The Relationship

The villous height to crypt depth (V:C) ratio is one of the most significant parameters which is associated with the nutrients’ absorption and greater body weight. The objective of this study was to assess the relationship between V:C ratio, gut bacteria counts and production parameters in broiler chickens. A total of 100 individual broilers were randomly selected from a farm with 40,000 Ross 308 chickens and slaughtered for sampling at three different ages including 14, 28 and 37 day old. Villous height and crypt depth were measured for each section of the small intestine to calculate V:C ratio. Intestinal score and gut microbiology including total coliforms, lactic acid bacteria and Salmonella prevalence were assessed. At day 37, besides those parameters, the carcass, breast, legs and wings were taken for weight measurements. Leg and breast color was also measured. Data were statistically analyzed by STATA software to explore the relationship between V:C and those parameters. The results showed the positive correlation between V:C of duodenum and the number of lactic acid bacteria at 28 days of age (P < 0.05). Moreover, the leg yield was negatively related to the V:C ratio of jejunum (P < 0.05). No significant correlations were found between V:C ratio and other parameters. The results indicated the potential of controlling V:C ratio to improve gut health and meat quality of broiler chickens and thus, further studies should be conducted to fully evaluate these correlations.

Cereal products fermented by lactic acid bacteria are documented first in Egypt and Iraq during 2000 - 3000 B.C. These are one of the oldest fermented foods. In 1907, Elie Metcnikoff was the first scientist who not only observes but also put forward the scie ntific basics of fermentation. Then to explore gut bacteria intensive researches were made in late 1940s. In 2006 FAO and WHO give the complete definition of probiotics, living microbes beneficial for health provided in feed. For treatment of Coccidiosis p robiotic combinations of different microbes such as Lactobacillus, Bifidibacterium and Streptococcus are used now days. Coccidiosis, a parasitic disease mainly of poultry sector, caused by Eimeria specie’s. Coccidiosis causes serious damage to the intestin al epithelium resulting in diarrhea. This problem can be effectively controlled by the use of feed probiotics.

Probiotic Lactic Acid Bacteria

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).

Abstract In prokaryotes, a major contributor to genomic evolution is the exchange of genes via horizontal gene transfer (HGT). Areas with a high density of HGT networks are defined as genetic exchange communities (GECs). Although some phenotypes associated with specific ecological niches are linked to GECs, little is known about the phenotypic influences on HGT in bacterial groups within a taxonomic family. Thanks to the published genome sequences and phenotype data of Lactic Acid Bacteria (LAB), it is now possible to obtain more detailed information about the phenotypes that affect GECs. Here, we have investigated the relationship between HGT and internal and external environmental factors for 178 strains from 24 genera in the Lactobacillaceae family. We found a significant correlation between strains with high utilization of sugars and HGT bias. The result suggests that the phenotype of the utilization of a variety of sugars is key to the construction of GECs in this family. This feature is consistent with the fact that the Lactobacillaceae family contributes to the production of a wide variety of fermented foods by sharing niches such as those in vegetables, dairy products, and brewing-related environments. This result provides the first evidence that phenotypes associated with ecological niches contribute to form GECs in the LAB family.

Synbiotics can prevent gastrointestinal infections in broilers. This work studies the effect of a Synbiotic on broilers. One-day-old male broilers were divided into groups: Control; Synbiotic; Synbiotic + S. Typhimurium; Synbiotic + C. perfringens; Synbiotic + S. Typhimurium + C. perfringens; S. Typhimurium; C. perfringens; and S. Typhimurium + C. perfringens. Histopathological analysis revealed that the Synbiotic promoted longer villi, less deep crypts, and better villi-crypt ratio. Broilers treated with the Synbiotic, infected with pathogens or not, had healthier mucosa. In groups infected with pathogens, the frequency and intensity of histopathologic lesions were lessened often in groups treated with the Synbiotic. The Synbiotic group had higher lactic acid bacteria counts than the Control group on day 39, and the isolation frequency of S. Typhimurium was lower (p < 0.05) in the Synbiotic-treated groups. On day 18, mucosa, villi, villi-crypt ratio, crypt, and feed intake were influenced by Enterobacteriaceae. However, on day 39 (end of the trial), those parameters were influenced by lactic acid bacteria. The Synbiotic influenced morphological modifications in the duodenal mucosa, which in turn gave the broilers the ability to resist infections caused by S. Typhimurium and C. perfringens, by inhibiting their growth and decreasing the intensity and frequency of histopathological injuries.

The aim of this study was to evaluate the potential of two probiotic preparations, containing live lactic acid bacteria (Lactococcus lactisCECT 539 andLactobacillus caseiCECT 4043) and their products of fermentation (organic acids and bacteriocins), as a replacement for antibiotics in stimulating health and growth of broiler chickens. The effects of the supplementation of both preparations (with proven probiotic effect in weaned piglets) and an antibiotic (avilamycin) on body weight gain (BWG), feed intake (FI), feed consumption efficiency (FCE), relative intestinal weight, and intestinal microbiota counts were studied in 1-day posthatch chickens. The experiments were conducted with medium-growth Sasso X44 chickens housed in cages and with nutritional stressed Ross 308 broiler distributed in pens. Consumption of the different diets did not affect significantly the final coliform counts in Sasso X44 chickens. However, counts of lactic acid bacteria and mesophilic microorganisms were higher in the animals receiving the two probiotic preparations (P<0.05). In the second experiment, although no differences in BWG were observed between treatments, Ross 308 broilers receiving the probioticLactobacilluspreparation exhibited the lowest FCE values and were considered the most efficient at converting feed into live weight.

The Relationship

SummaryIn suitable media the relationship between the citrate content and the acetoin formed by the growth ofStreptococcus lactisvar.diacetilactisNCDO 1007 is linear. An assay method for citrate is described which is based on this relationship. It has been used to assay the residual citrate in cultures of lactic acid bacteria and, therefore, to assess the ability of these bacteria to dissimilate citrate. Some suitable media for the test are described.
