A study was carried out with 10 male lambs of Bulgarian dairy synthetic population. The animals were divided in two groups- control and experimental as the diet of the latter was supplemented with coconut oil in amount 20g/d per animal for a period of 90 days. After finishing the experiment, complete slaughter analysis was done on the half carcasses of the animals from both groups and pH 24h, colour, water holding capacity, content of myoglobin, fat, protein, moisture and ash in Musculus longissimus dorsi and Musculus semimembranosus were determined. The coconut oil supplementation led to significant increase of the contents of the subcutaneous (Р is less than 0.001) and intermuscular fat (Р is less than 0.05) in the half carcass and its individual parts as well, and influenced significantly the colour of the muscles which was darker in the lambs of the experimental group. Specific deposition of fats in dependence on the location in the carcass was observed. The content of subcutaneous fat was lowest in the neck and highest in the loin, whereas that of intermuscular fat was lowest in the leg and highest in the shoulder of the lambs. Significantly higher water holding capacity (Р is less than 0.05) in Musculus longissimus dorsi and myoglobin content in Musculus semimembranosus (P is less than 0.01) were observed, due to the differences in the type of the muscles.
