I. Drinking water management
Except for the need to control water due to medication or vaccination, the normal 24-hour water supply should be ensured. To ensure adequate drinking water supply, chicken farms should arrange special time and personnel to overhaul the water line. The chicken house keeper should check the water line daily for blockages and nipple drinker leaks. Clogged water lines cause water shortages in broilers, with very serious consequences.
And the water that comes out of a leaking nipple drinker not only wastes medication, but also enters the catch pan to dilute the manure that will eventually flow into the trough, which is a waste of feed and may cause intestinal diseases. These two problems are problems that every chicken farm will encounter, early detection and early maintenance is very important.
In addition, before the drinking water immunization to thoroughly clean the water dispenser to ensure that no disinfectant residue in the drinking water.
2.Hygiene and disinfection management
Do a good job of environmental health and disinfection inside and outside the chicken house, cut off the path of pathogen transmission, all staff without special circumstances is strictly prohibited from leaving the field, return to the field by changing disinfection before entering the production area. Remove chicken manure in a timely manner. Whether it is manual manure removal or mechanical manure removal, the manure should be cleared regularly to minimize the residence time of chicken manure in the chicken coop.
Especially in the first few days of brooding, there is usually no ventilation in the chicken coop, and the manure should be removed in time every day depending on how much it is produced. As broilers grow up, manure should also be removed regularly.
Regular disinfection with chicken spray is an important means of preventing and controlling the occurrence of infectious diseases. Disinfection with chickens should be done with odorless and less irritating disinfectants and several ingredients should be used alternately in rotation.
In general, 1 time a week in winter, 2 times a week in spring and autumn, and 1 time a day in summer. One point to note here is that disinfectant water should be used after the coop has been pre-warmed. The disinfection effect is best when the room temperature is around 25℃. The purpose of disinfection is mainly to kill airborne bacteria and viruses, so the finer the sprayed droplets are, the better, do not understand that spraying on chickens is disinfection.
3. Temperature management
The highest level of temperature management is “constant and smooth transition”, sudden cold and hot is the big taboo of chicken farming. The right temperature is the guarantee of fast growth of chickens, and generally the temperature is relatively high, the growth will be faster.
According to the physiological characteristics of chicks, the first 3 days of brooding temperature should reach 33 ~ 35 ℃, 4 ~ 7 days a day to drop 1 ℃, 29 ~ 31 ℃ at the end of the week, after the weekly drop of 2 ~ 3 ℃, 6 weeks of age down to 18 ~ 24 ℃ can be. Cooling must be carried out slowly, and according to the chick’s constitution, body weight, seasonal changes to decide, pay attention not to make the temperature in the house drastic changes.
Whether the temperature is appropriate, in addition to observing the thermometer (thermometer should be hung in the brooder at the same height as the back of the chicks. Do not put it too close to the heat source or in the corners), it is more important to measure the performance, dynamics and sound of the chicks. Although you can usually use a thermometer to detect the temperature in the chicken house, the thermometer sometimes fails and it is incorrect to rely entirely on the thermometer to judge the temperature.
The breeder should master the method of watching the chickens apply temperature and learn to judge the suitability of the chicken coop temperature without using a thermometer. If the chicks are evenly distributed and a few of the whole flock or individual larger chickens appear to open their mouths, it means that the temperature is normal. If the chicks appear to open their mouths and wings, move away from the heat source and crowd to the side, it means the temperature is over.
When they appear to pile up, lean towards the heat source, crowd together or pile up in the east or west, it means that the temperature is too low. Summer chickens to prevent heat stroke, especially after 30 days of flocks, timely activation of the wet curtain is very important, the ambient temperature exceeds 33 ℃ when the water spray cooling equipment must be available. Note also that at night the chicks are in a sleeping state, resting without moving, the required temperature should be 1 to 2 ℃ higher.
