3.1 retention of Proteins
The results of statistical tests show that the addition of probiotic plus herbs on different feed real (p < 0.05) against retention of Red tilapia fish protein. Results the average protein retention indicates that P1 (4,7659%) differed markedly with P0 (1,1505%) but no real different with P1 P2 (3,3455%), P3 (4,1090%) and P4 (2,1154%). The treatment gives the same results Q4 low with P0 feed without granting probiotics plus herbs.
Administering probiotics plus herbs on treatment with doses of P4 8 ml/kg of feed to give the maximum results, it is presumed the necessary bacteria concentration too much then it will give rise to overgrowth. According to the Atlas and Richard (1993) that the density of …show more content…
The value of Red tilapia fish fat retention in treatment of P4 (3,3139%) did not differ markedly with P0 (2,0605%) it is because on a P4 with a dose of probiotic treatment 8 ml/kg has a high density of bacteria causing the existence of competition in the uptake of nutrients and bacterial activity be hampered Atlas and Richard (1993). Mulyadi (2011) added that the number of bacteria that cause too much bacteria quickly experience the sporulasi so that the function and activity of the bacteria Lactobacillus SP., be not optimal absorption process and also be no maximum.
The results of statistical tests show that the treatment of the P3 (5,0710%) is a treatment with the average value of the highest fat retention but not different treatment with P1 (3,8759%), P2 (3,3889%), and P4 (3,3139%). High value retention of fat on the treatment P3 caused by the activity of lactic acid bacteria in probiotic plus herbs can provide an atmosphere of acid so that pathogenic bacteria that do not hold on to an atmosphere of acid can be eliminated and the process the process of absorption of nutrients can run well without being hindered by pathogenic bacteria (Arief,
