N2  - An investigation was carried out to study the environment 
variables and the effect of modified housing conditions on the 
physiological norms and growth performance. during the dry 
season on the large white Yorkshire grower pigs. The modified 
housing include, Tl - without wallow and sprinkler, T2 - with 
wallow only, T3 - with sprinkler only and T4 - with wallow and 
sprinkler as the four treatment groups. 
The dry season (summer) characterised by higher ambient 
temperature (maximum temperature - 31.5° to 37°C, m: _ "_LllUm 
temperature 22.8 to 26.1 °C, mean temperature 27.4°C ._0 
31.3°C), comparatively lower relative humidity (mean RH 63.15 
to 75.68%) and wind speed (2.75 to 7.8 km/h). The b'~gher 
range of temperature was sufficient to cause stress OH the 
performance of the grower pigs as per the literatures. 
The treatment (T1) without wallow and sprinkler varies 
significantly (P<O.05) in the body temperature, respiration 
rate, cardiac rate both in the forenoon and afternoon from the 
T2, T3 and T4 groups, i. e., Tl has shown more of phys Lo Lc g i.ca L 
stress reaction than other treatment groups. T4 was fo' n~ to 
be mo re : comfortable than T1• T2 and T3 were hav:'. 9 no 
significant difference except in afternoon body temper ture 
and respiration rate. 
 
 
 

 
There were no statistically significant 
 


(P<0.05) 
 

 
difference between treatment groups in the fortnightly body 

weight gain from the first fortnight to upto twelfth 
 

 
'" 
fortnight. 
 

The twelfth fortnight body weight of the 
 

 
treatments Tl, T2, T3 and T4 were 70.833 ± 2.114, 69.333 ± 

5.816, 73.333 ± 5.681 and 71.667 ± 5.975. There were also no 

significant difference in the body length, chest girth and 
body height among the treatment groups in the fortnightly 

observations. Though Tl had shown significant (P<0.05) rise 
of physiological norms that had not reached upto the level of 

growth retardation. 

The overall fortnightly rate of gain (kg) and average 

daily gain (g) of the treatment groups of Tl, T2, T3 and T4 

were 5.08 ± 0.60, 4.97 ± 0.54, 5.28 ± 0.56 and 5.17 ± 0.60 and 
339 ± 39. 9 , 330 . 9 ± 36. I, 351 . 7 ± 37. 6 and 343. 9 ± 36. 0 . 

Under restricted feeding regime, T3 was having relatively 

better feed conversion efficiency and lower cost per kg of 
 

 
live weight pr'oduct.Lon than T4, Tl and T2• 
 


The convers ion 
 

 
	
efficiency of Tl, T2, T3 and T4 were 4.05, 4.15, 3.91 and 3.99 

and cost per kg of live weight production 36.16, 37.03, 35.05 

and 35.81. 

Based on the observations and the results suitable method 

of environment modification during the dry season for grower 
pigs can be recommended.
