Abstract

The metabolizable energy (ME) of tropical forages measured by in vivo method in ruminants had a high degree of accuracy but requires a long time and is expensive. One method that can be done is the ME estimation model. The objectives of the present study were carried out to investigate the relationship between tropical forage nutrient content and ME for ruminants as well as determine and validate a model for estimating ME of tropical forage based on nutrient content. A total of 26 forage samples consisting of 14 types of grass and 12 legumes were obtained after data pre-processing or data cleaning and data normalization. Forage samples will be grouped into 3, Grass + Legume (G+L=26), grass (R=14), and legume (L=12). The database used is Crude Protein (CP), Extract Ether (EE), Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), and hemicellulose as well as ME with in vivo experiments. The initial stage is preprocessing data. Nutrient content and ME were analyzed using Pearson Correlation and followed by multiple linear regression to determine the ME estimation model. However, validated used the mean absolute deviation (MAD), root means square error (RMSE), and mean absolute percentage error (MAPE). The results showed that there was a significant and highly significantly correlated between nutrient composition and ME in the Grass + Legume, Grass, and Legume groups so it could be used to determine ME. There are 9 regression equations with significance and have high R2 and after being validated with the lowest MAD, RMSE, and MAPE values, three regression equations are obtained with one each for each group Grass + Legume (G+L), Grass (R), and Legumes (L). It is concluded that the regression equation of ME of tropical forage is MER+L = 12.429 – 0.122 ADF for Grass + Legume, EMR = 15.609 – 0.115 NDF for Grass, and EML = 3.726 – 0.186 CP for Legume.

Abstract

Kesulitan penyediaan pakan hijauan pada pengembangan peternakan ruminansia dapat diatasi dengan penggunaan sorgum  karena  mampu menghemat biaya pakan akibat pemanenan yang dilakukan berkali kali pada satu periode penanaman. Penelitian bertujuan mengevaluasi nilai nutrien dan kecernaan sorgum samurai akibat waktu panen dan pupuk urea yang berbeda pada panen pertama. Rancangan penelitian yang digunakan yaitu RAL Pola Faktorial (3x3) dengan 4 ulangan. Faktor pertama adalah perlakuan usia potong 80, 85 dan 90 hari setelah tanam (HST) dan faktor kedua adalah perlakuan dosis pupuk urea terdiri dari 200, 300 dan 400 kg ha-1. Hasil penelitian menunjukkan terdapat interaksi (p<0.05) pada perlakuan protein kasar dan NDF, bahan kering dipengaruhi (p<0.05) usia potong serta ADF (p<0.05) dipengaruhi dosis pupuk urea. WSC dan GE tidak dipengaruhi (p>0.05) usia potong, dosis pupuk dan interaksinya. Selanjutnya KcBK dan KcBO juga tidak dipengaruhi (p>0.05) usia potong dan pemberian pupuk  Waktu panen sorgum samurai 1 usia potong 80 HST dan dosis pupuk urea 200 kg ha-1 menjadi pilihan peternak karena mampu menghasilkan pakan kaya nutrisi sebagai bahan baku pakan ternak ruminansia.

Abstract

Forage is the primary and cheapest source of fatty acids (FA), which includes conjugated linoleic acid (CLA), influencing milk FA. This study aimed to analyze the fermentation, digestibility, biohydrogenation, nutrient composition, and FA content of napier grass (NG) and king grass (KG). Grasses were collected from the Pangalengan (highland) and Dramaga (lowland) districts at three harvest ages (1, 1.5, and 2 months). The feed was then analyzed for nutrients and FA. An in vitro study was performed to analyze the concentrations of NH3, VFA, protozoa populations, and biohydrogenation. No significant differences were observed in protozoa, pH, total VFA, or FA biohydrogenation. NH3 ranged from 5.31 mM to 8.86 mM. Significant differences were found at different altitudes, with an interaction between grass type and harvest age and an interaction between the three factors. The highest NH3 concentration was found in rations containing highland NG at 1.5 months. The DMD value was 58.27%–64.39%, and OMD was 61.07%–67.18%. Different digestibility values were observed at different harvest ages, with an interaction between altitude and harvest age. This aligned with the CF, NDF, and lignin contents in grasses. The highest was at 1.5 months NG. Significant differences were observed in the relative proportions of propionic acids. The highest value was in the ration containing the 1.5-month highland NG. Rations containing KG yielded significantly higher amounts of the C18:0 and C18:1 trans. In conclusion, the 1.5-month highland NG is a potential ration for supporting healthier FA production in milk.

Abstract

Sorgum merupakan tanaman pakan dengan kemampuan adaptasi pada lingkungan yang memiliki suhu tinggi. Penelitian ini bertujuan untuk menilai karakteristik agronomis sorgum varietas Samurai 2 akibat perlakuan usia potong dan dosis pupuk urea yang berbeda pada setiap ratun. Penelitian ini menggunakan Rancangan Acak Lengkap Faktorial (3 x 3) dengan 4 ulangan. Faktor pertama adalah umur panen 80, 90, dan 95 hari, dan faktor kedua adalah dosis pupuk urea 200, 300, dan 400 kg ha-1. Hasil karateristik agronomis menunjukkan bahwa pemanenan primer pada sorgum varietas Samurai 2 menunjukkan bahwa usia potong berpengaruh nyata terhadap jumlah anakan dan terdapat interkasi antara usia potong dan dosis pupuk urea terhadap jumlah daun. Pada ratun 1 menujukkan bahwa lebar daun dan jumlah daun dipengaruhi usia potong. Selanjutnya ratun I memperlihatkan terjadi perbedaan (P<0,05) pada panjang daun, lebar daun, jumlah daun dan jumlah anakan akibat usia potong. Secara umum bahwa perlakuan usia potong berpengaruh terhadap kondisi agronomis sorgum varietas Samurai 2 pada setiap ratun. Penelitian ini berimplikasi pada penyediaan pakan ruminansia yang berkualitas dan berkelanjutan.
