Abstract
This study was carried out on a flock of Baladi goat breed belonging to the farm of Faculty of Veterinary Medicine, Zagazig University and a private farm, at Hehia city, Sharkia governorate on a total number fourty baladi goats, apparently healthy, aged from 9-18 months were used to and divided into 20 goat on each system of housing either insemi-intensive system and village system to investigate the effect of dominance hierarchy on ingestive ( feeding, drinking and rumination) , aggressive and eliminative behaviour( frequency of urination and defecation) of goat in relation to housing system. The animals were allocated randomly into two separate, equal groups (4 males, 16 females). The results revealed that there was a significance difference (P<0.05)in mean frequency and time of ingestive, aggressive and eliminative behaviour, of goats with dominance index > 0.66 were higher than goats with dominance index(0.33-0.66)and goat with dominance index<0.33 in semi-intensive system and village system respectively. As the previous behaviour in semi-intensive system was increased in this system in comparison with village system. It could be concluded that rearing goats in semi-intenssive system my better than village system with some recommendation for good economic benefits from the goat rearing as the following (1) suitable stocking densities on each group housing , similar age, size and group. (2) Group should be kept stable, and the repeated regrouping avoided. (3) Feed space should be sufficient to avoid aggressive behaviour between the animals. (4) Positive daily contact between human and goats should be encouraged to improve the economic gain from our flock.

Key words: Goat, Management, Dominance hierarchy, Behaviour, housing system.
