The feeding of domestic animals with diets in which polyphenols are present is increasingly attracting the attention of nutritionists and scientists. This review summarizes the knowledge regarding ...polyphenols' possible positive and negative effects and their bioavailability. The bioavailability of substances is a prerequisite for any postabsorption effect in vivo. Positive and negative properties have been confirmed in previous studies on the diets of domestic animals rich in polyphenols, such as secondary metabolites of plants. Free radicals are formed in every organism, leading to oxidative stress. Free radicals are highly reactive molecules and can react in cells with macromolecules and can cause damage, including in reproductive cells. Some polyphenols at specific concentrations have antioxidant properties that positively affect animal reproduction by improving the quality of male and female gametes. The intake of phytoestrogens that mimic estrogen function can induce various pathological conditions in the female reproductive tract, including ovarian, fallopian, and uterine dysfunction. The metabolism of genistein and daidzein yields the metabolites equol and p-phenyl-phenol, leading to a decline in cow fertilization. The findings so far confirm that numerous questions still need to be answered. This review points out the importance of using polyphenols that have both benificial and some unfavorable properties in specific diets.
Substantial metabolic and oxidative stress and a decrease in immune function have been associated with increased sensitivity to several diseases in dairy cows during the transition period (before and ...after calving). We investigated the effect of supplementation with linseed (LS), rich in omega-3 polyunsaturated fatty acids (n-3 PUFAs), alone, or in combination with an organic source of selenium, on the plasma metabolic parameters during the transition (10 ± 3 days before to 42 days after calving). A portion of the total mixed ration (TMR) from the control group (C) was replaced with n-3 PUFA-rich LS in both experimental groups (LS and LS + Se), keeping the diets iso-energetic and iso-nitrogenous. In addition, in the LS + Se group, inorganic sodium selenite was replaced by organic selenium. On day 42, we found (a) higher (P < 0.05) LDL level and Sodium ion concentration in the LS group than in the LS + Se and C groups; (b) lower (P < 0.05) concentrations of triglycerides and lactate in the LS and LS + Se groups than in the C group; and (c) higher (P < 0.05) urea concentration in the LS + Se group than in the C and LS groups. In conclusion, n-3 PUFA supplementation acted positively on lipid profile and no adverse effect on plasma metabolic parameters were found.
The objective of this study was to examine the benefits of different n6/n3 polyunsaturated fatty acid ratios on the lipid metabolism, insulin resistance, and oxidative stress in the adipose tissue of ...rats fed a high-fructose diet. Male and female rats were divided into four groups: a control group (CON) (n6/n3 ratio ~7), a high-fructose group (HF) (n6/n3 ratio ~7), an N6-HF group (n6/n3 ratio ~50), and the DHA-HF group (n6/n3 ratio ~1, with the addition of docosahexaenoic (DHA) and eicosapentaenoic (EPA) acid). The CON group received plain water and the HF group received 15% fructose in their drinking water. Fructose induced an increase in the content of serum triglycerides, serum cholesterol, and HOMA-IR index. Among the fatty acids, elevated proportions of C18:1n9 and C16:1n7, as well as an increase in total monounsaturated fatty acid (MUFA), were found in the adipose tissue of the HF group. Fructose treatment also changed oxidative parameters, including a marked increase in the serum malondialdehyde (MDA) content. Meanwhile, DHA supplementation caused a significant decrease in the serum MDA concentration in comparison with the HF group. In addition, DHA/EPA supplementation attenuated oxidative stress by increasing NRF 2 gene expression. Fructose treatment also significantly decreased the adiponectin level, while DHA supplementation ameliorated it. The changes observed in this trial, including the decrease in the content of DHA and EPA, the decreased EPA/ARA ratio, and the increase in the expression of inflammatory genes, are characteristics of the low-grade inflammation caused by fructose treatment. These changes in the rat adipose tissue could be prevented by dietary intervention consisting of DHA supplementation and a low n6/n3 ratio.
