“…On the other hand, caution should be paid when breeding animals are fed phytoestrogenic polyphenols-rich (flavonoids, nonflavonoids, and phenolic acids) plants such as soybean, linseed, clover, milk thistle seeds, rosemary leaves [ 67 ], soybean isoflavones supplement [ 45 ], and green tea powder [ 5 ]. Indeed, bioavailability of tannins seems to be more restricted due to their high molecular weight and weaker absorption through the intestine, which may limit their effects [ 75 ].…”

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

2020

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.

“…Sánchez-Carranza et al (2017) reportaron que frutos y hojas de C. coriaria son una fuente rica en taninos condensados, como ácido gálico, galato de etilo y ácido tánico, como base de taninos hidrolizables, por lo que la actividad biológica reportada en este estudio podría estar relacionada con estos metabolitos. Además, las dosis de concentración empleadas en el estudio, fueron inferiores al 9 % (90 g/kg de materia seca) de taninos para causar mortalidad en el animal (Nawab et al, 2020). Frutos et al (2004) alimentaron diariamente corderos de engorde con dietas adicionadas con 20.8 g/kg de materia seca, y no observaron efectos tóxicos ni disminución en la producción de los animales.…”

Haemonchus contortus is a gastrointestinal parasite of small ruminants. The objective was to evaluate the effect of the acetonic and ethanolic extract of the Caesalpinia ciriaria fruits on the egg hatching inhibition (EHI) of Haemonchus contortus in small ruminants. The inhibition effect of hatching was evaluated at different concentrations of the extracts (acetonic: 20.0, 10.0, 5.0, 2.5, 1.2 and 0.6 mg / mL), (ethanolic: 6.15, 3.12, 1.56 and 0.78 mg / mL) and methanol to the 4% with distilled water as negative control and 0.5% ivermectin as positive control, were used. The ovicidal effect data were analyzed with a completely randomized design by analysis of variance using the general linear model and the tukey test (P <0.05); the lethal concentrations (LC50 and LC90) were estimated by the Probit analysis of the statistical analysis systems (SAS) program. Concentration dosage depended extracts effects, were observed, where the ovicidal activity was comparatively similar to the positive control to the doses of 1.2 mg / mL for the acetonic extract (AE) and 0.78 mg / mL for the ethanolic extract (EE), respectively (P <0.0001). The LC50 were AE = 0.23 mg / mL and EE = 0.014 mg / mL; LC90 AE = 1.04 mg / mL and EE = 0.14 mg / mL, for each extract, respectively. The results indicate that the EHI of the extracts elaborated with the C. coriaria fruits in acetonic and ethanolic solvent extract secondary compounds that have activity against H. contortus eggs, nevertheless, requires of greater investigations as antiparasitic for its direct animal use

“…Although tannins (table 2) are considered anti-nutritional factors, however, when used in small concentrations in diets, they are efficient bactericides, fungicides, antioxidants, mineral binders, and astringents (Nawab et al 2020), thus the inclusion of tannins is suggested. These beneficial polyphenols in small amounts in poultry and other nonruminant diets (Martínez et al, 2021).…”

With the objective of determining the nutritional constituents, amino acids and the content of secondary metabolites of the foliage meal of Tithonia diversifolia. For this, plant material was collected 70 days after regrowth. The percentages of DM, CP, P, Ca, Si, CF, NDF, ADF, ADL, Cel, Hcel, CC were determined; amino acid profile (methionine, cystine, methionine + cystine, lysine, threonine, aspartic acid, glutamic acid, proline, glycine, alanine, valine, isoleucine, leucine, serine, phenylalanine, arginine, histidine), and content of TT, TP, TCT, TBCT, FCT, Flv, Sap, Alk, Trit and TS. For statistical processing, descriptive techniques (mean and standard deviation) were used. The plant material of Tithonia diversifolia analyzed showed percentages of 22.23, 2.62, 0.013, 45.7, and 29.8% and 6.09 MJ/kg (CP, Ca, P, NDF, ADF and ME). For the secondary metabolites, they presented concentrations of 5.35, 12.38, 13.7, 9.58, 4.15, 24.49, 0.86, 1.36, 7.71 and 10.75 g/kg MS for total tannins, total phenols, total condensed tannins, total bound condensed tannins, free condensed tannins, flavonoids, alkaloids, saponins, triterpenes and total steroids). The highest concentrations of amino acids were for lysine, aspartic acid, glutamic acid, proline, glycine, alanine, valine, leucine, serine and phenylalanine with values of 13-30 g/kg of protein. It is concluded that the foliage meal of Tithonia diversifolia presents an adequate relation in its quality.
