This modem slaughtering method for Beef was  known as CanPac A North American
Company  Canadian Meat Packers. first developed the system in the late 1950s.

The initial CanPak ‘dressing-on-the-rail’ was a semi-automated system where the
slaughterer performed most of the fold but the hide was mechanically stripped
from the beast.
The system was introduced to the Cross works in 1965. In modem abattoirs, a hilly automated system moves cattle along a disassembly line until carcasses end up as boneless beef packed in boxes.

Slaughter men, rovers, back-up labourers, along with meat graders, ticketers, checkers and maintenance men, were all pan of the using mechanical cutters, compressed knives, hide pullers, mechanical saws and other devices. This modem equipment made the job far more eliicient than in bygone years.” john Emery, a former Cross boners’ leading-hand said, ‘It was quicker too, it did just more than two cattle per minute’.

In fact, the Can Pak beef dressing system which is being introduced not only will make our meat universally acceptable but also should reduce costs. This will widen the scope of economic marketing. Our meat industry is on the march, and I am confident that its future is very bright indeed. We are particularly fortunate in being free of the scourge of foot-and-mouth disease, and as long as we remain in this felicitous situation I have no fears about the future of our meat exporting industry
