The growth and development law of donkey storks is the whole growth stage of the donkey. The younger the age, the faster the growth and development. At different ages, the growth and development of meat donkeys are different. They have the following features: "One year old is tall, two years old is long, three years old is thick". Take the Texas donkey as an example:
The most important feature of the fetal period is that the growth and development intensity of the peripheral bones (ie, limbs) is the largest, and the body height of the newborn quail is equivalent to 65.2% of the mother's body.
During lactation, weaning from birth to 6 months of age, its relative growth strength and absolute growth intensity are the highest in life. The body height energy can complete 51.8% of the whole growth and development after birth, the body length can finish 57.6%, the chest circumference can complete 55.3%, and the tube circumference can complete 58.8%.
Weaning to the 'old' stage is the fastest growing and growth is almost a straight line. One year old accounted for 90.6% of adult height, body length accounted for 86.1% of adulthood, chest circumference accounted for 83.2% of adulthood, tube circumference accounted for 94.3% of adulthood. Therefore, the masses said that "one year is not a donkey, and it is always an embarrassment." This period is the key to nurturing.
The growth rate is still faster between one and three years old. The three-year-old height accounted for 98.7% of adulthood, body length accounted for 96.7% of adulthood, chest circumference accounted for 96.5% of adulthood, and tube circumference accounted for 98.1% of adulthood, indicating the importance of young donkey breeding. Still can not be ignored.
The growth and development of children aged three to five are gradually slow, and they are basically stereotyped after five years of age.
