Thanks Pigpal, I see that it is referred to as well in Richardson regarding guinea pigs (thanks Rosalee).
Clinical signs: This may occur before pregnancy is detected and therefore go unnoticed, it just being assumed that the sow is taking her time in conceiving, or that she is infertile. Any stress such as a sudden diet change may lead to resorption, as will a period of poor feeding. Sows with severe mange mite infestation are likely either to resorb or abort their litters. If foetal loss occurs in the very early stages of gestation the sow may not outwardly appear sick.
Treatment: Avoidance of sudden stress and provision of an adequate diet should prevent the occurrence of resorption.
So, my next question would be, who, other than a very good breeder who is monitoring the cavy in a breeding program, would be able to diagnose resorption? Would not the average person simply assume the guinea pig is not, after all, pregnant?
Richardson goes on to talk about miscarriage and abortion, which occurs when the foetuses have reached a later stage in their development.
Richardson also says that abortion and resorption can occur as a consequence of a systemic infection and been associated with Bordetella bronchiseptica
, Streptococcus pneumoniae
Yes, I wanted to be very clear on my facts before I respond. If I stretch the word bounce to ´lightly bounce a finger off the abdomen,´ maybe I could stretch bounce into palpate, but somehow, I doubt that´s it.
