Abstract
The purpose of the research work was to study the effect of early weaning
on production performance and behavioural changes in piglets. 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.
