Improving the egg production rate of laying hens requires certain measures. Here are some good measures to share with you:
Pay attention to selecting qualified high-yielding eggs. For chickens, the qualification is based on the unity of body weight, leg length and uniformity on the basis of survival. The specific manifestations are in the following aspects:
Yue wants a fat chicken. The age-old weight of laying hens determines the egg-laying performance throughout their lives. The heavier the egg-age weight, the higher the survival rate during the breeding and laying periods, the earlier they start laying, and the longer the egg production peak is maintained.
Two months to reach double standard. That is to say, the growth of chickens must have double standards of weight and size. The weight and body shape during the breeding period must meet the standards required for this breed. If the body weight is higher or lower than the starting standard, it is generally difficult to reach the peak egg production. Body shape is usually measured by shin length, which is measured from the sole of the foot upward to the top of the hock joint. For example, the shin length of a Dika laying hen should be 3. If the shin length is not reached at the age of one week, the brooding material may not be changed temporarily. .
The uniformity should be good. Good uniformity means that the four uniformities of body weight, body shape, body maturity and sexual maturity are all up to standard. The greater the difference between individuals, the worse the uniformity, resulting in unstable egg production rate and low egg production performance.
, Prenatal maturation and sexual maturity should be synchronized
Sexual maturity means blushing and opening the crotch. Whether the body is mature: First, check the replacement of the main wing feathers. It is normal for eggs to appear if ~3 pairs of main wing feathers are not replaced. Second, check whether the weight is up to standard. Timely changing of feed means changing the feed when the weight reaches the standard instead of changing the breeding feed as soon as the dog reaches the age of one week. Small body weight, less replacement of main wing feathers, substandard shin length, and low initial egg weight are all signs that they have not reached physical maturity. Only when sexual maturity and physical maturity reach the standard at the same time can the egg production peak be reached quickly.
Pay attention to the chicken feed
Broiler chicken feed can be used to feed the fat chickens before three weeks of age. Later, brooding feed with higher nutritional level should be used until the shin length reaches the standard before changing to the finishing feed. After feeding egg-laying feed, the egg production rate will increase within the specified time and the egg weight will be small. If the chicken flock and feeding management are normal, the feed quality should be checked. Generally, if the feed energy is insufficient, the egg production rate will be low, and if the protein is insufficient, the egg weight will be small.
, control reasonable light
The sexual organs of laying hens begin to develop after they are 10 days old. At this time, the light should be controlled, especially the light time after the age of 10 days must meet the standard. It cannot be shortened or lengthened, and the light intensity cannot be Do not weaken or lengthen, otherwise sexual maturity will be delayed or advanced.
, Find low-producing chickens and false-producing chickens
Check the shin length of the chickens, select the chickens whose combs are not red or the crotch is not open among the chickens that are laying, and select the chickens in the middle stage of laying. Fat chickens with bright yellow beaks and legs are placed in cages for observation and those that have partially molted are picked out.
, prevent diseases and take measures to regulate and increase eggs
Some chickens suddenly drop in egg production or develop abnormal egg shapes without changes in feed and environment. The cause of the disease must be considered and preventive measures should be taken daily. To control the work, the fermented traditional Chinese medicine egg and poultry vitality can be added to the mix, which has the effect of conditioning eggs and increasing egg production rate.
