| the blowfly strike problem of sheep in new south wales. | a field survey was undertaken between 1972-76 to reappraise the nature of the blowfly problem in new south wales. for 2 years, 1972-1974, some 80,000 sheep were kept under observation and 12,481 strikes were reported, most due to lucilia cuprina. breech strike was still the basic problem but tail strike associated with scouring had become an important component where pastures have been improved. breech strike was controlled at minimal cost by managerial practices such as docking tails the correc ... | 1979 | 518435 |
| the incidence of thiabendazole resistance in field populations of haemonchus contortus on the northern tablelands of new south wales. | a survey was undertaken to assess the incidence of thiabendazole resistance in field populations of h. contortus in sheep flocks on 40 farms distributed throughout the sheep grazing area of the northern tablelands of new south wales. treatment with thiabendazole at 66 mg/kg reduced h. contortus ova output by 96-100% in 18 flocks while in the remaining 22 there was a range of responses down to levels where the anthelmintic was without apparent effect. factors which may contribute to the high inci ... | 1979 | 543833 |
| epidemiology and control of anaplasmosis in australia. | anaplasmosis occurs in those areas of northern and eastern australia infested by the cattle tick boophilus microplus but it has been studied intensively only in queensland. anaplasmosis is predominantly a disease of autumn and winter and of cattle greater than 1 year of age. the complement fixation test has been used in serological surveys of the tick-infested areas of the state. both clinical and subclinical infections occur only in tick-infested areas and they are both more frequent in bos tau ... | 1979 | 553977 |
| plasma thyroxine concentrations in grazing sheep in several areas of australia. | plasma thyroxine concentrations were measured by radioimmunoassay in plasma samples from 691 lactating ewes in 26 areas of new south wales, queensland, western australia and tasmania. sheep sampled in new south wales and tasmania had significantly lower plasma thyroxine values (4.0 and 4.3 microgram/100 ml respectively) than those sampled in queensland and western australia (5.4 and 5.3 microgram/100 ml respectively). however, sheep in some districts in southern queensland also had low plasma th ... | 1978 | 567054 |
| antibodies to akabane virus in australia. | neutralising antibody to akabane virus was shown to develop in cattle in northern australia throughout the year and also on the east coast of new south wales in the summer during 1975/1976. other species found to have antibody to akabane virus were buffaloes, horses, camels and sheep, but no antibody was found in domestic chickens, ducks, wallabies or man. the biting midge culicoides brevitarsis has been detected in all the major areas where antibody was demonstrated in this study. | 1978 | 655964 |
| a survey of antibody to aino virus in cattle and other species in australia. | a serological survey of healthy cattle in australia showed that antibodies to aino virus were present in serums from cattle in northern australia and down the east coast as far as central new south wales in 1975, 1976 and 1977, but occurred with a lower frequency than antibodies to akabane virus. in contrast to the findings with akabane virus, no neutralising antibodies to aino virus were detected in serums from camels, dogs or horses. antibodies to both viruses were detected in buffaloes and sh ... | 1978 | 718555 |
| neonatal lamb losses due to feral pig predation. | an investigation into causes of low lamb marking percentages was made on a property in north-west new south wales from 1971 to 1975. investigations revealed that from 11 to 70% of the ewes in lamb were losing all their lambs. observations suggested that feral pig predation was a factor in the perinatal loss. in 1975, 2 groups of ewes were placed in adjoining paddocks prior to lambing. feral pigs were excluded from one paddock for most of lambing by means of an electric fence. in this paddock, 11 ... | 1978 | 743055 |
| the prevalence of sarcosporidiosis in australian meat animals. | the prevalence of sarcocystis infectious in tasmanian sheep, cattle and pigs was assessed during february 1974. serological results indicated that over 90% of sheep and cattle were infected. macroscopic sarcocysts were found in 0.6% of lambs, 8.8% of 2- to 6-tooth (1 to 4 years old) sheep and 66% of full-mouth (4 years and older) sheep. the minimum prevalence in pigs, as determined by microscopic examination of muscle tissues, was 1.4% for animals less than 12 months old and 16.7% for animals ol ... | 1975 | 812465 |
