Description

A simple device was developed to automatically sample feces at certain time intervals, and the fluctuations with time in the amount of feces in 4 goats was analyzed using maximum entropy spectral analysis. The fluctuation with time in the amount of feces over time was larger for sorghum silage feeding than maize silage feeding. An obvious peak of spectral density at the frequency of 0.0848 (11.8h per cycle) was detected in the power spectral diagram for sorghum silage feeding. Furthermore, 2 peaks with a lower power density were also detected at lower frequencies of 0.0121 (82.6 h per cycle) and 0.0485 (20.6 h per cycle). In maize silage feeding, on the other hand, a maj or peak was detected at the frequency of 0.0364 (27.5 h per cycle), and lower peaks at 0.0121 and 0.0667 (15.0 h per cycle). Periodic fluctuations such as a daily circadian rhythm, a short-term fluctuation like a semidian rhythm and a long-term fluctuation with a frequency of 0.0121 (82.6h per cycle) were observed in both kinds of silage feeding.
