WH evaluated the data. RK and IY assisted during handling the case. Key words Hydramnios, Anomaly, Buffalo. Hydramnios was successfully managed in a full term pluriparous Nili Ravi buffalo (Bubalus bubalis) that was recumbent and under extreme stress because of intemperate bilateral abdominal distension. Trans- rectal palpation revealed a taut uterus (bulged, tense and inelastic) and alive fetus. Subsequently upon induced cervical dilatation, 60-70 L of amniotic liquid was expelled out and dam delivered completely developed alive male calf with a gross anomaly (presence of a hole in the skull) which could not survive and died soon after the delivery. After the completion of obstetrical case using obstetrical mutation and forced extraction, dam developed the signs of peritonitis, subcutaneous edema and labored breathing. B ovine placental hydropic conditions hydroallantois and hydramnios are estimated to occur in 1 % out of 7500 pregnancies (Jackson, 1995). Hydramnios occurs in 5 to 10 % cases of uterine dropsy. In hydrops of amnion, abdominal enlargement develops slowly over weeks and months (Roberts, 2004). Moreover, the incidence of hydramnios is 9 to 15 times less than hydroallantois (Jackson, 1995; Drost, 2007). Normally, amniotic fuid is secreted by the fetal salivary glands, lungs, skin and associated structures and the volume is regulated through swallowing by the fetus (Zdunczyk and Grunert, 1999). Hydramnios is primarily the result of fetal anomalies, whereas the placenta is normal, and is characterized by the gradual accumulation of amniotic fuid during the last half of pregnancy (Drost, 2007). Excessive accumulation of amniotic fuid can go up to ~25 L (normal volume of amniotic fuid near term is 3-5 L), adverse sequel are rare due to gradual onset and the nature of the disease. Prognosis is fair to good for life and fertility of the dam (Roberts, 2004; Chung et al., 2019). The current case reports an unusual case of hydramnios in a Nili Ravi buffalo (Bubalus bubalis). Case history and clinical examination A full term local pluriparous Nili Ravi buffalo having body condition score 2.5 (1-5), weighing 350 kg presented at Department of Theriogenology, University of * Corresponding author: shahidalivet786@gmail.com 0030-9923/2021/0001-0001 $ 9.00/0 Copyright 2021 Zoological Society of Pakistan Veterinary and Animal Sciences, Lahore, Punjab, Pakistan (31°32′N latitude, 74°20′E longitude). Animal was 6 years old and having 3 rd parity and the last month of gestation (10 month) was completed. In earlier two calving there was normal parturition, without any complication. The owner felt abdominal enlargement, straining and calving like symptoms and call in a local veterinarian. He diagnosed it as twins or fetal hydrops. Due to prolonged straining, the dam was exhausted and ventral recumbent at the time of examination. Vulva was swollen. Bilateral abdominal distension with pear shape abdomen, increased respiration rate 50/min, pulse rate 70/min, loss of body condition 2.5, feeding and drinking was compromised as well. Rectal temperature was subnormal (97°F). Vaginal examination revealed closed cervix. On rectal palpation livability of the fetus was confrmed with speedy movement and plenty of fuids above than normal. Obstetrical procedure and treatment Owner requested for induction of parturition. Before proceeding for the obstetrical procedure, the animal was stabilized by dextrose 10%, D-gluconic acid cyclic 4,5 ester with boric acid calcium salt 1ml/kg and multivitamins. After 1 h, temperature was 97.6°F and cervix was closed. After 2 h, cloprostenol sodium 0.5 mg /kg along with stilboestrol dipropionate 25mg were injected. After 3 h, 1 st ring of cervix started to open and temperature was 98°F. After 5, h 2 nd ring started to open and we injected dextrose 10% at that time. After 7 h, 3 rd ring started to open. On the next day after 19 h, animal was examined and found stable. ABSTRACT Pakistan J. Zool., pp 1-2, 2021. DOI: https://dx.doi.org/10.17582/journal.pjz/20170703140704 Short Communication
