Pigs infected with PEDv often die due to dehydration caused by diarrhea. Those that survive do not reach market weight as scheduled resulting in costs to the producer. The invention includes providing electrolyzed water either as treatment for infected animals or as a prophylactic against symptom severity in uninfected animals. The electrolyzed water is used as a substitute for or as a solution with regular drinking water. Duration of symptoms for infected pigs is markedly lessened; severity of symptoms is also reduced providing a much higher survival rate. Time to market is less negatively affected for surviving pigs than those untreated, and weight at scheduled time for sale is also less effected translating into positive financial results over those expected for untreated herds.

The invention relates to a preparation method and an application of a full-length infectious clone of a porcine SVV (Seneca Valley Virus), comprising the following steps: (1) amplification of a full sequence of an SVV / GD05 strain genome; (2) construction of infectious clone plasmid of a pSVV-GD05 virus; (3) construction of pSVV-GD05-iLOV recombinant plasmid; and (4) rescue of a parental virus (SVV-GD05) and a recombinant virus (SVV-GD05-iLOV). The method provided by the invention utilizes a strain of the SVV isolated from a Chinese pig herd to construct a viral infectious clone pSVV-GD05 withbacterial plasmid as a skeleton, and can successfully rescue the virus. At the same time, a reporter gene iLOV is inserted into an SVV infectious clone virus genome, and the recombinant SVV virus capable of expressing the reporter gene is successfully rescued. The preparation method and application of the invention provide an effective platform for deep and basic research and application of SVV, and have important scientific application value.

The African swine fever virus antibody ELISA detection kit disclosed by the invention is good in specificity, sensitivity and repeatability, the sensitivity of the kit coated with the two antigens is equivalent to that of indirect immunofluorescence detection, antibody positive can be detected earlier at a low antibody level in the earlystage, a basis is provided for clinical swine herd infection conditions, and the kit plays an important role in preventing and controlling African swine fever virus infection.

The invention provides a multi-RT-PCR method for monitoring pollution of six main viruses in a pig farm environment through one system and application. According to the method, primer design is conducted for CSFV, JEV, PRRSV, PCV-2, PRV and PPV, a multi-RT-PCR reaction system for the six viruses is established, air samples are collected through liquid collision, the viruses are subjected to separation concentration through ultrafiltration centrifugation, and the method for detecting the pollution of the main viruses in the pig farm environment is established. The method can be used for monitoring the pollution of the six viruses in air, fodder, drinking water, appliances, excrement and pig groups in the pig house and pig farm environment, and technical support is provided for establishing a main virus pollution early-warning mechanism and a main virus disease preventing, controlling and purifying system in the pig farm environment.

The invention provides a robot for healthy raising of live pigs. The robot for healthy raising of the live pigs is used for solving the problems that manual inspection of abnormal behavior characteristics of live pigs, and detection and regulation of raising environment parameters are poor in accuracy, low in efficiency and high in labor strength. The robot for healthy raising of the live pigs comprises a mobile terminal monitoring platform, an execution mechanism platform and a behavior monitoring platform, wherein the mobile terminal monitoring platform, the execution mechanism platform andthe behavior monitoring platform are all provided with wireless transmission modules, and the mobile terminal monitoring platform and the execution mechanism platform are connected with the behavior monitoring platform through the corresponding wireless transmission modules respectively. The robot for healthy raising of the live pigs can automatically and fast conduct global or local monitoring and automatic collecting on information of growth situations, behavior characteristics, raising environments and the like of pig herds and pig individuals of selected pigpens in sequence, functions of timely regulation of abnormal environments of the live pigs, fast judgement and diagnosis of abnormal behavior and diseases, early warnings against epidemic situations, and the like are achieved, and the intelligent management level of a live pig raising process is raised.

The invention discloses a method for breeding boars by means of combining constant production and visual management. The method comprises the following steps that in order to mate in a centralized manner, Regumate is continuously fed orally for 14 to 18 days, and a sow can be in heat within 4 to 7 days after stopping feeding the Regumate; when weaned sows and reserved sows are all in heat within 4 to 7 days and are mated, parturition can be completed within 4 days in a more centralized manner; a condition whether a sow group is normal or not can be known earlier by means of collecting data in coordination with a sow visual whiteboard, monitoring an impregnation grade at any time and adjusting a mating number at any time. By utilizing of the breeding method disclosed by the invention and the visual whiteboard, the amount of reserved sows is prepared can be predicted in 12 weeks before mating in advance, so that the number of the reserved sows is more precise, the management is more efficient, and the feeding cost is reduced more; centralized mating can achieve the effects that the sows deliver piglets in the more centralized manner, the uniformity is increased, the immune level is similar, the delivery work is centralized, and the labor force is less wasted, therefore the cost is lowered, the health degree of the sow group is increased, and the use of antibiotic can be reduced more.

The invention relates to a pig house timing and quantitative feeding device for livestock breeding. The pig house timing and quantitative feeding device for livestock breeding effectively solves the problems that when an existing pig house is used for breeding, feed in a feeding trough is prone to being polluted, and pigs are prone to getting sick. According to the technical scheme, on the basis that the pig house feeding device achieves timed and quantitative feeding, the top end of the feeding trough can be blocked every time when pigs stop feeding, so that invasion of flies and insects is avoided, the top end of the feeding trough can be automatically opened every time when the pigs feed, and before each time of feeding, residual feed on the bottom wall of the feeding trough can be removed in advance, the feed adhering to the bottom wall of the feeding trough is removed through a craper blade, then the feed is fed into the feeding trough, the whole device is high in automation degree, a good feeding mode is guaranteed, and meanwhile the health condition of the pigs is guaranteed.

The invention discloses a pig herd gathering detection method, which comprises the following steps: acquiring pictures of a pig house breeding field, calling a pre-trained neural network model to extract a pig herd foreground, and automatically identifying whether a pig herd is gathered or not through a classification model. The method can automatically detect whether the pig herds are piled or not, and solves the problems that at present, manual detection of pig herd piled is troublesome and laborious, and monitoring is not timely; contact between people and the swinery is reduced through automatic monitoring and recognition, disease transmission can be prevented to a certain extent, and the health of the swinery is guaranteed; meanwhile, the method can generate an accurate bunch detection result, and can provide effective and reliable reference information for pig house environmental control, swinery disease reasoning and diagnosis and the like.
