Basic Carcass Characteristics of Lambs of Šumavská Sheep and its Crossbreds with Suffolk and Texel

Popis výsledku v původním jazyce

The main aim of the study was to evaluate basic carcass characteristics of purebred lambs of Šumavská breed (S) and its crossbreds with Suffolk (SF) and Texel (T). An integral part of the study was the evaluation of the effect of genotype on weights and proportions of kidney, kidney fat and basic non-carcass traits and composition of tissues in the left leg. The experiment was carried out on an organic farm in Proseč in 2015 and three different genotypes were included in the experiment: S 100 (n = 8), T 75 S 25 x S (n = 11) and T 75 S 25 x SF (n = 8). All lambs were males. As expected the genotype had a significant effect on most of the indicators. Lambs were slaughtered at approximately the same age, however in crossbreds (T 75 S 25) x SF the highest daily gain (0.168 g/day) and carcass yield (44.71%) were found. The best conformation score (3.87) and the highest heart and liver weights and proportions: (0.20 kg and 0.55%) and (0.53 kg and 1.46%) respectively were found in this group. Also the levels of muscle and fat in the left leg were 2.05 kg and 79.77%. In contrast, in purebred lambs of Šumavská sheep the lowest daily gain (0.124 g/day), carcass yield (38.38%) and proportion of muscle + fat in left leg (74.60%) were found. The results of the experiment indicate that use of commercial crossing of ewes of Šumavská breed with rams of meat breeds has a positive impact on growth and carcass quality of lambs. However, due to the relatively low number of lambs in our experiment it will be necessary to continue in monitoring of these genotypes.
