Factors Affecting the Quantity of Quail Egg Production

Date:2021-1-30      Author:Egg washing machine

Quail eggs are nutritious and delicious and are a favorite food for many people. There are many factors that affect the production of quail eggs in the process of raising quail eggs. This article shares what factors affect the production of quail eggs.

Quail Egg Production

1. The influence of genetic factors on egg production rate

Genetic factors are one of the important factors that determine the level of quail egg production. Different quail species have a big gap in the egg production rate during the same period. The egg production rate of meat-type quail (such as Defac) is only 70% during the peak egg production period, while the egg production rate of egg quail varieties (such as North Korea Longcheng and Nannong Huangyu) can reach 85% during the same period. White feather quail is as high as 95% to 98%. Therefore, it is necessary to raise different quail species according to different feeding purposes.

2. The effect of age on egg production rate

Egg quails generally begin to lay eggs at the age of 35-40 days, and the egg production rate can reach 50% at the age of 45 days. The egg production peak can be reached at the age of 65-70 days, and the egg production is very persistent. Before the age of 12 months, the egg production The rate can always remain above 80%.

After 12 months of age, although the egg-laying rate of quail can be maintained at about 80%, the dead-battering rate, and the feed-to-egg ratio
Increasingly, the hardness of eggshells is poor, and the breakage rate of quail eggs is high, which seriously affects the economic
Economic benefits. Therefore, the general breeding period of egg quail does not exceed 12 months.

3. The impact of the disease on egg production

Many diseases such as Newcastle disease, quail white scour, colibacillosis, fowl cholera, etc. will have varying degrees of impact on the performance of quail egg production. Among them, white scour and colibacillosis have the greatest impact on egg production.

After a quail is infected with white dysentery, the disease can last up to several months. In addition to vertical transmission, horizontal transmission can also occur before exhaustion and death, which can cause disease in the entire cage or a certain group of groups and reduce the egg production rate by more than 20%, And the quality of eggshells is seriously reduced.

At the same time pay attention to the sanitation of feed, drinking water, and environment. Only by establishing a strict disease prevention and elimination system can the high and stable yield of quail be guaranteed.

4. The effect of feed and drinking water on egg production rate

Quail egg rearing

(1) . The influence of feed on egg production rate

A reasonable feed is one of the necessary conditions for high and stable quail production. For quails, the egg production rate is high, and the nutritional value of the eggs is high, which inevitably requires a high nutritional level of the feed. The energy content per kilogram of feed should reach 2800 kcal, and the crude protein should be 20% 6-22%. It is necessary not only to adopt a good feed formula but also to pay special attention to the quality of various raw materials. Quail feed with different ingredients in the same feed formula can make the difference in quail egg production rate of 10%-40%.

It is worth noting that the higher the protein content in the feed, the better. When the protein content in the feed reaches 28%, after 1 week of feeding, the egg quails will have protein poisoning, causing tissue edema, and resulting in production suspension.

In addition, the uneven mixing of the feed often causes salt or trace element poisoning, resulting in a drop in egg production.

(2) . The influence of drinking water on egg production rate

Infeed, the dissolution, and absorption of many nutrients are inseparable from water. Quail’s water intake is generally 2-3 times the feed intake, and it needs 50-75 grams per day. The egg quail is without water for 24 hours (heatstroke in summer), the egg production rate can be reduced by 40%, and the normal water supply can be restored to normal in two weeks. If the water is stopped for 40 hours, the quail will stop production, and even die of thirst, and the egg production rate will be restored within one month of normal water supply.

Quail drinking water must be clean, hygienic, and pollution-free, and adequate drinking water must be maintained for 24 hours. Quail houses that use automatic drinking fountains must always check whether the drinking fountains are blocked.

5. The impact of the environment on egg production rate

(1) .  light

During the laying period of egg quail, the light time should be controlled at natural light + artificial light = 16 hours per day. Egg-laying quails like soft light, 40-watt incandescent lamp is suitable. Too strong light or too strong natural light will cause severe hair loss and premature aging of quail and reduce egg weight. Suddenly reducing the light time to 8 hours a day, the quail will also shed hair, and the egg production rate will be reduced by more than 50%. 24 hours of light does not have any meaning to increase the egg production rate but will increase the consumption of word materials.

(2). Temperature

Compared with chickens, quails are smaller in size but have a larger heat dissipation area on the body surface (the weight of 10 adult quails is equivalent to one chicken, but their total skin area is one time larger than that of chickens), which determines the high-temperature resistance and fear of quails. The cold habit. When the shelf temperature is lower than 20^C, the egg production rate will drop by 10%, and when it is lower than 10^C, it will drop by 60%, or even stop production, and the disease resistance will be significantly reduced and the mortality rate will increase. In a short period of time (3-5 hours), the room temperature reaches 36C, which has little effect on egg production. The most suitable temperature during the laying period is 25-30C. It is best to use a temperature-controlled stepless variable-speed ventilation device for quail house skylight.

(3). Density

In a stepped quail cage, it is advisable to raise 60-70 quail per square meter. If the density is too large, it will inevitably affect the feeding and movement space of quail, which will cause a decrease in egg production.

(4) . Ventilation

Ventilation should be carried out under the premise of ensuring the house temperature. But it can’t just for heat preservation without ventilation. Many breeders keep the house temperature in winter, and all windows are closed, causing serious excess of carbon dioxide and ammonia in the quail house, which not only reduces the egg production rate but also easily causes epidemics. In the case of low room temperature, a stove can be started to increase the room temperature, and then ventilation. It is best to choose sunny and windless noon for ventilation.

(5) . Humidity

Egg-laying quails are highly adaptable to humidity, and the relative humidity of 50%-70% is suitable for the development of egg production rate.

(6) . Quail house hygiene

frequent cleaning of manure, frequent cleaning of water utensils, and frequent disinfection are all conducive to the development of egg production rate.

(7) . Noise

Quail has a much greater tolerance for noise than chickens. Generally, the noise of motor vehicles will not cause quails to startle their groups, but especially loud and crisp sounds (such as firecrackers) can easily cause quails to startle their groups or even hit them. Cage and die, resulting in a drop in egg production.

(8) . Wind size

The egg production rate of quail has a great relationship with the strength of the wind. Sudden 5-6 winds can reduce the egg production rate by 10%-20%.

(9). weather factors

Sudden changes in the weather and sudden cooling can reduce the egg production rate of quail by more than 10%. Long-term rainy weather can cause insufficient light, large temperature differences, and reduce disease resistance of quail. It can also cause E. coli outbreaks, thereby affecting egg production.

(10) . Rodent damage

Rats are natural enemies in quail breeding. They not only steal feed and spread diseases, but also steal quail eggs and kill quails. An adult mouse can kill more than 10 quails overnight and drag away a dozen or even hundreds of quail eggs. The damage caused by one mouse to the quail can reach more than 100 yuan a year. At the same time as killing rodents, pay attention to flies.

Raising quail is not easy. There are many things that need to be paid attention to at all times. Only by raising quail carefully can the production of quail eggs be guaranteed.
