“…Milk fatty acids are influenced by several factors such as ration [2], altitudes [8], milking time [9], forage quality [1] and fat supplementation [10]. Vegetable oil and plant fat are rich in PUFA [11], and their supplementation in dairy ration improves the milk fatty acid health index (MFAHI) and CLA [12]. However, it reduced feed fermentability and digestibility, especially fiber digestibility [11,13].…”

Supplementing dairy ration with Ca-soap vegetable oils rich in unsaturated fatty acid components increases the fatty acid profile and conjugated linoleic acid (CLA) levels in dairy milk, but it might reduce fermentability and digestibility. This study aimed to identify the effect of vegetable oil supplementation protected by Ca-soap on rumen fermentability and digestibility. Parameters observed included pH score, protozoa population, total VFA (volatile fatty acid), ammonia concentration, dry and organic matter digestibility (DMD and OMD), neutral and acid detergent fiber (NDF and ADF) digestibility. The results showed that increasing Ca-soap-protected vegetable oil levels in dairy ration significantly decreased (P<0.05) pH score, protozoa population, NH3 concentration, and digestibility. Oil type also significantly influenced all parameters except for microbial fermentation. The interaction effect of oil types and their levels were found in pH score, protozoa population, NH3 concentration, DMD, and fiber digestibility in ADF. Vegetable oils that influenced optimally were corn oil and canola oil. It is concluded that Ca-soap-protected vegetable oil supplementation in dairy ration should be less than 4%. It is suggested to study at the lower level. The type of oil used should consider its linoleic acid content and availability.

The amount of fibrous feed consumed by tropical cattle has an impact on the rumen’s liquid-to-solid ratio and feed passage rate. Feed fermentability and digestibility are influenced by ratio. Several in vitro procedures use varying liquid-to-solid ratios, which may or may not be applicable to the local situation. The purpose of this study is to compare the local cow rumen conditions with the liquid-to-solid ratio employed in the in vitro investigation. There were two experiments done for the study. First, the liquid-to-solid ratios in various in vitro experiments (Tilley and Terry = T1, Theodorou = T2, and Sutardi = T3) were compared to the circumstances in the rumen of local cattle (T0). Second, it was determined whether the various liquid-to-solid ratios used in various in vitro techniques were similar in terms of the feedstuffs’ fermentability (pH, NH3, VFA), digestibility (DMD and OMD), and fermentability (DMD and OMD) (F1 = Napier grass, F2 = maize, and F3 = soybean oil meal). The first experiment was fully utilized, and a 3 x 3 block factorial randomized design was used (second experiment). The liquid-to-solid ratio of T3 (1: 40) was discovered to be more comparable to the rumen state of nearby cattle (1:46). Different in vitro techniques had no discernible impact on pH, VFA, DMD, or OMD, but T3 produced more NH3 than T1 or T2 did. With F3 higher than F2 or F1, the major effects of fermentability and digestibility were discovered inside the feed. It is found that every feed studied produced higher NH3 concentrations thanks to the Sutardi method’s liquid-to-solid ratio, which is more akin to the rumen of local cattle. As a result, it is advised to evaluate feedstuff fermentability and digestibility for local cattle using the Sutardi method.

This study aimed to evaluate the microbial rumen population, fermentability, and digestibility of Moringa leaf supplementation in dairy cow ration using in vitro and to determine the optimal level of supplementation. The experiment consist of two steps with the first step was microbiology measurement used a Randomized Block Design with 5 treatments level of Moringa leaf extract (P0= control; P1= 5%, P2 = 10%, P3 =15%, P4 =20%) and the second step was in vitro fermentability and digestibility measurement used Randomized Block Design with 7 treatments level of Moringa leaf in dairy cow ration (R0 = control, R1 = R0 + 2.5% Moringa leaf, R2= R0 +5% Moringa leaf, R3 = R0 + 7.5% Moringa leaf, R4= R0+10% Moringa leaf, R5=R0+12.5% Moringa leaf, R6=R0+15% Moringa leaf) which grouped by rumen fluids. Data analysis used analysis of variance and continued with Duncan’s Multiple Range Test. The measured variable were microbial rumen population (bacteria and protozoa), fermentability (N-NH3, VFA), microbial protein synthesis, dry matter digestibility (DMD), and organic matter digestibility (DMO). The results showed Moringa leaf extract significantly decreased bacterial population (p<0.05), but there was no effect on the protozoa population. Moringa leaf supplementation did not affect N-NH3, DMD, and DMO, but significantly influenced VFA concentration and microbial protein synthesis (p<0.01). The higher Moringa leaf supplementation showed decreasing total VFA concentration, but was still within the normal range for rumen fermentation (102.29-126.69 mM). Moringa leaf supplementation showed a quadratic effect on microbial protein synthesis with an optimal supplementation level of 5%, but decreasing at a level of 7.5% still within in normal range. It can be concluded Moringa leaf can be supplemented up to 7.5% in dairy cow ration. Key words: digestibility, fermentability, in vitro, moringa leaf, dairy cow
