managing replacement stock within the environment of the south--plant, soil, and animal interactions: a review.the south extends from the atlantic coast and the gulf of mexico north through virginia and kentucky and west to the 100th meridian, which extends through texas and oklahoma. the soils, environment, and range of adapted forage species offer many and varied opportunities for designing forage-livestock systems for rearing replacement stock. anti-quality factors of concern when using forages for replacement stock include the presence of acremonium coenophialum (morgan-jones and gams) in tall fescue ...19938270541
rabies surveillance in the united states during 2004.during 2004, 49 states and puerto rico reported 6,836 cases of rabies in nonhuman animals and 8 cases in human beings to the cdc, representing a 4.6% decrease from the 7,170 cases in nonhuman animals and 3 cases in human beings reported in 2003. approximately 92% of the cases were in wildlife, and 8% were in domestic animals (compared with 91% and 9%, respectively, in 2003). relative contributions by the major animal groups were as follows: 2,564 raccoons (37.5%), 1,856 skunks (27.1%), 1,361 bat ...200516379626
allelic variants of ovine prion protein gene (prnp) in oklahoma sheep.1,144 sheep belonging to 21 breeds and known crosses were sequence analyzed for polymorphisms in the ovine prnp gene. genotype and allele frequencies of polymorphisms in prnp known to confer resistance to scrapie, a fatal neurodegenerative disease of sheep, are reported. known polymorphisms at codons 136 (a/v), 154 (h/r) and 171 (q/r/h/k) were identified. the frequency of the 171r allele known to confer resistance to type c scrapie was 53.8% and the frequency of the 136a allele known to influenc ...200314970685
distribution patterns of imported fire ants (hymenoptera: formicidae) on a sheep and goat farm in oklahoma.imported fire ant colonies were quantified in 1,000-m(2) circular subplots spaced approximately 125 m apart on a sheep and goat farm in oklahoma. social form (percent polygyny), mound density, cumulative above-ground mound volume, and average mound volume were subjected to multiple regression analyses to examine trends related to landscape metrics and habitat characteristics. monogyne populations were spatially autocorrelated, and polygyne mounds tended to be smaller and more numerous. a model i ...200919508763
susceptibility of amblyomma americanum to natural and experimental infections with theileria cervi.one hundred fifty amblyomma americanum were examined between march and september 1986 from cookson hills wildlife refuge in eastern oklahoma (usa). of these ticks, 11% (17 of 150) were infected with theileria cervi. field-collected nymphal ticks had an 8% (3 of 37) prevalence of infection averaging 1.0 infected acini/nymph. female ticks had a 16% prevalence of infection averaging 1.6 infected acini/female; t. cervi was not observed in salivary glands of field-collected male ticks. when laborator ...19883193564
