Let me first talk about the understanding of animal science: animal science is an important branch of life science. Its basic task is to provide high-quality and high-quantity animal products for human beings on the basis of understanding and mastering the life laws of animals such as genetic variation, growth and development, reproduction, digestion and metabolism. Animal science aims to meet people's growing demand for high-grade meat diet, and mainly carries out animal nutrition and feeding research, feed resource development, feed distribution, animal science professional formula and feed technology design, feed and feeding enterprise management and so on. Through a large number of animal experiments and livestock and poultry production practices, you will understand the physiological characteristics and living habits of rabbits, rats, horses, cows, pigs, chickens and even cats and dogs, and learn the scientific methods of raising, managing and helping them reproduce. Recently, the research and production of green meat food is very popular. Animal science pays more attention to the comprehensive application of related technologies, while management science research needs to pay attention to the overall layout; At the same time, I hope you have a passion for animals and a certain practical ability. 2 1 century, animal science is developing vigorously, and the future of such professionals is limitless. This will be very important for learners to accumulate practical experience in production and cultivate the ability of comprehensive analysis and problem solving. With the progress of science and technology, the research field of animal science has expanded from the traditional animal husbandry to the breeding, breeding and product processing of aquatic animals, rare birds and animals, companion animals and ornamental animals. The depth of research ranges from the whole animal level, cellular level, subcellular level to molecular level, so that people can understand the laws of animal inheritance, development, reproduction and metabolism at the gene level. The successful cultivation of cloned animals and transgenic animals shows that animal science is one of the most challenging and promising fields in life science in 2 1 century. Second, talk about the current situation and shortcomings of China's animal husbandry development. Since the reform and opening up, due to the adjustment of policies, the increase of national investment, the popularization of livestock and poultry varieties, the progress of epidemic prevention and hygiene, especially the scientific and technological progress of animal nutrition and feed, the output of livestock products and aquatic products has been greatly improved. According to the statistics published by FAO in 2000, there are 450 million live pigs on hand and 520 million live pigs are slaughtered, ranking first in the world with a slaughter rate of 1.22%. Sheep10.27 billion and goats10.49 billion, ranking first in the world. Cows/kloc-0.04 million, the third in the world; The stock is 4 billion, ranking first in the world. The total meat output has been ranked first in the world since 1990, reaching 70 million tons, accounting for 28% of the world's total meat output. The per capita level of meat, eggs and milk has obviously improved, with 48.34 kg of meat per capita, including 4.05 kg of beef, 0/.965,438+0 kg of mutton, 32.93 kg and 9.45 kg of pork. Poultry. Milk 7.23kg；; Egg 14. 16kg is also at the level of developed countries such as China. The total amount of aquatic products reached 4 1.22 million tons, the total output of aquatic products ranked first in the world, and the output of aquaculture ranked first for ten consecutive years. It is also the only country in the world where aquaculture production exceeds fishery production, and the per capita possession of aquatic products is 3 1 kg, which is slightly higher than the world average. The slow development of China's animal husbandry production from the planned economy period to the rapid development in the transition period to the market economy shows that China's economic system reform has played a powerful role in promoting the development of productive forces and formed a huge production scale pattern of China's animal husbandry. 1, the growth mode of animal husbandry has changed obviously. In recent years, under the guidance of national policies, many places in our country, while consolidating and perfecting the established animal husbandry communities, have started to build county-level standardized breeding communities with the idea of promoting the whole village and moderate scale in accordance with the requirements of unchanged development mode, undiminished support and unrelenting work assessment. Through relevant measures such as "hook guidance, technical service, financial support, standardized production, and expanded sales", farmers will be driven to expand the scale of production and operation, improve the quality of livestock products, increase the efficiency of breeding, promote the standardized production process of animal husbandry, and make a breakthrough in standardized breeding. At the same time, by taking measures such as funds, technical support and tax incentives, we will cultivate and support leading livestock products processing enterprises, and build bridges between large-scale farmers, processing enterprises and markets, so that livestock products processing enterprises will continue to grow.

2. New progress has been made in the development and utilization of pasture. Judging from the development and utilization rate of forage resources, China's animal husbandry has broken the traditional breeding mode, combined with the scale, and vigorously promoted practical technologies for forage development such as forage planting, silage ammonification and biological fermentation. That is, strengthen the screening and popularization of new forage varieties and plant them in large quantities; Straw used as fuel and fertilizer in the past is used as high-quality feed for livestock and poultry after silage ammoniation and fermentation; Increasing biological fermentation and popularizing the technology of changing cooking into living feed have promoted the development of herbivorous livestock and poultry such as cattle, sheep and rabbits. 3. Animal epidemic prevention has been strengthened, and the standardized production of livestock products has started well. Since 1998, many counties and districts in China have seriously organized and implemented the construction project of animal epidemic areas without regulations issued by the Ministry of Agriculture for nine consecutive years, and the level of epidemic prevention and elimination has been greatly improved. In the case of conscientiously publicizing and implementing national standards and local standards, we will strengthen management and strictly control, and strictly follow the standards in all aspects from feed site selection and construction to feed medication and epidemic prevention. It laid a solid foundation for the full implementation of standardized production of animal husbandry. 4. However, China's animal husbandry is still in the stage of individual and single management, with small scale, extensive management, insufficient funds, low economic benefits and lack of market competitiveness. Although specialized and intensive farms have appeared in some areas, the foundation is poor and weak, and there are many factors affected by the whole environment. Compared with developed countries, there is still a big gap. Germany, the Netherlands and other countries are equally vast and sparsely populated, and their population density is 0.9 times and 2 times higher than that of China respectively, but they are all big and powerful countries in animal husbandry in the world, and the output value of animal husbandry accounts for more than 70% of the total agricultural output value. In other countries, such as the United States accounting for more than 50%, Sweden accounting for more than 75%, Ireland accounting for more than 80%, Denmark and New Zealand accounting for more than 90%, the output value of animal husbandry in China accounts for only 3 1% of the total agricultural output value, which is only the level of developed countries in the 1970s. Therefore, to solve the agricultural problems in China, we must increase the proportion of the output value of animal husbandry.
