News briefing： The dietary nutrient level of Cherry Valley ducks in different growth stages of Cherry Valley duck should be higher than that of common ducks
The dietary nutrient level of Cherry Valley ducks in different growth stages of Cherry Valley duck should be higher than that of common ducks, and should be at full price, and the combination of crude protein and metabolic energy should be considered in different populations under various environmental conditions. Ducklings stage: usually requires crude protein content of 23-24% , metabolic energy 2700-2800 kcal/kg.
The amount of green fodder can account for 20% of the diet. Free Food intake throughout the day. Medium Duck stage: can use a lot of green roughage, crude protein content is 16-20% , metabolic energy 2800-2900 kcal/kg. Feed 3-4 times daily. If it is half-house feeding and half-grazing, depending on the grazing situation, feed as appropriate 1-2 times, one of which should be a grain feed. Duck stage: to formula feed-based. The general requirement of crude protein content 16-18% , metabolic energy 2700-2800 kcal/kg. The daily dosage of formula feed is 4 taels, three times a day, such as half-house semi-grazing, feed formula feed 1-2 times a day.
According to the source of feed, the following formula (%) can be adopted for different growth stages: 0.3 age adjustment: Corn 50, Rice Bran 8, soybean cake 17, peanut bran 10, Wheat Bran 4, freshwater fish meal 8.2, bone meal 1.5, Salt 0.3, Micronutrient 1, plus 10g of animal vitamin powder. 4-8 weeks of age: Corn 50, Rice 10, Rice Bran 10, soybean cake 5, peanut bran 10, wheat bran 5, freshwater fish meal 7.2, bone meal 1.5, Salt 0.3, Micronutrient 1, plus animal vitamin powder 10g. 9-20 weeks of age: Corn 30, Rice 30, Rice Bran 18, SOYBEAN CAKE 3.7, wheat bran 5, Peanut Bran 8, freshwater fish meal 3, bone meal 1, Salt 0.3, Micronutrient 1, plus 5g of animal vitamin powder.
Early egg laying: Corn 45, Rice 5, Rice Bran 8, soybean cake 11.7, peanut bran 10, wheat bran 5, freshwater fish meal 9, bone meal 2, Shell meal 3, Salt 0.3, Micronutrient 1, methionine 0.1, plus 10g of animal vitamin powder. Peak laying period: Corn 45, Paddy 5, Soybean cake 17.5, peanut bran 10, wheat bran 5, freshwater fish meal 10, bone meal 2, Shell powder 3.5, salt 0.3, Micronutrient 1, methionine and methionine 0.1 each. Production period: Corn 35, Rice 30, Rice Bran 10, soybean cake 5.2, peanut Bran 7, Wheat Bran 5, freshwater fish meal 4, bone meal 1.5, Shell Powder 1, Salt 0.3, Micronutrient 1, plus 7g of animal vitamin powder.
If the conditions for self-preparation are lacking, the existing feed may also be purchased: 1-15 days of age for commercial imported chicken feed, 3 weeks of age for meat chicks produced by the feed company, 3-8 weeks of age for egg chicks, after 8 weeks of age, the body weight of about 6 catties, can be fed medium chicken feed
