INTISARITujuan penelitian ini adalah untuk menentukan grade dan koefisien reproduksi sapi Bali betina bibit di NTB. Penelitian dilakukan di Kabupaten Lombok Barat mewakili Pulau Lombok dan Kabupaten Dompu mewakili Pulau Sumbawa. Untuk menentukan grade sapi dilakukan pengukuran terhadap berat badan, panjang badan, tinggi gumba, lingkar dada, dan pengamatan eksterior, kemudian data dianalisis dengan alat bantu statistik deskriptif. Untuk mengetahui koefisien teknis reproduksi dilakukan wawancara kepada para peternak dan selanjutnya data dianalisis secara deskriptif dengan bantuan tabel. Hasil penelitian menunjukkan bahwa: dengan kriteria Ditjen Peternakan 2006, berdasarkan tinggi gumba (TG), grade sapi Bali betina bibit di NTB dapat diklasifikasi menjadi, grade I = 36,5%; II = 49%; III = 7,5%; dan tidak masuk grade (TMG) = 7%; berdasarkan panjang badan (PB): grade I = 38,5%; II = 46%; III = 7,5%; dan TMG = 8%. Apabila diklasifikasi berdasarkan wilayah pulau, nampak bahwa grade sapi Bali betina bibit di Pulau Sumbawa lebih baik dari pada di Pulau Lombok. Grade sapi bibit di Pulau Lombok berdasarkan TG: grade I = 19,8%; II = 62%; III = 11%; dan TMG = 7%; berdasarkan PB: grade I = 18,8%; II = 61%; III = 10%; dan TMG = 9%. Grade sapi bibit di Pulau Sumbawa berdasarkan TG: grade I = 57%; II = 34%; III = 3%; dan TMG = 7%; berdasarkan PB: I = 61%; II = 29%; III = 4%; dan TMG = 6%. Dari sisi koefisien teknis reproduksi, jarak beranak dan umur pedet disapih masih cukup panjang, yaitu masing-masing sekitar 15 bulan dan 6 bulan.(Kata kunci: Grade sapi, Koefisien reproduksi, Sapi Bali betina bibit) ABSTRACT

The objective of this research was to study the importance of economic traits on Bali cattle in Mataram city. This research was analytical descriptive that was carried out by using the survey method on 39 respondents and direct measurement of shoulder height, body length and heart girth on 72 calves. The results showed that age at first calving was 32,81 ± 3,40 months, and calving interval was 11,10 ± 1,04 bulan. The percentage of calves born in population was 46,19%, natural increase accounted for 38,47 %, weaning age was 6,63 ± 0,55, service preconception showed the value of 2,11 ± 1,05, sex ratio was 52,78 for male and 47,22 for female, first estrus was 19,29 ± 2,41 months. The estimate number of supply was 12,11% for heifer and 12,11% for bullock.

A descriptive study using 30 female local Lombok ducks age ready to lay was carried out to know the local Lombok egg duck production and its quality raised intensively in Centre Lombok for making a salted egg. The observation was done in three months. Variable observed were eggs production (monthly production, egg weight, egg index), shell quality (texture, thickness, color), and internal egg quality (yolk index, yolk color, yolk and albumen weight ratio, egg spot). Data were analyzed by using simple statistic to get the mean and the deviation standard. The observation results were: monthly egg production in the first three months were 58,15 ± 10,98%; 60,25 ± 10,60%; 50,00 ± 15,73%; average egg weight and its index were 61,42 ± 2,73 gram and 0,74 ± 0,10. The shell surface was smooth and the thickness was 0,40 ± 0,09 mm. The shell color was greenish dark blue. The yolk index was 0,47, the yolk color varied between 10 and 14, the yolk albumen ratio was 1.04, and there was not an egg spot. The quality of the local Lombok egg ducks was good for making a salted egg.

A potential production study of Sasak duck and the non-indigenous ducks (Campbell, mojosari, MA, and alabio ducks) was carried out in Centre Lombok Regency. Research materials were 50 female DODs for each breed. The variables observed were growth rate and feed conversion. The growth rate was measured every week from started from DOD until 10 weeks old. The data obtained were analyzed by using one-way ANOVA Complete Randomized Design. Results of research: body weight gain (BWG) for all breed increased until age between 5-6 weeks after that declined. Sasak and Campbell BWG were the least. The shank length average of all breed increased 253,86% within ten weeks. The shank length gain (SLG) for all breeds decreased steadily from the first week. The relative SLG of Sasak and MA ducks were between labia duck and Campbell ducks. The relative SLG of labor duck was highest and while that of mojosari ducks was the lowest. The average of the shank diameter gain within 10 weeks for all breeds increased 217.43%. There was no shank diameter difference (P 0.05 >) between Sasak ducks and the nation Lombok indigenous ducks. The average of middle finger length (MFL) of all breeds from one to 10 weeks increased 181,90%. The relative MFL gain of Sasak and Campbell ducks were less (P < 0.05) than that of the other three breeds. The feed conversion of Sasak, Campbell ducks, mojosari, MA, and alabio were 3.60; 3.90; 4.04; 4.06, and 3.66 consecutively.

This study aimed to identify the diversity of qualitative and morphometric traits of Kampung chickens based on the comb-types in Lombok Island. Four hundred and seventeen Kampung chickens that are maintained traditionally were used in this study. The method used was a survey. The determination of location was done by purposive sampling, and samples taken were selected by random sampling. Qualitative data included comb-type, fur color, skin color, and foot color. Morphometric data included comb height, shank length, tibia length, femur length, the distance between pubic bones, the distance between the pubic bone and breastbone and body weight. Data were analyzed using simple statistical analysis. The results show that there were 4 (four) types of comb namely walnut comb (36.45 percent), single (30.45 percent), pea (24.46 percent) and rose (8.64 percent). Fur colors found were black, golden, striated and white. White fur color was only found in pea combs. The earlobe colors were red and white. Shank colors were black, white and yellow. The skin colors were yellow and white. The highest morphometrics of Kampung chicken was found in chickens with the type of rose comb which showed comb height of 12.16 + 2.78mm, shank length of 74.26 + 11.62mm, tibia length of 88.47 + 11.87mm, femur length of 82.11 + 12.45mm, distance of two pubic bones of  35.95 + 7.32mm), distance between the pubic bone and breastbone of 54.74 + 9.86mm and body weight of 1658.19 + 339.63gram.
