PENAMBAHAN ENZIM FITASE DAN VITAMIN D3 PADA RANSUM AYAM BROILER SEBAGAI UPAYA MENEKAN POLUSI FOSFOR PADA LINGKUNGAN (The Addition of Phytase and Vitamin D3 in Broiler Chicken Ration as an Efforts to Reduce Phosphorus Pollution in Enviroment)

Penelitian ini bertujuan untuk mengetahui pengaruh enzim fitase dan vitamin D3pada ransum ayam broiler terhadap efisiensi penggunaan fosfor (P) dengan cara mengukur residu fosfor (P) ekskreta. Ternak yang digunakan yaitu ayam broiler strain Lohmann sejumlah 126 ekor dengan lama penelitian 6 minggu. Perlakuan yang digunakan terdiri atas 7 perlakuan yaitu: R0 (pakan kontrol); R1 (500 FTU/ kg pakan); R2 (1000 FTU/ kg pakan); R3 (1500 FTU/ kg pakan); R4 (100 IU Vit D3/ kg pakan); R5 (200 IU Vit D3/ kg pakan); R6 (300 IU Vit D3/ kg pakan) dengan kandungan protein 21% dan energi metabolis (EM) 3000 kkal/kg. Hasil penelitian menunjukkan penggunaan enzim fitase dan vitamin D3 dalam pakan menunjukkan pengaruh berbeda nyata (P<0,05) terhadap kadar fosfor ekskreta. Hasil penelitian ini dapat disimpulkan bahwa penambahan enzim fitase pada level 1000 FTU/kg pakan dan vitamin D3100 IU/kg pakan dapat menurunkan kandungan fosfor ekskreta ayam broiler.

Abstract
This study aimed to finding out the effects of phytase and vitamin D3 in the broiler on effect to reduce phosphorus pollution on enviromental. One hundred twenty six of Lohmann strain were divided into seven treatments in the replication with six broiler each. Seven treatment were performed, namely : R0 control feed; R1 500 FTU phytase/kg feed; R2 1000 FTU phytase/kg feed;R3 1500 FTU phytase/kg feed; R4 100 IU Vitamin D3/kg feed;R5 200 IU Vitamin D3/kg feed;R6 300 IU Vitamin D3/kg feed with 21% protein and metabolisme energy (EM) 3000 kcal.kg. The results showed the addition phytase and vitamin D3 was significantly different (P<0,05) on phosphorus excrete P. The study can be concluded thet addition phytase up to 1000 FTU phytase/kg feed and vitamin D3 at 100 IU/kg feed in broiler decreased reduce phosphorus content in the excreted.
