ABSTRACT
In the present report, diagnosis and treatment of a case with follicular ovarian cysts in a 5-year-old Persian queen cat is described. In response to palpation of spines, the queen cat presented herself in lordosis and danced up and down with her rear legs. Trans-abdominal ultrasonography examination showed 2 cysts in the left ovary of the queen. Serum estrogen assay indicated elevated level of 17 ß-estradiol concentration [105 pg/ ml]. However, progesterone concentration was normal [0.3 ng/ ml]. Accordingly, the queen was diagnosed with functional follicular cysts. The queen was treated with an administration of hCG intra-muscularly. Thirty [30] days after the administration of hCG, an injection of equine chorionic gonadotropin [eCG] [50 IU] was given intra-muscularly. Natural mating was done with a fertile Persian tom cat. In conclusion, it seems that treatment of functional follicular cysts can be applied to preserve fertility in cats.
ABSTRACT
Anti-Miillerian hormone [AMH] has been observed to decrease with the development of hemorrhagic anovulatory follicles [HAFs] in mares. Two studies were conducted to evaluate AMH concentration in mares with HAFs compared to seasonally anoestrous and cyclic mares, and to elucidate changes of AMH with the development of luteinised unruptured follicles [LUFs]. In study 1, AMH and progesterone were evaluated in seasonally anoestrous, anovulatory [with HAF] and cyclic mares [at mid luteal phase]. In study 2, mares in control and LUF groups were treated with 1500 IU/case hCG when they had a >/=32-mm follicle and an endometrial oedema score of three [day 0]. Mares in the control group received no further treatment. Mares in the LUF group received 1.7 mg/kg flunixin meglumine at the time of hCG administration, and 12, 24 and 36 h after it. Ultrasonography and blood collection for AMH and progesterone measurement were performed on days 0, 1, 2, 4, 6 and 8. In study 1, AMH concentration was lower in seasonally anoestrous and HAF mares than cyclic mares [P<0.05]. Progesterone concentration did not differ between HAF and cyclic mares [P>0.05]. In study 2, AMH was not different between LUF and control mares [P>0.05]; however, progesterone had a lower concentration and a delayed rise after hCG administration in LUF mares compared with the control group [P<0.05]. The results indicated that similar to seasonally anoestrous mares, AMH concentrations decreased in mares with HAFs. LUFs were also found to be functionally different from HAFs

Endometritis is one of the major causes of infertility in mares. The present study was conducted to evaluate intrauterine infusion of Eucalyptus globulus oil as treatment for mares with experimentally induced endometritis. Mares [n=8] were synchronized using two injections of PGF 2alpha [10 mg]14 days apart. All mares were inoculated with a live culture of 5 × 10[6] CFU S. zooepidemicus in the dioestrus phase after the termination of oestrus. The day of inoculation was considered as day 0 of the experiment. On days 3, 6 and 9, cytological and bacteriological specimens were collected to determine endometritis. Mares were randomly assigned to two groups on day 10. Mares in treatment [n=4] and control [n=4] groups received intrauterine 6% Eucalyptus oil solution [100 ml] and intrauterine saline solution [100 ml] for 5 consecutive days. Cytological, bacteriological, and ultrasonographic evaluations were implemented at days 15, 17 and 19 [1, 3 and 5 days after termination of intrauterine treatment, respectively]. The number of mares diagnosed with endometritis, the depth of their intraluminal uterine fluid and the number of infected mares did not change by the treatment [P>0.05]. In conclusion, the 5-day intrauterine infusion of 6% E. globulus oil solution failed to treat experimental endometritis in mares
ABSTRACT
The present study evaluated the effects of diets enriched in saturated and polyunsaturated fatty acids [n-3 and n-6] on reproductive indices, metabolic hormones and metabolites prior to ram introduction in oestrus synchronized ewes. Zel ewes [n=188] were assigned to 4 groups. Ewes in the control group [CON] did not receive fat. Ewes in the 3 other groups received 3% oil/DM/day of palmolein oil [PLM], safflower seed [SAF], or flaxseed [FLX]. Fat supplementation was carried out for 31 days [day 0 = initiation of fat supplementation]. Oestrus was synchronized using CIDR for 14 days starting from day 16 of fat supplementation. Rams were introduced 24 h after CIDR removal. Blood samples were collected on days 0, 30, and 39. There was no difference in oestrus expression and mating parameters among groups. There was no difference in non-esterified fatty acids [NEFAs], insulin and insulin-like growth factor-1 [IGF-1] between day 0 and day 30 among groups. However, changes in cholesterol and LDL concentrations during the same occasions were greater in PLM, SAF, and FLX groups than in CON [P<0.05]. There was no difference in reproductive indices, including: fertility rates, prolificacy and sex ratio of lambs among groups. In conclusion, diets enriched in n-6 and n-3 polyunsaturated fatty acid prior to mating did not affect reproductive performance, insulin, IGF-1 and progesterone in Zel sheep
