Eliminating multiple sow lanes

Livestock experts agree that breeding herds need clear protocols for culling sows, and maintaining a balanced age distribution across parities is essential. The ideal percentage of sows in each parity should be around 17% for first-time sows, 16% for second, 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's an adequate supply of gilts, certain guidelines must 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 culled based solely on this criterion. Second, sows that fail to show estrus after hormonal treatment should be considered for removal. They should be monitored for up to 18 days post-weaning and 7 days after treatment. If they don’t come into heat, they are likely to have a farrowing rate below 50%, making them poor candidates for continued breeding. Additionally, sows that have produced six to seven litters should be evaluated for culling. These sows often experience reduced litter sizes, with more stillborn pigs and inconsistent piglet weights. Their weaker piglets are more prone to cold stress and disease. These sows also tend to have more teats, which can lead to difficulties in nursing and even suffocation of piglets. To reduce mobility issues, it's crucial to assess the leg and foot condition of sows when purchasing or selecting breeding stock. Using high-quality flooring can help prevent excessive weight gain and reduce lameness. Despite these precautions, some sows will still develop foot or leg problems, and those with chronic health issues are inevitably culled from the herd.

Excavator Components

This classification mainly includes the aluminum die casting Machinery Parts using in Excavator Components area.
From the part, we can easily find that the parts have a lot of features of big cavities, so the part will have big potential risk of mold release problem, if so, the part may happen to be deform, sticking to the mold etc, especially when the part sticking to the mold, if no clear in time, while next shot, the mold may be destroyed while clamping.
