In spring, the temperature rises, germs begin to multiply, and the temperature difference between day and night is large. Moreover, after a long winter, the chickens are of weak constitution, so spring is the season of high incidence of chicken diseases. At this time, the physiological function of the chicken is also growing, and the egg production is rapidly increasing. Therefore, spring is also the peak season for egg production and reproduction of chickens. There are two central tasks in the spring laying hen rearing management: one is to ensure the health of the flock, and the other is to ensure a higher egg production. The spring feeding management techniques are summarized as follows:
First, feed nutrition technology points in early spring, when the warmth is still cold, the feed should be properly increased the proportion of corn and other energy feeds to enhance the ability of the body to resist cold. The suitable energy level is 2.75-2.85 megakascal per kilogram, the energy is too high, the feed intake of the chicken is low, and the protein intake is insufficient. This not only results in energy waste, but also affects the chicken's intake of protein.
In the middle of the spring, when the temperature has risen, the egg production rate of chickens has also increased. It is necessary to appropriately increase the nutritional level of the diet and increase the egg production rate of the chickens. The crude protein content must not be lower than 16.5%. For every 10% increase in the egg production rate, the crude protein in the diet should be increased by about 10%. When the egg production rate rises, high protein feed should be fed one week in advance. If the eggs produced at this time are used for breeding eggs, attention should be paid to the complete feed nutrition, and vitamin A, vitamin C, and vitamin B should be properly added.
In the late spring, it is the most suitable period for chicken production. Temperature and humidity are the most favorable conditions for laying eggs. The chickens in the pre-production period and the early stage of egg production need large amounts of nutrients to meet their egg production and weight gain. According to the determination, the average daily weight gain of chickens during this period is still about 4 grams, and the chickens in this stage are not the most The average daily feed intake is only about 100 grams, so it is necessary to properly increase the nutritional level of the diet during this time, otherwise it is difficult to meet the nutritional needs of chickens. At this time the dietary energy should reach 2.65 to 2.80 Mcal/kg, crude protein 17% to 18%. The reason for raising the protein level is that hens consume more protein during the laying period and their consumption is related to the chicken's egg production rate. Therefore, the protein raw material in the feed should be increased according to the increase in chicken egg production rate. The method is Add appropriate quality fishmeal, soybean meal, etc. to the diet, and try to add as little as possible when costs allow.
Second, the daily management of technical points In the early spring, we must pay attention to the insulation of the chicken house, try to make the temperature of the laying hen house maintained at 10 °C or more; at the same time also take into account the ventilation. Open the doors and windows at high temperatures at noon every day to discharge harmful gases. The cold protection facilities should be gradually removed according to the situation, but care should be taken to avoid catching cold in the flock. The temperature difference between bred and layer-laying hens should be controlled within 6°C to avoid loss of production due to temperature instability. In addition, pay attention to the illumination time. The laying hens should turn on the light at 5:30 or 6:00 every morning and turn off the light at 9:00 or 9:00 pm to make the light time stable at 16 hours. If you use red light better. The light intensity is preferably 10 lux, that is, a 25 watt incandescent lamp is installed every 3 meters in the front, rear, left and right, and the lamp is 2.1 meters high, and an umbrella is installed. The bulb should be wiped once a week to maintain sufficient illumination. The adjustable transformer is set to make the light gradually darker and darker when the switch is on and off, so as to reduce the stress on the flock. At the same time install the light time controller to make management more convenient.
In the middle of the spring, there are few diseases and we must seize the opportunity to strengthen the purification of the disease. In order to maintain a high egg production rate, the management systems must be relatively stable to prevent stress and reduce the chicken production rate. Stress is the source of all diseases. In this period, the temperature is erratic, hot and cold, and the stress of starting production itself makes the chickens in a sub-healthy state for a long time, thus inducing various diseases. As far as possible, some measures should be taken to reduce the impact of stress on the chickens. The feeding and management procedures should be standardized. The timing of feeding should be sufficient. The water supply should be sufficient, and the operating procedures should not be changed at will, such as feeding, quail eggs, and cleaning. , can lead to decreased egg production, and even the incidence.
In the late spring, it is the season for the proliferation of microorganisms. Insects, such as mosquitoes and flies, also begin to breed. The climate characteristics of windy and rainy are conducive to the spread of diseases. To do a good job in environmental sanitation and strengthen prevention of epidemics should be the focus of day-to-day management. Thoroughly clean inside and outside the chicken house and inside and outside the chicken farm to reduce the threat of disease. In addition, diseased, weak, disabled and other non-laying hens were selected from the flock to eliminate disease prevention work, and excrement, diligent disinfection, and the number of quail eggs were increased. The conditional chicken farms should carry out antibody monitoring for Newcastle disease, infectious bronchitis, and other diseases, and if abnormalities are detected, they can be immediately immunized and can also be administered preventively.
