| ABSTRACT This study aims to examine the effects of environmental enrichment (EE) practices on some physiological and behavioral parameters of broiler chicks. A total of 280 one-day old Ross 308 mixed-sex broiler chicks with an average initial body weight of 44.5±0.37 g were used in a 42-d trial. Broiler chicks were randomly allocated to 20 pens composed of 14 birds in 1x1.4m sized floor area. Each of the EE treatment consisted of 5 replicate pens (70 chickens per treatment). The treatments were 1) control; 2) perch for EE; 3) ball for EE; 4) mirror for EE; and 5) dust for EE. Final body weights, tonic immobility test results, and rectal temperatures were recorded. Spleen, liver, and bursa fabricius weights were measured. The blood biochemistry of birds was... |

| The objective of this study was to assess the effect of the inclusion of passionflower (Passiflora alata) in diets on performance, behavior, heterophil/lymphocyte ratio (H/L), corticosterone plasma levels (CPL) and immune response of quails. The study was carried out using 192 birds, distributed in randomized blocks with 4 diets (0, 125, 250 and 375 and 0, 250, 500 and 750 mg of passionflower/kg of feed for the rearing and laying period, respectively), 8 replicates and 6 birds per experimental unit. The rearing period began when birds were 28 days of age and it lasted for 15 days. In this phase, it was evaluated daily feed intake, daily weight gain, feed conversion, viability, tonic immobility time, intensity of injuries, behavior, heterophil/lymphocyte... |

| ABSTRACT The objective of this study was to evaluate the effect of chamomile extract on Japanese quail on their performance, animal behavior, tonic immobility, body injuries, and surface temperature. The trial was conducted using 108 quail distributed in a completely randomized experimental design, with three treatments (0, 2.5, and 5.0 g chamomile/kg of feed), six replicates, and six birds per treatment, evaluated in six measures repeated in time (14, 28, 42, 56, 70, and 84 days of trial). The inclusion of chamomile presented a quadratic effect on sitting behavior, estimating the inclusion of 1.8 g chamomile/kg to maximize this behavior. There was a decreasing linear effect for aggressive pecking, that is, the higher the inclusion of chamomile in the... |
