The experiment was carried out on Large White Yorkshire piglets housed in the modem pig breeding facility of the Livestock Farm Complex, Veterinary College and Research Institute, Orathanadu. Piglets from three separate sows of the same parity were regarded as three treatment groups (T1, T2, and T3), each group with eight piglets selected on the basis of weight and weaned at 28 days (T1), 42 days (T2), and 56 days (T3) of age, respectively, for the research work. The mean birth weights (kg) of three treatment groups T1, T2 and T3 were 1.51 ± 0.07, 1.40 ± 0.04 and 1.44 ± 0.05 respectively. There was no significant difference in birth weight between the treatment group of piglets. The data on weaning weight (kg) of three treatment groups T1 (28 days), T2 (42 days) and T3 (56 days) were 6.49 ± 0.22, 8.69 ± 0.26 and 11.26 ± 0.49 respectively. The mean body weight at 26th week of age for the three treatment groups T1, T2 and T3 were 61.42 ± 1.68, 58.82 ± 1.17 and 60.07 ± 2.00 respectively. There was no significant change in weekly body weight measured from the first to the 26th week of age between treatment groups.EnglishThesis
