Abstract

PO cattle have weaknesses to show clear estrus signs which cause difficulty in artificial insemination implementation. The present study was designed to obtain ovarian dynamic as effect of GnRH injection in ovsynch protocol based on progesterone intravaginal device. Heifers (18) and cows (n= 12) were allocated to one of three groups. Cuemate-PGF2? (CP) group inserted with a Cuemate on day 0-7 and injected with prostaglandin on day 7. Cuemate-PGF2?-GnRH (CPG) group was treated as CP group with the addition of GnRH injection on day 9. GnRH-Cuemate-PGF2?-GnRH (GCPG) group was treated as CPG group with addition of GnRH injection on day 0. Ultrasonography was performed on days 0-3, day 7 until ovulation and 7 days after ovulation. Percentage of ovulation synchronization increased significantly (P<0.01) between CP, CPG, and GCPG, respectively, both in heifers (16%, 50%, and 85%, respectively) and cows (0%, 60%, and 100%, respectively), on day 11. Preovulatory follicle diameters between CP, CPG, and GCPG treatments were not different significantly both in heifers (11.9±0.5, 11.9±0.5, and 12.1±0.6 mm, respectively) and cows (11.7±0.4, 11.8±0.7, and 11.1±0.6 mm, respectively). This study concluded that GCPG protocol increased the synchrony of ovulation rate both in cows and heifers, without affecting the follicle preovulatory and CL diameters.Key words: ovarian dynamic, GnRH, ovsych, PO Cattle

Abstract

The aim of this study was to describe the sonographic appearance of abdominal wall at the left flank of laparotomy incision site in 11 mated Ettawah grade does. Brightness-mode ultrasound examination by using transducer with frequency of 5.0-6.0 MHz was conducted to grouping the does based on their pregnancy statuses. The incision site of the abdominal wall at left flank laparotomy was transcutaneous-scanned as long as 8 cm vertically. The sonographic appearance of the laparotomy wall thickness showed that in all groups of does were similar and not different statistically. The thickness of oblique external and oblique internal abdominal muscles increased in the pregnant does as compared to non-pregnant does (P<0.05).Key words: laparotomy, left flank, ultrasonography, incision site, Ettawah grade does

Abstract

Rectovaginal fistula (RVF) merupakan fistula yang terbentuk antara rektum dan vagina sehingga feses masuk ke vagina dan menyebabkan endometritis. Seekor kuda primipara umur 6 tahun mengalami RVF. Rehabilitasi RVF pada kuda ini dilakukan dengan tindakan bedah penjahitan fistula dengan anestesi general. Sedasi menggunakan xylazine, induksi dengan ketamine serta maintenance dengan inhalasi isofluran. Luka baru dibuat pada tepi fistula dan penjahitan dilakukan sesuai dengan arah fistula dengan jahitan sederhana. Terapi pascabedah yaitu pemberian antibiotik selama 10 hari, antiinflamasi 5 hari dan analgesik 3 hari. Diet pascabedah dilakukan dengan memberikan pakan rumput segar. Persembuhan jaringan 10 hari pascabedah ditandai dengan terbentuk jaringan baru dan tidak ada feses yang masuk ke dalam vagina.

Abstract

Granulosa Theca Cells Tumor (GTCT) is the most common equine ovarian tumor that frequently occured in mare with indication of stallion like behaviour and nymphomania. A mare with stallion like behavior was diagnosed with ultrasound has GTCT with diameter of 147 mm of the left ovary and hypofunction of the right ovary. The GTCT was removed by midline laparotomy. Anesthesia was performed by using Xylazin and Ketamine and maintenance with Isoflurane. Large size of GTCT could be safely removed by abdominal midline surgery for extraction of tumor.
