Feeding Techniques for Meat Ducks under Stress
1, improve nutrition
Feed intake of meat ducks declines with rising temperatures, so diet formulas should be adjusted in summer and autumn to ensure the growth of meat ducks. In the summer of 2000, the author reduced the protein level in the diet to 14.5%, and added fat and 2% rapeseed oil to increase the energy level in the diet, on the premise that the essential amino acids were able to meet the basic needs of the duck. The energy level was 1.31 MJ/KG. , increase the content of cellulose 7%, while increasing the vitamin content, VA, VD, VC, VE is 2 times the normal amount of added, ducks grow well, no abnormalities occur.
2, create a comfortable environment
In summer and autumn seasons, in order to reduce stress, we should pay attention to ventilation and convenient water supply when designing houses or building greenhouses; greenhouses should be protected from sunlight; indoor flat-mesh culture, ventilation windows should be built around duck houses to ensure air convection and high temperatures. Fans should be installed; according to the size of the flat screen, the number of ducks should be reasonably stocked (5/m2 at 4-6 weeks old).
3, to prevent stress
At present, most farmers purchase feeds from the market and can only know their nutrient content from the production label. This requires farmers to strengthen the observation of ducks and find that abnormal phenomena such as feathers have to be taken in time. Countermeasures.
1. When faced with high temperature, sudden change of weather, reloading, etc., Vc should be added to the feed at 100 mg/kg and 50 mg/kg VE, which is an effective measure to reduce stress damage. Feeding fresh vegetables can increase the intake of vitamins and cellulose in ducks, and can also effectively prevent ducks from feathering. It has been recommended that four farmers in the summer and autumn seasons, ducks be fed with 4% malt after three weeks of growth. Rice sprouts are very good at preventing the occurrence of stress such as pecking feathers.
2. For ducks that have found feathers, add 0.4% methionine to the feed and feed for 3 days. If the duck eats the feathers of the cockroach, you can consider adding 1% raw gypsum powder, but it is rough in the diet. If the fiber content is too low, feathering may also occur. Specific analysis is required. Breaking crucibles is an effective measure, but since it will have an impact on growth, it is generally not used unless it is a large number of ducks.
