Growth performance and meat production of fattened paddy-herded ducks fed fish silage mixed diets

Issue Date

Abstract

The growth performance and carcass characteristics of fattened paddy herded ducks were investigated. The ducks were fed agro by-products, namely, fish silage, tofu cake and sweet potato which constituted up to 50% of the diet. The dry matter intake and daily gain of Cherry Valley ducks tended to be higher than those of the Aigamo ducks during the brooding period while the daily gain of the Cherry Valley ducks was higher than that of the Aigamo ducks during a paddy grazing period of 56 d and appeared to be superior in paddy herding condition. Both breeds fattened with diets containing agro by-products showed comparable growth performance to the reference diet.

The dressing percentage, meat yield and carcass meat of ducks fed agro by-products tended to be better than those of the ducks fed the reference diet. The crude protein and moisture content of the breast meat of Cherry Vallet ducks fed agro by-products such as fish silage and tofu cake were significantly higher than those of ducks fed the reference diet. There was a tendency for amino acids to increase in both the thigh and breast meat of both breeds given fish-silage-based diets. This proved that the paddy herded ducks can adapt well to fish silage mixed diets without adverse effects on their growth performance and carcass quality.
