Optimum elimination time for ducks
In the rural areas, some duck farmers raise ducks and ducks, generally raising them for three or four years, or even raising them to natural old age, and they are reluctant to eliminate them. As everyone knows, long-term feeding ducks consume about 150 grams of feed every day, but few eggs are produced, and even eggs do not produce, which reduces the economic benefits of the entire duck population. So, when is the most suitable duck duck raised?
According to the best laying age of laying ducks, from the 120th day after hatching, the production starts. The egg production in the first laying year is the highest, and usually goes down by 5 to 10% in the second laying year. By the third egg production year, it will fall by 10 to 15%. Laoyai's activity is not strong, it is difficult to grazing and feeding, poor adaptability to climate change, feed consumption and low utilization rate. Also producing 1 kilogram of eggs, the old duck consumes about 20% more feed than the new duck.
According to the egg laying characteristics of laying ducks, the feeding and management of the first laying year should be strengthened so that the entire duck group can exert its maximum production potential within the optimal production period. After the first year of production, it is necessary to selectively eliminate them based on the laying conditions of laying ducks, removing low-yield individuals and retaining high-yield individuals. Even if the egg production is low, do not immediately eliminate the new ducklings that were cultivated in the spring, because only two months of eggs may have been produced due to the natural environment. If the management is strengthened in the coming year, egg production may be significantly increased. rise. When ducks are raised to 500-600 days of age, it is necessary to determine whether ducks need to be preserved according to the market price of duck eggs and feed. If the sales revenue of duck eggs is greater than the feeding cost of old ducks, the entire duck population can still be kept; otherwise, it will be shown that feeding these duck groups is no longer profitable and all old ducks should be eliminated.
