The national Profitable Lifetime Index (£PLI) is published by AHDB Dairy as part of its genetic evaluation service. The £PLI is a within-breed genetic ranking index developed for UK dairying conditions in consultation with industry partners and is expressed as a financial value. The £PLI is recommended for use by all-year-round calving UK farming operations . £PLI should be used as the initial screening tool in bull selection; then look within this group for the traits that most need improving in your herd. The £PLI value represents the additional profit a high £PLI bull is expected to return from each of its milking daughters over her lifetime compared with an average bull of £0 PLI. High £PLI will result in cows with improved udder conformation and feet, better calving performance and reduced costs because of improved milk quality and fertility.
