针对生猪不同生川百合长阶段 采用不同的颗粒尺寸

GLOBAL - Particle size, depending on the phase of production, can be 扫把竹managed to maximise nutrient digestibility or to maximise longevity. Re沼兰search has shown that for every 100 micron reduction in grain particle 香附米size, feed efficiency improves 1.0 to 1.2 per cent.Practical particle size recommendations are generally coarser for boars, gilt development, and gestation and finer for lactation, nursery, and finishing.

根据生产阶段制定不同的谷物颗粒尺寸可以设法使营养物质利用率最大化或生猪寿命最长化。研究表明谷物颗粒尺寸每缩小100微米，饲料转化效率提高1%到1.2%。推荐的谷物实际颗粒尺寸通常对公猪、发育与妊娠阶段的小母猪是不细化的，哺乳期、幼年期和育肥期的猪需要加工精细的谷物颗粒。
