Abstract

The aim of this study was to determine the estrus cycle and the length of estrus in Tragulus javanicuson the basis of its vaginal cytology. Vaginal swabs were collected daily at 7 am for two months. Smears ofthe swab were then prepared on glass slide and they were stained with Giemsa. Vaginal epithelial cells;parabasal, intermediet and superficial cells were counted and their percentages during proestrus, estrusand diestrus were determined. Diestrus was characterized by the absent of superficial cells in the vaginalepithel. Proestrus was characterized by the progressive increase in percentage of intermediet/superficialcells in vaginal epithel, whereas estrus was characterized by the presence of superficial/cornification cellsin most vaginal epithel. On the basis of its vaginal cytology, it was determined that the estrous period offemale Tragulus javanicus was 3 days (48-60 h) and the length was 11 days (10-14 day). The change in thecytology of vaginal epithelial cells appeared to a good marker to determine the estrus cycle phase of theTragulus javanicus

Abstract

Ovarian dynamics in the garut ewes had never been studied continuously by using ultrasonography.The aim of this study was to observe development of the follicles and corpus luteums in the estrous cyclein the garut ewes. Garut ewes (n=6) with body weight 30.00±4.05 kg which had normal estrous cycle wereused in this study. All ewes were synchronized by using CIDR-G implantation for 14 days. Ovulation of thedominant follicle, development of the follicle waves and corpus luteum were observed continuously everyday during the estrous cycle after CIDR-G removal. The number of small (2-3 mm in diameter), medium (4-5 mm in diameter) and large (>5 mm in diameter) follicles were aligned during the estrous cycle. Follicleand corpus luteum diameters were measured by using built in caliper in the ultrasound. The resultsshowed 1) the average length of estrous cycle was 19,2±0,8 days; 2) ovarian follicle growth occurred inthree waves during the estrous cycle; 3) the number of preovulatory follicles were 1-2 follicles; 4) theaverage maximum diameters of preovulatory follicle was 7.5±0.5 mm; 5) the average maximum diametersof corpus luteum was 7.3±0.4 mm. In conclusion, the estrous cycle in garut ewes was 18-20 days with 3follicular waves.

Abstract

Determination of estrous cycle especially the length of estrous is an important role in improvingthe fertility and reproductive performance of farm animals. This study was aimed to observe thelength of estrous cycle and estrous period based on cytologic and estrogen (E2) and progesterone (P4)hormone profiles. Samples of vaginal smears were collected daily and stained with Giemsa. Bloodsamples were collected every two days using jugular vein implant catheter. The hormone profileswere analized by radio immuno assay. All data were analyzed descriptively. Results of this studyshowed that there were four lowest points percentage of parabasal epithelial cells with the averageof 14.25%, while the superficial epithelial cells showed four highest points (85.75%). The intervalsbetween lowest point of parabasal epithelial cell and the highest point of superficial cells were at 20,18, and 16 with the average of 18 days. This phenomenon showed a cyclical processed with almostthe same length of time of the actual an estrous cycle pattern in timor deer. The range of E2 concentration was 7.06 to 18.14 pg/ml and P4 concentration was 2.58 to 7.48 ng/ml. The intervaltime between the peak of E2 was 17 days which represented the estrous cycle of timor deer. It isconcluded that analysis of estrous cycle in timor deer can be detected by vaginal cytological andhormone analysis profiles.

Abstract

The objective of this experiment was to examine the fertility of timor deer (Rusa timorensis) frozensemen by artificial insemination (AI) with intracervical technique after estrus synchronization withControlled Internal Drug Release, for Goat (CIDR-G®). Six adult, healthy, and cycling hinds aged 3 to 4years were used in this experiment. The percentage of estrus hind, onset and duration of estrus wereobserved. Pregnancy diagnosis was conducted using ultrasound scanner (USG) at day 120 afterinsemination. The response of estrus was 82.22 %, the onset of estrus was 25.33 hours after CIDR®withdrawal with the length of estrus was 28 hours. The pregnancy rate at first AI trial under sedation was16.7% (1/6), at second and third without sedation was 60% (3/5) and 100% (2/2) respectively. The durationof pregnancy was 248 to 285 days; with the average calving rate was 50%. The result concludes thatinsemination in hind without sedation was better than with sedation.

