For laying hens, pecking fetish, although the incidence is not high, generally less than 0.5, but in the whole laying period will exist, the loss of production is relatively large.
Specific reason analysis:
Pecking addiction is often the result of many factors, rather than a single factor.
① Chick stage, predisposing factors may be:
The light intensity is too strong, the light time is too long;
High temperature and poor ventilation;
Improper beak-cutting; hypoplasia of feathers;
Feeding density is too large; lack of nutrients: such as water supply, lack of sulfur-containing amino acids, salt, crude fiber;
Long-term suffering from diarrhea and respiratory diseases can easily lead to malnutrition.
② The reasons for the occurrence before and after the peak period are:
Too much body fat in the back-up hen;
premature light stimulation;
Dietary protein/amino acid levels are too high, causing large eggs.
Lighter body weight is the main predisposing factor for multiple pecking in flocks during the peak period. Lighter chickens are more neurotic, low in intake and nutrient deficiencies, and tend to peck at other chickens.
In order to preterm large eggs, feed light hens with coarse and high protein, which will aggravate prolapse of the rectum. If further combined with light, it often leads to the phenomenon of producing more double yolk eggs.
Solution:
The most effective measures to avoid pecking anus: keep the light intensity and time appropriate;
② Improve the uniformity of the breeding flock;
③ Preventing premature feeding of high protein feed;
④ Provide a reasonable feeding environment and sufficient drinking water.
