Husbandry Breeding Systems
Brother-syster selective mating system is used to maintain ICR Free hydronephrosis mouse in foundation stock. Environment The ICR hydronephrosis mouse is housed in the controlled environment. The ventilation, temperature and humidity are controlled by HVAC (Heating, Ventilating, Air conditioning) system. - Temperature range at about 24 ± 2 ํC - Relative humidity is ranged between 55 + 10% - Air changes per hour 10-15 ACH - Light: and dark cycle 12:12 hours - Mouse is sensitive to noise so the noise level should be < 85 db. Feed and water The Mlac:ICR is fed on the commercial diet (No. CP 082) product of Perfect companion group co. Ltd., the animal feed manufacturer which milled according to our requested specifications. Food is provided in stainless steel wire- bar lid feeders ad libitum. The RO Water is used for the drinking water which is chlorinated at a concentration of 10-12 ppm to make it free from Pseudomonas aeruginosa. The drinkingwater is provided in bottles with sipper tubes Bedding
Hard wood chips (or shaving) is used for mouse as bedding material. The same bedding is used in shipping containers. Dried bedding is packed in brown paper bags and sterilized by autoclave at 135 C for 7 minutes before used. The ICR Free hydronephrosis mouse used shoe box Cages by size as below

Experimental Uses The genetic background of this strain is similar to ICR Outbred mouse strain of our Center but they are totally free from hydronephrosis mutant gene. |
