Key Points

This research investigates the effects of perilla meal on growth performance, carcass traits, and fat composition in pigs.
Used 48 finishing pigs, divided into three feeding groups with 0%, 5%, and 10% perilla meal.
Analyzed growth performance metrics and fatty acid compositions in pig fat.
Conducted four replicates per feeding group.
The 5% and 10% perilla meal groups had significantly higher feed intake (P<0.05) compared to the control group.
The alpha-linolenic acid levels increased significantly in the 5% and 10% groups, with values 2.4 and 3.8 times higher compared to the control in subcutaneous and intramuscular fat, respectively.
The n-6/n-3 ratio improved toward the recommended value of '4' without affecting growth or carcass traits.

Examines perilla meal's impact on pig growth and fat composition, suggesting health benefits.
