“…Kerja BAL ini akan mencegah terjadinya infeksi dan meningkatkan kecernaan pakan dalam saluran pencernaan. Hasil perkembangan BAL akan meningkatkan asam lemak rantai pendek dan asam laktat, menurunkan pH dan mengaktifkan enzim pencernaan, sehingga saluran pencernaan menjadi lebih sehat dan meningkatkan kecernaan protein (Kim et al, 2015).…”

Penelitian bertujuan untuk mengkaji perubahan kualitas dan kadar amonia litter pada pemeliharaan ayam broiler akibat penambahan sinbiotik dari inulin ekstrak umbi gembili dan bakteri Lactobacillus plantarum. Materi yang digunakan adalah ayam broiler day old chick (DOC) unsexed sebanyak 144 ekor dengan bobot awal 45,68 ± 1,52 g dialokasikan ke dalam rancangan acak lengkap (RAL) dengan 4 perlakuan 6 ulangan. Perlakuan yang diberikan berupa penambahan sinbiotik yaitu sebagai berikut T0 : ransum basal (tanpa penambahan sinbiotik); T1 : sinbiotik 1 ml/100g ransum; T2 : sinbiotik 2 ml/100g ransum dan T3 : sinbiotik 3 ml/100g ransum. Parameter yang diamati adalah kadar air, pH, suhu, dan amonia litter. Data yang diperoleh dianalisis dan data yang menunjukkan pengaruh perlakuan yang nyata di uji lanjut dengan uji wilayah Duncan. Hasil penelitian menunjukkan bahwa penambahan sinbiotik signifikan (P≤0,05) menurunkan kadar amonia dan pH litter, dan signifikan (P≤0,05) meningkatkan kadar air litter, sedangkan terhadap suhu litter tidak berpengaruh signifikan (P>0,05). Kesimpulan dari penelitian ini adalah penambahan sinbiotik sebanyak 2 ml/ 100g ransum dapat memperbaiki kualitas dan kadar amonia litter.

“…Butyric acid (C 4 H 8 O 2 ) is the most important source of energy to the epithelial cells; it required for normal epithelial cell development and has antibacterial activity in the gastrointestinal tract [15]. Many poultry researchers intensively studied butyric acid; diets supplemented with butyric acid improved feed efficiency and BW gain of broilers [16].…”

This study was conducted to compare the effects of single and synergistic organic acids (formic (F) and butyric (B) acids) on the performance and lymphoid organs of broiler chicks. In total, 450 one-day-old ISA JA57 chicks were assigned randomly to nine groups, each of five replicates (10 chicks/replicate): The control group, without added acids; groups 2 and 3, with 0.2% and 0.3% formic acid, respectively; groups 4 and 5, with 0.2% and 0.3% butyric acid, respectively; group 6, with 0.2% formic acid and 0.3% butyric acid; group 7, with 0.2% butyric acid and 0.3% formic acid; groups 8 and 9, with 0.2% butyric and formic acids and 0.3% butyric and formic acids, respectively. The control group received tap water, and other treatment groups received acidified drinking water, as previously described. The results indicated that treatment resulted in a significantly higher (p < 0.05) average live weight and weight gain at four weeks of age than in the control group. Nevertheless, group 7 showed significant decreases in the feed conversion ratio compared with the other treatments between four and five weeks of age. The carcass percentage was highest when B3, F3B2, and B2 were added to the drinking water, whereas control and F2B3 showed lower carcass percentage than the other treatments. At 42 days of age, the addition of organic acids to the drinking water of broilers had significant effects on the bursa of Fabricius and thymus percentages, but no effect on the spleen percentage. Water acidification by F and B alone and in combination did not affect poultry performance. However, it improved the lymphoid organ weight, indicating improved immunity and carcass percentage at 42 days of age.

“…A decrease in pH could also be achieved by adding formic acid to diets. As reviewed by Kim et al [10], supplementation of formic acid was reported to affect the microbial community and lead to increased performance and nutrient digestibility in broiler chickens. Likely, the addition of formic acid to CaCO 3containing diets and the use of Ca-formate in uences the microbial community in the digestive tract, possibly through changes in digesta pH [11,12].…”

Background Diet acidification, dietary calcium ( Ca ) level, and phytase supplementation are known influences on the microbial community in the digestive tract and on phosphorus ( P ) utilization of broiler chickens. Effects of dietary factors and microbiota on P utilization may be linked because microorganisms produce enzymes that release P from phytate ( InsP 6 ), the main source of P in plant feedstuffs. This study aimed to detect linkages between microbiota and InsP 6 degradation by acidifying diets (i.e., replacing Ca carbonate (CaCO 3 ) by Ca formate or adding formic acid to CaCO 3 -containing diets), varying Ca levels, and supplementing phytase in a three-factorial design. We investigated i) the microbial community and pH in the digestive tract, ii) prececal ( pc ) P and Ca digestibility, and iii) InsP 6 degradation. Results All factors under investigation influenced digesta pH and the microbiota composition. Predicted functionality and relative abundance of microorganisms indicated that diets influenced the contribution of the microbiota on InsP degradation. Values of InsP 6 degradation and relative abundance of the strains Lactobacillus johnsonii and Lactobacillus reuteri were correlated. Phytase supplementation increased pc InsP 6 disappearance, with differences between Ca levels, and influenced concentrations of lower inositol phosphate isomers in the digestive tract. Formic acid supplementation increased pc InsP 6 degradation to myo -inositol. Replacing CaCO 3 by Ca-formate and the high level of these Ca sources reduced pc InsP 6 disappearance, except when the combination of CaCO 3 +formic acid was used. Supplementing phytase to CaCO 3 +formic acid led to the highest InsP 6 disappearance (52%) in the crop and increased myo -inositol concentration in the ileum digesta. Supplementing phytase leveled the effect of high Ca content on pc InsP 6 disappearance. Conclusions The results point towards a contribution of changing microbial community on InsP 6 degradation in the crop and up to the terminal ileum. This is indicated by relationships between InsP 6 degradation and relative abundance of phosphatase-producing strains. Functional predictions supported influences of microbiota on InsP 6 degradation. The extent of such effects still remains to be clarified. InsP 6 degradation can also be influenced by pH effects caused by dietary concentration and solubility of the Ca sources.
