Última Performance of broilers submitted to high CO2 levels during incubation combined with temperature fluctuations at late post-hatch Rev. Bras. Ciênc. Avic. Fernandes,JIM; Bortoluzzi,C; Esser,AFG; Contini,JP; Stokler,PB; Faust,D. Incubation represents around 1/3 of the life cycle of broilers of modern strains; therefore, the appropriate management of this period is crucial to ensure the quality of the neonate. An experiment evaluated the effect of carbon dioxide concentrations during incubation on the live performance, heart morphology, and differential leukocyte count in the blood of broilers submitted to fluctuating temperatures between 35 and 42 days of age. In total, 2,520 fertile eggs were distributed according to a completely randomized design with four CO2 concentrations (4,000; 6,000; 8,000 and 10,000 ppm) during the first ten days of incubation, after which all eggs were incubated at the same CO2 level (4,000 ppm). After hatching, male chicks were placed in the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Cyclic variation of temperature; Heterophil/Lymphocyte ratio; Hypercapnia.

Bras. Ciênc. Avic. Esser,AFG; Gonçalves,DRM; Rorig,A; Cristo,AB; Perini,R; Fernandes,JIM. ABSTRACT The objective of this study was to evaluate the supplementation of guanidinoacetic acid (GAA) and L-arginine (L-Arg) as creatine precursors to vegetable diets on the carcass yield and meat quality of broilers subjected to two days of heat stress before slaughter. A total of 1260 broiler chicks were distributed according to a completely randomized design into four treatments with nine replicates of 35 birds each. The treatments consisted of: T1 - vegetable diet based on corn and soybean meal (control diet); T2 - control diet with the inclusion of meat meal (3%); T3 - control diet supplemented with GAA (0.08%); and T4 - control diet supplemented with L-Arg (0.8%). The birds were submitted to heat stress for two days before slaughter (from 42 to 44... Tipo: Info:eu-repo/semantics/article Palavras-chave: Abdominal fat; Creatine; Meat quality; Nitric oxide.
