In order to avoid problems during brooding, careful preparation should be made before entering the brood. Generally do the following:
(1) Reasonably formulate the production plan: According to the capacity of the chicken house and its own economic conditions, carry out the production positioning, formulate the hatching plan and the annual production plan.
(2) Preparation of the brooding house: The brooding room is required to be dry, have good heat preservation performance, good light and ventilation, and be easy to operate and prevent epidemic prevention. The brooding house should be repaired and circuit safety checked and maintained before the brooding. Rinse, sterilize, and close the doors and windows after drying.
For the brooding room and the surrounding environment of the chicken farm, we must do a good job of rodent control and weed control, and keep the drainage clear.
(3) Equipment and utensils preparation: The normal operation of the thermal insulation equipment is one of the keys to the success of brooding, and other things such as whether the lighting and ventilation equipment are normal, and whether the drinker or the bucket is ready.
(4) Litter Preparation: Litter should be disinfected in advance and dried after being used for ground brooding. Generally, there are wood shavings, sawn wood, and short straws. The litter requires drying, strong water absorption, looseness, no odor, and no mildew. It is better to pave the top if there are dry sands on the ground.
(5) Prepare before entering the chicks.
1 In the first 5 to 6 days before hatching, 20 g of potassium permanganate and 40 ml of formalin were used for the fumigation and disinfection in each cubic meter of chicken house. After 24 hours, the doors and windows were opened for ventilation.
2 Drinking fountains and tanks can be soaked with a freshly prepared potassium permanganate solution or benzalkonium bromide solution, rinsed, and dried before use.
3 Equipped with brooding feed, medicine, and vaccine.
4 Implement good tools, turnover boxes, vehicles, etc.
5 Warming and debugging the day before the hatching to ensure that the temperature of the brooding room meets the brooding requirements.
6 Other equipment preparation: Breakers, syringes, sprayers, droppers, thermometers, buckets, log sheets, etc.
(6) carry young and test chicks. The vehicles carrying the youngster should be kept warm and windproof so that the cold air will not be blown directly onto the chicks. The container for the chickens should be ventilated to prevent chicks from dying of oxygen, and the packing density should be properly controlled to prevent heat. It is better to use special turnaround boxes for chicks.
The key to raising chickens is brooding. The first step in brooding is to “check chicks.†The following are the key points for chicks.
1 Grasp the source of the eggs: The eggs that are provided by the bred chickens of good growth, good traits, good production performance, strong disease resistance, full spirit, and strong metabolism should be selected.
2 to understand the shelling time: the quality of chicks hatched in normal time is better, premature or late hatching chicken is due to improper hatching temperature or poor quality of eggs, it is difficult to raise.
3 If the fertilization rate and hatching rate of the eggs in the batch are high, the quality of the eggs is good, and the quality of the chicks is also good. On the contrary, the quality of the eggs is poor, and the quality of the chicks is also poor.
The mental state of the 4 chicks: The young chicks are lively and loving, their eyes are big and their eyes are divine, their reactions are sensitive, and they are struggling with their strength; weak youngsters and sick youngsters show drowsy, bowed, closed eyes, unresponsive, and struggle in their hands.
5Abdominal condition: The size of the abdomen is moderate, soft, and the umbilicus is well-absorbed. The hairless area is small and covered by the surrounding villi. The weak chicks and “midwifery†youngsters have malabsorption of the umbilicus, blood stains around them, and large hairless areas. Abdominal enlargement, edema, and abnormal color.
6 Anal Area: The anal area of ​​the young and the young is clean, the dry hair is dense and dense; the anus area of ​​the weak and sick area is stained with feces, and the villous moisture is scarce.
