Black bone syndrome in chiken meat Rev. Bras. Ciênc. Avic.
Baldo,GAA; Almeida Paz,ICL; Alves,MCF; Nääs,IA; Garcia,RG; Caldara,FR; Gavilan,CWS.
Black bone syndrome (BBS) affects poultry industry, and it is caused by the darkening of the tissue adjacent to the bone due to leak age of bone marrow contents during cooking. The objective of this experiment was to estimate BBS incidence in chicken thighs. A completely randomized experimental design, with two treatments (refrigerated or frozen) of 50 replicates each, was applied. The influence of BBS on meat quality was assessed according to bone lightness (*L), and meat appearance and sensorial characteristics. Lightness was measured using a colorimeter (Minolta® 410R) positioned on the proximal epiphyseal growth plate. Meat quality was evaluated after roasting by assigning scores for appearance (acceptable = no darkening, intermediate = little...

Equilibrium Condition during Locomotion and Gait in Broiler Chickens Rev. Bras. Ciênc. Avic.
Alves,MCF; Almeida Paz,ICL; Nääs,IA; Garcia,RG; Caldara,FR; Baldo,GAA; Nascimento,GR; Amadori,MS; Felix,GA; Garcia,EA; Molino,AR.
ABSTRACT The experiment was carried out with the objective of evaluating a methodology to estimate the angulation and equilibrium condition, relating them to gait score and the main diseases of the locomotion system in males and females of commercial broiler strains. A completely randomized experimental design in a factorial arrangement (2x2) was applied, consisting of two sexes and two genetic strains, with five replicates of 53 chickens each. The following characteristics related to broiler locomotion were studied: gait score (GS); incidence of Valgus (VAL) and Varus (VAR) deformities and of pododermatitis (POD); body angle relative the ground (ANG); equilibrium condition (EC); body weight (BW) and breast weight (BrW); and incidence of femoral...

Influence of genetic strain and season on back scratch lesions in broilers Rev. Bras. Ciênc. Avic.
Pilecco,M; Almeida Paz,IC de L; Tabaldi,LA; Nääs,I de A; Garcia,RG; Caldara,FR; Alves,MCF; Felix,GA.
This study aimed at evaluating the influence of genetic strain, sex, and season on the incidence of back scratches during the rearing period. Male and female broilers of two genetic strains reared during the hot or cold season were evaluated. This meta-analysis included 894 samplings in 351 broiler houses of contracted farms located in the state of Mato Grosso do Sul, Brazil, in 2010. Broilers of all ages (1 to 43 days) were sampled, capturing 2% of the birds in the house at each sampling. Each flock was evaluated twice, in 21-day intervals. Broilers were reared as single-sex flocks; there were no straight-run flocks. Scratch lesions were classified as present or absent. Strain A broilers presented lower scratch rates (p < 0.05) than strain B birds....

Productive, Qualitative, and Physiological Aspects of Layer Hens Fed with Propolis Rev. Bras. Ciênc. Avic.
Belloni,M; Almeida Paz,ICL; Nääs,IA; Alves,MCF; Garcia,RG; Caldara,FR; Seno,LO.
ABSTRACT Laying hens reared under tropical conditions are usually under heat stress. Propolis is known for its pharmaceutical properties, such as increasing cell tolerance to hyperthermia, because of its antioxidants effects. This study aimed at evaluating the influence of different dietary propolis inclusion levels on the performance, egg quality, and bird surface temperature of layers. In this experiment 120 55-wk-old Isa Brown(r) layers were distributed according to a completely randomized experimental design into four treatments (0, 1, 2 and 3% dietary propolis inclusion levels), with three replicates of ten birds each. Performance and egg quality parameters, and birds' surface temperature were evaluated. Egg production, egg mass, feed intake, and feed...
