ABSTRACT
Aim: This study aimed to determine the use of probiotics Bifidobacterium spp. and Lactobacillus casei as alternative antibiotic growth promoters (AGPs) to improve growth performance and business analysis.
Materials and Methods: This study used a completely randomized factorial design. The first factor was the time of administration (1, 2, 3, and 4 weeks) and the second was the use of probiotics (control without probiotics; 0.1% AGP and 0.5% Bifidobacterium spp. + 0.25% L. casei). One hundred and eighty laying hens (Lohmann strain), of 30 weeks old, were divided into 12 treatment groups, composed of five replicates, each consisting of three laying hens.
Results: The results showed that using 0.5% Bifidobacterium spp. + 0.25% L. casei in weeks 1 and 2 showed the lowest feed intake (FI) (112.11-112.19 g/day), the highest egg weight (60.28 g) in the 1st week, the lowest feed conversion ratio (FCR) (2.21-2.23), and highest feed efficiency (44.75-45.25%) for 3-4 weeks, and the highest hen-day production (86.66-86.90%) for 3-4 weeks and the most profitable business analysis (IDR. 30,353).
Conclusion: Based on the results, it can be concluded that the addition of 0.5% Bifidobacterium spp. + 25% L. casei probiotics can be used as a substitute for AGP; it can reduce the FI and FCR, increasing egg weight, feed efficiency, and hen-day production, as well as illustrating the results of the most profitable business analysis.
