How to raise egg ducks

Egg duck brooding feeding management and meat ducks are basically the same, in the breeding period should be taken to mild restriction of feeding, appropriate more green, roughage, or in the original mixture of meal, mixed into a portion of rice after mixing wet feeding, feeding twice a day, to ensure that each duck can eat the feed at the same time, to avoid hunger and satiety is not uniform. At the same time, it is necessary to strengthen the movement, promote the development of bones and muscles, and prevent over-fertilization. Low light lighting at night 30 to 40 square meters of duck house with a 15-watt electric lamp lighting, natural light during the day. According to the habits of ducks, regular work and rest, the development of operating procedures, try to maintain stability, do not often change. Laying ducks after the start of the various stages of management is different, so after the start of 300 days of age is divided into the pre-laying, and then to 400 days of age for the middle of the laying, 400 days of age to 500 days of age for the late laying. Pre-laying stage should be pushed to the peak of egg production as soon as possible, in terms of nutrition should be based on the rising trend of egg production, increase the nutritional concentration of the ration, and appropriately increase the number of feeding meals, in addition to continue to feed 3 meals during the day, at night, before turning off the lights to feed an additional meal, the average amount of concentrate intake of each duck is about 150 grams. Light time should reach 17 hours, artificial light, the time of turning on and off the light should be stable, can not be changed arbitrarily. Whether the management of this period of time is appropriate, should be observed from the following aspects: the first laying eggs egg weight is light, but with the increase in the age of the egg weight increases, to 230 ~ 250 days of age when the egg weight should reach the standard egg weight of the breed; and the egg production rate is rising, at 230 days of age, the egg production rate should reach about 90%; 210 ~ 300 days of age, 10% of the mama ducks randomly selected each month to determine the If the body weight is maintained at the original weight, it means the feeding management is just right. On the contrary, if the egg weight does not increase quickly or low down again; the egg production rate is sometimes high and sometimes low, or even a continuous decline; a large increase or decline in the body weight of the mama ducks indicate that there is a problem with the feeding management, and the reasons should be found out in time to improve it. After more than 100 days of continuous egg laying, into the middle of egg laying, at this time the physical consumption is greater, the health condition is not as good as the pre-laying period, a little carelessness in feeding management, the egg production will decline, and even appear feathering, which is more difficult to raise the stage. This stage of feeding strive to keep high yield, so that the peak egg production as long as possible, in this stage is first of all in the nutrition to ensure that to meet the needs of high-yield, nutritional level than the previous stage slightly increased, with the feed of crude protein 19.5% to 20%. With the increase in age, the utilization rate of calcium in egg ducks has slightly decreased, and the amount of calcium fed should be increased appropriately by adding 1% to 2%, 1 to 2 mm in diameter granular limestone (or shells) to the compound feed, or putting a separate pot in the duck house with the above specifications of shells or limestone granules, and letting them feed freely. When the temperature is below 5℃, it should be insulated and warmed up, and when it exceeds 30℃, it should be prevented from heatstroke and cooled down. Whether this stage of management is appropriate needs to be observed from the following aspects: such as shell eggs smooth and thick, glossy; production time is concentrated, in the morning 2 ~ 4 hours of egg laying; ducks energetic, long diving time after the water, out of the water after the feathers are smooth and not wet. This indicates proper feeding management. On the contrary, if the egg shape is long, thin shell, sand points, and even soft-shelled eggs; ducks appear every day to delay the egg-laying time, or even in the daytime egg laying, egg laying sparsely, very scattered; ducks lack of spirit, weak action, wet feathers after going into the water, and even sinking. The above situation shows that the feeding management is not appropriate, should promptly find out the reasons, to improve. 400 days of age into the late egg-laying, this stage should be based on the weight of ducks and egg production rate to determine the quality of feed and feeding. If the egg production rate of ducks is still more than 80%, and the ducks' body weight has a slight tendency to decline, in the feed should be appropriate to increase the animal protein feed; if the egg production rate is still about 80%, the body weight has a tendency to gain weight, it is appropriate to reduce the metabolic energy in the feed, or increase the feeding of green and roughage; if the body weight is normal, and the egg production rate is also high, the protein in the feed is slightly higher than the last stage; if the egg production rate has been reduced to 60% or so If the egg production rate has dropped to about 60%, it is difficult to increase the egg production rate at this time, and there is no need to increase the feed. In the management of more put less off, promote movement; light time can not be reduced, operating procedures to maintain relative stability, to avoid all sudden stimuli and cause stress.
