  • Title: Comparative performance of intensively managed Khaki Campbell and native Indonesian ducks.
    Author: Hetzel DJ.
    Journal: Trop Anim Health Prod; 1984 Feb; 16(1):39-46. PubMed ID: 6730004.
    Abstract:
    Egg Production traits of Khaki Campbell, Alabio, Bali and Tegal ducks were measured to 68 weeks of age under intensive management. Khaki Campbell ducks laid significantly more eggs and required less feed per egg or per gram of egg produced than the Indonesian breeds. Appreciable numbers of local ducks were observed to moult on two occasions during the trial. It was thought that this may have been a response to seasonal factors such as rainfall patterns. Tegal ducks laid significantly fewer eggs and were less efficient than Alabio and Bali ducks. Egg specific gravity was consistently highest in the Alabio and Tegal breeds. The poor production of Tegal ducks compared with that in other studies may have been related to their early onset of lay under the 16 h daylength used in the trial or to a sampling effect.
