The effect of diet on the milk quality of organic dairy cows Organic Eprints
Weller, Richard; Davies, Robert.
This report was presented at the UK Organic Research 2002 Conference. Changes in milk quality were evaluated with spring-calving dairy cows and heifers fed organic diets and different levels of concentrates during early lactation. The diets were based on ad libitum forage and either 2 kg of concentrates/day (Diet 1) or concentrates fed according to milk yield up to a maximum of 7 kg/day (Diet 2). Average milk yields during the study for the cows and heifers were 23.1 and 20.1 kg/day (Diet 1) and 25.8 and 24.0 kg/day (Diet 2), respectively. The highest number of samples with a fat to protein ratio of 1.4 or > were found in samples collected from cows and heifers fed Diet 1 (20.9 and 50.0%). The lowest milk protein value of 2.86% was recorded from the...
