“…This difference between evaluation days was also seen in eggs and their fractions ( Table 3), showing that, isotopically, the animal is consuming, with a variation of around 2‰ for Furthermore, due to the inclusion of cornsoybean-wheat (CSW), enrichment in the 13 C and 15 N isotope values in the diets, as well as in the eggs and fractions, was seen. This observation is consistent with other experiments in poultry (ARAUJO et al, 2011;OLIVEIRA et al, 2010;DENADAI et al, 2009;DENADAI et al, 2008;GOTTMANN et al, 2008;CARRIJO et al, 2006 The isotope fractionation factor for tissue -diet was calculated in an attempt to find the best day, after changing the diet, to collect the samples for traceability analysis. The isotope fractionation factor of the eggs and their fractions (Table 4) was different between the collection days (1-28 days and 29-56 days).…”

“…Thus, the percentages of these ingredients in the feed were as close as possible to the percentages normally used in the egg industry (Brunelli et al, 2012). The amount of MBM (2.0%) added was slightly higher than the minimum detectable amount, which according to Denadai et al (2011) is 1.5%.…”

“…Kanayama et al (2012) observed that the use of carbon and nitrogen isotope ratios to trace animal-derived flours in broiler carcasses may be affected by the addition of sugar-cane yeast, because, in the case of a 6% supplement, the yeast isotope signature cannot be discriminated from that of flour made from viscera and meat. Denadai et al (2011) detected the addition of 1.5% meat and bone meal in the albumen of eggs from poultry fed with this ingredient. In this experiment only corn, soy bran and increasing levels of MBM were used as the main components of the diets.…”

“…Furthermore, to assess whether the addition of other ingredients affects the detection of MBM, Denadai et al (2009) who used 4.5% meat flour with the addition of 3.0% wheat bran, broken rice, cotton bran, corn gluten, sugar-cane and brewers yeast concluded that the use of stable carbon and nitrogen isotopes allows their detection in eggs and its fractions (yolk and albumen) obtained from laying hens fed with an MBM-containing diet, even after the addition of other vegetal components and yeast. Therefore, the aim of this work was to assess whether the addition of other ingredients such as wheat bran, corn gluten and yeast can affect the traceability of a lower amount (2.0%) of MBM in the diet of laying hens.…”

The aim of this study was to assess whether the inclusion of low amounts of ingredients such as wheat bran, corn gluten and yeast in the diet of laying hens can interfere with the traceability of meat and bone meal (MBM) in eggs and its fractions (albumen and yolk). We used 256 laying hens distributed across eight treatment groups, which consisted of a diet based on corn-soybean-wheat (CSW) bran meal and other diets that had additions comprising gluten and/or (MBM) and/or yeast. To analyse the isotopic ratios ( 13 C: 12 C and 15 N: 14 N), on the 28 th and 56 th days, 16 eggs were randomly taken for each treatment (four for each repetition), where eight eggs (two for each repetition) were used to harvest yolk and albumen samples and the remaining eight (two for each repetition) were used to analyse the whole egg. We concluded that detection of 2.0% MBM in the egg and its fractions is possible; however, the results for treatments containing gluten and yeast were not different from those containing MBM. Therefore, the inclusion of 3.0% gluten and/or yeast does not result in different δ ResumoO objetivo foi verificar se a baixa inclusão de outros ingredientes, como farelo de trigo, glúten de milho e levedura na dieta de poedeiras, pode interferir na rastreabilidade da farinha de carne e ossos bovinos (FCOB) em ovos e suas frações (albúmen e gema). Foram utilizadas 256 galinhas poedeiras distribuídas em oito tratamentos, no qual, foram compostos de uma dieta MST a base de milho, farelo de soja e farelo de trigo e as demais dietas foram acrescidos de glúten e/ou (FCOB) e/ou levedura. Para análise da razão isotópica ( 13 C/ 12 C e 15 N/ 14 N), nos 28º e 56º dias foram tomados aleatoriamente 16 ovos por tratamento (quatro por repetição), onde oito ovos (dois por repetição) serviram para colheitas de amostras de gema e albúmen e os outros oito (dois por repetição) para ovo total. Pode-se concluir que, a detecção de 2,0% de FCOB no ovo e suas frações é possível, porém, os tratamentos com inclusão de glúten e levedura não foram diferentes dos tratamentos com inclusão da FCOB. Portanto, a inclusão de 3,0% de glúten e ou levedura na ração, não permite a diferenciação dos valores isotópicos de δ 13 C e δ 15 N do ovo e suas frações destes grupos dos que possuem 2,0% FCOB.

Stable isotopes were used to develop authentication criteria of eggs laid under cage, barn, free range, and organic farming regimens from The Netherlands and New Zealand. A training set of commercial poultry feeds and egg albumen from 49 poultry farms across The Netherlands was used to determine the isotopic variability of organic and conventional feeds and to assess trophic effects of these corresponding feeds and barn, free range, and organic farming regimens on corresponding egg albumen. A further 52 brands of New Zealand eggs were sampled from supermarket shelves in 2008 (18), 2010 (30), and 2014 (4) to characterize and monitor changes in caged, barn, free range, and organic egg farming regimens. Stable carbon (δ(13)C) and nitrogen (δ(15)N) isotopes of 49 commercial poultry feeds and their corresponding egg albumens reveals that Dutch poultry are fed exclusively on a plant-based feed and that it is possible to discriminate between conventional and organic egg farming regimens in The Netherlands. Similarly, it is possible to discriminate between New Zealand organic and conventional egg farming regimens, although in the initial screening in 2008, results showed that some organic eggs had isotope values similar to those of conventional eggs, suggesting hens were not exclusively receiving an organic diet. Dutch and New Zealand egg regimens were shown to have a low isotopic correlation between both countries, because of different poultry feed compositions. In New Zealand, both conventional and organic egg whites have higher δ(15)N values than corresponding Dutch egg whites, due to the use of fishmeal or meat and bone meal (MBM), which is banned in European countries. This study suggests that stable isotopes (specifically nitrogen) show particular promise as a screening and authentication tool for organically farmed eggs. Criteria to assess truthfulness in labeling of organic eggs were developed, and we propose that Dutch organic egg whites should have a minimum δ(15)N value of 4.8‰ to account for an organic plant derived diet. Monitoring of New Zealand egg isotopes over the past 7 years suggests that organic eggs should have a minimum δ(15)N value of 6.0‰, and eggs falling below this value should be investigated further by certification authorities.
