Abstract
Abstrack. Study to investigate the digestibility of feed NDF and ADF components in Timor deer (Cervus timporensis) and its daily activities (eating, drinking, resting, sleeping, and chewing activities) in Timor deer (Cervus timorensis) receiving an additional feed of oil palm meal at different levels was carried out in August - September 2019. This study used 4 Timor deer, aged about 1-2 years, with a body weight range of 25-30 kg.The research was designed experimentally using the Latin Square Design (RBSL) with 4 treatments and 4 replications. The treatments applied were BKS0 (oil palm meal 0% + rice bran 94.49% + urea 3.80% + premix 1.0 % + salt 1.0 %) BKS10 (palm oil meal 10 % + rice bran 84, 91 % + urea 3.08% + premix 1.0 % + salt 1.0 %), BKS20 (oil palm meal 20 % + rice bran 75.33 % + urea 2.67 % + premix 1.0 % + salt 1 0.0 %), and BKS30 (oil palm meal 30 % + rice bran 65.74% + 2.25% urea + Premix 1.0% + salt 1.0 %). Data collection of the daily activities Timor deer uses a camera closed-circuit television (CCTV) of the Xiaomi xiaofang type, the camera is placed at the front of the research cage which is connected to the cellphone and can store the recordings in a micro external memory so that it can be reviewed at any time. Results showed that the digestibility of NDF fiber components tended to be affected significantly by the treatment with an average digestibility value for the treatment BKS0 = 69.99%, BKS10 = 63.84%, BKS20 = 63.01%, and BKS30 = 63.23%. The digestibility of ADF was affected significantly by the treatment with an average digestibility values for the treatment BKS0 = 55.98%, BKS10 = 47.21%, BKS20 = 45.17%, and BKS30 = 48.06%. The daily activities of Timor deer was found to be as follows: BKS0 = resting 55.9%, eating 30.7%, chewing 8.78%, sleeping 4.26%, drinking 0.48%, BKS10 = resting 55.97%, eating 27.28%, chewing 9.3%, sleeping 7.22%, and drinking 0.41%, BKS20 = resting 48.05%, eating 29.3%, chewing 12.04%, sleeping 10.09%, and drinking 0.48%, and BKS30 = resting 52.35%, eating 27.67%, chewing 13.85%, sleeping 5.79%, and drinking 0.41%. Based on the results of the study, it was concluded that there was an effect on fiber digestibility on the lower fiber fraction content. The lower the fiber content, the better the quality of the feed because the feed is easy to digest. Daily activity of Timor deer which is given rations with different levels of oil palm meal with 12 hours of observation shows that resting activity is more dominant followed by eating, ruminating, sleeping and the least activity is drinking.
