Introduction
Proper facility design plays a critical role in preventing cross-contamination and ensuring a hygienic environment for meat processing. Some common factors associated with transport of food is:
Stress:
Poor transportation can have serious deleterious effects on the welfare of livestock and can lead to significant loss of quality and production. Effects of transport and movement include: Stress- leading to DFD beef and PSE pork.
Loss in weight during transportation
Some loss in live weight during transport. Loss is greater than loss solely by fasting for similar period.
Loss in weight andĀ Loss in water.
Factors affecting the loss are:
- Bodily condition
- State of repletion
- Season
- Journey time
| S.No. | Species | LossĀ inĀ weightĀ |
| 1. | Pig | 2.2Ā toĀ 5.4Ā kgĀ duringĀ 24Ā hr. |
| 2. | Sheep | 3.6Ā kgĀ duringĀ 24Ā hr. |
| 3. | CalfĀ (150Ā kg) | 4.0Ā kgĀ duringĀ firstĀ dayĀ ofĀ travel
1.8Ā kgĀ onĀ secondĀ dayĀ ofĀ travel |
| 4. | BullockĀ (610Ā kg) | 30Ā toĀ 40Ā kgĀ duringĀ firstĀ dayĀ ofĀ travel
5.0Ā toĀ 6.0Ā kgĀ onĀ secondĀ dayĀ ofĀ travel |
| 5. | Lambs | 7-8%Ā ofĀ liveĀ weight |
Transport Mortality
Extremes of temperature: Especially heat can be responsible for many losses in livestock.
Pigs: pathological changes
āAcute cardiac dilation & acute pulmonary hyperemia
āLung: not conical but oval
āHeavy & firmal than normal
āFinger impression remain on palpation
