Resumo: |
Ionophores are antibiotic growth promoters and are commonly used in ruminant feed. These antibiotics belong to the group of additives that exercise improved animal performance controlling ruminal populations. In order to improve the fermentation efficiency, the ionophore operates in bacteria that have inefficient fermentation processes or harmful to animal performance. However, even representing a breakthrough in animal growth performance and mitigate the resulting methane ruminal fermentation, growth promoters are costly and condemned by consumer groups and institutions that prohibit the use of such products in order to prevent future toxicities in product end. In order to replace the use of synthetic additives, recent research with secondary compounds present in natural plant products are being made to mitigate methane, thus minimizing the cost of animal production free of methane production by rumen fermentation and possible toxicities in products finals. P. juliflora can be used as a natural additive since it presents inhibitory effects against some Gram-positive bacteria and even two species of Candida sp. Furthermore, P. juliflora may also have effectiveness in the manipulation of rumen fermentation. Thus it is necessary to further study the use of the feed control rumen digestion and fermentation. |
