the coefficient of the feed is high, etc. The vitamin premix compound has accurate mixture ratio and reasonable material selection, meets the needs of the grass carp in the fish seed period for the vitamin, improves the special growth rate and the rate of live weight growth of the grass carp, and the survive rate of the of the grass carp parr, has low feed coefficient and low breeding and manufacturing costs, and is applicable to feed the grass carp under one year in the fish seed period.

Description

Technical field: [0001] The invention relates to a grass carp fingerling stage vitamin premix and a preparation method thereof, and belongs to the technical field of feed additives for fish breeding. Background technique [0002] Vitamins are low-molecular organic compounds necessary for grass carp to maintain normal physiological functions. Under extensive feeding conditions, grass carp can eat green feed and have low production performance, so vitamin deficiency generally does not occur. However, with the intensive feeding of grass carp becoming more and more intensive, the production performance of grass carp has been greatly improved. The stocking density of grass carp is high during the fingerling period, and it is impossible to eat a large amount of green feed. Therefore, vitamins are added to the feed to supplement the natural ingredients contained in the feed. The lack of vitamins has become the consensus of all feed manufacturers.
