These animals (rats and C57B1/6 mice) were housed in groups of three per cage, under controlled conditions of light (12 h light/dark cycles), temperature (22 ± 3 °C) with free access to food and water.
They were housed five per cage under artificial conditions of light (light/dark cycle, light on at 7 00 a.m ., temperature (24°C), and humidity (45%) with food and water available ad libitum.
They were given free access to food and water and were housed 2 4 in each cage, with 12 h of light and 12 h of darkness.
Mice were housed up to 10 animals per cage under standard conditions of light and temperature and fed with standard laboratory chow ad libitum.
Female rats of the Wistar strain were housed in group cages under controlled conditions of light (12 h light, 12 h dark) and temperature (23 25°C).
A light cage of brass covered the blades, to protect them; it wasn't designed to protect people, and fan-related injuries were common.
Animals were housed collectively in plastic cages, maintained under standard conditions of light, ventilation, temperature, and humidity, and allowed free access to the standard pellet diet and tap water.
One-week-old chickens were housed in individual cages, and kept on 16 h of light and 8 h of dark with feed and water provided ad libitum.
The Science Museum, a 150-foot-high white structure of steel, reinforced concrete and glass, suggests something of the rib cage of a beached whale, with light pouring into its main exhibition area on the third floor, itself so spacious as to remind one of a hangar (and a plane is in fact on display there).
