Resumo

This research aimedto investigate the toxic action of Vitexgardneriana on microcrustacean Artemiasalina by using hydroalcoholic extract fromleaves (EHF) and acute toxicity test (CL50)concentrations of 100, 500, 1.000, 10.000,20.000, and 50.000/mL. Sodium hypochlorite(NaClO) at 1% was used as positive control,and saline and 1% DMSO were used asnegative control. Vitex gardneriana showedlow toxic potential, with 50% mortality inthe microcrustacean metanauplii population(concentration: 34.600 mg/mL). A. salina isa seawater microcrustacean widely used inbioassays for determining the toxic dose ofbioactive substances because of its low costsand its related simple, aseptic procedures. Todetermine the toxic action of the hydroalcoholicextract of V. Gardneriana on eggs and larvaeof Haemonchus contortus, 2,5mL of EHF witha concentration of 34,600 mg/mL were addedinto single-species nematode fecal culturescontaining approximately 12.000 eggs. Only26,6% of the eggs hatched, correspondingto an EHF efÀ ciency of 73,3%, whereas thehatchability was 50% in control, with 6.000larvae recovered. The À ndings show thepotential of this plant as an alternative inparasite control.

Resumo

This work had as objective to determine serum concentrations of proteins and minerals in lambs fed with Spirulina platensis-enriched milk. Thirty lambs were randomly distributed into blocks with plots subdivided into the time. Blood samples were collected fortnightly to determine the metabolic indicators. There was no interaction (P>0.05) between concentration of Spirulin and the period of administration concerning to the values of urea. However, for total proteins, it was observed interaction between concentration of Spirulina and experimental period. Total protein concentration has differed (P


Este trabalho teve como objetivo, determinar as concentrações séricas protéicas e minerais de cordeiros alimentados artificialmente com leite enriquecido com Spirulina platentensis. Trinta cordeiros foram distribuídos em delineamento em blocos ao acaso com parcelas subdivididas no tempo. Amostras sanguíneas foram coletadas, a cada 15 dias, para determinação de indicadores metabólicos. Não houve interação (P> 0,05) entre a concentração de espirulina e o período de administração para os valores médios de uréia. No entanto quanto às proteínas totais, observou-se interação entre a concentração de espirulina e o período experimental. A concentração de proteínas totais diferiu (P
