Late Spring and Early Summer Chicks Breeding Techniques
Beware of climate change
Temperature rises in late spring and early summer, but it is easy to encounter rainy and wet weather. The large temperature difference between day and night has a significant impact on laying hens. Maintaining the proper temperature is the key to the success or failure of brooding. The temperature of the chicken house should be controlled so that the temperature difference between day and night cannot exceed 5 °C. The house brooding room should be built in the house, and the area of the house should be enlarged at any time according to the age of the chicks to increase the oxygen content. The house should be thoroughly cleaned and rinsed with formalin (formaldehyde) and potassium permanganate. For fumigation, close the doors and windows for 12 to 24 hours, then open the doors and windows for ventilation, and clean and disinfect all appliances with 0.2% potassium permanganate solution.
The body temperature regulation function of the chick is not perfect, and it is very sensitive to changes in the ambient temperature, and the ambient temperature has a direct influence on the growth and survival rate of the chick. Before entering the brood, the brooding house must be preheated to meet the brooding temperature requirement. Chickens at 1 week of age require chicken house temperatures of 30°C to 32°C, and then decrements by 2°C to 3°C each week until the shepherd temperature is 21°C, and the temperature is maintained until the brooding is over. The temperature of the brooding room is suitable or not. It can be grasped by observing the performance of the chicks. When the temperature is suitable, the chicks are lively and active, the spirit is strong, the sound of calling is good, the appetite is good, the drinking water is moderate, the feathers are smooth and tidy, and the birds are evenly distributed after rest, and the chicken house is evenly distributed. Extremely quiet; when the temperature is too low, the chicks are slow in action, feathers are fluffy, and the body trembles. They gather under a heat source and scream from time to time. When the temperature is too high, the chicks stay away from heat, they are restless, they breathe openly, and the amount of drinking water increases. The performance of the chicks is severe. Dehydration phenomenon.

Pay attention to ventilation
A reasonable density allows the chicks to feed evenly and keep the chickens in order. The stocking density should be appropriately adjusted according to the chick's age, size, breed, feeding method, season, and structure of the chicken house. The reasonable density of flat-raised chicks ranges from 20 to 25 per square meter from 0 to 4 weeks of age, from 10 to 20 per square meter at 5 to 7 weeks of age, and from 24 to 28 per square meter from 0 to 4 weeks of age. 5 to 7 weeks old 15 to 20 per square meter.
Under normal circumstances, due to the high temperature of the brood chamber before 10 days of age, the relative humidity in the air is often too low, and the relative humidity in the room should be replenished to reach 60 to 65. After 10 days of age, the chicks will gain weight as they grow older. The feed intake, water intake, respiratory capacity, and fecal output are increasing day by day. Coupled with a week-by-week drop in the temperature of the brooding room, it is very likely to cause indoor humidity, and water should be prevented from spilling over the floor or bedding when fresh drinking water is added. On the other hand, the relative humidity of the brooding room is controlled between 55 and 60, that is, 60 to 65% 10 days ago. After 10 days,
55% to 60%.
If there are many drops of water on the top of the brooding chamber and the surrounding brooding chamber of the plastic film, it can be judged that the indoor humidity is high. If people do not smell bad after entering the brooding room and do not feel depressed or depressed, the air is more fresh. On the contrary, the air is dirty and oxygen is insufficient. When the humidity is too high or the air is too dirty, the vent should be opened at the top of the brooding chamber and near the ground to achieve the purpose of ventilation. Ventilation time is best to choose before and after sunny noon, before the ventilation to improve the temperature of the brooding chamber 1 °C ~ 2 °C, ventilation should be carried out slowly, open the doors and windows should be from the end to the end of a half-open state, must not suddenly open the doors and windows Let the cold wind blow directly to the house to make the temperature drop abruptly, and close the door and window when the temperature is kept at the original temperature. More chickens have more air and humidity, and ventilators with high temperatures can be opened for a longer period of time. On the contrary, they should be smaller and shorter. Care should be taken not to allow the chicks to become cold. Take multiple air changes a day to avoid complete ventilation.

