China Animal Husbandry Street Library can also buy a copy of Practical Fur Animal Breeding Technology. The special breeding market is complex, and the terminal fur price is difficult to predict. China's fur industry has experienced severe winters of 1.988 and 1.998. Will 2008 be accompanied by the warm winter law of 10? In today's uncertain fur market and falling fur prices, we are enjoying special breeding. First, the causes of rising feed costs and future trends. In recent years, the soaring prices of grain and oil, aquatic products and livestock and poultry products have led to an increasing proportion of feed costs in the total cost of fur animal breeding. According to statistics, the feed cost in August 2007 increased by 20% ~ 30% compared with the same period of last year. Coupled with the uncertainty of fur prices in 2007 and the rising wages of aquaculture workers, it can be said that special aquaculture is facing a difficult and overwhelmed state. At the same time, the warm winter in 2006 and more diseases led to poor breeding effect of fur animals, which undoubtedly made fur animal breeding worse in 2007. As we all know, the depletion of marine fish resources and fresh water resources in recent 10 years has caused the price of fish for fur animals to rise continuously. Therefore, the cost of mink feed based on fish will not be reduced. The low prices of chickens and pigs in 2005 and the first half of 2006 led to the shortage of meat in 2006 and 2007, and the prices of livestock and poultry products remained high. By-products of livestock and poultry, such as chicken racks and minced meat, also exist the phenomenon that people and animals compete for resources. With the further expansion of ethanol production from corn, the prices of grain and food will soar. Although the demand for corn by minks and foxes is not great, the prices of livestock and poultry products such as chicken and duck racks are still very dependent on food. Facing the unprecedented development of China's animal husbandry, we no longer have illusions about the decline of raw materials. Fortunately, the fur user market has been formed; Fur processing enterprises have gone out of the stage of exploring how to use fur, and the next step is to focus on what quality and price fur to use. For breeding, how to produce marketable fur is the main task at present Second, how to raise it reasonably when the market is not good; How to maximize the profit between the input cost of breeding and the selling price of raw hides is recognized by the fur industry. The key to getting good skin lies in two aspects: reproduction and feeding. Only by relying on advanced breeding management can we give full play to the excellent characters of excellent breeding animals. Avoiding breeding risks is mainly to improve the survival rate of litters, improve fur quality and reduce breeding costs. Especially for new farmers, the risk of breeding technology is higher than that of market fluctuation. 1, scientific introduction, breeding, seed selection and seed retention; Improving fertility science introduction, breeding, seed selection and seed retention have become the top priority. As Professor Liu Zhiping said, he is willing to make great efforts to cultivate his fine varieties for a long time and establish a core group of moderate scale. Select the groups with good fur quality, high fecundity and good body shape from the existing groups of foxes and raccoons, and directionally cultivate their own superior varieties; Or introduce improved varieties from developed fur countries at the same latitude, domesticate or improve them locally, and cultivate new varieties adapted to the local climate and environment. For example, only by introducing excellent raccoon breeds from Finland to improve the low-quality raccoons in China can we improve and stabilize the overall price of raccoons in China and enhance international competitiveness. Compared with foreign countries, the reproduction rate and survival rate of foxes and minks in China are relatively low. For example, the average survival rate of mink in Denmark is 4.5-5.5, the empty pregnancy rate is below 5%, and the breeding rate of blue fox is 7-8. Therefore, scientific breeding and improving the survival rate of reproduction have become the key to improve economic benefits in China. 2. Fur animal husbandry should be developed in northern high latitudes, and the advantages of cold resources in China should be fully utilized to develop fur animal husbandry. In order to improve fur quality, it is suggested to develop fur animal industry in northern China as far as possible. There are poetic climatic conditions and light cycle in the north, and the cool temperature in summer can reduce heat stress, increase food intake and increase growth rate. The cold climate in winter relatively reduces the incidence of infectious diseases and bacterial diseases, and improves the quality of fur. Otherwise, it will lead to losses due to high temperature in winter, sparse fur of fur animals, poor fur quality and inability to sell at high prices. Many farms have realized this, made full use of the north to vigorously develop fur animal industry, provided preferential policies to attract investment opportunities, and gradually moved the main battlefield of breeding to the northeast. 3. Adjust the breeding varieties, improve the comprehensive anti-risk ability, and establish the market concept. Every year, we should adjust the variety structure in this field and optimize the good varieties. Conditional and capable farmers should adhere to the "one variety-oriented, multi-variety coexistence model" to cope with the unpredictable market. For example, after mink leftovers are cooked with corn flour, 4% premix can be added to feed foxes and raccoons. Economic laws require us to do what we can. According to our local climate, geography, cultural conditions and our own economic and technological strength, it is imperative to pay attention to properly retaining and expanding the population and improving the quality of the population when the market declines. 