A growth trial and digestibility trial were conducted to examine the effect of feed particle size on the performance,nutrient digestibility,gastric ulceration and intestinal morphology in pig fed barley-based diets
Barley was processed through a hammer mill to achieve four diets varying in particle size
sixty-four entire male pigs were used in the growth trial and the diets were fed ad libitum between 31 kg and 87 kg live weight
Following slaughter,stomach and ileal tissues were scored for integrity and histological measurements taken
twenty-four entire male pigs were used in the digestibility trial,Witch involved total faecal collection.
Over the entire growth phase, there were no difference in average daily gain and feed conversation ratio between pig fed diets of different particle size.
