ABSTRAK. Penelitian ini bertujuan mengevaluasi tingkat keberhasilan IB semen beku sexing Y. Penelitian menggunakan 39 sapi Peranakan Ongole dan 77 sapi Persilangan Limousin yang di IB secara double dosis. IB menggunakan semen beku spermatozoa Y dengan metode pemisahan Sentrifugasi Gradien Densitas Percoll (SGDP) sapi Limousin yang diproduksi oleh Balai Besar Inseminasi Buatan (BBIB) Singosari. Teknik deposisi semen adalah 4+ yaitu pada posisi cornua uteri selanjutnya dilakukan IB pada jam ke 2 dan ke 8. Untuk akseptor dilakukan penyuntikan BioATP+ dan pemberian pakan konsentrat 3 kg per hari selama 3 hari setelah IB. Variabel penelitian meliputi Non Return Rate (NRR), Service Per Conception (S/C), dan Conception Rate (CR). Hasil penelitian menunjukkan bahwa IB sapi Peranakan Ongole dan sapi Persilangan Limousin yaitu NRR1 sebesar 82,05% dan 89,61%, nilai NRR2 sebesar 76,92% dan 84,42%, nilai CR sebesar 58,97% dan 74,03%, serta nilai S/C sebesar 1,78% dan 1,46%. Kesimpulan penelitian adalah IB menggunakan semen beku hasil sexing Y sapi Limousin pada sapi persilangan Limousin memiliki tingkat keberhasilan yang lebih tinggi dibandingkan sapi Peranakan Ongole. (The success rate of artificial insemination using frozen sexing semen of different breed cow) ABSTRACT. This study aimed to evaluate the success rate of AI frozen semen sexing Y. The material in this study used 39 Filial Ongole and 77 Limousin crossbred cattle in AI in double dose. The spermatozoa used were Y frozen semen of Limousin bull with the Percoll Gradient Density Centrifugation (SGDP) separation method produced by the Singosari Center for Artificial Insemination. The semen deposition technique was 4+, which has the position of the cornua uteri (deep Insemination), then AI implemented with a double dose at the 2nd and 8th hours after estrous. The cow acceptor was injected with BioATP+ and feed by 3 kg concentrate per day for three days after AI. Research variables include Non-Return Rate (NRR), Service Per Conception (S/C), and Conception Rate (CR). The results showed that AI of Peranakan Ongol and Limousin crossbred cattle on NRR1, NRR2, CR values, and S/C values respectively was 82.05% and 89.61%; 76.92% and 84.42%; 58.97% and 74.03%; 1.78% and 1.46%. In conclusion, AI using frozen semen from sexing Y Limousin cattle in Limousin crossbred cows had a higher success rate than Filial Ongole cattle.

(Characteristics of Sexing Spermatozoa Motility in Ongole Cattle with Different Initial Volume) ABSTRACT. Sperm sexing is a technique of sorting a specific type of sperm cell to fertilize the egg cell. One of the sexing methods that can be used for spermatozoa sexing is percoll gradient density centrifugation. This research aims to find out various motility parameters using Computer-assisted Sperm Analysis and the proportion of spermatozoa X and Y using density gradient centrifugation method percoll with different initial volume. The study was conducted at Grati Beef Cattle Research Station, Pasuruan, from January to March 2020. Materials of the study were Semen of 3 Filial Ongole Cattles, aged ± 5 years, with ± 700 kg body weight, mass motility ≥ 2+, and individual motility ≥ 70%. The method used was experimental using a Randomized Group Design with 3 treatment volume when sexing i.e. T0= 1 ml, T1= 1.5 ml dan T2= 2 ml with repetition 11 times. The repetition also functions as groups (blocks). The results showed that after sexing and cooling up to 5oC, the percentage of motility is T0:71.02+10.08 %; T1: 79.63+8,65 % and T2: 83.38+6.67 %. Progressive motility on T0: 47.68+8.71%; T1: 59.61+7.26 % and T2: 62.21+6.74%. Curvilinear Velocity (VCL) on T0: 50.9±7.73 µm/s, T1: 55.2±5.03 µm/s and T2: 53.2±5.97%. Straight-line Velocity (VSL) on T0: 20.8±8.19 µm/s; T1: 21.6±6.02 µm/s; T2: 22.1±5.77 µm/s. The Average Path Velocity (VAP) on T0: 30.2±7.82 µm/s; T1: 32.5±6.14 µm/s and T2 : 31.5±6.18 µm/s. Linearity (LIN) on T0: 40.2±12.26%; T1: 39.1±10.31%;T2: 39.8±7.25%. Straightness (STR) on T0: 67.2±11.20%; T1: 65.7±10.06%; T2: 67.2±7.92%. Wobble (WOB) on T0: 59±9.49%; T1: 58.8±8.63% and T2: 59.1±7.74%. The conclusion of the study is the motility and progressive motility of spermatozoa in samples with an initial volume of 2 ml is better than samples with an initial volume of 1 ml and 1.5 ml.
The success of artificial insemination must be supported by a balance of nutrients for livestock. AI combined with sexing produces offspring according to wishes of the breeder. This study aims to determine the increase in concentration on the success of Artificial Insemination using frozen semen sexing. This research was conducted at the people's beef cattle farm, Sumber Pucung District, Malang Regency. The limousine crosser used was 30 cows. Cattle aged 1.8 – 5 years with BCS 3-5 (score 1-9) Treatment T0 : The usual feed given by farmers (Control). T1: Control+HQFS. Parameters NRR-1, NRR-2, Conception Rate (CR), Pregnancy Rate (PR). The additional feeding of concentrate did not significantly affect the reproductive parameters. The results showed that at T0 the results of NRR-1 and NRR-2 were 80% and 73.33%, respectively. while in T1 it was 73.3% and 66.67%. The results showed that the CR in both treatments was 26% and the results showed that the PR for T0 was 26% and for T1 was 33%. Insufficient feed consumption for all treatments based on NRC requirement data, T0 and T1 dry matter consumption respectively 6.6 and 7.3 Kg/head/day, Protein consumption 0.36 and 0.3 Kg/head/day and TDN consumption of 3.08 and 3.20. kg/head/day.
