Keywords: Ecotypes. foetus. placentomes. Sahel does. trophoblast.
Morphological characteristics of black/white and brown/white Sahel does' placentas were analyzed. The uterus of twenty (20) pregnant black/white and brown/white Sahelian Does were collected as waste from the Maiduguri Municipal Abattoir. They were then placed in neutral buffered formalin containers containing 10%. Using the crown-rump length (CRL) method of age estimation, the fetuses were separated into three gestational stages. The right uterine horn accounted for 50% and 60% of pregnancies, the twining uterine horns for 30% and 10%, and the left uterine horn for 10% and 40%, respectively. It also showed that in both ecotypes, placenta-maternal contact was loose in the third stage, firm in the second, and fragile in the first. The mean weight, length, and width of the placentomes in each of the three stages varied significantly (P<0.001). The shape of the placentomes such as concave, convex, concave/convex, and flat appearances were found in the black/white ecotype. Whereas concave, convex, and flat appearances were found in the brown/white ecotype. Histologically, the trophoblastic epithelia of both does were found to be made up of syncytia, mononucleated, and binucleated cells with no significant differences in the two ecotypes. In the interplacental spaces, endometrial gland clusters were also observed. The trophoblast epithelia control the chemical exchange between the fetus's and the dam's tissues. These trophoblast epithelia cells are thought to be in charge of producing lactogen and other hormones that keep a pregnancy going until parturition.
