In the intensive cultivation of cattle and sheep, there will be many pollutants, of which the excreta is the most important pollution. In addition, there are odors, drug residues, and waste from the processing of livestock products. Common pollution Drainage. Every day, cattle and sheep consume a large amount of forage, feed, etc., which will produce a large amount of fecal urine excretion. Especially dairy cows excrete more dirt. odor. The odor produced by the production of cattle and sheep, including the odor of cattle and sheep's excreta and urine, the bad smell of feed spoilage, etc. These odors not only endanger animal health, but also affect the lives and work of the surrounding residents. They are an important issue in the control of waste in cattle and sheep breeding. Other sources of pollution. 1. Biological contamination. Animals like birds, rodents, cats and dogs, and wild birds can enter and leave farms, carry disease-causing viruses, and re-distribute viruses directly or indirectly, causing further spread of the epidemic. 2. Feed pollution. If the Amino Acid levels in the protein feed are not balanced, the unmatched amino acids will be excreted after they are degraded in vivo. This not only reduces the utilization of feed protein, but also causes nitrogen pollution to the environment. In addition, most of the plant acids that cannot be absorbed by the animals in the grains are excreted in the faeces, causing phosphorus pollution to the environment. 3. Feed additive contamination. Trace element additives can also increase environmental pollution and harm the environment. Moreover, in the process of promoting the growth and development of cattle and sheep, and pre-controlling various diseases, hormones, antibiotics, and other drugs are often used in feeds. If they are abused, they will cause even more serious damage. Environmental pollution control measures Improve production pollution management measures. The local aquaculture management department shall formulate practical pollution management measures. When approving a construction site, it is necessary to do a good job of reviewing the relevant systems and facilities, and formulating specific management measures to implement specific measures to strengthen the monitoring and inspection of environmental pollution. The scale of breeding varies according to the specific circumstances, but if the scale of the breeding exceeds the scale expansion, the density of breeding will be increased indefinitely, which will in turn induce the breeding of epidemics, aggravate the surrounding ecological capacity, and ultimately reduce the breeding efficiency. Therefore, the cattle and sheep farms of different scales should clearly identify the sewage treatment capacity and treatment facilities that should be achieved, and reduce the contamination of the surrounding environment by the farm sewage by rationalized layout. Promote ecological farming system. Excreta is the main source of pollution in cattle and sheep production. For the pollution of pollution sources, it is recommended to establish an ecological breeding system. Through the promotion of ecological farming systems, it will reduce the pollution of excreta to the environment, and even change waste into treasure, produce biogas and increase fertility. The so-called ecological breeding system is to follow the principles of ecology, establish ecological livestock farms, realize multi-level recycling of waste, and achieve the purpose of effective treatment and use of animal excrement. For example, the harmless treatment of cattle, sheep and feces and urine, or the production of biogas through anaerobic fermentation can not only purify the environment, but also obtain bioenergy. Promote the use of scientific feed formulations. With reference to the ideal protein model of digestible nitric acid content, a reasonable balance of the ratio of cattle and sheep diets, improve the comprehensive utilization of feed, reduce the discharge of nutrients, thereby reducing environmental pollution. During the use of diets, it is necessary to further improve the use of additives, specify operative testing procedures, strictly control the use of trace elements in diets, antibiotic additives, etc. to reduce the use of any direct or indirect threat to human health. Various additives. In addition, the development of new non-hazardous additives is also a feasible way to reduce environmental pollution. In recent years, Probiotic additives, Chinese herbal medicine additives, etc. have come out one after another and have achieved good results. In comparison, probiotic supplements can effectively improve digestive tract colonization in animals, balance the beneficial microbial flora in the intestine, achieve the goal of bacterial treatment, and have no chemical residues and drug resistance, and the use effect will be better. Chinese herbal medicine additives also have the characteristics of low chemical residues, no resistance to drugs, and are worthy of promotion. Do a good job of storing and releasing feces. After the excrement has been removed, it must be stored in a septic tank for storage before fertilization. Septic tanks are required to be stamped and encrypted to avoid excessive odor spillage, resulting in flies, odors and other pollution of the surrounding environment. There should be a certain distance (200m~300m) between the cattle shed and the storage tank, and the bottom and sides of the storage tank should be sealed to prevent leakage of groundwater. The volume of the storage tanks for dairy cows may be 0.04 cubic meters per 454 kg of body weight per day. Together with the cowshed operation sewage, the actual design is about 0.06 cubic meters per day. In addition, some additional capacity is required to accommodate the sewage in the milking parlor. The amount of sewage in the milking parlour is related to the equipment used. If the breasts are scrubbed with paper towels and disinfectants, the amount of sewage is minimal; if the breasts are cleaned with automatic equipment, the resulting sewage from each cow will be about 41 liters. When building or expanding a cattle farm, priority should be given to handling of the waste. If the discharged water is used as fertilizer in the nearby agricultural land, the area of ​​the required agricultural land must be considered according to the scale of the farm, and the scope of fertilization should be expanded as much as possible. To minimize the discharge of waste water. Water accounts for a major portion of the waste volume, and cattle farms require large amounts of water even for regular cleaning of milk storage and milking parlours. Therefore, the use of flushing water should be improved and the amount of water used should be reduced. Unless necessary, cattle should not be flushed with water, and water that does not contribute to the improvement of system function should be reduced to the faeces, and the rainwater must be separated from the sewage. The reduction of clean water into the manure treatment system can effectively reduce the discharge of waste water. Of course, it is also possible to store rainwater as flushing water. At this stage, recycled water reuse has become one of the accepted methods for reducing treatment facilities and fecal loads. In addition, recirculating water can be mixed with fresh water for other purposes. Freeze-dried powder is a sterile powder injection obtained by freezing the liquid medicine into a solid state in a sterile environment, and subliming and drying the water in a vacuum. Freeze-dried powder is composed of a bottle of high-purity and high-active biological protein freeze-dried powder and a high-purity liquid essence. When using, it needs to be connected with a patented vacuum to reconstitute the freeze-dried powder and the essence to activate the biological protein activity.
