Effects of Different Technological Forms of the Perilla frutescens in the Diet on Ruminal Fermentation, Milk and Plasma Fatty Acid Composition, Ruminal Biohydrogenation and Milk Quality in Dairy Goats Selma Büyükkılıç Beyzi, İsmail Ülger, Emrah Kaya, Buğra Ocak, Yusuf Konca Veterinary Medicine and Science, 2024 BackgroundFatty acids can be protected by changing their structure or form against microbial activity, and the different forms of fatty acids can modulate the ruminal biohydrogenation rate and contribute to the desired fatty acid profile in milk fat.ObjectivesThe study investigated the effects of perilla (Perilla frutescens) dietary supplementation in the diet in different technological forms (seed, oil and formaldehyde‐treated oil) on milk, plasma and ruminal fatty acid composition, and milk quality in lactating goats.MethodsThe four dietary treatments consisted of (1) no supplementation, basal diet (CON); (2) perilla supplementation as seed at 44.7 g/kg (consisting of 20 g/kg oil (PS)); (3) perilla supplementation as oil at 20 g/kg (PO); (4) perilla supplementation as formaldehyde treated oil at 20 g/kg (protected perilla oil [PPO]). The experiment was implemented in a double 4 × 4 Latin square trial design, and sampling was carried out for 7 days after 21 days of adaptation.ResultsPerformance parameters were not affected by P. frutescens supplementation to the diet. PO decreased milk fat, whereas PPO increased milk fat. Milk cholesterol was not affected by P. frutescens dietary supplementation. Perilla oil supplementation in different forms to the diet did not affect ruminal pH, VFA and methane production. Perilla oil supplementation in different forms to the diet did not also affect the concentration of blood serum glucose, cholesterol and non‐esterified fatty acids. Perilla supplementation to the diet increased the milk conjugated linoleic acid (CLA), C18:3n‐3, C22:5n‐3, C20:5n‐3, C22:6n‐3 and polyunsaturated fatty acid (PUFA) concentrations, and PPO group showed the greatest values. Ruminal palmitic (C16:0) acid was decreased, and in perilla groups, stearic acid (C18:0) concentration had the lowest, and ruminal c‐9, t‐11 CLA concentration had the highest value in PPO.ConclusionsIt has been found that the most effective form of perilla oil in increasing milk quality is that with formaldehyde treatment (protected form). Perilla oil, which is a rich source of omega 3 in the diet, can be used to increase milk quality in goats without adversely affecting performance, ruminal fermentation and blood parameters.

Chemical composition, nutritive value and rumen methane potential of some legume tree pods Livestock Research for Rural Development, 2018
Effect of species on chemical composition, metabolizable energy, organic matter digestibility and methane production of some legume plants grown in Turkey Omer Suha Uslu, Ozer Kurt, Emrah Kaya, Adem Kamalak Journal of Applied Animal Research, 2018 The aim of the current experiment was to evaluate the chemical composition, metabolizable energy (ME), organic matter digestibility (OMD), gas and methane production of some legume plants estimated by in vitro gas production technique, and to determine the relationship among chemical composition, ME, OMD, gas and methane production of some legume plants. Although species has a significant effect on the chemical composition, gas production, ME and OMD species has no effect on methane emission of legume hays. Neutral detergent fibre (NDF) and acid detergent fibre (ADF) ranged from 22.86% to 42.93% and 20.24% to 37.16% respectively. Crude protein (CP) contents of legume hays ranged from 13.61% to 20.55%. Neutral detergent fibre and ADF contents of legume plants are negatively correlated with gas production, ME and OMD. It can be concluded that legume plant studied in the current experiment showed a wide nutritional diversity and will provide not only protein but also fibre for livestocks. They may exhibit complementary role for ruminant animals grazing on poor quality forages. Legume species studied in the current experiment had a no anti-methanogenic properties.
