Studies of bruises, as detected on carcasses at the slaughterhouse, may provide useful information about the traumatic situations the animals endure during the pre-slaughter period. In this paper, we review scientific data on the prevalence, risk factors and estimation of the age of bruises in beef cattle. Risk factors such as animal characteristics, transport conditions, stocking density, live...

Meat quality and (anti)oxidative metabolism of m. pectoralis superficialis (MPS), m. gastrocnemius (MG) and m. iliotibilialis lateralis (MIL) from turkey toms were analysed. After slaughter, pH of MPS and MG decreased and electrical conductivity of the MPS increased. The MG had generally higher pH values. The meat lightness (L) and redness (a) increased in MG and MPS after slaughter. The MPS al...

This article discusses research that was conducted to optimise new electrical-stimulation technologies and to elucidate the effects of pre-slaughter dehydration of lambs. A change in lamb processing to a focus on eating quality has increased the uptake of new electrical technologies. Our research was aimed at understanding how carcase response to electrical stimulation is affected by genotype, ...

The most common commercial slaughter method for portion-sized rainbow trout is asphyxiation in ice slurry. This method is however widely believed to expose the fish to unnecessary pain and suffering. The industry is consequently seeking an alternative method, which offers improved welfare of the fish at slaughter. Electric stunning of fish in water is identified as a suitable method. Parameters...

The objective of the current review is to highlight biochemical processes and products, from slaughter to the time of beef consumption, that relate to response to stress at slaughter, meat quality and consumer health. Biochemical processes and products involved in the use of catecholamine and dopamine levels at slaughter, in predicting meat quality, are reviewed. Furthermore, meat quality chara...

The present study was aimed to assess the influence of brown marine algae and vitamin E (VE) (160 ppm α-tocopheryl acetate) on stability of chicken meat enriched with fish oil. In this study, 360 d-old broilers (Arbor Acres Plus) were randomly assigned to 6 treatment groups with 4 replicates of 15 birds in each. Experimental groups consisted of corn-soybean basal diet (C), corn-soybean basal di...

the aim of this study was to determine the principal reasons for condemnation of broiler poultry carcasses and its economic losses in namin slaughter-house of iran from  february 2008 to  march 2009 . in this period, 2741794 poultry were slaughtered which were7662237 kg live weight and 5560963 kg eviscerated meat .from these , 20479 carcasses responsible for 0.74% of total slaughter with overal...

Background: The regression equations of Slaughter and Dezenberg, which are based on mixed ethnic samples, are currently recommended for predicting body fat from skinfold-thickness measures in prepubescent children of African ancestry. These equations contain methodologic problems that could make them inappropriate for African children. Objective: The objective was to apply the Slaughter and Dez...

Fasting pigs before slaughter has many advantages such as feed saving (2-3 kganimal), and increased food safety by reducing the risk of viscera rupture and pathogen contamination of carcasses during the evisceration process (Miller et al., 1997). Other potential advantages are an improvement in meat quality (Tarrant, 1989). Indeed, some studies have shown that fasting before slaughter improves ...
