This study provides crucial insights into the growth performance of Large White Yorkshire (LWY) pigs in the North-Eastern Agro-Climatic Zone of Tamil Nadu, which is essential for optimizing breeding and management practices. Growth performance data were collected over six years at the Pig Breeding Unit, Post Graduate Research Institute in Animal Sciences (PGRIAS), Kattupakkam. Information on pedigree, sex, growth performance, and disposal weights from 2011 to 2016 was utilized for this study. Statistical analyses were conducted using SPSS to determine the Absolute Growth Rate (AGR). The overall AGR measures for the age intervals from birth to 56 days, 56 to 120 days, 120 to 180 days, and 180 to 240 days were 118.77 ± 0.75 g/day, 268.80 ± 2.24 g/day, 270.93 ± 2.75 g/day, and 385.98 ± 7.19 g/day, respectively. The maximum AGR (412.57 ± 9.92 g/day) was found during the post-weaning growth period, while the minimum AGR (114.87 ± 1.73 g/day) occurred during the pre-weaning growth period. These insights can lead to better resource allocation, improved animal welfare, and increased economic returns in pig farming.
