Özet
Study was carried out to determine the effects of shade allowance and cafeteria feeding on feeding behaviour of Awassi lambs kept in hot climate condition. The two housing methods indoor and outdoor and two feeding methods (single and cafeteria feeding) were tested (ISF, OSF, ICF and OCF). The thirty two lambs 3 months old male were divided into four groups and housed individually for 42 days. Results showed that daily gain, feed efficiency, the intake of water, protein, energy and fibre, the selection of energy, protein and fibre and water/feed ratio were affected by treatments (p<0.05). Indoor lambs, made a diet containing 29.27% B, 27.10% C, 11.63% CSM, 3.30% FFS, 19.17% A and 9.52% WB while outdoor ones made a diet having 24.75% B, 27,12 C, 9.60% CSM, 9.22% FFS, 16.12% A and 13.20% WB. Eating, drinking and standing were significant at (p>0.05) while ruminating and lying were significant at (p<0.001) respective groups ISF, OSF, ICF and OCF. In conclusion, single fed Awassi lambs kept in outdoor in hot climate showed less ruminating but more lying behaviour while given opportunity to choose a diet they ate more concentrate feed ingredients such as full fat soya and wheat bran without changing their behaviour patterns. Cafeteria feeding in lambs allows physiological arrangements against heat stress in outdoor housing condition by dietary self selection and by tuning respiratory and circulatory systems.
