What causes skipped laying in laying hens? Cause analysis and prevention and control methods
During laying hen production, it is common to see hens that lay one egg every two or three days; this is in fact the skipped-laying phenomenon in laying hens, and there are many causes. If it is not prevented and controlled in time, it will lead to a drop in laying hen output. This seriously affects economic returns. So how should it be prevented and controlled? Let's take a look together with the editor.
I. Main causes
For those who raise chickens, it is generally understood that laying hens usually reach their peak at 180-220 days, and when this peak is passed, if the laying rate still cannot rise, then it shows that the possibility of the flock's laying rate increasing is not great. When analyzing the causes of a low laying rate in the flock, the skipped-laying phenomenon may appear; skipped-laying hens have fewer mature follicles and relatively few fallopian tubes, which is caused by damage during the development of the fallopian tubes leading to incomplete development.
II. Triggering causes
1. Reproductive-type infectious bronchitis
When the flock shows symptoms of tracheal blockage at around 70-80 days, then even if the infectious bronchitis vaccine is given in time, the flock's reproductive system may also be damaged, affecting the normal development of the fallopian tubes. However, it does not mean that the fallopian tubes of all chickens develop abnormally; rather, some show incomplete development, so these chickens will lay one egg every 2-3 days.
2. Poisoning
During the development of the flock, if severely moldy feed is collected or toxic and harmful substances are ingested, then the reproductive system will also be damaged, causing incomplete development of the fallopian tubes and ovaries.
3. Infection with other viruses
During the development of the flock's reproductive system, if the flock is infected with viral diseases, such as influenza, and has a prolonged fever, it will also cause incomplete development of the fallopian tubes and ovaries.
4. Insufficient nutrient supply
If during the development of the reproductive system, the flock is infected with viral diseases, such as influenza, and has a prolonged fever, it will also cause incomplete development of the fallopian tubes and ovaries.
III. Prevention and control methods
If the fallopian tube damage was caused in the earlier stage, then there is no way to make up for it in the later stage, so according to the size of comb development, select the skipped-laying hens by output, separately give them traditional Chinese medicine for inducing labor and increasing egg production, so that they produce healthy eggs in a short time, and then cull them in time. In addition, in the earlier stage, corresponding preventive measures should also be taken against the above triggering methods to avoid the skipped-laying phenomenon as much as possible.
