Extract

A recent survey of the handling of commercial slaughter pigs suggested that many animals could experience long periods without food before they were killed. Because prolonged food deprivation is detrimental to carcass yield, meat quality and possibly the animals’ welfare, fasting times in pigs killed in four slaughter plants were assessed. Length of fast was estimated indirectly from the concentration of glycogen in the animals’ livers. The relationship between time of food withdrawal and liver glycogen was determined in laboratory experiments using 341 pigs killed after defined fasting periods ranging from 0 to 48h.
