ABSTRACT
TRIANA SUSANTI. The Relationship Between Molting and Egg Production
Genetically on Crossbred Alabio and Peking Duck. Under direction of RONNY
R. NOOR, PENI S. HARDJOSWORO, and L. HARDI PRASETYO.
Molting is a natural phenomenon on all adult female birds related to egg
production, but the extent of its effects on egg production has not been known. An
experiment was conducted to study the nature of the genetic relationship between
molting and egg production, to study the effect of the prolactin hormone
concentration on the molting and egg production, and to get an alternative way
of controlling the molting in ducks. The research materials were crossbred Alabio
and Peking ducks i.e AP ( Alabio ♂ x Peking ♀) and PA (Peking ♂ x Alabio ♀),
10 males and 90 females, respectively, with the total number of 200 birds. The
variables measured were the pattern of molting, frequency, starting time of
molting, duration of stops laying eggs, and the prolactin hormone concentrations
that were associated with the production of eggs for 48 weeks. The results showed
that the mechanism of molting always started with a stop laying, molting, and
laying back. The molting occurence was used to divide the experimental ducks
into two , namely (a) the ducks showing no molting during 48-weeks observation
and (b) ducks showing molting during 48-weeks observation. The average egg
production for 48 weeks in the non-molting ducks were significantly higher than
that in the molting ducks (P
