Pengaruh Pencucian Sperma dengan Lama Waktu Sentrifugasi yang Berbeda Terhadap Kualitas Sperma Kambing Bligon (Effect of Sperm Washing with Different Centrifugation Duration on Sperm Quality of Bligon Buck)
No full textThe objective of the experiment was to examine the effect of sperm washing using SpermRinse with different centrifugation duration (15, 20, and 25 minutes) on the quality of Bligon spermatozoa. Sperm was collected usingartificial vagina from six bucks of 2 (two) year olds. Data were collected for motility, viability, and abnormality of the spermatozoa. Characteristics of the fresh sperm were analyzed based on mean and deviation standard, and followed by Duncan’s New Multiple Range Test (DMRT). The results showed that washing Bligon buck sperm using SpermRinse with different centrifugation times had very significant effect (P≤0.01) on the motility, viability, and abnormality ofspermatozoa. It is concluded that washing Bligon buck sperm using SpermRinse with centrifugation at 1.500 rpm (r = 5.5 cm) could increased sperm quality, of which 20 minutes was the best centrifugation time.(Key word: Bligon Buck, Sperm, SpermRinse, Sperm quality
Stimulasi Laser sebagai Alternatif untuk Induksi Estrus pada Kambing Bligon (Laser Stimulation as an Alternative for Estrus Induction on Bligon Goats)
No full textReproduction is a very important factor in maintaining livestock productivity. For better reproductivity, estrus induction is one of very important ways to be performed. Estrus induction is usually performed with hormonal method,such as application of PGF2α, but the disadvantage is that it is relatively expensive. For this reason, it is necessary to promote technological breakthrough to lower cost of estrus induction. The aim of this study was to know whether laserstimulation on the points of reproductive acupuncture could be performed for estrus induction on Bligon goats, as it is usually performed with hormonal method. Fourteen female Bligon goats aged 2 years old were randomly divided into two groups, each group consisted of 7 goats. Group I was stimulated with laser and group II was injected with 1.25 mg per head of PGF2α. Laser stimulation was conducted for 10 seconds on each point of acupuncture on day 1, 2, and 3, and was repeated on day 11, 12, and 13. PGF2α injection was performed on day 1 and was repeated on day 11. The observed variables were the percentage of estrus, onset of estrus, estrus duration and progesterone level when estrus occurred after the second estrus induction. The results of the study showed that laser stimulation for estrus induction did not indicate significant difference compared to PGF2α injection, in terms of the percentage of goats undergoingestrus, onset of estrus and the estrus duration. It was concluded that laser stimulation could be used for estrus induction on Bligon goats.(Key words: Laser, Estrus induction, Bligon goats

No full textPriyadi DA, Panjono, Bintara S, Hartatik T. 2017. The genotype of Brahman and Brahman Cross Cattle based on SNP in Insulin-Like Growth Factor Binding Protein-3 (IGFBP-3) gene sequences. Biodiversitas 18: 795-800. The IGFBP-3 gene is a potential marker of cattle growth, which is related to the functions that influence the growth, energy metabolism, reproduction and immunity. The genome was isolated from whole blood samples of 10 Brahman cattle and 16 Brahman Cross cattle. Cattle IGFBP-3 gene that targeted in this study was located in the part of intron 2, exon 3 and part of intron 3. The gene targets were amplified using specific primers by Polymerase Chain Reaction (PCR) technique, resulting 563 bp amplification product. As data comparison to reveal the SNP, the GenBank sequences (n = 14) from various breed and countries were used. The objective of this study was to reveal the SNP on the Brahman and Brahman Cross IGFBP-3 gene. The results obtained 3 genotypes from one SNP that spread in the sample population. The SNP was located in intron 2 at position 3,930 (Gïƒ A). The Polymorphism could be recognized by PvuII restriction enzymes. There was not enough evidence to associate the SNP with the phenotype (at pre-weaning age) of Brahman and Brahman Cross cattle. There was a genetic diversity in the population studied. Knowledgeable SNP could be used as genetic markers for further research on Brahman and Brahman Cross cattle.</jats:p

No full textSalah satu permasalahan yang dijumpai di daerah terpencil jika kita ingin melakukan inseminasi buatan pada kambing adalah pembuatan bahan pengencer sperma. Untuk itu perlu diteliti bahan pengencer yang sederhana cara pembuatannya dan bahan yang mudah didapat di lapangan. Tujuan penelitian ini adalah untuk mengevaluasi lama simpan sperma kambing Peranakan Ettawa yang diencerkan dengan susu skim dan air kelapa pada suhu penyimpanan 10οC. Dalam penelitian ini digunakan 5 ekor kambing Peranakan Ettawa jantan dengan umur rata-rata 3 tahun yang memiliki konsentrasi sperma lebih dari 2.000 juta/ml, motilitas lebih dari 70%, dan abnormalitas kurang dari 15%. Penampungan sperma dilakukan menggunakan vagina buatan dengan frekuensi penampungan dua kali seminggu. Sperma hasil penampungan diencerkan menggunakan berbagai level pengencer susu skim dengan air kelapa (P1=20% susu skim + 80% air kelapa; P2=15% susu skim + 85% air kelapa; P3=10% susu skim + 90% air kelapa, P4=5% susu skim + 95% air kelapa; P5=100% air kelapa). Sperma yang telah diencerkan kemudian disimpan pada suhu 10οC dan diuji motilitasnya setiap 24 jam sekali sampai motilitas sperma kurang dari 30%. Hasil penelitian menunjukkan bahwa level pengencer susu skim dengan air kelapa berpengaruh (P<0,05) terhadap lama simpan sperma. Bahan pengencer P2 mempunyai lama simpan yang paling lama (3,4±0,55 hari) dibandingkan dengan P1 (2,6±0,55 hari), P3 (2,6±0,55 hari), P4 (2,4±0,55 hari), dan P5 (2,2±0,45 hari)

The Effect of Thawing Duration on the Post Thawing Quality of Bali Cattle’s Frozen Semen and Conseption Rate in Smallholder Farms of East Lombok Regency
No full textThis research aimed to identify the effect of the length of thawing time on the quality of Bali cattle postthaw semen and to investigate the resulting pregnancy rate. This research was conducted at Wanasaba Village, specifically Tanaq Mira Village, Wanasaba District, East Lombok Regency. Five samples of Bali cattle semen were collected for insemination from each of three different farmer groups. The semen sample from the remaining frozen semen inseminated by the inseminator was used in this research. Tanaq Mira Village's inseminator performed thawing during the trip from the artificial insemination (AI) station to the farmer group's location. This research observed the microscopic quality of the postthaw frozen semen covering motility, viability, and abnormality. Moreover, the pregnancy rate on AI acceptors using the non return rate (NRR) parameter or the number of female parents who returned to estrus after being inseminated were observed. The observation was conducted on three farmer groups with different distances and lengths of thawing time. Each farmer group was observed five times. The collected data were then analysed by using one-way analysis of variance(ANOVA). The research indicated that the distance of the farmer group’s location significantly affected (P0,05) the sperm abnormalities. The Sapeng farmer group had the highest NRR, as much as 80%. According to the NRR score, it can be concluded that the thawing process using the thermos within less than 10 minutes resulted in the best yield
