Abstract:

To know the prevalence of gastrointestinal parasites in Hu sheep from stall-feeding farms,a total of 553 fresh fecal samples from part stall-feeding farms in Henan were collected and examined the presence of eggs or oocysts using centrifugation method,saturated salt solution floatation technique,Sheather's sugar flotation technique,Lugol's iodine-solution staining method and McMaster's method.The results showed that the overall infection rate of gastrointestinal parasites was as high as 97.47%,and 75.23% of the samples were mixed infection,samples mixed infections with up to 5 species of parasites.A total of 7 species of parasites,Coccidia,Cryptosporidium,Giardia,Amoeba,Whipworm,Nematode and Moniezia were found to be 90.42%,0.90%,4.88%,65.64%,12.48%,42.13% and 4.88%,respectively.The highest infection intensity was Coccidia,and its highest number of oocysts per gram(OPG) of feces was 652 000,followed by Nematode,and the highest number of eggs per gram (EPG) of feces was 7 000.There was no significant age and gender difference in infection rate of gastrointestinal parasites in Hu sheep (P>0.05).The seasonal epidemic dynamics showed that the parasitic infection rates in spring,summer and autumn were different from those in winter.In conclusion,parasitic infections in the digestive tract of Hu sheep were more common,and effective comprehensive prevention and control measures should be taken to ensure the healthy development of the flock.
