IntroductionThe ovarian follicular dynamics, vaginal electrical resistance (VER), progesterone (P4) and oestrogen (E2) profiles were investigated during the oestrous cycle in four indigenous ewes.Material and MethodsDaily VER values were recorded with a heat detector. The follicles were observed and measured by trans-rectal ultrasonography. Blood was collected daily for hormonal profiles.ResultsA significant variation in VER values (P < 0.05) in oestrus by ewes and position in the sequence of cycles was observed. Trans-rectal ultrasonography of ovaries revealed the presence of 2–4 waves of follicular growth. Study of hormonal profiles by ELISA revealed a positive correlation between E2 concentration and development of follicles and a negative correlation between P4 concentration and their development. The concentrations of oestradiol increased in oestrus and then decreased to a basal level. Follicular growth was accompanied by a rise in the concentration of serum oestradiol. Inversely, when follicles received the stimulation for ovulation, concentration of progesterone started to fall, but after ovulation, it climbed back to its peak and remained at this state until next ovulatory follicle reached its maximum diameter.ConclusionThis study could help to set up a manipulative reproductive technique for improving genetic values in indigenous sheep.

Objective: This study was aimed at clinical evaluation of surgical wound healing in goats treated with ethanolic extract of turmeric (Curcuma longa) rhizomes through topical route. Materials and methods: Eighteen surgical wounds were made in nine goats. The goats were divided into three groups; Group 1 (test group) was treated with ethanolic extract of turmeric, Group 2 (standard group) was treated with Povidone iodine, and the Group 3 was kept as untreated control. Follow up information was recorded from day 0 to day 21 postoperatively. Some morphological characters such as swelling area of wound, elevation of suture line from the skin surface, width of the suture area and contraction length per week were considered to determine the healing process. Bacteriological evaluation was done by conventional bacteriological techniques, and the tissue biopsies were stained by hematoxylin and eosin stains for histopathological studies. Results: Swelling of suturing area (11.51±0.36 mm) and elevation of suture line (2.65±0.41 mm) were lowest in wounds treated with ethanolic extract of turmeric. In histopathological studies, it was seen that tissue debris and hemorrhages disappeared and a thin line of keratin layer reappeared on the epidermal surface of the wound treated with ethanolic extract of turmeric. Conclusion: Ethanol treated turmeric enhances wound healing process in goats. This result could help the veterinarian and the researchers to consider herbal product especially ethanolic extract of turmeric for the treatment and better healing of surgical wounds with minimal complications.

The experiment was carried out to detect the blood serum testosterone concentration after orchiectomy in Black Bengal bucks (Capra hircus). Twelve apparently healthy bucks of 8 - 10 months old were randomly divided into two groups. Group A were castrated surgically through open uncover method and group B remained intact. Local analgesia (2% lidocaine hydrochloride) @ 0.5 mL per spermatic cord and 0.5 mL at the tip of each scrotum were applied initially in all bucks. After aseptic preparation, incision was given at the tip of the scrotum and tunica vaginalis was incised to exteriorize the testis. Anchoring was done at the spermatic cord followed by orchiectomy. The scrotal raphe was incised to reach the other testis and the same procedure was followed. Blood samples were collected from jugular vein before orchiectomy and on day 30. In the castrated bucks, serum testosterone concentration was significantly (P<0.01) decreased from day 0 (6.1 ± 0.2 ng/mL) to day 30 (0.6 ± 0.0 ng/mL), which confirmed the efficacy of castration.Bangl. vet. 2016.
