    The process of sexing spermatozoa requires a medium that is able to protect and provide an optimal environment. One of them is extender media that is used to extend the volume of semen. The extender that is commonly used is commercially but some limitation such as price and availability. Therefore, it is necessary to have an alternative extender such as soybean. The aim of this study was to know the quality of sexed sperms diluted using soybean extender. Semen of Bali bull was collected for five times and then subjected to three different extender treatments after sexing; T1 (Soybean), T2 (Tris), T3 (Tris-soybean), and T0 (Fresh semen-tris) was used as control before sexing. The parameters observed were the quality of fresh semen and after sexing. The results of the study showed that the characteristic of Bali bull fresh semen macroscopically in this study was 4.75 mL in volume, cream color, distinctive odor, pH 6.6, moderate consistency, and microscopically motility, viability, abnormality, and concentration were 94.22%, 96.06% 4.89, and 1596├Ś106, respectively. Motility and viability after sexing were significantly (P<0.05) decrease in comparison to the fresh semen (T0) at each treatment both top and bottom layers. In conclusion, the smallest decreased of the sperms motility and viability were still greater than 50%. Different extenders as one of the treatments in the present study did not showing different motility and viability of the sperms. This suggests that the use of tris and soybean or their combination can be used as semen extender for Bali bull sexed semen. Keywords: Soy extender, Bali bull, sexing, motility, viability

    Tujuan penelitian ini adalah untuk mengetahui status metabolit khususnya glukosa, blood urea nitrogen (BUN), dan kreatinin induk sapi Bali pada kebuntingan trimester terakhir. Penelitian ini dilakukan di Kabupaten Bantaeng dengan menggunakan ternak-ternak sapi milik petani-peternak. Sebanyak 21 ekor induk sapi Bali pada periode kebuntingan akhir digunakan pada penelitian ini. Sampel darah dikoleksi dengan interval dua bulan pada semua ternak pada pagi hari melalui vena jugularis ke dalam tabung vakum. Setelah dikoleksi, setetes darah diambil untuk uji glukosa, kemudian sampel disimpan pada suhu 4??C dan kemudian disentrifugasi dalam waktu 4 jam pada 1500 x g selama 15 menit untuk diambil plasma darahnya. Plasma kemudian disimpan pada suhu -20??C sampai dilakukan analisa BUN dan kreatinin. Hasil penelitian menunjukkan bahwa tidak terdapat perbedaan yang nyata (P=0,5944) terhadap konsentrasi glukosa (56,95??18,41 mg/dL vs 53,73??9,32 mg/dL) antara dua bulan interval pengambilan sampel darah. Demikian halnya dengan konsentrasi BUN dan kreatinin tidak menunjukkan perbedaan yang nyata (13,85??4,23 mg/dL vs 11,69 ?? 6,14 mg/dL; P=0,3495), dan (1,61??0,32 mg/dL vs 1,51??0,17 mg/dL; P=0,3920). Dapat disimpulkan bahwa status metabolit induk sapi Bali pada kebuntingan akhir pada penelitian ini masih pada kondisi yang normal

    Soy functions as an extracellular cryoprotectant, which can maintain the integrity of spermatozoa cell membranes with its main content is lecithin. Lecithin from soybeans protects sperm cells from cold stress and reduces the effects of oxidative stress during cryopreservation. This study aimed to analyse the effect of various levels of lecithin diluent on the quality of Bali bull semen during cryopreservation. Semen collection of Bali bull was carried out once a week during four times consecutively using an artificial vagina. The semen was then diluted using the essential ingredient Tris Aminomethan with the addition of powdered soy lecithin; P1 (1 %), P2 (3 %) and P3 (5 %), respectively. Andromed® (K1) as a positive control and Tris without soy lecithin (K2) as a negative control. The parameters observed were motility, progressive motility, kinematics, viability, membrane integrity, and acrosome integrity. The results of this study showed that the dilution of semen with soy lecithin before and after thawing the semen quality was not significantly different (P< 0.05) in motility, viability, plasma membrane integrity, and acrosome integrity. Meanwhile, the kinematics of VAP, VCL, VSL, DAP, DCL, and DSL showed that the average quality increased at P3 compared to K1, K2, P1, and P2, which decreased after thawing or were significantly different (P< 0.05). It can be concluded that Bali bull semen diluted with 3% and 5% of tris soy lecithin produces good characteristics and kinematics, can protect spermatozoa from cold shock

