This study was conducted to examine the effects of dietary cellulose levels on growth, nitrogen utilization, the retention time of diets in the digestive tract, and caecal microflora of 2-month-old Single Comb White Leghorn male chickens fed 3 purified diets that contained 0, 3.5% and 10% cellulose in equal amount of nutrients for 7 days. Body weight gain and nitrogen utilization were significa...

The digestive tract must supply the factors necessary for the existence of any micro-organism that finally becomes established. These factors include a favorable temperature, a constant supply of nutrients and essential fluids: In this situation the micro-organisms benefit from the environment and the animal benefits by maintaining a microflora that does not cause any disease state. There are g...

Fungal agents, especially yeasts, are resident in digestive system as microflora and they can invade the mucosal tract in animals with predisposing factors. The prevalence of the resident fungal flora in the digestive tract of healthy broilers and layers during April to September 2008 was investigated. The samples were taken from the preventriculus, jejunum and cecum contents of 120 birds and c...

This work is devoted to the use of probiotics in growing broiler chickens and problem obtaining poultry products high biological properties, produced with minimum antibiotic chemical substances that can harm both consumer environment. World practice shows gradual rejection feed antibiotics. The ban on antibiotics does not lose its relevance Russia. due growth demand for livestock obtained witho...

this study examined the effects of two bacteria (bacillu subtilis bp6 and lactobacillus plantarum lp3) on survival, growth and digestive tract microflora of achanthopagrus latus larvae with different delivery methods. for each bacterium was considered three treatments with different delivery methods. in first treatment, fish larvae were exposed to each bacterium through feeding them with bacter...

Interactions between bacteria which constitute the microflora of the digestive tract may be antagonistic or synergic. Certain bacteria can form a barrier to prevent colonisation of the gut by bacteria of other species or other strains of the same species. This review of current research refers to experiments on gnotoxenic animals, with mention of Escherichia coli and species of Clostr idium, La...
