Using climatic data from 1991 to 2016 recorded at Avikanagar, wind chill index (WCI) was calculated for each day during winter (December–February) coinciding with major lambing season. The WCI (kcal/m2/h) was categorized as no chill ( 400.1 kcal/m2/h) since December 2003. The overall proportion of neonatal death ranged from 2.10% (WCI < 300 kcal/ m2/h) to 69.34% (WCI > 400.1 kcal/m2/h). The climatic data showed that out of total days, majority of days (64.99%) covered were of high to extreme chill in nature (WCI > 400.1 kcal/m2/h). The daily rate of neonatal mortality found to possess a positive and linear relation with WCI and ranged from 0.25 lamb death/day (WCI < 300 kcal/m2/h) to 0.46 lamb death/day (WCI > 450.1 kcal/m2/h). The entities responsible for exposure-inanition syndrome (EIS, debility, exposure, inanition) had positive relation with WCI. The contribution of EIS in overall neonatal mortality ranged from 29.08 (WCI 300.1–350.0 kcal/m2/h) to 42.00% (WCI > 450.1 kcal/m2/h). The analysis suggested requirement of proper shelter management for neonatal lambs during extreme climate. Not Available |
