Ação anti-helmíntica de jurubeba e batata de purga adicionadas à dieta de ovelhas prenhas e não prenhas.

Abstract

The use of botanical species that present effective secondary metabolites for the parasitosis control has been studied to replace chemical products and to decrease the resistance. There is a growing demand by Alternative Medicine, Phytotherapy, because of the low cost, low toxicity and do not present residues in the animal products. There are many studies on treatment of animals with plants, especially the anthelmintics. The objective of this wok was to evaluate the effect of the different levels of concentrate and of the anthelmintic activity of the bran root of Solanum paniculatum L. (Jurubeba) and Operculina hamiltonii (G. Don) D. F. Austin & Staples (Batata de purga) on the parasitism of Santa Inês ewes, confined, naturally infected, on the peripartum. Il was used 24 ewes, being 12 pregnant and 12 nonpregnant, divided into groups: control (Albendazole 5%), treated with Jurubeba and treated with Jurubeba plus Batata de purga. The experimental diets were distributed into two levels of concentrate: 1% and 1.5%. The reduction of the number of fecal eggs was evaluated by Gordon and Whitlock (1939) technique and the larval culture, by Roberts and O’Sullivan (1950) technique. It was performed biochemical dosages in order to determinate serum parameters in relation to the parasitism. The animals were distributed into a factorial arrangement 3x2x2 (anthelmintic treatment, reproductive phase, concentrate levels) design. Results were submitted to the analysis of variance and test of Tukey 5% significance (SAS, 2003). Treatment with Jurubeba in natura signals as an alternative to the control of gastrintestinal helmintiasis, mainly in non-pregnant ewes who have presented clinically healthy states, even with a high degree of parasitism, especially in ewe who received 1.5% of concentrate, being possible to replace the Albendazole. However, the administration of Jurubeba bran plus Batata de purga is not effective to the control of gastrintestinal helmintiasis of pregnant or non-pregnant Santa Inês ewes naturally infected and raised on intensive system in semi-arid of Paraiba Estate. Through the results of phytochemistry analyses carried out in this work, it is noted that the studied species have compounds that belong to the alkaloids and tannins classes, which can be potentially activated in biological and pharmacological models. Treatment with the jurubeba bran root has high contend of condensed tannins and signals as an alternative control of gastrintestinal helminthiasis of nonpregnant ewes. Animals that have received differentiated nutritional with higher levels of nutrients become resilient to parasitism. Providing JU and JB maintained the nutritional status regardless of the parasite load. The specimens of jurubeba and batata de purga were not considered toxic to the ewe in peripartum.
