The effect of vitamin D3 on laying hens

When raising laying hens, it's essential to not only meet their protein, carbohydrate, and mineral requirements but also ensure adequate vitamin D intake, particularly vitamin D3. This nutrient plays a crucial role in egg formation and overall reproductive performance. During the peak egg-laying season, sufficient vitamin D3 helps maximize the hen’s productivity, leading to more eggs and larger-sized eggs. In contrast, during the off-season—especially in winter—vitamin D3 can help maintain or even improve egg production, which is vital for maximizing income and enhancing the profitability of poultry farming. To ensure hens receive enough vitamin D3, there are several effective methods. First, you can include animal-based feeds such as small fish, shrimp, fish meal, blood meal, silkworm pupae, and insects in their diet, as these are naturally rich in vitamin D3. Second, offering green, leafy vegetables like tender grass, eucalyptus leaves, and carrots can also contribute to their vitamin D3 intake. Third, allowing hens to bask in natural sunlight, especially during winter, is highly beneficial. If they are kept indoors, artificial ultraviolet light can be used to support vitamin D3 synthesis. Lastly, for hens that have no access to sunlight, adding a vitamin D3 supplement or a multivitamin blend specifically formulated for poultry to their feed is a practical solution. By maintaining proper vitamin D3 levels, you not only improve the health and productivity of your flock but also ensure better economic returns from your poultry operation.

Co Extruded Wear Resistant Layer Composite Pipe

Co-extrusion polyolefin elastomers (POE) abrasion resistant inner layer plastic composite pipes is characterised by taking co-extrusion thermoplastic polyolefin elastomers as the abrasion resistant inner layer, using a combination of steel wires (or glass fiber) reinforcements and high-density polyethylene. In addition to good workability and physical and mechanical properties as HDPE pipes, such pipes have good wear resisting performance. Co-extrusion abrasion resistant composite pipeline is a kind of anti-abrasion pipe with high cost-effective performance.
