ABSTRACT



In the experiment, goat kids of white improved breed and ram lambs of the Polish Lowland sheep fattened up to 150 days, were studied. After weaning, the animals at the age of about 70 days old were fattened "ad libitum" with all-mash pelleted feed CJ the additive containing 6.1 MJ EN and 182 g of crude protein, and meadow hay additionally. The main aim our study was determined the differences in fatty acids compositions of intramuscular fat of goat kid and ram lambs, fed with the same feed and kept in the same conditions. Results of the study showed that lambs were significantly heavier (36.64 kg) and had got a higher weight of warm carcass (16.67 kg). The kid meat showed significantly higher content of protein (20.21%) and mineral compounds (1.13%) and lower fat content (2.28%). Lamb meat contained more dry matter as well as crude fat and less protein and mineral elements than goat meat. Muscles of goat kid characterized 3.55 p.j. (percentage units) lesser contents of palmitic acid (C16:0 ) and 4.33 p.j. of stearinic acid (C18:0 ). Significance of differences was confirmed statistically. Among determined monosaturated acids dominated oleinic acid (C18:1 ): in goat kid tissue 54.1% and ram lambs tissue 47.5%. From among acids polyunsaturated significant differences stepped out among fatty acids; C18:2 , C18:3 , C20:4. In the researcher's study, this indicator was slightly below this optimum ratio and ranged from 1.60 for goats and 1.29 for rams. In the experiment, favorable proportion of UFA:SFA characterized of goat kids (1.69) incomparision with ram lambs (1.22). The differences among studied animals were significant statistically.

Key words: kids, rams, meat, fatty acids.
