     Teaching an infant to self-feed and accurately measuring their intake is a problem all nurseries face. Many feeding bottles used today contain a steel tube and/or nipple that slopes downward into the cage. The bottle created by Ruppenthal and colleagues has an upward sloping steel tube with a pet nipple and an air tube, which opens into the air pocket to allow air to travel. This design allows fluid to flow back into the bottle when the animal stops sucking. The design results in increased accuracy when measuring intakes. Ventral support and a clinging surface must be offered to allow infants to reach the nipple to achieve self-feeding. A PVC pipe cut at an angle is placed in the cage and covered with soft cloth materials. The pipe has a hole in which the bottle nipple will protrude out above the cloth materials. The feeding bottle uses an elongated tube during this period that is able to reach through the cage and the training surrogate. Once animals are able to self-feed, the training surrogate is removed and a shorter tube, which only reaches through the cage, is used. The use of the bottle and the surrogate together allows animals to self-feed at a median age of 13 days.
