Modern broilers grow much faster in the early stages than broilers in the past. The weight of a week is about 3 to 4 times the weight of the newborn. Correctly doing the brooding work a few days ago makes chicks have a good start, which is extremely important for broiler production. The key factors affecting the final production performance of broiler chickens include: chicken house hardware facilities, environmental conditions and management in chicken houses. This article will discuss the early management of broilers from these three aspects for your reference.
Ensuring comfortable environmental conditions In the hatchery, chicks live in high humidity environments. In order to prevent the chicks from dehydrating in the house, the humidity in the house should be carefully adjusted in the first week. At about 1 week of age chicks can regulate their own body temperature. Therefore, before the chick arrives, the chicken house should be pre-heated and the temperature and humidity should be kept comfortable.
During the first seven days, the temperature and relative humidity in the room should be checked frequently, at least three times a day, and thereafter at least once a day. In order to more accurately detect the environment in which the chicks are located, the temperature probe should be as close to the chick as possible, in addition to using a conventional thermometer to proofread the electronic probe of the automatic control system.
In the first three days, high humidity and temperature should be maintained so that the chicks have an adaptation process to the external environment. The relative humidity in the house can be maintained at about 70%. Low humidity (less than 50% humidity during brooding) will cause dehydration, negatively affecting the performance of the birds.
The air quality in the first week is also very important. Through reasonable ventilation, the temperature and humidity are kept at an appropriate level, and harmful gases are discharged outside the house. From the outset, a minimum ventilation program to provide fresh air and remove harmful gases should be established. In addition, the use of a circulating fan in the house also helps improve air quality.
Pay close attention to the behavior of the chicks. The behavior of the chicks is their best feature for temperature perception. Since temperature and humidity determine the sensible temperature of a chick, the relationship between temperature and humidity is very important.
House layout In order to seize all growth opportunities, chicks should establish a healthy appetite with good eating and drinking behavior as soon as possible. In the final analysis, we should try to make 1-day-old chicks freely exposed to feed and water. In order to reduce the stress on the chicks and ensure good early growth, the chicken house layout should be done before entering the chicken, and the distance that the chicken must walk must be minimized in order to feed for drinking. Before preparing chickens, follow the following guidelines:
Cover 30% of the brooding area with paper.
Spread the feed evenly over the paper, about 50 grams to 70 grams per bird (equivalent to three days of feeding).
Put the chicks on the feed instead of asking the chicks to find their own feed.
Feed grain size should be appropriate, such as sifted crushing material.
Less than optimal 7-day-old weight is usually due to the fact that chicks cannot feed enough feed and water. If the temperature of the brooding house is too high, the appetite of the chicks will be suppressed, feed intake will be reduced, and the growth rate will be suppressed. Birds that do not reach the standard body weight on the 7th day will also have poorer uniformity. Therefore, in order for chicks to have a good start, it is necessary not only to improve the environmental condition of the chicken house, but also to make it easier for the chicks to obtain water and feed. A good start will promote the growth of chicks, improve the uniformity of the flock, feed conversion efficiency and survival rate.
The actual effect of management and inspection management It is very important to check the diet of the chicks. By checking the fullness of the crop, chicks can be assessed for the first 48 hours of feeding and drinking. Ideally, if the chicks feed normally, then the sac should be filled with feed and water, round, and the content is like a soft ball. If the crop is flat or the contents are hard and the feed pellets may be touched through the walls of the sacs, then the chicks do not have enough feed or drink enough water.
If after 8 hours of eating, 80% of chicks are full of crops; after 24 hours, 95% of chicks are full of crops, then it means that all the chicks get enough feed and water. If the hernia sac fullness is lower than the above goal, then it is necessary to increase the paper area, adjust the temperature and humidity inside the house, or provide additional feed. If there is water shortage after 24 hours, then the water pressure should be adjusted so that the water droplets can be hung on each nipple within 24 hours, or there can be enough water in the water tray to make each chick Drink enough water.
Measuring 7-day old body weight is also an effective method to assess chicks' dietary status. At the age of 7 days, samples were weighed and the average body weight and evenness were calculated. These two indicators will show the effectiveness of early management.
Based on the characteristics of the chicken farm and the company management system, a record sheet detailing the fullness, average weight and evenness of the crop was designed to evaluate the feeding and management of the first seven days. This record sheet is an effective tool for assessing and improving the management of broiler chickens. It should be included in the quality control system of broiler farms. It should be carefully filled out and kept.
Converting to an Automatic Feeding System When you have eaten a day-old diet and started running an automatic feeding system, chicks face the second challenge of affecting growth and feed shortages. The following methods will help solve this problem:
Add additional feed to the paper so chicks have enough time to find the feeder.
Move the sprinkled paper near the automatic feeding system.
Fill the feeder with feed.
Again, the fullness of the crop was evaluated, the samples were weighed, and the average body weight and evenness were calculated to assess the feeder turnover.
In short, in order to achieve the growth potential of broilers, a good start must be made for the chicks; in order for the appetite to develop as early as possible, it is important to manage the environment of the broiler house to ensure that the chicks feed enough feed and drink enough. water.
