“…Similarly, Piamphon et al [ 38 ] noted that hemoglobin and hematocrit were unaffected when feeding yeast-fermented Napier grass mixed with cassava root to beef cattle. In comparison to the previous findings, all of the hematological indices for ruminants remained within their respective ranges [ 17 , 39 , 40 ]. Based on these findings, it can be assumed the addition of YERSEK at any level to the diet of dairy cows is non-toxic.…”

The objective of the present study was to analyze the effects of yeast-fermented rubber seed kernels (YERSEK) on the feed intake, hematology, microbial protein synthesis, milk yield, and milk composition in dairy cows. Six crossbred Holstein Friesian (HF) × Thai lactating dairy cows with 110 ± 10 days in milk were randomly assigned to three different amounts of YERSEK at 0%, 10%, and 20% in a concentrate mixture using a 3 × 3 repeated Latin square design. Cows were fed with concentrate diets at a concentrate-to-milk yield ratio of 1:1.5, with rice straw fed ad libitum. The inclusion of YERSEK did not adversely affect feed intake, nutrient intake, or digestibility (p > 0.05), whereas ether extract intake and digestibility linearly increased in dairy cows receiving YERSEK (p < 0.01). Increasing YERSEK levels did not adversely affect blood urea nitrogen (BUN) levels, hematological parameters, or microbial protein synthesis (p > 0.05). Supplementation of YERSEK did not influence milk production, lactose, or protein levels (p > 0.05). However, milk fat and total solids decreased linearly (p < 0.05) with the addition of YERSEK. In conclusion, in a concentrate diet, YERSEK could be used as a protein source without negative effects on feed intake, digestibility, hematology, microbial protein synthesis, or milk yield. However, it reduced the milk fat and total solids of tropical lactating dairy cows.

“…Dietary regimens were based on YERSEK levels of 0%, 10%, and 20% in concentrate diets ( Table 1 ). Mid-lactation crossbred dairy cows were fed concentrate diets with a milk production ratio of 1:1.5 [ 16 , 17 , 18 ] and ad libitum rice straw as roughage. At 7:00 a.m. and 4:00 p.m. each day, diets were provided.…”

The aim of this study was to investigate the effect of Terminalia chebula meal (TCM) supplementation on digestibility, rumen fermentation, nitrogen utilization, and protozoal population in goats. Eight goats with an initial body weight (BW) of 13 ± 3.0 kg were randomly assigned according to a double 4 × 4 Latin square design to receive different levels of TCM supplementation at 0, 8, 16, and 24 g/kg of total dry matter (DM) intake, respectively. The goats were fed with concentrate diets at 13 g/kg BW, while rice straw was used as a roughage source, fed ad libitum. The results revealed that the feed intake and the apparent digestibility of DM, organic matter (OM), neutral detergent fiber (NDF), and acid detergent fiber (ADF) were similar among the treatments (p > 0.05). However, crude protein (CP) digestibility decreased significantly (p < 0.05) when supplemented with TCM at 24 g/kg of total DM intake (p < 0.05). The addition of TCM did not change the ruminal pH and blood urea nitrogen concentrations (p > 0.05), whereas the concentration of NH3-N at 4 h post feeding was reduced with the inclusion of TCM at 16 and 24 g/kg of total DM intake. The total numbers of bacteria were enhanced by the addition of TCM, while the protozoal population, in both entodiniomorph and holotrich, was reduced (p < 0.05). The supplementation of TCM did not change the concentration of total volatile fatty acids (TVFA), acetic acid, or butyric acid, while the propionic acid concentration at 4-h post feeding increased significantly, especially when supplemented at 16 g/kg of total DM intake (p < 0.05. In addition, urinary nitrogen (N) excretion decreased, while fecal N excretion, N absorption, N retention, and the proportion of N retention to N intake increased with the inclusion of TCM at all levels. In summary, the inclusion of TCM could improve rumen fermentation efficiency and N balance without having an adverse effect on feed intake, nutrient digestibility, and rumen ecology; however, the protozoal population decreased. Therefore, this study suggests that TCM (16 g/kg of total DM intake) could be used as a plant source for rumen enhancement in goats fed a diet based on rice straw without having an adverse effect on feed intake or nutrient digestion. However, further studies on the production of types of meat and milk that have a long-term feeding trial should be carried out.

“…Ruminal protozoal population at 2 h and 4 h after incubation with various doses of hog plum supplementation are shown in Table 3. Numerous tropical plants consisting great contents of saponins have become interesting choices for interrupting protozoa in the rumen (Gunun et al, 2019). At 2 h after incubation, there were no changed on protozoal counts (P>0.05), whereas the reduction of protozoal counts were found when added hog plum at 4 h after incubation (P<0.05).…”

“…Tropical plants consist of high contents of saponins which have become noticeable choices for prohibiting protozoa in the rumen (Gunun et al, 2019). These possibly be that these compounds may disturb the activity of ruminal protozoa, likely by attaching the proteins and enzymes of the protozoal membranes (Hristov et al, 2013).…”

The research was to elucidate the influences of dietary hog plum supplementation on nutrient digestibility, fermentation characteristics, protozoal population and kinetics of gas production. Completely randomized design (CRD) was used and the treatments were 6 levels of hog plum supplementation at 0, 0.5, 1.0, 1.5, 2.0 and 2.5 mg DM. Hog plum consisted of CP at 5.6% DM and saponins was found about 9.4%. Supplementation of hog plum did not alter gas production from the soluble fractions (a), gas production from the insoluble fraction (b) and the potential extent of gas production (a+b) and gas production rate constants for the insoluble fraction (c) (P>0.05). Furthermore, cumulative gas production from 96 h of incubation did not changed by hog plum complementation and were ranged from 154.7 to 158.8 ml/ 0.5 g DM. Ruminal pH of 2 h, 4 h after incubation and average pH were not significantly different among various doses of hog plum complementation (P>0.05). Average NH 3-N concentration were highest increased when hog plum supplementation at 2.0 to 2.5 mg and increased by 16.4 to 17.5%, respectively compared to no supplemented group. At 2 h after incubation, there were no changed on protozoal counts (P>0.05), whereas the reduction of protozoal counts were found when added hog plum at 4 h after incubation (P<0.05). In addition, mean concentration of protozoa was reduced when increasing doses of added hog plum (P<0.05). Supplementation of hog plum at 2.0 to 2.5 mg could reduce protozoal population by 71.2% when compared to no supplemented group. Supplementation of hog plum did not alter IVDMD and IVOMD and were average ranged from 57.1 to 58.5% DM and 62.4 to 64.1% DM, respectively (P>0.05). It could be summarized that supplementation hog plum did not adversary affect ruminal fermentation, kinetic of gas and in vitro digestibility, whereas population of protozoa was decreased when supplementation hog plum up to 2.0 mg.
