Factors affecting egg production in ducks
From the beginning of sexual maturity, male and female ducks enter a new stage. During this stage, the male ducks must be mated to breed. The female ducks must breed eggs. The growth and development of all parts of the body has basically ended, and all its activities are surrounded by "breeding." "This center, all kinds of feeding management work must also serve this center, do everything possible to create a continuous high production and stability of the environment and conditions to obtain high-quality eggs.
Variety factors
Variety is a prerequisite for high yields. The level of egg production, the length of the laying cycle, the persistence of egg production, and the size of the eggs all have a close relationship with the variety. If you can choose a good breeding breed, egg production can be a few, even doubled, and economic efficiency will also increase. How to select the most suitable species for local rearing depends on their own feeding conditions and management techniques. This is a key factor in the success of breeding.
Nutritional factors
After entering the laying period, the demand for nutrients in ducks is higher than at any previous stage. Apart from the nutrients necessary for the maintenance of life activities, a large amount of nutrients necessary for laying eggs are also required. Such as energy, protein, calcium and other nutrients must be fully supplied. Otherwise it will affect the egg production rate.
To reach the level of sustained high yield, in addition to breed is an innate factor, whether the nutrients in the diet are comprehensive and balanced, and whether the quantity can meet the needs, this is a necessary condition for maintaining high production and stable production.
envirnmental factor
Environmental factors are more complex, and the most important factors affecting egg production are light and temperature.
1, lighting
The length of light time for laying ducks is also related to laying eggs. The main role of light is to promote the mature ovulation of follicles. Therefore, in the incubation period, the control of the light time is aimed at preventing the young ducks from becoming too precocious; when entering the laying period, the lighting time should be gradually increased and the light intensity should be increased in order to promote the development of the ovary and achieve timely production and enter the production of eggs. After the peak period, the lighting system (light hours and light intensity) should be stabilized in order to maintain continuous high yields. The light intensity during the laying period is 5-8 lux. For example, if the height of the bulb is 2 meters away from the ground, generally, the duck house per square meter is calculated as 1.3-1.5 watts, and about 18 square meters of duck houses are loaded with a 25-watt bulb. In practice, light bulbs of more than 60w are generally not used, because large bulbs have uneven light distribution and power consumption. Fluorescent lamps are greatly affected by temperature and are generally not used. The light bulb must be covered so that the light shines on the duck instead of the ceiling. There are many dusty ducks, and the light bulb should be wiped regularly to keep it clean so as not to get dust and affect brightness.
The lighting effect usually takes 7 to 10 days to be displayed. Therefore, during the production period, it is not possible to suddenly increase the number of hours of illumination or increase the light intensity because it does not achieve immediate results. In general, each increment does not exceed 1 hour, and it is stable after 5 to 7 days.
The principle of light entering the production period is: only gradually extended until reaching 16-17 hours of light every day and night, can not be ignored according to Hugh, suddenly morning and evening, light intensity can not be strong, weak, only gradually stronger, otherwise it will The physiological function of laying ducks is disturbed and the egg production rate is affected.
A reasonable lighting system can enable young ducks to start production in a timely manner so that laying ducks can increase egg production. Irrational lighting system will advance or delay the sexual maturity of young ducks, reduce the production of ducks, stop production, and even cause moulting. .
2, temperature
The optimum temperature for laying ducks is 13 to 20°C. At this time, the egg production rate and feed utilization rate are in the best condition. Therefore, it is necessary to create conditions as far as possible, especially in winter wind insulation work, provide an ideal temperature of the egg production environment in order to obtain the highest egg production rate.
Health factors
Without a healthy body, it is impossible to achieve high yields. Therefore, at the stage of cultivating young ducks, prevention of major communicable diseases should be done well. After entering the stage of laying eggs, environmental sanitation and feeding management should be improved, disease resistance should be increased, and the occurrence of diseases should be minimized so as to maintain high and stable yields. .
Washable Underpads are reusable pads that are designed to protect
mattresses, chairs, and other surfaces from urine, sweat, and other
bodily fluids. They are made from absorbent materials such as cotton,
polyester, or a combination of both, and have a waterproof backing to
prevent leaks.
Washable underpads come in a variety of sizes and absorbency levels, and
can be washed and dried in a standard washing machine and dryer. They
are a cost-effective and environmentally friendly alternative to
disposable underpads, and are ideal for individuals with incontinence
issues, bedridden patients, and those who are recovering from surgery or
illness.
Some washable underpads also feature antimicrobial properties to prevent
the growth of bacteria and odors, and others have non-slip backing to
keep them securely in place. They are easy to use and maintain, and can
provide peace of mind and comfort for both patients and caregivers.
