Vocalization of broilers can be used to identify their sex and genetic strain REA
PEREIRA,ERICA M.; NÄÄS,IRENILZA DE A.; GARCIA,RODRIGO G..
In order to reach higher broiler performance, farmers target losses reduction. One way to make this possible is by rearing sexed broilers as male and female present diverse performance due to their physiological differences. Birds from different genetic strain also have a distinct performance at the same age. Considering that sexed flocks may present higher performance this study aimed to identify one-day-old chicks’ sex throughout their vocalization. This research also investigated the possibility of identifying the genetic strain by their vocalization attributes. A total of 120 chicks, half of them were from Cobb® genetic strain and the other half from Ross® genetic strain. From each group, a total of 30 were males and 30 females, which were previously...

Financial losses in pork supply chain: a study of the pre-slaughter handling impacts REA
REIS,JOÃO G. M. DOS; MACHADO,SIVANILZA T.; SANTOS,RODRIGO C.; NÄÄS,IRENILZA DE A.; OLIVEIRA,RONE V..
Brazil is amongst the world’s largest swine producers. However, its competitiveness has been vulnerable due to a lack of cooperation between the supply chain players. This condition makes the financial losses to be evaluated taking into account only an individual node, and most of the time, these damages are imputed by swine breeders. Living weight losses occur between the farm to slaughterhouses, and the main cause of these losses is the pre-slaughter handling, especially during animal transportation. In this research, we analyzed the pre-slaughter handling in a swine farm in Brasilândia, MS, Brazil. Analyzed data were provided by five slaughterhouses (farm clients) from the studied region, in which it was considered living weight losses, carcass...

Comparative analysis of different meat traceability systems using multiple criteria and a social network approach REA
NÄÄS,IRENILZA DE A.; MOLLO NETO,MARIO; VENDRAMETTO,ODUVALDO; CANUTO,SIMONE A..
The adoption of a proper traceability system is being incorporated into meat production practices as a method of gaining consumer confidence. The various partners operating in the chain of meat production can be considered a social network, and they have the common goal of generating a communication process that can ensure each characteristic of the product, including safety. This study aimed to select the most appropriate meat traceability system “from farm to fork” that could be applied to Brazilian beef and pork production for international trade. The research was done in three steps. The first used the analytical hierarchy process (AHP) for selecting the best on-farm livestock traceability. In the second step, the actors in the meat production chain...
