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.
Background and Objectives: Use of antibiotics as growth promoters in animal feeds has been restricted due to the residues in poultry products such as egg and meat, furthermore to the antibiotic resistant of pathogenic bacteria. The prohibition of their use opens the opportunity for the use of non-antibiotic feed additives such as probiotics. The objectives of this study were to investigate the effect of the addition of Lactobacillus casei WB 315 and crude fish oil (CFO) to diets on growth performance, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), low density lipoproteins (LDL), high density lipoprotein (HDL), and cholesterol levesl of broiler chickens. Materials and Methods: In this research, one-day old male broiler chicks were used and divided equally into four groups, namely a basal diet without L. casei WB 315 and without CFO (P0), basal diet supplemented with 0.5% L. casei WB 315 of total broiler basal feed (1.2 × 109 cfu/ml) and without CFO (P1), basal diet supplemented without L. casei WB 315 and 1% CFO of total broiler basal feed (P2), and basal diet supplemented with 0.5% L. casei WB 315 of total broiler basal feed (1.2 × 109 cfu/ml) and 1% CFO of total broiler basal feed (P3) for 35 days. Results: The results of addition 0.5% Lactobacillus casei WB 315 (1.2 × 109 cfu/ml) and 1% CFO of total broiler basal feed after 35 days showed significant difference among treatment in feed efficiency (p<0.05), feed conversion ratio (p<0.05), feed consumption (p<0.05), EPA (p<0.05), DHA (p<0.05), increase HDL (p<0.05), reduced the LDL (p<0.05), and reduce cholesterol (p<0.05) in meat broiler chicken. Conclusion: It is concluded that the addition of L. casei WB 315 and crude fish oil (CFO) could significant improve the growth performance (feed efficiency, feed conversion ratio, feed consumption) and could significantly improve EPA, DHA and increase HDL and decrease LDL in meat poultry product.
Background and Objectives: An experiment was designed to determine the effect of using lactic acid bacteria as alternative antibiotic growth promoters on external and internal quality of egg’s Coturnix coturnix japonica. Materials and Methods: Coturnix coturnix japonica (n=240, 14 weeks of age) were randomly distributed into six treatment groups. The treatments were P0 (free antibiotic feed), P1 (free antibiotic feed with 1 gram antibiotic growth promoters (AGP)/100kg feed), P2 (free antibiotic feed with 5 gram probiotic/100kg feed), P3 (free antibiotic feed with 10 grams probiotic/100kg feed), P4 (free antibiotic feed with 5 gram probiotic/200L drinking water), and P5 (free antibiotic feed with 10 gram probiotic/200L drinking water). Probiotic contained Lactobacillus casei (L. casei) and Lactobacillus rhamnosus (L. rhamnosus) culture (1.2 x 108 CFU/gram). To assess the quality parameters, twenty eggs were randomly collected from each treatment at the end of the experimental period, and the data were analysed using one way Anova. Results: Results of the external quality indicated that egg’s weight, length, and width, along with the shell weight and thickness were significantly different (P<0.05) after treatment. Likewise, the results of internal egg quality indicated that yolk color, height, width, and length, together with the albumen height, width, length, index and haugh unit were significantly different (P <0.05) after treatment. Conclusion: It was concluded from this research that dietary supplementation with probiotic which contains L. casei and L. rhamnosus could be used in laying Japanese quail with benefit on external and internal egg quality.
The purpose of this study was to determine the use of probiotics Lactobacillus acidophilus and Bifidobacterium sp on feed consumption and Hen Day Production (HDP), layer was infected with Escherichia coli. About 120 layers at 25 weeks of age were randomized into six treatments. The treatment consisted of factors a (infection and non-infection Escherichia coli) and factor b (basal feed, AGP and probiotics). The results of the study gave probiotics an effect (p <0.05) on feed consumption, HDP and egg weight. Infection factors have an effect (p <0.05) on HDP but have no effect (p> 0.05) on feed consumption and egg weight. There was interactions between probiotic and infection factors (p <0.05) on HDP and egg weight but there was no interaction (p> 0.05) between probiotic and infection factors on feed consumption. The highest feed consumption was found in the treatment of infectious probiotics is 114.7g, the highest HDP was treated with non-infectious probiotics is 98.6%, the highest egg weight was treated with non-infectious probiotics is 60.5 g. It could be concluded that the administration of probiotics can produce good production performance and high profits.

The increasing need for protein, both meat and eggs, still continues to increase. Antibiotics addition can increase egg growth and production. Based on Law No.18 of 2009 along with Law No.41 of 2014 concerning existing livestock, there is a prohibition on the use of antibiotics mixed with feed. The use of probiotics mixed with feed, is used to increase livestock productivity. This study aims is to determine the effect of Bacillus subtilis probiotics addition on egg weight, albumen height and haugh unit values. 18 Laying hens aged 39 weeks were randomized into 3 treatments with 8 reiterations. The treatment consisted of P0 without the addition of probiotics, P1 with the addition of Bacillus subtilis 0.1 gram / kg of feed probiotics and P2 with the addition of Bacillus subtilis 0.2 gram / kg of feed probiotics. The results of the analysis using the test (ANOVA) showed a significant difference (p <0.05) to the egg weight value, the albumen height values were significant (p <0.05) and (p <0.05) in the haugh unit value . In conclusion the addition of probiotics in concentrations of 0.1 and 0.2 grams can increase the value of egg weight, albumen height and haugh unit.

Senyawa antibiotik tersebut digunakan sebagai growth promotor dalam jumlah yang kecil yaitu 1 g/ 400 g pakan dapat meningkatkan efisiensi pakan dan hasil produksi ternak sehingga dengan penggunaan bahan aditif tersebut peternak dapat memperoleh keuntungan lebih besar (Ariyanti dan Supar., 2005). Ayam petelur adalah ayam yang dipelihara dengan tujuan untuk menghasilkan produksi telur. Biaya terbesar yang harus dikeluarkan dalam produksi usaha peternakan ayam petelur adalah biaya pakan dengan presentase 60-70% dari usaha peternakan ayam petelur, oleh karena itu perlu dilakukan upaya untuk meningkatkan efisiensi penggunaan pakan ternak dan salah satu diantaranya adalah penambahan probiotik (Djaya dan Hidayat., 2013). Probiotik merupakan mikroorganisme hidup yang mampu memberikan efek menguntungkan kesehatan inangnya. Pemberian probiotik dapat memberikan efek menguntungkan seperti berkompetisi dengan mikroflora inang, mengurangi efek Tersedia Online di http://www.jurnal.unublitar.ac.id/ index.php/briliant
