Abstract :In this study, the behaviour responses of the crossbred lambs [F2 insert ignore into journalissuearticles values(German Black-Headed Mutton x Merino); x F1 insert ignore into journalissuearticles values(Chios x Kıvırcık);] were compared with the Kıvırcık lambs in intensive conditions and the effects of genotype, sex and observation period on the behaviours displayed were investigated. The data were collected from 10 insert ignore into journalissuearticles values(5 male + 5 female); Kıvırcık and 10 insert ignore into journalissuearticles values(5 male + 5 female); crossbred lambs, which were weaned at the age of 2-2.5 months. The effect of genotype was found significant on the behaviours of feed consumption insert ignore into journalissuearticles values(P < 0.01);, activities towards the bedding material insert ignore into journalissuearticles values(P < 0.05);, rumination insert ignore into journalissuearticles values(P < 0.01);, lying insert ignore into journalissuearticles values(P < 0.01);, oral stereotypic behaviours insert ignore into journalissuearticles values(OSB); insert ignore into journalissuearticles values(P < 0.01); and behaviours towards animal insert ignore into journalissuearticles values(BTA); insert ignore into journalissuearticles values(P < 0.01);. Behaviours towards other animals and oral stereotypic behaviours in the crossbred lambs were 50% and 27% more than the Kıvırcık lambs, respectively. Significant differences in terms of the activities towards the bedding material insert ignore into journalissuearticles values(P < 0.05);, rumination insert ignore into journalissuearticles values(P < 0.01); and lying insert ignore into journalissuearticles values(P < 0.01); behaviours were determined between the male and female lambs. It was seen that the male lambs were more active in the breeding area. The effects of observation period were found significant on feeding insert ignore into journalissuearticles values(P < 0.01);, drinking insert ignore into journalissuearticles values(P < 0.01);, rumination insert ignore into journalissuearticles values(P < 0.01);, lying insert ignore into journalissuearticles values(P < 0.01);, standing insert ignore into journalissuearticles values(P < 0.01);, oral stereotypic behaviours insert ignore into journalissuearticles values(P < 0.01); and behaviours towards animals insert ignore into journalissuearticles values(P < 0.05);. Although the crossbred lambs were more superior for fattening program in terms of live weight gains, they showed more abnormal behaviours insert ignore into journalissuearticles values(OSB and BTA);, which are the signs of stress, in the limited breeding area, depend on the lessening of the area by the rise in their live weights.
