Feed reducing the death and culling rate of medium-sized and big ducks in summer and a preparing method thereof

Abstract

The invention relates to the technical field of agriculture breeding, and particularly relates to feed reducing the death and culling rate of medium-sized and big ducks in summer and a preparing method thereof. Raw materials of the feed include corn, millet, full-fat rice bran, a premix, first-leaching soybean meal, golden-rod, bone meal, stone powder, fungus phytase, calcium hydrophosphate and calcium carbonate. Compared with the prior art, the feed and the method are advantageous in that: through synergistic effects of different raw materials in the premix, the feed allows the medium-sized and big ducks to have high heat resistance and to stay calm in a summer breeding process; the ratio of the raw materials in the premix is changed continuously along the application of the feed so that a stable feed intake amount and stable growth performance are maintained along with temperature changes in the breeding process; when a heat stress reaction occurs, the raw materials in the feed are changed timely to achieve a real-time control function; addition of the raw materials does not cause adverse influences on meat quality or nutrition of the bred ducks; the death and culling rate of bred ducks in summer is reduced; the feed-meat ratio is reduced; and the comprehensive benefit is increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and in particular relates to a feed for reducing the dead rate of medium and large ducks in summer and a preparation method thereof. Background technique [0002] my country is a big country for raising ducks. According to incomplete statistics, my country's duck meat production accounts for 75% of the world's total output. In recent years, with the adjustment of industrial structure and the rapid development of waterfowl industry, epidemic diseases are also increasing. In addition to the need to prevent and control epidemic diseases, Due to the special physiological structure of ducks, the dense down feathers and well-developed tail fat glands can effectively waterproof and keep out the cold. At the same time, it also has the problem of poor heat resistance, especially for individuals with large and thick fat. During the month (the average temperature reaches 32°C), the feed-to-weigh...

[0002] my country is a big country for raising ducks. According to incomplete statistics, my country's duck meat production accounts for 75% of the world's total output. In recent years, with the adjustment of industrial structure and the rapid development of waterfowl industry, epidemic diseases are also increasing. In addition to the need to prevent and control epidemic diseases, Due to the special physiological structure of ducks, the dense down feathers and well-developed tail fat glands can effectively waterproof and keep out the cold. At the same time, it also has the problem of poor heat resistance, especially for individuals with large and thick fat. During the month (the average temperature reaches 32°C), the feed-to-weight ratio of medium and large ducks increases compared with normal temperature, and the mortality rate is also higher, reaching about 4.17%. However, the existing feed only improves how to increase the growth rate, so , further research should be conducted on the heat tolerance of medium and large ducks
