  • Occurrence of zearalenone in maize
    Mycotoxin Research, 1993
    Co-Authors: E Oldenburg
    Abstract:

    The occurrence of zearalenone in whole plants and parts of maize usually used for Silage Making was investigated during the cultivation period of the crop. Zearalenone was detected upto several hundreds of μg/kg DM, that mainly accumulated at the end of the ripening process thus contaminating the Silages subsequently. The highest concentrations of zearalenone were observed in the leaves especially at the bottom of the plant, which may correlate with leaf necrosis increasing towards harvest. Further research is needed to clarify health risks for farm animals due to uptake of contaminated feed and possible carry-over of zearalenone and its metabolites into the food chain of man.

  • A comparative study and phage typing of Silage-Making Lactobacillus bacteriophages.
    Journal of bioscience and bioengineering, 2003
    Co-Authors: Katsumi Doi, Ye Zhang, Yousuke Nishizaki, Akiko Umeda, Sadahiro Ohmomo, Seiya Ogata
    Abstract:

    Abstract To investigate basic characteristics of 10 virulent phages active on Silage-Making lactobacilli, morphological properties, host ranges, protein composition and genome characterization were separated into five groups based on host ranges and basic properties. The seven phages of groups I, II and V were active on Lactobacillus plantarum and Lactobacillus pentosus . Phage φPY4 (group III) infected both L. casei and Lactobacillus rhamnosus . Phage φPY5 (group IV) specifically infected Lactobacillus casei . Morphologically, three phages of groups I belonged to the Myoviridae family, while seven other phages of groups II, III and V belonged to the Siphoviridae family. SDS-PAGE profiles, restriction analysis, G+C contents of DNA and Dot blot hybridization revealed a high degree of homology in each group. Clustering derived from host range analysis was closely related to results of DNA and protein analyses. These phages may be applicable to phage typing for Silage-Making lactobacilli.

  • Characterization of a Phage Resistance Plasmid, pLKS, of Silage-Making Lactobacillus plantarum NGRI0101
    Bioscience biotechnology and biochemistry, 2000
    Co-Authors: Tomoko Eguchi, Katsumi Doi, Sadahiro Ohmomo, Kanako Nishiyama, Seiya Ogata
    Abstract:

    Phage contamination has resulted in abnormal fermentation in Silage. We isolated a phage-resistant strain, Lactobacillus plantarum NGRI0101 from Silage. The strain carried two plasmids, pLKL (6.8 kb) and pLKS (2.0 kb). By curing and retransformation of the plasmids, we clarified that pLKS has phage resistant activity, characterized as no adsorption inhibition. pLKS has 2,025 bp and three orfs, orf123, orf132, and orf918. The predicted amino acid sequence of the orf918 product showed high similarity to those of Rep proteins of Pediococcus halophilus plasmid pUCL287 and Lactobacillus acidophilus plasmid pLA103. The replication origin (ori) was upstream from orf918. There was no gene similar to typical phage resistant genes encoded by known plasmids. The phage resistance of L. plantarum NGRI0101 may possibly be due to a plasmid-encoded abortive infection.

  • Relationship between the Quality of Italian Ryegrass Silage and the Presence of Phages for Silage-Making Lactobacilli
    Journal of the agricultural chemical society of Japan, 1994
    Co-Authors: Naoko Kaneshige, Katsumi Doi, Sadahiro Ohmomo, Samu Tanaka, Ye Zong, Kanako Nlshiyama, Seiya Ogata
    Abstract:

    Forty-one samples of Italian ryegrass Silage were examined for the presence of phages in Silage-Making lactobacilli. For the detection of phages, 94 strains of Lactobacillus plantarunm and five strains of L.casei, all of which were newly isolatedfrom Silage, five type strains of L. plantarum, three type strains of L.casei, and five commercially available strains were used. Only ten samples (24% of the Silages) had phages. More than 45% of the strains tested, all L. plantarum, were infected by phages. Samples in which phages were detected usually were moist, had a high pH, and produced little lactic acid. In Silages with pH4.l or below, no phages were detected. The higher the moisture content, the greater was the possibility of phage infection. The results showed that contamination by phages deteriorated the quality of the Silages, and that phage control is needed.

