The Care and Breeding of Laboratory Animals
As biological research is increasingly concerned with the description of the reactions and adjustments of individuals to the more subtle environmental changes and chronic rather than acute states, there is a growing demand for healthy animals of known lineage-and the necessity for their maintenance under experimental circumstances in normal condition; a demand that arises at a time when a large...
متن کاملModern ways of feeding laboratory animals.
There is a trend in the feeding habits of biologists-that is, in the way they feed their animals, not themselves-going back some 20 or 30 years. It starts with the homely methods of pet-keeping: for mice, bread soaked in milk with a handful of oats and an occasional lettuce or dandelion leaf; through the preparation of sticky mashes of various kinds, with or without supplements; the offering of...
متن کاملFeeding and breeding aspects of Stomoxys calcitrans (Diptera: Muscidae) under laboratory conditions
Bionomic aspects of Stomoxys calcitrans (Linnaeus, 1758) (Diptera: Muscidae) were studied under laboratory conditions. For this reason, laboratory-rearing techniques were optimized at the National Veterinary School of Toulouse. The colony was maintained at 25±2°C, 50±10% RH under a 12-hour light cycle and observed daily. The size of each adult cage is 30x30x30 cm and designed to house about 500...
متن کاملStudy of zoonotic bacteria in conventional laboratory mice breeding colonies
To investigate the status of conventional laboratory mice colonies for zoonotic bacteria, three mice colonies, NIH, NMRI and Balb/c strains of Razi institute were studied for five zoonotic bacteria including Pasteurella pneumotropica, Salmonella typhimurium, Salmonella enteritidis, Streptobacillus moniliformis, Streptococcus Pneumonia. Study populations were 74 mice of premature, mature and pos...
متن کاملEffects of breeding density, feeding cycle, and light environment on the artificial culture of Poecilobdella manillensis
To provide a scientific basis for artificial culture, the effects of different breeding densities, feeding cycles, and light environments on the growth regulation of Poecilobdella manillensis were studied. After P. manillensis were cultured at breeding densities of 250 ~ 3250 leeches m-2; feeding cycles of 2 ~ 16 days; and a light environment with noise or a light-free environment without noise...
