Application of the UFL/PDI nutritional system in feeding dairy cattle in Vietnam Date: 23/08/2007
A feeding trial was conducted to determine responses of milking cows to diets formulated according to the UFL/PDI nutritional system as compared to the nutritional system currently used in Vietnam based on metabolizable energy and crude protein (ME/CP). A total of 24 crossbred milking cows (F1 and F2) were divided into 2 groups to be fed on diets formulated according to the two systems for 3 months.
Results showed that feeding according to the UFL/PDI system brought about better milk yield, milk quality, body condition, feed conversion, and thus reduced feed cost per kg milk produced. It is therefore recommended that the current nutrional system in Vietnam be replaced with a modern system like the UFL/PDI system.