4. Pay attention to feed quality and improve fur quality. According to the current market situation, few people are interested in raising animals so far. By the end of the year, most foxes will be skinned. Change the current situation that only foxes are paid attention to and fur animals are ignored; However, most manufacturers ignore the feeding and management of winter wool in the growing period. Due to the insufficient supply of sulfur-containing amino acids in feed, plush will grow slowly, irregularly, sparsely, burnt and have poor luster, resulting in poor fur quality, which is not comparable to the price of imported fur from Finland. Finland's feed preparation is to produce feed with corresponding protein content and energy according to the physiological needs of various animals in different biological periods and the needs of producing excellent leather, and to formulate an effective nutrition ratio scheme. For example, when feeding lactating foxes, protein accounts for 37%, fat accounts for 45%, and carbohydrate accounts for 18%. The produced feed has high dry matter content and is sticky. It is not difficult to see that provenance quality and feed quality complement each other. If we don't engage in professional feed processing, we will still treat feed in the traditional way. Even if Finnish foxes are introduced, they can't produce skins as big as Finland. Due to the short history of fox industry in China, unreasonable feed allocation or improper feeding habits lead to skin aging. There are many reasons for these phenomena, but feed factors account for a large part. At present, although there are puffed compound feed, concentrated feed, concentrate and premix in the domestic fox industry, the scope of use is small, and most of them are made by manufacturers, so it is difficult to balance various nutrients. Domestic foxes have some problems, such as high energy-protein ratio, low dry matter and fat content in diet, and unbalanced calcium-phosphorus ratio. A large number of studies show that low-protein and low-energy diet has bad effects on fox fur quality, such as the decline of fur grade, hollow fur, lack of native sheep down and so on. There are also many farmers at present. Considering the uncertain market situation, in order to save costs or lack liquidity, low-standard feeding can not meet the nutritional level required for fox production, and even the offspring of crossbreeding with excellent Finnish foxes can not show heterosis. In my opinion, even if the price of fur falls, there will still be a proper profit in the price of middle and high-grade leather. At the same time, remind the majority of breeding friends to pay attention to the quality changes of feed raw materials. With the depletion of water resources and the aggravation of environmental pollution, the fish we feed fur animals are getting smaller and smaller, and the nutritional index is no longer marked in books; With the aggravation of environmental pollution, the content of harmful substances such as heavy metals in raw materials increases year by year; At the beginning of 2007, several rains and snows caused corn mildew, and the mycotoxin content seriously exceeded the standard. After testing corn and corn by-products, aflatoxin is as high as 300 ~ 500 PPD, which is 20 times of the national standard10, which will seriously affect the reproduction and development of fur animals. Third, improve comprehensive quality and cultivate scientifically. In the future, the competition between special aquaculture will be the competition of comprehensive quality, scientific and technological content and accuracy of information prediction of farmers. Only by subscribing more magazines and periodicals, surfing the Internet, attending more meetings, mastering first-hand data and information, and making scientific predictions, can we improve our comprehensive competitiveness and anti-risk ability. Every special animal has its own unique living habits. It also determines its particularity in feed, feeding, management and medication. Pay special attention to feed. Although there is no national mandatory nutrition standard for fox, fox and mink feed so far, some domestic manufacturers who have been producing fur animal feed for a long time and have a large production scale have basically met the needs of animal growth and production on the basis of a large number of animal feeding experiments and application in many farms through continuous experience accumulation and variety adjustment. As long as it is scientifically matched and reasonably used, the ideal effect can be achieved. Fourth, give play to the role of trade associations, broaden channels and jointly sell. In the case of unstable or depressed fur market, trade associations are playing an increasingly important role in the unified procurement of feed and vaccines; Communicate with each other to improve the breeding level; Farmers should cooperate with Qi Xin to broaden the circulation channels, adopt the way of joint sales, give full play to the advantages of "measuring skin", reduce the circulation links, and increase and create their own benefits. Don't compete to sell at a low price. As a result of unfair competition, the seller's market will suffer more. Conditional farmers can also preserve or increase the value of hides through deep processing and finishing. We should also pay attention to the economic value of developing by-products. Five, pay attention to the application and promotion of new technologies and new achievements, scientific use of