Chicken rearing:
Before the chicks start eating, they drink once with 4/10,000 potassium permanganate solution to disinfect and excrete the meconium and clear the intestinal tract. The young chicks eat for the first time and the young chicks eat for the first time. They are fed with chick pellet feed and begin to feed five to six times per day. For chickens with weaker constitution, they should be fed once in the dark, and then gradually feed three to four times/ day.
Chicken nutrient indicators:
Crude protein 18-19%; Energy 2900 kcal/kg; Crude fiber 3-5%; Crude fat 2.5%; Calcium 1--1.1%; Phosphorus 0.45%; Methionine 0.45%; Lysine 1.05%. The amount of material used for chicks should be based on actual feeding conditions. Chick feeding must be done regularly, quantitatively, qualitatively, and keep drinking water clean.
Brooding temperature:
The temperature has a great influence on the growth and development of the chicks, so the temperature of the brooding must be strictly controlled. Brooding temperature to grasp such a basic principle, the early brooding temperature should be high, weak brooding brooding temperature should be slightly higher, small groups feeding higher than the large group raising, nighttime higher than the day, cloudy days than sunny days.
Brood Humidity:
If the indoor air humidity is too high, harmful microorganisms will multiply and affect the healthy development of the chicks; therefore, the humidity in the brooding room should be maintained at 65-70%.
Maintain normal ventilation:
The carbon dioxide content in the brooding house should be controlled at 0.2% and should not exceed 0.5%. The content of ammonia gas should be less than 10ppm and should not exceed 20ppm. The content of H2S should be 6.6ppm and should not exceed 15ppm. When ventilating and ventilating, it is necessary to prevent chicks from catching colds. It is required to improve the room temperature for brooding before ventilating. The ventilation time is best chosen around noon. Ventilation and ventilation should be performed slowly.
Broken down:
Chick breaking time is generally 7-10 days to order, in order to prevent stress, before and after the break in the drinking water or feed plus Vk4 (4mg/kg) or plus electrolytic multidimensional.
Chicken immunity:
In order to prevent the occurrence of various infectious diseases in chickens, the immunization work of Malik, Newcastle disease, infectious bursa, infectious bronchitis, laryngotracheitis and fowlpox should be done according to the chicken immunization program provided by the breeding farm.
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.
