Premix feed for female minks in reproduction period and preparation method

Abstract

The invention discloses a premix feed for improving the growth speed of female minks in the reproduction period and the nutritional substance digestion rate. The premix feed is prepared from the following raw material components in kilogram: whey powder, vitamin, vitamin B5, vitamin B6, vitamin B9, vitamin B12, biotin, compound enzyme preparations, vitamin A, vitamin C, vitamin E, vitamin D, vitamin K, methionine, lysine, arginine, threonine, choline chloride, ferrous sulfate, copper sulfate pentahydrate, manganese sulfate, zinc sulphate monohydrate, sodium selenite, cobalt chloride, potassium iodate, yeast chromium, dihydropyridine, probiotics, calcium hydrogen phosphate, edible salt and bean cake powder. The premix feed can effectively improve the breeding performance of the female minks, increase the nutritional substance digestion rate of the female minks in the reproduction period, reduce the mobility of intestinal diseases of the female minks, and increase the breeding benefit.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a premixed feed for improving reproductive performance and feed utilization rate of female mink and a preparation method thereof. Background technique [0002] Mink is a precious fur animal, and mink is known as the "King of Fur". my country's mink breeding industry started relatively late, but its development speed is relatively fast, with more than 60 million mink in stock. In the process of mink breeding, reproduction is the most important part of breeding production. The reproductive performance of female mink directly determines the economic benefits of mink breeding. With the development of the breeding industry, the mink breeding industry is gradually developing in the direction of scale and standardization. However, the high rate of mink empty pregnancy and miscarriage, and the low litter rate and survival rate of offspring have always been a bottleneck in my co...

Problems solved by technology

However, there are problems with the premixed feed for female minks currently on the market: the use of the premixed feed is confusing, and some of the premixed feeds are directly replaced by pigs or poultry, resulting in low reproductive performance of the mink and some nutritional and metabolic diseases. Too high will cause mink poisoning, reduce reproductive performance, and cause waste of resources. The added amount of some nutrients is too low, which cannot meet the nutritional needs of female mink reproduction and growth and development of young mink; in order to reduce mink intestinal diseases, a large number of antibiotics are used. It is not conducive to the reproduction of female minks and the development of young minks, and at the same time causes environmental pollution; some premixed feeds can ensure that some nutrients meet the needs, but they cannot improve the digestion and absorption of nutrients such as protein, fat, and carbohydrates in full-price feeds, resulting in insufficient feed nutrients. And affect the reproductive performance; part of the premixed feed contains hormone products, due to the use of unreasonable dosage, the mink reproductive failure

The unreasonable combination of nutritional components and incomplete nutritional components in the premixed feed directly affect the reproductive performance and economic benefits of mink breeding
