Sheep farming in Latvia experienced a positive development trend: the number of farms raising sheep and the total number of sheep recorded in them have increased recently. Meat and meat products are one of the main sources of protein in diet. Sheep meat is considered to be an ecologically clean product of high quality because natural ingredients are used in animals’ nutrition. The aim of the research was to analyze the growth parameters and evaluate feed costs for fattening lambs. In 2014 sixty-nine male lambs of Latvian dark head breed were purchased and fattening results were tested. The 2nd experimental group lambs (25.7 kg) had the smallest live weight before starting fattening. Significant differences in live weight before starting fattening were observed in the 1st control, 2nd and 3rd experimental groups. The greatest increase in the average live weight per day was observed in the 2nd experimental groups of lambs (331.3 g). The greatest live weight before slaughter (50.8 kg) was found in the 3rd experimental group of lambs. The obtained results confirm that later generations of German Blackhead breed have preserved positive effects on the productive characteristics of meat.
