Eliminating multiple sow lanes

Livestock specialists generally agree that breeding herds should have clear protocols for culling sows, and maintaining a balanced age distribution across parities is essential for optimal productivity. The ideal proportion of sows in each parity is approximately 17% for first-litter sows, 16% for second-litter, 15% for third, 14% for fourth, 13% for fifth, 12% for sixth, 10% for seventh, and less than 4% for those beyond the eighth litter. When there are sufficient young gilts available, certain guidelines should be followed to determine which sows to remove at weaning. First, it's important to cull sows that have had two consecutive litters with low farrowing rates. However, first-time sows that are underweight, overfed during gestation, or lose too much weight during lactation, as well as those with poor weaning conditions, should not be included in this culling process. These factors can affect their long-term performance and should be considered carefully before making a decision. Second, sows that do not show estrus after hormonal treatment should be culled. After weaning, sows should be monitored for up to 18 days, and after hormone administration, they should be observed for seven days. If they fail to come into heat during this period, they are likely to have a farrowing rate below 50%, making them inefficient for breeding purposes. Additionally, sows that have already produced six to seven litters should be considered for removal. At this stage, they often experience a decline in litter size, particularly due to an increase in stillborn pigs. Their piglets may also be smaller and more inconsistent in size, leading to weaker piglets that are more prone to cold and disease. These sows tend to have larger teats, which can make nursing difficult and increase the risk of pig suffocation. Furthermore, their mobility may become impaired, increasing the likelihood of lameness and other health issues. To reduce the occurrence of movement-related problems, it’s crucial to assess the leg and hoof condition when selecting or purchasing sows. Using high-quality flooring in pens can help prevent excessive weight gain, which can worsen joint and hoof issues. Despite these precautions, some sows will still develop lameness or other health problems, and these cases must be addressed by culling to maintain herd efficiency and animal welfare.