Abstract

The aim of this study was to compare the efficacy of trehalose and raffinose supplementation in Trisegg yolk (TEY) and Tris soya (TS) diluents in optimizing the quality of Etawah Crossbreed liquid semen.Semen were collected from three sexually mature bucks using artificial vagina. Semen were then evaluatedand divided into six aliquot tubes. Each of them was diluted in TEY and TS supplemented with 50 mMtrehalose or raffinose, respectively. The liquid semen were then stored in refrigerator (5°C). The motility,viability and plasma membrane integrity (PMI) of the spermatozoa were evaluated every 12 hours untilsperm motility remained up to 50%. The results showed that sperm motility in TEY supplemented withtrehalose or raffinose remained up to 50% for 72-84 hours, compared to in TS which was for 48-60 hours(P<0,05). The best diluent was demonstrated by TEY supplemented with trehalose where the spermmotility was 52,82±3,21% up to 84 h compared to raffinose supplementation (52,78±4,41%) and control(51,78±4,86%) which was up to 72 hours, respectively. Meanwhile, the spermatozoa motility in TS diluentsupplemented with raffinose was 52,78±4,41% for up to 60 hours compared to supplemented with trehalose(53,33±3,54%) and control (51,11±4,86%) which was up to 48 hours. In all diluents, the viability ofspermatozoa was 6-9% higher than the percentage of sperm motility, whilst the percentage of PMI wassimilar to the percentage of sperm motility. In conclusion, TEY supplemented with trehalose was the bestdiluents for preservation of Etawah Crossbreed buck liquid semen, and when using TS diluent it isrecommended to add raffinose  rather than trehalose.

Abstract

The objective of this study was to describe the histology and histomorphometry of testis and epididymisof muntjac (Muntiacus muntjak muntjak) during hard antler period. The tissues of the testis and epididymisof an adult male muntjac were processed for histological examination and stained with haematoxylineosine(HE). The parenchyma of muntjac’s testis during hard antler period showed tubuli seminiferi waslined with germinal epithelium: spermatogonia, spermatocyte, spermatid that differentiated intospermatozoa. Sertoli cells were found among the germinal cells. In addition, Leydig cells were foundaround the blood vessel of interstitial tissue along with macrophages. Diameter of the seminiferous tubuleand epithelial thickness were 176,60±7,06 ?m and 50,27±3,62 ?m respectively. The epididymal duct wassubdivided into three segments: caput, corpus and cauda. They were lined predominantly withpseudostratified columnar epithelium which was varied in its thickness. The largest diameter of epididymalduct was found in cauda region (324,26±25,79 ?m), while caput epididymidis had the thickest of epithelialcell (62,21±4,21 ?m) and tended to ce thinner in corpus (49,53±3,01 ?m) and cauda epididymidis(16,30±2,27?m). The density of spermatozoa was observed the most in the lumen of cauda region comparedto caput and corpus epididymidis. In conclusion, the structure of histology and histomorphometry of theseminiferous tubule of testis and epididymal duct of muntjac were similar with small ruminants andother Cervidae during hard antler period.

