Abstract

A feeding trial was conducted to study the use of natural limestone meal originated from Bukit Kamanglocated at Agam district of West Sumatra to substitute fresh water oyster shell as the main source ofcalcium in diet of laying hens. The mineral feed formula, as treatments, composed of limestone in combinationwith freshwater oyster shell in five different percent ratios: 100:0; 75:25; 50:50; 25:75 and 0:100. The mineralswere mixed in the level of 6 % into basal diet composed mainly corn, rice bran and concentrates. The fiveexperimental diets were then fed to 150 laying hens. They were divided into 5 groups; each group wassubdivided into 3 replicates groups containing 10 hens. Parameters measured included: feed intake, eggproduction, FCR, eggshell quality, Ca and P retention, tibia bone mineralization. Results showed the nutritivevalues of limestone of Bukit Kamang as mineral source of laying hen diet were found not significantlydifferent from those of oysters shell. The hens fed with diet supplemented with Bukit Kamang’s limestonetended to give better laying performances than those of supplemented with fresh water oyster shell. Thelaying performances, egg shell quality and Ca and P retentions did not significantly improved, when limestonewas mixed by oyster shell.

Abstract

Samples of limestone composites were measured for hardness in 5 difference colors: black, darkblue, blue, light blue and white. Limestone was then ground and particle sizes of meal were measured.The meal were mixed with other locally available materials to produce 5 difference mineral formulas:P1: 100% limestone meal, P2: 50% limestone meal + 50% fresh water oyster shell meal, P3: 35%limestone meal + 30% fresh water oyster shell meal + 35% bone meal, P4: 35% limestone meal + 30%fresh water oyster shell meal + 34.2% bone meal + 0.5% salt + 0.3% micro minerals and P5: 100% freshwater oyster shell meal. The formulas were stored for 12 weeks. Samples were taken weekly foranalyzing of moisture content and physical properties. By a feeding trial the five mineral formulas weremixed in the level of 6 % into basal diet and fed to 150 laying hens for 24 weeks. Parameters measuredincluded body weight, feed intake, egg production and FCR. Results showed that the composites ofBukit Kamangs’ limestone had difference hardness. The strongest was found by the black composite of23.4 HRc-C or 245.0 BHN. The meal products contained large particles (>0.42 mm) of 17.8%. Moisturecontent of mineral formulas increased during storage, but their physical properties were no significantchanges. The highest moisture increase was found by the product of 100% limestone, but it could bereduced by mixing with oyster shell meal and bone meal. The best laying performances (P<0.05) werefound by the hens fed with diet supplemented with mineral formula containing limestone, fresh wateroyster shell and fortified with micro minerals.

Abstract

The present research was carried out to study the diversity of mineral contents of wild forages and to evaluate the beneficial effect of mineral feed supplement formulated by using locally available materials on the performances of beef cattle. The present research was initiated by analyzing mineral contents of wild forages grown around Limau Manis campus areas. Forage samples were collected at 9 sampling areas scattered at plantation, conservation and idle lands. Samples were then analyzed for macro minerals of Ca, P, Mg, K, Na, and S and micro minerals of Co, Cu, Fe, Mn, Se, and Zn. Feeding trial was then conducted to evaluate the beneficial effect of supplementation of local mineral formulas (LMF) produced by using locally available materials on the performances of cattle. Feeding trial was conducted for 6 weeks by using 9 Simmentals cross bred heifers. The trial consisted of 3 treatments, i.e., P1: only grass without supplementation, P2: grass + LMF and P3: grass + mineral premix enriched LMF. Variables measured were: body weight, feed intake, FCR, feed cost and net return. Results showed that the highest macro mineral content of wild forages was Na of about 13.05±2.22 g/kg, varied from 4.1 to 23.8 g/kg, followed by K (11.09±1.43 g/kg) and Ca (6.10±1.09 g/kg DM). Three minerals of Mg, P, and S were found in relatively small concentrations of 1.34±0.30, 0.83±0.23, and 0.17±0.01 g/kg, respectively. Fe, Mn, Cu and Zn were found in relatively high concentrations. The highest concentration of micro minerals was Fe of about 613.8±128.9 mg/kg, followed by Mn of 143.9±23.3 mg/kg, while Zn and Cu were found in relatively small amount of about 31.3±5.5 and 13.2±2.5 mg/kg, respectively. Heifers supplemented with LMF (P2) and mineral premix enriched LMF (P3) showed higher body weight gain, lower FCR and net return than those cattle fed only grass (P1). The most profitable feeding strategy was by supplementation of heifers with mineral premix enriched LMF.Key words: wild forage quality, local mineral formula, ruminant mineral nutrition

