Heat Stress Amelioration by Roof Insulation and Water Fogging on Growth Performance of Large White Yorkshire Pigs' During Summer Season

摘要

A study was conducted to assess the effect of heat stress amelioration practices such as roof insulation and water fogging on the growth performance of Large White Yorkshire grower pigs in summer season in TANUVAS farm.Forty numbers of grower pigs were assigned to five treatment groups randomly. It was observed that the groups maintained under insulated roofing with 10 and 5 minutes fogging had numerically heavier body weight (62.58±1.57 and 61.38±2.02 vs 57.74±1.59kg), significantly (P<0.05) higher average daily weight gain (480.80±11.66 and 470.24±17.30 vs 36.11±1.18 g/ day) and improved feed efficiency (3.78±0.09 and 3.85±0.14 vs 4.08±0.13) than the control.
