Broiler carcass condemnation pattern during processing

Abstract

This study aimed to identify the influence of climate pattern and rearing conditions on broiler carcass condemnations observed during processing. We evaluated the registered data of 2015 from the federal inspection files in all broiler slaughterhouses located in the state of Mato Grosso do Sul, Midwestern Brazil. The percentages of condemnations by airsacculitis, cellulitis, dermatosis, ascites syndrome, total carcass condemnations, and average broiler weight at 42 days were analyzed. Data were associated with housing systems and season of the year in which each flock was reared. Two-way ANOVA was applied to the data in a completely randomized design 4×3 (four seasons and three houses) and compared by Tukey's test. The results indicated that the housing system did not affect the studied condemnations, and seasons of the year did not change condemnation by airsacculitis; however, the other pathologies leading to carcass condemnations were affected by season. Condemnations by cellulite were higher during summer than in winter. For dermatosis, the maximum index appears during summer and the lowest during winter and spring. The ascites syndrome presented the smallest index in summer and winter, and the minimum value was found in spring. The average bird weight was higher in autumn than in winter and spring. Type of broiler rearing did not affect the carcass condemnation index. Summer was the most detrimental period regarding the condemnation rates for the pathologies studied, mainly cellulitis and dermatosis, while the highest average weight of birds was found during autumn and spring.

Time series evaluation of condemnation at export poultry slaughterhouses in southeastern Brazil (2009– 2019): a tool for optimizing resources in the poultry production chain

“…The relationship between causes of condemnation and annual variations in rainfall, humidity, and the temperature has already been studied by other authors (d'Arc Moretti et al, 2010;Belintani et al, 2019). In the present study, the only cause of condemnation for non-technological failures with an ASI difference was an ascitic syndrome, with the highest values identified in the months of July to October (P < 0.05) (Graph 3).…”

“…Technological failures were defined as those that occurred during the harvesting, transportation, or slaughtering processes. Non-technological failures were defined as other causes of condemnation, such as the presence of a pathogenic agent, precarious hygienic conditions in production, or climatic variations (Belintani et al, 2019;Ludtke et al, 2010;Schulze Bernd et al, 2020).…”

“…Non-technological causes are related to the presence of a pathogen, poor hygienic conditions in production, and climatic variations that can result in the development of airsacculitis and arthritis (Belintani et al 2019;Schulze Bernd et al 2020). On the other hand, technological condemnations are the result of failures in pre-slaughter and slaughter management stages, such as catching, transporting, hanging, and scalding the poultry.…”

“…Dermatitis is the term used by the Brazilian Federal Inspection Service to record skin diseases, except cellulitis (BRASIL, 2020). Its occurrence is related to high stocking rates, bird weight, temperature stress, and litter quality (Belintani et al, 2019;Jaguezeski et al, 2020).…”

The effect of four commercial broiler hybrids and the season on occurrence of broiler condemnations in the abattoirs

“…Ascites represents one of the main causes of condemnations in the abattoir (MASCHIO & RASZL, 2012;BELINTANI et al, 2019). This pathological condition is characterized by accumulation of fluid in the abdominal cavity produced by general causes of edema (BAGHBANZADEH & DECUYPERE, 2008), which is a progression of ascites syndrome.…”
