“…However, negative values for Parts a and b are not biologically acceptable. The lag time in the study of Wang et al [ 31 ] varied between −0.14 and 0.75 (h), which is consistent with our research. The calculated fermentation rate constant (c) in the study of Eseceli et al [ 32 ] was parallel with that in our study.…”

The modeling process has a wide range of applications in animal nutrition. The purpose of this work is to determine whether particle swarm optimization (PSO) could be used to explain the fermentation curves of some legume forages. The model suited the fermentation data with minor statistical differences (R2 > 0.98). In addition, reducing the number of iterations enhanced this method’s benefits. Only Models I and II could successfully fit the fermentability data (R2 > 0.98) in the vetch and white clover fermentation curve because the negative parameters (calculated in Models III and IV) were not biologically acceptable. Model IV could only fit the alfalfa fermentation curve, which had higher R values and demonstrated the model’s dependability. In conclusion, it is advised to use PSO to match the fermentation curves. By examining the fermentation curves of feed materials, animal nutritionists can obtain a broader view of what ruminants require in terms of nutrition.

“…This result was in the optimum range between 3.57-7.14 mM, hence it was expected to promote ruminal microbial biosynthesis. Higher NH 3 concentration reflects more protein decomposition during in vitro fermentation, and this is associated with higher CP content (Wang et al 2021). The different N-NH 3 derived in this research tended to be initiated by the amount of feedstuff crude fiber, as well as protein solubility and degradation rate.…”

Background: Optimum productivity of beef cattle is achieved with adequate feed supply, both in quality and quantity. Consumption of local feedstuff Neptunia plena L. Benth and Leersia hexandra Swartz as a ration by the animal subject is expected to promote cost efficiency and production, as well as provide essential nutrition needs. Therefore, this research aimed to evaluate dry matter digestibility (DMD), organic matter digestibility (OMD), N-NH3 production, and volatile fatty acid (VFA) in beef cattle. Methods: Feed and rumen inoculum samples were prepared and analyzed for their proximate contents. There were five treatment groups based on the diet received by beef cattle. In vitro approaches were used to determine the DMD, OMD, N-NH3 production, and VFA in beef cattle. The research was conducted in the Laboratory of Feed Nutrient Science, Faculty of Animal Husbandry and Agriculture, Diponegoro University, Semarang. The data were analyzed using ANOVA at a significance level of 95%, and a Duncan Multiple Range Test. Results: The results showed that the highest DMD (P<0.05) was derived from T5 (56.47%), followed by T4 (56.45%) and T3 (55.90%). T5=62.40% significantly (P<0.05) generated the highest OMD followed by T4=61.95% and T3=60.82%. This treatment had the highest N-NH3 value, namely 5.02 mM, compared with T3=4.55 mM, T4=4.50 mM, T2=4.22 mM, and T1=3.99 mM. Furthermore, T5 had the highest VFA (P<0.05) compared with T4, T3, T2, and T1 with the value of 150.5, 133.0, 130.5, 130.0, and 123.5 mM, respectively. Conclusions: The local feedstuff-based ration contributed to beef cattle production.

Background: Consumption of local feedstuff Neptunia plena L. Benth and Leersia hexandra Swartz as a ration by the animal subject is expected to promote cost efficiency and production, as well as provide essential nutrition needs. Therefore, this study aimed to evaluate dry matter digestibility (DMD), organic matter digestibility (OMD), ammonia (NH3) production, and volatile fatty acid (VFA) in beef cattle. Methods: Feed and rumen inoculum samples were prepared and analyzed for their proximate contents. There were five treatment groups based on the diet received by beef cattle, namely: T1 (Leersia hexandra Swartz 100 %); T2 (Neptunia plena L. Benth 100%); T3 (Leersia hexandra Swartz 15% + (Neptunia plena L. Benth 15% + 70 % Other Feedstuffs); T4 (Leersia hexandra Swartz 20% + (Neptunia plena L. Benth 20% + 60% Other Feedstuffs); T5 (Leersia hexandra Swartz 25% + (Neptunia plena L. Benth 25% + 50% Other Feedstuffs). In vitro approaches were used to determine the DMD, OMD, NH3 production, and VFA in beef cattle. The data were analyzed using ANOVA at a significance level of 95%, and a Duncan Multiple Range Test. Results: The results showed that the highest DMD (P<0.05) was derived from T 5 (56.47%), followed by T 4 (56.45%) and T 3 (55.90%).
