dc.description.abstractAn 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, - without wallow and sprinkler, Tj - 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, minimum temperature 22.8 to 26.1°C, mean temperature - 27.4°C to 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 higher range of temperature was sufficient to cause stress on the performance of the grower pigs as per the literatures. The treatment (TJ without wallow and sprinkler varies significantly (P<0.05) in the body temperature, respiration rate, cardiac rate both in the forenoon and afternoon from the Tj, T3 and T4 gramps, i.e., T^ has shown more of physiological stress reaction than other treatment groups. T, was found to be more comfortable than T^. and T3 were having no significant difference except in afternoon body temperature 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 T^, 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 T^ 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 T^, Tj, Tj and T^ were 5.08 ± 0.60, 4.97 ± 0.54, 5.28 ± 0.56 and 5.17 ± 0.60 and 339 ± 39.9, 330.9 ± 36.1, 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 production than T^, T^ and Tj. The conversion efficiency of T^, T^, T3 and T^ 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.en_US
