Abstract

Objective: This study aimed to explore and understand the source of fiber feed that is commonly used, and analyze the activities of fiber feed provision in dairy farms during the dry season, and investigate the fiber feed supply chain.Methods: This research was conducted on rural dairy farms in the Sub-district of Lembang located in West Bandung District. The data was collected by adopting an interview method with 50 farmers implements a purposive sampling technique to gather information regarding the provision pattern, supply chain of respective fibre feed. Samples of fiber feed in the dairy farms were taken using a simple random sampling technique. The data acquired is analyzed using descriptive analysis; these data consist of nutrient content of the fiber feed, provision pattern during the dry season, and the supply chain map of those fiber feed provisions.Results: The result reveals that the fiber feed that has been given to the dairy cows was cultivated grass, natural grass, legumes, and plant residue that entirely supplied from neighborhood area (≤ 30 km), which has different nutrient content. There are 16 provision patterns of fibre feed in the dry season, the vast majority of provision pattern was the combination of foraging from the farmer’s land and feed purchasing. By referring to the RFV calculations, legumes and vegetable waste have good quality. The fibre feed supply chain is relatively short, which is about (1-4 actors) due to its freshness and required no processing.Conclusions: In conclusions, the fibre feed that has been given to the dairy cows was cultivated grass, natural grass, legumes, and plant residue. There are 16 provision patterns of fibre feed in the dry season. The fibre feed supply chain is relatively short.

Abstract

Tropical foliage is an alternative source for protein enrichment in the dairy ration. However, due to the expensive, laborious, and time-consuming data-gathering method, its degradability database for inclusion in ration formulation is still lacking. This study aims to estimate tropical foliage's in situ protein degradability (RDP) using chemical compositions, in vitro digestibilities, and near infrared reflectance spectroscopy (NIRS) methods. The study used one hundred ten tropical foliage samples and observed chemical composition, in vitro dry and organic matter digestibility, and in situ degradation characteristics variables. NIRS spectra were collected to calibrate and validate the in situ degradation characteristics. Correlations were made prior to regression analysis. The results showed that tropical foliage varied in ash (3.02%-18.3%), crude protein (CP) (11.6%-30.7%), crude fiber (CF) (10.2%-29.8%), neutral detergent fiber (NDF) (31.0%-58.2%), acid detergent fiber (ADF) (18.7%-44.1%), dry matter digestibility (DMD) (23.9%-73.2%), organic matter digestibility (OMD) (25.6%-73.9%), and in situ RDP (21.0%-75.4%). The foliage was highly degraded (RDP > 60%) except for Calliandra calothyrsus (59%). In situ RDP significantly correlated with ash, CP, CF, DMD, and OMD with coefficient correlations (r) of 0.43, 0.60, -0.33, 0.74, and 0.76, respectively. Estimation of RDP using chemical composition and in vitro digestibility followed the equation: RDP (%)= 0.69 + 2.122 CP (%) with R²= 0.41 (p<0.01) and RDP (%)= 0.162 ash + 1.270 CP -0.104 CF + 0.489 IVOMD, with R²= 0.68, p<0.01). Calibration of NIRS using in situ RDP resulted in a regression coefficient (R²) of 0.78. It is concluded that RDP tropical foliage can be estimated more accurately using NIRS compared to in vitro digestibility and chemical composition.

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

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.
