Commercial production of table duckling commenced about the beginning of the 20th century and by 1950 (Scott and Dean, 1991) there were more than 40 commercial duck farms located on Long Island. In 1953 the Long Island Duck Growers Marketing Cooperative provided finance for construction of a Duck Research Laboratory at Eastport, Long Island. Research was jointly undertaken by Cornell University and the Long Island Research Cooperative and contributed significantly to growth and development of the duck industry worldwide.
Ducks obtained most of their food from the duck pond. Such small-scale domestic duck keeping, making use of a pond or a river, can still be found in Europe and in many other countries around the world. However, commercial duck production in Europe and North America generally makes no use of scavenging: all food used in the enterprise has to be bought and paid for. Feed conversion ratio is therefore the most important single index of success for duck production when using a fully housed system. 4).
Only essential personnel should be allowed access to brooding and rearing accommodation. Everyone should wear protective clothing and footwear and wash their hands prior to entry. 44 Chapter 3 Litter materials such as green wood shavings and sawdust, rice hulls and chopped straw often contain more than 12% moisture on delivery. However, spreading litter and supplying both heat and ventilation for about 24 h will reduce litter moisture content to about 3%, an essential prerequisite for providing day-old ducks with a warm, dry and comfortable bed.
