PRODUKSI PANAS DAN RETENSI ENERGI PADA KERBAU PACUAN YANG MENDAPATKAN LAMA LATIHAN BERBEDA [Heat Production and Energy Retention of Racing Buffaloes Subjected to Different Length of Exercise]

ABSTRAK Penelitian yang bertujuan untuk mengetahui produksi panas (kebutuhan energi) dan retensi energi kerbau pacuan (makepung) pada kerbau lumpur (Bubalus bubalis) yang dilatih dengan lama waktu latihan yang berbeda telah dilakukan di Desa Candikusuma, Kecamatan Melaya, Kabupaten Jembrana (Bali). Rancangan Split plot (3 x 4) dengan rancangan dasar rancangan acak kelompok digunakan dalam penelitian ini, dimana berat tubuh sebagai petak utama sedangkan lama waktu latihan sebagai anak petak. Petak utama terdiri dari tiga macam berat tubuh yaitu : kerbau dengan berat tubuh 309 ± 4,29 kg (B1); 350,94 ± 6,21 kg (B2) dan 393,94 ± 8,07 kg (B3), sedangkan anak petak terdiri dari empat tingkat lama waktu latihan yaitu L0, L1, L2 dan L3 berturut-turut 0, 5, 10 dan 15 menit/hari. Hasil penelitian menunjukkan bahwa peningkatan produksi panas dan penurunan retensi energi secara nyata (P<0,05) dipengaruhi oleh peningkatan lama waktu latihan pada kerbau. Kebutuhan energi untuk istirahat sebesar 32,73 MJ/ekor/hari atau setara dengan 0,39 W0,75 MJ/ekor/hari. Kebutuhan tersebut meningkat sesuai dengan peningkatan lama waktu latihan 5; 10 dan 15 menit/hari berturut-turut menjadi 1,06; 1,22 dan 1,50 kali dari kebutuhan energi saat istiratahat, sedangkan perhitungan kebutuhan energi untuk hidup pokok didapatkan sebesar 28,11 MJ/ekor/hari atau setara dengan 0,36 W0,75 MJ/ekor/hari. Hasil penelitian ini dapat disimpulkan bahwa (1) Pemberian latihan menyebabkan terjadinya kecenderungan penurunan persentase lemak dan peningkatan persentase protein tubuh kerbau; (2) Terjadinya penurunan retensi lemak, retensi protein dan retensi energi dengan meningkatnya lama latihan; (3) Kebutuhan energi untuk hidup pokok dan istirahat pada kerbau jantan masing-masing sekitar 0,36 W0,75 dan 0,39 W0,75 MJ/ekor/hari; dan (4) Kebutuhan energi pada kerbau jantan akan meningkat 1,66 kali dari kebutuhan hidup pokok bila lama waktu latihan sampai 15 menit/hari.

A completely randomized block design which was arranged in 3 x 4 split plot was applied in this research. There were three main plots in which each plot had one group of the animals that were categorized on the bases of their average live weights (± SD) i.e. group of B1 (309.44 ± 4.29 kg); B2 (350.94 ± 6.21 kg); and B3 (393.94 ± 8.07 kg), and four levels of exercise used as subplot. The levels of exercise were the buffaloes which were not subjected exercise (L0), those subjected exercise for 5 (L1), 10 (L2) and 15 minutes (L3). Each treatment had 4 buffaloes as replication. Results of the research revealed that heat production significantly increased and energy retention significantly decreased with the increase in duration of exercise subjected to the buffaloes (P<0.05). The average requirement of energy for resting was 32.73 MJ/head/day or equivalent to 0.39 W0.75 MJ/head/ day (per kg metabolic live weight). The energy requirement increased with the increasing of exercise duration i.e. for 5; 10; 15 minutes exercise required energy of 1.06; 1.22 and 1.50 times to energy for resting, respectively, while requirement of energy recorded for maintenance was 28.11 MJ/head/day or equivalent to 0.36 W0.75 MJ/head/day. From the results of the research it could be concluded that : (1) the exercise subjected to the buffaloes tended to cause the decrease in body fat reserves and to increase body protein compared to those which were not subjected to exercise; (2) as duration of exercise was increased there were increase in the retention of fat, protein and energy ; (3) requirements of energy for maintenance and resting for male buffaloes were 0.36 W0.75 and 0.39 W0.75 MJ/head/day, respectively; and (4) energy requirement of the male buffaloes increased 1.66 times to that required for maintenance when the length of exercise was lengthened up to 15 minutes per day.

