Abstract
Nutritional requirements of lactating goats are high and require utilization of mixed rations including hay and concentrates. For measuring nutritive value of such rations, it is necessary to use metabolism cages adapted to the behavior of the goat, its physiological state and the administration of 2 kinds of feed. The system consists of a superelevated double cage with 2 feeding systems in which the goats are unconstrained, providing a satisfactory separation and collection of urine and feces without contamination by feeds. The behavior of the animals is not disturbed. The system was used for 2 yr during 3 consecutive mo. in 6 Alpine goats fed mixed rations of hay and concentrates.
