Five common factors affecting the ratio of eggs to eggs

Five common factors affecting the ratio of eggs to eggs

The ratio of chicken to egg refers to the amount of feed required for each kilogram of eggs produced by the chicken. When calculating the ratio of chicken to egg, the farmers should also consider other factors, because the factors affecting the ratio of chicken to egg are more dependent on the actual environment.

First, the impact of feeding methods on the ratio of feed to eggs

Judging from the current situation of laying hens in rural China, there are various ways of feeding, such as cage raising, online raising, ground raising, free-range, captive and so on. The production of large-scale laying hens is basically caged, and the ratio of eggs and eggs in cages is low, while in other ways, the ratio of eggs to eggs is significantly higher. This is mainly due to the increased exercise capacity of the laying hens and the corresponding increase in energy demand, so the consumption of materials is increased. As far as online raising is concerned, the daily consumption of each chicken is 10-15 grams more than that of caged ones. Other ways of feeding and feeding materials have to be increased, so it seems that cage laying hens (animal welfare is another matter) is of great practical significance for saving feed costs, reducing consumption, and increasing profits.

Second, the impact of environmental conditions on the ratio of feed to egg

1.House temperature

Considering several major economic indicators such as egg production, eggshell quality and feed efficiency, it is generally considered that 15℃~ 23℃ is the ideal range of room temperature control. However, considering the characteristics of outside temperature changes in different seasons, it is generally required that the house temperature in winter should not be lower than 15℃, and the summer temperature should not be higher than 30℃. Otherwise, it will have a significant adverse effect on the production performance of laying hens, which will increase the egg-to-egg ratio.

2.Lighting management

Light affects the egg production rate of the flock through regulation of feeding, drinking and endocrine. The change and control of the illumination time during the laying period should be carried out according to the lighting management requirements of the pre-production stage. From 19 weeks, the illumination time is gradually increased by 20-40 minutes/week, and the illumination is extended to 24 to 27 weeks old. The time is up to 16 hours to keep it constant.

3.relative humidity

Under suitable temperature conditions, the chicken has a large adaptability to the relative humidity in the house, and the relative humidity is between 45% and 70%, which has no obvious influence on the production performance. However, if the relative humidity in the adult house is too large, it is prone to problems, which may affect the ratio of the egg to the egg, and cause disease.

4.Ventilation

Under normal production conditions, the purpose of ventilation is to speed up the exchange of air inside and outside the house, thus ensuring an even distribution of airflow within the house. Strengthening ventilation in summer can alleviate the effect of heat stress, prevent heatstroke in the flock, and thus affect the egg production, so that the egg-to-bean ratio rises rapidly. In winter, in addition to regulating the temperature of the house, pay attention to the adjustment of energy feed.

Third, the impact of disease on the ratio of eggs to eggs

After many bird diseases occur, the target organ of the pathogen is the reproductive system, causing damage to the egg cells, so that some fake hens appear in the flock. After the disease is recovered, only the eggs are not eaten, such as the breeding period. This is the case for chickens with infectious bronchitis (IB), which seriously affects the overall egg production rate of the flock. The calculated egg ratio is surprisingly high. There are also some poultry diseases. Due to the long course of disease, the recovery of egg production during the recovery period is slow. At this time, the ratio of eggs to eggs is higher. There are also some chronic wasting poultry diseases. The pathogens are recessive infections or subclinical types. It is difficult to find the abnormality of the flock, but the consumption of the food is not reduced, the egg production is reduced, and the egg is maintained at a high level for a long time; the laying hen has different degrees of reduction in the occurrence of encephalomyelitis or egg drop syndrome. The egg causes the egg to rise

Fourth, the impact of stress on the ratio of eggs to eggs

Stress can cause the decline in production performance, egg quality and health status of laying hens, and the effect on the ratio of eggs to eggs is also obvious. Such as lack of water, lack of materials, sudden replacement of feed, excessive temperature, low temperature, house leaks, typhoons and other sudden changes and unexpected events, sudden changes in lighting time (blackout, lack of light or no lights at night); suddenly issued Abnormal sounds (horns, tools tipping over, thunder, etc.); strangers or other animals entering the house; changes in feeding management procedures; use of vaccines or drugs, etc., all of these stress factors will have varying degrees of impact Once the stress occurs, it will cause harm to the laying of eggs. The stress caused by these stresses will not decrease much. Therefore, the ratio of eggs to eggs is very high, and it must last for a while to come down.

Fifth, the impact of feed waste on the ratio of feed to eggs

For the time being, about 70% of the total cost of laying hens comes from feed. According to statistics, the waste that is wasted in the daily production of laying hens accounts for 3% to 5% of the consumption, for a 2,000-sized chicken. In other words, the value of wasted feed is equivalent to the wages of one breeder.

1.Improper storage of feed

The storage conditions are too bad, causing rats to steal food. According to research, a mouse can eat more than 9 kg of feed a year. As a result, the feed is reduced in total when it is not in the house, and the wrong data is obtained when calculating the ratio of the eggs.

2.Feeding method is not reasonable

It is not advisable to add too much at one time. If the amount of material exceeds 1/3 of the height of the trough, the waste of the birds will increase significantly when feeding, and the feeding action should be stable, accurate and fast, preventing the throwing feed during the feeding process and causing waste. 

3.Trough barrel waste

The design of the trough is unreasonable. The shallow bottom of the trough causes the feed to splash and lose when the birds are fed. The damage to the trough is not repaired in time, causing the feed to be scattered on the ground. If the chicken is not enough, the bottom of the barrel is not deep, and the flock is eating. The phenomenon of grazing occurs, causing the feed to pour off the ground. In addition, the materials are not cleaned up in time, causing spoilage and waste of feed, and such eggs are not easily perceived.
