Commercial poultry farming has grown considerably in recent years. This study aims to analyse its protein supply and identify potential for optimising phosphorus utilisation and feed efficiency.
Standard values for livestock feed intake and excretion are essential for proper farm fertilisation planning and assessment of the farm’s nutrient balance. Agroscope adjusted the standard values for sheep with the aim of improving nutrient-flow assessment.
The influence of horn status and the genetic variant of the (A1/A2) β-Casein milk protein on milk quality and digestion is the subject of much debate. This study shows that the milk of cows with a genetic difference in β-Casein is digested slightly differently in the human stomach, but that horn status has no effect in this regard.
