THE IMPACT OF BALANCED ENERGY AND PROTEIN SUPPLEMENTATION TO MILK PRODUCTION AND QUALITY IN EARLY LACTATING DAIRY COWS
Abstract: This research was
aimed to determine the impact of balanced energy and protein supplementation
with high rumen undegraded protein (HRUP) to milk production and quality in
early lactating dairy cows. Twelve early lactating Friesian Holstein cows were
divided into two groups (control and HRUP). Both control and HRUP group were
fed on a basal diet (forage to concentrate ratio was 60:40; DM basis), with
rumen undegraded protein (RUP) levels were 27.47% and 32.78% for control and
HRUP, respectively. The experimental diets were given to animals twice daily,
morning and afternoon. Water was given by ad libitum. The observed parameters
were nutrient intake, quantity and quality of milk production . Data were
examined using t-test. Results showed that feed intake, milk production and 4%
FCM, milk fat and lactose concentrations, and milk solid non-fat and total
solid concentrations were not differed significantly between control and HRUP
groups. However, milk protein concentration and production were differed
(P<0.05) between controls and HRUP groups. The balanced energy and protein
supplementation with HRUP in early lactating dairy cows could impact on milk
protein concentration and production.
