RESUMO

The objective of the study was to investigate the influence of anise seed (Pimpinella anisum L.) powder supplemented to the drinking water on selected blood parameters of broilers. In total, 360 one-day-old Hubbard Classic chicks were randomly divided into four groups with three replicates of 30 birds each. Anise seed powder was added at 0, 500, 750, and 1000mg/L to the drinking water offered to the C (control), T1, T2, and T3 groups respectively. The supplement was supplied for 56 days. When broilers were 28 and 56 days old, blood samples were collected (30 birds per group) by brachial vein puncture to evaluate the cellular components of blood (RBC, WBC, Hgb, HCT, H/L). The following serum biochemical parameters were evaluated: CHOL, GLU, TP, albumin, globulins, Ca, P, TG, total lipids, UA, and creatinine, as well as AST and ALT enzyme activities. The statistical analysis indicated that the anise supplement significantly improved blood RBC, WBC, Hgb, HCT, TP, albumin, globulin, GLU, P, and Ca levels of broilers in groups T4, T3, and T2 compared with the control group on days 28 and 56, and on average. Also, T3, T2 and T1 presented lower H/L ratio and CHOL, TG, total lipids, creatinine, UA, AST and ALT serum levels compared with the control group. The highest inclusion levels of anise seed powder, i.e., 1000 and 750mg/L, had a stimulating effect on the physiological traits of the birds.(AU)

RESUMO

Foeniculum vulgare Mill. é espécie herbácea da família Umbelliferae, nativa da região do Mediterrâneo e da Ásia Menor, amplamente distribuída em todo o território brasileiro. É conhecida popularmente como funcho ou erva-doce e usada na medicina como analgésico, digestivo, carminativo, diurético, expectorante, lactígeno, anti-inflamatório, e antiespasmódico. O extrato bruto etanólico para a verificação das atividades biológicas foi preparado a partir de sementes compradas no comércio. Para a realização do perfil fitoquímico foi utilizada a cromatografia em camada delgada analítica; a atividade antimicrobiana foi determinada pelo teste de difusão em disco de papel e da concentração inibitória mínima (CIM); a atividade antinociceptiva foi realizada pelo método de contorções abdominais em cobaias. Os micro-organismos testados foram isolados clínicos multirresistentes obtidos do Setor de Bacteriologia do Hospital das Clínicas de Pernambuco. O estudo fitoquímico identificou a maioria dos compostos secundários presentes na fração metanólica das sementes, sendo eles: triterpenos, glicosídeos de flavanóides, terpenos menores (monoterpenóides, sesquiterpenóide e diterpenóides), e açúcares redutores. Os resultados obtidos mostraram que o extrato etanólico apresentou maior atividade frente à Micrococcus spp. (CIM=250µg/mL). Os resultados da avaliação da atividade antinociceptiva demonstraram que apenas a dosagem de 298 mg/Kg quando comparado com o padrão indometacina conseguiu uma redução significativa no número de contorções abdominais dos animais. Estudos posteriores deverão ser realizados para a identificação e isolamento de alguns compostos secundários, bem como a realização de outros protocolos de analgesia.

Foeniculum vulgare Mill. (Umbelliferae) is a herbaceous plant of the family Umbelliferae, native to the Mediterranean and Asia Minor region and widely distributed all over the Brazilian territory. It is commonly known as fennel or "erva-doce" and has been used in medicine as analgesic, digestive, carminative, diuretic, expectorant, lactigenous, anti-inflammatory, and antispasmodic agent. Crude ethanolic extract for the verification of biological activities was prepared from seeds bought in the market. For the phytochemical profile, analytical thin-layer chromatography was used; the antimicrobial activity was determined by the paper disc diffusion test and minimum inhibitory concentration (MIC); the antinociceptive activity was verified by the method of abdominal writhings in the animals. The tested microorganisms were multiresistant clinical isolates obtained from the Bacteriology Sector of the Clinical Hospital of Pernambuco. The phytochemical study identified the majority of secondary compounds present in the methanolic fraction of seeds, as follows: triterpenes, flavanoid glycosides, smaller terpenes (monoterpenoids, sesquiterpenoids and diterpenoids) and reducing sugars. The obtained results showed that the ethanolic extract had greater activity against Micrococcus spp. (MIC=250µg/mL). Results of the evaluation of the antinociceptive activity demonstrated that only the dosage of 298 mg/Kg, compared to the indomethacin pattern, led to a significant reduction in the number of abdominal writhings in the animals. Further studies will be carried out for the identification and isolation of some secondary compounds, as well as other analgesic protocols.
