Abstract: This trial was conducted to evaluate the average daily intake of sorghum silage, sorghum silage with corn meal as additive and sorghum silage with Lacto Silo as additive. It was also evaluated the apparent digestibility in vivo and using the acid detergent lignin (ADL) as marker. Values of apparent digestibility of some nutritive components of these tree silages were correlated. Nine castrated lambs, without defined race, with initial average body weight of 30.7 Kg were used, distributed in tree treatments and two periods. The animals were placed in metabolic cages and the sorghum silage without additive provided higher intake of dry matter (DM), organic matter (OM), acid detergent fiber (ADF), neutral detergent fiber (NDF), total carbohydrates (TC) and hemicellulose (HEM). The apparent digestibility coefficient of the nutritive components did not differ when evaluated by the total feces collection. However, when using the LDA as marker there was significant difference to ADF, where the sorghum silage without additive was higher then sorghum silage with Lacto Silo. The sorghum silage with corn meal was similar to other two silages. There was significant correlation only to TC and HEM, between the two methodologies used to estimate.digestibility. Este trabalho teve como objetivos avaliar o consumo médio diário da silagem de sorgo, da silagem de sorgo aditivada com fubá e da silagem de sorgo aditivada com Lacto Silo., bem como estimar a digestibilidade aparente in vivo e pelo uso da lignina em detergente ácido (LDA) como indicador, e correlacionar os valores das digestibilidades aparentes de alguns componentes nutritivos destas três silagens. Foram utilizados nove ovinos machos, castrados, sem ra a definida, com peso médio inicial de 30,7 Kg, distribuídos em três tratamentos e dois períodos, alojados em gaiolas metabólicas. A silagem de sorgo sem aditivos proporcionou maiores níveis de consumo de matéria seca (MS), matéria organica (MO), fibra em detergente ácido (FDA), fibra em detergente neutro (FDN), carboidratos totais (CT) e hemicelulose (HEM). Os coeficientes de digestibilidade aparente dos componentes nutritivos das três silagens foram semelhantes quando avaliados pela coleta total de fezes. Já utilizando a LDA como indicador houve diferen a significativa apenas para a FDA, onde a silagem de sorgo sem aditivos foi superior a silagem de sorgo aditivada com Lacto Silo. A silagem de sorgo com fubá foi semelhante às duas. Houve correla o significativa apenas para CT e HEM entre as duas metodologias usadas para estimar as digestibilidades.

Abstract: the objective of this trial was to determine the intestinal digestibility of nutrients using an in vitro three-step enzymatic procedure. eight concentrate feeds were evaluated: whole sunflower (wsf), mechanically pressed sunflower cake (sfc1x; one press extraction), mechanically pressed sunflower cake (sfc2x; two press extractions), whole soybean (wsb), partially degreased soybean (dsb), soybean meal (sbm), degreased corn germ meal (cgm), and a commercial concentrate with 36% of cp (cc). feeds were incubated in the rumen of bovines for 33, 20 and 12 hours corresponding approximately to the rates of passage of 3, 5 and 8%/h, respectively. the ruminal undegradable residues were digested with a 1.9 ph-pepsin solution for one hour at 38oc followed by a second digestion with a 7.8 ph-pancreatin solution for 24 hours also at 38oc. the residues were then analyzed for total nitrogen, dry matter, and organic matter. the in vitro intestinal digestibilities of ruminal undegradable dm, protein, and organic matter assuming a rate of passage of 5%/h ranged from 7.88 to 37.72%, 13.67 to 81.76%, and 7.93 to 37.14%, respectively. commercial concentrate and wsb showed the greatest dry matter and organic matter digestibilities. crude protein digestibility was highest on cc and sbm and lowest on wsf. organic matter digestibility also was lowest on wsf. the lowest values of digestible ruminal undegradable protein (rupd) were observed on both sunflower cakes (sfc1x and sfc2x) suggesting that these feeds should not be used in diets of animals with high requirements of rupd.

Abstract: Thiosemicarbazones are a class of compounds known by their chemical and biological properties, such as antitumor, antibacterial, antiviral and antiprotozoal activity. Their ability to form chelates with metals has great importance in their biological activities. Their synthesis is very simple, versatile and clean, usually giving high yields. They are largely employed as intermediates, in the synthesis of others compounds. This article is a survey of some of these characteristics showing their great importance to organic and medicinal chemistry.

Abstract: Chlorpromazine and decocts of N. corniger were collected from two different plant species used in the traditional medicine were tested for their antimicrobial activity against strains of Escherichia coli resistant to aminoglycosides. The growth of two bacterial strains of E. coli was tested using decocts and chlorpromazine alone or associeted with aminogycosides.The MIC and MBC values were ≥1024 μg/ml for both strains of E. coli assayed. A significant synergism was observed between both decocts and chlorpromazine when assyed with neomycin. This synergism with neomycin indicates the involvement of an efflux system in the resistance to this aminoglycoside.Therefore it is suggested that natural products from N. corniger could be used as a source of zoo-derived natural products with modifying antibiotic activity to aminoglycosides, being a new weapon against the bacterial resistance to antibiotics.Although medicinal plants are well studied around the world, animals or animal parts have been broadly used in Brazilian traditional medicine and have played a significant role in healing practices [1,2]. Several species from Insecta have been used as remedies [1-4]. Among these species, the Neotropical termite Nasutitermes corniger is commonly used in traditional medicine in Northeast Brazil. N. corniger is distributed from southern Mexico to northern Argentina and the West Indies and is spread from the semi-arid to tropical rain forest ecosystems [5-9]. In South America, this species is highly adaptable to colonizing contrasting habitats in urban, agricultural, and natural environments [10,11]. N. corniger builds arboreal carton nests with a population that can exceed 400,000 individuals/nest, and density that ranges from 22.1 to 47.1 nest/ha in tropical rain forests [10,12,13]. Based on morphologic, genetic and biogeographic evidence, N. costalis has been revised as a synonym of N. corniger, like the congeneric species N. araujoi, N. globiceps and N. tatarendae which are al

Abstract: Data was obtained through field surveys conducted in the public markets in the city of Santa Cruz do Capibaribe, Pernambuco State, Brazil. We interviewed 16 merchants (9 men and 7 women) who provided information regarding folk remedies based on animal products.A total of 37 animal species (29 families), distributed among 7 taxonomic categories were found to be used to treat 51 different ailments. The most frequently cited treatments focused on the respiratory system, and were mainly related to problems with asthma. Zootherapeutic products are prescribed as single drugs or are mixed with other ingredients. Mixtures may include several to many more valuable medicinal animals added to other larger doses of more common medicinal animals and plants. The uses of certain medicinal animals are associated with popular local beliefs known as 'simpatias'. We identified 2 medicinal species (Struthio camelus and Nasutitermes macrocephalus) not previously documented for Brazil. The use of animals as remedies in the area surveyed is associated with socio economic and cultural factors. Some of the medicinal animal species encountered in this study are included in lists of endangered species.Our results demonstrate that a large variety of animals are used in traditional medicinal practices in Brazil's semi-arid northeastern region. In addition to the need for pharmacological investigations in order to confirm the efficiency of these folk medicines, the present study emphasizes the importance of establishing conservation priorities and sustainable production of the various medicinal animals used. The local fauna, folk culture, and monetary value of these activities are key factors influencing the use and commercialization of animal species for therapeutic purposes.Plants and animals have been used as medicinal sources since ancient times [1-4], and even today animal and plant-based pharmacopeias continue to play an essential role in world health care [5]. The use of biological resour
