Extract

Meat production is the most important goal of sheep breeders in Iran. Crossbreeding between rams from relatively heavier breeds with ewes from light breeds (terminal crossing) is common method for increasing meat production in many countries (Bunch et al., 2004; Guney, 1990; Macit et al., 2001). The objective of this study was to compare the growth and feed-lot performance of crossbred lambs, resulted from Shall, Moghani and Afshari (three heavy breeds) rams and Kordi (a light breed) ewes. The performance of pure Kordi lambs was also adopted as a comparison benchmark.
