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 ...
