The effective way to improve the production efficiency of laying hens is to increase the survival rate of laying hens, which is also the guarantee of the economic benefit of farmers. When laying hens brood, timely analyze and grasp the reasons for the high rate of death scouring, and take appropriate measures. The cause of the high deadweight rate The high chick slaughter rate is an important factor that affects the breeding of laying hens. The main reason is that there are problems in feeding management. When the rate of death scouring is high, it can be observed through observation that this directly reflects the management quality of the farmer. Normally, the mortality rate of the chicks after 3 days of birth is mainly due to the poor management of the livestock. 1. Brooding equipment is not perfect and temperature regulation is not in place. The key to brood hens is heat preservation. The broilers have weak shells and poor body temperature regulation ability. The surrounding environment directly affects the growth and development of the chicks. If the temperature is rapidly reduced, it can cause diarrhea or colds, and even problems such as getting together and crushed. 2. The level of nutrition in the feed is not enough. Feed singulation, etc. will lead to an increase in the brooding mortality rate. Poor chick malnutrition will seriously affect the future development and production levels, and it is prone to diseases such as chicken pupa, bronchitis, etc., in particular, the immune system is reduced, and severe cases even cause death. 3. Disease prevention. If the disease prevention is not in place, it will lead to an increase in the rate of deaths. If diseases and epidemics are neglected in the breeding process, it will easily lead to the death of the chicks. Therefore, farmers must clearly improve the performance of laying hens. Measures to improve brooding performance The brooding survival rate of more than 96% can be regarded as the standard for brooding, but it is not possible to rely solely on the survival rate to develop high chick quality. When brooding, it is necessary to conduct systematic statistical analysis according to the growth of the flock, take the average value as a reference, strictly measure according to the standard, conduct scientific judgments, and then summarize and improve the brooding method. Feeding control according to standard weight, systematic testing and recording according to different breeds of laying hens, analyzing by weight gain and food intake, and feeding management through the corresponding results, usually performed at around 2:00 PM on weekends. Measure the weight and take the method of sampling and averaging. According to 100 to 200 samples, 2% to 5% of the tested chickens can be collected. Each chicken that is drawn is weighed, so that the value obtained is an ideal result, and then fed according to standard values. Strengthen management during brooding, with particular attention to humidity and density control. In most regions, laying hens are reared on the Internet, and some are on the ground. However, no matter what kind of farming methods, it is necessary to strictly control the rearing density and quantity before brooding. Controlling the rearing density is an essential means to increase the growth of laying hens, and it is also one of the important ways to guarantee future production. Therefore, the culturists need to control the density according to the breeding space. Strengthen the temperature and humidity control is also very necessary, chicken house temperature and humidity have a great influence on the growth rate of layer chickens, in the entire chicken brooding and growth process require proper ventilation, strict control of temperature and humidity, and take seriously the relationship between temperature and humidity, The specific method is as follows: It is recommended that ventilation be carried out when the weather is good, and the temperature and ventilation of the house are interactive and affect each other. Ventilation is recommended at 0 to 4 weeks of age, usually with warmth preservation, other modes of compatibility, and hot weather areas requiring growth. The best time in the winter is at noon, and when the weather is good, you can increase the time and avoid losses. Focus on feeding details management. Drinking management during brooding cannot be ignored, and chicks begin to lose water one day after hatching. In order to prevent excessive water loss, timely guidance of chicks to drink water, improve the body's various functions. Such as long-distance transportation of chicks, should be added to the water in the amount of glucose, generally by 5% ratio, the water temperature should be close to the indoor temperature. Drinking water using a drinking fountain should be disinfected and cleaned daily. Because of the small gastrointestinal capacity of the chicks, it is necessary to pay attention to the nutritional ratio in the management of feeding, and to use hygienic and best-quality high-protein feed as much as possible. Do a good job in the group transfer. Usually the chickens can be reared at about 6 weeks of age. Attention should be paid to the temperature control of the chicken house during the transition, and there must be a process of adaptation. Don't switch quickly to avoid unnecessary stress. The amount of feeding should be reduced on the first day after the group is transferred, and it can be 65%-70% of the original amount. Only when the chickens are emotionally stable can the feeding amount be increased. This can effectively avoid the disequilibrium caused by the layer chickens and reduce the mortality rate. Epidemic prevention is a problem that must be paid attention to during the brooding period of laying hens. We must always pay attention to the characteristics of epidemics in the region and scientifically analyze and formulate immune procedures. Under normal circumstances, one-day-old laying hens can be injected with Malicious liquid oxygen vaccine, the dosage is 1.2 times, subcutaneous injection; 7 to 10 days old can be injected with Newcastle disease IV + transmission 120 dual vaccine, the dosage is 1.2 times, using eye drops Intranasal delivery can also be performed using renal transmission + glandular gastritis + Newcastle disease using subcutaneous injection; bursal vaccine should be used for intranasal prevention at 12 days and 30 days of age. The prevention and control of laying hens through laying a variety of effective vaccines is an effective guarantee. medical Angio Closure Pad,angio syringe,Angio Closure Pad Anesthesia Medical Co., Ltd. , https://www.medicaldiverse.com
