Tampilan Lemak Dan Solid Non Fat Pada Susu Sapi Perah Akibat Asupan Neutral Detergent Fiber Yang Berbeda (the Display of Fats and Solid Non Fat of Dairy Cows Aaffected by Neutral Detergent Fiber Intake of Different Rations)

Abstract

This study was aimed to assess the optimal ration of Neutral Detergent Fiber (NDF) content to improve the performance of milk fat and Solid Non Fat (SNF) milk of dairy cows. This research was conducted at the Regional Operational Unit Mulyorejo, Livestock Breeding Barukan village, Tengaran Sub District of Semarang Regency and Banyu Aji Cooperative, Sub District of Getasan, Semarang Regency from June 29 to July 31, 2014. Animal used as experimental materials were 12 Friesien Holstein dairy cows in second and third months of lactation with estimated body weight averaged at 408.5 ± 30.86 kg (Coefisien Variance (CV) = 10.68%) and milk production averaged of 9.3 ± 1.01 liters (CV = 14.33%). The experimental design used in this study was a completely randomized design for three treatments, i.e. T0 (NDF content of 61%), T1 (NDF content of 63%), and T2 (NDF content of 64%). The results showed that milk fat T1 (3.28%) affected with T0 (3.51%), but not affected (P>0.05) with T2 (3.45%). SNF content of T0 (7.31%) affected (P<0.05) less than T1 (7.83%) and T2 (7.75%). This study concluded that increasing NDF content to 63% in feed can improve SNF and milk fat content
