A kind of premixed feed for growing mink and its preparation method

Abstract

The invention discloses premixed feed for improving the growth speed and the nutrient substance digestion rate of minks at a breeding period. The premixed feed per one kilogram comprises the following raw material components: 265g-300g of corn protein powder, 15g-20g of compound vitamin B, 25g-35g of a complex enzyme preparation, 250000-300000 IU of vitamin A, 12g-15g of vitamin C, 2000-2500 IU of vitamin E, 50000-80000 IU of vitamin D, 0.6g-1g of vitamin K, 25g-28g of methionine, 15g-18g of lysine, 0.5g-1g of biotin, 55g-70g of choline chloride, 7g-9g of ferrous sulfate monohydrate, 9g-12g of copper sulfate pentahydrate, 10g-12.5g of manganese sulfate, 16g-20g of zinc sulphate monohydrate, 5g-6g of sodium selenite, 6g-8g of cobalt chloride, 5g-6g of potassium iodate, 10g-15g of yeast, 0.5g-0.6g of pantothenic acid, 3g-5g of nicotinamide, 0.5g-0.6g of folic acid, 140g-150g of calcium hydrogen phosphate, 30g-40g of table salt and 260g-300g of puffed corn powder. The premixed feed can be used for effectively improving the daily gain and the digestion rate of proteins, fat and carbohydrates of the minks at a breeding period, reducing the diarrhea rate of the minks and improving the culture benefits of the minks.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a premixed feed and a preparation method for improving the growth rate and feed utilization rate of mink in the breeding period. Background technique [0002] Mink is a small precious fur animal with extremely high economic value. Its guard hairs are straight, flat and shiny, full and dense underpile, strong in warmth retention, flexible, strong and light in skin, diverse and beautiful in coat colors, and so on. It is known as the "King of Fur". my country is a big mink breeding country. With the continuous increase of mink breeding, the shortage of feed resources and the rising cost of feed, the problems in mink feed are becoming more and more obvious. In order to save feed costs, some farmers and feed manufacturers choose to increase animal feed or plant protein feed with low nutrient digestibility, so that the nutrients such as protein, fat, vitamins, trace elements ...

AI Technical Summary

Problems solved by technology

.The problems existing in the premixed feed currently on the market are: the addition of some nutrients is too low or the proportion is not appropriate to meet the rapid growth and development needs of minks, and some nutrients are too high to directly cause waste of resources, and even cause chronic disease in minks. Poisoning inhibits their growth and development. In order to reduce the incidence of intestinal diseases in minks, a large number of antibiotics are used, which is not conducive to the growth and development of animals, and at the same time causes environmental pollution.

The unreasonable combination and incomplete nutrition of the premixed feed directly affect the growth and development of mink and the economic benefits of breeding
