INFLUENCE OF FINISHING DIET ON FATTY ACID PROFILE OF LONGISSIMUS MUSCLE OF BLACK SLAVONIAN PIGS
Regarding nutritional recommendations for humans, pork in general has too high ratio of n-6 and n-3 polyunsaturated fatty acids. The n-6/n-3 index is particularly high if animals were intensively fed concentrate feeds, because the cereals like corn are rich in linoleic acid (C18:2 n-6). Traditional...

Regarding nutritional recommendations for humans, pork in general has too high ratio of n-6 and n-3 polyunsaturated fatty acids. The n-6/n-3 index is particularly high if animals were intensively fed concentrate feeds, because the cereals like corn are rich in linoleic acid (C18:2 n-6). Traditional Black Slavonian pig production is an outdoor grazing system, which includes utilization of the natural resources of pasture and oak woodland with supplement of small amounts of corn or some other grains. However, fattening with corn-based concentrate mixtures before slaughter is common. In this study, the influence of finishing diet of acorn or corn-based mixture on fatty acid profile of longissimus muscle of Black Slavonian pigs was investigated. The indication of beneficial effects of acorn was found when Black Slavonian pigs were fed acorn instead of concentrate feed during pre-slaughter fattening. Feeding acorn ad libitum for a period of three weeks prior slaughter significantly increased the content of alpha linolenic acid (C18:3 n-3) in the longissimus muscle in comparison to concentrate fed pigs (0.37 vs. 0.12, respectively; expressed as % of total fatty acid methyl esters, P ≤ 0.01). As a consequence, the n-6/n-3 ratio in the muscle of acorn finishing pigs was nearly threefold lower than in concentrate finishing pigs (24.1 vs. 69.3, P ≤ 0.01). |
