The number of deaths of guinea fowl during the brooding period accounts for 60% to 70% of the entire rearing period, and its mortality rate will be very high if the rearing and management methods are not appropriate. Therefore, to improve the effect of brooding and reduce the mortality rate during the brooding period, the following measures should be taken:
1. Therefore, it is important to make sure that the chicks drink the first water after coming out of the shell at the first time after entering the farm, i.e. "open water". For chicks that do not know how to drink and cannot find a water trough, they need to be fed water manually. The quality of the "open water" has a great impact on the survival rate of the chicks.
The "food start" is to let the chicks take their first bite of food after coming out of their shells, and then learn to find food on their own. Starting too late, not assisting chicks to learn the ability to forage for food, and feeding irregularly will cause chicks to become hungry, affecting their growth and even causing death.
2. Improve the disinfection of brooder house, utensils and bedding
Brooder house: thoroughly clean the dust on the walls and eaves, rinse the walls and the ground with tap water, dry the walls with 20% of the milk of lime, and then use 3% of the alkaline water to brush the ground and the wall 1 meter above the ground, and then close the doors and windows and fumigate the wall with formaldehyde for 24 hours.
Tools: wash the trays and drinkers with water, then soak them in 0.1% Neosporin solution for 1 hour, and finally rinse them with water and dry them in the sun.
Bedding: dry before use, and 1/500 ~ 1/600 of 84 disinfectant solution spray disinfection.
3. Give the right temperature and humidity
Breeding temperature is the key to the success of brooding, 1 ~ 2 days of age for the appropriate temperature of 32 ℃, and can be reduced by 0.5 ℃ every day. Although the British toffee chickens are more resistant to cold, but in the 21-30 days of age to ensure that the room temperature of about 22 ℃, so the brooder house should be equipped with adequate heating equipment, such as iron stove with smoke pipe, heat preservation umbrella or electric heating plate and so on. In addition, good control of flock density, ventilation conditions, seasonal factors, can be better control of the temperature, to reduce the temperature stress caused by disease and death.
Relative humidity of 65% to 70% in the early stage, 55% to 60% in the late stage is appropriate. The brooder house should be strictly prevented from the intrusion of wind, and in good weather or chicken activities to open the window for a period of time in order to change the air.
4. Give full-price feed and clean water
Full-price egg chick meal can be fed, and mixed with 4% of imported fishmeal and 6% of feed yeast, so that the feed crude protein reaches 25% or so, in order to facilitate the growth and development of chicks. Feed the chicks all day long, but be careful to feed them more and more frequently. Drinking water is best used with clean cold boiled water.
5. Strengthen management, control disease
With the increase of age, the feeding density should be gradually reduced from about 60 per square meter to about 30 per square meter. Pay attention to hygiene, wash the material tray and drinking vessel diligently, and replace the wet and dirty bedding in time. Observe carefully, prevent and control the disease, and keep good records. Feeders should carefully observe the chicks' spirit, appetite, feces and respiratory conditions every day.
Diseased and weak chickens should be isolated and treated in a timely manner; dead chickens should be dissected and diagnosed in a timely manner, and the right medicine should be prescribed. Regular disinfection, vaccination in strict accordance with the immunization program and do a good job of recording various forms.
