Maintaining a consistent flow of good quality weaned pigs should be the
\nprincipal goal of a commercial swine operation, and to achieve this, producers
\nmust consistently meet weekly breeding targets. PG600 (400 IU eCG and
\n200 IU hCG; Intervet, USA, De Soto, KS) has been proven to induce a
\nsynchronized estrus in weaned sows. The primary objective of this study was
\nto determine effects of PG600 treatment at weaning on the percentage of
\nsows bred and subsequent litter sizes.
\nPrimiparous crossbred (PIC C22 and C29) sows from a 5,000 sow commercial
\nfarrow-to-wean facility were initially allocated to experiment by farrow weight
\nand genetics to 1 of 2 treatments: 1) PG: PG600 (n = 189) administered
\nintramuscularly in the sow\u2019s neck on the morning of weaning or 2) CON (n =
\n218): no treatment at weaning. Sows were bred according to herd protocol,
\ndepending on the day estrous was first detected. It was found that although the performance of PG and CON were similar in the
\ncurrent study, the advantage PG600 at weaning was realized in a tighter and
\nmore synchronous breeding \u201cweek\u201d of 2-3 days, which in turn, focuses heat
\nstimulation, heat detection and breeding into a narrower time window resulting
\nin a decrease in the spread of time at farrowing of the subsequent litter and
\nthus age at weaning.<\/p>\n","protected":false},"excerpt":{"rendered":"
