Feed containing black soldier fly larvae for improving growth performance of meat ducks

Abstract

The invention relates to the technical field of livestock feed, and particularly discloses feed containing black soldier fly larvae for improving the growth performance of meat ducks. The feed comprises, in weight percent, 50-70% of corns, 1-12% of bean pulp, 20-45% of accessory components, 1.2-1.4% of stone powder, 0.2-0.5% of calcium bicarbonate, 0.1-0.5% of sodium chloride, 0.1-0.2% of methionine, 0.2-0.6% of lysine, 0.02-0.03% of threonine, 0.03-0.05% of choline chloride, 0-0.01% of 2% yellow pigments and 0.4% of premix. Dried black soldier fly larvae accounting for 1%-3% of the total weight of basic raw materials are added on the basis. As dried black soldier fly larvae powder is added, the growth performance of the meat ducks can be promoted by active nutrient substances, feather quality is improved, eccentricities such as feather picking and vent pecking are decreased, the immune and healthy state of the meat ducks is maintained, and various diseases under intensive cultivationconditions are decreased.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry feeds, and particularly relates to a feed containing black soldier flies for improving the growth performance of meat ducks. Background technique [0002] Meat duck has the characteristics of resistance to rough feeding, short growth cycle, fast growth rate, high proportion of breast and leg meat, and delicious muscle flavor. It is an important part of my country's poultry meat consumption. At present, with the improvement of residents' requirements for meat quality and the increasingly fierce market competition, how to increase the market weight of commercial ducks, reduce feeding costs and improve the carcass quality of meat ducks has become a problem that duck farming enterprises are currently concerned about. In addition, the feather quality of meat ducks, including fullness, uniformity, wing length and gloss, also affects the time to market and breeding income of meat ducks. Th...
