Abstract
Milk thistle, Silybum marianum, is a medicinal plant grown for its bioactive compounds with well-documented antioxidant and hepatoprotective properties. Milk thistle has a well-established pharmacological reputation for treatments of human liver disease, but it is also used in animals. This review summarizes the experimental evidence of milk thistle's effects on animals when administered as silymarin extract (feed additive) or a feed ingredient, if administered as seed or expeller/cake with the seed residue still containing the bioactive components. The use as a feed additive or feed ingredient is motivated by the complexity of silymarin registration as a veterinary drug. In farm animals, the drug improves the animals' performance and product quality and oxidative stability, supports liver function during the productive life-cycle, improves gut-health and morphology, and can reduce intestinal pathogens. In dogs and cats, the treatment is focused on acute and chronic liver diseases including the detoxification processes and support of drug treatments including chemotherapy. In equine athletes, milk seed cake showed positive effects and a faster return of cortisol to the resting values before exercise occurred. In aquaculture, it confirms its usefulness in supporting animal health and performance. In certain studies it is not clear what has been administered, and the composition and doses are not always clearly reported. A few studies reported no effects, but none reported problems connected to milk thistle administration. However, the overall picture shows that the use of milk thistle results in improved or restored health parameters or better animal performance.

Particle Size Distribution of Plasma Lipoproteins in Donkeys from Death Valley Compared to a Sampling of Horses. Animals (Basel) 2022; 12:ani12202746. [PMID: 36290132 PMCID: PMC9597708 DOI: 10.3390/ani12202746] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2022] [Revised: 10/05/2022] [Accepted: 10/10/2022] [Indexed: 11/06/2022] Open
Abstract
Simple Summary Donkeys, like horses, belong to the Equidae family. Though they share some physical attributes, much of their physiology is quite different from horses. Both horses and donkeys can develop clinical issues associated with obesity; insulin dysregulation; and altered lipid metabolism, often termed equine metabolic syndrome or donkey metabolic syndrome, respectively. Unlike large breed horses, however, donkeys, ponies, and miniature horses are more susceptible to developing dyslipidemias. This study aimed to use a novel Lipoprint® assay to compare the lipid profiles of apparently healthy donkeys and large-breed horses to establish a baseline for future work that may lead to the use of this test methodology for the evaluation and monitoring of equids with endocrine disorders. Abstract The clinical evaluation of lipid metabolism in equids is often limited to the measurement of total cholesterol and triglyceride concentrations. This provides a limited picture of metabolic state and general health, given the continuous exchange of lipid species between various lipoproteins. Major lipoprotein classes in equids include high-density lipoprotein (HDL), intermediate-density lipoprotein (IDL), low-density lipoprotein (LDL), very low-density lipoprotein (VLDL), and chylomicrons (CM). Unlike large breed horses, donkeys are highly susceptible to hepatic lipidosis. Currently, serum triglyceride concentrations serve as a surrogate marker of hepatic lipid exportation. Both VLDL, indicative of hepatic exportation, and its metabolic end-product, LDL, are rich in triglycerides, and contribute to this value. Diagnostic assays that distinguish VLDL from LDL could be useful in better recognizing the hepatic pathology in donkeys. The compositional differences of lipoproteins across species limit the use of commercially available assays developed for the measurement of human lipoproteins in domestic animals. In this study, we evaluated a high-resolution polyacrylamide gel electrophoresis method (Lipoprint®) for separating major lipoprotein classes and sub-fractionating LDL and HDL based on particle size in a large group of donkeys, and compared the pattern to a representative set of horses. Donkeys proved an HDL-rich species, with HDL accounting for the bulk of all lipoproteins (average 78.45%, SD 6.6%, range 92.2–55%). VLDL accounted for a large portion of the total (average 21.6%, SD 6.6%, range 37.1–7.8%), with minimal amounts of LDL detected. The horses tested had higher proportions of VLDL as compared to donkeys (31.7% and 21.6%, respectively p = 0.00008). The later finding draws into question the purported relationship between VLDL, high triglycerides, and hepatic lipidosis, given the incidence of the disease in donkeys is far higher than in horses.

