The Application Of Unconventional Feed In The Duck Diets

In order to provide a scientific basis for applications of some different protein diets in actual production, the single factor experiment was performed to determine the effects of different dietary treatments with different levels on growth performance and carcass-quality of Cherry Valley Duck SM3 throughout the starter, grower and finisher phases of growth.Results showed that the feed intake (growing, finishing and entire growth periods) and feed conversion rate (finishing and entire growth periods) of ducks significantly increased (P<0.05) with the addition of 10%, 15% and 15% cottonseed meals at the starter, grower and finisher phases, respectively. There were no significant effects on the body weight gain, body weight and carcass-quality (P>0.05). In present studies, the recommended appropriate content of cottonseed meal in ducks (Cherry Valley Duck SM3) diets should be within 10%.The growth performance of ducks were significantly affected by supplemented with 10%, 15% and 15% corn germ meal at the starter, grower and finisher phases, respectively. Weight gain, body weight and feed efficiency of ducks fed corn germ meal were significantly increased in any growth cycle (P<0.05). Body weight significantly decreased of growing ducks (28-day-old) with the addition of 15% cottonseed meals. Growth performance and carcass characteristics of ducks were not affected by feeding 15% cottonseed meals at finisher phases.In this trial, we studied the effects of DDGS coming from different places on the performance of ducks. Results showed that supplementation of 10%, 20% and 25% DDGS at the starter, grower and finisher phases respectively did not affect growth performance of ducks (P>0.05), wherever the DDGS come from China or USA.Results showed that the performance of ducks were not affected with the addition of 10%, 20% and 20% rice bran meal at the starter, grower and finisher phases, respectively.
