Özet

Effects of daily protein intake levels on oral stereotypic behaviours (OSB) in energy restricted lambs were investigated. Thirty-eight male lambs were randomly allotted to three treatments. Lambs in the first group (AL) received their ration (12.1 MJ ME/kg DM; 148.6 g CP/kg DM) at ad libitum level, whereas the second group (RP1) (12.1 MJ ME/kg DM; 177.4 g CP/kg DM) and the third group (RP2) (12.1 MJ ME/kg DM; 214.9 g CP/kg DM) received their rations at restricted levels. Recording of behaviours was carried out once a week using time sampling technique during a 7-week experimental period. OSB were significantly (P < 0.001) affected by the treatments. RP2 group showed higher oral stereotypies than the others. It was concluded that increasing the daily protein intake under energy restricted conditions may have additive effects on the development of stereotypic oral behaviours.
