Abstract
|
|
|
The effects of probiotic additions to feed and manure on temperature, humidity and carbon dioxide (CO2) emissions in
Hanwoo manure during summer (4 weeks) were evaluated. Fifteen Hanwoo (24-mo-old, 580 ± 20 kg) were housed in
individual pens (5 × 8 m) and randomly assigned to 1 of 3 treatments (n = 5 cattle per treatment). Hanwoo were fed
experimental rations as follows: control (10 kg roughage + 2 kg concentrate); T1 (10 kg roughage + 2 kg concentrate, 2%
probiotics on as-fed basis); and T2 (10 kg roughage + 2 kg concentrate, 2% probiotics on as-fed basis + 7 kg probiotics as
top-dressing on the surface of Hanwoo manure). In comparison to the control, the addition of probiotics to feed or feed and
manure had an effect (P < 0.05) on temperature and humidity over the 4 weeks, except for humidity at 0 weeks. The only
significant difference (P < 0.05) observed in CO2 emission was among all treatments at 3 and 4 weeks (but not at 0 through 2 weeks). These results indicated that use of probiotics as feed and manure additives did not have a significant effect on environmental parameters.
