Efeito da aplicação de biocarvão, cama de frango e formulado NPK no estado nutricional de laranjeira em Terra Mulata

Growing in orange on Terra Mulata has been submitted nutrient limitation requiring correction in agricultural areas. The application of biochar associated with another source of nutrients can be a viable alternative to increase the efficiency of fertilizers and reduce losses in the areas. The objective of this study was to evaluate the effect of biochar, poultry litter and NPK in the nutritional status of orange trees grown in an Oxisol with anthropogenic A horizon (Terra Mulata). The study was conducted in a rural property landfall in Manacapuru (AM) in a randomized block design with eight treatments using biochar, poultry litter and NPK (4-14-8) applied in isolation and associates. To review two samples were taken at different periods of sheets to determine the nutritional status. Fertilizers applied did not increase the efficiency in the availability of contents of N, P, Fe and Zn, being the latter below the range of suitable content. As for the K, compost chicken manure and their combinations increased their availability, and the highest levels of Mg were found in the control treatment.

Otimização de método para determinação de antimicrobianos em cama de frango por clae-flu

O extraordinário desenvolvimento da produção avícola, particularmente no setor de frango de corte, tornou o Brasil um importante produtor e exportador de carne de frango. Esse fato aliado a proibição da utilização de cama de frango como ração para ruminantes pela Instrução Normativa nº15 de 17 de julho de 2001, fez com que este resíduo se tornasse um problema ecológico e de saúde pública de alta relevância, tanto pelo volume de resíduos gerado, quanto pela composição do mesmo, que pode conter diversos fármacos utilizados neste tipo de manejo, além de uréia, que após a oxidação natural no ambiente, resulta em nitrato que tem alto poder de contaminação de mananciais hídricos, principalmente subterrâneos. Dentre as substâncias que podem estar presentes na cama de frango, estão os antimicrobianos, utilizados como promotores de crescimento das aves. No Brasil, são pouquíssimos os trabalhos dedicados a investigar a ocorrência e o impacto ambiental de antimicrobianos. Desta maneira, este trabalho teve como objetivo otimizar e validar método para análise de três fluoroquinolonas (ciprofloxacina, norfloxacina e enrofloxacina) em cama de frango. O método estudado baseou-se em trabalhos da literatura em que moléculas similares foram analisadas em diversas matrizes, compreendendo a extração em ultrassom com acetonitrila acidificada com ácido acético (3% v/v) e análise por CLAE-FLU, modo isocrático com a fase móvel composta por 0,02 M H3PO4:ACN (83:17, v/v). Foram avaliados os parâmetros cromatográficos quanto à resolução, eficiência, linearidade e limites de detecção e quantif-1 para os três analitos. O tempo de análise do método cromatográfico otimizado é de 7,5 minutos. Avaliou-se também o efeito de matriz que foi significativo para norfloxacina e ciprofloxacina, correspondendo a 16 e 20%, respectivamente. Para a enrofloxacina a amostra...

Avaliação microbiológica da superfície muscular de carcaças ovinas durante as operações de abate em matadouro

In order to evaluate the hygienic-sanitary conditions of lamb carcasses for human consumption, this study aimed at quantifying populations of indicator microorganisms, such as: mesophiles and psychrotrophs, molds and yeasts, Escherichia coli, Staphylococcus spp. and at identifying pathogenic microorganisms (Salmonella sp. and Listeria spp.). The study was conducted in one lamb slaughterhouse located in the State of São Paulo. Swab samples were collected from muscle surface of forequarter and hindquarter regions of 30 half-carcasses after skinning, evisceration and washing processes. Population counts were between the following values in log10: 2,00 ± 0,32 and 2,59 ± 0,76 UFC/cm2 for mesophiles; 1,52 ± 0,98 and 2,35 ± 1,17 UFC/cm2 for psychrotrophs; 0,75 ± 0,87 and 1,23 ± 0,97 UFC/cm2 for molds and yeasts; 0,00 ± 0,00 and 0,31 ± 0,84 NMP/cm2 for Escherichia coli and 1,75 ± 0,71 and 1,95 ± 0,68 UFC/cm2 for Staphylococcus spp. Salmonella sp. and Listeria spp. were not detected from any of the sampled points. These results indicate the necessity to improve the hygienic-sanitary conditions.

O emprego de okara no processamento de hambúrger de frango fermentado com Lactobacillus acidophilus CRL 1014

Okara is a residue of production process of soy milk, wich has a considered nutritional value for containing proteins, lipids and fi bers in signifi cant amount, besides bioactive compounds, such as isofl avone. Despite these qualities, the great amount of okara produced annually in Brazil and in other countries generates a problem of disposal waste and it has served only for animal food products. Such situation can be changed by studies, that demonstrate the viability of okara’s utilization in human nourishment. Thus, the purpose of this research was to develop a fermented hamburger with a probiotic bacteria, based on chicken meat and okara fl our. Five formulations were processed: F1-100% of chicken meat, unfermented and containing curing salts, F2-100% of chicken meat, fermented with L. acidophilus, F3 - 90% of chicken meat and 10% of okara meal, fermented with L. acidophilus, F4 - 70% of chicken meat and 30% of okara meal, fermented with L. acidophilus; F5 - 50% of chicken meat and 50% of okara meal, fermented with L. acidophilus. All formulations were evaluated for the viability of the probiotic culture, determination of cooking yield and shrinkage percentage, pH and sensory characteristics. The results have demonstrated that it is possible to elaborate a chicken hamburger, fermented with Lactobacillus acidophilus CRL 1014, with the addition of 10% okara fl our.

Susceptibilidade antimicrobiana de amostras de escherichia coli isoladas de frango industrial (gallus gallus domesticus - linnaeus, 1758) com colibacilose

The present study evaluated the susceptibility of Escherichia coli samples isolated from poultry with colisepticemia in midwestern São Paulo State at the Ornitopathology Laboratory of FMVZ-UNESP/Botucatu, SP. A large number of samples were found that were multi-resistant to the antibiotics tested, the less effective drugs being sulfonamide and tetracycline. All samples were susceptible to norfloxacin and gentamicin.

Análise Energética do processo experimental de produção de Biodiesel a partir do óleo de frango

There is a great global concern about the depletion and the high cost of fossil fuel reserves exploitation, more than ever, it is necessary to make a profound study and take advantage of alternative sources that can be used as energy efficiency with an appropriate pricing and low environmental impact. Brazil, which has highlighted using alternative energy sources as the use of ethanol and, in recent years, has been encouraging the expansion of its energy matrix in which the biodiesel will have a strategic importance within the agrobusiness area. Biodiesel is a fuel that can replace the diesel, which is a petroleum derivative. It is an ester, produced in the transesterification reaction of vegetable oils and animal greases, in an alcohol with an additional catalyst, are converted into fatty acids and result in esters with glycerol as sub products. The objective of this study was to estimate the final energy balance for the process biodiesel production from oil chicken waste. The energy balance estimation was quantified in calorific value according to the energy expenditure by calorimetric bomb method. The relationship between input and output of energy was around 0.97. In a first evaluation, the procedures adopted should be improved enough, so the process can become energetic and economically viable.
