Influence of the biologically active additive All G-Rich on the fatty acid composition of meat in lambs from Midle Rodopian and Karakachan aboriginal breeds

Abstract: The purpose of this study was to determine the effect of the biologically active supplement All-G
Rich on the fatty acid composition of m. Semimembranosus by male and female lambs from the
Middle Rhodopian and Karakachan aboriginal breeds.
The object of the study are 24 lambs of Karakachan and Middle Rhodopian breed, rearing in the
sheep farm of Research Center of Stockbreeding and Agriculture – Smolyan in the period April–June
2020. The lambs were divided into 4 groups – 2 control and 2 experimental. The control group was
fed concentrated fodder. The experimental group was fed with concentrated fodder and 1% All GRich
supplement. All G-Rich is a source of protein, fat and energy. Improves the quality of meat due
to the high content of docosahexaenoic acid (DHA).
The total content of saturated and monounsaturated fatty acids is higher in the control group of m.
Semimembranosus in Karakachan than in the Middle Rhodopian lambs, as follows 49.33 per 48.07
g/100 g fat and 46.67 per 44.34 g/100g fat.
The use of the All-G Rich supplement in the diet of lambs on two breeds leads to an inverse correlation
in the results between the control and experimental group of Karakachan and Middle Rhodopian
lambs for the total content of saturated, mono- and polyunsaturated fatty acids.
The ratio between omega-6 and omega-3 fatty acids is higher in the control compared to the experimental
group lambs of the both breeds, but decreases twice when using the feed supplement All-G
Rich.
