This study was performed to determine the growth of Java bulls fed rice straw and concentrates at different levels of protein. Twelve heads of Java bulls, one and a half years old, with initial body weight ranging from 113.83-191 kg were used in this experiment. They were grouped into four replications based on the initial body weight. The rice straw (30%) and concentrates (70%) diet containing three different levels of protein (8.27; 11.03 and 14.43%) were fed during nine weeks. Data gathered were the average daily gain and the average body measurements (chest girth, shoulder height and body length). Result of this study showed that the increase of protein levels from 8.27 to 14,43% did not significantly influence the average daily gain, shoulder height, and body length of Java bulls (P > 0.05), but it influenced daily chest girth (P < 0.05). The average daily gain (ADG), shoulder height and body length were 0.633 kg, 0.08 cm, and 0.09 cm, respectively. The highest average of daily chest girth of Java bulls was T2 = 0.19 cm, followed by T3 = 0.15 cm, and T1 = 0.12 cm. It is concluded that the increase levels of protein from 8.27 to 14.43% did not affect the average daily gain, shoulder height and body length of Java cattle. However, the highest chest girth was achieved by Java cattle which fed concentrate containing 11.03% of protein. Key Words: Growth, Java Bull, Rice Straw, Concentrate, Levels of Protein

Penelitian tentang edible portion dan commercial cut pada sapi Peranakan Ongole (PO) yang diberi pakan konsentrat dengan level yang berbeda telah dilaksanakan pada bulan Juli 2008 sampai dengan Oktober 2008. Penelitian dilakukan di Laboratorium Ilmu Ternak Potong dan Kerja Fakultas Peternakan Universitas Diponegoro Semarang. Penelitian ini bertujuan untuk melihat pengaruh pakan yang diberikan untuk ternak dengan level konsentrat sedang (T1) dan tinggi (T2) terhadap besarnya bobot potongan komersial dan banyaknya edible portion yang dihasilkan.Materi yang digunakan adalah 8 ekor sapi PO yang berumur rata-rata 1,5 tahun dengan bobot badan awal rata-rata 297 + 26 kg (CV = 8,75%). Bahan pakan yang digunakan adalah jerami padi urinasi dan konsentrat (dedak padi dan ampas bir). Metode penelitian yang digunakan adalah rancangan acak lengkap (RAL) dengan 2 perlakuan dan 4 ulangan. Data yang diperoleh kemudian dianalisis menggunakan uji F. Parameter yang diukur antara lain bobot potong, bobot karkas, bobot masing-masing potongan komersial, bobot edible portion karkas dan non karkas.Hasil analisis data menunjukkan bahwa tidak ada pengaruh yang nyata pada masing-masing perlakuan. Bobot potong 286,25 kg (T1) dan 290 kg (T2). Bobot karkas panas 157,80 kg (T1) dan 161,39 kg (T2). Bobot masing-masing potongan komersial adalah chuck 38,89 kg (T1) dan 38,02 kg (T2), shank 16,72 kg (T1) dan 15,62 kg (T2), rib 15,13 kg (T1) dan 17,37 kg (T2), plate 9,00 kg (T1) dan 9,90 kg (T2), sirloin 17,54 kg (T1) dan 12,77 kg (T2), shortloin 8,80 kg (T1) dan 12,22 kg (T2), flank 2,45 kg (T1) dan 3,11 kg (T2), round 42,49 kg (T1) dan 46,84 kg (T2). Persentase edible portion karkas 79,27 % (T1) dan 77,89 % (T2). Persentase edible portion non karkas 31,82 % (T1) dan 31,71 % (T2). Persentase edible portion total 57,23 % (T1) dan 56,73 % (T2). Kesimpulan yang diperoleh adalah pemberian konsentrat dengan level yang berbeda menghasilkan potongan komersial dan bobot total edible portion yang relatif sama.

