“…In this study, the NDFD and ADFD were in the range reported by Hambakodu et al [18], i.e., 23.73 to 70.34% and 13.84 to 58.91%, respectively. The NDFD has a negative correlation with the lignin content of the fibre source [19]. The high NDFD can be caused by low lignin content and also affects the HSD.…”

Information on dairy fibre feed digestibility is important in ration formulation to better predict dairy cattle performance. However, its measurement takes time. Near-infrared reflectance spectroscopy (NIRS) is a rapid, precise, and cost-effective method to predict nutrient value, such as chemical content and digestibility of feedstuffs. This study aims to develop a database for an in vitro digestibility prediction model using NIRS, including dry matter digestibility (DMD), neutral and acid detergent fibre digestibility (NDFD and ADFD), and hemicellulose digestibility (HSD). Eighty dietary fibre feeds consisting of Napier grass, natural grass, rice straw, corn stover, and corn-husk were collected from four dairy farming areas in West Java (Cibungbulang District of Bogor Regency, Parung Kuda District of Sukabumi Regency, Pangalengan District of Bandung Regency, and Lembang District of West Bandung Regency). The spectrum for each sample was collected thrice using NIRSflex 500, which was automatically separated by 2/3 for calibration and 1/3 for validation. External validation was conducted by measuring 20 independent samples. Calibration and validation models were carried out by NIRCal V5.6 using the partial least squares (PLS) regression. The results showed that all parameters produce r2 > 0.5 except for ADFD. Relative prediction deviation (RPD) > 1.5 was only found in hemicellulose digestibility prediction. RPL (SEP/SEL) <1.0 were found in DMD and hemicellulose digestibility. It is concluded that hemicellulose digestibility can be predicted using NIRS accurately while other parameters need improvement.

“…The digestibility of NDF is higher than the digestibility of ADF because the NDF fraction still contains nutrients that are easily utilized by rumen microbes such as hemicellulose and cell wall proteins, while ADF contains many fractions that are difficult to digest, namely lignin and silica (Jamarun et al, 2017b); (Pazla and Jamarun 2021a). Similarly, Hambakodu et al (2020) highlighted that lignin levels have a negative correlation with ADF digestibility. The lower the lignin content, the higher the digestibility of ADF.…”

This study aims to obtain the best lignin content, ligninase enzyme activity and in vitro digestibility value of fermented sugarcane shoots using Pleurotus ostreatus and Aspergillus oryzae at different fermentation times. The research process is divided into 2 stages. Stage 1 treatment samples include A1B1 = Sugarcane shoots fermented with Pleurotus ostreatus for 14 days; A1B2 = Sugarcane shoots fermented with Pleurotus ostreatus for 21 days; A1B3 = Sugarcane shoots fermented with Pleurotus ostreatus for 28 days; A2B1 = Sugarcane shoots fermented with Aspergillus oryzae for 14 days; A2B2 = Sugarcane shoots fermented with Aspergillus oryzae for 21 days; A2B3 = Sugarcane shoots fermented with Aspergillus oryzae for 28 days. The design used is a completely randomized design with a factorial pattern. Stage 2 treatment samples cover A = Sugarcane shoots fermented with Pleorotus ostreatus for 21 days; B = Sugarcane shoots fermented with Pleorotus ostreatus for 28 days; C = Sugarcane shoots fermented with Aspergillus oryzae for 21 days; D = Fermented sugarcane shoots with Aspergillus oryzae for 28 days. The design used was a randomized block design. The results showed that there was no interaction between the type of mold and the fermentation time on the lignin content (P>0.05), but there was an interaction with the enzyme activity of Laccase, LiP and MnP (P<0.05). Also, there were significant differences in the digestibility of protein, cellulose, hemicellulose, VFA and NH3 (P<005), however the digestibility of DM, OM, ADF, NDF and rumen fluid pH had no significant difference (P>0.05). It was concluded that sugarcane shoots fermented with Pleurotus ostreatus mold for 28 days got the best results with the value as follow, lignin content (11.55%), CP digestibility (57.90%), cellulose digestibility (50.25%), Hemicellulose digestibility (62.65%), Laccase enzyme activity (2.68 U/mL), LiP enzyme activity (19.44 U/mL), VFA (111.67 mM) and NH3 (10.48 mg/100 mL).

“…Kecernaan pakan dalam rumen dipengaruhi oleh kandungan lignin pakan, lignin yang ada dalam pakan menghambat kerja mikroorganisme rumen dalam mencerna pakan. Kandungan lignin yang rendah dalam pakan maka miroba rumen dengan mudah mencerna pakan hijauan tropis (Hambakodu et al, 2020). Kandungan nutrien rumput alam serta kecernaan nutrien masingmasing rumput alam yang tumbuh di lahan perkebunan dan padang penggembalaan perlu dievaluasi karena datanya masih terbatas.…”

Rumput alam di padang penggembalaan kecamatan Pandawai kabupaten Sumba Timur perlu didata nilai nutrisi dan kecernaannya karena memiliki jenis yang beragam dan merupakan pakan utama yang dikonsumsi oleh ternak ruminansia. Penelitian ini bertujuan untuk mengetahui nilai nutrisi dan kecernaan in vitro rumput alam dari lahan perkebunan dan padang penggembalaan. Evaluasi nilai nutrisi menggunakan uji proksimat dan kecernaan dilakukan secara in vitro menggunakan cairan rumen sapi Bali. Penelitian menggunakan metode survei, rumput dari lahan perkebunan adalah Cynodon dactylon (kandaung hondu karambo), Digitaria ciliaris (kandaung mbata kambaku), Cynodon dactylon (L) Pers. (kandaung hira panggu), Panicum maximum (ndaica), Echinochloa cruss-galli (uhu randu), sedangkan rumput dari padang penggembalaan adalah Heteropogon insignis (mbelar penji), Sorghum nitidum (moru kapuka), Brachiaria decumbes (wolu kamemu), Ischaemun timorense (kahanga keri), Brachiaria humidcola (bara minah). Hasil penelitian rumput alam dari lahan perkebunan memiliki nilai nutrisi dan kecernaan in vitro yang lebih tinggi dibandingkan rumput alam dari padang penggembalaan. Rumput alam Cynodon dactylon (L) Pers, Echinochloa cruss-galli, Cynodon dactylon, Panicum maximum, Digitaria ciliaris memiliki nilai nutrisi dan kecernaan bahan kering dan bahan organik yang unggul.
