Isotopic carbon turnover in pig hoof and rib
Blaitt, Regina Maria Nascimento Augusto; Tierzo, Vivian Lo; Denadai, Juliana Célia; Kruliski, Cibele Regina de Souza; Ducatti, CarlosThe objective of this study was to evaluate the behavior of carbon incorporation and turnover in hoof and ribs of pigs at different periods of development in the search for tissues that reflect longer the former diet. We used 132 commercial hybrids (barrows and females), weaned at an average age of 21 days, distributed in a completely randomized design with four treatments on different days of substitution of c...
Effects of soil water deficit and nitrogen nutrition on water relations and pho...
DaMatta, Fábio M.; Loos, Rodolfo A.; Silva, Emerson A.; Loureiro, Marcelo E.; Ducatti, CarlosCoffea canephora plants (clone INCAPER-99) were submitted to low N (LN) or high N (HN) applications and two watering regimes (daily irrigation and irrigation every 5 days for a month). Although water potential was not altered significantly by N, HN plants showed higher relative water content than did LN plants under water deficit. Only HN plants exhibited some ability for osmotic adjustment. Plants from both N ...

Modelo teórico e experimental da reciclagem do carbono-13 em tecidos de mamífer...
Ducatti, Carlos; Carrijo, Alfredo Sampaio; Pezzato, Antônio Celso; Mancera, Paulo Fernando de ArrudaA diferença entre fontes alimentares da ordem de 14 , originárias de plantas com ciclos fotossintéticos Carbono-3 (C3) e Carbono-4 (C4) e seus subprodutos, abre novas perspectivas para o estudo do metabolismo do carbono em aves e animais de pequeno porte. Os autores propõem um modelo teórico e experimental capaz de exprimir os resultados de enriquecimento relativo, delta per mil (d ) da razão 13C/12C versus tem...
Carbon stable isotope (13C) natural abundance of some foods and its contributio...
Furuya, Valéria Rossetto Barriviera; Hayashi, Carmino; Furuya, Wilson Massamitu; Ducatti, CarlosThe aim of this study is to determine the natural abundance of carbon stable isotope (13C) of some food components and determine its contribution to the pintado juvenile growth, in laboratory conditions. 150 fishes were used with average weight of 1.39 g, and stocked in two net ponds with 125L each, during 60 days. Every 10 days a water sample was collected to analyse phytoplakton and zooplankton. Clacocera was...
Effect of glutamine on carbon (δ13C) turnover in the muscles and viscera ...
Caldara, Fabiana Ribeiro; Ducatti, Carlos; Berto, Dirlei Antonio; Denadai, Juliana Célia; Silva, Evandro Tadeu da; Garcia, Rodrigo GarófalloThe study was carried out to verify the influence of glutamine on carbon turnover in the muscles and viscera of piglets. Nine sows were bred and received diets predominantly composed by grains of C4 photosynthetic cycle plants during gestation and lactation. The piglets were weaned at 21 days of age, and 48 animals were distributed at random in two treatments: T1 = C3 diet, without glutamine supplementation; an...
