Summer duck "eight want"
Summer is the prime time for rearing meat ducks, but the high temperature and high humidity environment can make the duck manures rot and ferment, breed pathogenic microorganisms, induce epidemic diseases, and adversely affect the growth of ducklings. In order to improve the survival rate of ducklings in summer, we must do the following:
First, to reduce the breeding density of breeding density is too large, will cause duck crowded, heap pressure, plot warm stuffy circle, should reduce the number of ducks in the circle to increase the basin food trough.
Second, we must adjust the formula of feed at different stages of the diet. The formula of feed for ducks varies. Summer feed formula should meet the requirements of all essential amino acids to make the protein level as low as possible, so as to reduce feed heat dissipation.
Third, we must change the rearing mode should be taken to raise the net, can reduce the ducklings and feces contact, reduce the spread of the disease, low incidence, but also can reduce the duck's nutrient consumption and heat production, is conducive to the healthy growth of ducklings. Take the ground duck, it is best not to use thick padding, in particular should not pad straw.
Fourth, to optimize the feeding time as far as possible in the early morning and night 8 to 10 hours, feeding more cool time. Let the ducks rest during the day.
Fifth, to reduce sunlight exposure to build a high and spacious duck house is an effective way to reduce sunlight exposure. During the high temperature, water can be sprayed or sprayed on the roof, and white ash can also be brushed on the roof of the house.
Sixth, to provide fresh feed in the high temperature, high humidity season, the feed is placed too long or feed in the feed tank stagnation will cause fermentation deterioration, should ensure the supply of fresh feed.
Seventh, we must keep the environment in a quiet and hot season to avoid sudden scaring and noise interference with the duck population and minimize the activity of the duck population.
Eighth, it is necessary to do a good job of disinfection and epidemic prevention. Do a good job of disinfection to prevent flies and mosquitoes from breeding and prevent the ducks from being harassed by pests. Effectively prevent and cure duck disease, such as diseased ducks should be symptomatic and timely.
Duck rearing
The seedlings must be selected from duck farms with high production and management levels, strict health and disease prevention systems, good duck breeds, and healthy ducks and disease-free ducks. Do not purchase ducks from duck farms where infectious diseases such as viral hepatitis and duck gizzards have occurred. Miao, ducklings hatched in this duck farm are often infected with these diseases. When purchasing ducklings, we must choose healthy individuals with full spirits, golden yellow feathers, and good umbilical cord healing.
Environment
1. Temperature and Humidity: Ducklings before the age of 3 weeks are not able to adapt to changes in the external environment due to poor thermoregulatory performance. Therefore, suitable temperature should be provided. In the first two days of brooding, the temperature of the brooding chamber should reach 33°C to 35°C, and the temperature should not be lower than 29°C, otherwise it will affect the survival rate of ducks. After 3 days of age, the temperature of the duck house should decrease day by day, and when it reaches 15 days, it should drop to room temperature, generally it should be kept at about 20°C. The humidity in the duck house is appropriate from 50% to 75%. Too dry or too humid is unfavorable to the growth of ducks.
2. Light: Light can promote ducks' feeding and exercise, which is beneficial to the growth of ducks. A large number of tests showed that with 23 hours of light, 1 hour of darkness, the light intensity was 10 lux (lamps 2 to 2, 5 meters above the ground, and there should be 3 watts of illumination per square meter), and better feeding results could be obtained.
3. Adjust the density: generally 1 to 7 days of age on the ground for raising 20 to 25/m2, online brooding 25 to 30/m2; 8 to 14 days of age for raising the ground 10 to 15/m2, online brooding 15 to 20 per square meter; 15 to 21 days of age, 7 to 10 per square meter of flat ground, and 10 to 15 per square meter of online brooding. For medium-yielding ducks, raise 2 to 3 eggs per square meter, and raise 3 to 5 eggs per square meter online.
4. Ventilation. Ducks grow fast, have a strong metabolism, and excrete a lot of waste. Pay special attention to the ventilation of the duck house and keep the air fresh to ensure the healthy growth of the duck.
Lamb meat is popular in ningxia, gansu, qinghai, xinjiang, the hui ethnic areas of the four provinces, all are local characteristics halal cuisine. Mutton "or insufficiency in the warm, fill in beneficial gas, appetizing healthy, beneficial kidney", is to help yuan Yang, it's fill JingXie, beneficial strain, often eat mutton to improve people's physical quality and disease resistance is very good.
