Membrane and Resins Permeation for Lactic Acid Feed Conversion Analysis

This study aimed to determine the effect of probiotics of lactic acid bacteria in drinking water on feed consumption, weight gain and feed conversion ratio of broiler chickens. This research is an experimental research. The experimental animals used in this study were 28 male broiler chickens strain Cobb 700 aged 20 days. P0 was not given the addition of probiotic lactic acid bacteria, P1 was given the addition of probiotic lactic acid bacteria Lactobacillus acidophilus in 1ml/liter drinking water, P2 was given the addition of probiotic lactic acid bacteria Lactobacillus casei in drinking water 1ml/liter, P3 was given the addition of probiotic lactic acid bacteria Lactobacillus fermentum in drinking water 1ml/liter, P4 was given the addition of probiotic lactic acid bacteria Lactobacillus plantarum in drinking water 1ml/liter, P5 was given the addition of probiotic lactic acid bacteria Pediococcus in drinking water 1ml/liter, P6 was given the addition of probiotic mix lactic acid bacteria in drinking water 1ml /liter. Collecting data for the last 1 week by weighing the remaining consumption of feed given and weight gain of broiler chickens. The data obtained were analyzed using the Analysis of Variant (ANOVA) statistical method and continued with Duncan. Based on the results of the calculation of the amount of feed consumption and weight gain in broiler chickens, it showed that the administration of probiotic lactic acid bacteria 1ml/liter of water in broiler chickens could increase body weight gain, reduce feed conversion rates but did not reduce broiler feed consumption (p<0.05).

Growth Trial

Two growth trials and a short-term metabolism trial were conducted in broiler chickens in the period of 22 to 42 days of age in order to evaluate the effects of two dietary levels of L-lactic acid (1.03 or 2.06 g/kg) and microbial 6-phytase (750 U/kg), added either separately or in combination, on growth rate, feed conversion, dressing percentage and utilization of selected nutrients. In the first growth trial, six different dietary treatments were added to a basal grower diet containing 19.4% crude protein and a reduced level of dietary phosphorus (P) (5.9 g total and 2.9 g non-phytate P per kg). Single administration of L-lactic acid did not show any positive effect on the growth rate or feed conversion. In contrast, phytase addition to a low-P grower diet resulted in the increased final weight of birds and higher feed conversion. This beneficial effect was markedly stronger when the microbial phytase was added to the diets containing L-lactic acid. Based on two-factor analysis of variance, microbial phytase significantly increased the mean final weight by 6.5% (P < 0.01) and significantly improved feed conversion from 1.877 to 1.829 (P < 0.05). In the second growth trial, the same six dietary treatments were added to a basal diet containing a standard level of dietary P (6.7 g total and 4.0 g non-phytate P per kg), but the level of crude protein was reduced to 17.0%. L-lactic acid alone did not show any positive effects on performance. Phytase supplementation alone resulted in numerical improvement of the final weight (+1.1–2.4%), but a higher effect was observed in the diets containing L-lactic acid. In agreement with the reduced final weights of broilers fed the low-protein diets, markedly higher values of feed/gain ratio were noted. In the metabolism trial, selected dietary treatments were involved to evaluate the effects of L-lactic acid and microbial phytase, added either separately or in combination, on the digestibility of nitrogen (N) and fat as well as on the retention and excretion of N and P. Apparent digestibility of N and fat in the low-P diets was not affected by dietary treatments. Retention and utilization of N were numerically higher in all treatments fed low-P diets when compared to the treatment fed a standard diet, but the differences were not significant. Retention of P was numerically higher in all treatments fed low-P diets. When compared to the standard diet, the combination of phytase and L-lactic acid increased daily P retention by 37.6%. P excretion was significantly (P < 0.05) reduced in all treatments fed low-P diets supplemented by both test products, either separately or in combination. A numerical decrease in N excretion was noted in both treatments fed low-protein diets.

Aerobic Stability

The effect of inoculation on nutrient content, fermentation, aerobic stability, and beef cattle performance for whole-plant corn silage treated with a commercial product (blend of homo- and heterofermentative lactic acid bacteria, BSM, blend of Enterococcus faecium, Lactobacillus plantarum, and Lactobacillus brevis, DSM numbers 3530, 19457, and 23231, resp.), was compared to a control treatment with no silage additives (CT). The material had a DM of 323 g/kg, crude protein, and water-soluble carbohydrate concentrations of 87.9 and 110.5 g/kg DM, respectively. BSM increased the fermentation rate with a significantly deeper pH (P<0.01), a significant increase in the total organic acids concentration (P<0.05), more lactic acid (P<0.01), and numerically more acetic acid compared to CT. BSM significantly decreased the concentrations of butyric acid (P<0.01), ethanol, and ammonia-N compared to the CT. BSM-treated silage decreased DM by 3.0 % (P<0.01) and had a higher digestible energy and a higher metabolizable energy concentration by 2.3 (P<0.01) and 1.00 % (P<0.05), respectively, compared to untreated silage. Aerobic stability improved by more than 2 days in BSM silage. The DM intake of silage treated with BSM increased by 6.14 %, and improved weight gain and the feed conversion by 8.0 (P<0.01) and 3.4%.

