“…It was surprising to observe that milk yield was higher in the YM fed groups during the last few weeks of this study; however, this finding is in agreement with our previous study, in which YM supplementation during mid lactation sustained milk production [16]. However, other studies were not able to observe any changes in milk yield or composition in dairy cows [18] or sheep [15]. It could be argued that differences in the duration, timing, and dose of the supplementation regime could be responsible for this apparent discrepancy.…”

“…Studies on the effect of Yerba Mate supplementation in ruminants have shown that Yerba Mate supplementation increased feed intake and wool growth in lambs [14], increased milk solids in ewes [15], and sustained milk yield in mid-lactating cows [16], while its administration in growing calves can influence lipid metabolism [17]. Recently, it has been observed that Yerba Mate is an antioxidant source for increasing reducing power in milk from dairy cows [18]. Therefore, the objective of this study was to investigate the effect of Yerba Mate supplementation during the pre-partum phase of the transition period on redox balance in lactating dairy cows.…”

Dietary Supplementation of Yerba Mate (Ilex paraguariensis) during the Dry Period Improves Redox Balance in Lactating Dairy Cows

Thirty-six pregnant Holstein–Friesian cows were used to study the effect of Yerba Mate (YM) supplementation during the dry period on redox balance. The treatments groups were Control (no YM), YM 250 (250 g/cow/day), and YM 500 (500 g/cow/day). Blood samples were obtained 30 days prepartum, at calving, and monthly postpartum until four months post calving. Liveweight (LW) and body condition score (BCS) were assessed prepartum, at calving, and then postpartum monthly until the end of the trial. Plasma was analyzed for hydroperoxides (d-ROMs), advanced oxidation protein products (AOPP), and biological antioxidant potential (BAP). The oxidative stress index (OSI) was calculated as OSI = ROMs/BAP × 100. Cows were milked twice daily, and milk yield data were recorded daily. Redox balance was improved by YM supplementation, as reflected in the lower OSI values observed in the YM groups. Yerba Mate supplementation significantly affected LW, but did not affect BCS. Milk yield averaged 28.1 ± 0.40, 29.0 ± 0.48, and 29.9 ± 0.46 L/cow/day in the Control, YM 250, and YM 500 groups, respectively, but was not significant. Nutritional manipulation during the dry period with Yerba Mate has demonstrated the potential to improve redox balance and milk yield.

“…Animal studies using yerba mate are very limited, and some have reported positive results. The inclusion of yerba mate extract in dairy animals diet, ewes supplemented with dried leaves at doses of 0 and 2.5% (DM basis) and cows supplemented with dried leaves at 0, 250, 500, and 750 g/day/animal, were reported to have positive impacts on milk yield and composition [24,25]. Also, on meat quality of beef cattle [26] fed dried plant extract (0, 0.5, 1, and 1.5% of DM), greater antioxidant activity of meat and milk were also reported [25,26].…”

This study aimed to evaluate levels of yerba mate (Ilex paraguariensis) extract (YME), as a feed additive in the diets of growing lambs on serum biochemical parameters and hematological indices, animal performance, body metrics and carcass traits. Thirty-six entire (nine per treatment), male growing lambs, weighing 23.8 ± 3.7 kg, were fed the experimental diets which were treatments consisting of increasing levels of YME (0, 1, 2, and 4% inclusion on a dry matter [DM] basis) during an experimental period of 53 days. The experiment was carried out in a randomized block design, which initial body weight was used as blocking factor and the results were analyzed by orthogonal contrasts (linear, quadratic, and cubic). Yerba mate extract did not change the general health status of the animals; however, inclusions of up to 2% of the extract increased globulins (p = 0.05) and white blood cell count, as segmented neutrophils (p = 0.02) and lymphocytes (p = 0.04). Additionally, inclusion of up to 2% YME increased dry matter intake, final weight gain, total and daily gain (p < 0.05), also tended to increase ribeye area and reduce fat thickness (p < 0.10); however, YME above 2% of inclusion reduced animal productive parameters (p < 0.05). In conclusion, levels up to 2% of YME were beneficial to the health and productive parameters of growing lambs.

“…This plant is rich in polyphenols with antioxidant properties (Heck and de Mejia, 2007). When fed to dairy cows, Yerba Mate increased the antioxidant activity in milk which was measured via reducing power analysis (Santos et al ., 2017).…”

This research communication addresses the hypothesis that the association of dietary vitamin E and Yerba Mate could help to prevent or decrease oxidation of milk enriched in unsaturated fatty acids (UFA). Four multiparous lactating Holstein cows were used in a 4 × 4 Latin square. Treatments were: (1) control diet with no Yerba Mate or vitamin E; (2) diet containing 375 IU/kg vitamin E; (3) diet containing 30 g/kg Yerba Mate; and (4) diet containing 375 IU/kg vitamin E and 30 g/kg Yerba Mate. To increase unsaturated fatty acids in milk, cows were fed 172 g/kg soybean seeds (on a dry matter basis). There was no interaction between vitamin E and Yerba Mate supplementation for milk antioxidant-related (polyphenols, reducing power, conjugated dienes, and TBARS) analyses. Milk reducing power was increased when cows were supplemented with Yerba Mate. Our results suggest that the association of dietary vitamin E and Yerba Mate does not help to prevent or decrease oxidation of milk in UFA.