Dang DX, Cho S, Kim IH. Silybum marianum seed extract supplementation
positively affects the body weight of weaned piglets by improving voluntary feed
intake. JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY 2022; 64:696-706. [PMID: 35969696 PMCID: PMC9353349 DOI: 10.5187/jast.2022.e39] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/23/2021] [Revised: 03/09/2022] [Accepted: 05/10/2022] [Indexed: 11/30/2022]
Abstract
This study was conducted to evaluate the effects of dietary supplementation of
Silybum marianum seed (SMS) extract on the growth
performance, nutrient digestibility, fecal noxious gas emission, and hematology
parameters in weaned piglets. A total of 120, 21-day-old weaned piglets
([Yorkshire × Landrace] × Duroc) were randomly assigned to 3
groups based on the average initial body weight (6.46 ± 0.45 kg). There
were 8 replicate pens per treatment and 5 pigs (mixed sex) per pen. The
experimental period was 42 days. Dietary groups included a basal diet, and a
basal diet supplemented with 0.05% or 0.10% SMS extract. Feeding weaned piglets
with SMS extract containing diet significantly increased average daily gain and
average daily feed intake. Additionally, the supplementation of SMS extract had
no significant effects on nutrient digestibility, serum hematology, and fecal
noxious gas emission parameters. We considered that the supplementation of SMS
extract had positive effects on the voluntary feed intake in weaned piglets,
thus improving growth performance.

Abstract
Milk thistle (Silybum marianum) provides several possible benefits for horses, namely anti-inflammatory, antioxidant effects, hepatoprotective, and neuroprotective effects. Silybin exerts also pronounced effects on energy metabolism, that could be useful for sport horses. The aim of this study is to evaluate the effect of milk thistle seed cakes (in the form of a granulated mixture with barley) on blood biochemical parameters (total protein, albumin, bilirubin, urea, creatinine, ALT, AST, ALP, GGT, LDH, the total cholesterol, HDL-cholesterol, LDL-cholesterol, TAG, BHB, NEFA, creatine kinase, lactate, glucose, glutathione peroxidase, total antioxidant capacity, cortisol, calcium, and phosphorus) to monitor the differences between the experimental (milk thistle in feed) and control horses after exposure of the monitored horses to heavy physical exercise (combined driving) total number of horses was 12 Czech Warmblood breed horses. The digestibility of silymarin (and its individual flavonolignans) and basic nutrients are also monitored in this study. Statistically significant differences (P < .05) were found mainly in plasma cortisol and NEFA levels. The results of this study confirmed the results of our previous studies. These results suggest that the feeding of milk thistle seed cakes has a possible positive effect on horse health and energy metabolism.

