“…As recently reported [ 9 ], grape pomace, olive byproducts and citrus pulp are just a few examples of sources of high added value ingredients for sustainable livestock diets [ 10 , 11 , 12 ]. In the research and development of products that can contribute to reducing the environmental impact and safeguarding the environment, the valorization of chestnut and quebracho biomasses is actually applied for livestock, and several plant extracts diversely composed in specialized metabolites, such as tannins, saponins, and flavonoids, as well as in essential oils [ 13 , 14 ], are of interest.…”

In recent years, animal husbandry has aimed at improving the conditions of livestock animals useful for humans to solve environmental and health problems. The formulation of animal feeds or supplements based on antioxidant plant compounds is considered a valuable approach and an alternative for livestock productivity. Forest biomass materials are an underestimated source of polyphenolic compounds whose sustainable recovery could provide direct benefits to animals and, indirectly, human nutrition. In this context, an alcohol extract from leaves of Fagus sylvatica L. was first investigated through an untargeted ultra-high-performance liquid chromatography–high-resolution tandem mass spectrometry (UHPLC-HRMS/MS) approach. Then, it was fractionated into a fatty acid-rich and a polyphenolic fraction, as evidenced by total lipid, phenol, and flavonoid content assays, with antiradical and reducing activity positively correlated to the latter. When tested in vitro with rumen liquor to evaluate changes in the fermentative parameters, a significant detrimental effect was exerted by the lipid-rich fraction, whereas the flavonoid-rich one positively modulated the production of volatile fatty acids (i.e., acetate, butyrate, propionate, etc.).

“…Previously recorded data have shown that hemp seed has valuable nutritional characteristics [ 36 ], for use as feedstuff for dairy cows [ 37 , 38 ], lambs [ 39 ] and sheep milk production [ 40 ], poultry [ 41 , 42 ], and pigs [ 4 ]. These studies focused on hemp seed’s potential in monogastric feeding as a low-cost dietary component because it doesn’t necessitate irrigation, pesticides, or large amounts of synthetic fertilizers, and as a therapeutic feedstuff as suggested by the Borhade [ 43 ].…”

This study shows the effects of dietary hemp seed oil on the milk composition, blood immunoglobulins (Ig), and enteric methane (E-CH4) production of primiparous sows, and their offspring’s response at three time points. A bifactorial experiment was conducted for 21 days (d) on 18 primiparous sows (195 ± 3 days old). The sows were fed two diets: (i) a control diet (SO) based on soybean oil (1.6%), with an 18.82 n-6:n-3 polyunsaturated fatty acids (PUFA) ratio; (ii) an experimental diet (HO) based on hemp seed oil (1.6%), with a 9.14 n-6:n-3 PUFA ratio. The milk contained an elevated level of linoleic acids (LA), n-3 FA, and especially alpha-linolenic acids (ALA), while the n-6:n-3 ratio declined using hemp oil. The Ig concentration was higher in colostrum than in milk. In the first few hours, the IgG in the plasma of piglets was more than double that of maternal plasma IgG (+2.39 times). A period effect (p < 0.0001) for IgG concentration in the plasma of piglets was recorded (40% at 10 d, respectively 73% lower at 21 d than 12 h after parturition). However, the sow diet did not affect Ig (p > 0.05). The frequency of diarrhoea declined after about 7 d. The value of the rate of diarrhoea was 6.2% lower in the PHO group. We found a 4.5% decline in E-CH4 in the HO group. Applying multiple linear regression, feed intake, n-6:n-3 ratio, ALA, and lean meat were potential indicators in estimating E-CH4. In conclusion, sow dietary hemp seed oil increased lean meat %, milk EFA, and milk IgM. Significant changes in the other dependent variables of interest (body weight, plasma Igs in sows and offspring, E-CH4 production) were not recorded. There was reduced diarrhoea which shows that EFA could play a therapeutic role in the incidence of diarrhoea and in lowering of E-CH4 emission in sows and progeny. All dependent variables were significantly altered at different time points, except for fat concentration in milk and sow plasma IgG.

“…Each year a large quantity of agro-industrial byproducts is generated as a result of the processing of agricultural crops, representing an environmental concern. Many of these agro-industrial residues have been used in animal diets, representing a major opportunity for the development of a circular economy, improving economic and environmental sustainability [ 12 ].…”

“…Many coproducts obtained from fruit and vegetable processing have great potential in animal nutrition due to their considerable bioactive components (i.e., polyphenols, flavonoids and tannins) [ 12 ]. The inclusion of all the above-mentioned coproducts in animal diets could improve animal health and provide added value to animal products [ 16 ].…”

“…The inclusion of all the above-mentioned coproducts in animal diets could improve animal health and provide added value to animal products [ 16 ]. In fact, many reports have documented the extraction of antimicrobial and antioxidant products from agro-industrial byproducts such as rice bran, wheat germ, rice husk, vegetable peels, fruit seeds and essential oils from the peel or seeds of various plants [ 12 ].…”

Rising global populations and enhanced standards of living in so-called developing countries have led to an increased demand of food, in particular meat, worldwide. While increasing the production of broiler meat could be a potential solution to this problem, broiler meat is plagued by health concerns, such as the development of antimicrobial resistance and lower meat quality. For this reason, the supplementation of poultry feed with vitamins and antioxidant compounds, such as polyphenols, has become an attractive prospect for research in this sector. Such supplements could be obtained by extraction of agricultural byproducts (in particular, grape pomaces and artichoke leaves and bracts), thus contributing to reductions in the total amount of waste biomass produced by the agricultural industry. In this review, the effects of poultry feed supplementation with bioactive extracts from grape pomace (skins and/or seeds), as well as extracts from artichoke leaves and bracts, were explored. Moreover, the various methods that have been employed to obtain extracts from these and other agricultural byproducts were listed and described, with a particular focus on novel, eco-friendly extraction methods (using, for example, innovative and biocompatible solvents like Deep Eutectic Solvents (DESs)) that could reduce the costs and energy consumption of these procedures, with similar or higher yields compared to standard methods.
