Muscovy ducks are popular among consumers because of their high lean meat percentage and strong game quality. The demand of the market has promoted the rapid development of Muscovy duck production. Now we will introduce the main points of feeding and management techniques for Muscovy ducks as follows: 1. First, choose ducklings. According to the different colors of the Muscovy duck, there are white Muscovy ducks, black Muscovy ducks and black and white Muscovy Duck. In the procurement of ducklings, according to the use of the product, such as for the factory processing or separation should choose white Muscovy duck, such as live ducks should be selected black Muscovy duck or black and white Muscovy duck. At the same time, in order to ensure the quality of ducklings, they should be purchased as much as possible from the breeding duck farms that hold the “Production Permit for Breeding of Livestock and Poultryâ€. Second, ducklings feeding and management. Generally from hatching to 3 weeks old ducklings. Insulation. In winter and spring, the temperature is relatively low. Infrared lamps are commonly used for raising brood breeders. In general, 250-watt infrared lamps can hold 100-200 ducks per pod. Room temperature control standards are: 28°C in the first week, 25°C in the second week, and 22°C in the third week. illumination. The hatched ducklings need day and night illumination in three days. If the brooding room lacks of light, use electric lights to supplement the light. After three days, the illumination time can be gradually reduced. However, there is a rodent damage. The lamp should be illuminated overnight (usually a 15-25W bulb) to prevent the mice from attacking the ducklings. Drinking water. The ducklings drink water after 24 hours of hatching and then eat. Muscovy ducks should be fed with water from a glass bottle to prevent wet duck feathers. The feeding time should not be too short, and deeper feeding can be selected. 1-3 weeks old ducklings general feed formula: corn 40%, 40% powder 20%, bran 5%, fine 10%, soybean cake 17%, fish meal 6%, minerals and vitamins amount. Third, the feeding and management of ducklings. Usually 4-7 weeks old ducklings. At this stage, the duck grows fastest and its food intake increases greatly. In particular, animal feed is preferred and the feed can be refined and thickened. The general feed formulation is: corn 50%, No. 4 flour 14%, bran 7%, fine sorghum 10%, bean cake 14%, fishmeal 4%, minerals and vitamins. Most specialized households adopt captive breeding methods, but there are also grazing and feeding materials. Even if they are kept in captivity, generally duck ponds have river ponds for ducks to play with. Muscovy ducks do not change their hair and are especially afraid of heat. Therefore, attention should be paid to the ventilation and coolness of duck houses in summer and autumn. Fourth, feeding and management of fattening period. Muscovy duck fattening time should be determined based on individual differences and the speed of growth and development, too early will affect the normal development, too late will reduce the feed conversion rate. The fattening is generally started at 50-60 days, and the fattening period is 20-30 days. It is sold when subcutaneous and intra-abdominal fat deposits are formed. During this period, properly increase the proportion of energy feeds to keep a quiet, dry and clean environment to promote duck fattening and feather neatness, which is conducive to sales.
