Reduction of transport-induced stress on finishing pigs by increasing lairage time at the slaughter house
نویسنده
چکیده
Materials and methods: A total of 200 pigs (129 gilts and 71 barrows) were subjected to two different lairage times at the slaughterhouse, short lairage (3 hours) and long lairage (12 hours), after a short journey (15 km, 20 minutes) by road from farm to abattoir. Blood samples were collected at the beginning of the slaughter line to determine stress markers: acute phase proteins (haptoglobin, serum amyloid A, and C-reactive protein) and neutrophil to lymphocyte (N:L) ratio. In the chilling tunnel, pH was measured in the semimembranosus muscle 45 minutes post mortem.

The experimental materials comprised 44 hybrid [female (Polish Large White x Polish Landrace) x male Duroc] growing-finishing pigs. The animals were randomly divided into two groups: 24 pigs were slaughtered immediately after transport and 20 pigs were slaughtered after a 24-hour rest period in the lairage. The meat content of pork carcasses, carcass dressing percentage, the proximate chemical ...

The study was based on data collected during 5 yr (2003-2007) and was aimed at assessing the effects of the month, slaughter house of destination (differing for stocking density, openings, brightness, and cooling device types), length of the journey, and temperature-humidity index (THI) on mortality of heavy slaughter pigs (approximately 160 kg live weight) during transport and lairage. Data we...

INTRODUCTION The effect of pre-slaughter handling on ultimate meat quality of pigs has been widely researched and reported on. Pre-slaughter handling (time of last feeding, transport, lairage, stunning) affects meat quality by influencing both the rate and the extent of acidification of the muscles post mortem. The extent of the decline in pH is determined largely by the energy concentration (g...
متن کاملEffect of rearing system and mixing at loading on transport and lairage behaviour and meat quality: comparison of free range and conventionally raised pigs.
Free range pigs, born outdoors and reared after weaning in enriched indoor accommodation, were compared with conventionally raised pigs from a farm, matched for effects on meat quality, with respect to behaviour during transport and lairage, blood chemistry at slaughter and meat quality characteristics. Pigs were either kept in farm pen groups or were mixed at loading and kept in the groups, so...
متن کاملPig Trucking & Handling – Stress and Fatigued Pig
Stress in the period during transport and around slaughter is known to influence the physiological and biochemical processes in pigs (Adeola and Ball, 1992). Pigs that become non-ambulatory without obvious injury, trauma or disease and refuse to walk, during loading, transport, unloading or while in the lairage are considered fatigued. Literature available on pig transport and slaughter suggest...