feed, reduce the cost of feeding. In recent years, the price of fresh fish and fishmeal has been rising all the way, especially the price of fur dropped sharply in late 2006 and early 2007. Everyone is complaining that foxes and minks can't be kept. The fact is not that minks and foxes can't keep fish. As long as we know and master the nutritional composition and content of fish and scientifically allocate feed, we can also raise high-quality fur animals. For example, this year, Zhong Xu Company joined Northeast Forestry University and American Soybean Association. The technicians of feed manufacturers constantly develop new products, such as refined feed and concentrated feed, to meet the market demand. These products can make full use of local feed resources and reduce feeding costs. As long as farmers choose fresh raw materials with high quality and low price and scientifically allocate them under the guidance of technicians, the effect will be more ideal today when fur prices fall. On the basis of scientific use of compound feed, farmers will use their brains to develop other feed resources according to the specific conditions of each place, and reduce the cost as much as possible, and probably get some benefits. For example, we need to pay close attention to the prices of fresh fish and fishmeal. After conversion, when the price of fresh fish exceeds the price of fish meal, reducing the consumption of fresh fish and supplementing fish meal can reduce the feeding cost. At the same time, there are also some problems that need to be reminded: namely, changing the animal's thin diet and advocating feeding heavy food to increase dry matter intake and improve production performance; Attention should be paid to the supply of trace elements and vitamins during the breeding period and the early breeding period of young animals to avoid reproductive diseases and growth obstacles; Using milk substitute feed during the period of 20-60 days can reduce birth mortality, increase weaning weight, promote growth and development, and obtain larger skin; Through scientific feeding, the feeding cost can be reasonably reduced and high-quality fur can be produced. Finally, I'd like to send you a sentence from Song of Luxi Fur Animal Research Association in Liaocheng. The management mainly pays attention to two things: one is to buy high quality and low price feed; Second, there is patience when the selling price of leather sheets is high; Perseverance when unsalable; There is a sense of normality in preserving capital and making small profits. According to experts' opinions and market analysis, this paper briefly introduces the mature fur animal breeding projects in recent years: mink, fox, raccoon dog and rex rabbit are the main representatives of fur animals. Up to now, there are a large number of mink skins in the fur market, and the price has risen steadily, and the sales of improved blue fox are smooth. The litter rate of silver fox is relatively low, but the price of silver fox skin is relatively stable in recent years due to the decrease of stock. Raccoon is the easiest fur animal to breed, and the breeding cost is low, but the price fluctuates relatively. Judging from the development of raccoon dog breeding in recent years, the application scope of products is expanding and the demand is increasing. It is a good project for family farming and rural poverty alleviation. Mink is a relatively stable breed, and it is expected that the stock of mink will increase due to the stable price of mink. The improved blue fox produced by crossing Finnish blue fox with local blue fox will be welcomed because of its large skin and good wool quality. This year, the price of common raccoon skin in Wusuli is expected to be good, and farmers will also have good economic benefits. Especially raccoon dog breeding will be the star species in fur animal breeding this year. Judging from the development trend of fur animal breeding industry, mink breeding industry has the fastest development, and mink accounts for about 70% of the total fur trade in the world. Raccoons are omnivorous animals and are easy to raise and breed. They can give birth to 6-8 cubs with an annual output of 1. By the end of the year, they can sell leather as a commodity and put it into production that year. The general profit rate is 30% ~ 100% of raccoon output, which is suitable for rural individuals. Rex rabbit is a fur animal suitable for rural development, with both skin and meat, good fur quality and strong reproductive ability. It breeds 5-6 a year, and each one gives birth to 6-8. Small size, small occupied space, suitable for three-dimensional culture and short feeding cycle. Generally, a female rabbit can breed 5 fetal rabbits and at least 30 adult rabbits a year. According to 40 yuan's calculation, the gross income of a female rabbit can reach about 1.200 yuan a year. However, the quality of rabbit skin and feeding technology have great influence on the breeding efficiency of rex rabbits. In order to successfully breed fur animals and maximize breeding benefits, we must pay attention to introducing excellent provenances, because the market prices of good skins and second-grade skins are quite different. At the same time, we must carry out scientific breeding, scientific selection and reasonable hybridization, adjust breeding varieties according to changes in market supply and demand, expand the production of breeding varieties with large market demand, and increase breeding benefits. Reasonable introduction can effectively improve economic value. For example, when raccoons are introduced, white male raccoons and ordinary Wusuli female raccoons can be introduced; Introducing Finnish male fox and domestic blue fox or improving blue fox; Introduce red fox male fox and blue fox silver fox female fox to cross.
