Abstract
This research has been conducted to study the effect of superovulation prior to mating toward gilts reproduction
performance. Sixty gilts were divided into two treatments 1) gilts without superovulation and 2) gilts with
superovulation. Once the gilts shows a standing heat symptoms, the boar inserted into the pig pen to mat the gilts.
During the study, the pregnant gilts kept together in postal pens, then two weeks before farrowing each pregnant
gilts then placed in 2.5 x 3.5 m2 individual cages equipped with feeding and drinking devices. A Completely
Randomized Design (CRD) was used in the first phase of study, consisting of two treatments with 30 replicates
each, while analysis of data based on the mathematical model procedures, as follows: Yij = μ + α i + ε ij.
All data were then analysed using variance (Steel and Torrie, 1989).The results showed that the superovulation
treatments were highly significant affected (P <0.01) respectively against the daily sow ration consumption (DPRC)
4.87 ± 0.77 and 5.48 ± 0.45 kg, the sows milk production (SMP) per suckling 0.32 kg ± 0.10 and 0.39 ± 0.05
kg, the daily sows milk production (SMP) per day 6.23 ± 1.89 and 7.74 ± 1.00 kg, the sows milk production (SMP)
per lactation 305.54 ± 92.40 and 379.44 ± 11.08 kg
It is concluded that the superovulation treatment in the parent before mating can improve milk production of sow
which is described by the improvement of consumption of rations and the sow milk production.
