The cattle farm should constantly improve the quality of the herd. In the production, the frozen sperm of the good breed bull should be selected for breeding. It must not be ignored that it must be given enough attention. After the cattle farm has been properly constructed, it is necessary to adopt epidemic prevention measures against the cattle system to control the epidemic and spread of the disease and improve the economic benefits of the cattle farm.
1 Reasonable structural requirements for cattle farms
1.1 Construction requirements
Before the construction of the cattle farm, the wind direction, water flow, residential area and other factors should be considered comprehensively. In addition, the construction of the new rural area should be taken into account in the planning of the site. The site selection should strive to avoid the good cultivated land and the farming and animal husbandry. Combine as a starting point to support the development of the crop industry. The size of the cattle farm should be selected according to the specific level of economic, cultural and management level. The management and technical improvement of the cattle farm should be realized through the training of personnel, so it is necessary to determine the appropriate breeding scale. If we expand the breeding scale of the cattle farm, we can better implement advanced technology, which not only can improve efficiency, but also save certain resources, and improve product quality and increase economic benefits to some extent. The managers of the cattle farms should have sufficient breeding knowledge and breeding experience. Otherwise, if the capital turnover is difficult, it will be difficult to achieve the expected economic benefits and cause a certain degree of loss.
1.2 Herd composition
The reasonable structure of a typical-scale dairy farm: 55% to 60% of adult cows, and 1 to 2 cows in adult cows account for 40% of the total number of cows, and 3 to 5 cows account for the total number of cattle. 40%, 6% or more accounted for 20%. The old and weak disabled cattle in the herd should be eliminated as soon as possible according to relevant regulations, so as to ensure the continued high yield and stable production of the cattle. Young cattle refer to cattle from 18 to 28 months old, accounting for about 13% of the entire herd. Large bred cattle refer to cattle from 12 to 18 months old, accounting for 9% of the entire herd. Xiaoyucheng cattle refers to cattle of 6~12 months old, which should account for 9% of the whole herd. Yak points out that cattle aged 1 to 6 months old should be considered according to the production performance of their parents and the appearance of the body, and then reserved as a reserve cow. Other yaks that have not been selected should be as soon as possible. Sold out, the yak reserved for the reserve cow should account for 9% of the entire herd.
1.3 Herd Improvement
First, you should check the bull's pedigree to avoid inbreeding. Many years ago, China has implemented a good-quality subsidy project for the improved species of Holstein cows, and further promoted the large-scale promotion of high-quality dairy cows. Over the years, many large-scale cattle farms and parks have received economic subsidies. The cattle farm should make a good record of the breeding of the cattle, so that the frozen essence can be selected more reasonably, and the frozen essence which is excellent in variety but not expensive is selected. It is also necessary to check whether the selected bulls have a descendant measurement record to determine the quality of the bulls. The frozen sperm of the bulls determined by the descendants is widely used in the cattle farm, so as to ensure that the offspring cattle have a higher milk production level. The genetic quality of the herd should be continuously improved in production. It is not blind to pursue the high milk yield of dairy cows. The genetic level of frozen bulls should be higher than that of cows; the genetic quality of frozen bulls should be higher than that of bulls used before the scale dairy farms, so as to ensure the continued The genetic level is improved, and the number of milk in the cows can be gradually increased after several improvements in clinical production. In addition, the dairy farms are required to have professional technicians with strong technical skills and strong sense of responsibility. It is not allowed to hire unemployed and poorly skilled employees.
1.4 Reproduction management
Breeding work is very important for cattle farms. In practice, some poor quality adult cows should be eliminated, and then the born calves should be converted into bred cattle or commercial cattle for sale. However, the bred cattle are converted into cattle or fattening cattle, which are finally processed in the form of slaughtering and selling, which can ensure the continuous change of the herd structure, which is more conducive to the breeding management of the herd, but it must be carried out according to plan. turnover. Large-scale dairy farms must also continuously strengthen the feeding and management measures of dairy cows, and often observe the estrus cows to ensure that the breeding measures are taken at the right time, and the number of days of postpartum emptying of the cows should be shortened as much as possible, thereby further shortening the interval of calving. . In the actual clinical production process, the number of young cows must be mastered. In addition, the frequency of renewal of adult cows should be reduced, and the updated parity of adult cows should be adjusted. According to many years of understanding, many dairy farms of many scales pay more attention to breeding and calving, but they rarely adopt the active elimination mechanism on the market. In fact, this is an incorrect concept. Managers should establish a correct understanding of heavy quality and light quantity. For dairy cows with long-term infertility and chronic reproductive diseases in the dairy farm, they should adopt elimination measures to further improve the economic benefits of the cattle farm. In particular, for cows with an empty stomach of more than 140 days, the specific cause must be ascertained. If it is determined that there is no reproductive capacity after inspection, the elimination treatment should be adopted as soon as possible and as soon as possible to improve the economic benefits of the large-scale cattle farm.