Abstract

Penelitian ini bertujuan untuk mempelajari potensi ketersediaan dan kandungan zat makanan hijauan yang tumbuh di lahan kampus Universitas Andalas di luar lahan UPT Fakultas Peternakan. Penelitian ini dilakukan dengan metode survei dan pengamatan langsung ke lapangan, Data hasil penelitian kemudian dianalisis secara statistik menggunakan analisis sidik ragam, yang terdiri atas 3 perlakuan dan 3 ulangan. Sedangkan, parameter yang diukur adalah produksi biomass, komposisi botanis, kapasitas tampung, kandungan zat makanan (Air, BK, PK, SK dan LK) dan kandungan mineral makro (Ca, Na, P, S, Mg dan K) serta mineral mikro (Cu, Zn, Fe, Mn, Co, dan Se). Hasil penelitian menunjukkan bahwa kandungan zat makanan, produksi biomass, kapasitas tampung dan kandungan mineral (makro dan mikro) menunjukkan perbedaan yang tidak nyata (P>0,05) pada tiga topografi. Jenis tanaman pada topografi datar dan miring didominasi oleh alang-alang (Imperata cylindrica) masing-masing 69,3% dan 56,2% sedangkan pada topografi gelombang didominasi oleh rumput pahit (Axonopus compressus) yang mencakup sekitar 54,4%. Pada topografi datar kandungan protein kasarnya lebih tinggi 9,8% BK. Pada topografi gelombang PK nya tinggi 9,4% BK sedangkan pada topografi miring PK paling rendah 8,9% BK. Produksi hijauan segar pada daerah yang datar merupakan produksi hijauan segar yang paling tinggi yaitu 65356,9 kg/ha/th. Sedangkan produksi hijauan kering tertinggi adalah pada topografi miring 12180,13 kg/ha/th. Kapasitas tampung per hektar (ST/ha) pada setiap topografi berkisar antara 1,68 (ST/ha) sampai 2,22 (ST/ha). Kapasitas tampung tertinggi adalah pada lahan miring 2,22 (ST/ha) dan disusul oleh lahan yang bertopografi datar 2,13 (ST/ha). Sedangkan pada lahan yang bergelombang memiliki kapasitas tampung terendah yaitu 1,68 (ST/ha). Kandungan mineral pada setiap topografi juga menunjukkan perbedaan yang tidak nyata. Mineral makro tertinggi terdapat pada lahan yang bertopografi datar P 1,03 g/kg BK, Mg 1,53 g/kg BK, K 13,03 g/kg BK, Na 15,84 g/kg BK, S 0,17 g/kg BK kecuali Ca 8,13 g/kg BK. Sedangkan kandungan mineral mikro tertinggi berada pada topografi miring Zn 36,16 mg/kg BK, Fe 804,00 mg/kg BK, Mn 171,52 mg/kg BK kecuali Cu 16,03 mg/kg BK. Dari hasil penelitian dapat disimpulkan bahwa hijauan yang tumbuh di lahan kampus Universitas Andalas Limau Manis di luar lahan UPT Peternakan berpotensi sebagai pakan ternak ruminan. Rumput yang berasal dari topografi datar relatif lebih baik dari kandungan zat makanan maupun mineralnya.Kata kunci : Produksi hijauan, kapasistas tampung, komposisi zat makanan
