| Abstrak/Abstract |
This research was intended to determine the effect of replacing forage with fermented completed feed or silage on milk production and fatty acids of Friesian Holstein Crossbred. This research used 6 of 3rd – 6th month lactating cows in average weight of 386.2±30.3 kg. The study consisted of 3 dietary treatments: concentrates + forages as usual (R1; control), concentrate + silage (R2), and fermented complete feed (R3). All dietary treatments were fed to the cows by following a switchback design that divided into three periods (P1, P2, and P3) that lasted for five weeks each, including a week of feed adaptation. The parameters observed were feed consumption, milk production, and milk quality, such as density, total solid non-fat, fat, and fatty acids. Results showed that replacing forages with fermented complete feed or silage did not affect milk production (12.2, 12.5, and 12.0 L/day)), density (1.023, 1.024, and 1.024), total solid non-fat (8.03, 8,50, and 7.37), fat (3.35, 3.37, and 4,92%), monounsaturated fatty acids (26.8, 29.7%, and 29.0%), and polyunsaturated fatty acids at (2.98, 3.60, and 2.82%, respectively). It can be concluded that silage and fermented completed feed can be used to substitute forage for Friesian Holstein Crossbred without negatively affect milk production and quality. |
