Maximizing Pigs' Farrowing Rates: Strategies in Heat Detection, Insemination, Semen Management, Feeding, and Selection

Maximizing Pigs' Farrowing Rates through Strategic Breeding Practices

Introduction:

Achieving optimal farrowing rates hinges on five pivotal areas, which collectively influence the success of breeding programs. These include heat detection, insemination techniques, semen management, feed management and body condition monitoring, selection of females, among others.

1. Heat Detection and Timing:

Understanding the biological rhythms governing a sow's estrous cycle is crucial for ensuring timely heat detection and mating opportunities. Producers are encouraged to recognize and mark sows with early signs of heat - swelling vulvas, mucous discharge, or ears that go up but lock upon mounting. It is essential not to miss the heat cycle by even a day as missing this critical window can significantly impact farrowing rates.

A practical approach involves getting gilts familiarized with boars before progressing towards heat detection exercises. Marking females showing initial signs of heat helps in predicting when breeding should occur, ensuring that pressure is applied firmly on their back to simulate a heavy boar presence or sitting on the sow if there's doubt about whether she's in heat.

2. Optimizing Insemination Process:

Breeding is akin to an art requiring finesse rather than just following a routine. The timing and process of insemination can significantly impact sperm mobility, thus influencing farrowing outcomes. To ensure optimal performance, it’s recommed to slow down the breeding process by elevating the of the catheter, allowing the semen dose more time for uptake without rushing.

While there might not be an exact timeline applicable across all gilts and females, certn sows might need a longer or shorter duration in the insemination process. The presence of semen backflow is indicative of poor technique, suggesting that adjustments are necessary to mntn the sperm's viability within the sow’s reproductive tract.

3. Semen Quality Management:

Semen quality plays an essential role in determining farrowing outcomes. Overordering can inadvertently lead to using older semen with potential detrimental effects on piglet survival rates and farrowing rate decline by 2 per day of storage beyond optimal conditions. Mntning semen age under ideal conditions 61°F - 64°F 16°C – 17.8°C ensures its potency.

It's crucial to unpack semen doses before refrigeration, store them loosely and horizontally to encourage r circulation, check refrigerator temperatures dly, and use insulated contners with gel packs for mntning temperature upon removal from storage for use. Special attention should be given to PCASI as it is more sensitive to fluctuations in temperature.

4. Feed Management for Optimal Body Condition:

Regular monitoring of sow body condition on a weekly basis ensures sows are neither under-nourished nor overfed, contributing positively to reproductive performance. Selection of gilts with good feet and leg structure, controlling body condition, and considering the use of copper sulfate to combat lameness issues can prevent involuntary culling.

Selecting gilts based on their foot health and size is essential as they enter breeding programs or gilt-development units where their future productivity deps significantly on proper management. Additionally, ensuring a balanced diet promotes puberty induction, and prioritizing gilt development aligns with focusing on the farm's future.

5. Strategic Culling and Replacement:

Proper culling strategies can impact farrowing rates by minimizing involuntary removal of sows and gilts that are not contributing to genetic gns or experiencing health issues. Selective breeding practices targeting lameness as a major cause for culling through foot structure, body condition control, and potentially introducing copper sulfate can reduce lameness.

Improving farrowing rates requires a holistic approach focusing on heat detection, optimal insemination techniques, semen management under favorable conditions, mntning appropriate feed intake, and strategic breeding decisions. While individual actions might appear minor in isolation, their collective impact significantly influences overall reproductive success.

By understanding the drivers of farrowing rate improvement and implementing these tactics, producers can achieve better performance outcomes for their livestock farming enterprise.