1.5 feeding technology
At present, the full-mix ration feeding technology has been fully implemented in most of the cattle farms in China. This technology can provide the nutrition needed by cattle for different growth and development of the herd and the lactation stage. The formula is designed by experts. Grain blending is a special blender for cutting mix and feeding, so the fully mixed diet feeding technique is currently a relatively advanced feeding process, but it has also been accepted and adopted by most pastures. The use of fully mixed ration feeding technology ensures a balanced diet nutrition, which has a significant boost to the management and production levels of the cattle farm. It also saves the feed of the cattle farm and reduces feed costs for the health of the herd. The situation has a significant improvement effect.
2 Health and epidemic prevention requirements for cattle farms
2.1 Sanitary management of the site
The cattle farm should be prepared by professionals according to the specific conditions of the site, so that it can form the standard of daily health management and assessment. In addition, the corresponding site health inspection plan should be formulated to specify the specific inspection time and Items that need to be inspected to ensure strict enforcement, and work habits to make relevant records are required for future inspections. Roads and courtyards around the cattle farm and in the cattle farm are required to be kept clean at all times. Clean the excreted waste of cattle in a timely manner and take harmless treatment. The faecal pool of the cattle farm should be cleaned every week, otherwise it will pollute the cattle farm and its surrounding environment; if the biogas digester is built on the urinal pool, the faeces discharged from the steak can be fully utilized. The environment around the barn should be thoroughly disinfected on time.
2.2 Treatment of feces and urine
The manure from the steak can be used as a fertilizer because the manure is rich in nitrogen, phosphorus, potassium and organic matter. If the cattle farm treats it properly, it can naturally be used as a very good organic fertilizer. In addition, the faeces of the steak are rich in crude fiber, and when the manure is collected, there is naturally a mixture of litter, cow hair, feed residue and gravel. Therefore, these feces must be effectively pretreated before being placed in the biogas digester. When faeces are subjected to anaerobic fermentation, pathogenic microorganisms and parasites can be killed. The biogas generated in the process can also be used as fuel and power generation lighting, saving energy while maintaining cleanliness without causing any pollution. After the manure is treated, the slag juice will have a lot of trace elements such as phosphorus and sulfur and vitamins, which can become very good bait and animal feed in the fish pond, which can reduce pollution, save energy and improve economic benefits.
In the daily production process of the cattle farm, there will naturally be a lot of urine and production sewage generated by the steak. If the effective control is not carried out, it will pollute the water around the cattle farm and affect the surrounding bio-safety. Therefore, the cattle farm must be strengthened. The management measures can require that the cow dung be cleaned as much as possible without water, and the sewage collection and treatment system can be established in the conditional field, which can effectively reduce the amount of sewage generated. In addition, the multi-stage sedimentation and solid-liquid separation operation of sewage can effectively reduce the organic matter contained in the sewage, and the necessary effective treatment measures should be taken for the sewage discharged from the cattle farm.
2.3 Epidemic prevention requirements
General requirements: The health of cattle in clinical production is directly affected by the sanitary conditions of large-scale cattle farms and the degree of pathogen contamination in cattle farms. This requires that the weeds, sewage, feces and garbage in the cattle farm must be thoroughly removed, and then effectively disinfected according to the actual situation of the cattle farm to ensure the good health of the cattle farm. In addition, it is necessary to pay attention to the hygienic condition of the cattle themselves. The cows are often brushed and should be kept clean. The staff of the cattle farm can not ignore the personal hygiene situation. They must change their overalls and work shoes before and after work to enter or appear. It is also important to ensure that the soil and water supplied to the cattle farm meet the relevant hygiene standards.
Immunization according to plan: The planned immunization of healthy cattle can effectively resist the infection of the corresponding infectious diseases. In order to achieve the desired effect of immunization, it is necessary to clarify the types of infectious diseases in the region, their occurrence season, epidemiology, and understanding the production, breeding, management and movement of the herd, so as to develop corresponding epidemic prevention plans according to needs, and timely implementation. Immunization. In addition, temporary immunizations should be performed prior to introduction or export of the herd, surgical procedures, or after complicated trauma. For animals that have not yet developed disease in the epidemic area, emergency immunization may be carried out if necessary, but attention should be paid to observe the diseased cattle in time and treat them promptly.
Improve disinfection facilities: The main purpose of disinfection is to eliminate the surface of cattle, equipment and pathogenic microorganisms, cut off the route of transmission, prevent the spread or spread of the disease, and ensure the healthy and normal production of dairy cows. The general anti-epidemic facilities of cattle farms include disinfection tanks, disinfection rooms, isolation houses, and high-pressure steam sterilizers.
Formulate a sanitation and epidemic prevention system and strictly implement it: Modern large-scale cattle farms always adhere to the concept of health and epidemic prevention against heavy pollution, and realize the protection of cattle health, promote growth and development, and have an extraordinary significance for increasing production. Today's large-scale cattle farms should pay more attention to the health and epidemic prevention of cattle farms, because as long as there is an epidemic in the cattle farm, it will cause economic losses that cannot be ignored. Therefore, we must first strengthen the understanding of bovine infectious diseases from a professional perspective, and grasp the prevalence of common infectious diseases, so as to actively control and prevent the epidemic, in order to reduce the economic losses of the cattle farm.
At present, China's cattle farms have become more and more large-scale development forms. More and more large-scale cattle farms are being built continuously. However, when building cattle farms, it is necessary to take the health of cattle as a key factor to achieve the health of the cattle. The ideal standard.
