Contribuição para o conhecimento de algumas leguminosas como forrageiras - Aceitação, palatabilidade e toxides - Testes em coelhos e cobaios

Abstract

Working with laboratory animals, the A. tested toxicity, palatability, consumption and efficiency of the following legumes : Mucuna pruriens, Wall, Styzolobium Deeringianum Steph & Cort, Indigofera hirsuta Lam. Tephrosia cândida, Cajanus cajan Millsp., Canavalia ensiformes DC, Clitoria ternatea L, Crotalaria juncea L., C. paulina, C. spectabilis Roth, C. striata DC C. brevijlora, C. campista, C. lanceolata and C. anagyroides. Guinea pigs were used to test toxicity and palatability of these Jegumes as forage, and yet, the same about the seeds of Crotalaria spectabilis, C. anagyroides and C. striata. The A. controlled the consumption by rabbits of ten kinds of these legumes (see Table I and II), to testify toxicity and acceptance of them. Crotalaria juncea reveals to be, the most palatable by the amount of material consumed, and gets the third place in efficiency. Canavalia ensijormes DC, notwithstanding in the fifth place in the amount of material consumed, was the most efficient. Some legumes revealed little palatability and only C. spetabilis, Roth, proved highly poisonous, killing animals during the test. The objective of this research is to detect legumes to be used as forage in tropical conditions.
