At what age do animals attain puberty?
The age at which the maturation process begins in an animal depends on the species. In rhesus monkeys, for example, pubertal changes start around 3 to 5 years of age. Just as in humans, the maturation process can take years, Sisk says.
What is the age of puberty of cattle?
Heifers must reach puberty by 13-14 months of age to calve as two-year-olds. Puberty is influenced by age, weight and breed. Yearling beef heifers conceiving early in their first breeding season, will have increased lifetime production and efficiency.
What is puberty in male animals?
Puberty in male animals is defined by Lincoln [8] as the period when accessory organs and secondary sexual characters develop under the influence of the testes and the animal first becomes fertile. The timing of puberty in male raccoons varies among populations in North America.
Why do different animals reach puberty at a different age?
Male Reproduction
The onset of puberty is affected by breed, genetics, season of birth and nutrition. Ram lambs on a low plane of nutrition may not reach puberty until they are 12 months of age or older. Some breeds reach puberty earlier than other breeds, such as prolific breeds and hair sheep.
Do all animals have an adolescent stage?
Humans are the only animals to go through teenage rebellion, but a few species come close. Adolescence is more than a state of mind. Here's how a few members of the animal kingdom handle the transition to adulthood. By the way, we were literally there when teen-hood was born.
What is the age of puberty?
The average age for girls to begin puberty is 11, while for boys the average age is 12. But it's different for everyone, so don't worry if your child reaches puberty before or after their friends.

How long is a cows estrous cycle?
After puberty, a heifer continues to have regular estrous cycles every 21 days (the normal range is every 18 to 24 days). The estrous cycle in cattle is complex and regulated by several hormones and organs (see Figure 1).
Why is the age at puberty important to beef cattle producers?
Hence, age at which puberty occurs and timing of this event relative to the breeding season will impact the time of conception in the first breeding season, lifetime productivity, and economic efficiency of beef production. ... 3+ years of age) and the time of conception of heifers in their initial breeding season.
Which animal has the longest life expectancy?
1. Bowhead whale: potentially 200+ years old. Bowhead whales (Balaena mysticetus) are the longest living mammals.
Do dogs go through puberty?
The onset of sexual maturity (puberty) is triggered by hormonal changes that lead to physical and behavioral changes. Generally speaking, puppies will start to mature sexually between 7 and 10 months of age. There is some variation and every dog is different.
Is puberty unique to humans?
We humans have quite a lot in common with our primate cousins - opposable thumbs, our use of tools, and the vast majority of our DNA - but one thing we don't share is the long, hellish years of puberty and adolescence. In fact, humans are the only species known to go through the awkward stage of development at all.
How is puberty initiated?
Puberty has begun. The trigger for puberty in both boys and girls is the production of 'gonadotrophin releasing hormone' (GnRH) from a part of the brain called the hypothalamus. This hormone stimulates the pituitary gland to release two hormones, Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH).
How do animals go through puberty?
Puberty is the process we go through to become reproductively functional. ... But for most other animals, the timing of puberty is age-related. Insects and amphibians experience 'metamorphosis', going through two or more distinct stages of their development to move from hatching or birth to adulthood.
How does adolescence start?
Children who are entering adolescence are going through many changes (physical, intellectual, personality and social developmental). Adolescence begins at puberty, which now occurs earlier, on average, than in the past. The end of adolescence is tied to social and emotional factors and can be somewhat ambiguous.
