Nutrient Adequacy of Bali Cattle Fed Only Forage Derived From Palm Oil Plantation in Riau Indonesia

Abstract

An integrated system of cattle with palm oil plantations in Indonesia is potential in order to increase the cattle population in a sustainable manner. The study aims to assess the adequacy of Bali cow nutrient consumption only fed with forage derived from oil palm plantations. Five Bali cows pregnant about 5 months and 7 cows are not pregnant observed to find out their feed consumption. Cows were given only forage derived from oil palm plantations in Riau which contains dry matter (DM) 22.24%; crude protein (CP) 10.67%; crude fiber (SK) 36.85% and total digestible nutrients (TDN) 54.37%. Forage gave ad libitum. Observations consumption of cows in individual cages made for seven consecutive days, compared to the needs according to NRC (2003). The results showed that if only fed with forage of palm oil plantations did not meet the requirement of the cow; on the condition of pregnant, deficiency of DM as much as 2.76±0.20 kg/head/day (44.29±2.56 g/kgW^0,75/day; CP as much as 176.0±35.8 g/head/day (2.83±0.62 g/kgW^0,75/day); TDN as much as 1.39±0.20 kg/head/day (22.30±1.58g/kgW^0,75/day), while the not pregnant cows shortage DM as much as 2.01±0.41 kg/head/day (32.77±5.85 g/kgW^0,75/day); CP as much as 81.4±40.5 g/ head/day (1.30±0.65 g/ kgW^0,75/day); TDN as much as 1.03±0.22 kg/head/day (16.80±3.16 g/kgW^0,75/day). From the study it is concluded that consumption of Bali cow fed only forage from palm oil plantation can not meet their nutrient requirements; additional nutrients are needed, more on a pregnant cow than not pregnant.
