What are the physiological characteristics of laying ducks?

1) Egg-laying ducks are bold and completely different from the young duck period, after laying eggs, they are bold, not only not afraid of people, but like to approach people.

2) Egg-laying ducks foraging diligent regardless of captivity and grazing, egg-laying ducks (especially high-yielding ducks) are the most diligent in foraging, wake up early in the morning and call early, look for food everywhere after leaving the house, forage everywhere when grazing, the first to respond when feeding, and when grazing or entering the house in the afternoon, although they are full, they always walk at the end, and they are reluctant to leave the pastoral area.

3) laying ducks have a docile temperament and like to leave the group after the ducks, the temperament becomes docile, after entering the duck house, they lie down alone, sleep quietly, do not run around, graze out, and like to move alone.

4) Egg-laying ducks have strong metabolism and high requirements for feed Due to the need for continuous egg production, the nutrients consumed are particularly large. If the nutrients in the feed are not complete, or if there are several elements lacking, the egg production will decrease, such as the number of eggs will decrease, the eggs will become smaller, the eggshell will become thinner, or the contents of the eggs will become thinner and lighter, or the duck body will be emaciated until it is discontinued. Therefore, laying ducks require higher quality feed, especially like to eat animal fresh feed, and the roughage that is often eaten during the young duck period is no longer fond of eating.

5) laying ducks require a quiet environment Life is regular Under normal circumstances, ducks lay eggs in the middle of the night at 1 2 o'clock, at this time in the dead of night, without any noise, the best in line with the special requirements of birds to breed offspring. If the light is suddenly stopped at this time, it will cause a riot and a crowd will appear. In addition to laying eggs, the duck house should also be kept relatively quiet, and strangers should not be allowed to enter and leave the duck house, so as to avoid all kinds of birds, beasts and animals in and out of the house.

In the management system, when to put ducks, when to feed, when to rest, to establish a stable law of life, such as changing the number of feeding meals, greatly adjusting the feed variety, will cause duck physiological disorders, resulting in the consequences of production shutdown and reduction.

The stage from the beginning of laying eggs to the culling of female ducks is called laying ducks. Generally, the use period of egg type hemp duck is about 350 days (150 500 days old), called the first egg laying year, and there are also after moulting and resting, and then reuse the second and third years, but its production performance declines year by year, and it is not suitable to be retained.

1) Egg-laying ducks are bold.

Completely different from the young duck, after the female duck lays eggs, she is bold, not only not afraid of people, but likes to approach people.

2) Laying ducks have a docile temperament and like to be outlied.

After the start of production, the duck temperament has become docile, after entering the duck house, they lie down alone, sleep quietly, do not run around, graze out, like to move alone.

3) Egg-laying ducks forage frequently.

Regardless of captivity and grazing, laying ducks, especially high-yielding ducks, are the most diligent in foraging, waking up early in the morning and calling early, looking for food after leaving the house, foraging everywhere when grazing, the first to respond when feeding, and when grazing or entering the house in the afternoon, although they are full, they always walk last, and they are reluctant to leave the pastoral area.

4) Laying ducks have strong metabolism and high requirements for feed.

Due to the need for continuous egg production, the consumption of nutrients is particularly large, such as laying 1 egg per day, the egg weight is calculated according to 65 grams, then you need crude protein grams (calculated according to the crude protein accounted for the whole egg), crude fat grams (calculated according to the crude fat content of the whole egg), in addition to inorganic salts and various vitamins. The nutrients in the feed are not complete, or there is a lack of certain elements, the egg production decreases, the number of eggs decreases, the eggs become smaller, the shells become thinner, or the contents of the eggs become thinner and lighter, or the duck body is emaciated until it is discontinued. Laying ducks require higher quality feed, especially like to eat animal fresh feed, and young ducks often eat roughage, at this time no longer like to eat.

5) Laying ducks require a quiet environment and a regular life.

Normally, ducks lay eggs at 1:00 a.m. to 2:00 p.m., and the peak of egg production is in the early hours of the morning.

This is the time when the night is quiet and there is no noise, and it is best suited for the special requirements of breeding offspring. If the light is suddenly stopped or other stressors appear at this time, it will cause a riot and a crowd will appear. Except for egg laying, the duck house should also be kept relatively quiet, and strangers should not be allowed to enter or leave the duck house, so as to avoid other animals from scurrying in and out of the house.

In the management system, when to put ducks, when to feed, when to rest, to establish a stable law of life, such as changing the number of feeding, greatly adjusting the feed variety, will cause duck physiological disorders, resulting in production shutdown and reduction.

The annual egg production of Gaoyou Huchai Ma Duck is about 300, which is the duck species with the largest annual egg production in the country.

