“…Results presented herein showed no effects of PTSO on total or individual VFA, nor in ammonia N concentrations, and agrees with Yang et al [18] when garlic powder was fed to dairy cows. This is in contrast with previous dual flow continuous culture fermenters studies that reported that PTSO affected total VFA and their proportions [16,17]. Although nutrient flow to the omasum and the calculated degradation in the rumen were only measured in one square and may have limited statistical power, averages were very similar between PTSO and control.…”

“…In a previous study, we reported its potential to modify ruminal fermentation in a direction consistent with higher propionate molar proportion, higher outflow of unsaturated fatty acids (UFA), and lower trans-10 cis-12 CLA in an effective dose between 50 and 100 mg/L using a dual flow continuous culture system [16]. In a follow up study with the same in vitro system, 90 mg/L of PTSO reduced the concentration of C18:0, suggesting an inhibition of biohydrogenation [17].…”

“…The PTSO is a modified oxygen-stable organosulfurate compound derived from garlic that can be used in normal production processes without losing its activity. In previous studies, we tested increasing doses of PTSO on rumen microbial fermentation using a dual flow continuous culture fermenter system inoculated with rumen fluid from dairy cattle, and we reported changes in the fermentation profile that suggested its potential benefits as a modifier of ruminal fermentation [16,17]. However, there are no studies exploring the effects of PTSO on rumen microbial fermentation or production performance in dairy cows.…”

Essential oils may affect rumen fermentation, nutrient digestion, and milk production and composition. The objective of this study was to test the effects of capsicum oleoresin (CAP) and propyl-propane thiosulfonate (PTSO) on rumen fermentation, total tract digestibility, and milk yield and composition in lactating dairy cattle. Six lactating Holstein cows (averaging (mean ± SD) 130 ± 40 days in milk and 723 ± 55 kg of body weight) fitted with rumen cannulae were used in a duplicated 3 × 3 Latin square design. Treatments were: a control diet (CTR), the CTR diet with the addition of 500 mg/d/cow of CAP, and the CTR diet with the addition of 250 mg/d/cow of PTSO. Dry matter intake (DMI) averaged 20.7 kg/d with a tendency towards higher intake in cows fed CAP and lower in those fed PTSO (p = 0.08). Milk yield averaged 31.8 kg/d with no difference among treatments. However, feed efficiency was higher in PTSO supplemented cows compared with CTR (1.65 and 1.41 kg of milk yield/kg of DMI, respectively; p < 0.01). At the doses used in this experiment, CAP and PTSO failed to demonstrate any effects on rumen fermentation, but PTSO increased the efficiency of feed utilization to produce milk.

“…The highest levels of C18:2 trans-10,cis-12 were detected in donkey milk (0.10%). Conjugated linoleic acid is mainly derived from the isomerization of dietary C18:2 cis-9,cis-12 in rumen or the desaturation of C18:1 trans-11 in vivo (Siurana et al,2018). The CLA in donkey milk is unique and noteworthy, especially C18:2 trans-10,cis-12.…”

Due to the diversity and limitation of determination methods, published data on the fatty acid (FA) compositions of different milk samples have contributed to inaccurate comparisons. In this study, we developed a high-throughput gas chromatography-mass spectrometry method to determinate milk FA, and the proposed method had satisfactory linearity, sensitivity, accuracy, and precision. We also analyzed the FA compositions of 237 milk samples from Holstein cows, Jersey cows, buffalos, yaks, humans, goats, donkeys, and camels. Holstein, Jersey, goat, and buffalo milks contained high content of even-chain saturated FA, whereas goat milk had higher content of medium-and short-chain FA (MSCFA). Yak and camel milk are potential functional foods due to their high levels of odd-and branchedchain FA and low ratios of n-6 to n-3 polyunsaturated FA (PUFA). Human milk contained lower levels of saturated FA, MSCFA, and conjugated linoleic acid, and higher levels of monounsaturated FA and PUFA. As a special nonruminant milk, donkey milk contained low levels of monounsaturated FA and high levels of PUFA and MSCFA. Based on the FA profiles of 8 types of milk, nonruminant milk was distinct from ruminant milk, whereas camel and yak milk were different from other ruminant milks and considered as potential functional foods for balanced human diet.

The purpose of this study was to analyze the effects of corn substitution on the rumen functions and fatty acid profile of Dorper lambs fed a diet based on palm kernel cake (PKC). Corn was replaced with PKC basal diet at the following levels: C0% = (0% corn + 75.3% PKC), C1% = (5% corn + 70.3% PKC) and C2% = (10% corn + 65.3% PKC) of diet. The rumen fermentation was carried out in vitro, and feeding trials were in vivo. Twenty-seven lambs were used to determine gastrointestinal tract content and rumen fluid fatty acid. Rumen liquor was obtained from four fistulae Dorper sheep and incubated with 200 mg of each treatment for 24 and 72 h. In vitro organic matter digestibility (IVOMD), in vitro dry matter digestibility (IVDMD), volatile fatty acids (VFA), methane estimation (CH4), rumen microbial population and fatty acid biohydrogenation were determined. The results of the in vitro study showed there were no significant differences in IVDMD, IVOMD, NH3-N, pH and VFA at 72 h. Higher significant CH4 production was observed in C0% when compared with C1% and C2%. Microbial population did not differ significantly between treatment groups. The rates of biohydrogenation were not affected by corn substitution, although a significant difference was observed in C18:1n9 (in vitro) and C18:1 t-11 (in vivo). In conclusion, the present study indicated that the corn substitution in the PKC diets maintained fermentation characteristics with an increase in unsaturated fatty acids in the rumen.