Comparison of the chemical composition and anti-methanogenic potential of liquidambar orientalis leaves with Laurus Nobilis and Eucalyptus globulus leaves using an in vitro gas production technique Ismail Ulger, , Adem Kamalak, Ozer Kurt, Emrah Kaya, Inan Guven, and Ciencia E Investigacion Agraria, 2017 The aim of the present study was to compare the leaves of Liquidambar orientalis with leaves of Laurus nobilis and Eucalyptus globulus in terms of chemical composition and anti-methanogenic potentials using the in vitro gas production technique. Species had a significant effect on the chemical composition, gas production, methane production, metabolisable energy and organic matter digestibility of tree leaves. Crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and condensed tannin (CT) contents of tree leaves ranged from 9.11 to 12.8, 22.49 to 35.85 and 32.76 to 49.31, 1.55 to 9.29% respectively. Gas production, methane production, metabolisable energy (ME) and organic matter digestibility (OMD) ranged from 21.72 to 31.54 ml, 2.62 ml to 4.41 ml, 6.62 to 9.24 MJ /kg DM, 41.23 to 54.84 % respectively. It is likely that leaves of Liquidambar orientalis will be more effective for methane mitigation in ruminant animals as compared with Eucalyptus globules and Laurus nobilis. However before large implication it should be tested in vivo to evaluate the effect of leaves of Liquidambar orientalis on animal production

Effect of peppermint (Mentha piperita) essential oil on rumen microbial fermentation of barley grain C.O. Ozkan, A. Kamalak, A.I. Atalay, A. Tatliyer, E. Kaya Journal of Applied Animal Research, 2015 The objective of this experiment was to determine the effect of peppermint essential oil on in vitro gas, volatile fatty acids (VFA), methane, ammonia production, metabolisable energy (ME) and organic matter digestibility (OMD) of barley grain. Gas productions of barley grain were determined at 3, 6, 12, 24, 48, 72 and 96 h incubation times in the presence (100, 200, 400, 800 and 1200 mg/L) and in the absence of peppermint essential oil. The supplementation of peppermint essential oil significantly (P < 0.001) reduced the total gas production (A), ME, OMD, total VFA, methane and ammonia production. The mean decreases in A, OMD, ME, total VFA, methane and ammonia production of barley grain were 0.0338, 0.0341, 0.0054, 0.041, 0.023 and 0.0079 units per mg peppermint essential oil supplementation, respectively. In conclusion, the current study has provided significant information on the anti-microbial activity of peppermint essential oil causing an inhibition of the overall fermentation process of barley grain. Therefore, before large scale implementation, further investigations are required to determine the effect of peppermint essential oil on voluntary food intake, animal performance and the profitability of the supplementation in vivo.
Determination of potential nutritive value of cotton gin trash produced from different feed companies Çagri Ozgur Ozkan, Mustafa Boga, Ali Ihsan Atalay, Inan Guven, Emrah Kaya Journal of Applied Animal Research, 2015 The aim of this study was to determine the potential nutritive value of cotton gin trash obtained from five different companies using chemical composition and in vitro gas production technique. There was considerable variation among cotton gin trash obtained from five different companies in terms of chemical composition and in vitro gas production, metabolizable energy (ME) and organic matter digestibility (OMD). The crude protein (CP) contents of cotton gin trash ranged from 6.59% to 12.55% on dry matter (DM). Neutral detergent fibre (NDF) and acid detergent fibre (ADF) contents ranged from 49.24 to 62.22% on DM and 40.73 to 48.31% on DM respectively. The gas production ranged from 22.91 to 33.51 ml of 200 mg of DM after 24-h incubation. The ME and OMD contents of cotton gin trash ranged from 5.38 to 7.09 MJ/kg DM and 37.44 to 52.69% respectively. In conclusion, chemical characterization of CP, OMD and ME suggests that the cotton gin trash moderate level of CP concentration and was digestible therefore it could be said that cotton gin trash will provide roughage of an acceptable quality for ruminant animals.
