Uniformity refers to the uniformity of the development and development of the ducks, including body weight, body condition, and sexual maturity. To improve the uniformity of the ducks, comprehensive measures must be taken. Cherry Valley parent breeding ducks, whole brooding, weight control during the breeding period, It plays a vital role in the production of eggs for parental breeding ducks.
A scientific and reasonable breeding and feeding program.
1, 0-28 days old feeding.
The feeding amount of 0-28 days is based on the standards recommended by the manual. According to the weather and seasonal conditions, the ducks of 0-3 days old should be free to eat, so that the ducklings can get the energy needed, after 3 days old. According to the 28-day feeding table, according to the season and weight, the male duck can be as high as the standard 3g, the female duck can be higher than the standard 2g, the digestive function of the duckling and the digestive organs are weak, and the ducklings cannot be full, need to be divided. The second feeding, that is, the first 3 days of free feeding, 8 times / day after 4 days. Reference is made to 6 times/day of 2 weeks, 4 times/day of 3 weeks of age, 2 times/day of 4 weeks of age, 2 times/day of 4 weeks of age, and finally to one feed.
2, five weeks of feed amount.
After five weeks, the feeding adjustment was based on the weight of the duck. After 4 weeks, the fasting was performed at the same time every week. When weighing, the small group was sampled and weighed. According to the growth of the weight, the materials of the previous few days were used. The amount is adjusted to determine the amount of feed for the next day, and then adjusted according to the weight of the 4th week.
1) When the average body weight is higher than the standard weight or the weight gain is large, the 26-day-old feed amount is taken.
2) The average weight is lower than the standard weight or the weight gain is small, and should be properly added about 2g.
3) When the average body weight is consistent with the standard body weight or the weight gain is ideal, the feed amount is maintained for 28 days.
3, the amount of feed in the breeding period of 6-18 weeks.
According to the weekend weighing and weekly weight gain, the feeding is determined and the weight control is done.
1) Weight control principle:
Fat ducks above the standard weight can not be transitioned too quickly. Individual differences must be considered to ensure a certain weekly weight gain. For ducklings that do not meet the standard weight, they cannot be fertilized in transition, and there must be 3-4 weeks of adjustment time.
2) Reasonable feeding
The range of feeding is determined according to the specific conditions of the ducks, the different stages, the seasons and the ambient temperature.
The 0-5 week duck population is weak, and the feeding can not be too strict. The requirement is higher than 3-5g, the female duck is about 3g, and the male duck is about 4g. The weekly feeding range is 4-7g for 9-12 weeks, the female duck is no more than 5g, the male duck is no more than 7g, the reproductive system is just developed after 13-15 weeks, the feeding may be slightly added, and the reproductive system is prosperous in 16-23 weeks. In preparation for the addition of light stimulation, the feeding range will be 3-12g. It was added twice a week.
Note: The feeding is stable every week. Do not feed too fast during the breeding period. Otherwise, it will lead to overweight after 10 weeks. If you don’t dare to feed, the weight gain will not reach the standard, and the feeding will be too fast in 6-8 weeks, which may lead to an increase in the chance of kicking. Feeding must determine the standard weight and weekly weight gain. Consider a large group weighing between 8-10 weeks if the group uniformity is low.
Three scientific feeding management.
1 Uniformity starts from the 1st day of age, mainly from the uniformity of drinking and starting food, giving enough attention.
2 During the breeding period, the ducks will be divided into large and medium-sized ducks for daily adjustment, and individual ducks will be specially treated.
3 According to the age of the ducks and the amount of feed, increase the drinking water and take the area.
3 Do a good weekly weighing and follow-up weighing of the big duck.
