Abstract: With increasing proportion of grain to produce ethanol or biodiesel increased and the amount of by-products of this production – dry distiller’s grain and meals, which are very good protein source for animals. The purpose of this study was to compare the effect of rapeseed meal and sunflower meal used as protein sources in compound feed feeding female lambs with a start live weight of 26 kg of Pleven Blackface sheep. Used 30 ewe lambs from Pleven Blackface sheep divided in two groups of 15 animals. Both groups of lambs received of will average quality
hay meadows. In this experience as protein sources in compound feed used rapeseed meal - 40% in one group and sunflower meal - 40% in the other group. Other components of compound feed are: corn -38%, triticale, 10%, barley - 10%, vitamin premix and salt - 2%. Rations are balanced in energy and protein to receive daily growth - 250 g, with lambs live weight 30 kg, according to Todorov et al. (2007). The resulting average daily gain was 234g and 223g, respectively for lambs feeding rapeseed meal and sunflower meal in compound feed. The expense of feed for 1 kg growth was 9.3% lower in the group fed rapeseed meal compared to the group fed with sunflower meal, respectively, 5.08 and 5,60 kgDM / kg.