Scientific feeding management
Chicks should drink water and eat as early as possible, and make the material and water continue to eat freely. The chicks can be kept in the house first, and the drinking water can be given 1 to 2 hours after the chicks enter the house. The drinking water must be pre-heated. The water temperature is generally close to the temperature (20°C to 22°C). In the first drinking water mixed with 5% glucose for 2 days; the third day in the drinking water with 0.02% to 0.03% potassium permanganate, to enhance the broiler physique to ease the stress response to facilitate the discharge of meconium. After long-distance transportation of chicks, you can add about 5 glucose to drinking water to help eliminate fatigue and restore strength as soon as possible.
The timely start of eating can help the chicks to fully absorb the yolk and excretion of meconium, which is beneficial to the early growth of chicks. Chicks can be eaten 24 to 36 hours after hatching. The feed requires fresh, moderate grain size, easy for chicks, nutritious and easily digestible. Commonly used are shredded corn, millet, broken rice, and crushed wheat. The starter can be boiled until it matures and then fed, which is beneficial to the digestion of the chicks. Feed 5 to 7 times a day, feed 2 to 3 days after feeding the food, and gradually switch to chicks for normal feeding. Feed 4 to 5 times a day. In the fourth day after hatching, some chopped cabbage leaves or young grass leaves may be mixed in the feed. The amount of feed is about 10 or so of the total amount of feed, and then the amount of feed is gradually increased to account for 20 to 30 of the total amount of feed. The 5-day-old chicks can spread the feed on dark background thick paper or plastic cloth, or they can put it in a platter and increase the lighting to induce the chicks to feed freely. After 5 days of age, they can be fed into a feeding trough and keep the height of the trough with the back of the chicken as the chicken grows, so that each chicken has a 2 to 4 cm long slot.
Chicks can be eaten directly with the full price of raw materials, less to add ground, any chicken free to eat. The chicken's digestive function is not yet fully developed. It is necessary to feed a nutritious, easily digestible, full-priced compound feed, and at the same time, feed a suitable amount of green and juicy feed. The use of a single feed or a nutrient-poor feed is not conducive to the growth and development of the chicks. When the full-rate feed is fed at the first week of age, it is fed 6 times a day, the second week of age is fed 5 times a day, the 3rd to 4th weeks of age are 4 times a day, the 5th to 6th weeks of age are 3 times a day, and after the 7th week, it gradually transitions to adulthood. Feed the chicken and reduce the amount of feed. After the first week of stocking, they were fed one at a time in the morning and one in the evening and once in the second week. After the five-week-old chickens with high quality and quick growth, they could be gradually replaced with grains and corn.

Strict prevention and control of diseases
In the spring, the house has less ventilation and less evaporation of water, causing excessive moisture in the house, creating conditions for large numbers of bacteria and parasites. Therefore, the farm must strengthen management, keep the chicken house dry, clean and hygienic, and thoroughly disinfect the house on a regular basis. Peracetic acid is a broad-spectrum and highly efficient chemical disinfectant that is unstable in nature but can release oxygen and acetic acid. Spraying peracetic acid in a chicken house at a suitable time can increase oxygen, disinfect the house, neutralize some of the harmful alkalinity. gas. Oxygenated drugs such as peracetic acid can be sprayed to prevent bacterial diseases, parasitic diseases, etc., so as to avoid unnecessary losses.
According to the actual local selection of a reasonable immunization program to vaccinate, adhere to the prevention of drugs in feed and drinking water, can be added for a long time, "Yi Li Li", adjust the balance of chicken intestinal flora, improve feed conversion, reduce intestinal disease The incidence rate. Some diseases such as ferrets, slow respiratory infections and colibacillosis are transmitted vertically from chicks to chicks and should be prevented in advance. Diseased chickens should be treated in time for isolation and treatment. Dead chickens should be kept away from the burning or deep-buried chicken house.
For chicks that are transported in a long distance or stored for a long time, they should drink 20°C warm water, put brood drugs or multidimensional electrolysis in the water, and control the amount of drinking water to prevent dehydration. Enrofloxacin is added to drinking water from the 2nd to the 7th day of age for the purpose of reducing stress response and preventing diseases during catching, transportation and environmental changes.
