Birth Weight, Neonatal Mortality and Transition Period in Kintamani Puppy Dog Development

The observations study was performed on a total of 72 puppies born alive from 16 pregnancy bitches at Asubali breeding kennel, Gianyar, Bali. After whelping, the total number of puppies born alive or dead within a litter, beginning the eyes open and first respond to hear was recorded. Each puppy was identified by a colored collar. Puppies were weighed at birth and continued until 7 day of age. Data were analyzed and presented as means and standard deviation. The difference of sex was analyzed using A two-tailed student t-test. The result of this study showed that average weight of the male puppies was 362.77±60.15 gram and the female puppies were 340.44±36.48 gram. During the first week of life, the mortality rate was 9.72%. The puppy’s eyes open at an age 10 to 15 day and begins to hear at an age 19 to 23 days. Birth weight and neonatal mortality was significantly affected by sex. Its concluded that the mortality rate neonatal was low in Kintamani dog.

Detection of Canine herpesvirus 1 in the breeding kennel and farm dogs by Real-time PCR

Background: Canine herpesvirus 1 (CHV-1) is known as a causal agent of death in newborn puppies and fertility problems in adults with a widespread distribution. There has been an increasing concern among dog breeders in Iran regarding CHV-1. This study is the first molecular detection of CHV-1 in breeding kennels and farm dogs in Iran using real-time PCR and investigation of various predisposing factors. Results: A total of 63 vaginal samples collected from 47 breeding kennels and 16 farm dogs were evaluated. In general, 21 out of 63 (33.3%) of vaginal samples were CHV-1-positive. The percentage of infection was higher in farm dogs, which was statistically significant. There was no significant association regarding other probable predisposing factors, including age, breed, pregnancy, and reproductive disorders. Conclusions: Considering the results of this study, CHV-1 is common in farm and breeding kennels and could pose a threat. Further studies are required to better understanding the distribution of the virus within Iran to advise dog breeders to more appropriate measures for management of CHV-1.

How experiments age: Gerontology, beagles, and species projection at Davis

Cold War curiosities about the dangers of radiation generated significant funding for an array of biomedical projects as enticing as they were unpredictable, introducing newly standardized experimental animals into laboratories and a novel merging of scientific disciplines. The desire to understand radiation’s effects on human longevity spurred a multi-sited, multi-decade project that subjected beagle dogs to varying degrees of irradiation. One of those laboratories, located at the southern tip of the campus of the University of California, Davis, eventually hosted an elaborate experimental breeding kennel and a population of ‘control’ dogs that set new milestones for canine longevity. The present article examines this gerontological spin-off experiment, using the study of aging as a method and object in order to analyze the emergence and disappearance of the Davis Radiobiology Laboratory and explore how research using new canine model organisms mirrored the politics and anxieties faced by citizens and scientists of the era, here termed ‘species projection’.
