| Indoor transmission of Ascaris suum partly depends on the physico-chemical conditions in bedding material. Temperature,pH, aqueous ammonia, moisture, occurrence and development of A. suum eggs were therefore compared in different areas(resting, intermediate and latrine) of two deep litter pens on an organic farm in four seasons. There was some variation, but mean ammonia levels were generally very low (1·0–2·6mM) and pH levels were moderate (8·04–8·88) in all three areas. Relatively, resting areas were characterized by overall moderate moisture (36%) and moderately high temperature (35·7 °C)levels. The area contained few eggs (50 eggs g−1 DM) of which 17% were viable, and though only 4% were larvated and 0·7% appeared infective, it was more than in the... |
