Abstract
Penelitian ini bertujuan untuk mengkaji karakteristik pemeliharaan sapi, menganalisis pengaruh penambahan pakan, biokimia darah, endoparasit serta kondisi fisiologis sapi terhadap keberhasilan IB pada sapi persilangan Limousin di peternakan rakyat. Penelitian ini dilakukan tiga tahap yaitu pertama, survey karakteristik reproduksi dari 100 ekor peternak; kedua, penelitian pengaruh suplementasi pakan terhadap keberhasilan kebuntingan 30 ekor yang terbagi menjadi dua perlakuan (P0 tanpa perlakuan pakan; sedangkan P1 dengan suplementasi pakan 1 kg/ ekor/ hari selama 14 hari sebelum IB, dan 7 hari sesudah IB) masing-masing 15 ekor sapi; ketiga evaluasi keberhasilan kebuntingan terkait Non Return Rate1 (NRR1) dan NRR2, conception rate (CR), pregnancy rate (PR), kadar biokimia darah, tampilan organ reproduksi dan endoparasit. Data ditabulasi dengan Microsoft Excel 2019, yang selanjutnya dianalisis dengan software IBM SPSS statistics 26 dengan uji T. Hasil analisis statistik konsumsi nilai gizi pakan BK, PK, SK dan TDN berbeda nyata dari kedua perlakuan (p<0,05). Hasil IB sapi persilangan Limousin (P0) memiliki NRR1, NRR2, CR, dan PR<P1. Kadar kolesterol sapi P0 bunting> sapi P1 yang mengalami gangguan reproduksi (gangrep). Kadar total protein darah sapi bunting>sapi gangrep. Sapi yang mengalami gangrep memiliki kadar glukosa <sapi bunting. Sapi BCS 5-6 (skala 1-9) tingkat kejadian gangrep tertinggi berkisar 20-60%, tingkat keberhasilan kebuntingan tertinggi terjadi pada BCS 6-8 berkisar 20-60%. Hasil analisis jumlah telur cacing, sapi yang terinfeksi ringan tetap dapat bunting 13,33%, terinfeksi sedang tetap dapat bunting 36,67%, dan terinfeksi berat mengalami gangrep 23,33%. Disimpulkan bahwa karakteristik reproduksi sapi persilangan Limousin di peternakan rakyat memiliki S/C 2,91±0,11; days open 116,93±2,31 hari dan calving interval 13,67±0,08 bulan. Penambahan pakan tidak berpengaruh terhadap keberhasilan IB dan status nutrisi sapi persilangan Limousin, kemungkinan diakibatkan tingginya kasus gangguan reproduksi, faktor neurotransmitter dan kecukupan nilai gizi pakan.
English Abstract
This research aims to examine the characteristics of cattle rearing, analyze the effect of additional feed, blood biochemistry, endoparasites and the physiological condition of cows on the success of Artificial Insemination (AI) in Limousin cross cows in smallholder farming. This research was carried out in three stages, namely first, surveying the reproductive characteristics of 100 respondent farmers; second, research on the effect of feed supplementation on pregnancy success of 30 cows divided into two treatments (P0 without feed treatment; while P1 with feed supplementation of 1 kg/head/day for 14 days before AI, and 7 days after AI) each with 15 heads cows; the third evaluation of pregnancy success is related to Non Return Rate1 (NRR1) and NRR2, conception rate (CR), pregnancy rate (PR), blood biochemical levels, appearance of reproductive organs and endoparasites. Data was tabulated using Microsoft Excel 2019, which was then analyzed using IBM SPSS statistics 26 software with the T test. The results of statistical analysis of the nutritional value of dray matter (DM), crude protein (CP), crude fiber (CF) and total digestible nutrient (TDN) feed consumption were significantly different from the two treatments (p<0.05). The AI results of Limousin cross cows (P0) have NRR1, NRR2, CR, and PR<P1. Cholesterol levels of pregnant P0 cows>P1 cows experiencing reproductive disorders. Total blood protein levels of pregnant cows> reproductive disorders cows. Cows experiencing reproductive disorders have glucose levels <pregnant cows. For BCS 5-6 cows (scale 1-9), the highest incidence of reproductive disorders is around 20-60%, the highest pregnancy success rate occurs in BCS 6-8, around 20-60%. The results of the analysis of the number of worm eggs showed that 13.33% of mildly infected cows remained pregnant, 36.67% of moderately infected cows remained pregnant, and 23.33% of heavily infected cows experienced reproductive disorders. It was concluded that the reproductive characteristics of Limousin cross cows on smallholder farms had an S/C of 2.91 ± 0.11; days open 116.93 ± 2.31 days and calving interval 13.67 ± 0.08 months. The addition of feed did not affect the success of AI and the nutritional status of Limousin cross cows, possibly due to the high number of cases of reproductive disorders, neurotransmitter factors and the adequacy of the nutritional value of the feed.