Gaoyou hemp duck is one of the three famous ducks in the country, produced in Gaoyou, Jiangsu Province, is a good breed in the Jianghuai region of China, and is a local excellent breed of egg and meat dual-use. Gaoyou duck is good at diving, resistant to rough feeding, adaptable, large egg head and good egg quality. In 2006, it was included in the "List of National Livestock and Poultry Breed Resources Conservation and Protection" by the Ministry of Agriculture.

It has successively won the honors of "National Geographical Indication Product" and "National Geographical Indication Trademark".

Gaoyou duck has been named as a product of the National Agricultural Standardization Demonstration Zone and a national product of origin, and in 2005, it was designated as a national livestock and poultry genetic resources protected breed and entered the national waterfowl germplasm resources gene bank.

The characteristic bai before the duck lays its eggs is, sitting.

The nest does not move, and will not get up until the egg is finished, and will not scream.

The characteristics of the duck before laying eggs are: the duck will sit in the nest and do not move, and only get up after laying the eggs, and do not bark.

1. If you want the duck to lay more eggs, you can use sake lees to promote eggs.

2. February and March in spring is the off-season for ducks to lay eggs, if you want to urge ducks to lay eggs, you must recuperate in winter, and you can add distiller's lees every day. Distiller's lees can increase the vitality of the ducks, make the ducks grow strong, and will lay eggs after the beginning of spring, making the duck's off-season to the peak season.

Generally speaking, there will only be two common diseases, one is to lay thin soft-shell eggs, and the other is prolapse, which may be because of the slippery cong Liang in the process of egg production, because the egg is too big or not as good as Zheng Yu, it will lead to such a situation, and it may also be due to the lack of trust and the lack of vitamins.

Producing Bo soft shell eggs, prolapse, hepatitis, influenza, duck plague, poultry friends jujube aspergillosis, pasteurellosis, etc. are the most common diseases during the laying of ducks, and the impact on duck hail and jujube is very large, we must pay special attention to the prevention and control work.

Common diseases include prolapse of the anus, soft shell eggs, avian aspergillosis, fallopian tube trauma, and osteomalacia.

Duck plague, trampling between ducklings, trampling after laying eggs, easy to suffocate after the volume ratio of the duck flock is too high, and may also breed bacteria, infectious diseases, etc.

There may be a pit breakout, there may be soft-shelled eggs, there will be a lack of vitamin D3, there can be a lack of calcium, and there may be some stress reactions.

1. Light: The light intensity of the laying period is 5 8 lux, such as the height of the bulb is 2 meters above the ground, generally per square meter of the duck house is calculated according to watts, about 18 square meters of duck house is equipped with a 25W bulb. In actual use, bulbs above 60W are usually not used, because the light distribution of large bulbs is uneven and it consumes electricity.

The principle of light entering the laying period is: only should be gradually extended, until it reaches 16 17 hours of light per day and night, not flickering and stopping, early and late, light intensity can not be strong and weak, only crescendo, otherwise the physiological function of laying ducks will be disturbed, affecting the egg laying rate.

A reasonable light system can make young ducks start laying in a timely manner, so that laying ducks can increase egg production; Unreasonable light system will advance or delay the sexual maturity of young ducks, reduce the production of laying ducks, and even cause moulting.

2. Temperature: The most suitable temperature for laying ducks is 13 20, at this time the egg laying rate and feed utilization rate are in the best state. Therefore, it is necessary to create conditions as much as possible, especially to do a good job of windproof and thermal insulation in winter, and provide an ideal temperature for laying eggs in order to obtain the highest egg production rate.

Ducks have egg-laying periods, the early and early (150 300) days, the middle (301 400) days, and the late (401 500) days, as well as the amount of diet and light. According to you, it's past the laying period.

Feed the fish often, go to the river often, take care of them diligently, and lay a lot of eggs.

When both egg cells mature and leave at the same timeFollicles make fun of laughterEnter togetherFallopian tubesWhen each part of the fallopian tube is encased in turn by proteins, shell membranes, and eggshells, a double yolk egg is formed. There are even times when multiple egg cells mature at the same time and merge into the fallopian tube together to become multiple yolk eggs. Similar to human fraternal twins.

but there is an essential difference.

Features of duck eggs. Gaoyou duck and Gaoyou duck eggs have a long reputation and endure, and the fundamental reason for this is their excellent quality and unique flavor. Gaoyou duck is also called sparrow because of the female feathers similar to sparrows, has strong physique, strong adaptability, deep diving, good at foraging for live food, eggs, meat and meat are used both, and the fat content is low in the special mountain containing points.
