Research Note: A pilot study comparing White Leghorn and Isa Brown breeds under a free-range system on performance, egg quality and pasture characteristics

The aim of this study was to assess pasture growth, changes in botanical composition (BC), and the effects of pasture consumption on laying performance and egg quality in Isa Brown (IB) and White Leghorn (WL) hens. A total of thirty 18-week-old hens: 15 IB and 15 WL were used in this experiment whic...
