What is fetal maceration?
When a fetus dies in utero, there are changes in the skin and tissues—termed fetal maceration. This process takes place entirely in the womb and stops once the fetus is delivered [10,16]. The phenomenon of maceration was first described in 1922 as loss of the vernix and then skin peeling [20].
What is the difference between mummification and maceration?
This type has been reported in cattle, buffalo, and dogs. Fetal mummification is to be differentiated from fetal maceration, in which the fetus putrefies, in the uterine cavity, in the presence of bacteria and oxygen originating from the open cervix.
What causes mummified fetus in cows?

How long does a fetus decompose?
For the present study, the average time of skeletonization for the bagged foetal remains was 17.5 d and 20.5 d for the foetal remains wrapped in a baby blanket. The surface juveniles show an increased rate of decomposition for the seasons with the greatest relative humidity.
What maceration means?

Bacillus subtilis and Pseudomonas fluorescens are examples of decomposer bacteria. Additions of these bacteria have not been proved to accelerate formation of compost or humus in soil.
What causes fetal maceration in cows?
AMONG farm animal species, fetal maceration has been described most frequently in cows. Incomplete abortion after the third month of gestation is the main reason for a retained fetal bony mass in the uterus of cows ( [Long 2001] [1]).