PENAMPILAN KELINCI YANG DIBERI PAKAN DASAR RUMPUT DENGAN SUPLEMTASI KONSENTRAT DAN LEMAK TELO

ABSTRACT The experiment that aimed for knowing the influence of increase tallow into concentrate diet for rabbits performance that are given basic diet field grass had done. This experiment used Randomized Completely Design (RCD) with five treatments and each treatment consisted of four replicates. Those five treatments were concentrate diet without tallow (treatment A) and concentrate diet with 2%, 4%, 6% and 8% tallow (followed as treatment B, C, D and E). The research had done into diet consumption, energy consumption, protein consumption, crude fiber consumption, calcium consumption, phosphor consumption, body weight gain, final body weight and FCR. The result of this experiment showed that diet consumption, crude fiber consumption, calcium consumption, phosphor consumption, body weight gain and final body weight for all treatments were non significant different (P&gt;0.05). Energy consumption and FCR were significant different (P&lt;0.05). From the result can be concluded that the rabbits that have concentrate diet treatment with 6% tallow resulted the highest body weight gain and the lowest FCR. </em

Additional turmeric powder (curcuminoid) into traditional ration to improve the productivity of bali pig

Bali Pig is one of germplasm whose existence is very limited until now. This is due to the very low growth and breeding compared to other types such as Landrace pigs, Duroc, and Laghwhite. However, Bali pig has an advantage among others such as able to utilize lack quality feed so it is suitable to maintain in rural areas. To keep the existence of Bali pig, a necessary attempt needed to avoid extinction. One of its ways is to make improved feed by adding turmeric powder (curcuminoid). The benefits of giving curcuminoid are able to increase the appetite, increase the utilization of nutrients such as fats, proteins, and carbohydrates. This research method used a Complete Randomized Design (CRD) with 4 treatments and 4 replications. The treatments were: Treatment A: swine rations that did not contain turmeric powder (extract curcuminoid), Treatment B: swine rations contained turmeric powder (extract curcuminoid), 0,02 ml/1 kilogram body weight, Treatment C: swine rations contained turmeric powder (extract curcuminoid 0.04 ml/1 kilogram body weight), and Treatment D: swine rations contained turmeric powder (extract curcuminoid)

EFFECT OF INCLUSION CALCIUM-PALM FATTY ACID (Ca-PFA) ON GROWTH PERFORMANCE AND PROFILE OF BODY FATTY ACID OF BROILER

A study of effect of inclusion of calcium-palm fatty acid (Ca-PFA) in the diets on growthperformance and profile of body fatty acid has been conducted for 4 weeks in broiler. A total of 160birds were used in present experiment which was arranged in a Completely Randomized Design with 4treatments and 5 replications (8 birds each). Dietary inclusions of Ca-PFA of 0, 5, 10 and 15% werereflected as R0, R1, R2 and R3, respectively. Results of the experiment showed that growth performancebased on the feed consumption significantly decreased (p&lt;0.05), but there were no significant (p&gt;0.05)effect for final body weight, carcass percentage and carcass composition. The inclusion of Ca-PFA in thediet was not affected the saturated fatty acid (p&gt;0.05), but showed significant effect on unsaturated fattyacid and omega-3 fatty acid (p&lt;0.05). Body fat distribution was not affected by inclusion level of Ca-PFA at a level of 15%. In conclusion, the inclusion of Ca-PFA in the diet until 15% decreased feedconsumption and produced similar growth performance, however it increased unsaturated fatty acid,omega-3 fatty acids and decreased body fat of broiler

Level FCR in 0,04 ml/1 kilogram bodyweight curcuminoid treatment  showed the most efficient result and the dry matter digestibility showed significant results (P <0.01). However, organic matter digestibility, crude fiber and protein digestibility showed a non-significant (P> 0.01) result. Overall, ration treatment with curcuminoid 0,04 ml/1 kilogram bodyweight showed the best results

Serial case report: Becker’s muscular dystrophy phenotype with dilated cardiomyopathy in patients with out-of-frame deletion involving exons 38-43 of DMD gene

Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) are X-linked recessive allelic muscular dystrophies due to mutations of the DMD gene, showing more severe and milder phenotype, respectively. Here we present, two brothers, ages 23 years old (case 1) and 19 years old (case 2) who presented with clinical symptoms typically associated with BMD, including dilated cardiomyopathy in the first case and mild cardiac enlargement in the second. Muscle symptoms were moderate enabling independent ambulation of both patients until the present. Dystrophin protein was patchy on immunohistochemistry staining confirming the diagnosis of BMD. However, genetic analysis using Multiple Ligation-dependent Probe Amplification (MLPA) identified out-of-frame deletions involving exons 38-43 of the DMD gene in both cases. Here, we report a case series with an exception to the reading frame rule due to mutations affecting the central rod domain of the DMD gene. © 2021, ASEAN Neurological Association. All rights reserved
