Good breeding management of breeding chickens creates high-quality breeding eggs. The transportation of breeding eggs on the farm needs to be carefully operated and follow operating procedures, paying attention to key parameters such as storage temperature and stress.
Even a good breeder farm manager needs to know what kind of eggs will be produced in his hen house. High-quality breeding eggs come from the breeding young hens they receive. It is necessary to discuss the CV of the young hen with the breeding manager. The weight and average weight of 1-day-old young hens should reach the expected level, and the weight of each stage, including the average weight and the expected weight at the time of transfer, should also reach the expected level.
When the chicks arrive at the breeding farm, they should be accompanied by a flock immunization report, including possible reactions in the flock and laboratory-tested antibody levels. You can also consult a veterinarian to consult the next immunization time of the chicks and develop a scientific immunization program. This process will continue until the breeding chickens are eliminated (61-64 weeks of age). For commercial layer breeds, this time will last to 70 to 72 weeks of age.
1 Prepare carefully
Homogeneous breeding eggs produced by highly organized chicken flocks are the most important part of the entire breeding egg production industry. Whether it is a regional breeding goal or for rearing, it is very important to control the weight of the out-of-shell chicks within 50 g. Light is also a key factor affecting the weight of chicks. The lighting program should be preset according to the current needs. People first need to understand the current lighting program from the chicken farm operator of the breeder production farm and make some necessary adjustments. Regardless of whether the flock is transferred from a closed brooding house to a closed laying house, or to an open naturally ventilated house with or without curtains, the rooster must be raised separately from the hen and before the mother Chickens are transferred to the laying hen house for 2 to 3 days. According to different breeds, the weight and development of males should meet breed standards.
Feed should be delivered to the chicken house 2 to 3 days before the rooster arrives. The water supply system needs to be adjusted to the correct height and maintain the corresponding pressure to ensure adequate water supply. This can be fine-tuned after the chickens arrive, but a good breeder will make these arrangements in advance. The preparation checklist can tell chicken farmers that these water pipes have been shaken and flushed to avoid biofilm in the drinking water system. If the drinking water has a relatively high hardness, it may be beneficial to use a water softener, which will greatly reduce the accumulation of scale in the drinking water pipeline. Ideally, the pH of drinking water should be 6.5, but a pH between 5 and 7 is also acceptable.
When the chickens have started laying eggs, it is too late to repair the problems in the egg storage room. Full preparation should not overlook any details. When overhauling the egg storage room, check the special trolleys for the incubator to ensure that they can move smoothly, make sure that the required repairs have been completed correctly, and verify that the cooling equipment and humidifier are operating normally. This calibration is often overlooked. The calibration of thermometers and hygrometers should be performed by technicians within one day after the cleaning is completed, not the day before the hens are shipped.
2 Details create profit
Thorough cleaning of the chicken house will affect the performance of the next batch of chickens. This also means that the farmer must be satisfied with the test results of the samples collected from the entire laying house and its facilities. If you are not satisfied, the suspicious area must be re-evaluated, cleaned and disinfected again, and then re-tested to ensure nothing is lost. Please remember that in the poultry production system, any mistake will cause economic loss, and no mistake or contempt is allowed. Everything must be correct once and every time. This must be part of the cultivation of all poultry practitioners, regardless of their status.
3 Equipment and items
No matter what type of nesting box is used, it is extremely important to place it properly and be easy to use by the laying hens. It is essential that the nesting box is properly designed, well ventilated, and placed properly in the house. Such a nest can attract hens to lay eggs here. Otherwise, many ground eggs will be produced and many high-quality chicks will be lost. The area where the nest is not bright is also the key.
The treated/fumigated dry white pine shavings are compacted and transported. It is best to use a plastic bag that is completely covered and sealed, or use a certain synthetic resin bag, assuming they have been treated in the same way. A pile of the above-mentioned litter is also needed for adding or replacing when needed. Perhaps some local organic material can also be used. The litter of the laying box must be kept clean and not contaminated by feces, and the chicken feces should also be removed when collecting eggs. Further removal or replacement of litter should be done after the last egg collection in the afternoon.
