Feeding and Management during Brooding Period Ducklings before arrival The brooding room is thoroughly cleaned and disinfected and fumigated and heated.
Adding multidimensional glucose to drinking water, drugs for preventing and treating chronic respiratory diseases can be used for 2 consecutive days. After the ducklings arrive on site, the time for water supply depends on the weather and transport time. When the transport time is long or the weather is hot, in order to prevent dehydration and extend the drinking time, the general Feed water after 1 hour to 2 hours, artificially induce drinking water in dehydrated or weak ducklings.
Feeding duckling pellets were fed freely for the first 3 days and fed from the 4th day onwards.
During the brooding period, the temperature of the brooding chamber is 28°C~31°C on the first day, and then decreases by about 1°C every day. The actual production observes that the distribution of the duck population in the duck house is determined, and is not distributed, evenly or in groups. The room indicates that the temperature is suitable. It should be noted that the temperature difference between the winter brooding room and the indoor temperature during the breeding period is a little larger, so a transitional temperature is needed so that the duck can only adapt to the temperature in the new environment after the transition.
The first week of brooding brooding requires light for 24 hours, and gradually transitions from 2 weeks of age to 17 hours per day. Once the light system is established, it must be strictly enforced.
The rearing period of breeding and management during the rearing period is 23 weeks from the 3rd week to the 25th. Therefore, the rearing and management of breeding ducks is particularly important. The level of rearing and management at this stage determines the level of future production performance. During the rearing period, the male and female ducks are preferably kept separately, which is beneficial to the weight control of male and female ducks. The Olbastar 76 ducks are generally grouped in proportion from 15 weeks to 18 weeks.
During the growth period, the control of the feed control material began on the 3rd day of the brooding period, which allowed the ducklings to weigh near the standard body weight curve from the very beginning. It also prevented the actual growth curve of the ducklings from wavy growth, affecting future growth and development. The control of the material is beneficial to the uniformity of the breeder ducks, and it can quickly reach the peak of production after the start of production. At the same time, the feed can be saved, the production cost can be reduced, and the incidence of leg problems and arch backs can be reduced.
Breeding weight control ducks must be weighed from the 3rd week, once a week, weighed on an empty stomach, and the number of weighed samples should be as large as possible (the number of gravid ducks should not be less than 10% to 15%). The statistical data is of reference significance. According to the actual body weight curve changes to control body weight, and integrate various factors to determine the amount of feeding, as far as possible to make the actual body weight curve close to the standard weight curve, if you are overweight, can not reduce the material, to maintain feeding, so that weight slowly increased, gradually The actual weight curve returns to the standard weight curve.
Breeding ducks during the growth period of 0 weeks to 6 weeks, the development is particularly fast, the individual differences are also more obvious, we must pay attention to tune the bar, call out overweight or too light ducks, keep alone, try to make the column even to achieve More than 80%. The standard body weight of each strain is summed up over many years and has strong reference value. It is necessary to make the duck body weight as close as possible to the standard weight curve. Breeding ducks can be reared in large groups with more than 500 per column, which is beneficial to improve the whole group. The uniformity of the duck.
During the breeding period, the open-type lighting should take into account the effects of natural light. From the third week of breeding ducks, it is guaranteed 17 hours of light per day (the sum of natural light and artificial light). The light intensity is half that of laying ducks, about 20 lux. Keep it up to 20 weeks and increase light intensity.
In order to prevent warts, to avoid turbulence and unsteady ducks, feed wastage, the Oxalon breeder ducks were generally cut off at 17 weeks, and half of the ducklings on the female ducks could be cut off. duck).
Egg-laying period management Preparation before laying eggs If male and female ducks are reared separately, they are grouped at 15 weeks to 18 weeks of age. Install egg nests at 21 weeks of age, measuring 45 centimeters deep, 40 centimeters wide and 40 centimeters high. Place an egg cartons for every 4 to 5 female ducks. Install the nested egg box in the lowest lighted area and place the eggs. The box should be fixed and cannot be moved.
The light illumination system starts from 21 weeks and gradually strengthens the light intensity, and the light intensity per day is required to reach about 30 lux (6 watts to 8 watts per square meter) by 25 weeks. Excessive light will cause the ducks to lose their hair and affect the species. Ducks produce eggs.
Duck production start time Octopus Type 76 requires the 21st week to begin feeding high-yielding ducks, and appropriately add feeds. Gradually increase gradually when feeding. Ducks will open eggs for 23 weeks. After seeing the eggs, we accelerated the discharge of the material so that the nutrients could be brought up in time. At the same time, the light was strengthened and the egg production rate at 25 weeks could reach 10%.
Weight control and restriction methods for laying ducks After ducklings are laid, they are weighed on an empty stomach. They are weighed continuously for 29 weeks and the dosage is determined based on the body weight. After 29 weeks, the eggs are weighed. The specific method of weighing eggs is: Eggs are weighed twice a week and each time more than one-third of the eggs of the batch of female ducks are qualified. Eggs are weighed several times during the high-yield period. If the egg weight does not change, the stable egg weight is used as the batch. The standard egg weight of the secondary duck (generally, the weight of the Olympia 76 eggs is 92 g to 93 g each), the daily feed amount at this time is the basic feed amount, and the egg weight will be weighed once a week and determined according to the egg weight change. The amount of feed this week; reminded in particular: ducks are particularly sensitive to aflatoxin, according to the author's experience, feed contains 15ppm aflatoxin, can cause a significant decline in female duck egg production, if not found and reload, Will cause the mother duck to lose hair and stop production. Therefore, in addition to disease, feed quality will directly affect production performance, and production must pay attention.
Egg-laying time The egg-laying time of the female duck is concentrated in the middle of the night from 3:00 to 5:00. With the extension of the egg-laying age of the female duck, the laying time is postponed and the winter is later. The first quail eggs are played at 5am-6am every day. Eggs produced on the playground and outside the nest should also be collected in a timely manner. The litter in the carton should be kept fresh, dry, and soft to ensure the cleanliness of the eggs and avoid contamination. The eggs should be sterilized immediately after they are collected, but be careful not to destroy the eggshell membrane. Eggs should be kept at room temperature 13 °C ~ 15 °C, relative humidity 75% ~ 78% of the environment, when storage eggs head down, large head (gas chamber) up, the shorter the storage time, the better, summer is best not to exceed It is better not to store more than 7 days in 3 days and other seasons. If the storage time is too long, it will have a greater impact on the hatching of hatching eggs.
In recent years, China's waterfowl industry has developed rapidly. According to statistics, there are currently 800 million ducks in China, accounting for more than 70% of the world's total duck population; nearly 300 million goose deposits, accounting for 88% of the world's geese population, ranking The first in the world is the world’s largest producer of waterfowl. However, the overall production level of China's waterfowl industry is not high. It is reflected in the feeding of large-scale meat ducks in the parental generation. Many farmers have a low egg rate, a high death rate, and high consumption of materials due to lack of scientific feeding and management techniques. The production cost reduces the benefits. This article takes the Obaixing 76 super meat duck which is one of the best species of waterfowl on the market as an example, and makes a brief summary of the main points of feeding and management for the reference of the farmers.
