Abstract | The current study investigated the impact of different feeding regimes on behaviours, body condition score and blood parameters of male camels in rutting season. twenty eight male dromedary camels randomly were divided into seven feeding regimes, twice daily fed on normal ration, once daily fed on normal ration but the same quantity as group 1, fed restricted diet before rutting season for 4 weeks then they fed control diet during rut season, fed restricted diet during rutting season, fed restricted diet before and during rutting season, fed same quality and quantity of control diet but offered once alternative day. Behavioural data had been collected for 66 days twice per weeks for feeding related behaviour, activity and aggression using instantaneous scan sampling. Moreover, blood samples had been collected at the end of observation period to estimate some serum blood parameters and some blood hormones. The results revealed that the standing time was significantly increased in control and daily once feeding groups when compared to other treated groups, in contrast our data did not reveal any significant difference in lying time. Moreover, feeding and rumination time was significantly affected by feeding regime where restricted and alternative feeding was significantly higher than control and daily once feeding. Regarding to behavioural patterns frequency, camel of control group are significantly exhibit more aggressive behaviour when compared to camels of other feeding systems groups. In addition, there is significant decrease in drinking behavior frequency in control group in comparison to daily once feeding or restricted (during or before + during) groups. Additionally, testosterone, urea, calcium, phosphorus, total protein levels in camels of infrequent fed restricted group had been significantly decreased when compared to control group. In summary we concluded that feeding regimes significantly can result in changes at the levels of behaviour and blood parameters of rut camels.
