Feeding method capable of increasing hatching rate of hatching eggs of meat ducks

Abstract

The invention discloses a feeding method capable of increasing hatching rate of hatching eggs of meat ducks. The feeding method comprises the following steps of: turning groups of the meat ducks at the age of 18 weeks; mixing groups of male and female ducks at the age of 20 weeks; adopting window opening type water-free dry feeding, wherein the feeding density is 3.6 ducks per square meter and the ratio of the male ducks to the female ducks is 1:4.8; illuminating for 17 hours every day; artificially feeding and picking up eggs; feeding with thick pad materials; and feeding each meat duck with200+ / -5 grams of mixed feed every day at the laying period of the meat ducks at the age of 28 to 75 weeks. The ducks are fed by the feeding method, the feed quantity of the meat ducks are controlled every day, and the methionine content, the lysine content, the vitamin E content, the niacin content and the biotin content of the mixed feed and the trace element selenium content are controlled, so that the average weight of the egg is controlled to be 90 to 92 grams, the egg quality meets the nutritional requirement and the laying rate, the healthy embryo development under the same hatching condition is benefited, the hatching rate and the healthy duckling rate are greatly increased, the quality of the newborn ducklings is improved, and the dead embryo rate of the hatching eggs is reduced.

Description

technical field [0001] The invention relates to a feeding method, in particular to a feeding method for improving the hatching rate of breeding eggs of meat breed ducks. Background technique [0002] At present, the breeding methods of meat ducks basically follow the methods provided by foreign breeding manuals. The characteristics of this feeding method are: excessive nutrition and ad libitum feeding. This is not only a waste of feed, but more importantly, due to high nutrition and large feed intake (230-240 grams of free food per day), the weight of duck eggs produced is large (generally 97 grams, or even more than 100 grams) and the quality of breeding eggs is poor. As a result, the hatching index is low (hatching index: the hatching rate of hatched eggs≤83%, the hatching rate of fertilized eggs≤90%, the healthy chick rate of fertilized eggs≤87%). The current way of raising ducks is to adopt natural rivers and lakes in the south, and to imitate the feeding mode in the s...

This is not only a waste of feed, but more importantly, due to high nutrition and large feed intake (230-240 grams of free food per day), the weight of duck eggs produced is large (generally 97 grams, or even more than 100 grams) and the quality of breeding eggs is poor. As a result, the hatching index is low (hatching index: the hatching rate of hatched eggs ≤ 83%, the hatching rate of fertilized eggs ≤ 90%, the healthy chick rate of fertilized eggs ≤ 87%)

The current way of raising ducks is to adopt natural rivers and lakes in the south, and to imitate the feeding mode in the south, digging a pool in the sports field to allow the ducks to bathe naturally, but this mode has a big disadvantage. The water is passed through the mouth or feces of the diseased ducks. Excreted into the water, especially the water polluted by viruses such as avian influenza and Newcastle disease, and infected by healthy ducks bathing in the mouth through the mouth; in addition, bathing ducks in water wastes a lot of water resources, and the discharge of polluted water causes environmental damage.
