Ocorrência de microrganismos em ração animal preparada artesanalmente a partir do licuri (Syagrus coronata)

During the dry season in the Brazilian Caatinga region when sources of food are very scanty, many farmers use alternative forms to feed their livestock. One of these alternative forms is the feed made with the fruits of licuri palm (Syagrus coronata), produced by hand by farmers or associations without any microbial control, until the present study. The control of the microbial growth in feeds, used in the animal feeding, aims mainly to decrease risks in the health of the meat consumers, by increasing sanitation and hygienic quality of the feed. Therefore, this work aimed to carry out a microbiological analysis (presence of salmonela, counting of mesophilic microorganisms, and contamination by filamentous fungi and yeasts) of the ration of licuri prepared by an association of agricultural producers from the town of Valente, Bahia. The microbiological quality in the analyzed samples was good in accordance with standardized microbiological norms from The Netherlands, without salmonela, low counting of mesophilic microorganisms, and low contamination by filamentous fungi and yeasts in all analyses that were conducted. This is the first work published that describes the microbiological quality of the licuri feed produced by hand.Durante a época de seca na região da Caatinga brasileira, quando a oferta de alimento é escassa, muitos produtores utilizam formas alternativas para alimentar seu rebanho. Uma delas é a ração à base de frutos de licurizeiro (Syagrus coronata), processada artesanalmente pelos próprios produtores rurais ou associações, sem nenhum controle microbiano, feito até o presente estudo. O controle do desenvolvimento microbiano em rações utilizadas na alimentação animal visa principalmente diminuir os riscos à saúde dos consumidores de carnes, melhorando a qualidade higiênica e sanitária da ração. Por isso, este trabalho objetivou a análise microbiológica (presença de salmonelas, contagem de microsganismos mesófilos e contaminação por fungos e leveduras) da ração à base de licuri preparada por uma associação de produtores rurais do município de Valente, Bahia. A qualidade microbiológica encontrada nas amostras analisadas foi boa quando comparada com as normas microbiológicas para ração padronizadas da Holanda, ocorrendo ausência de salmonelas, baixa contagem de microrganismos mesófilos e baixa contaminação por fungos filamentosos e leveduras em todas as análises realizadas. Este é o primeiro trabalho na literatura que descreve a qualidade microbiológica da ração à base de licuri produzida artesanalmente

Interaction Between Cortical Auditory Processing and Vagal Regulation of Heart Rate in Language Tasks: A Randomized, Prospective, Observational, Analytical and Cross-Sectional Study

Cortical auditory evoked potentials (CAEP) throughout a language task is beneficial during psychophysiological evaluation to advance identification of language disorders. So as to better comprehend human communication and to provide additional elements for neuropsychological examinations we aimed to (1) examine the influence of language tasks on cortical auditory processing and vagal control of heart rate and (2) to verify a possible association between the parasympathetic cardiac regulation and cortical auditory processing in language tasks. This study was completed with 49 women. The subjects were separated into two groups: (1) phonological language tasks (N = 21) and (2) semantic (N = 21) language tasks. Heart rate variability (HRV) and CAEP were evaluated before and after the tests. HRV reduced (small effect size) and P3 wave latency increased after the phonological task. Identical variables were significantly correlated after the phonological task and linear regression indicated significant interaction between pNN50 (percentage of adjacent RR intervals with a difference of duration greater than 50 milliseconds) and P3 latency (16.9%). In conclusion, phonological language tasks slightly reduced parasympathetic control of HR and increased cognitive effort. The association between HRV and CAEP are anticipated to be involved in this mechanism
