Dystocia impacts on the fetal viability in local breed goats

Abstract

Background: Dystocia could be described as persistent and troublesome parturition, which proceeds more than 1 hour after laceration of the fetal membranes with recurrently requested assistance. Dystocia perhaps one of two maternal or fetal sources. Aims: The object of this study is to recognize the types of dystocia, and their impact on the viability of goat fetus Materials and methods: A total of 32 local breed goats (22 multipara, 10 primipara), aged between 1-3 years and weight 25-35 kg, suffering dystocia.
Results: The number of multiparous goats was 22 (68.75%), whilst primiparous goats was 10 (31.25%). The multiparous goats have difficult birth with anterior presentation of fetus were 16 (72.75%) and involved 12 (75%) have difficult male birth with anterior presentation, and 4 (25%) have difficult female birth with anterior presentation.
The number of multiparous goats have difficult male birth with posterior presentation of fetus was six (27.25%). Four dead fetuses or births have flexion of hock joints (66.66%), with significant difference toward dead fetus at P< (0.01). Two dead fetuses had flexion of retained hind limbs (33.34%) without significant difference between dead and alive fetus in this type of dystocia.
The number of primiparous goats with difficult births with anterior presentation of fetus was 10 (31.25%). Primiparous goats with difficult male birth with anterior presentation of fetus were eight. Four dead fetuses resulted from ring-womb (50%), four dead fetuses have related oversize (50%) with significant difference between dead and alive fetuses among these types of dystocia at P< (0.01). primiparous goats with difficult female birth with anterior presentation of fetus were 2 dead fetuses (100%) without significant difference between dead and alive fetuses in this type of dystocia.
Conclusions: It can be concluded that dystocia occurred in both multiparous and primiparous goats, and this dystocia due to fetal causes is more than dystocia due to maternal causes. Fetuses associated with cases of dystocia due to fetal causes were dead, whereas more fetuses associated with cases of dystocia due to maternal causes were alive.