There are currently many ways to combine chicken coops and available equipment, from slatted floors to various types of litter and manual or automatic egg collection systems, and automatic or manual egg collection. People often have difficulty choosing these devices, and many times make decisions based on price, and in some cases this factor even determines the final choice. This is a simple economic question, and most of the available equipment systems can operate normally. The most fundamental factor is the management level and professional knowledge possessed by the breeder.
4 Egg production stimulation
The lighting program should be set up to encourage most hens to lay eggs in the morning (until 12:00 noon), so that the eggs can be easily collected, fumigated and disinfected and transported to a storage room with a room temperature of 16 ℃ ~ 18 ℃ and a relative humidity of 75%. In the egg room, the last egg collection should be done in the afternoon. This ensures that most of the breeding eggs can be transferred to the egg storage room before noon, which helps prevent the hen from sitting on other eggs before laying, reduces broken eggs and prevents embryos from starting to develop when the egg temperature exceeds 24 ℃. Relative humidity is also very important, because in warm seasons or low relative humidity in summer, egg evaporation increases and egg weight decreases, resulting in a decrease in the weight of chicks. Relative humidity also affects the size of the egg chamber. If egg collection is not carried out regularly, the control of relative humidity is even more important because the temperature of the eggs will rise.
Scientific data shows that eggs produced earlier in the day have thicker shells and are not easily broken. The stratum corneum is a coating covering the surface of the egg shell, which helps prevent the inside of the egg from being contaminated by bacteria; once the inside of the egg is contaminated, it will cause many problems inside the egg. Many years ago, the British Egg Marketing Committee emphasized the importance of not washing the eggs or even wiping off the stains on the eggshell surface. It believed that this would destroy the keratinous membrane on the surface of the eggshell, allowing bacteria to enter the inside of the egg, which would shorten the shelf life of the egg. . For breeding eggs, washing will reduce the proportion of hatched eggs and reduce the number of first-class chicks.
5 egg storage
In many cases, the breeding eggs will be collected on the plastic egg cart in the incubator. This facilitates rapid cooling when transported from the breeding egg-laying house through the fumigation room to the cool room and placed in the cool storage room for collection. Breeding eggs can be graded at the production site, and the room temperature is maintained at 16 ℃ ~ 18 ℃. If you don't use the plastic tray of the incubator for collection, you can use the second only ordinary plastic egg tray that can hold 30 eggs. Eggs in different laying houses can use different colored trays to distinguish them.
It should be noted that the embryo in the egg will begin to develop after the temperature exceeds 24 ℃. Therefore, the alarm system connected to the egg storage room should set the maximum temperature at 21 ℃ and the minimum temperature at 16 ℃ ~ 18 ℃ is very important. Make sure that the room temperature has been set, and check and record the temperature daily. The refrigeration capacity of the transport vehicle is also very important. It must be checked when transporting to the hatchery. The temperature of the carriage should be easily maintained at 16 ℃ ~ 18 ℃, while the relative humidity should be maintained at 70% ~ 75%.
It is not recommended to use paper egg boxes/trays to collect eggs, because this type of fiber material will absorb the heat of the eggs and it will take longer to cool them down. In the hot season, this can cause problems even more. Because fiber trays have many pores, they will become a haven for harmful microorganisms/bacteria/fungi and attract parasites.
This paper egg box / egg tray facilitates the transportation and storage of the day’s breeding eggs at the correct temperature and humidity, until they are taken out of the hatchery.
Breeding eggs can be graded at the production site, packed in plastic pallets, and loaded on a cart dedicated to the incubator. In the hatchery, the breeding eggs need to be fumigated again before being put into the incubator. After that, it must be placed for a certain period of time before being sent to the Single Stage (SS) or MultiStage (MS) incubator. Another way is to grade the eggs in the hatchery. According to the time that can be hatched, it is best to let the eggs stand up, which can make them stable before being put into the incubator for incubation. This method can improve the hatching rate of the eggs and the quality of the chicks.
6 Daily recording is very important
Feed consumption per rooster/hen per day;
House temperature: minimum / maximum;
Laying box temperature, laying box litter surface/air temperature;
Laying rate: the rate of laying hens in the house and the daily laying rate of hens;
Male/female ratio, record deaths;
The number of deaths per day, the number of deaths of each male/hen;
Timer setting;
Water Consumption;
Relative humidity of the chicken house, the number of measurements per day;
Chicken flock health indicators;
Observe the water content/quality/color/odor of chicken manure.
