Status Nutrisi Mineral Rusa Totol (Axis axis) Di Lingkungan Istana Kepresidenan Bogor
Abstract
Tujuan penelitian untuk mengevaluasi status mineral rusa totol di
lingkungan Istana Kepresidenan Bogor dan melalui analisa status mineral (Ca, P,
Fe, Mn, Zn, Cu dan Pb) di tanah, pakan dan rambut rusa. Rambut merupakan
tempat terakumulasinya mineral terutama logam berat pada tubuh selain hati,
ginjal, kuku dan jaringan adiposa. Analisis rambut dikoleksi dari 15 ekor rusa
jantan yang dipilih secara acak dengan usia ±2.5 – 6 tahun. Tanah yang dikoleksi
dari sepuluh titik, contoh rumput diperoleh melalui cuplikan dari beberapa titik
lahan penggembalaan.
Kadar mineral tanah, pakan dan rambut rusa di analisa menggunakan
Atomic Absorption Spectrofotometry (AAS). Kadar mineral menunjukkan Ca dan
P pada tanah sangat rendah, kadar mineral Fe dan Pb tinggi sedangkan mineral
Mn, Zn dan Cu tanah dalam kisaran normal. Pada rumput lapang, kadar mineral
Ca, P, Cu dan Zn tergolong rendah dan belum dapat memenuhi kebutuhan rusa,
kadar mineral Fe dan Mn tinggi melebihi kebutuhan rusa totol. Mineral Ca, P, dan
Cu dapat dipenuhi dari pakan konsentrat sedangkan Zn dapat dipenuhi melalui
suplementasi mineral blok. Kadar mineral Pb rumput 0.94 ppm masih dalam batas
normal. Kadar Mineral Ca, Fe dan Mn pada rambut rusa tergolong tinggi, namun
kadar Zn dan Cu rambut rendah (P<0.01). Tingginya kadar Pb rambut diduga
terjadi oleh akumulasi Pb dalam jangka waktu panjang. The research was to evaluate the mineral status of spotted deer in the Bogor
Presidential Palace and through the analysis of mineral status (Ca, P, Fe, Mn, Zn,
Cu and Pb) in soil, feed and deer hair. Hair is a place of accumulation of minerals,
especially heavy metals in the body, apart from the liver, kidneys, nails and
adipose tissue. Hair analysis was collected from 15 male deer that were randomLy
selected with an age of ± 2.5 - 6 years. Soil is collected from ten points, grass
samples obtained by sampling from several points of grazing land.
Soil mineral content, forage and deer hair were analyzed using Atomic
Absorption Spectrofotometry (AAS). The mineral content shows that Ca and P in
the soil are very low, the levels of Fe and Pb minerals are high, while the minerals
Mn, Zn and Cu are in the normal range. In field grass, the mineral content of Ca,
P, Cu and Zn is low and has not been able require mineral needed of deer, high
levels of Fe and Mn minerals exceed the needs of spotted deer. Minerals Ca, P,
and Cu can be fulfilled from concentrate feed while Zn can be fulfilled through
mineral block supplementation. The grass Pb mineral content of 0.94 ppm is still
within normal limits. Mineral Ca, Fe and Mn levels in deer hair were high, but Zn
and Cu levels in hair were low (P <0.01). The high level of hair lead is thought to
be caused by long-term Pb accumulation.
