Phosphorus Requirement

<p>This experiment was conducted to ditermined phosphorus content in the feed of giant gouramy <em>(Osprhonemus gouramy). </em>Four semipurified diet containing isoprotein (41,0%) and isoenergy (10.0 kcal/g protein) but different in phosphorus content were prepared. Diet containing phosphorus at the level of 0,32, 0,63, 0,89 and 1,06% respectively. Fish weighing 21-25 g/ind was stocked at a density of 4 ind./aquarium. Fish was fed at a satiation level three times daily. Fish were reared for 40 days and sampling was done in every 10 day. Result of this study shows that growth performance of fish were increase with the increasing of phosphorus level in the diet till of level (0,89%). Make up of rate phosphor more than 1,06% in the diet will negating the growth. It can be concluded that giant gouramy require phosporus at the level of 0,63-0,89% for maximal growth.</p> <p>Key words : Phosphor, giant gouramy, <em>Osphronemus goruamy, </em>mineral</p> <p> </p> <p>ABSTRAK</p> <p>Penelitian ini dilakukan untuk menentukan kebutuhan ikan gurame <em>(Osphronemus gouramy) </em>akan mineral fosfor. Pakan yang digunakan dalam penelitian ini adalah pakan semimumi dengan kadar protein 41,0% dan rasio energi- protein 10 kkal/g protein. Pakan yang digunakan memiliki kandungan fosfor berturut-turut sebesar 0,32, 0,63, 0,89 dan 1,06%. Ikan gurame yang digunakan berbobot awal antara 21-25 g/ekor dan panjang tubuh awal 8,97-13,45 cm/ekor, dipelihara pada akuarium berukuran 50x40x35 cm dengan kepadatan 4 ekor/akuarium. Ikan diberi pakan 3 kali sehari secara <em>satiation </em>selama 40 hari. Setiap 10 hari sekali dilakukan penimbangan bobot tubuh ikan. Hasil penelitian menunjukkan bahwa performan pertumbuhan ikan gurame meningkat dengan meningkatknya kadar fosfor dalam makanan sampai pada tingkat 0,89%. Peningkatan kadar fosfor diatas tingkat tersebut berdampak negatif terhadap pertumbuhan. Pertumbuhan maksimal didapat pada ikan yang diberi pakan dengan kadar fosfor 0,63-1,06%.</p> <p>Kata kunci : Fosfor, ikan gurame, <em>Oshpronemus gouramy, </em>mineral.</p>

Within the context of maximizing the use of dietary phosphorus, a growing-finishing pig study was conducted to determine the optimal total dietary calcium (Ca) to digestible phosphorus (dP) ratio and to verify the possibility of mineral phosphate removal during the finishing period on growth performance and mineral status. The potential for replacing chemical and mechanical bone properties by dual energy X-ray absorptiometry (DXA) measures on non-dissected feet was also verified. Three Ca to dP ratios (2.2:1, 2.5:1 and 2.8:1) within two dP levels (P+, P–) were fed during 91 days to 84 pigs. The grower and finisher P+ diets contained 3.0 and 2.4 and P– diets contained 2.5 and 1.7 g dP/kg, respectively. Growth performance and blood serum mineral content were independent of treatments, except that 2.2:1 impaired finisher feed conversion ratio compared to 2.5:1 and 2.8:1. Urinary P concentration increased by 37% in 2.2:1 compared to 2.5:1 and 2.8:1. Maximal load on bone and DXA mineral density were reduced in 2.2:1 compared to 2.8:1. Bone ash and volumetric density were reduced in 2.2:1 and 2.5:1 compared to 2.8:1. Diet P– reduced bone ash, maximal load, volumetric density and DXA bone mineral content and density. No interaction was observed between Ca and dP level. Therefore, 2.2:1 was insufficient for an efficient metabolic use of P, 2.5:1 was sufficient to maximize growth performance and 2.8:1 further improved bone mineralization. Increasing dietary Ca did not impair bone zinc content. Diets P– without supplemented mineral phosphates during the finisher period resulted, per pig, in a decrease of its use by 65% and of the calculated P excretion by 41%, without impaired growth performance. Finally, DXA data responded to dietary treatments as did labor intensive chemical and mechanical bone properties.
