Two cereals (corn and sorghum) per two lipids sources (vegetable-oil and beef-fat) were used to formulate four different feed for mule ducks. Two hundred and thirty four mule ducks were reared in outside pens from 29 days and were slaughtered at 63 days old. Live weight, feed conversion efficiency, slaughtering traits, tigh-drumstick meat/bone ratio, skin with subcutaneous fat, colour of skin and meat, water holding capacity, and meat cooking loss for roasting at 70° and 90° C were measured. The results showed that: sorghum reduced live weight but improved conversion efficiency; animal fat improved the carcass aspect but increased incidence of the skin and decreased the live weight.

Abstract
Two cereals (corn and sorghum) per two lipids sources (vegetable-oil and beef-fat) were used to formulate four different feed for mule ducks. Two hundred and thirty four mule ducks were reared in outside pens from 29 days and were slaughtered at 63 days old. Live weight, feed conversion efficiency, slaughtering traits, tigh-drumstick meat/bone ratio, skin with subcutaneous fat, colour of skin and meat, water holding capacity, and meat cooking loss for roasting at 70° and 90° C were measured. The results showed that: sorghum reduced live weight but improved conversion efficiency; animal fat improved the carcass aspect but increased incidence of the skin and decreased the live weight.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
