“…This result is relevant because it shows the maintenance of essential cellular solutes and the normal functioning of various metabolic processes (Brizzolara et al, 2020). Indeed, fatty acids composition remained similar to these found in other grapes varieties (Kapcsándi et al, 2021;Sabra et al, 2021;Vašeková et al, 2020), but the higher levels of C18:3 in treatment 450 g.ha -1 can favor winemaking, as they are precursors of alcohols, aldehydes and thiols that are essentials for herbaceous aromas and tropical notes (Pérez-Navarro et al, 2019). In fact, the application of ZnSO 4 showed no depreciative changes for the wine, as observed in the sensory analyses (Fig.…”

In grapevines, Zn is essential for normal leaf growth, shoot elongation and pollen development, allowing a fully developed berry. In this context, using as a test system Vitis vinifera L. variety Syrah, this study aimed to assess the interactions between Zn enrichment in grapes and sugars and fatty acids profiles, further considering the sensory implications of red wine production. Vineyard conditions of the soil were assessed to ensure the natural optimal development of grapevines and the workflow for Zn enrichment considered three treatments: foliar spray with water (control) and with ZnSO4 (at 450 and 900g.ha-1). After the 2nd foliar application of ZnSO4, only minor changes of Zn, Ca and P contents were found in grapes (the levels of K, Cu and S increased significantly with ZnSO4 (450 g.ha-1). At harvest, the grapes submitted to foliar application of ZnSO4 showed significantly higher levels of Zn (between 33.38 - 54.41%), but significant deviations in sugars (sucrose, glucose and fructose), fatty acids (C18:0, C18:1, C18:2, C18:3, C16:0, C<16:0) and color parameters were not found. After winemaking, relative to the control, a higher content of Zn persisted (60.59 - 63.82%), without impairing the characteristics desired by consumers. In fact, the wine with ZnSO4 (900 g.ha-1) was the most sensorially accepted.

“…Water, mineral and vitamin lick was accessible ad libitum. The concentration of biologically active substances (total polyphenols: 27.38 ± 1.38 mg GAE/g-equivalent of gallic acid) was determined in a previous study [35]. The control (C) daily diet from meadow hay, ground wheat, soybean meal, and mineral and vitamin lick was formed.…”

The aim of this study was to find the effect of dried grape pomace (GP) feeding on the nutrients digestibility coefficients and biochemical parameters of sheep blood serum. The experiment was divided into three feeding periods—C (control), GP1 (1% grape pomace concentration), and GP2 (2% grape pomace concentration). Wethers in three groups in balance cages were housed for right feces collection. The C feed diet consisted of hay, ground wheat, soybean meal, mineral and vitamin lick. An experimental diet with 1% and 2% addition of GP from the daily dry matter intake was fed. After that, digestibility coefficients (in %) were calculated by the difference between nutrient intake and excretion. Furthermore, in the wethers’ blood, biochemical parameters (mineral, energetic, nitrogen, and enzymatic profile) were analyzed. After the GP2 feeding, statistically significant higher digestibility of CP (crude protein), NFC (nonfiber carbohydrates), NDF (neutral detergent fiber), and OM (organic matter) was found. However, the addition of dried GP increased significantly the content of Cl− and decreased the value of glucose, nevertheless, their concentrations were within the reference interval. Parameters of the wethers’ blood serum nitrogen and enzymatic profile were not affected by GP feeding. Dried grape pomace in an amount of 2% diet dry matter can be considered a suitable source of nutrients in sheep feeding, which in addition should improve the digestibility of diet crude protein.

It was published, that grape pomace has a positive effect on the animal organism and is also a rich source of fatty acids. The inclusion of grape pomace in the geese feed mixture was the main objective of the following experiment. The addition of grape pomace into the feed mixture was used to investigate to what extent will affect the fattening parameters of geese and the profile of fatty acids analysed from the abdominal fat of geese. The experiment was carried out on 20 geese (Czech goose breed). Two groups were formed to obtain the same average weight. The average weight of the experimental group at the beginning was 1857 ±196 g. The average weight of the control group was 1872 ±248 g. For 49 days, both groups were fed a commercial complete feed mixture for geese fattening while in the experimental group 1% of the feed mixture was replaced by dried grape pomace. The average weight of geese of the control group at the end of fattening was 5579 ±770 g and of the experimental group 5752 ±752 g. The addition of dried grape pomace to the feed mixture in the fattening of geese increased the average daily weight gain of geese by 5.2% (P ˃0.05), liver weight by 22.5% (P <0.05) and increased the content of monounsaturated fatty acids by 2.5% (P >0.05), especially oleic acid by 3.0% (P >0.05). A reduced content of polyunsaturated fatty acids by 1.5% (P >0.05) and decreased saturated fatty acid content by 3.2% (P >0.05) was detected in the experimental group. It can be concluded that the addition of grape pomace affected the liver weight of fattened gees, while the effect on fatty acids composition was insignificant.
