| Descripción: | In order to investigate the effects of oestrus on milk yield and composition in camel (Camelus dromedarius) reared in oasis intensive system in southern Tunisia, 8 healthy females Maghrebi camels (age: 10.6 ± 2.9 years, body weight: 505 ± 39 kg and day in milk: 275 ± 18 days) were equitably divided in two groups. Each female in group 1 received 5 ml of Receptal (20 µg Buserelin; GnRH analogue) to induce oestrus while dams in group 2 were not injected and served as control. Females were monitored during morning milking for the following 15 days, to record oestrus behaviour, œstradiol-17β levels, milk yield, estimated daily milk, lag-time, time of milking, titrable acidity and density of raw and 24 h conserved milk, somatic cell count (SCC) and milk’s major components (dry matter, fat, protein and ashes). Our results suggest that oestrus did not affect (P>0.05) production and physicochemical parameters in milk and did not alter milk conserved in 4°C during 24 h. These data indicate that changes in physiological status of dairy camels during the breeding season do not require alternative measures to guarantee milk quality. |
