2. The Dezhou donkey can enter the fattening period after a 6-day transition period. Roughage cereal grass, cottonseed husk, soybean straw and corn straw are fed freely, and the mixed concentrate is fed 3.5-4 kg per day, which is composed of cottonseed cake or soybean meal, peanut cake 50%, corn flour 29%, wheat bran 20%, salt 1%, and 20 grams of sodium bicarbonate per day.

3. During the fattening period of Texas donkey, exercise should be restricted, clean drinking water should be provided, donkey body should be brushed every day, and the enclosure and surrounding environment should be kept dry and hygienic. It can be slaughtered after fattening for 60 to 70 days.

The young donkeys of Dezhou donkeys are fattening.

1. The donkeys purchased are dewormed first, not castrated, and raised in grooves according to sex and weight.

2. The newborn donkey ate colostrum for 6 days, breast-fed after 7 days, and trained to eat gruel made from corn, wheat and millet at the age of 15 days. Add a little sugar to induce the donkey to eat and feed 15-20 grams a day.

3. After 22 days of age, the mixed concentrate was fed 80kg 100g. The formula was soybean meal plus cottonseed cake 50%, corn flour 29%, wheat bran 20%, salt 1%. Each donkey was fed 100g 200g per day at the age of 1 month, 500kg 1000g at the age of 2 months, and 3.5kg after the age of 9 months. 500 kg concentrate was consumed during the whole fattening period. If the cottonseed is fried yellow or cooked until expanded and cracked, each donkey is fed 1 kg a day, the fattening effect is better.
