Winter Broiler Breeding Management Five Measures
Winter is the most difficult season for broiler breeding. Because of the contradiction between ventilation and heat preservation in winter, due to the high stocking density, it is too closed and insulated, resulting in too many CO2 in the house and lack of fresh air. This makes the climate inside the house very poor, thus inducing many kinds of Diseases such as E. coli disease, respiratory disease, ascites etc. Therefore, raising broilers in winter should be managed from the following aspects. 1. Decrease the stocking density: In the closed chicken house, the O2 content in the home is reduced due to the respiration of the flock and the CO2 is increased. In the chicken house where heating measures are taken, the humidity is high, the temperature is high, the immunity of the chicken body is reduced, and the prevalence is increased. Due to the intensive breeding, the chances of pathogens passing through the air increase, and chickens have an increased chance of suffering from infectious rhinitis, infectious laryngotracheitis, chronic respiratory disease, and fowl cholera. If the stocking density is reduced, the chickens will be reduced, the oxygen demand will be reduced, the exhaled CO2 will be reduced, and the air pollution index will be reduced, thus reducing the incidence rate. 2, to strengthen the ventilation of the henhouse: When the keeper enters the hen house feels pungent, glare or mild breathing difficulties, must increase the temperature, and slow ventilation, to avoid excessive ventilation, resulting in a partial or entire chicken house temperature Cooling is too fast; cold air should be blown directly to the chicken to prevent the chicken from catching a cold. When the outside air temperature is too low, the ventilation of the house can be preheated in a warm empty room and then passed into the house or the heated air can be sent to the house through a duct or a long cloth bag. Under normal circumstances, ventilation should be carried out in sunny and windless mornings from 10:00 to 3:00, so that ventilation is not easy to make the temperature drop too much, which is also conducive to saving fuel. But at any time, if there is pungency, harsh gas or breathing, it is necessary to ventilate, keep the air in the house fresh, and reduce the incidence of chicken disease. 3, control of chicken house temperature: temperature is the primary condition for the normal growth and development of broilers, and broiler body temperature regulation, activities, feeding, drinking water, feed digestion, absorption, disease resistance, etc. are closely related. The optimum temperature for different growth stages is different. Under normal circumstances, the brooding temperature is 33-35°C, and the weekly temperature changes can drop by 2-3°C until 18-21°C. When brooding, we must master the temperature standards, not too much too low; to a balanced and stable, the early growth period is high late low, gradually reduced, must not flicker, change too much. The basic principle of temperature control is higher in the early period than in the later period. The nighttime is slightly higher than that in the daytime. The weaker chicks are higher than the strong chicks. The cool winds, the snow and snow days are higher than normal sunny days, and the winter and spring brooding is higher than the summer and brooding brooding. Before and after the immunization and the chicks During the illness, it is higher than usual. 4. Control the humidity of the broiler house: The most suitable humidity in the broiler house is 60%-70%, the humidity in the house is too low, the broiler shows sluggish performance, feathers are messy, the skin is dry, the palatines and claws are dull and the chicken body is easily dehydrated. Cause chicken respiratory diseases. If the humidity in the house is too high, the heat emitted by the chicken body will increase, making the chicken colder. The production may take a water basin on the heat source, increase the humidity, or humidify with a humidifier; take the enhanced ventilation and place the lime block indoors. Other ways to reduce the humidity within the home. At a temperature of 33°C, the wet-table temperature should be 28-29 degrees, which is a 4-5 degree difference between dry and wet temperatures. This will ensure 65%-70% relative humidity in the house. 5, to do a good job of sanitation: the house should be cleaned every day, timely removal of feces and litter, to prevent long-term storage of fecal urine produced large amounts of NH3, resulting in ammonia poisoning. After the broiler is slaughtered, it is necessary to thoroughly sterilize the chicken house and empty it for 10 days before entering the chicken. The surrounding environment of the chicken house is disinfected once a week. Chickens are sprayed and disinfected one to two times a week. Disinfection of feeders and other utensils is regularly performed. In short, rationally arrange the daily life of chickens, strengthen feeding and management, and resolutely avoid the use of mildew feeds to improve the resistance of the chicken body. While ensuring the temperature of the chicken house, use adequate sunshine for adequate ventilation to increase the fresh air in the house. Environmental sanitation, good disinfection work, and reduced stocking density are good for ensuring the health of chickens.
