Ducks may be grown on dry mash, a combination of dry and wet mash or pellets. Ducks prefer wet mash due to difficulties in swallowing dry mash. The pellet feeding, though slightly costly, has distinct advantages such as saving in amount of feed, minimum wastages, saving in lobour, convenience and improvement in sanitary conditions. Ducks are good foragers. The use of range, pond or supplementary green feed, reduces the feed cost. DUCKS SHOULD NEVER HAVE ACCESS TO FEED WITHOUT WATER. During the first eight weeks, birds should always have access to feed, but later on they may be. | Soybean Meal An Excellent Protein Source for Poultry Feeds Darwin G. Britzman Ph.D. I. Soybean Meal-An Ideal Protein Source for Poultry Soybeans have been used as a protein amino acid source in human diets for more than 5000 years. In the early 1900 s soybeans were introduced into the United States primarily for their oil content. It was eventually discovered that the meal by-product was a valuable ingredient for livestock and poultry when it was properly processed. As early as 1917 it was demonstrated that raw soybeans fed to rats were nutritionally inferior to properly heated soybeans. Since that time soybean meal has become the most important source of protein for poultry and other livestock throughout the world. It is the standard against which other protein sources are compared. It has also become the protein source that determines the price of proteins for livestock feeding throughout the world. Soybean production increased globally by 4 017 141 metric tons per year from 1988 to 1998. In 1998 one hundred fifty seven million metric tons of soybeans were produced in the world. Soybean meal production in 1998 was 101 million metric tons. In the United States soybean meal is the primary source of supplemental protein in poultry swine and other livestock diets. In 1998 13.28 million metric tons of soybean meal were used in poultry diets. In many of the feed formulas for poultry and swine soybean meal is the only source of supplemental protein. Poultry consume 52.9 of the soybean meal utilized in the United States. Soybean meal is an excellent choice as a supplemental protein source for poultry for a number of reasons including the following 1. Soybean meal contains a high level of protein in comparison to other plant protein sources. 44 with hulls 46.5 to 50 without hulls 2.
