Genotype x Nutrition Interactions in Growth and Laying Performance of Ducks

(Indonesia), Doctor of Philosophy in Animal Science (University of the Philippines Los Baños)

Dissertation Abstract:

Two independent experiments were conducted to evaluate the effects of breed, plane of nutrition, and breed x plane of nutrition interactions on the performance of a meat-type Mallard Pekin (Anas platyrhynchos), Muscovy (Cairina moschata), and egg-type Mallard (Anas platyrynchos) under low and high planes of nutrition.

Muscovy gave consistently higher body weight gain and carcass plane of nutrition gained more weight and had better feed efficiency. Significant breed x plane of nutrition interactions in body weight gain and feed efficiency of ducks were observed in both periods.

Under high plane of nutrition, egg production during the first and until the third month was highest in Mallard and lowest in Muscovy. Pekin laid bigger eggs but consumed more feed than the Mallard. At both planes of nutrition, Muscovy consistently and significantly consumed feed least efficiently but laid eggs with the highest average weight.

Significant (P<0.05) breed x plane of nutrition interaction in feed efficiency was observed in both growing and laying periods.

This study showed that the comparative performance of the three breed of ducks differed under high and low planes of nutrition during the growing and laying periods.
