“…In these plants, tannins can be found in almost 80% of woody perennial dicotyledonous species and 15% of annual and herbaceous perennial dicotyledons such as trees, shrubs, legumes, herbs, and cereal grains [ 6 , 7 ]. Many of them are used as animal feeds such as Acacia [ 31 ], Dichrostachys, Dorycnium, Hedysarum, Leucaena, Lotus [ 28 ], Onobrychis, Populus, Rumex and Salix [ 30 ], and Quercus robur with prevalence condensed tannins accounting for up to 20% of the dry matter [ 46 ].…”

Polyphenols in Farm Animals: Source of Reproductive Gain or Waste?

Reproduction is a complex process that is substantially affected by environmental cues, specifically feed/diet and its components. Farm animals as herbivorous animals are exposed to a large amount of polyphenols present in their natural feeding system, in alternative feed resources (shrubs, trees, and agro-industrial byproducts), and in polyphenol-enriched additives. Such exposure has increased because of the well-known antioxidant properties of polyphenols. However, to date, the argumentation around the impacts of polyphenols on reproductive events is debatable. Accordingly, the intensive inclusion of polyphenols in the diets of breeding animals and in media for assisted reproductive techniques needs further investigation, avoiding any source of reproductive waste and achieving maximum benefits. This review illustrates recent findings connecting dietary polyphenols consumption from different sources (conventional and unconventional feeds) with the reproductive performance of farm animals, underpinned by the findings of in vitro studies in this field. This update will help in formulating proper diets, optimizing the introduction of new plant species, and feed additives for improving reproductive function, avoiding possible reproductive wastes and maximizing possible benefits.

“…A study reported the chemical composition of D. angustifolia for crude protein (CP), neutral detergent fiber (NDF) and acid neutral detergent fiber (ADF) 108, 298 and 216 g/kg dry matter (DM), respectively. Better in vitro organic matter digestibility (51%) and metabolizable energy (ME; 11 MJ/kg DM) were reported for D. angustifolia (Mengistu et al, 2017). Although there is limited information on the animal performance, particularly to D. angustifolia feeding practice, there is plenty of information for other shrubs (Abraham et al, 2015).…”

Background Protein feed resources for ruminant animal productions are deficit in Ethiopia. Objectives To evaluate the supplementation effects of dried Dodonaea angustifolia leaves (DDL), dried traditional brewery by‐product locally called atella and their mixtures on nutrient utilization and growth performance of Farta sheep fed natural pasture hay (NPH) as basal diet. Methods Twenty‐five yearling intact male Farta sheep with average initial body weight of 14.53 ± 1.35 kg (mean ± SD) were used for the study. The experimental sheep were allocated into five blocks of five animals based on their initial body weight. The experiment lasted for 90 days of feeding trial followed by 7 days of digestibility trial. The experimental feeds were NPH ad libitum + 100% DDL + 100 g wheat bran (WB; T1), NPH ad libitum + 75% DDL + 25% dried atella + 100 g WB(T2), NPH ad libitum + 50% DDL + 50% deried atella + 100 g WB (T3), NPH ad libitum + 25% DDL +75% dried atella +100 g WB (T4) and NPH ad libitum + 100% dried atella + 100 g WB (T5). Results NPH, DDL and dried atella contained 7.42, 15.39, 21.13% crude protein (CP) and 66, 36, 34% neutral detergent fiber, respectively. Sheep supplemented with increasing level of atella had more dry matter intake (DMI) and crude protein intake (CPI) and the highest of these DMI and CPI were in T5 (868 g/d for dry matter and 113 g/d for CP). This progressive increased CPI from T1 up to T5 was reflected in a significant (p < 0.001) fibers and estimated metabolizable energy intake in the order of T5 > T4 > T3 > T2 > T1. Significant difference (p < 0.001) was recorded on nutrient utilization and the highest was for T5 and lowest for T1. Average daily gain (ADG) and feed conversion efficiency (FCE) were significantly (p < 0.001) increased as the atella inclusion level increased. Sheep in T4 and T5 had the highest ADG and FCE with the order of T5 = T4 > T3 > T2 > T1. ADG was correlated positively and highly significant with nutrients intake and digestibility. Conclusion Atella supplementation better than DDL and then their mixture (T2–T4) supplementation could be recommended in sheep fattening in the study area.

“…Although interspecies differences in the fermentative activity of inocula from ruminants have long been established, only limited information is available on the comparison of goat and cow rumen fluid within the effectiveness of tannin‐containing forages . In a previous study, a marked decline in in vitro CH 4 concentration was observed in browse species fermented in inoculum from goats not adapted to tannin‐containing diets in the presence of a tannin binding agent, polyethylene glycol. It was, however, unclear whether the observed fermentation patterns were due to the goat inoculum or were specific to the tannin‐containing browse species used.…”
