Nutritional factors affecting milk production, milk composition, milk urea nitrogen, and plasma urea nitrogen



Nutritional factors affecting milk production, milk composition, milk urea nitrogen, and plasma urea nitrogen



Special Circular Ohio Agricultural Research and Development Center ( 163): 65-71



12 Holstein dairy herds in Ohio were visited once, and 25% of the lactating cows in each herd were randomly selected for data collection. Blood and milk were sampled approximately 4 h postfeeding. Many of the feeds and feed mixtures used on the farms were sampled and analysed for chemical composition. Nutritional factors were found to be more important than genetics in accounting for variations in milk yield, milk composition, milk urea nitrogen, and plasma urea nitrogen values.
