This study aimed to describe and discriminate the morphostructure of Batur sheep and Wonosobo sheep with body measurements and body indices. Methods: Fourteen body measurements and nine body indices were measured from 37 Batur and 83 Wonosobo sheep. Two statistical methods of factor and discriminant analyses were computed with SPSS 25.0 program to describe the sheep's morphostructure and characterization. Result: The factor analysis in body measurements was obtained three principal components (PCs) that explain about 76.58% (Wonosobo sheep) and 73.51% (Batur sheep) of the total variance in animals' morphostructure. Meanwhile, the factor analysis in body indices was obtained on three PCs that explain about 79.16% (Batur sheep) and 95.57% (Wonosobo sheep) of the total variance in animals' morphostructure. About 95.2% of Wonosobo sheep and 92.7% of Batur sheep can be classified with body measurements (RW, SW, EL, EW, RH and TL). Meanwhile, about 75.7% of Batur sheep and 80.7% of Wonosobo sheep can be classified with body indices (TI and CI). In conclusion, Batur and Wonosobo sheep can be accurately characterized by their body measurements.

This study examined the correlation between the sheep farmer's characteristics and the animal and environmental health management practices. The data collected by direct interviews with 48 respondents in Batur Village, Banjarnegara. Indonesia. The aspects of animal (exercise, grooming, wool shearing, supplement feeding, and water drinking) and environmental (sheepfold sanitation, waste processing, and waste removal) health management practices were divided into three categories, namely low, medium, and high levels. The results showed that 83.3% of respondents were in the low-level following by medium (14.6%) and high (2.1%) levels of animal health management. Furthermore, on the environmental health management shows, 27.1% of respondents were in the low level, 60.4% in the medium level, and 12.5% in the high level. There was a significant relationship between farmers' characteristics (informal education, livestock farming experience, and the number of sheep) and animal health management practice. A significant relationship was also shown between formal education, livestock purpose, livestock experience, and number of sheep by farmers toward environmental health management practice. It may conclude that the low and medium levels of animal and environmental health management practices were dominant in Batur Village.

Concentrate supplementation is then needed to fulfill the nutrients requirement. This study was aimed to measure the performance of Aceh Cattle fed by forage and concentrate as supplementation in different levels. The study was conducted in Livestock Breeding Center for Excellent and Forage Animal Feed (BPTU-HPT) Indrapuri Aceh using 20 male Aceh Cattle aged 1.5-2.5 years. The cattle were intensively kept for 90 days and grouped based on feeding proportion of forage and concentrate with different levels, i.e., T1=100:0 as a control, T2=70:30, T3=50:50, and T4=30:70 on dry matter-based. The cattle were weighed every month and feed intake was measured. Data were analyzed by one way of ANOVA, followed by Duncan's New Multiple Range Test. The results showed that feed intake, feed efficiency, body weight gain and average daily gain of T1 was the lowest (P <0.05). The average daily gain of T3 and T4 did not significantly differ. There was a significant difference between T1 and T2. Concentrate supplementation improved the feed intake and growth performances of Aceh Cattle. The best level of concentrate supplementation on forage feed was 50:50.

The present study was undertaken to estimate correlation coefficients between biometric traits and identify best predictor of body weight in female Batur sheep from body measurements. Data on body weight and body measurements (body length: BL, chest girth: CG and withers height: WH) were collected from 73 female Batur sheep in Batur Village, Banjarnegara District, Central Java Province, Indonesia. Batur sheep were grouped into 3 categories based on their age, namely groups <1.5 years, 1.5-2.5 years and >2.5 years. The data were analyzed using simple, multiple, and automatic linear regression methods using the SPSS computer software version 25 platform. The correlation coefficient, coefficient determination, adjusted coefficient determination, residual standard error, Akaike information criterion, Bayesian information criterion, and Akaike information criterion corrected were used to determine the best regression formula for the prediction of BW. The average BW (kg), BL (cm), CG (cm), and WH (cm) of 49.27, 63.11, 91.41, and 56.82, respectively was observed in the present study. The correlation coefficients of 0.433, 0.866, and 0.369 for BW with BL, CG, and WH were observed in the present study. The best prediction of BW using two predictors (BL and GC) was BW =-56.522 + 0.509BL + 0.843CG, followed by using three predictors (BL, CG, and WH) was BW =-57.897+ 0.505BL + 0.839CG + 0.034WH, and using the only one predictor (CG) was BW =-28.443 + 0.905CG. The study revealed that CG and its combination with other linear body measurements can effectively define the body weight in Batur sheep. However, the highest R 2 of 0.782 was observed when CG and BL were used as predictors.

Menjelang perayaan Idul Adha, kegiatan perdagangan ternak meningkat. Selain pedagang tetap yang kesehariannya berjualan ternak (primary traders), juga banyak dijumpai pedagang yang hanya menjual ternak pada periode tersebut yang dikenal dengan pedagang tiban (opportunist traders). Penelitian ini dilakukan dengan cara observasi dan wawancara mendalam kepada total 59 pedagang ternak ruminansia kecil yang dipilih secara purposive sampling di wilayah Yogyakarta pada periode Idul Adha di bulan Agustus 2019. Data yang dikumpulkan meliputi demografi pedagang, pengadaan ternak serta penjualan ternak. Data dianalisis dengan analisis deskripsi kuantitatif. Rata-rata umur, jumlah anggota keluarga, dan pengalaman berternak pedagang tetap lebih tinggi daripada pedagang tiban, yaitu berturut-turut 51,29 vs 43,76 tahun, 4,94 vs 3,69 orang, dan 18,57 vs 17,95 tahun, namun waktu berdagang dan jumlah pegawainya lebih sedikit, yaitu 10,47 vs 11,09 jam/hari dan 3,81 vs 5,25 orang. Sebagian besar pedagang tetap mempunyai pendidikan sekolah dasar (38,46%) dan pekerjaan utama sebagai pedagang (66,67%), sedangkan pedagang tiban mempunyai pendidikan sekolah menengah atas (50%) dan pekerjaan utama sebagai wiraswasta (50,00%). Jenis ternak yang paling banyak dijual oleh pedangan tetap adalah ternak domba (43,59%), sedangkan pedagang tiban adalah kombinasi domba dan kambing (70,00%). Pasar hewan merupakan tempat yang paling banyak diminati oleh pedagang tetap (36,88%) maupun pedagang tiban (39,80%) dalam pengadaan ternak. Ternak domba lebih banyak ditawarkan, terjual, dan juga lebih mahal daripada ternak kambing (76,50 vs 25,43 ekor; 67,85 vs 24,36 ekor; dan Rp. 2.943.373 vs 2.402.500) dengan bobot badan yang hampir sama (29,33 vs 30,17 kg/ekor). Dapat disimpulkan bahwa periode Idul Adha memberikan peluang usaha baru secara periodik di dalam perdagangan ternak ruminansia kecil, dimana karakteristik dan kegiatan usaha yang dilakukan oleh pedangan tiban tidak jauh beda dengan pedagang tetap pada periode ini.
