Escherichia coli bacteremia associated with hypertrophic osteodystrophy in a dog.   总被引：1，自引：0，他引：1  

K S Schulz  J T Payne  E Aronson 《Journal of the American Veterinary Medical Association》1991,199(9):1170-1173

Escherichia coli bacteremia was detected in a dog that had hypertrophic osteodystrophy. The dog improved after treatment with cephalothin sodium, iv fluid therapy, and cage rest. The cause of hypertrophic dystrophy has not been determined, although an infectious cause has been suggested. Dogs that are suspected of having hypertrophic osteodystrophy should be monitored closely for evidence of septicemia, and the administration of prophylactic antibiotics may be advisable.  相似文献

Fats and amino acids in broiler rations. 6. Synergic relationships in fatty acid utilisation     

D Lewis  C G Payne 《British poultry science》1966,7(3):209-218

A series of experiments has been carried out to establish the extent to which the inclusion of a source of unsaturated fatty acid (soyabean oil) in a more saturated fat (beef tallow) resulted in a synergistic relationship in terms of the usefulness of the resultant fat in feeding. In the evaluation of fat the importance of the greater sensitivity of digestibility measurements as opposed to growth records is emphasised. It has been shown that the inclusion of 5 per cent soyabean oil in a beef tallow preparation will increase the digestibility from around 75 per cent to 87 per cent. Values for the digestibility of various fats available for poultry feeding have been determined.  相似文献   

Fats and amino acids in broiler rations. 5. Energy-protein balance in starter rations     

C G Payne  D Lewis 《British poultry science》1966,7(3):199-207

An attempt has been made to establish, under the conditions prevailing in the United Kingdom, an optimum energy‐protein balance for broiler starter rations. It has been shown that either increasing the supply of protein or energy‐yielding nutrients in the starter diet can lead to an improvement in overall growth performance. It is suggested that such an advantage is more apparent with cocks than pullets and more likely to be observed with birds of high growth potential.

No particular merit could be shown for the use of sesame meal supplemented with lysine as the sole source of protein‐rich material.  相似文献   

Attraction of male Rhipicephalus appendiculatus ticks to females in relation to feeding     

M.G. Leahy  R. Galun  R.E. Purnell  R.C. Payne 《Veterinary parasitology》1976,1(3):249-256

Five experiments were carried out on the movement of partially fed male Rhipicephalus appendiculatus ticks on rabbits towards other ticks of the same species. Male ticks pre-fed for 5 days were attracted towards pre-fed females, slightly attracted towards other pre-fed males, but not attracted towards nymphal ticks or recently relinquished feeding sites of adult or nymphal ticks. Female ticks fed for 5 days or longer were particularly attractive to male ticks which had also fed for 5 days or longer. Eight-week-old female ticks were most attractive to males, and 8-week-old male ticks most attracted to females. It is suggested that the male ticks may be attracted to the females by means of a sex pheromone, as has been shown in other ixodid tick species.  相似文献

The influence of graded levels of atmospheric ammonia on chickens     

D. R. Charles  C. G. Payne 《British poultry science》1966,7(3):189-198

Studies have been carried out to ascertain the effects of ammonia on the performance of White Leghorn hens housed in various environments of defined temperature and humidity. At 18° C. and 67 per cent relative humidity, the use of atmospheres containing 105 p.p.m. of ammonia by volume, significantly reduced egg production after 10 weeks’ exposure. No effects were observed on egg quality. However voluntary food intake was reduced in ammoniated atmospheres and live‐weight gain was lower. No recovery in production occurred when the treated groups were maintained for a further 12 weeks in an atmosphere free of ammonia.

When White Leghorn hens were housed at an environmental temperature of 28° C., body weight declined. The decrease in live‐weight was greatest at the high ammonia concentration of 102 p.p.m., and was significant after only 1 week's exposure to ammonia. Food intake of the controls was approximately 25 per cent lower at 28° C. than at 18° C., whilst 100 p.p.m. of ammonia further reduced food intake by more than 10 per cent. In one experiment at 28° C., egg production was significantly reduced after 7 weeks' exposure to ammonia.

In a subsequent trial, a high protein, vitamin and mineral diet prevented the onset of any deleterious effects of ammonia on egg production, even though food consumption fell to 75 g./bird/day at 29° C., 43 per cent relative humidity and 104 p.p.m. of ammonia. When a diet low in energy level was fed to hens subjected to high concentrations of ammonia, their voluntary food intake did not increase, and their production deteriorated rapidly.  相似文献
