Habitat Of The Brazilian Guinea Pig
The Brazilian Guinea Pig lives in the neotropical region, with the exception of tropical rain forests. The rodents inhabit savannahs and grasslands at altitudes anywhere between four hundred and three thousand (400-3000) m above sea level. However, they can also be found in the highlands of the Andes mountain range. They prefer dense ground vegetation in which they create a complex series of pathways.
Diet Of The Brazilian Guinea Pig
Brazilian Guinea Pigs are herbivores who predominantly feed on true grasses (Poaceae) but will eat other grass. They eat leaves, stems, seeds, nuts, grains and sometimes tubers or roots.
Behaviour Of The Brazilian Guinea Pig
The Brazilian guinea Pig is a social creature, who tends to live in small familial groups, made up of one male, one to two (1-2) females and their offsprings. Several dozen groups of the Brazilian Guinea Pig are able to live in adjacent territories. The rodents graze in small groups so they can detect potential predators easily. They communicate by auditory signals, screams and squeals and scent marks.
Interesting Tip
- The male Brazilian Guinean Pig may not mark their territories but will mark their mates.
- They have two distinct scent glands, a sebaceous gland located on their dorsal part of their bodies and the perineal gland, located near the anus.
Reproduction Of The Brazilian Guinea Pig
These rodents are polygynous meaning that one male can mate with a number of other females, typically not more than two (2). Breeding occurs all year round and a female can produce as much as five (5) litters per year. The Brazilian Guinea Pigs can reproduce at twenty-eight (28)days old. Brazilian Guinea Pigs have a gestation period of sixty-two (62) days after which the female gives birth to about two (2) pup per litter. At birth, the Brazilian Guinea Pigs’ eyes are open and their bodies are completely covered in fur, able to move simply hours after. They are weaned at about twenty-five days old but they are able to eat solid food at three (3) days old. Soon after maturing, the juveniles move on.
