“…It has been reported that the d 15 N of animal tissue is usually less influenced by specific dietary input and more variable due to metabolic factors. 1,39 Moreover, it has been stressed that the nutritional quality of dietary ingredients could affect diet-animal shifts: in general, better quality diets (i.e. with a lower C/N ratio) lead to a lower d 15 N enrichment.…”

The stable isotope ratios ( 13 C/ 12 C, 15 Recently, several papers have been published about the application of stable isotope ratio analysis (SIRA) using isotopic ratio mass spectrometry (IRMS) to animal products. The aims of these studies were to obtain dietary reconstruction, to study animal movement patterns, 1-5 and to characterise the geographical origin. [6][7][8][9][10][11][12][13][14][15][16] Another important aim could be to study and quantify the alteration of stable isotope ratios (SIRs) in milk by substituting a C 3 plant diet with maize. This could be important in order to protect milk and milk derivatives produced using traditional or 'organic' practices of pasture compared with products produced with cheaper diets based on maize derivatives. There have been recent reports about this in defatted meat, [17][18][19] in related fat, 17 in several animal tissues such as blood, plasma, liver, kidney, cow hair 20 and in sheep faeces. 21 In these papers it was shown that there is a strong correlation between the SIR of carbon and the amount of maize in the diet. It was also shown that the degree of this alteration depends on the component or body tissue considered, due to its biochemical composition and turnover rate. 22 On the other hand, variations in the SIRs in milk and milk derivatives following suitable experimental design have not been so extensively explored. Metges et al. 23 investigated the 13 C/ 12 C of CO 2 breath, bulk milk and serum by exchanging a C 3 plant with a C 4 plant diet, and vice versa. Wilson et al. 24 studied the contribution of body protein to milk protein, changing abruptly from a C 3 to a C 4 diet. More recently, Knobbe et al. 25 followed the variation in stable carbon and nitrogen isotopic composition under different feeding regimes. It was concluded that, to obtain more detailed information on the influencing factors, the analysis of the SIRs of other elements such as oxygen and hydrogen may be necessary.In this study we considered around 130 cows stabled in two farms and supplied with diets made up of different kinds of C 3 plants and different amounts of maize. The different feed ingredients, the overall diet and the relevant milk (casein, lipid and some bulk samples) were subjected to analysis of 13

“…Predictable enrichment of 15 N with increasing trophic level allows for estimation of an animal's relative trophic position (gannes et al 1998, Vanderklift andPonsard 2003), whereas δ 13 C values reflect sources of primary productivity and thus can be used to assess diet and habitat use (gannes et al 1998, kurle and Worthy 2001, Rubenstein and hobson 2004, kurle and gudmundson 2007.…”

Discrimination Factors for Stable Isotopes of Carbon and Nitrogen in Blood and Feathers from Chicks and Juveniles of the California Condor

Abstract. Stable-isotope ratios of carbon ( 13 C/ 12 C; δ 13 C) and nitrogen ( 15 N/ 14 N; δ 15 N) in animal tissues are analyzed to estimate animal foraging ecology because these ratios reflect those of an animal's diet. This reflection is generally indirect, as stable-isotope ratios change with trophic level. These differences, called discrimination factors (reported as Δ), vary considerably by species and tissue. Variations in discrimination factors used in stableisotope mixing models can lead to inaccurate estimates of diets. Therefore, determining accurate discrimination factors specific to species and tissue is important. We established the Δ 13 C and Δ 15 N values between diet and blood and feathers from chicks and juveniles of the California Condor (Gymnogyps californianus). hatchlings were fed rats for 76-119 days, whereas juveniles were fed dairy calves for 64 days. The mean Δ 13 C and Δ 15 N values (± SD) between chick feathers and rat muscle were 0.4 ± 0.4‰ and 3.1 ± 0.2‰, respectively; those between chicks' whole blood and rat muscle were -0.7 ± 0.1‰ and 1.7 ± 0.1‰, respectively. The mean Δ 13 C and Δ 15 N values between juvenile condors' plasma and calf muscle were 0.9 ± 0.2‰ and 3.3 ± 0.7‰, respectively; those between juveniles' red blood cells and calf muscle were 0.3 ± 0.3‰ and 1.8 ± 0.1‰, respectively; and those between juveniles' whole blood and calf muscle were 0.3 ± 0.3‰ and 1.9 ± 0.2‰, respectively. We report the first discrimination factors for the Cathartidae (New World vultures), and our findings will have important applications in studies of the critically endangered California Condor's foraging ecology.

Consistent information on meat products consumed by the public is essential. The technique of stable isotopes is a powerful tool to recover consumers' confidence, as it allows the detection of animal byproduct residues in poultry meat, particularly in quail meat. This study aimed at checking the presence of poultry byproduct mixtures in quail diets by applying the technique of carbon ( 13 C/ 12 C) and nitrogen ( 15 N/ 14 N) stable isotopes in quail breast muscle, keel, and tibia. Sixty four one-day-old male quails were obtained from a commercial farm. Birds were housed in an experimental house from one to 42 days of age, and were randomly distributed into 8 experimental treatments, and fed diets containing poultry offal meal (POM), bovine meat and bone meal (MBM) or poultry feather meal (PFM), or their mixtures. Four birds per treatment were slaughtered at 42 days of age, and breast (Pectoralis major), keel, and tibia were collected for analyses. The inclusion of animal byproducts in quail diets was detected by 13 C e 15 N analyses in the tissues of the birds; however, it was not possible to specify which byproducts were used. It was concluded that quail meat can be certified by the technique of stable isotopes.
