Standardized and scientific feeding methods to improve the laying rate of laying ducks

laying ducks

The living environment of ducks changes day and night alternately. Affected by this, some habits of ducks also have the law of day and night changes corresponding to it. If we can conform to this change rule in production, carry out standardized and scientific feeding, we can raise and manage duck flock well, reduce feeding cost, effectively improve laying rate of laying duck, and thus improve feeding benefit.

1. Diurnal variation of duck feeding

Under natural light, ducks had three feeding peaks in a day and night, in the morning, noon and evening respectively. Therefore, the following measures should be taken in feeding management: 1. Strengthen early feeding. Ducks have a particularly strong appetite at dawn, when they are fed and fed well to make laying ducks lay more eggs. 2. Grazing time. Grazing should be carried out at the peak of feeding for ducks in the morning, middle and evening. At other times, let ducks rest or drive them into the water, combining work and rest. If drinking water, dosing or mixed feeding is required, it is best to arrange it at the peak of duck feeding.

2. Diurnal variation of duck egg laying

It is reported that laying ducks lay eggs mainly after midnight to dawn, usually not during the day. In order to improve the laying rate, the following measures should be taken: 1. Turn off the lights at 10 p.m. on time and stop the lighting to ensure that the laying ducks lay eggs in a quiet environment from 1 to 4 p.m. the next day. 2. If ducks are found to lay eggs generally later than 5 o 'clock, and the egg head is small, it means that the concentrate in the diet is insufficient, and concentrate should be added in time according to the standard. 3. If ducks lay eggs during the day, it is mostly due to poor environment such as single feed, insufficient nutrition, early grazing in the morning or high temperature and humidity in duck houses. The breeding and management conditions should be improved and the grazing time of ducks in the morning (8:00) should be temporarily postponed.

3. Diurnal variation of duck mating

Breeder duck mating generally choose morning or evening, in the vast water surface. Therefore, we should make full use of the mating peak in the morning or evening to drive them to deeper waters to improve the fertilization rate of breeding ducks.

4. Diurnal variation law of Youshi disease

Youshi disease is named after ducks who get sick at Youshi (17~19 o 'clock) every day. When the disease occurs, ducks are violently agitated and quickly gathered, resulting in some weak ducks being trampled to death, and the mortality rate is often about 20%. This disease is caused by transportation stress, so we should try our best to reduce all kinds of stress before and after long-distance transportation of ducks. In order to prevent Youshi disease, anti-stress drugs should be added to the diet 1~2 hours before Youshi every day within a few days after egg duck transportation.

5. Diurnal variation of immune response

The sensitivity of poultry to immune agents (vaccines, vaccines, etc.) varies periodically from day to night, with poor sensitivity and slow immune response during the day; adrenaline secretion is the most sensitive and immune response is the most sensitive at night near dawn. Therefore, immunization of poultry (including ducks, geese and chickens) is effective in the early hours of the morning. There are two advantages: 1. Poultry stops at night, easy to catch, and stress response is small. 2. Vaccination at dawn every day allows them to develop immunity faster and better.
