Avaliação do Metabolismo Nutricional em Poedeiras pela Técnica dos Isótopos Estáveis do Ccarbono (13C/12C) Rev. Bras. Ciênc. Avic.
Carrijo,AS; Pezzato,AC; Ducatti,C.
Os isótopos estáveis do carbono que eram utilizados em estudos ecológicos e paleoecológicos apresentaram um incremento nos últimos trinta anos, na utilização em estudos dietéticos em animais. Entretanto, existem poucas informações sobre o padrão metabólico e sobre as taxas de turnover do 13C em aves. O presente experimento estabeleceu curvas de substituição e taxas de movimentação do 13C no ovo e no fígado de aves de postura adultas, pela substituição da ração comercial por dietas compostas de grãos dos ciclos fotossintéticos C3 e C4, durante 50 dias. A diferença no conteúdo isotópico do delta per mil do carbono-13 (delta‰ 13C) entre as duas dietas foi de 16,13‰. A taxa de substituição do 13C das dietas, nos tecidos, adequou-se num modelo exponencial,...

Stradiotti,AC; Bendassolli,JA; Ducatti,C; Sartori,JR; Pelícia,VC; Araujo,PC; Maruno,MK; Pezzato,AC.
ABSTRACT The objective of this study was to evaluate the process of L-methionine incorporation in the blood plasma, liver, breast muscle, and abdominal fat of 35- to 59-d-old broiler chickens using the carbon stable isotope (12C and 13C) technique for the estimation of methionine requirements. In this experiment, 51 male broiler chickens orally received a solution of L-[13C1] methionine (92 atm % 13C) at 29 µmol/kg live weight/h for 6 h. Three birds were sacrificed for tissue collection at times 0 h (control), 0.5, 1, 2, 3, 4, 5, 6, 12, 24, 48, 72, 96, 120, 144, 168, and 336 h after the administration of the first dose. Tissue L-[13C1] methionine incorporation mass and percentage results were analyzed using Minitab 16 statistical software. Except for...

Móri,C; Garcia,EA; Ducatti,C; Denadai,JC; Gottmann,R; Mituo,MAO.
Studies on the detection of animal by-products in poultry meat are rare, and non-existent on quail meat. This study aimed at detectiong increasing levels of poultry offal meal (POM) in quail meat, using carbon (13C/12C) and nitrogen (15N/14N) stable isotopes technique. Sixty four on-day-old male quails derived from a commercial farm were randomly distributed into seven different groups, which were fed experimental diets containing 0, 1.5, 3.0, 4.5, 6.0, 7.5, and 15% of POM. Diets were formulated to contain equal energy, protein, and amino acid levels. Four individuals per treatment were sacrificed at 42 days of age for breast muscle (Pectoralis major), keel, and tibia collection, which were subsequently submitted to analyses. Isotopic δ13C and δ15N...

Studies on carbon-13 turnover in eggs and blood of commercial layers Rev. Bras. Ciênc. Avic.
Denadai,JC; Ducatti,C; Pezzato,AC; Carrijo,AS; Caldara,FR; Oliveira,RP.
This paper aimed at evaluating the influence of diets containing different isotopic values of carbon-13 turnover on the half-life of egg (yolk + albumen), yolk and albumen individually, and blood of poultry using delta‰13C isotopic variation. Commercial layers fed four experimental isocaloric and isonitrogenous diets (RC4, RC3, RMC4 and RMC3) containing different isotopic values, during an experimental period of 56 days. Turnover of the studied tissues was influenced by the experimental diets. Blood and albumen were more influenced by dietary treatments as compared to egg and yolk. The RMC3 diet induced better performance (better feed intake and higher egg production) due faster rate of carbon substitution than the RC4 diet, and lower half-life for egg...

Kanayama,JS; Pezzato,AC; Sartori,JR; Ducatti,C; Novaes,VHC; Fascina,VB; Araújo,PC; Carvalho,FB.
The objective of this study was to verify if the dietary inclusion of sugarcane yeast at levels commonly used in broiler diets influences the traceability of cattle meat meal and poultry offal meal, using the technique of stable carbon and nitrogen isotopes in the breast muscle of chickens. A number of 325 one-d-old male broilers were randomly distributed into 13 treatments with 25 birds each. Treatments consisted of a control diet based on corn and soybean meal, and the inclusion of 1, 2, 4, or 6% meat and bone meal, poultry offal meal or sugarcane yeast. At 42 days of age, six birds per treatment were randomly selected, sacrificed, and their breast muscle was collected for isotopic ration analysis. The isotopic ratio of birds fed the diet with inclusion...

Móri,C; Garcia,EA; Ducatti,C; Denadai,JC; Pelícia,K; Gottmann,R; Mituo,AOM; Bordinhon,AM.
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 (13C/12C) and nitrogen (15N/14N) 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)...

Traceability of bovine meat and bone meal in poultry by stable isotope analysis Rev. Bras. Ciênc. Avic.
Carrijo,AS; Pezzato,AC; Ducatti,C; Sartori,JR; Trinca,L; Silva,ET.
Bovine meat and bone meal (MBM) was widely used in animal diets until outbreaks of Bovine Spongiform Encefalopathy (BSE) occurred in some countries. It has not been confirmed yet whether or not BSE may be transmitted to man through chicken meat originated from poultry that had been fed diets containing MBM. Therefore, consumers nowadays express preference for meat originated from birds fed exclusively vegetable diets. This study analyzed samples of major breast muscle (Pectoralis major) using mass spectrometry of stable isotopes (carbon and nitrogen) as a means to assess the presence of MBM in broiler diets, a technique that might be used in the certification of poultry quality. A total of 150 day-old chicks were reared in five randomized treatments with...

Oliveira,RP; Ducatti,C; Pezzato,AC; Denadai,JC; Cruz,VC; Sartori,JR; Carrijo,AS; Caldara,FR.
Our goal was to trace the inclusion of poultry offal meal (OM) in diets by using carbon (13C/12C) and nitrogen (15N/14N) isotopic ratios of different tissues in order to contribute for the development of an independent technology for the certification of the feeding of broilers reared on diets with no addition of animal ingredients. Eighty one-day-old chicks were randomly distributed into five experimental treatments, that is, diets containing increasing levels of OM inclusion (0, 2, 4, 8 and 16% OM), with four replicates of four birds each. At 42 days of age, four birds per treatment (n=4) were randomly selected, weighed, and sacrificed to collect breast muscle (Pectoralis major), keel and tibia samples to determine their isotopic ratios (13C/12C e...