  • Silage-Making and Recent Trend of Dairy Farming in Thailand
    Japan Agricultural Research Quarterly: JARQ, 2002
    Co-Authors: Sadahiro Ohmomo, Sunee Nitisinprasart, Supanit Hiranpradit
    Abstract:

    Based on statistical data such as the number of cattle head, the amount of raw milk production and demand, regional and monthly quantity of raw milk production, etc., the characteristics of dairy farming in Thailand wereoutlined. It is suggested that feeding of good-quality Silage throughout a year is the most effective method to increase the amount of raw milk production in Thailand. However, the difficulty in Making good-quality Silage in Thailand was pointed out from the results of analyses of the microbial flora of the Silages prepared in Thailand. Therefore, the selection of suitable lactic acid bacteria by using an evaluation system of lactic acid bacteria for Silage-Making in Thailand was proposed.

  • Selection of Killer Yeasts (Kluyveromyces lactis) to Prevent Aerobic Deterioration in Silage Making
    Journal of dairy science, 1993
    Co-Authors: Hiroko K. Kitamoto, Sadahiro Ohmomo, Tadaatsu Nakahara
    Abstract:

    Killer spectra were investigated to select killer yeast strains to inhibit the growth of wild yeasts that cause aerobic deterioration of Silage. Kluyveromyces lactis IFO 1267 was characterized by its rapid killing activity and wide spectrum against the target yeasts. Crude killer protein produced by K. lactis IFO 1267 or inoculation of the cell itself inhibited the growth of the target strain, Saccharomyces cerevisiae IFO 0304 (in liquid or in solid culture), particularly when lactose was used as carbon source instead of glucose.

  • Silage review: Safety considerations during Silage Making and feeding
    Journal of Dairy Science, 2018
    Co-Authors: Keith K. Bolsen
    Abstract:

    ABSTRACT Silage-related injury knows no age boundary as workers and bystanders of all ages have been killed in Silage accidents. Even the best employee can become frustrated with malfunctioning equipment and poor weather conditions and take a hazardous shortcut, or misjudge a situation and take a risky action. At least 6 hazards are encountered in managing Silage in bunker silos and drive-over piles that endanger lives: tractor or truck rollover, run-over by or entanglement in machinery, fall from height, crushing by an avalanche or collapsing Silage, Silage gases, and complacency or fatigue. These hazards are presented in detail along with accounts of 14 individual case studies involving several of them. Guidelines that can dramatically reduce the risk of serious injuries or fatalities from each of the hazards are presented. Every farm, feedlot, dairy, and Silage contractor should have written safety policies and procedures for their Silage program, and they should schedule regular meetings with all their employees to discuss and demonstrate safety. The most important goal in every Silage program is to send all employees home safely to their families at the end of the day.

    2003
    Co-Authors: Feyisitan Modupe Taylor
    Abstract:

    The experiment to evaluate the physical characteristic of Silage produced is different low cost Silage Making materials in South West Nigeria was carried out of at the university of Agriculture, Abeokuta, Ogun State from June to September 2011. Four different low cost containers and five lining were used to produce Silage from Panicum maximum (guinea grass). The containers were plastic, plank boxes, baskets and Trench while the linings were polythene sheets, concrete, mud, banana leaves and the unlined as the control. The plants were cut back and harvested before flowering. They were chopped, wilted and ensiled for 91days. When the containers were opened, data on physical characteristics such as odour, colour, degree of mouldiness, moisteness, were collected. There were significant differences for the different container's effect on the colour of Silage, odour, degree of mouliness and moisture only at P

When the containers were opened, data on physical characteristics such as odour, colour, degree of mouldiness, moisteness, were collected. There were significant differences for the different container's effect on the colour of Silage, odour, degree of mouliness and moisture only at P<0.05. Also differences of the effects of different lining on the physical properties of Silage was observed except for moistures where it was observed that it was significant meaning that there different linings affects the physical properties of Silage I the same way. Plank containers lined with banana leaves had the highest mean value in terms of colour and odour. In conclusion, plank containers lined with banana leaves can be selected for the highest physical properties of Silage
