Aversão alimentar condicionada em caprinos para controle da intoxicação por Ipomoea carnea.

Abstract

This work aims to test the technique of induction of conditioned aversion as a way of to avoid the ingestion and, therefore, the poisoning by Ipomoea carnea in goats. In the 1st day of the experiment, 6 animals received separately I. carnea leaves, the amount not consumed was weighed and 4 animals were treated with LiCl. The other two animals were not treated and served as control. The offering of the plant was repeated in the 2nd and 3rd days, the goats that ingested any amount of the plant were treated again with LiCi. To confirm the aversion all the animals were evaluated in 15 days. It was verified that in the second day of the experiment, two of the four animals did not consume the plant anymore, maintaining themselves in this way during the whole experimental period. In the third day only one animal ingested I. carnea, but on the 15th day the 4 experimental animals were averted. The control group maintained the consumption during the whole experimental period. The results obtained through this work revealed that the administration of LiCi provokes aversion to I. carnea in goats, and can be recommended as a control form of this plant poisoning in natural conditions.
