Mondal SK, De UK, Das GK, Powde AM, Verma AK., Mortality patterns of crossbred pigs in an industrial setting, Onl J Vet Res., 26 (2):124-129, 2022. We report mortality patterns and effects of age in 771/6330 crossbred landrace pig with 62.5-81.3% inheritance under intense production in tropical climates over 10 years. To determine mortality(%) patterns number of pigs dead was compared to those alive at different ages and years. Pigs were fed 35% maize, 47 wheat bran, 10% soya bean, 6% fish meal, 1.5% minerals and salt 0.5% salt, weaned at 45 days. Results revealed overall mortality of 12% with average pre-weaning mortality in last 10 years averaging 23%. Most (22%) occurred in 0-15 day piglets whereas lowest death (1.3%) in those 30-45 days old. Between 46-240 days mortality was 3.9% and after 2.6 %. Mortality was due to 2.8% digestive disorders, 2.4% hypoglycemia and poor condition, 1.2% trauma and 1% respiratory disorders
