Summer duck nine attention

Posted on

Summer is the prime time for rearing meat ducks, but the high temperature and high humidity environment can make duck house feces rot and ferment, kill pathogenic microorganisms, induce disease, and adversely affect the growth of ducklings. In order to increase the survival rate of summer ducklings, the following nine notes must be observed. 1. Reducing the rearing density The density of ducks per square meter is too large, which will cause crowding, heap pressure and accumulated temperature and turbidity. Therefore, the number of ducks in the circle should be reduced, and additional water basins should be provided. 2. Adjusting the formula of feed The feed formula for ducks at different stages of reproduction differs. The summer feed formula should meet the requirements of all essential amino acids, so that the protein level may be at the minimum, in order to reduce feed digestion heat. 3. Changing Feeding Modes Online raising can reduce the contact between ducklings and feces, reduce the spread of disease, and reduce the incidence rate. At the same time, net raising can reduce the nutrient consumption and heat production of ducks and is conducive to healthy growth. Take the ground duck, it is best not to use thick padding, in particular should not pad straw. 4. Reduce sun exposure Building a high and spacious duck house is an effective way to reduce the impact of sunlight. During the high temperature, water can be sprayed on the roof or sprayed with water, and the top of the house can also be brushed with white ash. 5, optimize the feeding time as far as possible in the early morning and night 8 to 10, feeding more cool time, let the ducks rest during the day. 6, do a good job of daily disinfection Disinfection work to prevent flies, mosquito breeding, so that the duck population from pest harassment. 7. Supply of fresh feed During high temperature and high humidity, the feed is left for too long or the feed in the feed tank is stagnant for too long will cause deterioration of the fermentation. Therefore, fresh feed should be guaranteed. 8, to keep the environment quiet and hot period to avoid sudden scaring, noise interference with ducks in order to minimize the duck's activity. 9. Strengthen prevention and control of epidemic diseases Effective prevention and treatment of duck disease must be done. If diseased ducks are found, they must be treated in a timely manner to ensure proper feeding and management measures.

Laser Distance Meter

Laser distance measure is a very convenient tool for various types of applications in industries, construction and house decoration. Laser distance meter is a very useful device which gives accurate measurement of distance, area and volume especially in large areas such as rooms, apartments, buildings, real estates, factories, warehouses, infrastructures, gardens, roads, and many other applications requiring accurate results for distance , area and volume measurement.

Trade your heavy tape measure for laser rangefinder, which let you simply take measurements with one hand. No matter your job, the laser rangefinder will help you measure much farther, with greater accuracy and in more situations, saving you money and time.
