Effect of hormone administration during peripartum period in crossbred sows

Abstract

Efficacy of PGFp and/ or oxytoqn was evaluated in four groups of sows (n=80) PGF 2a 5mg I/ m
on day 111 (group I), PG on day 111 and oxytocin20 IU 1/m after the birth offirstpiglet (group II), PG
after the birth of first piglet (group III) and oxytocin after the birth of first piglet (group IV) along with
suitable controls (group V and VI). The induction interval ranged from 26.85±0.52 to 28.16± 0.43
hours in group I and II, respectively. Duration of second stage of farrowing in all the four treatment
groups was less than three hours, whereas, it was more than four and half hours in control groups.
The overall piglet interval in this study varied from 6.57±0.41 to 7.92±0.92 minutes.
