Abstract:
The study focuses on the method and the problems about quantitative analyses in the research on Lactobacillus acidophilus after its addition to commercial poultry-feed, whose rough grinding is not suitable for the "IDF Standard quantitative method for lactic acid bacteria count at 37°" employed in dairy products. Poultry-feed was prepared every month. A sample was collected before and after adding Lactobacillus acidophilus, while analyses were carried out respectively at T 0, 15, and 28 days after the food storage at 4-6°C.
The best outcome (more 30% of recovered cells compared to the standard method) resulted from samples subjected to the homogenization and the addition of Skim Milk Powder.
