The largest males of the group should be selected to be the male reproducers. Those that not<br />

only have the best size, but also those that are best shaped should be selected, preferably from<br />

litters or 3 or more and that have clear colors.<br />

Animals should not be paired with relatives, in other words, parents and children, or among<br />

siblings because this can cause consanguinity problems which causes the following problems:<br />

• High mortality rate among the guinea pigs<br />

• Birth defects<br />

• Lineage degeneration<br />

Consanguinity is avoided by putting reproducers into the nursery every two years.<br />

The reproducers can also be changed with other producers that have quality guinea pigs that are<br />

healthy.<br />

The well-fed guinea pigs reach their reproductive age more quickly. Therefore, if they are well<br />

fed, they can have more young (at 12 weeks old).<br />

There is a larger number of offspring at birth that have a better weight when the female guinea<br />

pigs that are pregnant have been fed well. This in turn improves their multiplying ability.<br />
