Última Effect of diet dilution ratio at early age on growth performance, carcass characteristics and hepatic lipogenesis of Pekin ducks Rev. Bras. Ciênc. Avic. Wu,L; Guo,X; Fang,Y. This study was conducted to test the hypothesis that proper diet dilution ratio at early age might improve feed conversion ratio (FCR) and reduce body fat deposition of meat-type ducks. One hundred and fifty 1-day-old male and female White Pekin ducks (44.5±1.0 g) were randomly assigned into three treatments with five replicates (pens) of 10 birds each, respectively representing the experimental diets with 0 (control), 40 or 60% rice hulls inclusion in the basal diet between 8 and 14 d of age. The basal diet was fed before and after this period. The results showed that diluting the diet with 40% rice hulls increased (p < 0.05) feed intake, decreased adjusted (excluding rice hulls) feed:gain and body weight gain of ducks during the diet-dilution period;...

Wu,L; Huang,X; Shi,K; Tan,R. Lutein supplements are often used to pigment and enrich layer chicken eggs. This experiment was conduced to compare the bioavailability of free and esterified lutein, by depletion method. Forty chickens were randomly divided into two groups. After 2 weeks of washout period, when all birds were fed the same low lutein basal diet, the two groups were fed for another 2 weeks with diets supplemented with free lutein or esterified lutein. Two experimental diets were supplemented with the same amount of 15 mg lutein/kg. On day 0 (baseline) and days 3, 7, and 14, birds fasting morning plasma samples were collected and stored for lutein analysis by high performance liquid chromatography method (HPLC). Results showed that: 1) Plasma lutein concentration increased... Tipo: Info:eu-repo/semantics/article Palavras-chave: Bioavailability; Depletion method; Free lutein; Layer hens; Lutein ester.
