PENGEMBANGAN PROBIOTIK BAKTERI ASAM LAKTAT DARI LIMBAH IKAN YANG BERPOTENSI MENURUNKAN KADAR KOLESTEROL DAGING AYAM BROILER STRAIN HUBBART

Abstract

The  aims  of  this  research  is  to find   the  influence  of  giving   isolate  probiotic   BAL Streptococcus  thermophillus from the fish  waste toward the broilers' appearance of woof and the degree of broilers'  cholesterol. The research materials are 40 roosters of broiler Strain  Lohmann, production  of PT Multi  Breeder Adirama  at the age of 1 week. The probiotic of isolate treatment of Lactate Acid  Bacteria (BAL) which is used in this research is Streptococcus  thermophillus bacteria in from of freeze dying which comes from  Nutrition Biochemical Laboratory, Veterinary Faculty of UGM The treatment I is as the control (without BAL), the number of BAL in treatment  II is  10⁶ CFU/ml,  the number of BAL in treatment III is 10⁷ CFU/ml, the number of BAL in treatment IV is 10⁸ CFU/ml. The data collection for the degree of cholesterol is done after 28 days. The data which is collected of woof and the degree of broilers'  cholesterol.  The research result: the treatment of giving  lactate  acid bacteria of Streptococcus thermophillus caused the decrease  of the degree of broilers' cholesterol significantly and the best level of BAL is 10⁸ CFU/ml.
