The objective was to evaluate ovarian activity reversibility in domestic queens after short-term contraceptive treatment with deslorelin acetate. Ten mature were used. In all queens, the estrous cycle evaluated every 72 h by vaginal cytology (VC) and behavior assessments. When had VC characteristic of interestrus or diestrus, one acetate implant (4.7 mg) placed subcutaneous tissue interscapular region (day insertion = Day 0). Thereafter, performed 48 on 90, implants removed. At 100, estrus...
Summary Temporary meiosis arrest with cyclin-dependent kinases inhibitors has been proposed in order to improve the quality of vitro matured oocytes. In sheep, however, this phenomenon rarely investigated. Therefore, present study aimed evaluate effect different incubation times roscovitine on nuclear maturation and cumulus cell expansion sheep cumulus–oocyte complexes (COCs). For this, COCs were cultured for 0, 6, 12 or 20 h basic medium (Control) containing 75 μM (Rosco). After, they (IVM)...
Objectives Owing to the lack of literature on training cats use an artificial vagina (AV), we performed a retrospective study success tom for semen collection using AV. Methods Records from 20 (2009 until 2019) AVs were analyzed. Sexual preferences, behavior towards humans, queens and other cats, as well libido, number sessions rate observed. Data are presented percentages results described subjectively. Results In 85% AV was successfully. Training unsuccessful when libido low or absent....
Freeze-drying sperm seems to be the ultimate alternative preserve cells from endangered species because of its easiness in transportation and storage samples. This technique has already been used for equine, bovine, murine, rabbit, canine, feline cells. However, it is still important verify DNA integrity such samples produce viable offspring. The objective this study was reliability acridine orange (AO) staining assess damage freeze-dried Three normospermic cats were as donors, collected...
Objectives The present study investigated the effect of contraceptive treatment with deslorelin acetate on in vitro embryo production and oocyte recovery domestic queens. Methods Twenty-one mature cats were used. Eleven queens (treated group) one tom kept an experimental cattery, 10 privately owned (control group). When interestrus or diestrus (day 0) a implant (Suprelorin, 4.7 mg/animal) was inserted into subcutaneous tissue interscapular region all treated group. After 6 months treatment,...

The aim of this study was to evaluate re-expansion and ultrastructure in vivo-produced canine embryos immediately after collection (Co; n = 6) 24 h vitro culture (Co24; 6). For embryo collection, two bitches pro-oestrous were monitored every 48 by vaginal cytology up the detection 80 90% superficial cells. Then, they inseminated 3 times on alternate days with fresh semen from 1 fertile male. Embryo collections performed ovariohysterectomies uterine flushing 12 first artificial insemination....
The objective of this study was to evaluate the security and analgesia anesthetics protocols usually used for electroejaculation (EEJ) in domestic cats. Fourteen toms were anesthetized with 4 submitted a 3 series electric stimuli (2-6 mA). heart rate, respiratory temperature, pain sensibility eyes blink analyzed prior after induction, during electroejaculation. anesthesia protocol that isoflurane best analgesic parameters, speed recuperation catsKEYWORDS: Electroejacutation; cat; anesthesia.
