How to Tell Your Guinea Pig Sex?
It is quite simple, against information, we usually find! You can even tell the sex of a few days old little piggy. When the piglet reaches the age of about two weeks, sex determination shouldn’t cause any problems. You just need to know, what things you should pay attention to.
Two Weeks Old Guinea Pig
In the pictures bellow reproductive organs of two weeks old piggies are described (of the girl and the boy).
One Month Guinea Pig
There are not many differences between one month old pigs sex organs and two week old ones, although they are bigger.
The girl’s proportion of hollows is changing a bit – the vertical line of the letter “Y” is much shorter. Only diagonal lines are clearly visible.
The boy’s penis is much better visible.
Three-Months Old Guinea Pig
Reproductive organs of three months old individuals are already fully developed.
There is no difference comparing to the one month old piggy.
You can see well-developed testicles.
After The Birth
A piggy is born with fur and it is a size of a mandarin. The moment after it is licked by its mother, little piggy starts to look around. A few hours after the birth, she starts going out of the house and touring the cage.
Little pigs have disproportionately big paws and head compared to the rest of their body. With time, however, body proportion will change to the benefit of the backside.
A Few First Days
Little pigs are very brave and curious about the world. After a few days they start eating solid food, although they still drink milk from their momfor anotherthreeweeks. Their walk is clumsy and sometimes they fall down.
The First Month
About 3-4 week old pigs should stop drinking mother’s milk. They are already quite big. They reach the size of over half the length of the mother’s body.
They love to play and chase each other. They jump funny and they wave their little heads. Males start to show an interest in females at the age of three weeks, although the females don’t want to play this type of games.
When a pig reaches the age of one month, it is a perfect moment to give it away to new owner, if we don’t want to keep it.
Between the First and The Third Month
Females achieve sexual maturity in the second month of their life, and males in the third month (officially). However, it can happen that our little piggy will be ready for breeding at the age of one month. That’s why you should separate males from mother and sisters, when males reach age of one month. Around the second month little pigs start calming down. They become less energetic. They sit and lie more than jump and run around the cage. If we want to sterilize males, we must wait until they reach the age of three months. Only then they are big enough and have well developed testicles. The vet won’t do this earlier anyway.
After the Third Month
Pigs have already reached sexual maturity; still grow, but very slowly. A pig can grow until it’s six months old.
Species: Cavia porcellus (guinea pig)
Body length: 23 – 35 cm (females are usually shorter),
Weight: 700 – 1300 grams,
Life expectancy: 7 – 12 years,
Number of young per litter: 1 – 6 (usually 2 -3),
Body temperature: 37-39 Celsius degrees.
We don’t recommend breeding guinea pigs. There are usually no problems during pregnancy and delivery, but bringing the younger generation up may be troublesome.
If you get a pig with a “surprise”….you must know some facts. Below we are presenting some information for future “parents”.
Pregnancy lasts 8-10 weeks and it is notvisible until the end of the fifth week. The pregnancy can be dangerous, if the pig is over a year old and it is its first pregnancy. Bones of a pelvis cannot spread enough – in this age they are firmly joined (if the piggy didn’t give a birth before). In this case you should go to a vet. Only a doctor can help.
How to Tell Your Guinea Pig is Pregnant?
If you have doubts, whether you are dealing with pregnancy, or perhaps your pig simply grew fat, at first you can check its belly. If it’s a fat issue, guinea pigs tummy will be soft in touch. If piggy is pregnant, its belly will seem to be “stuffed” and strained – you may feel like touching a balloon. Moreover during the pregnancy piggy’s sides also grow. During three last weeks you may see babies moving and even hear them. Of course, if you want to be sure, go to a vet to do the ultrasound scan.
Before the Birth
Three to four weeks preceding the delivery, the expectant mother should be separated from other pigs. During last weeks you shouldn’t take the guinea pig out from the cage, in order not to harm babies. You can pat her. During pregnancy you should feed your piggy normally, although you can give her a little bit more food(even overfeed her). The piggy will demand more food.
Birth and After The Birth
Labor is very quick (usually a few minutes), mainly at night. The pig won’t show any signs of an upcoming delivery. There won’t be a big mess after, guinea pig as every rodent, eats the placenta. After the birth, little pigs should spend time only with their mother. They should not be taken out of the cage, till they are two weeks old. The mother can reject them, if someone else’s smell is on them. Smell of her owner on her children doesn’t disturb her very much. The pig looks after her children, she feeds and licks them. However, she isn’t too possessive and isn’t much upset, when one of her babies is missing for a moment.
