First, to see the appetite: When feeding, as long as the ducks are quickly gathered, indicating that the appetite is very strong, you can feed more properly, if the duck food bulging, when feeding is not set, you can feed less. Second, look at feathers: feathers bright, close, indicating that the feed properly. If the feathers are loose, the wings are hanging down, walking is weak, and you don't want to splash, you should add green feed in time. Third, look leisurely: The ducks panic into the water, climbed ashore wings drooping, trembling body is a sign of falling eggs, should be fed fine material. Fourth, see the feces: If the feces are all white, indicating that the animal feed too much food, poor digestion and absorption, fecal loose; white not much, indicating that feeding animal feed more reasonable. V. Look at the production of eggs: Ducks produce eggs between 2 and 8 o'clock in the morning, indicating proper feeding. If the time for laying eggs is delayed and getting smaller, there will often be production stoppages. Sixth, look at the egg shape: egg-shaped ducks for the food and poultry, the larger end of the egg is less early food, the small end of the egg is less than the food. Seven, look at the eggshell: If the shell is thin, there is trachoma or rough, soft shell, indicating lack of calcium, we must promptly add shell powder, calcium phosphate, lime powder and bone meal. Eight, to see the weight of eggs: enough water, duck fat, egg-shaped round and large, 14 eggs weighing about 1,000 grams, water shortage, 17 to 18 eggs weighs about 1000 grams, this time, pay attention to feed water. Nine, to see the weight of the duck: After the duck has laid eggs for a period of time, the weight still maintains the original level, indicating that the materials used are reasonable. If the duck's weight is decreased, it shows that the nutrition is insufficient; if the duck is too fat, it is the cause of excessive energy. X. Look at the spirit: Healthy, productive ducks are spirited and flexible. If they are restless and unresponsive, they indicate that the ducks are weak or sick.
