Comparison of febantel tablets and Vercom paste against gastrointestinal nematodes of dogs.     

E C Greiner  D G Brenner  D D Cox  D L Heaton-Jones 《Veterinary parasitology》1992,41(1-2):151-156

Thirty adult dogs with naturally acquired gastrointestinal nematode infections were assigned at random to ten replicates and treated daily for 3 days with either a combination febantel/praziquantel (Vercom) paste, febantel tablets or placebo tablets. Numbers of hookworm and whipworm eggs after treatment were reduced similarly for both drug formulations when compared with pretreatment egg counts, whereas these counts increased in the controls. Vercom paste reduced the hookworm egg count by 99.9% and the whipworm egg count by 99.6%. The febantel tablet decreased the hookworm egg count by 99.9% and the whipworm egg count by 100%. As determined at necropsy, the controlled test efficacy against adult hookworms and whipworms was similar for the Vercom paste and the febantel tablets. The controlled test efficacies of Vercom paste against Ancylostoma caninum, Ancylostoma braziliense, and Trichuris vulpis were, respectively, 99.7%, 100% and 95.8% and those of febantel tablets were 98.2%, 100% and 99.7%. These results indicate that the nematocidal efficacy of febantel against these nematodes remains unchanged in these two formulations. No adverse reactions to either febantel tablets or to Vercom paste were observed.  相似文献   

Behaviour of the false rig: causes and treatments     

J E Cox 《The Veterinary record》1986,118(13):353-356

The false rig is a castrated horse which shows masculine behaviour of one sort or another. The behaviour patterns reported to the author by owners of such animals and the possible causes are discussed here. Some such horses can show all the behaviour patterns of the entire, including erection and intromission. Evidence is presented that the behaviour is not hormonally induced or hormone dependent. The thesis is put forward that the behaviour shown is part of the normal social interaction between horses and possible treatments are discussed in the light of this possibility.  相似文献

Implications of rising costs of registering agrochemicals     

A.C.I. Samuel  B.W. Cox  H-H. Cramer 《Crop Protection》1983,2(2):131-141

The increased number and complexity of the requirements for registration of agrochemicals are causing a steep rise in the costs of research and development and therefore in the price of agrochemicals. It now takes about 8–9 years for an agrochemical to be developed and marketed, at a probable cost of 10–20 million US dollars, and each of the individual tests required may cost up to US$ 500 000. A continuation of these trends would have serious consequences for industry, farmers, consumers and the developing countries. So far, the agrochemical industry has been able to continue to produce the new and improved materials necessary to combat changing pest attack: whether it can continue to do so may depend upon whether or not registration requirements are increased. Unnecessary requirements must be identified and eliminated, and any new demands must be fully justified in terms of the cost involved and of the ensuing benefits. However, if the search for greater safety were to be pushed to even greater lengths, so that costs exceed what the market will bear, the extra costs would have to be borne by the authorities and, ultimately, by the taxpayer.  相似文献

Minimal nitrogen requirements of Corynebacterium renal strains   总被引：2，自引：0，他引：2  

W P VanEseltine  W M Cox  S Kadis 《American journal of veterinary research》1978,39(1):123-127

Corynebacterium renale strain 10849 was grown in a chemically defined medium containing glucosamine, ammonium sulfate, and 5 amino acids as possible nitrogen sources. Although glucosamine was slightly stimulatory, its omission from the medium had a minimal effect on growth, and washed cells introduced into glucosamine-free medium grew readily through 10 serial transfers, demonstrating that this compound was not required for growth. Individual omissions of isoleucine, valine, methionine, and glutamine resulted in lengthened lag periods and reduced growth rates in initial transfers, but recovery occurred in subsequent serial transfers so that by the 3rd or 4th transfer, growth rates and cell crops were only slightly less than in control cultures in complete medium. Omission of cystine resulted in a permanently low growth rate and reduced cell crop, but this was remedied by substituting various nonnitrogenous compounds containing reduced sulfur. Strain 10849 and 6 additional strains were then serially cultured in a minimal defined medium in which sodium thioglycolate provided reduced sulfur and ammonium sulfate served as sole nitrogen source. Since only ammonium ion was required as the nitrogen source, it could be concluded that C renale, which rapidly hydrolyzes urea, should find an adequate source of nitrogen for growth in the urinary tract of animals.  相似文献

Immunocompetence of fattening pigs fed organic versus conventional diets in organic versus conventional housing     

Millet S  Cox E  Buyse J  Goddeeris BM  Janssens GP 《Veterinary journal (London, England : 1997)》2005,169(2):293-299

The effect of organic or conventional feeding on the immune response of pigs was determined using organic or conventional housing in a pig fattening unit. The experimental design involved four pens of four animals per housing and diet combination (organic housing and organic nutrition; organic housing and conventional nutrition; conventional housing and organic nutrition and conventional housing and conventional nutrition). The IgM, IgA and IgG responses against intramuscularly injected bovine thyroglobulin were determined as indicators of the antigen-specific immune responsiveness. Some general health and welfare related parameters were evaluated by measuring haptoglobin concentrations at selected times; blood lactate concentration was measured at slaughter. Conventional housing led to a higher IgG response three weeks after the first immunisation. Organic housing led to lower haptoglobin and lactate concentrations at slaughter, indicating a higher stress resistance in these pigs. No major differences between the two feeding types were found. We conclude that the immune responses following either a conventional or an organic diet are comparable, whereas organic housing can increase stress resistance at slaughter compared to conventional housing.  相似文献
