“…31 The high PUFA concentration, especially the high proportion of linoleic acid found in the seed (ranging from 673 to 708 g kg −1 ) wileyonlinelibrary.com/jsfa and pulp (ranging from 343 to 427 g kg −1 ) fractions, may suggest potential value for dietary inclusion with the objective of providing substrate for production of bioactive fatty acids in the rumen. In fact, in previous research, 32,33 it was reported that the inclusion of a variety of winery industry residues in ruminant feeding could be a good way of multiplying the levels of RA in milk fat. The proportion of C18:3 was higher (P <0.05) in pulp (ranging from 106 to 150 g kg −1 total fatty acids) than in seeds (ranging from 5 to 6 g kg −1 total fatty acids).…”

“…7 Szczechowiak et al, using similar experimental conditions, observed a significant increase of the proportion of C18:1 trans-11 and n-3 FAs in plasma, therefore a condition that predisposes to an increase in the concentration of polyunsaturated FAs (PUFAs) capable of reaching the mammary gland and being secreted in milk. 8 Some studies highlighted that the rumen metabolism of lactating dairy ewes is influenced by dietary supplementation with grape seed, alone or mixed with linseed, 9 and the alteration of ruminal bacterial communities of dairy cows fed with dietary supplementation with GP led to a reduction of CH 4 emissions and enhanced concentrations of monounsaturated FAs (MUFAs) and PUFAs in milk. 10 Tsiplakou and Zervas proposed the use of grape seed flour in order to increase the polyunsaturated component of the diet with the aim of increasing conjugated linoleic acid (CLA) in sheep milk.…”

BACKGROUND The aim of the study was to evaluate the nutritional properties of milk and cheese obtained from Friesian cows fed with a diet supplemented with dried grape pomace, a by‐product of the oenological industry, which is very rich in polyphenols. This approach is inspired by the increasing interest in foods containing functional ingredients that may have beneficial effects on human health. During the testing period, analyses of the chemical and nutritional properties of milk and dairy products derived from it were performed; particular attention was given to the effect of cheese ripening on the oxidative stability and fermentation process, evaluating respectively the presence of malondialdehyde and γ‐aminobutyric acid. RESULTS Dietary enrichment with grape pomace did not affect the milk composition but induced modifications in the fatty acid profiles in both milk and cheese with an increase in concentration of linoleic acid, trans‐vaccenic acid, rumenic acid and total n‐6 fatty acids. Moreover, after 30 days of cheese ripening, an increased oxidative stability and an increased concentration of γ‐aminobutyric acid were found. CONCLUSIONS Our results indicated a general improvement in nutritional parameters of milk and related cheese obtained from Friesian cows that received the feeding enrichment with dried grape pomace. Further analysis should be performed to improve knowledge of the chemical and microbiological mechanisms at the source of these findings. © 2019 Society of Chemical Industry

“…Similarly, rumenprotected γ-aminobutyric acid acts as an antioxidant and has been associated with increased dry matter intake (DMI), and better lactation performance (Wang et al, 2013). Several studies have reported the effects of feeding grape seed related products; for instance, grape seed and grape marc meal extract (GSGME), a plant extract rich in flavonoids, was associated with increased milk yield ; likewise, grape seed supplementation was shown to increase the accumulation of ruminal acid (CLA cis-9,trans-11) and fatty acid concentration of Sarda dairy sheep and could be useful to decrease the extent of oxidation of unsaturated fatty acids of sheep milk (Correddu et al, 2016). Grape seed extract was also shown to modulate oxidative stress and inflammation status in humans and to improve insulin sensitivity (Kappagoda et al, 2015).…”

Aims to investigate the effects of grape seed proanthocyanidin extract (GSPE) on production performance, metabolism, and anti-oxidative status of Holstein dairy cattle in early lactation. Forty-eight multiparous Holstein dairy cattle were assigned to four groups (CON, G20, G40 and G80) and supplied with 0, 20, 40, and 80mg GSPE/kg of body weight/day. G20 significantly increased milk yield compared with other groups. Milk protein and non-fat-solids were increased in G20, G40 and G80 groups compared with the control group only at the 7th day during the experiment. No significant difference was observed in milk fat and somatic cell count, nor on parameters of energy metabolism in blood, liver function and kidney function between the four groups. There was no significant difference in glutathione peroxidase, superoxide dismutase, total antioxidant capacity, and hydrogen peroxide between the groups; but the malondialdehyde content of G20 significantly increased at day 14 in comparison with CON, and tended to increase at the 28th day. In conclusion, feeding 20mg GSPE/kg of body weight/day was associated with a significant increase in milk yield without detrimental effects on liver or kidney function and with substantial energy metabolism and antioxidant parameters improvement in early lactation dairy cattle.
