Precision livestock feeding by production profile (PP) classification

We previously developed a subjective classification system of production potential (PP) for incoming feeder calves and demonstrated its ability to predict feedlot growth performance. In this report the potential of precision livestock feeding (PLF) according to PP classification was investigated by feeding low-, medium and high production diets to the different PP classes in 2 randomised experiments. We demonstrated that the additional growth efficiency of PP 1 calves can be unlocked, with the potential improved economic returns.

此前，我们已开发出一套针对进厂饲料牛的产育潜力（PP）的主观分类体系，并证明了其预测育肥场生长性能的能力。在本报告中，通过向不同PP类别提供低、中、高产量饲料，在两项随机实验中探讨了根据PP分类进行精准畜牧饲养（PLF）的潜力。我们证实，PP1类牛的额外生长效率得以释放，从而具有提升潜在经济效益的潜力。
