Whole milk and at least one additional nutrient source are admixed to reach a target diet and the amount of each of the admixture components is calculated based on compositional analysis results of the available whole milk, known levels of nutrients in the additional nutrient source, and the dietary target(s) for the young animals. The compositional analysis and admixing may be performed at the location where the young animals are fed.全乳與至少一個額外養分來源被混摻,以達到目標飼糧以及混摻物組分的各者份量是基於可取得全乳的組成分析結果、在額外養分來源中的已知養分位準、與幼小動物用的(多個)飼糧目標來計算。該組成分析與混摻可在餵食該幼小動物的地點進行。
