“…These data suggest that pH and moisture changes in litter have a profound effect upon fungi. Halbrook et al (1951) and Dennis et al (1975) but disagree with those of Bacon and Burdick (1977) who observed that neither pH nor moisture showed any effect on fungal population density. In reused litter (Table 6), mortality is correlated (P<.05) to week, mold count, and moisture.…”

Three of five houses on a commercial broiler farm were cleaned, and hardwood sawdust was spread to a depth of about 3 cm prior to the arrival of chicks. Hard or caked litter was removed from the remaining two houses, and litter was top dressed with about .25 cm of hardwood sawdust. Litter samples were collected weekly from each house. Moisture, pH, and mold counts were determined for each sample. No significant differences were detected in average bird weight, feed conversion, mortality, or condemnations. Litter moisture and pH values increased over the course of the experiment, whereas litter ash values showed no consistent trends. The highest mortality for birds on both litter types occurred in the first week of the experiment. However, the data suggest that when new litter is used for broilers, mortality is more evenly distributed over the grow-out period. (

“…Halbrook et al (1951) found a relationship between litter age and numbers of all classes of bacteria and fungi. They also found that litter used for 1 to 8 weeks contained 116 times more mold and 100 times more yeast than litter that was built-up for over 1 year.…”

The Relationship Between Yeast and Mold Populations in Litter of Broilers Fed Dietary Fungistatic Compounds

et al. 1982

Two experiments were conducted at two institutions, to study the effect of fungistatic compounds in broiler diets. Dietary fungistatics were sorbic acid, 400 ppmjsorbic and adipic acids, combination at 200 ppm each; gentian violet, 8 ppm and calcium propionate, 1000 ppm. Two levels of feed-moisture (12 and 14%) were used at one institution while two litter types (new and old) were used at the other. Microbiological analysis for yeast and mold populations were made immediately before birds were placed in pens and every 2 weeks thereafter for a period of 8 weeks.The addition of fungistatic compounds to broiler diets altered the growth patterns of yeast and mold in both old and new litters. Data also indicated a definite interception between yeast and mold growth rates in litters. Fungistatic compounds used in this study showed a more pronounced effect on the mold population than on the yeast population. Regardless of the litter type or the moisture content, a sharp reduction in the mold population accompanied by a sharp increase in the yeast count was observed at different time intervals during the study.
