[Induction of labor and its synchronization in hogs]

Area of Science:

• Veterinary Medicine
• Animal Reproduction
• Swine Production

Context:

• Farrowing synchronization is crucial for efficient management in large-scale swine operations.
• Induction of parturition can optimize resource allocation and piglet care.

Purpose:

• To evaluate the efficacy of Cloprostenol, a prostaglandin F2alpha analogue, for synchronizing farrowing in sows.
• To determine the time sequence and distribution of parturitions following Cloprostenol administration.

Summary:

• Administration of 175 micrograms of Cloprostenol to 147 sows resulted in synchronized farrowing.
• 93.7% of parturitions occurred between 14 and 39 hours post-administration.
• The peak farrowing time was observed between 24 and 27 hours (31.2% of cases).

Impact:

• Establishes a predictable farrowing schedule, facilitating improved herd management and labor organization.
• Provides valuable data for swine producers aiming to enhance operational efficiency through controlled farrowing.
• Supports the implementation of advanced reproductive management strategies in commercial piggeries.
