Water

Autoclaved water is being used.
Water Contaminants checks:
Routine system checks include general observation of the overall system, the chemical and water storage tanks to assure the system is functioning properly.

A quarterly sample is collected to assess the Bio-Burden, free chlorine levels, Pseudomonas sp., and coliform organisms. The water is also evaluated for contaminant analysis yearly once.

Feed

Feed is provided Ad libitum, unless it depends upon the study protocol. sample are sent for nutritional analysis and contamination analysis.

  1. Type and source of food stuffs.
    • Global Rodent # 2018SC (Sterilizable), Harlan Netherland
    • Nutrilab ® Rodent - IR Diets (Irradiated), Provimi India
    • Nutrilab ® Rabbit - IR Diets (Irradiated), Provimi India
    • Nutrilab ® G. Pig - IR Diets (Irradiated), Provimi India

  2. Storage Place:
    Diets are stored in dedicated rooms of Vivo Biotech that are vermin proof and temperature controlled. Feed bags are stored off the floor, and stacked away from walls to allow for air circulation as well as pest control. A professional exterminator monitors pest control.

Bedding

Contact Bedding:
Corncob bedding material is used for rodents and G.Pig maintained in solid bottom cages. The bedding material is autoclaved before use.

Bedding# 7072 [CERTIFIED 118- PURELITE SANITIZED CORN COB (301bs)]

Bedding storage facilities:
Bedding material is stored off the floor, and stacked away from walls to allow for air circulation as well as pest control. A professional exterminator monitors pest control. Dedicated bedding material storage room is provided in Vivarium. Samples from one lot of contact bedding material each year to an outside laboratory to monitor for contaminants such as pesticides, bacteria, yeast, and molds. This analysis and the manufacturer’s analysis are reviewed and maintained on file.

Temperature and Humidity

Individual animal room temperature is controlled with an ambient temperature of 18-26°C.
Humidity throughout the building is controlled at 30-70% with general building thermo-hygrometer.

Man, Animals and Material Movement

The facility is a conventional facility where the movements is carried out from clean to dirty.

Cage washing

All cages are autoclaved before entering into the clean area. The washing process consists of four stages:

Stage 1 - Water wash – This stage consists of flushing water on the cages. All the solid waste attached to the cage gets cleaned.
Stage 2 – Detergent wash – A detergent solution is used and the cages are soaked for 15 minutes after which they are scrubbed with suitable scrubber, if required.
Stage 3 – Flushing - In this stage the cages are again cleaned under running water.
Stage 4 – Rinsing - In this stage the cages are rinsed with water and finally placed on pallets. These wash cages are later autoclaved before use.
