Swine Biological Values

Laboratory Swine

Care and Feeding
Experimental Conditions	Space dimensions vary with each experiment according to animal size and management program. Refer to NRC guidelines.*

Feeding Recommendations	Daily Feed Usage			Water Requirement	Begin Dry Food Consumption
	Approx. 2-3% of body weight, but varies with phase of life cycle (see specific product for other details).			Ad libitum	12-16 days

Environmental Data	Room Temp.	Humidity	Light	Litter Material
	Ambient conditions 10-25 °C	45-55%	8-14 hrs/day	As needed, straw, hay, shavings ground cobs, paper beddings. Avoid shredded newspapers.