ABSTRACT This study aimed to select lactic acid bacteria (LAB) as a potential probiotic that producing anti‒microbial compounds in order to treat motile aeromonads septicemia diseases caused by Aeromonas hydrophila on catfish Clarias sp. and evaluated its performance on gnotobiotic catfish. The in vitro assay was done to select several LAB isolates based on antagonistic activity against pathogenic bacteria. The selected isolate was tested in vivo to observe their ability to improve growth performances of catfish. The study was conducted with five treatments consists of K‒ (normal catfish without addition probiotic, without challenge test), K+ (normal catfish without addition of probiotic, with challenge test), Np (normal catfish with addition of probiotic and challenge test), G (gnoto catfish without addition of probiotic, with challenge test), and Gp (gnoto catfish with addition of probiotic and challenge test). The results showed that the addition of Pediococcus pentosaceus E2211 as selected probiotic could increase survival rate, specific growth rate, and immune response towards infection of A. hydrophila. The best survival rate after challenge test was obtained in Np and Gp treatments (88.46%), followed by G treatment (65.38%), while the K+ was only 53.84%. The conclusion of this study was P. pentosaceus E2211 potentially used as a probiotic candidate for normal and gnotobiotic catfish. The presence of normal microflora with P. pentosaceus E2211 in Np treatment showed the best probiotic performance with daily growth rate 3.28%, feed conversion ratio 1.79, and total intestinal bacteria reached 108 CFU/mL significantly different from other treatments (P<0.05).Keywords: Aeromonas hydrophila, catfish, LAB, probiotic, screening ABSTRAKTujuan penelitian ini adalah menyeleksi bakteri asam laktat (BAL) sebagai probiotik potensial penghasil senyawa antimikrob guna menanggulangi penyakit motile aeromonad septicemia akibat Aeromonas hydrophila pada ikan lele Clarias sp. dan evaluasi kinerjanya pada ikan lele gnotobiotik. Pengujian in vitro dilakukan untuk menyeleksi beberapa isolat BAL sebagai kandidat probiotik berdasarkan aktivitas antagonis terhadap bakteri patogen. Isolat terpilih kemudian diuji in vivo untuk mengetahui kemampuannya dalam meningkatkan performa tumbuh ikan lele. Penelitian ini menggunakan rancangan acak lengkap dengan lima perlakuan, yaitu: K‒ (lele normal tanpa probiotik dan tanpa tanpa diuji tantang), K+ (lele normal tanpa probiotik dan diuji tantang), Np (lele normal diberi probiotik dan diuji tantang), G (lele gnoto tanpa probiotik dan diuji tantang), dan Gp (lele gnoto diberi probiotik dan diuji tantang). Hasil penelitian menunjukkan pemberian probiotik terpilih BAL Pediococcus pentosaceus E2211 mampu meningkatkan sintasan, laju pertumbuhan, dan respons imun ikan lele terhadap infeksi A. hydrophila. Sintasan terbaik pascauji tantang diperoleh pada perlakuan Np dan Gp yaitu sebesar 88,46%, diikuti perlakuan G sebesar 65,38%, sementara pada K+ hanya mencapai 53,84%. Kesimpulan dari penelitian ini ialah isolat BAL terpilih P. pentosaceus E2211 berpotensi sebagai kandidat probiotik untuk ikan lele normal dan lele gnotobiotik Clarias sp.

The aim of the study was to determine the effect of dietary supplementation of organic acids on the performance, intestinal histomorphology, and blood biochemistry of broiler chicken. The birds in the control group were fed the basal diet whereas in other treatment groups basal diet was supplemented with 2% butyric acid , 3% butyric acid , 2% fumaric acid , 3% fumaric acid , 2% lactic acid , and 3% lactic acid . Broiler chicken fed diets supplemented with organic acids had significantly improved body weight gains and feed conversion ratio. No effect on cumulative feed consumption was observed. The addition of organic increased villus height in the small intestines but the differences were not significant in case of the ileum. Serum calcium and phosphorus concentrations were increased but no effect on the concentration of serum glucose and cholesterol, serum glutamic pyruvic transaminase (SGPT), and serum glutamic oxaloacetate transaminase (SGOT) was observed. The results indicated that the organic acid supplementation, irrespective of type and level of acid used, had a beneficial effect on the performance of broiler chicken.

This study investigated the effect of lactic acid bacteria (LAB) on growth performance, glutathione turnover, aflatoxin B1 (AFB1) residue and AFB1-DNA adduct in growing lambs. Diets were a 2 × 2 factorial design, including AFB1 at 0 or 100 µg/kg and LAB at 0 or 3 × 109 cfu/kg. Results showed that AFB1 decreased (P < 0.05) feed intake (FI), body weight gain (BWG), and activities of glutathione (GSH), glutathione s-transferases (GSTs) and glutathione reductase (GR) in liver and duodenal mucosa, whereas these parameters were increased (P < 0.05) by supplemental LAB. AFB1 increased and LAB decreased the feed conversion ratio (P < 0.05). Interactions (P < 0.05) were found on BWG, liver GSTs and mucosal GSH. LAB decreased (P ≤ 0.001) AFB1 residue in liver, kidney, plasma and faeces and AFB1-DNA adduct in kidney, plasma and faeces. It can be concluded that LAB can partially protect against AFB1 toxicity by facilitating glutathione turnover and reducing AFB1 toxicity in lambs.

And Migration

After experimetnal damage to the retina with a variety of procedures Müller cell hypertrophy and migration occurs. According to Kuwabara and others the reactive process in these injuries is evidenced by a marked increase in amount of glycogen in the Müller cells. These cells were considered originally supporting elements with fiber processes extending throughout the retina from inner limiting membrane to external limiting membrane, but are known now to have high lactic acid dehydrogenase activity and the ability to synthesize glycogen. Since the periodic acid-chromic acid-silver methenamine technique was shown to demonstrate glycogen at the electron microscope level, it was selected to react with glycogen in the fine processes of the Müller cell that ramify among the neural elements in various layers of the retina and demarcate these cells cytologically. The Rhesus monkey was chosen as an example of a well vascularized retina and the rabbit as an example of a avascular retina to explore the possibilities of the technique.
