Can laying duck feed fatten ducks?
Of course. Feeding laying ducks depends on four feeding methods: 1. Feeding according to the weight and laying rate of laying ducks determines the quality and feeding amount of feed: (1) The laying rate of ducks is still above 80%, while the weight of ducks tends to decrease slightly. At this time, animal feed should be properly added to the feed (fresh snails are better); (2) When the ducks gain weight, their bodies tend to get fatter, but the egg laying rate is still 80%. Therefore, coarse feed and green feed can be appropriately increased, or the feed intake can be controlled (1.50g/ day), and the feed intake can be reduced by 50% according to the free feed intake, so that the ducks can't eat too much concentrate, but the animal protein feed should be maintained at the original level or slightly increased. (3) Normal body weight and high egg laying rate, and the protein level in feed can be slightly improved compared with the previous stage; (4) The egg laying rate is reduced to 60%, which is difficult to improve, and feeding is not needed. Second, look at dung feed. If the manure is thick, soft, strip-shaped and shiny, it can be divided into several sections by tapping with your feet, which shows that the fine, coarse and green materials are reasonably matched. If the feces are small and firm, the color is black, and the cross section is granular after pulling, it means that there is too much feed in the concentrate feed and too little feed in the green feed, and the digestion and absorption are abnormal. Therefore, it is necessary to reduce the feeding of concentrated feed and increase the feeding of green feed. If the feces are light in color and shapeless, they will be scattered in one row, indicating that the concentrated feed is insufficient and the nutrition is low, so it is necessary to supplement the concentrated feed. If the feces are yellow-white, gray-green and smelly, it means that the ducks are sick and should be treated in isolation. 3. If the egg shape of the laying feed is abnormal and small, it means that the nutrition is insufficient. Feed rich in protein should be added, such as bean cake, peanut cake, fish meal, etc., so as to increase the crude protein content of the diet to 20% and appropriately increase the total amount of the diet. If the eggshell is thin, translucent, trachoma, rough and even produces soft-shelled eggs, it means that the feed quality is not good, especially calcium or vitamin deficiency. Feed rich in minerals and vitamin D such as bone powder, shell powder and lime powder should be added. For example, cod liver oil and inorganic salt additives can be added when eggs lose weight. If the spawning time is concentrated at two in the morning, it means that the feeding method is correct. If laying eggs is delayed every day and the egg body becomes smaller, it is necessary to increase the feed. Fourth, look at healthy ducks with psychological feeding and high egg production rate. They are energetic and dive for a long time. After landing, their feathers were smooth and not wet, and the water splashed everywhere. If the duck is listless, can't move, and dare not go into the water after being released, its feathers will become sticky or even sink after going into the water, indicating a lack of nutrition. They should be fed fresh animal feed in time, supplemented with cod liver oil (preferably clean cod liver oil) and mixed with powder. A course of treatment is to give each duck 1 ml every day, and stop feeding for 7 days for 3 consecutive days, or feed each duck 0.5 ml every day for 650 consecutive days.
