Mineral premix feed for frequently breeding female meat rabbits and preparation method of feed

Abstract

The invention relates to a mineral premix feed for frequently breeding female meat rabbits and a preparation method of the feed. According to the formula, the feed comprises the following components in parts by weight: 1-2 parts of copper glycinate, 10-18 parts of iron glycinate, 4-8 parts of manganese citrate, 22-28 parts of zinc lysine, 3.5-4.5 parts of selenium yeast, 0.1-0.2 part of ethanediamine dihydroiodide, 0.1-0.2 part of cobalt carbonate, 20 parts of magnesium sulfate heptahydrate, and 28.8 parts of bentonite. The mineral premix feed is produced by adopting the multi-compartment weighting burdening technology, and the variation coefficient of the finished mineral premix feed is less than 5%. The mineral premix feed has the characteristics of being complete in mineral substance nutrients, balanced in matching, high in digestion rate, less in usage amount, and environmentally friendly, high-efficiency and safe. By adopting the premix feed, the estrus rate, gravidity rate and consecutive laying property of the frequently bred female rabbits can be increased, the lactation yield and the quality of milk can be improved, the survival rate and the weight of weaning litter can be increased, the utilization efficiency of the female rabbits on the mineral elements can be enhanced and the like. By adopting the formula, the frequently bred female rabbits can give birth to more than seven young rabbits annually, and about 50 commercial rabbits can be provided annually.

Description

technical field [0001] The invention belongs to the technical field of animal feeding, and relates to an environment-friendly mineral premixed feed for frequent breeding meat rabbits and female rabbits and a preparation method thereof. [0002] Background technique [0003] Meat rabbit breeding has a long history and a broad mass base in my country. It has the characteristics of "small investment, food saving, high efficiency and quick results". It has become one of the important ways for farmers in poverty-stricken areas to get rid of poverty and increase economic income. According to the data of the Food and Agriculture Organization of the United Nations (FAO), China’s rabbit meat production was 705,000 tons in 2012, accounting for about 40% of the world’s rabbit meat production in the same period. my country has become the world’s largest producer of rabbit meat; according to the national rabbit industry technical system survey, In 2012, my country's breeding female rabbi...

AI Technical Summary

Problems solved by technology

Manganese-deficient female rabbits have no obvious estrus, and even if they conceive, their conception rate is 35-40% lower than normal rabbits; selenium deficiency can lead to abnormal estrus or even no estrus in female rabbits, and the conception rate is low, which affects the normal development of the fetus in the mother ; Magnesium deficiency leads to prolongation of gestation period of female rabbits, and severe magnesium deficiency will reduce the litter size; Cobalt deficiency will affect the reproductive performance of female rabbits and significantly reduce the conception rate

[0005]The existing mineral premixes for female rabbits in China can meet the needs of single breeding of female rabbits in terms of apparent quantity supply, but because the source of mineral elements is mainly It is an inorganic mineral element with low digestibility and cannot fully and effectively meet the nutritional needs of female rabbits for single breeding. For intensive frequent breeding female rabbits (more than 7 litters a year), there is still a gap in the supply of nutritional needs. It is so large that it has led to the low conceiving rate, poor continuous production, live litter size, light litter weight, low milk production, poor nutritional quality of milk and poor body condition of female rabbits in the current production of female rabbits in China. The current situation, the direct result is that the survival rate of the young rabbits is low, and the female rabbits have fewer births per year (5 to 6 births).
