Problems solved by technology

At the same time, a large amount of soybean meal is used as protein raw material. The contained soybean lectin, antigen protein, trypsin inhibitor, etc. will cause acute damage to the intestinal tract, which will seriously affect diarrhea and nutrient absorption rate, increase the incidence rate and seriously reduce production performance.
At the same time, exogenous oils such as soybean oil are added, because the intestinal tract of ducklings is not fully developed, the content of lipase is low, and the absorption and utilization rate is very low
Based on commercial low-price competition, there is currently no fundamentally different feed based on improved performance and reduced morbidity

Embodiment 1

[0018] A pre-feed for meat ducks, calculated as air-dried mass percentage, including the following components: expanded corn 35%, broken rice 17%, flour 5%, blood globulin powder 3%, corn gluten meal 5%, and expanded soybean 23% , Egg yolk powder 2%, calcium hydrogen phosphate 1.5%, stone powder 1%, fine bran 5.1%, lysine hydrochloride 0.35%, methionine 0.05%, premix additives 2%.

[0019] This example contains 20.4% crude protein, 7.27% crude fat, 0.86% calcium content, 0.59% phosphorus content, metabolizable energy 3080kal / kg, and a reasonable ingredient distribution ratio.

[0020] Using this example and the control group in a comparative test in Jiangmen, Guangdong, there were 9,000 Cherry Valley meat ducks. The experimental diet was used from birth to 12 days. The average initial weight of the duck was 57g, the average final weight at 12 days was 420g, and the feed to meat ratio was 1.31. The survival rate was 97%, and the observed diarrhea rate was about 0.5%. Com...

Embodiment 2

[0024] A pre-feed for meat ducks, calculated as air-dried mass percentage, including the following components: expanded corn 25%, broken rice 27%, flour 6%, blood globulin powder 3%, corn gluten meal 5.5%, and expanded soybean 21% , Egg yolk powder 1.5%, calcium hydrogen phosphate 1.5%, stone powder 1%, fine bran 6.15%, lysine hydrochloride 0.3%, methionine 0.05%, premix additives 2%.

[0025] This example contains 19.94% crude protein, 6.57% crude fat, 0.86% calcium content, 0.58% phosphorus content, metabolizable energy 3060kal / kg, and the composition ratio is reasonable.

[0026] Using this example and the control group in the Guangzhou area of ​​Guangdong Province, there were 7300 cherry valley ducks. The experimental diet was used from birth to 12 days. The average initial weight of the duck was 57.3g, and the average final weight on the 12th day was 421.5g. 1.32, the survival rate was 98.3%, compared with 5000 cherry valleys fed the control group, the initial weig...

Embodiment 3

[0030] A pre-feed for meat ducks, calculated as air-dried mass percentage, including the following components: puffed corn 27%, broken rice 28%, flour 4%, hemoglobin powder 2%, corn gluten meal 4%, and puffed soybean 25% , Egg yolk powder 1%, calcium hydrogen phosphate 1.5%, stone powder 1%, fine bran 4.1%, lysine hydrochloride 0.35%, methionine 0.05%, premix additives 2%.

[0031] This example contains 19.4% crude protein, 7.07% crude fat, 0.86% calcium content, 0.59% phosphorus content, metabolizable energy 3120kal / kg, and the composition ratio is reasonable.

[0032] In Zhaoqing, Guangdong, this example was compared with the control group. 4000 Cherry Valley meat ducks were used in this experiment from birth to 12 days. The initial average weight of the duck was 56.8g, and the average final weight at 12 days was 423.3g. 1.33, the survival rate was 97.4%, compared with 7000 cherry valleys fed the control group, the initial weight of ducks was 59.1g, the average final ...

Abstract

The invention discloses an earlier-stage meat duck feed for improving the productivity. The feed is prepared from the following components in parts by weight: 20-40 parts of extruded corns, 10-30 parts of broken rice, 0-10 parts of flour, 0-5 parts of spray-dried blood cells, 0-6 parts of corn gluten meal, 15-30 parts of extruded soybeans, 0-5 parts of yolk powder, 1-2 parts of calcium hydrogen phosphate, 0.5-1 part of rock powder, 3-10 parts of fine rice bran, 0.1-1 part of lysine hydrochloride, 0-1 part of methionine and 2 parts of a premix compound additive. The meat duck earlier-stage feed disclosed by the invention is obtained by mainly adjusting the types and composition of the feed raw materials according to a formula, can effectively improve the weight of a meat duck of 12 days and reduce the diarrhea rate, and meanwhile can increase the survival rate and increase the growth and development of feather.

Description

Technical field [0001] The present invention relates to the field of feed, and more specifically, to a pre-feed for meat ducks with improved production performance. Background technique [0002] The annual breeding volume of cherry valley ducks in Guangdong is more than 500 million, and there are 120 million in Guangxi. Due to the early market competition, the nutritional demand for feed is low, especially in recent years, the incidence of meat ducks is higher. Your physique also has a lot to do with it. In South China, the pre-feed for meat ducks is generally used from 0-12 days, and the post-feed for meat ducks is used until the 12th day. The current formula raw materials are generally corn and soybean meal, and some fish meal and soybean oil are added at the same time. There is a certain degree of science and low cost, but it also has its drawbacks. [0003] A large amount of corn is used as an energy raw material in the early feed of meat ducks. The inhomogeneity of corn ...
