First, excellent varieties. The meat ducks with excellent varieties have high genetic potential, high growth rate, strong disease resistance, and high utilization rate of feed. At the same age, they consume the same amount of feed and their weight gain is higher than that of other varieties. The duck is much bigger. Second, the temperature control. The suitable growth temperature for meat ducks is generally between 12°C and 24°C. The feed can be used effectively in this temperature range. Therefore, it is necessary to create conditions as much as possible, such as winter shelters, summer shady shade, and other measures to increase the feed remuneration through insulation and cooling. Third, the diet should be balanced. The proportion of protein and energy in the meat duck's feed must be balanced, and the energy value in the feed should be appropriate. When the energy value is too high, the consumption of feed increases, resulting in the waste of some nutrients. Fourth, feed should be fresh. One is that the raw materials should be fresh, and the second is that the feed should be stored in a ventilated and dry place, and a moisture-proof material should be placed between the ground and the ground. Mixing materials should be used up as soon as possible, diligently and frequently fed to prevent compaction and mildew. Mildew feeds are likely to cause poisoning in meat ducks, pull maggots, etc., thereby reducing feed utilization. Fifth, timely slaughter. Meat ducks are generally suitable for slaughter at 40-48 days, because meat ducks gain weight and feed rewards have peaked. After 50 days of age, weight gain of ducks has decreased, and feed rewards have decreased. Six, the rational use of additives. Nutrients such as minerals, vitamins, and amino acids are necessary, and other non-nutrient additives are also helpful in increasing the growth rate and feed utilization of meat ducks. Bacillus peptide zinc, oxytetracycline, furazolidone, olaquindox and other antibacterial growth-promoting agents have a significant effect on increasing meat weight gain and feed utilization. ※
