“…The pH results allowed us to suppose that there is greater association of preslaughter handling variables (T1, T3, T4 and T2), followed by T5 and T6; also, that the other variables are little related to pH. Corroborating this study, LUDTKE et al (2012), after analyzing pH, color, water-holding capacity, and drip loss, observed that the appropriate pre-slaughter handling did not influence meat quality, and that the resting time reduced the level of animal stress.…”

“…The sudden environment change is one the main pre-slaughter handling problems (LUDTKE et al, 2012). Other problems, such as fasting time; human-animal interaction; operations of handling, loading, density, transport, and unloading; transport time and distance from farm to slaughterhouse; climatic conditions; and resting period at the slaughterhouse, may significantly affect animal homeostasis .…”

ABSTRACT:The aim of this study was to investigate the effect of pre-slaughter handling on the occurrence of PSE (Pale, Soft, and Exudative) meat in swine slaughtered at a commercial slaughterhouse located in the metropolitan region of Dourados, Mato Grosso do Sul, Brazil. Based on the database (n=1,832 carcasses), it was possible to apply the integrated multivariate analysis for the purpose of identifying, among the selected variables, those of greatest relevance to this study. Results of the Principal Component Analysis showed that the first five components explained 89.28% of total variance. In the Factor Analysis, the first factor represented the thermal stress and fatiguing conditions for swine during pre-slaughter handling. In general, this study indicated the importance of the pre-slaughter handling stages, evidencing those of greatest stress and threat to animal welfare and pork quality, which are transport time, resting period, lairage time before unloading, unloading time, and ambience.

“…In probiotic, pH value was slightly numerically lower than control. According to (Komiyama, 2006;Ludtke, 2009), due to the rapid metabolic transformation of glycogen into lactic acid, which results in achieving ultimate pH before carcass cools, causing protein denaturation, and consequently, meat becomes pale, soft and exudative. According to (Gheisari, 2011) the extent of oxidative rancidity in a fat may also be determined by its TBA number.…”

Abstract:The aim of the study was to evaluate the effect of dietary probiotics on broiler growth performance, organ development and meat quality in replacing oxytetracycline. Dietary treatments were control (basal diet without additives), antibiotic (basal diet with 0.05% oxytetracycline), basal diet with Bacillus subtilis and basal diet with Lactobacillus spp. A total of 192 birds were randomly allotted to four dietary treatments with four replicates having 12 birds each. Feed and water were supplied ad libitum. The results of the current study revealed that growth performances of broiler did not show significant difference (P>0.05) among the treatments. Body weight and weight gain were numerically higher and FCR was numerically lower in broilers fed a diet containing 2 different single strains of probiotic than control. Though there were no treatment effects (P>0.05) on the weights of the liver, heart, kidney, spleen, gizzard, intestine and dressing percentage, but abdominal fat content was found significantly higher (P<0.05) in antibiotic treated group than that of single strain probiotic (Lactobacillus spp.) feeding group. Significant differences were also observed in meat color values where antibiotic fed broiler meat showed higher redness, lower lightness and yellowness and birds fed the control feed had higher lightness and yellowness of meat than probiotic fed chicken. TBA, P H and cooking loss were not affected by the treatments. Therefore, we concluded that use of selected probiotics resulted in improved performance parameters and reduced abdominal fat pad in broiler chickens. Moreover, addition of the probiotics in broiler diet for replacing antibiotic could be utilized for safe poultry meat production.

“…In addition, another issue related is the wind speed while travelling (TABLE 2). Management process speed may cause stress for animals during truck loading, travelling and unloading operations (LUDTKE et al, 2012). Assessing this stress may further help reducing the losses (CORDEIRO et al, 2012;MIRANDA et al, 2012).…”

Financial losses in pork supply chain: a study of the pre-slaughter handling impacts

et al. 2015

View full text Add to dashboard Cite

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 bruising, animal injury, and death rate. The results indicated that total financial losses represent 160 thousand dollars per year, when taking into account the supply chain management.KEYWORDS: supply chain management; pork production; economic impact. PERDAS FINANCEIRAS NA CADEIA DE SUPRIMENTOS DE SUÍNOS: UM ESTUDO DOS IMPACTOS DO MANEJO PRÉ-ABATERESUMO: O Brasil encontra-se entre os maiores produtores de carne suína do mundo; entretanto, sua competitividade tem sido prejudicada pela falta de cooperação entre os atores da cadeia de suprimentos. Isso faz com que as perdas financeiras sejam avaliadas em cada nó, individualmente. Na maioria dos casos, as perdas são computadas pelos produtores de suínos que absorvem os prejuízos. As perdas de peso vivo ocorrem geralmente durante o manejo pré-abate, principalmente durante o processo de transporte. A pesquisa foi realizada na cidade de Brasilândia, Estado de Mato Grosso do Sul, Brasil. Foram analisadas as operações de manejo pré-abate na granja e os dados fornecidos por cinco frigoríficos, considerando as perdas de peso vivo, as escoriações de carcaça, animais lesionados e a mortalidade. Os dados foram relacionados com o volume comercial de vendas do ano de 2012. Os resultados indicaram que as perdas financeiras corresponderam, neste caso, a 160 mil dólares, levando-se em conta os valores que deixaram de ser obtidos pela cadeia de suprimentos suinícola.PALAVRAS-CHAVE: cadeia de suprimentos; produção de suínos; impacto econômico.