Penelitian ini bertujuan untuk mengetahui komposisi kimia daging setelah diberi perlakuan pakan dengan kualitas yang berbeda. Materi penelitian menggunakan 15 ekor kambing Kacang jantan dengan bobot badan awal rata-rata 14,28 Â± 3,36 kg (CV = 23,55%). Metode penelitian menggunakan rancangan acak kelompok (RAK), dengan 3 perlakuan pakan dan 5 kelompok ternak berdasar bobot badan awal. Perlakuan pakan tersebut adalah T1 (Protein Kasar (PK) 9,20% : Total Digestible Nutrients (TDN) 54,67%), T2 (PK 11,67% : 58,61%), dan T3 (PK 18,33%: TDN 65,23%). Parameter yang diamati adalah komposisi kimia daging yang terdiri atas kadar air, abu, protein, lemak, dan kolesterol yang diambil dari otot Longissimus dorsi (LD) dan Biceps femoris (BF) kemudian dirata-rata. Data hasil penelitian dianalisis dengan analisis variansi, dan dilanjutkan dengan uji wilayah berganda duncan apabila ada perbedaan. Hasil penelitian menunjukkan bahwa kambing Kacang yang diberi pakan dengan kualitas berbeda, menghasilkan komposisi kimia daging yang tidak berbeda nyata (P>0,05). Rata-rata kadar air, abu, protein, lemak, dan kolesterol daging kambing Kacang pada penelitian ini adalah 76,01%; 0,66%; 19,40%; 2,57%; dan 81,38 mg/100 g daging. Simpulan penelitian ini adalah komposisi kimia daging kambing Kacang dengan kualitas pakan protein dan energi yang berbeda relatif sama.

This study was set up to evaluate the performance of Java and Ongole Crossbred (OC) bulls fedconcentrate and rice straw. A total of four Java bulls and four OC bulls were used in this experiment. Thebulls were fed concentrates (50% of the total dry matter feed requirement) and rice straw (ad libitum).The concentrates were consisted of rice bran, beer waste product, copra meal, minerals, with crudeprotein (CP) and total digestible nutrients (TDN) contents of 15.32% and 73.09%, respectively. Theaverage daily gain (ADG), dry matter intake (DMI), protein and energy intake, and feed conversion ratio(FCR) were observed. The results of this study showed that the ADG, DMI, CP and TDN intake, andFCR were not significantly different (p> 0.05). The ADG of Java and OC bulls were 0.58 kg and 0.78kg, respectively. The averages of DMI, CP and TDN intake were 6.59 kg (2.09% of BW), 0.81 kg and4.34 kg for Java bulls whereas for OC bulls were 6.42 kg (2.11% of BW), 0.78 kg, and 4.20 kg,respectively. The FCR of Java bulls was 11.49 and those of OC bulls was 9.21. It can be concluded thatJava and OC bulls raised intensively and fed concentrate and rice straw had the similar performance.

An experimental study was carried out to evaluate the implication of early fattening of Kejobong goats by improving feeding quality on methane production and meat production. Sixteen goats (8 young and 8 mature) were raised for 4 months study period. Nested design was used in this study, with young and mature as a nest factor, and diet (G7C3: 70% grass and 30% concentrate and G3C7: 30% grass and 70% concentrate) as the treatments. The main parameters observed were DMI, BWG, carcass (CWG) and meat weight gain (MWG), and methane emission. The results showed, the young goat fed G3C7 was higher than that fed G7C3 in DMI. The BWG’s of goats fed G3C7 were higher than those fed G7C3, but there was no difference between ages in BWG. The FCR of young goat fed G3C7 was lower than that fed G7C3. The DMI of mature goat was higher than young goat, but there were no differences between the ages in DM digestibility, carcass weight and meat weight gain. The young and mature goats fed G3C7 was significantly lower than that of G7C3 in methane emissions per unit of BWG (0.28 vs 0.40 and 0.36 vs 0.53, respectively), in methane emissions per unit CWG (0.60 vs 0.93 and 0.79 vs 1.47, respectively), and methane emission per unit MWG (0.89 vs 1.42 and 1.16 vs 2.19, respectively). It can be concluded that fattening young Kejobong goats by improving feed quality is more environmentally friendly than fattening the mature ones.

Publisher : Chemical Engineering Diponegoro University

Feeds are very important for the growth of animals due to it is contained almost all nutrients needed by the animals. Feeds are not only influence the animal growth but also their physiological response. The objective of this research was to investigate the effect of tofu cake as an additional feed replacing commercial concentrate on local male sheep’s water consumption and their physiological response such as body temperature, pulse, and rate of exhalation. The selected 15 local male sheep (in the age of 8-9 month with initial weight 12.53 ± 1.19 kg) were housed individually in cage for about 14 weeks include 4 weeks adaptation period and 10 weeks experiment.The experiment was conducted using completely randomized design with 3 different treatments and 5 times repetition; T0 = ad libitum grass field + commercial concentrate, T1= ad libitum grass field + wet tofu cake, T2= ad libitum grass field + dried tofu cake, and water were provided in ad libitum method. Data analysis was done using analysis of variance (ANOVA) followed by Duncan’s multiple range test. The result shown that dried tofu cake as an additional feed replacing commercial concentrate was able to increasing the water consumption of local male sheep. Meanwhile the physiological test performed stable in the present of wet or dried tofu cake. Keywords— alternative feed, physiological response of male sheep
