Porcine Fetal Growth: Days 70-115 – What Farmers Must Know
Efficient swine management hinges on a comprehensive understanding of porcine fetal development days 70 to 115. The Iowa Pork Producers Association (IPPA), a leading agricultural organization, recognizes this critical period as one where nutrient requirements for the sow are paramount to ensuring optimal piglet health. Sound nutritional strategies, often informed by tools like the NRC (Nutrient Requirements of Swine) guidelines, become absolutely crucial during this developmental phase. Furthermore, consulting with a veterinary practitioner is highly recommended as monitoring and management practices specifically targeting porcine fetal development days 70 to 115 can significantly impact farm profitability by reducing stillbirths and improving weaning weights.

Understanding Porcine Fetal Development: Days 70-115 for Optimal Farm Management
This article outline aims to provide farmers with critical information about porcine fetal development during days 70 to 115 of gestation. This period is particularly vital for ensuring healthy piglets and maximizing farm productivity.
Why Focus on Days 70-115?
Days 70-115 represent a crucial window in the pig’s pregnancy. This is when the majority of fetal growth and organ maturation occur. Any stressors or deficiencies during this phase can significantly impact piglet viability, birth weight, and overall health. Understanding the physiological processes taking place allows farmers to make informed management decisions.
Key Developmental Events
- Rapid Weight Gain: The fetus experiences exponential weight gain during this period. Nutritional demands on the sow increase significantly.
- Organ Maturation: Major organs, including the lungs, brain, and digestive system, undergo critical development and refinement.
- Skeletal Development: The skeletal system continues to ossify and strengthen, impacting piglet mobility and survival after birth.
- Immune System Development: The piglet’s immune system begins to develop, relying heavily on antibodies transferred from the sow.
Nutritional Requirements During Days 70-115
Proper nutrition for the sow is paramount during this period. Inadequate nutrition can lead to reduced piglet birth weight, increased stillbirth rates, and compromised piglet immune function.
Essential Nutrients and Their Impact
- Protein: Critical for fetal tissue growth and development. Ensure adequate protein levels in the sow’s diet, focusing on high-quality protein sources.
- Energy: Provides the necessary fuel for rapid fetal growth and development. Insufficient energy intake can lead to nutrient deficiencies.
- Vitamins: Vitamins A, D, and E are essential for skeletal development, immune function, and overall health. Consider supplementing the sow’s diet if necessary.
- Minerals: Calcium, phosphorus, and iron are crucial for bone development and blood production.
- Calcium & Phosphorus Ratio: Maintain a proper calcium-to-phosphorus ratio in the diet to prevent skeletal abnormalities.
- Water: Ensure access to fresh, clean water at all times. Dehydration can negatively impact nutrient absorption and fetal development.
Feeding Strategies
- Gradual Increase in Feed: Slowly increase the sow’s feed allowance during late gestation to meet the increasing nutritional demands of the developing fetuses.
- Monitor Body Condition: Regularly assess the sow’s body condition score to ensure she is neither overfed nor underfed.
- Feed Quality: Choose a high-quality gestation diet specifically formulated to meet the nutritional needs of pregnant sows.
Managing Environmental Stress
Stress can negatively impact porcine fetal development days 70 to 115. Maintaining a comfortable and stress-free environment for the sow is crucial.
Types of Environmental Stress
- Temperature Fluctuations: Extreme temperatures (both hot and cold) can cause stress and reduce nutrient intake.
- Poor Ventilation: Inadequate ventilation can lead to the build-up of harmful gases and increase the risk of respiratory infections.
- Overcrowding: Overcrowding can cause stress and increase the risk of injury and disease.
- Noise: Loud or sudden noises can startle the sows and lead to stress.
Mitigation Strategies
- Temperature Control: Maintain a consistent and comfortable temperature in the farrowing house. Use heating or cooling systems as needed.
- Proper Ventilation: Ensure adequate ventilation to remove harmful gases and maintain air quality.
- Adequate Space: Provide sufficient space for the sows to move around and rest comfortably.
- Minimize Disturbances: Reduce noise levels and minimize disturbances in the farrowing house.
Disease Prevention and Management
Disease can severely impact fetal development and lead to significant economic losses. Implementing effective biosecurity measures and proactively managing disease are essential.
Common Diseases Impacting Late Gestation
- Porcine Reproductive and Respiratory Syndrome (PRRS): Can cause abortion, stillbirth, and weak piglets.
- Porcine Parvovirus (PPV): Can cause reproductive failure and embryonic death.
- Leptospirosis: Can cause abortion, stillbirth, and weak piglets.
- Swine Influenza: Can cause fever, respiratory distress, and reduced appetite, impacting fetal development.
Preventative Measures
- Vaccination: Implement a vaccination program to protect sows against common reproductive diseases. Consult with a veterinarian to determine the appropriate vaccination schedule.
- Biosecurity: Maintain strict biosecurity protocols to prevent the introduction and spread of disease. This includes controlling access to the farm, disinfecting equipment, and quarantining new animals.
- Early Detection: Monitor sows for signs of illness and consult with a veterinarian immediately if any problems are detected.
Monitoring and Record Keeping
Regular monitoring of sows and meticulous record-keeping are essential for identifying potential problems and making informed management decisions.
Key Monitoring Points
- Sow Body Condition: Regularly assess the sow’s body condition score to ensure she is neither overfed nor underfed.
- Feed Intake: Monitor feed intake to ensure the sow is consuming adequate nutrients.
- Water Consumption: Monitor water consumption to ensure the sow is adequately hydrated.
- Fecal Consistency: Observe fecal consistency for any signs of digestive upset.
- Behavior: Monitor the sow’s behavior for any signs of stress, illness, or discomfort.
Importance of Record Keeping
- Track Sow Performance: Maintain records of sow performance, including breeding dates, feed intake, weight gain, and health status.
- Identify Trends: Use records to identify trends and patterns that may indicate potential problems.
- Evaluate Management Practices: Use records to evaluate the effectiveness of management practices and make adjustments as needed.
- Optimize Productivity: Accurate and comprehensive record keeping can help to optimize farm productivity and profitability.
Practical Tips for Farmers
- Consult with a Veterinarian: Develop a comprehensive health management plan with your veterinarian.
- Work with a Nutritionist: Work with a nutritionist to develop a feeding program that meets the specific needs of your sows.
- Invest in Training: Provide training to farm staff on proper animal handling, disease prevention, and monitoring techniques.
- Stay Informed: Keep up-to-date on the latest research and best practices in swine management.
