Abstract

A final stage of studies was carried out with the aim of evaluating the welfare conditions of broilers in the company Abílio Antunes, city of Chimoio, from December 2012 to February 2013. For this, it was possible by describing the factors that influence the Welfare on the farm, determination of welfare indicators in Broilers and analysis of welfare conditions. To achieve the objectives, the following methodology was used: descriptive method, direct observation and determination of well-being indicators. It was worked with 39600 day-old chicks from the coBB500 line weighing 46g. During the study, mortality was obtained in the rearing of 1188 chicks corresponding to a percentage of 3%, and during transport there were 396 dead birds corresponding to 1.03%. Regarding the evaluation of welfare indicators in the slaughterhouse, it was found: the percentage of rejection is 5742 corresponding to 15.10%, the percentage resulting from the evaluation of dermatitis on the pads of the foot was (grade 0- 1009.3248 paws corresponding to 35 .4%); (grade I - 1168,992 paws - 41%); (grade II - 672,8832 paws - 23.6%), the percentage of chest contact burns was (4500 broilers - 78.91% no burns); (1000 -17.53% with slight changes); (202.4 - 3.54% with chest burns), the percentage of trauma in broilers was (4540 broilers - 79.61% without trauma); (278 chickens - 4.87% with wing trauma); (341.4 chickens -5.98% trauma to the tibia); (543 chickens -9.52% neck trauma) giving an overall average of 6.79%. After carrying out the study, it can be concluded that the factors that most influence the well-being of broilers are: unadjusted temperatures, that is, characterization by sudden drop and rise, very wet litter with high ammonia content, and high densities. of stocking outside of 12 birds/m². Regarding the remaining factor, lighting has little impact on the well-being of broilers, and the indicators that reflect the well-being of broilers are: Mortality in rearing and transport, dermatitis on the pads, contact burns on the chest, trauma, rejection percentage. However, it can be said that the well-being conditions at the Abílio Antunes company are not optimal due to the high negative percentage of well-being indicators, with the exception of mortalities (TRADUÇÃO NOSSA)
