Abstract. Makmur M, Zain M, Marlida Y, Khasrad, Jayanegara A. 2019. Fatty acids composition and biohydrogenation reduction agents of tropical forages. Biodiversitas 20: 1917-1922. The study was conducted to determine the composition of fatty acids, measured rumen biohydrogenation reduction agents (total phenols and total tannins) content and selected promising plants in various species of tropical forages. Ten species of tropical forages, namely, Panicum maximum, Cynodon plectostachyus, Pennisetum purpurephoides, Pennisetum purpureum, Brachiaria decumbens, Glyricidia sepium, Calliandra calothyrsus, Stylosanthes guaianensis, Leucaena leucocephala and Indigofera zollingeriana were used in this study. The fatty acids composition (% of total identified fatty acids) which were dominant in grasses were C18: 3n-3 (29%), C16: 0 (28%) and C18: 2n-6 (23%). Whereas in legumes, the significantly higher composition of fatty acids was C18: 3n-3 (42%) followed by C16: 0 (17%) and C18: 2n-6 (17%). The average poly-unsaturated fatty acids (PUFA) composition in grasses was relatively lower (44.6%) than legumes (59%). Likewise the content of total phenols and total tannins (g/100g DM) of grasses (0.91 and 0.41) and legumes (1.72 and 0.70). The selection of the forage plant species was based on the criteria of PUFA composition and biohydrogenation reduction agents using TOPSIS method. The results obtained show that B. decumbens (grass) and I. zollingeriana (legume) had the highest preference value of 0.74 and 0.87, respectively. In conclusion, B. decumbens and I. zollingeriana are forage species that have potential to provide healthier ruminant products.

Aim: The aim of this study was to evaluate the effects of various combinations of tropical grass-legume species in rations on the biohydrogenation (BH) activity of unsaturated fatty acids (FAs), C18:0 composition, and fermentation profile in an in vitro rumen system. Materials and Methods: Samples of the following five fodder plants were used: One species of grass (Pennisetum purpureum) and four species of tree legumes (Leucaena leucocephala, Gliricidia sepium, Calliandra calothyrsus, and Indigofera zollingeriana). The following eight experimental diets were evaluated: 50% P. purpureum + 50% L. leucocephala (LL I); 50% P. purpureum + 50% G. sepium (GS I); 50% P. purpureum + 50% C. calothyrsus (CC I); 50% P. purpureum + 50% I. zollingeriana (IZ I); 75% P. purpureum + 25% L. leucocephala (LL II); 75% P. purpureum + 25% G. sepium (GS II); 75% P. purpureum + 25% C. calothyrsus (CC II); and 75% P. purpureum + 25% I. zollingeriana (IZ II). Each ration was replicated 3 times. In vitro rumen incubation was performed for 48 h, according to the Tilley and Terry method. Determination of the FA profiles of the forage materials and rumen fluid samples was performed using gas chromatography. Results: The percentage of polyunsaturated FA (PUFA) in the forage materials ranged from 34.18% (P. purpureum) to 74.51% (C. calothyrsus). The percentage of monounsaturated FA (MUFA) ranged from 5.06% (P. purpureum) to 8.71% (L. leucocephala). The percentage of saturated FA (SFA) was the lowest at 19.12% (C. calothyrsus) and highest at 60.76% (P. purpureum). In vitro BH of C18:3 n-3, C18:2 n-6, C18:1 n-9, and C18 PUFA in the experimental diets ranged from 72% to 100%. The BH of C18:1 n-9 in GS I (80%) and IZ I (72%) was significantly different (p<0.05). The percentage of C18:0 was 10-50% and significantly different (p<0.05) among treatments, with the highest (of 50%) in GS II. No significant differences (p>0.05) were observed in the fermentation parameters (pH, total volatile FAs, in vitro dry matter digestibility, and in vitro organic matter digestibility) among the treatments, except in NH3 concentration (p<0.05). Conclusion: The various combinations of tropical legumes do not have significant inhibitory effects on the BH of C18:2 n-6, C18:3 n-3, and C18 PUFA after in vitro incubation for 48 h. Furthermore, an increase in the tropical legume ratio in the ration tends to suppress C18:0 formation after the fermentation simulation process. IZ I has the potential to reduce C18:1 n-9 (MUFA) disappearance and yield an ideal rumen fermentation profile.

Composition And Structure

In order to confirm the substitutability of palm oil for lard, the fatty acid composition and their distribution at the Sn-2 position of triglycerides in three kinds of palm oil products and five kinds of lard products were investigated. The results obtained were as follows. Palm oil has similar saturated fatty acids composition (C16:0, C18:0, C18:1, C18:2) with lard, and has slightly lower unsaturated fatty acids content than lard. The Sn-2 position of palm oil is mainly distributed with unsaturated fatty acids (C18:1, C18:2), while the Sn-2 position of lard is mainly distributed with saturated fatty acids (C16:0, C18:0), which is maybe the cause why palm oil is easier to be digested and absorbed than lard.

In the fatty acid composition of total lipid of the soft coral Bebryce sp., the concentration of unsaturated fatty acid predominates. The composition of saturated fatty acids is very diverse, including all saturated fatty acids from C14 to C26. The unsaturated fatty acids with high concentration are C20: 4n-6, 20:5n-3, 22:6n-3, 24:5n-6, 26:3n-6, 26:2n-6, 26:2n-7, 28:3n-6. In the fatty acids composition of the studied coral, there is presence of characterized fatty acids for the existence of sponges C25-C28 (demospongic fatty acids) with total content 29,86%. Most of the Bebryce coral species do not have zooxanthellae, therefore, in the fatty acids composition, either it is lack or contains only a small amount of markers fatty acids for zooxanthellae such as 18:5n-3, 18:4n-3, 18:3n-6, 20:4n-3. In the phospholipid content of the soft coral Bebryce sp., there is presence of characterized classes for Cnidarian animals such as phosphatidylethanolamine (PE), phosphatidylchonline (PC), phosphatidylserine (PS), phosphatidylinositol (PI), phosphonolipid is ceramide aminoethylphosphonate (CAEP). PC account for the highest concentration (37,20% of total phospholipid). The molecular species of phospholipid classes of Bebryce sp. for the first time were investigated. In the results, there we 60 phospholipid molecular species identified in 5 classes. The molecular species with high content in the classes were PE 20:4/18:1e, PE 20:4/19:1, PC 20:4/18:0e, PC 20:4/16:0e, PS 24:5/18:0e, PI 24:5/18:0, CAEP18:2base/16:0 and CAEP 18:1base/16:0.

Surveys were conduced in 16 sites in the State of São Paulo to evaluate the phytoseid mite fauna on some of the most common grass species in that State: Brachiaria decumbens Stapf., Brachiaria brizantha (Hochst. ex A. Rich.) Stapf, Brachiaria ruziziensis R. Germ & C.V. Evrard, Melinis minutiflora Beauv., Panicum maximum Jacq. and Pennisetum purpureum Schumach. Twenty known species and one new species (Proprioseiopsis biologicus Lofego, Demite & Moraes sp. nov.) were found. Two species are reported for the first time in the American continent: Neoseiulus benjamini Schicha and Typhlodromus (Anthoseius) neobakeri Prasad . Seven of the species collected have been reported in Brazil from different crops. The largest number of specimens and of species of phytoseiids was found on M. minutiflora. The results of this study indicate that grasses may play a role in agroecosystems and pasture lands, serving as reservoirs of phytoseiids that prey upon mite pests.
