Rastreability of bovine meat and bone meal using the stable isotope technique i...
Denadai,Juliana Célia; Batistioli,Julianna Santos; Sartori,José Roberto; Madeira,Luciene Aparecida; Sartori,Maria Márcia PereiraABSTRACT 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 g...
Interactive effects of digestible protein levels on thermal and physical stress...
Freitas,Jakeline Marcela Azambuja de; Peres,Helena; Carvalho,Pedro Luiz Pucci Figueiredo de; Furuya,Wilson Massamitu; Sartori,Maria Márcia PereiraABSTRACT The effects of dietary digestible protein (DP) levels (22, 26, 29, 32, and 34%) and different stressors (cold-induced stress, CIS; heat/dissolved oxygen-induced stress, HDOIS; transport-induced stress, TIS; and size-sorting-induced stress, SSIS) on hemato-biochemical parameters were evaluated. Four hundred and forty Nile tilapia fingerlings were distributed into 40-250 L aquaria and fed experimental di...
Interactive key (Lucid) for identification of fungi in vegetable seeds
Pierozzi,Caroline Geraldi; Fujihara,Ricardo Toshio; Souza,Efrain de Santana; Pizetta,Marília; Sartori,Maria Márcia Pereira; Kronka,Adriana ZaninABSTRACT Interactive keys are tools that aid research and technical work since identification of organisms has become increasingly present in the scientific and academic context. An interactive key was developed with the software Lucid v. 3.3 for the identification of eleven fungal species associated with onion, carrot, pepper and tomato seeds. It was based on a matrix composed of six features: crop, conidium, ...
Identification of the production system of beef cattle by the stable isotope an...
Perdigão,Alexandre; Martins,Cyntia Ludovico; Vieira Junior,Luiz Carlos; Sartori,Maria Márcia Pereira; Niehues,Maria Betânia; Arrigoni,Mário De BeniAbstract: The objective of this work was to evaluate the potential of the stable isotope technique to characterize beef cattle production systems in tropical conditions. For this, carbon and nitrogen stable isotopes were identified in non-defatted and defatted bovine muscles. A total of 45 cattle were evaluated in three production systems: pasture, conventional feedlot, and young beef bull feedlot (n = 15 per s...
Traceability of animal meals in quail eggs using carbon and nitrogen stable iso...
Ishizuka,Adriele Nayara Dias; Carvalho,Marco Antônio Gonzales de; Araujo,Robert Guaracy Aparecido Cardoso; Denadai,Juliana CéliaAbstract: The objective of this work was to detect the inclusion of animal meal in Japanese quail (Coturnix coturnix japonica) diets, by analyzing eggs and their fractions (albumen and yolk) through the technique of carbon (13C/12C) and nitrogen (15N/14N) stable isotopes. Four hundred and thirty-two Japanese quails, 45-day-old females, were distributed in a completely randomized experimental design, in eight tr...
Productive potential and castor bean selection of the FCA-PB cultivar progenies
Silva,Jackson da; Ramos,Andréia Rodrigues; Amorim,Deoclécio Jardim; Zanotto,Mauricio Dutra; Sartori,Maria Márcia PereiraABSTRACT Castor bean is a very important crop, however, in Brazil it still has relatively low productivity, 0.47 Mg ha-1 as a mean. Besides that the Country has significant castor oil demand and depends on international commerce to complement its production. The solution of these problems goes through the development of genotypes highly productive and adapted to the producing regions. So, the objective of this ...
Use of stable isotopes of carbon to detect coconut water adulteration
Imaizumi,Vitor Massami; Sartori,Maria Márcia Pereira; Ducatti,Carlos; Venturini Filho,Waldemar GastoniABSTRACT: 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...
Traceability of animal protein byproducts in ruminants by multivariate analysis...
Ferreira Jr.,Rui Seabra; Silva,Daniela Alessandra Fossato da; Biscola,Natália Perussi; Sartori,Maria Márcia Pereira; Denadai,Juliana CéliaAbstract 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 nitrog...
Morphological characterization and selection of castor bean accessions for mech...
Oliveira Neto,Sebastião Soares de; Manjavachi,Matheus Kainan de Paula; Zeffa,Douglas Mariani; Sartori,Maria Márcia Pereira; Zanotto,Maurício DutraABSTRACT Castor bean (Ricinus communis L.) is an oilseed found in different regions worldwide, due to its easy propagation and adaptability. Cropping more productive disease-resistant genotypes that enable a mechanized production ensures greater economic returns for farmers. This study aimed to morphologically characterize and select promising castor bean accessions for mechanized cropping, mainly as a source o...
Late seed maturation improves the preservation of seedling emergence during sto...
Basso,Denise Puntel; Hoshino-Bezerra,Andrea Akemi; Sartori,Maria Márcia Pereira; Buitink,Julia; Leprince,Olivier; Silva,Edvaldo Aparecido Amaral daAbstract: Long-term survival during dry storage or longevity is a pre-requisite to avoid deterioration, leading to loss of vigor. Longevity is routinely evaluated by the ability to germinate after storage. It increases progressively during seed maturation, after the acquisition of desiccation tolerance. However, the capacity to germinate represents only a part of the success of crop establishment. How seed matu...
