With the advent of spring, rural farmers have gradually entered the season of brooding chickens. On February 22, the reporter connected Jianzhan Town Animal Husbandry Service Center of Jianshi County and two livestock experts. They reminded the majority of chicken raising specialists that the weather in the spring is volatile, the chickens have weak self-regulating body temperature, and the disease resistance is not strong. Breeders are a little negligent, and it is very easy for a large number of chicks to die. To ensure the survival rate of the chicks, we must take a good "five levels."
1, source off.
The eggs are of uniform size and oval shape. The color is dark yellow or brownish yellow. Before hatching, the eggs should be cleaned and disinfected.
2, density off.
Reasonable breeding density can ensure the health of the flock. The general situation is 30 in the first week per square meter, 25 in the second week, 20 in the third week, 15 in the fourth week, and 10 or so in five or six weeks. During the brooding period, it is best to divide males and females for ease of elimination and management.
3, insulation off.
Brooding temperature: 1 to 18 days, winter temperature is maintained at about 37.8°C, about 37.0°C in summer; 19 to 21 days, winter temperature is maintained at about 37.2°C and summer is 37.0°C.
Degassing temperature (from artificially created temperature environment): 21 to 28 days, the temperature is maintained at about 35.0 °C; 28 to 45 days, 30.0 °C is appropriate; 46 to 60 days, daytime fine weather can be stocked, at night to warm to 25.0 °C.
4, humidity off.
About 1 to 7 days, stay at 55%-60%; 8 to 18 days, stay at 50%-55%; 19-21 days, stay at 60%-70%.
5, prevention of disease.
Chickling with streptomycin or gentamicin after hatching prevents upper respiratory infections. 7-day-olds should be immediately immunized with a "chicken passer" and intranasally immunized. The chicks will equip with 3-5% norfloxacin to prevent gastrointestinal infection within 1 to 2 weeks in a drinking water bucket. % Fluorbenzol prevents red, yellow and red peony.
