Abstract |
Social relationships of 30 N'dama cows during supplementary feeding, post-grazing, were studied over a period of 1.5 years. Dominance ranks determined during idling and feeding periods were strongly correlated (Spearman's rank correlation (rs = 0.964, P < 0.01). The number of animals dominated by a cow during feeding was strongly (P < 0.01) related to liveweight (r = 0.822) and age (r = 0.755). Low status cows ate less frequently than medium and high status animals, while middle ranking cows were ejected more frequently from the feed trough than other dominance groups. Animals had preferences in the use of feed troughs, with social rank being the dominant factor determining the location of feed trough space used. Cows of similar status were generally preferred feeding and movement neighbours and antagonists. However, the dominance rank of an animal and its preferred neighbour during idling were not significantly correlated (rs = 0.220, P > 0.05). Voluntary leadership ranks into and out of the pen were, respectively, related closely (P < 0.01) to feeding dominance ranks (rs = 0.661, 0.640) and idling dominance ranks (rs = 0.621, 0.669). |

Abstract |
Social-related behaviour of N'dama and West African Shorthorn (WASH) cattle grazing together was studied over 10 consecutive days. Dominance was not related to age, liveweight or leadership when the animals were led into a weighing scale or into and out of the experimental paddock. Dominance had no influence on the use of shade, on drinking frequency or on grazing time, it was, however, positively associated with time spent ruminating and idling and with the frequency of allogrooming. Forced leadership into a weighing scale was negatively correlated (Spearmans rank correlation (rs=-0.69, P<0.05) with liveweight while voluntary leadership, out of the experimental paddock (rs=0.85, P<0.01) and into the experimental paddock (rs=0.76, P<0.05), was positively correlated with liveweight. Voluntary leadership also positively and significantly (P<0.01) influenced the frequency of visits to the water trough. All measures of leadership were significantly but negatively correlated with frequency of social association (close contact) between cows. N'dama were more aggressive than WASH and had higher dominance values. There was a slight tendency for WASH to associate more with their peers than N'dama with their peers. Social behaviours such as allogrooming were low and rubbing and sniffing absent in both breeds. |
