Management of Cherry Valley SM3 Large Parent Ducks


1. During the rearing period (4-18 weeks), feeding and management?
(1) The significance of the growth period:
The purpose of the breeding period is to keep the weight gain of the duck group as close as possible to the target weight, because too much weight is harmful to the subsequent egg production and fertility rate of the duck group. The daily feed volume should be determined by the difference between the duck population weight and the target body weight. ?
(2) Check weight and limit the feeding method:
Before feeding on the 28-day-old morning, each column is called 10% of the male and female ducks. The average weight of the ducks in each bar is calculated and compared with the weight curve in the rearing period, and then the amount of feed required in each bar is used as the feed. After the first day of the week, the body weight was checked and the difference between the actual body weight and the target body weight was used to determine the amount of this week's feeding. This amount was unchanged for a week to ensure that the duck body weight was as close as possible to the target curve. ??
If the 28-day-old body weight is low, the 28-day-old feed is fed to the 35th day of age. ??
If the 28-day-old body weight is high, the 21st-day feed is fed to the 35th day of age. ??
If the 28-day-old body weight is the same as the target body weight, the 25-day-old feed is fed to the 35th day of age. ??
Before the 35th day of feeding in the morning, the male and female ducks were again tested for body weight and compared with the target body weight. If the target was reached, the feeding amount was unchanged, and if the target was lower than the target, it was increased by 5-10 grams of feed. If the target is higher than the target, continue to observe the week. After the target is still higher than 5 to 10 grams to reduce the amount of feed. ??
Matters needing attention: The first thing every morning is to feed the ducks, weigh each column separately, and then put it into the feed trough or spread evenly on the indoor grass mat or on the sports ground, so that each duck can eat the feed at the same time . Feed during the breeding period once a day, but no water shortage at any time. ??
If the female duck body weight meets the target and the male duck body weight is too low, increase the feed slightly to ensure the body condition of the male duck without excessively increasing the body weight of the female duck.
(3) Dividing into sexes?
Accurately controlling body weight during the breeding period is the key to obtaining the best breeding effect. ??
The cherry of the Cherry Valley SM3 is a hybrid strain carefully selected from the standpoint of heritability and carcass characteristics. The female duck is a hybrid strain that was bred from the perspective of egg production. Therefore, there is a big difference in potential weight between males and females. ??
In order to accurately control the growth weight of these two different system ducks, the male and female ducks were reared in groups before the age of 18 weeks. In addition, special attention needs to be paid to the fact that a small amount of female ducks must be mixed in the male duck group in order to make the male ducks have “sexual memories” during the growth process. These female ducks are often called “printing female ducks”. In short, don't be able to keep the ducks alone without the companion of stamping the ducks. Otherwise, the fertilization rate will decrease. Both the female duck and the female duck are fed the same amount of feed, but the mother duck is not measured. ??
From the first day of age, male ducks were reared in groups of 4.5 ducks and one female duck, and the remaining female ducks were reared separately (fed). During the 28 days of brooding, feed on a fixed daily basis. From 28 to 18 weeks of age, male ducks are fed according to the target weight of the male duck. Feeding the female duck according to the target weight of the female duck does not need to weigh the imprinted female duck in the male duck column and does not require weight control. ??
At 8 weeks of age, the male and female ducks were mixed together in a ratio of 1 male to 5 females. The imprinting female ducks in the drake bar are evenly distributed in each production stall. These female ducks will also produce a considerable number of eggs. ??
The male and female ducks were mixed in proportion and the duck population was fed with the feeding amount of the male duck at the age of 17 weeks. In this way, it actually increases the feeding amount of female ducks. ?
Note: The breeding and breeding of ducks by sex must be strengthened in feeding and management, especially the management of male ducks. Do not forget that “printing the female duck” must be essential, otherwise it will seriously affect the fertilization rate of the breeding duck eggs. In addition, male and female mixing time can be performed at any time during the 18-20 weeks. ?
2, feeding and management of the egg production period?
(1) Feed Management:
18-week-old male ducks and female ducks are mixed in a ratio of 1:5 until the end of the laying period. The 18-week-old mixed group simultaneously converted the growth period feed to the egg-laying period feed. At this time, the male and female ducks have been mixed and raised, and the feeding amount of the female duck has been increased to the feed amount when the male duck is 17 weeks old. At the same time, each duck added 5 grams of feed per day to gradually increase the free food intake to 19 weeks of age. After the 18th week of age, due to the increase in the amount of feed, the ground feeding method should be gradually transferred to chute feeding. ?
From the age of 19 to 75 weeks of age, feed tanks are used to provide feed during the laying period so that the ducks can eat freely. ??
(2), litter management:??
The floor litter must be kept clean and dry to ensure the cleanliness of the eggs and reduce the contamination of ducks and hatching contamination. ?
(3) Egg Nest Management:
Nests are the basic conditions for ensuring that most eggs are produced in a good environment. The cleaner the litter of the nest box is, the cleaner the eggs are and the higher the hatching rate is. The nests were made of wood or masonry with a 40 cm square inside diameter, and each nest was used for laying eggs for 3 females. Set the number of nests based on the number of female ducks. Ducks must provide nests at 20 weeks of age. ?
(4) Collection of eggs:
Collecting eggs is the first job every morning. The shorter the eggs stay in the duck house, the less pollution they have. When all the eggs are collected, record the number of eggs per day on the card. If the daily eggs are reduced by 10% from the previous day, check the duck bar first to see if there are any omissions. If the number of eggs after the check is still low, you should find other reasons. In order to avoid broken eggs and bacterial contamination, eggs are collected and stored in egg trays, disinfected and placed in stock for hatching. ?
(5) Sports Ground Management:
The open duck shelter should take a arbor in the playground to avoid direct sunlight in hot seasons and reduce high temperature stress. Bathing water is best changed once a day. ?
