Fecal Microbial Population and Growth in Broiler Fed Organic Acids and Palm Fat-Composed Diet

Abstract

Organic acids (OA) are natural constituents of plant and animal tissues and their uses as feed additives are now being studied worldwide. Organic acids consisted of different acids and mixtures of several acids have an antimicrobial function and promote the growth performance of animals. The current experiment was designed to study the inhibitory activity of the organic acids, palm fat (PF), a combination of organic acids-palm fat (OAPF) against various pathogens and investigate the performance in dietary inclusion of OAPF in broilers. A feeding trial was conducted to determine the growth performance and microbial population in the dietary inclusion of OAPF in broilers. A total number of 96 one-day-old chickens (Cobb 500) were used in this study and divided into two treatment groups with six replicates per treatment. The treatment group was T1 (diet without OAPF) and T1OA (diet with OAPF). The differences among treatment means were tested using an independent t-test. The results showed that T1OA had approximately two-fold inhibitory activity against Escherichia coli E-30 compared to T1. Broilers fed diet supplemented with OAPF had higher (p<0.05) final body weight (BW) and total weight gain (WG) compared to broilers fed T1. Broiler fed with T1OA had lower (p<0.05) feed conversion ratio (FCR) than T1. Inclusion of OAPF in the diet also increased (p<0.05) the lactic acid bacteria (LAB) and reduced (p<0.05) Enterobacteriaceae (ENT) cell population. The inclusion of OAPF in the diet showed significantly improved nutrient digestibility and had a beneficial effect on the growth performances of the broiler chickens with a positive effect on the bacterial population in GIT.

Immune Status and Growth of Broiler Fed Diet with Microparticle Protein Added with Natural Acidifier

“…The decreased fecal N τ -MH excretion can be correlated with the improved amino acids digestibility such as arginine until phenylalanine in P2, but only arginine, lysine, and methionine significantly increased in P3 (Table 2). The present study was consistent with the result of Goh et al (2020), who reported that dietary inclusion of the mixture of organic acid-palm fat improved nutrient digestibility and had a beneficial effect on the growth performances of broiler chicken. An interesting result found in this research that BWG was not affected by the reduced feed consumption (Table 3) because it was covered by the increased protein and amino acid digestibility (Table 2).…”

Antioxidant Enzymes and Growth of Broiler Fed Microparticle Protein Diet with Inulin or Lactobacillus acidophillus Supplementation

“…Feeding either MP-DTE or MP-La diets improved growth performances supported by higher body resistance and defense, as indicated by higher circulating levels of GSH-Px and SOD. The present results were consistent with the previous study that nutrient digestibility was beneficial for the improvement of growth performances in a broiler-given diet with an organic acid-palm fat mixture (Goh et al, 2020). A result that would be important in the present study was that feed consumption was not affected by any treatment, but BWG increased by the feeding effect of either dahlia inulin or L. acidophilus.…”

Evaluasi Nutrisi Tepung Ikan Rucah yang Diolah Menggunakan Probiotik dan Precursor-Prebiotik dalam ransum Ayam Broiler

“…Postbiotic yang disekresikan oleh bakteri asam laktat (BAL) dapat berupa asam laktat, asam propionate, asam butirat, bakteriosin, enzim, senyawa antioksidan dan berbagai senyawa metabolit lainnya (Thanh et al, 2009;Manin, 2010;Thu et al, 2011;Loh et al, 2014;Chuah et al, 2019;Yang et al, 2020). Postbiotik dilaporkan dapat berperan sebagai natural biopreservatives (Jama andVaradaraj 1999, Hidayatulloh et al, 2019), dan antibiotic growth promoters baik pada ayam petelur, maupun ayam pedaging (Thanh et al, 2009;Loh et al, 2014;Goh et al, 2020).…”

“…Bakteri asam laktat dilaporkan dapat menghasilkan postbiotic berupa asam-asam organic, enzim ataupun bakteriosin dilaporkan dapat memperbaiki sistem pencernaan dan penyerapan nutrient serta menyeimbangkan populasi bakteri di dalam saluran pencernaan (Thu et al, 2011;Goh et al, 2020) sehingga dapat memperbaiki performan ayam broiler. Postbiotik yang dihasilkan oleh BAL dapat digunakan untuk menggantikan antibiotic growth promoters serta telah terbukti dapat meningkatkan produktivitas dan kesehatan saluran pencernaan ayam petelur dan ayam pedaging (Thanh et al, 2009;Loh et al, 2014;Goh et al., 2020).…”