Abstract

The aim of the research was to study trehalosa supplementation in Beltsville Thawing Solution (BTS) and MIII extender on the quality of frozen boar semen. Semen was collected from nine boars age 5-6 years using glove hand method. The semen were then evaluated macro and microscopically. Semen having >70% sperm motility and >200x106/mL sperm concentration were diluted in two tubes containing BTS and two tubes containing MIII, then kept at room temperature (20-22oC) for 2 hours (holding time). Following this the semen were centrifugated at 2000 RPM for 10 minutes and the supernatant was discarded, the pellet was re-diluted with BTS, BTS-Trehalose 100 mM (BTS-T), MIII, and MIII-Trehalose 100 mM (MIII-T) with 4% glycerol, packed into 5 mL macrotube, equilibrate at 5oC for 2 hours. After equilibration macrotube were frozen horizontally 4 cm above the liquid nitrogen vapor for 20 minutes and then submerged in liquid nitrogen (-196oC) for futher evaluation. After 24 hours the semen than thawed at 52oC for 45 seconds. The results demonstrated that sperm motility in BTS-T (30.00±4.47%) was higher (P<0.05) then MIII-T (26.67±8.16%), BTS (24.17±9.17%), or MIII (21.67±7.53%). This research conclude that suplementation of 100 mM trehalosein BTS extender improved motility of boar sperm after freezing and thawing. ABSTRAK Penelitian ini bertujuan untuk mempelajari penambahan trehalosa dalam pengencer Beltsville Thawing Solution (BTS) dan MIII terhadap kualitas semen beku babi. Semen dikoleksi dari sembilan ekor babi berumur 5-6 tahun menggunakan teknik glove hand method. Semen dievaluasi secara makro dan mikroskopis. Semen yang memiliki spermatozoa motil di atas 70% dengan konsentrasi di atas 200x106/mL dibagi ke dalam empat tabung, dua tabung pertama diencerkan dengan BTS dan dua tabung lainnya dengan MIII. Semen yang telah diencerkan disimpan pada suhu ruangan (20-22oC) selama dua jam (holding time). Semen kemudian disentrifugasi 2000 rpm selama 10 menit. Supernatan dibuang dan pellet diencerkan kembali. Semen yang disentrifugasi dengan BTS, diencerkan dengan BTS gliserol (BTSg) dan BTS gliserol Trehalosa 100 mM (BTSgT) dan yang disentrifugasi dengan MIII diencerkan dengan MIIIg dan MIIIgT. Gliserol yang digunakan adalah 4%. Semen yang telah diencerkan dikemas dalam macrotube (5 mL), diekuilibrasi pada 5oC selama dua jam. Setelah equilibrasi macrotube dibekukan 4 cm di atas permukaan nitrogen cair selama 20 menit dan disimpan dalam container nitrogen cair (-196oC) untuk pengujian lebih lanjut. Setelah penyimpanan 24 jam, terhadap semen beku dilakukan thawing pada suhu 52oC selama 45 detik. Hasil penelitian menunjukkan motilitas spermatozoa dalam BTSgT (30,00±4,47%) paling tinggi (p<0,05) daripada MIIIgT (26,67±8,16%), BTSg (24,17±9,17%), atau MIIIg (21,67±7,53%). Simpulan dari penelitian ini adalah penambahan 100 mM trehalosa dalam pengencer BTSg dapat mempertahankan motilitas spermatozoa babi lebih baik daripada pengencer lainnya.

Abstract

The aim of this study was to determine the optimal mating time in Etawa Crossbred Goat. This studyused 10 ewes, 2-3 years old, with normal estrous cycle. Initiation of estrous using Controlled Internal DrugRelease Implants (CIDR) intra vaginal and released after 12 days. The development of follicles in theovaries wasobserved using transrectal Ultrasonography (USG) every six hours until reach for 66 hoursafter CIDR removal from the vagina. Clinical signs of standing heat and vulva signs were also observedwhile under USG observation. The follicles were divided into three groups based on their diameter:small(<3 mm), medium (4-4.9 mm) and large (>5 mm) which were observed during theestrous phase. Ovulationwas predicted when large follicles (dominant follicles) havenot been seen anymore. The resulta showedthat the average follicles number in ovary after 36 hours CIDR removal were 0-1 (0.8±0.4 mm) small, 0-1(0.9±0.6 mm) medium and 1-2 (1.7±0.8 mm) large, respectively. The large follicles (7-8 mm) wereseen after36 hours CIDR removal or 24 hours after standing heat. Forty two hours after CIDR removal, the largefollicles werenot being seen anymore. It means, the ovulation were predicted in 36-42 hours after CIDRremoval or 24-30 hours after standing heat. The relationship between follicular development and clinical vulva signs (redness, swelling, mucus) revealed that the highest vulva signs (+++) wereseen in 36-42 hoursafter CIDR removal. It was concluded that the ovulation time occurred in 36-42 hours after CIDR removal,with the high intensity of vulva changes. Therefore the optimal mating time in PE 24-36 hours of standingheat or 36-42 hours after CIDR removal.
