“…In particular, a negative relationship has been observed between the amount of total phenols contained in BPRP (expressed in g/kg DM) and DMI (expressed in kg/d) only in sheep (y = 22.872x + 47.765; R 2 = 0.8118) [16,[88][89][90][91], as reported in Figure 2. In contrast, in goats, this association was not observed (y = −1.2727x + 18.586 R 2 = 0.0003; Figure 2) [40,[92][93][94]. Probably, considering their different feeding behaviors (goats are intermediate feeders and ewes are grazers) [95], goats developed more strategies against these types of feeds rich in polyphenols (e.g., the presence of proline-rich proteins in the saliva [96] and a higher capacity of the saliva to bind tannins [97][98][99][100], which can help this species better control the toxicity of tannins than grazers [101].…”

“…Similarly, some forages (e.g., Vicia sativa L., Lotus corniculatus L., Hedysarum coronarium L., and Lotus pedunculatus) can also contain a high number of polyphenols that affect the performance and metabolism of animals [103][104][105][106]. Relationship between total phenol content of by-products naturally rich in polyphenols (BPRP) (expressed in g/kg DM) and dry matter intake (DMI, expressed in kg/d) in sheep (♦) and goats ( ) (goats: [40,93,94,107]; sheep: [16,17,90,91]).…”

“…The latter aspect is very important since antioxidant compounds can contribute to extending the shelf-life of products, as oxidative reactions are an important process that contributes to the deterioration of foods characterized by highly unsaturated lipids, which are extremely susceptible to oxidation. Positive effects, in terms of increased milk antioxidant capacity, are reported for both sheep and goats when BPRP are included in their diets (grape residue flour was added to the diets of dairy sheep) [28,94]. In these studies, a direct antioxidant effect could be hypothesized even though the antioxidant outcome of the polyphenols could be also ascribed to an indirect mechanism mediated by its effect on the general oxidative status of the animal [87].…”

Recently, the interest in industrial by-products produced at the local level in Mediterranean areas, resulting from fruit and vegetable processes, has increased because of their considerable amounts of bioactive compounds, including polyphenols. In this review, we analyze the most recent scientific results concerning the use of agro-industrial by-products, naturally rich in polyphenols (BPRP), in the diets of small dairy ruminants. Effects on milk production, milk and rumen liquor fatty acid profile, metabolic parameters, and methane production are reviewed. The feed intake and digestibility coefficients were generally depressed by BPRP, even though they were not always reflected in the milk yield. The main observed positive effects of BPRP were on quality of the milk’s FA profile, antioxidant activity in milk and blood, a reduction of rumen ammonia, and, consequently, a reduction of milk and blood urea. The expected beneficial effects of dietary polyphenols in small ruminants were not always observed because of their complex and variable matrices. However, owing to the large quantities of these products available at low prices, the use of BPRB in small ruminant nutrition offers a convenient solution to the valorization of residues arising from agricultural activities, reducing feed costs for farmers and conferring added value to dairy products at the local level, in a sustainable way.

“…The improvements rumen fermentation parameters and favourable impacts on blood antioxidant parameters in sheep were reported with Chinese herbs (Qiao et al, 2012). Similarly, diet containing 18% of date palm ( Phoenix dactylifera L.) increased TAC of milk and blood in dairy goats (Sharifi, Bashtani, Naserian, & Farhangfar, 2015). The linearly increase in TAC was within increasing levels of date palm seed (Sharifi, Bashtani, Naserian, & Farhangfar, 2017).…”

The objective of this study was to determine the effect of dry medicinal plants (wormwood, chamomile, fumitory and mallow) and dietary substrates containing a mix of the plants on the end products of in vitro ruminal and intestinal fermentation, rumen protozoan population and ruminal antioxidant capacity of sheep. The experiment consisted of fermentations with the four plants used individually as the sole substrate and fermentation of a mix of medicinal plants (Plants): meadow hay:barley grain (MH:B), 700/300 w/w and Plants:MH:B, 100/600/300 w/w/w. The experiment was conducted using the in vitro gas production technique (IVGPT) with 35 ml of buffered inocula and approximately 250 mg (DM basis) of substrate incubated for 24 hr at 39°C in anaerobic conditions. Quantitative analyses of the bioactive compounds by ultra‐high‐resolution mass spectrometry in Plants identified three main groups: flavonoids (22 mg/g DM), phenolic acids (15 mg/g DM) and alkaloids (3 mg/g DM). The total antioxidant capacity (TAC) of the plant extracts and rumen fluid was analysed using a ferric reducing antioxidant power assay. The values of total and individual short‐chain fatty acids, acetate:propionate ratio, pH and total gas production were significantly affected by the single plant substrates and inocula (p < .001). Apart from these parameters, the values of ammonia N, methane production and total gas produced were decreased in Plants:MH:B in comparison with MH:B (p < .001). A positive correlation was recorded between total polyphenols content and TAC of plant extracts (R2 = .778, p < .001). The counts of the total ciliate protozoan population in rumen fluid after 24 hr of fermentation were not significantly different (p > .05). Results suggest that the dietary substrate containing the medicinal plant mix possessed strong ruminal antioxidant capacity, had the potential to reduce methane emission and ammonia concentration and caused desirable changes in the gastrointestinal ecosystem.

“…Al-Farsi and Lee (2008) and Sharifi et al (2015) reported that date fruit consists of 70-88% carbohydrates, most of which is in the form of sugars, mainly glucose, sucrose and fructose. Consequently, date fruits are considered a concentrate source of energy.…”
