| ABSTRACT The objective of this study was to evaluate the behavior of immunocastrated male pigs compared with females and castrated males during the period before and after full immunization. A total of 30 animals were divided into three treatments, with ten animals in each (females, barrows, and immunocastrated males). The experiment was divided into three periods: 70 to 80 days of age (period 1), 81 to 110 days of age (period 2), and 111 to 140 days of age (period 3). The behavior of animals during these stages was evaluated. Immunocastrated males showed a higher rate of aggressive and sexual behavior during period 2, which decreased after the second vaccine dose. Both barrows and immunocastrated males presented high locomotion in period 1, reducing the... |

| ABSTRACT The objective of the present research was to study the incidence of broiler carcass condemnations over eleven years and identify the productive phase that causes greater loss in slaughter process. The origin of these condemnations was determined before and after fasting. Evaluated broilers were reared in positive pressure warehouses and slaughtered between 28 and 34 days old with carcass weight ranging from 0.7 to 1.4 kg. Fasting occurred, on average, 9 h before the slaughter. Condemnation and slaughter data were collected from 2004 to 2014 in a slaughterhouse with slaughter capacity of 120,000 broilers/day. The causes of rearing condemnations were airsaccullitis, arthritis, abscess, ascites, cachexia, cellulitis, colibacillosis, dermatosis,... |

| Ammonia (NH3) emissions from broiler production can affect human and animal health and may cause acidification and eutrophication of the surrounding environment. This study aimed to estimate ammonia emissions from broiler litter in two systems of forced ventilation, the tunnel ventilation (TV) and the dark house (DH). The experiment was carried out on eight commercial broiler houses, and the age of the birds (day, d), pH and litter temperature were recorded. Broilers were reared on built-up wood shaving litter using an average flock density of 14 bird m–2. Temperature and relative humidity inside the broiler houses were recorded in the morning during the grow-out period. A factorial experimental design was adopted, with two types of houses, four replicates... |
