- Abstract
The study was conducted to analyse the micro-climatic variables and the performance of Large White Yorkshire sows in three different farrowing housing systems, viz., conventional farrowing house with guard rail and one-third slatted floor (T1), farrowing house with guard rail and floor level ventilation (T2) and farrowing house with farrowing crates (T3) to find out the suitable one for tropical climates like Kerala. There were significant variations (P<0.05) in microclimatic variables of farrow ing houses among treatments. The mean forenoon rectal temperature (°C) was significantly (P<0.01) less in T3 (38.39) compared to T1 (38.53) and T2 (38.64), whereas sows in T3 (39.69) had significantly (P<0.01) higher afternoon rectal temperature than T1 (39.12) and T2 (39.12). There were significant (P<0.01) variations in respiratory rate among treatments, sows in T3 had higher respiratory rate than T2 followed by T1. The average daily feed intake of T1, T2 and T3 were 5.42, 5.55 and 5.68 kg, respectively without any significant difference among them. Body weight loss during lactation was measured as 18.30, 17.80 and 23.32 kg in T1, T2 and T3, respectively, which was significantly (P<0.05) higher in T3 compared to other two treatments. The results of present study reveals that the significantly (P<0.05) higher house temperature, rectal temperature and respiratory rate in the farrowing house with farrowing crates lead to expression of negative behaviour of overlying, biting, injuring, killing the piglets and hostile to attendant which will lead to higher piglet mortality compared to other two houses namely conventional farrowing house with guard rail and one-third slatted floor and farrowing house with guard rail and floor level ventilation. So the latter two farrowing housing systems are more suitable for tropical conditions like Kerala.
