What is swine pig boar breeding reproductive technology? How to enhance boar pig swine breeding reproduction artificial insemination technology?  

I. Within the rapidly expanding swine industry, improving reproductive capacity is a core factor driving the sector's sustained progress and prosperity. As the key carriers for offspring production, the quality of boar husbandry and management directly determines herd genetic quality, reproductive efficiency, and farm profitability. Therefore, gaining a thorough understanding and mastery of scientific feeding and refined management methods for breeding boars has become essential for all swine practitioners. Let us now delve into the methods of breeding boar feeding and management.

II. During the critical mating period, breeding boars exhibit unique and complex nutritional requirements. At this stage, scientifically formulated feed ratios become pivotal in ensuring their reproductive performance is fully realized. Feed formulation for this stage: Corn 60%, Soybean meal 20%, Bran 10%, Hay powder 8.2%, Bone meal 1%, Salt 0.5%, Vinno High-Vitamin for Boars 0.1%, Vinno Multi-Mineral with Antimicrobial 0.1%, Vinno Probiotic Complex 0.1%.

III. During the non-breeding period, although reproductive demands are reduced, breeding boars must maintain optimal physical condition and basic physiological functions to prepare for subsequent breeding seasons. The feed formulation for this stage is slightly adjusted: Corn 51.6%, Rice Bran 24%, Wheat Bran 15%, Hay Powder 8.6%, Salt 0.5%, Vinno High-Vitamin for Boars 0.1%, Vinno Multi-Mineral 0.1%, Vinno Composite Probiotics 0.1%.

3. Temperature and humidity in the breeding boar environment are critical factors affecting growth, health, and reproductive performance. Generally, barn humidity should be strictly maintained between 65% and 75%. Temperature control requires comprehensive consideration of breed characteristics, age stage, seasonal variations, and external climate conditions. For instance, during hot summer months, effective cooling measures must be implemented to prevent heat stress in boars. Excessive heat can lead to reduced appetite, diminished semen quality, and decreased libido. Conversely, in cold winter periods, emphasis should be placed on insulation and warmth retention to ensure a comfortable environment within the pens. This prevents boars from expending excessive energy maintaining body temperature due to low ambient conditions, which could otherwise impair growth, development, and reproductive function.

4. During summer and autumn, high temperatures and humidity create a hot, humid environment that can adversely affect the physiological functions of breeding boars. Therefore, providing adequate shade is crucial. Farms should construct sturdy, well-ventilated shade structures, such as sunshades, to effectively block direct sunlight, lower pen temperatures, and create a relatively cool resting environment for boars. Additionally, daily bathing of breeding boars not only directly dissipates heat from their bodies but also cleanses skin impurities, reduces bacterial growth, and further alleviates heat stress. Simultaneously, prioritize managing air quality within pens by promptly venting toxic gases like ammonia and hydrogen sulfide. These harmful gases irritate the respiratory tract mucosa of boars, triggering respiratory diseases that compromise their health and reproductive capacity. Install ventilation equipment such as exhaust fans and air ducts to enhance air circulation, introduce fresh air, and ensure clean, oxygen-rich air quality within the pens.

5. Exercise Management: In daily husbandry, develop a scientifically sound exercise plan tailored to the boar's age, weight, and physical condition. Generally, ensure the boar receives adequate daily exercise, such as scheduled walks in an exercise yard. Exercise plays an irreplaceable role in maintaining normal metabolism, accelerating sperm production, improving sperm quality, enhancing sperm motility and fertilization capacity, thereby laying a solid foundation for breeding work.

6. During hot summers, high temperatures and humidity create favorable conditions for parasite proliferation and transmission, leading to increased surface parasite infestations in breeding pigs. A simple yet effective preventive measure is to thoroughly brush the pig's surface daily during peak heat periods. This comprehensive approach helps control parasite infections, ensuring boars maintain optimal health even in summer.

7. Scientific Disease Prevention: A scientific and rigorous approach is essential in disease prevention for breeding boars. Developing personalized prevention plans based on the boar's health status before mating is a critical step. Ensure timely vaccination to build sufficient immunity against pathogens. If antibody levels remain inadequate after multiple immunizations, consider isolating the boar for further diagnosis and treatment. For boars infected with severe diseases that fail to recover despite treatment, decisive measures for harmless disposal must be taken to prevent disease transmission and protect the health and safety of the entire herd. This is an essential step in ensuring the healthy development of the pig farming industry.