    The objective of this study was to know the incidence of reproductive disorders in smallholder dairy farms. The study was conducted in 12 small dairy farms in Enrekang Regency, Indonesia.  A total of 80 dairy Holstein Friesian cattle consisted of 51 dairy cows and 29 dairy heifers were used in the present study. All dairy cattle at each farm were housed in tie-stall barns.  Reproductive examination was conducted to determine the incidence of reproductive disorders both vaginoscopy and palpation per rectum. The incidence of reproductive disorders was 30.0%; 31.0% in dairy heifers and 29.4% in dairy cows. Uterine infection was the most reproductive disorder suffered to the dairy cattle (12.5%), followed by inactive ovaries and cyst (10% and 5%, respectively). The dairy cattle suffered from reproductive disorders increased the likelihood to mate (artificial insemination; AI) greater than three times as well as to become pregnant. In the population of dairy cattle, 48% AI was conducted greater than three times. The pregnancy rate for the dairy cattle suffered from reproductive disorders was only 20%, with interval from calving to conception was 550 days in average. It can be concluded that high incidence of reproductive disorders in smallholder dairy farms. The occurrence of reproductive disorders decreased the reproductive performance of the dairy cattle in smallholder farms

    The processing of liquid cement is likely to decrease sperm motility. It can be caused by the oxidative reaction to increase the amount of free radicals. Noni (Morinda citrifolia Linn) contains many antioxidants that can serve counteract free radicals. This study aims to determine the addition of extracts of noni (Morinda citrifolia Linn) in order to maintain the individual motility of spermatozoa in the semen liquid Bali cattle. This research was conducted at the Laboratory of Animal Reproduction Semen Processing Unit Faculty of Animal Husbandry Hasanuddin University Makassar. Extracts of noni fruit (Morinda citrifolia Linn) effect on sperm motility (P <0.05). Storage P0 at 3 h to day 2 showed higher motility. Concentration 0,02 gr/ml (P1) gives the best results in maintaining sperm motility on day 3rd to 5th. Extracts of noni fruit (Morinda citrifolia Linn) can retain sperm motility because many contain many antioxidants that serve to neutralize free radicals cause a decrease in sperm motility during equilibration at 5 0C

    Moringa leaves are used as feed to increase the intensity of estrus. It is assumed that the positive effect on the Moringa leaves is due to the presence of vitamin A. This study aims to see the response of vitamin A as a supplement feed to the reproductive performance of beef cows including estrous intensity, number of follicles, follicle diameter, and pregnancy rate. The research was conducted in September-November 2022 in Lappariaja District, Bone Regency, South Sulawesi Province. 10 cows were used which were divided into 2 groups, each group consisting of 5 cows. Group 1 was the control group without vitamin A and group 2 was supplemented with vitamin A. The data on estrus intensity, number of follicles and pregnancy rate obtained were processed using the Chi-square analysis of 2x2 contingency tables. If the Chi-square test does not meet the requirements, the formula used is the Fisher exact test. While the data on the diameter of the follicles were analyzed by ANOVA test. The results of the research data showed that supplementation of vitamin A had a significant difference (P<0.05) on the intensity of estrous. Meanwhile, the results of the chi-square test on the number of follicles and pregnancy rates (P>0.05) showed that there was no significant difference. Likewise, the ANOVA test on follicle diameter between control cows and vitamin A treated cows did not have a significant difference. Although in this study it did not affect the number of follicles, follicle diameter and pregnancy rate. However, it has an economic effect of 20% on the pregnancy rate in the livestock industry scale
