Ovarian remnant syndrome and uterine stump pyometra in three queens.

Ovarian remnant syndrome (ORS) is the presence of functional ovarian tissue with signs of oestrus as a complication after ovariohysterectomy (OHE) or ovariectomy. Stump pyometra is another complication that can be observed after OHE. However, there are few reports about ORS and stump pyometra in queens. In this report, three queens with recurrent oestrous behaviours after OHE are described. In two queens, ORS with stump pyometra was diagnosed and in one queen ORS alone was diagnosed by physical examination, medical history, vaginal cytology and ultrasonography. Remnant ovarian and uterine tissues were removed by laparotomy. Two queens recovered without any complications; however, one queen died 2 days after surgery. This study reveals that ORS and stump pyometra can result in severe disease and can be fatal.

Effect of the stage of estrous cycle on follicular population, oocyte yield and quality, and biochemical composition of serum and follicular fluid in Anatolian water buffalo

This study was designed to investigate the effects that the different stages of the estrous cycle had on the number of surface ovarian follicles and oocyte yield and quality of Anatolian water buffalo during peak breeding season. Assessments were made on the basis of ovarian morphology, serum and follicular fluid concentrations of variety of biochemical parameters. Following slaughter, blood samples were collected from each animal. The stage of estrous cycle was classified as either the luteal or follicular phase, and surface ovarian follicles were classified as small, medium, or large. The follicular fluid was aspirated, and oocytes were evaluated microscopically for classification into four categories. No statistical differences (p>0.05) were observed regarding the total number of follicles or quality of oocytes relative to the stage of the estrous cycle. Serum high-density lipoprotein cholesterol (HDL), alkaline phosphatase (ALP) and progesterone (P4) concentrations were significantly higher in the luteal phase than in the follicular phase (P<0.05). Significant correlations were observed in the luteal phase between the total number of oocytes and cholesterol (Cho), HDL, sodium (Na), chloride (Cl); A-quality oocytes and Na, Cl, Mg; C-quality oocytes and Cho, HDL, and Mg in follicular fluid. These results offer new information concerning Anatolian water buffalo reproductive physiology, which may be useful for improving oocyte quality in buffalo. This is the first study to describe the number of ovarian follicles, oocyte yield and quality, and a variety of biochemical parameters in the serum and follicular fluid of Anatolian water buffalo during peak breeding season in Turkey.

Postpartum Uterine İnfections in Dairy Cows

Sutcu sigir isletmeleri icin postpartum (PP) donem uterus enfeksiyonlari ekonomik acidan oldukca onemlidir. Ekonomik etki daha cok infertilite kaynaklidir. Infertilite sonucunda hayvanin kesime gonderilmesi, sut uretiminde azalma meydana gelmesi ve buna ek olarak da tedavi masraflari infertiliteyi dolayisiyla uterus enfeksiyonlarini onemli bir ekonomik sorun haline getirmektedir. Uterus enfeksiyonlari PP meydana geldigi donem, semptomun ortaya cikip cikmamasi, turu ve siddetine bagli olarak metritis, subklinik ve klinik endometritis ve pyometra olarak isimlendirilmektedir. Surudeki hayvanlarin neredeyse yarisini etkileyen PP uterus enfeksiyonlarinin hangi tipi olursa olsun, prepartum 3-4 haftalik ve PP 3-4 haftalik surecte meydana gelen metabolik sorunlarin birbiriyle iliskili olarak ve bireyselden cok suru bazinda degerlendirilmesi; ayrica mikroorganizmalarin birbiriyle olan etkilesimleri ve immun yanitin olusum mekanizmasinin hesaba katilarak tedavi girisiminde bulunulmasi daha ekonomik ve kontrollu bir yaklasim olacaktir.

Düvelerde Mastitis: Prevalansı, Risk Faktörleri ve Patogenezi

Dunyada ve ozellikle ulkemizde duve mastitislerinin onemi, yetistiriciler ve veteriner hekimler tarafindan henuz yeterince kavranamamistir. Dogum yapmamis duvelerde meme enfeksiyonlarinin olamayacagi dusuncesinin aksine, alti aylik duvelerde dahi meme ici enfeksiyon sekillenebilmektedir. Gebe duvelerde dogumdan once meme ici enfeksiyon prevalansi %90 oranina kadar cikabilmekte, dogumdan sonra ise bu oran %45 civarinda devam edebilmektedir. Ancak, meme ici enfeksiyon saptanma orani ve bu enfeksiyonlara neden olan patojen tipleri her surude farklilik gosterebilmektedir. Subklinik ve klinik mastitis olgularinda duve meme loblarindan en sik izole edilen mikroorganizmalar Staphylococcus chromogenes, Staphylococcus hyicus, Staphylococcus aureus ve Streptococcus uberis’dir. Ilk gebeligi sirasinda enfekte oldugu belirlenen duvelerde, dogumdan hemen sonra alinan sut orneklerinde ortalama somatik hucre sayisi 20x106 hucre/ml’ye kadar yukselirken, saglikli meme loblarinda bu deger ortalama 3.5x106 hucre/ml olarak belirlenmektedir. Duvelerde mastitise neden olan risk faktorleri arasinda yaz aylarinda dogum yapma, buzagilarin mastitisli sutlerle beslenmesi, buzagilarin birbirini emmesi, duvelerin ineklerle temas halinde olmasi, sinek kontrolunun eksikligi ve barinak kosullarinin sagliksiz olmasi gibi etkenler sayilmaktadir. Bu derlemede yeterince onemsenmeyen duve mastitislerinin prevalansi, mastitise neden olan risk faktorleri ve patogenezinin degerlendirilmesi amaclanmistir.
