The Study Of Investigation And Control Of Enteric Parasites Of Pigs Farms In Animal Husbandry Sport

Enteric parasites of swine have a vital effect on large-scaled pig farms, It restricts the economic benefits of pig farms, The main clinical symptoms are diarrhea?lankness and some serious lesion of organs, such as liver and lung, badly affecting the health of pigs. Some of enteric parasites are Zoonotic parasitic diseases, it have brought huge hidden danger and harm to human health. In view of those, it's a important step to know the swine enteric parasites'infection situations and epidemic characteristics of large-scaled pig farms, make effective measures to refine the enteric parasites. It could surely important reference for reducing enteric parasites'infection rates of large-scaled pig farms,From 2013 to 2015,1246 stool samples collected from large-scaled pig farms were examined by using Precipitating and floating method.The main results of this essay are listed as follow:1. The investigations on enteric parasitical infection of swine from large-scaled pig farmsThe results showed that six species of enteric parasites had been examined, the infection rates of Ascaris suum, Oesophagostomum, Trichocephalus, Strongyloides, Eimeria suis and Balantidium coli were 8.27%,6.90%,5.06%,4.57%,17.09% and 22.71%. piglets could be infected more easily by fattening pigs, The infection of enteric parasites is different because of different surroundings of large-scaled pig farms2. The investigations and analysis of controlling patterns of enteric parasites in large-scaled pig farms.We learned about different controlling patterns of enteric parasites from nine different large-scaled pig farms to provide a effective and reasonable controlling patterns of enteric parasites for Animal husbandry sport. We made a conclusion that the infection of parasites in large-scaled pig farms could be effectively controlled by using the drugs of Ivermectin, under a wonderful administration.3. Survey of the comprehensive controlling pattern in large-scaled farms.According to the epidemic rules, characteristics and the periods of Parasites, in order to enhance the immunity of pigs. A effective comprehensive controlling pattern was proposed that we should choose appreciate drugs, controlling Patterns of Parasites, monitor the infection rates of Parasite and improve management of the pig farms.4. The experiment of comprehensive controlling pattern.We selected two pig farms to carry out the experiment, and pay more attention to piglets and sow. The main measures were listed as follows:1. Selecting Ivermectin as parasiticide.2. Adopt periodic parasites controlling pattern.3. Monitoring the infection rates of parasites.3. All pigs taking parasiticide after buying, then living with other pigs.4. Enhancing the management and the undefiled living surroundings on the farms.5. The waste should be piled to ferment.The results showed that less enteric parasites had been defected than before. The fatting pigs had a faster speed of growth but a lower fodder consuming after two years of test, each pig added some money. It was obvious that the comprehensive controlling pattern of the enteric parasites was not merely theoretic value but economic value.