Micelle silymarin supplementation to sows' diet from day 109 of gestation to entire lactation period enhances reproductive performance and affects serum hormones and metabolites. J Anim Sci 2021; 99:6444280. [PMID: 34850001 DOI: 10.1093/jas/skab354] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2021] [Accepted: 12/01/2021] [Indexed: 12/17/2022] Open
Abstract
The aim of the present study was to explore the influences of varying doses of micelle silymarin (0%, 0.05%, 0.1%, and 0.2%) supplementation on sows' feed intake, milk yields, serum hormones, and litter growth using 40 multiparous sows (Landrace × Yorkshire, parity from 3 to 5) from the 109th prenatal day to the 21st postnatal day. Each treatment included 10 sows and each sow was used as an experimental unit. On weaning day, litter weight and litter weight gain were linearly improved (P < 0.01, both), corresponding to the increasing dose of silymarin micelle in the diet. Also, litter weight, litter weight gain, and average daily gain (ADG) of piglets born to treated sows exceeded (P < 0.05) those of offspring from the control sows (0% micelle silymarin). Feed intake in week 1, week 2, and the entire lactation period was increased (linear, P < 0.01) as micelle silymarin dose increased. Body weight (BW) loss of sows during lactation was linearly reduced (P = 0.003) with the increasing amounts of micelle silymarin. Average daily milk yields during lactation were also linearly increased (P = 0.002) in treated sows, exceeding (P = 0.046) that of control sows. Also, uniform increases were observed (P = 0.037) in fat content in milk produced by treated sows on day 14 of lactation. Epinephrine concentrations and aspartate aminotransferase (AST) activity in sow serum on day 21 postpartum were linearly declined (P = 0.010) as micelle silymarin dose increased, and were both declined (P < 0.05) in treated sows compared with the control. In addition, treated sows' serum had higher activity of superoxide dismutase (SOD) at parturition and glutathione peroxidase (GSH-Px), lower oxidized glutathione (GSSG) concentrations, and GSSG/GSH (glutathione) ratio (all, P < 0.01) on day 21 of lactation. Moreover, offspring from micelle silymarin-treated sows tended to (0.05 < P <0.1) have higher serum catalase (CAT) activity and total antioxidant capacity (T-AOC) concentrations. Taken together, the results showed that sows fed increasing levels of micelle silymarin from the 109th prenatal day to the 21st postnatal day had an incremental dose-dependent effect on higher feed intake, diminished BW loss, greater milk yields, and greater litter weight at weaning, and 0.2% of micelle silymarin could be optimal to achieve the better effect.

Abstract
BACKGROUND Exercise training induces adaptive physiological and morphological modifications in the entire organism; however, excessive loads of training may increase damage in tissues. The purpose of this study was to evaluate the effect of silymarin in lung and liver histological changes in rats subjected to exercise training (ET). METHODS Male Wistar rats were subjected to an 8-week ET treadmill program 5 days per week, 60 min/session, and were previously administered 100 mg ascorbic acid or 100 mg of silymarin. RESULTS Silymarin increased alveolar and bronchial muscle size, improve vascularization, and reduced tissue inflammation. In liver, silymarin promoted the reduction of lipid content. CONCLUSION Silymarin supplementation may improve inflammation in pulmonary tissue after 8 weeks of the ET treadmill program, improve cell recovery, and reduce intrahepatic lipid content.

Abstract
Milk thistle seeds contain a mixture of flavonoids known as silymarin, which consists of silybin, isosilybin, silychristine, and silydianin. Until now, there has been no evidence of monitoring the digestibility of silymarin complex in horses. The aim of the research was to evaluate the digestibility of silymarin complex and the effect of nutrient digestibility in horses. Different daily feed doses (FD) of milk thistle expeller (0 g, 100 g, 200 g, 400 g, 700 g) were administered to five mares kept under the same conditions and at the same feed rations. Digestibility of silymarin complex was monitored by HPLC-UV. Digestible energy (DE), crude protein, crude fat, crude fiber, nitrogen-free extract (NFE), crude ash, calcium (Ca), and phosphorus (P) were determined according ISO/IEC 17025:2017. The biochemical profile of blood plasma (total protein, albumin, alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), bilirubin, total cholesterol, HDL cholesterol, LDL cholesterol, triacyl glyceride (TAG), non-esterified fatty acid (NEFA), creatine kinase (CK), creatinine, urea, glutathione peroxidase (GSH-Px), total antioxidant status (TAS), glucose, calcium, and inorganic phosphate) was investigated. Moreover, the flavonolignans of the silymarin complex in plasma were detected. Statistically significant differences (p ≤ 0.05) were found between daily doses of milk thistle expellers in digestibilities. Our findings showed the digestibility of flavonolignans increased with the daily dose and then stagnated with the dose of milk thistle seed cakes at 700 g/day.
