Última Traceability of animal protein byproducts in ruminants by multivariate analysis of isotope ratio mass spectrometry to prevent transmission of prion diseases J. Venom. Anim. Toxins incl. Trop. Dis. Ferreira Jr.,Rui Seabra; Silva,Daniela Alessandra Fossato da; Biscola,Natália Perussi; Sartori,Maria Márcia Pereira; Denadai,Juliana Célia; Jorge,André Mendes; Santos,Lucilene Delazari dos; Barraviera,Benedito. Abstract Background: Ruminant feed containing animal byproduct proteins (ABPs) is prohibited in many countries due to its risk of transmitting prion diseases (PD). In most cases the entire herd is sacrificed, which causes great harm to the producer countries by preventing their exportation of ruminant derived-products. Methods: We used stable isotope ratio mass spectrometry (IRMS) of carbon (13C/12C) and nitrogen (15N/14N) to trace the animal protein in the blood of 15 buffaloes (Bubalus bubalis) divided into three experimental groups: 1 - received only vegetable protein (VP) during 117 days; 2 - received animal and vegetable protein (AVP); and 3 - received animal and vegetable protein with animal protein subsequently removed (AVPR). Groups 2 and 3... Tipo: Info:eu-repo/semantics/article Palavras-chave: Prion diseases; Monitoring; Bovine spongiform; Encephalopathy; Stable isotopes.

Trop. Dis. Martinez,Melissa Gaste; Ducatti,Carlos; Silva,Evandro Tadeu; Sant’Anna,Savio Stefanini; Sartori,Maria Márcia Pereira; Barraviera,Benedito. Background Environmental devastation threatens the survival of many species, including venomous snakes such as the South American rattlesnake Crotalus durissus terrificus. This observation is based on the decrease of snakes collected and donated to Brazilian research institutes. Nevertheless, some individuals have managed to survive and procreate. The question is how these snakes are adapting in these new environmental conditions.Methods To answer it, the carbon-13 level of rattlesnakes and their feed (either laboratory or wild mice) was evaluated by isotope-ratio mass spectrometry. Thus, rattle segments from 16 adults and 15 offspring of captive snakes, and of three wild newborn C. d. terrificus were evaluated as well as 17 Mus musculus mice captured in...

Abstract: The objective of this work was to evaluate the diet components - crude fiber, neutral detergent fiber, acid detergent fiber, hemicellulose, cellulose, and lignin - as internal indicators in the determination of the apparent digestibility coefficients of dry matter, gross energy, and of the nutrients - crude protein, phosphorus, and amino acids - in Nile tilapia (Oreochromis niloticus). Groups of ten juveniles (80.3±1 g) were randomly distributed in six tanks of 250 L and fed two practical diets, either of a plant-origin diet or of a plant- and animal-origin diet. Both diets were supplemented with 0.1% chromium (III) oxide (Cr2O3). Faeces were collected by the modified Guelph system. The apparent digestibility coefficients were determined by the...

ABSTRACT: Industrialized coconut water may have been adulterated by adding sugar above the limit permitted by law. According to Brazilian law, industrialized coconut water can receive the maximum addition of 1 g of sugar per 100 mL of the drink. This work aimed to detect adulteration in industrialized coconut water produced in Brazil and measure the relative isotopic enrichment in fresh coconut water, using the techniques of stable isotopes of carbon. Fresh coconut water samples from 13 locations, industrialized coconut water samples of 17 different brands and cane sugar were analyzed by Isotope Ratio Mass Spectrometer coupled to an elemental analyzer. The relative isotopic enrichment found for fresh coconut water samples ranged from −26.40 to −23.76. From...

ABSTRACT The present study aimed to verify whether the inclusion of other ingredients in the diet of laying hens could interfere with the traceability of bovine meat and bone meal (BMBM) in eggs through stable carbon and nitrogen isotope analysis. Two hundred and fifty-six white laying hens were used and randomly distributed into eight treatments composed of: CONTROL: control diet; GLUTEN: control diet + corn gluten; YEAST: control diet + yeast; GLUTEN + YEAST: control diet + corn gluten + yeast; BMBM: control diet + 4.5 % BMBM; BMBM + GLUTEN: control diet + corn gluten + 4.5 % BMBM; BMBM + YEAST: control diet + yeast + 4.5 % BMBM; BMBM + GLUTEN + YEAST: control diet + corn gluten + yeast + 4.5 % BMBM. The isotopic results were subjected to multivariate... Tipo: Info:eu-repo/semantics/article Palavras-chave: Albumen; Carbon-13; Nitrogen-15; Traceability; Yolk.

The fact that Brazil is the world's largest sugarcane (Saccharum spp.) producer, leads to a great concern about the cropping systems used, since the most common practice involves manual harvesting prior to straw burning. Brazilian authorities approved a law prohibiting the burning practice of crop residues prior to harvest. However mechanized harvest creates the new problem of how to deal with the residues. Many studies have proposed the use of these residues as an energy source. The major difficulty in its use is how to economically transport sugarcane harvested biomass from the farm to a processing center. The aim of this work was to develop a model to optimize plant variety selection, minimize the cost of the residual biomass transfer process, to...

O palhiço derivado da colheita de cana-de-açúcar crua, com a redução gradativa das queimadas nos canaviais, tornou-se foco para os pesquisadores e produtores. As vantagens no recolhimento, na recuperação e no aproveitamento têm mobilizado pesquisadores de universidades, gerentes e diretores de usinas, interessados em encontrar a maneira mais produtiva, econômica e eficaz de realizar esse processo. O recolhimento do palhiço é feito em quatro estágios: primeiro o palhiço é enleirado, depois passado por uma máquina de compactação, posteriormente, acondicionado no caminhão e, finalmente, transportado para o centro de processamento. O estudo da viabilidade de aproveitamento desse resíduo para a geração de energia pode ser feito com base no custo e no balanço de...

No Brasil, a biomassa residual do cultivo de cana-de-açúcar é representada por folhas, palhas, ponteiros e frações de colmo que somam uma produção aproximada de 108 milhões de toneladas por ano; quantidade que permitiria a produção de 10,2 MWh de energia. Existem muitas cultivares como opção de plantio resultantes de programas de melhoramento visando à resistência a pragas, a doenças e à adaptação ao tipo de solo, cuja escolha é feita em virtude da produtividade física, bem como da produção de sacarose. Essa seleção pode ser auxiliada por modelos de otimização, visando minimizar a quantidade de resíduo de colheita, com ou sem imposições sobre a quantidade de energia obtida da biomassa. Pode, também, ser auxiliada pela maximização da quantidade de energia... Tipo: Info:eu-repo/semantics/article Palavras-chave: Resíduo de colheita; Otimização; Cana-de-açúcar.
