AbstrakPenelitian bertujuan untuk mengetahui performa domba lokal jantan yang diberi ransum limbah tongkol jagung olahan. Penelitian menggunakan metode eksperimental dengan rancangan acak lengkap (RAL). Data yang terkumpul dilakukan analisis sidik ragam, kemudian dilanjutkan dengan uji Jarak Berganda Duncan. Dua puluh ekor domba lokal jantan dialokasikan ke dalam empat ransum percobaan yaitu, = 60% rumput segar + 40% konsentrat = 30% tongkol jagung giling + 30 % rumput segar + 40% konsentrat = 60% tongkol jagung giling + 40% konsentrat = 30% tongkol jagung giling olahan + 30 % rumput segar + 40% konsentrat = 60% tongkol jagung giling olahan + 40% konsentrat. Tongkol jagung olahan diperoleh dari hasil perendaman dengan filtrat abu sekam pada (FASP) 20% selama 3 jam. Domba yang diberi ransum percobaan menghasilkan pada konsumsi bahan kering harian, PBBH, dan pertambahan lingkar dada, namun tidak terhadap pertamabahan tinggi pundak, pertambahan panjang badan yang bebeda nyata (P<0,05), pertamabahan lingkar pinggang, konversi ransum, dan feed cost per gain. Ransum percobaan yang mengandung 30% tongkol jagung olahan menghasilkan PBBH dan lingkar dada yang paling tinggi (P<0,05) yaitu 84,41 g/hari dan 11,19 cm. Kesimpulan hasil penelitian ini adalah penggunaan tongkol jagung olahan pada ransum sebanyak 30% menghasilkan performa yang terbaik.

Completely randomized design was used as an experimental method in this research. Collected data ewre analyzed using analysis of variance followed by Duncan multiple range test. Twenty local rams allocated in to four diet treatments, they were R 0 = 60% fresh grass + 40% concentrate, R 1 = 30% grinded corncob + 30% fresh grass + 40% concentrate, R 2 = 60% grinded corncob + 40% concentrate, R 3 = 30% treated grinded corncob + 30% fresh grass + 40% concentrate, R 4 = 60% treated grinded corncob + 40% concentrate. Corncob was hydolized by rice husk ash filtrate 20% during 3 hours. Treated diets have a significant effect (P<0.05) on feed intake, average daily growth and chest hoop but no significant (P>0.05) on shoulder height, body height, waist hoop, feed conversion and feed cost per gain. Lambs fed diets containing 30% treated corncob showed the highest (P<0.05) daily growth gain (84.41 g/day) and chest hoop (11.19 cm). In conclusion, the utilization of treated corncob in 30% of the diet produced the best performance.

The development of local genetic resources is important to meet the need of high demand of lamb meat in Indonesia, especially in West Java, through the selection of superior breeds of Garut sheep. The selection has to be initiated by studying the Garut sheep performances to determine the environmental factors affecting the preweaning performances of the sheep and involving those factors in the analysis of genetic parameters. The study was held on the Unit Pelayanan Teknis Dasar Balai Pengembangan Perbibitan Ternak Domba dan Kambing (UPTD-BPPTDK) Margawati Garut from August 21st to September 18th, 2019. The purpose of this experiment was to study the effect of sex and litter size on preweaning weight, i.e birth weight, weight on 30, 60, 90 days, and weaning weight (100 days). The traits were analyzed on 6.349 heads, 3.214 rams, and 3.135 ewes, from 2012 to 2019 using the General Linear Model (GLM) and Duncan multiple range test of SAS 9.0 software. The fixed effects used in the analysis were the sex and the birth type. The results showed that the performance of Garut Sheep based on the preweaning weight was affected significantly (P<0.05) by the sex, with the average of birth weight, 30, 60, 90 days weight and weaning weight (100 days) were 2.46 kg, 5.64 kg, 7.73 kg, 9.92 kg, 10.97 kg (rams) and 2.33 kg, 5.42 kg, 7.34 kg, 9.36 kg, and 10.28 kg (ewes). The pre-weaning weight was also significantly affected (P<0.05) by the birth type, in which  the average of birth weight, 30, 60, 90 days weight and weaning weight (100 days) were 2.96 kg, 6.49 kg, 8.98 kg, 11.29 kg, 12.52 kg (single), 2.25 kg, 5.09 kg, 6.78 kg, 8.71 kg, 9.52 kg (twin), 1.79 kg, 4.62 kg, 6.24 kg, 8.09 kg, 8.92 kg (triplet), 1.54 kg, 4.53 kg, 5.89 kg, 7.15 kg, 8.03 kg (quadruplet), and 1.51 kg, 3.84 kg, 5.23 kg, 6.58 kg, 7.15 kg (quintuplet). Based on the results, preweaning weight must be corrected by the sex and the birth type before the genetic parameters are analyzed to avoid bias of selection results.

