genetic diversity in and conservation strategy considerations for navajo churro sheep.the objectives of this study were to 1) evaluate the genetic diversity of navajo-churro sheep using pedigree information; 2) examine the distribution of the navajo-churro population; and 3) evaluate the effect of breeder dynamics on genetic conservation of the breed. pedigree data and breeder information (city and state) were obtained from the navajo-churro sheep breed association. inbreeding coefficients were calculated for each individual animal using pedigree information. a geographic informa ...200415484940
enzootic toxoplasmosis in sheep in north-central united states.of 1,564 serum samples from adult ewes from 33 farms in iowa, minnesota, south dakota, kansas, and nebraska where toxoplasmosis-induced ovine abortions had been diagnosed, 65.5% were found positive for toxoplasma gondii antibodies using the modified agglutination test. toxoplasma gondii antibody titers of ewes were: less than 64 (34.5%), 64 (14.9%), 256 (22.0%), 1,024 (14.5%), and greater than 4,096 (13.8%). thus, 28.3% of sheep had high titers (greater than 1,024) indicating recently acquired t ...19892795369
