During the period when hog prices are scraping the bottom, cutting costs and improving efficiency is the core strategy for breaking through. The foundation of pig farm profitability lies with the sows. Metrics such as PSY, number of live-born piglets, and post-weaning estrus rate are all hidden within inconspicuous daily details. Many farms fail to increase productivity not because of genetics or feed quality, but due to extensive management and neglected details. Focus on the following five critical points to steadily improve sow reproductive performance.
Detail One: Body Condition Scoring and Targeted Feeding 鈥?Rejecting a One-Size-Fits-All Approach
Body condition is a barometer of sow reproductive status. Being overweight or underweight both affect ovulation, embryo implantation, and postpartum lactation. Adhere to stage-specific P2 backfat measurement, with differentiated feeding for open sows, early gestation, late gestation, and lactation periods. Restrict feed in early gestation to prevent embryo death, moderately increase feed in late gestation to support fetal development; during lactation, focus on maximizing feed intake and strictly controlling excessive backfat loss to reduce problems of no estrus or repeated returns to estrus after weaning. Do not estimate body condition by eye; achieve precision feeding to keep sows in optimal condition.
Detail Two: Standardized Estrus Detection and Mating 鈥?Seizing the Optimal Breeding Window
Many cases of open sows and low productivity stem from inadequate estrus detection and mistimed mating. Insist on detecting estrus twice daily, using boar exposure combined with standing reflex assessment to determine the best mating time; standardize insemination procedures and ensure semen quality control. After mating, track return to estrus and conduct regular ultrasound pregnancy checks to identify open or aborted sows early, compress non-productive days, and reduce wasted feeding costs. For weaned sows, aim to achieve estrus and mating within 7 days to improve farrowing rate and live litter size.
Detail Three: Refined Farrowing Room Care 鈥?Reducing Postpartum Inflammation and Piglet Losses
The farrowing room is where sows suffer the highest losses. Implement all-in-all-out management, with cleaning and disinfection before entering the farrowing room; strictly control temperature and humidity, as sows are heat-sensitive while piglets are cold-sensitive, requiring zoned temperature control. Manage assisted farrowing properly, avoid unnecessary intervention, and reduce prolonged labor; emphasize postpartum anti-inflammatory treatment and uterine health care to lower the incidence of metritis, mastitis, and agalactia syndrome (MMA). At the same time, provide proper care for weak piglets and rational cross-fostering to improve weaning survival rate, ensuring sows wean smoothly and return to estrus quickly.
Detail Four: Environmental and Stress Management 鈥?Safeguarding Embryo Safety
For sows, especially in early gestation, stress is a hidden killer that increases miscarriages and weak piglets. Moving groups, mixing groups, injections, noise, and high temperatures are all strong stressors. Avoid moving or driving sows in the first 30 days after mating; implement cooling and heat stress prevention in summer, as heat stress directly causes reduced ovulation and increased stillbirths; keep pens dry and well-ventilated to reduce continuous damage from mold and harmful gases. Only a stable and comfortable environment can maintain embryo survival rate.
Detail Five: Dynamic Herd Optimization 鈥?Timely Replacement and Culling
Even the best management must be paired with a healthy and rational parity structure. Parities 3 to 6 represent the golden production period for sows, with stable litter sizes and good lactation performance; promptly cull sows that repeatedly fail to conceive, experience recurrent miscarriages, suffer from chronic inflammation that does not respond to treatment, consistently produce small litters, or have severe limb and hoof damage, to avoid continuous feed consumption and pen occupation. Reasonably control the annual replacement rate, continuously optimize the herd, and ensure the overall reproductive potential of the foundational sow herd is steadily realized.
In a low market, what truly matters is internal strength. There are no shortcuts in sow management, and no single trick guarantees success 鈥?the key lies in implementing details day after day. With the same sows and the same feed, refined management can create gaps in litter size, weaning survival rate, and annual litters per sow 鈥?this is the tangible profit margin in a bottom-market environment. Raising one sow well is like protecting one production line. By continuously refining the five aspects of body condition, mating, farrowing room care, stress management, and herd population, you can steadily improve farm production levels and calmly navigate cyclical fluctuations.