The objective of the present study was to evaluate the physiological adaptability of pregnant doe Kacang goats in a dryland area of Indonesia. Thirty pregnant doe Kacang goats aged 2-3 years were observed. The rearing system was semiintensive without giving concentrated feeds. Local grasses and legumes such as Leucaena leucocephala leaves, Gliricidia sepium leaves, Sesbania grandiflora leaves, and drinking water were offered ad libitum. Experimental data such as respiration rate, rectal temperature, adaptability coefficient, heart rate, and heat tolerance coefficient, were collected during 2-3 months of gestation. The mean and standard deviation were calculated using a descriptive analysis method. The average humidity in the morning and afternoon and the ambient temperature in the middle of the day were outside the normal range. The THI value indicates that the experimental animals are under medium heat stress. The average values of HTC, AC, RT, HR, and RR were still typical for goats. In conclusion, although the average ambient temperature at midday and humidity in the morning and afternoon were outside of the normal range, they did not cause any effects on feed and water intake, health, and fetus growth and development of pregnant doe Kacang goats. This happened because the Kacang goat is a local breed that can adapt well to extreme environments. Therefore, pregnant doe Kacang goats in Malaka District can be allowed to graze in the paddock throughout the day and housed at night.

Rataan bobot badan setiap rumpun domba yaitu DG 34 kg, DP 21 kg, dan DL 20,5 kg. Setiap rumpun domba dianggap sebagai perlakuan dan masing – masing diulang sebanyak enam kali. Domba dipelihara dalam kandang individu yang telah dipasang kamera CCTV sebanyak dua unit. Pakan berupa hijauan segar dan air minum, diberikan secara ad libitum selama periode penelitian (06:00-18:00 WIB). Rangcangan acak lengkap digunakan dalam penelitian ini, selanjutnya data diolah dengan ANOVA melalui uji F dengan Uji Duncan sebagai uji lanjutnya.  Penelitian dilaksanakan di Laboratorium Ternak Potong Kandang Domba Fakultas Peternakan Universitas Padjadjaran sejak 29 Januari hingga 12 April 2019. Hasil penelitian menunjukkan terdapat perbedaan lama waktu makan dan ruminasi antar rumpun domba. Domba Lokal menunjukkan lama waktu makan paling sebentar setelah Domba Garut dan Domba Priangan (DL 8996,00 detik/hari, DG 13483,33 detik/hari, dan DP 16468,67 detik/hari). Lama ruminasi paling lama ditunjukkan oleh Domba Garut (16993,67 detik/hari), kemudian Domba Priangan (13718,33 detik/hari), dan paling sebentar Domba Lokal (11163,67 detik/hari). Kesimpulan dari penelitian ini adalah terdapat perbedaan lama waktu makan dan lama ruminasi dari ketiga rumpun domba.Kata kunci : Lama Makan, Lama Ruminasi, Domba Garut, Domba Priangan, Domba Lokal  ABSTRACTThis study aimed to learn about differentiation of eating and ruminating time from three tribe of sheep which is Garut’s Sheep, Priangan’s Sheep, dan also Local’s Sheep. Every sheep has equal age from 12 to 18 month with average body weigth 34 kg’s for Garut’s Sheep, 21 kg’s for Priangan’s Sheep, and 20 kg’s for Local’s Sheep. Each tribe of sheep was used as a treatment, and every treatment has repeated six time. Two CCTV’s was used to observe the behaviour of sheep with modified individual cage along observation. Observation period was start from 06:00 to 18:00 for each individual with ad libitum forages as primary food and water supply. The data were randomized using Complete Randomized Sampling Method, and evaluated using ANOVA with Duncan post-hoc test to determine the divergency. The research was held in “Laboratorium Ternak Potong Kandang Domba Fakultas Peternakan Universitas Padjadjaran” since January 29th 2019 sampai tanggal 12 April th 2019. Hasil penelitian menunjukkan bahwa setiap suku memiliki nomor yang berbeda dari pengeluaran waktu untuk makan dan memamah biak. Domba Lokal memiliki waktu makan terendah setelah Domba Garut dan Domba Priangan dengan nilai 8996,00 s / d, 13483,33 s / d, dan 16468,67 s / d masing-masing. Domba Garut memiliki jumlah waktu perenungan tertinggi dengan 16993,67 s / d, kemudian Domba Priangan dan Domba Lokal masing-masing dengan nilai 13718,33 s / d, dan 11163,67 s / d.