Selenium (Se), an essential trace element for human and animal health, is covalently incorporated into amino acids, acts as a cofactor for antioxidant enzymes, and is involved in the maintenance of ...the immune system. The main goal of this investigation was to show the effect of Se supplementation, at levels slightly higher than the recommended values, combined with natural zeolite clinoptilolite on Se deposition in tissues (muscle and liver) and on the immune and antioxidative status of supplemented growing pigs. The experiment was carried out during a 98 d period on 60 pigs. Pigs were fed a standard feed mixture based on corn and soybean and were divided into four groups, according to the level of dietary selenium supplementation as follows: C-0.3 mg/kg DM organic Se, E1-0.5 mg/kg DM sodium selenite, E2-0.5 mg/kg DM organic selenium; E3-0.5 mg/kg DM organic Se+0.2% zeolite. Higher (
P
< 0.05) selenium concentrations were determined in the muscle and liver in growing pigs fed with higher organic Se in combination with zeolite compared to the lower organic Se concentration. Addition of organic Se increased (
P
< 0.05) Se deposition in muscle and liver compared to the equal amount of inorganic Se (E2 vs. E1). Higher organic Se in combination with natural zeolite addition increases (
P
< 0.05) proportion of pigs' cluster of differentiation (CD)45
+
compared to the same amount of inorganic Se and lower organic Se addition. The proportion of CD45
+
and CD4
+
lymphocytes was higher (
P
< 0.05) in E3 group compared to the other groups. Higher (
P
< 0.05) proportion of CD21
+
lymphocytes were measured in the E2 and E3 groups compared with the other groups. The highest (
P
< 0.01) activity of glutathione peroxidase (GSH-Px) in pig erythrocytes was observed in the E3 group, while higher (
P
< 0.05) activity of glutathione reductase (GR) was in all experimental groups related to the control one. A dietary addition of 0.5 mg/kg DM of organic Se in combination with zeolite (0.2% DM) has increased (
P
< 0.05) Se deposition in liver, muscle, and blood, compared to the dietary addition of 0.3 mg/kg DM of the organic Se.
Milk production intensification has led to several unwanted aspects, such as sustainability issues and environmental pollution. Among these, increased milk outputs that have been achieved over the ...last 70 years have led to several health and pathophysiological conditions in high yielding dairy animals, including metabolic diseases that were uncommon in the past. Increased occurrence of diverse metabolic diseases in cattle and other domestic animals is a key feature of domestication that not only affects the animals' health and productivity, but also may have important and adverse health impacts on human consumers through the elevated use of drugs and antibiotics. These aspects will influence economical and ethical aspects in the near future. Therefore, finding and establishing proper biomarkers for early detection of metabolic diseases is of great interest. In the present review, recent work on the discovery of fitness, stress and welfare biomarkers in dairy cows is presented, focusing in particular on possible biomarkers of energy balance and oxidative stress in plasma and milk, and biomarkers of production-related diseases and decreased fertility.
In this study, we aimed to evaluate the effects of different proportions of red corn rich in anthocyanins on the diet of fattening lambs considering their productive traits, blood metabolic profile, ...and antioxidative status. The research was carried out with 30 Merinolandschaf lambs, 90 days old and weaned. The feed mixture for lambs (n = 10) of the control group contained yellow corn, while in the feed mixture of experimental group I (n = 10), yellow corn was replaced with red corn at 50% (RC50), and in experimental group II (n = 10), yellow corn was 100% replaced with red corn (RC100). An automatic three-part differential haematology analyser was used to determine haematological parameters in whole blood, and biochemical parameters were determined in blood serum using a biochemical analyser. A diet containing red corn did not affect productive traits or the majority of the examined parameters. However, higher blood haemoglobin content, increased aspartate aminotransferase and creatine kinase activity, and decreased glucose and non-esterified fatty acids concentrations were found in the serum of RC100 lambs. These results indicate a positive effect of red corn rich in anthocyanins on the metabolic profile without any changes in the productive traits of lambs.

Increased animal productivity has reduced animal fitness, resulting in increased susceptibility to infectious and metabolic diseases, locomotion problems and subfertility. Future animal breeding ...strategies should focus on balancing high production levels with health status monitoring and improved welfare. Additionally, understanding how animals interact with their internal and external environment is essential for improving health, fitness, and welfare. In this context, the continuous validation of existing biomarkers and the discovery and field implementation of new biomarkers will enable us to understand the specific physiological process and regulatory mechanisms used by the organism to adapt to different environmental conditions. Thus, biomarkers may be used to monitor welfare and improve management and breeding strategies. In this article, we describe major achievements in the establishment of biomarkers in dairy cows and small ruminants. This review mainly focuses on the physiological biomarkers used to monitor animal responses to, and recovery from, environmental perturbations. We highlight future avenues for research in this field and present a timely positioning document to the scientific community.
The addition of oilseeds and their cakes to the diets of lactating dairy goats is an alternative to supplemental feeding, which improves the lipid profile of goat cheeses. The objective of the ...present study was to evaluate the effect of a diet containing extruded linseed or pumpkin seed cake on the fatty acid profile of semi-hard cheese made from goat milk. The research was carried out with 28 French Alpine goats fed the following diets: 1-basal diet based on extruded soybean and soybean meal; 2-basal diet with 90 g/kg DM extruded linseed (ELS); and 3-basal diet with 160 g/kg DM pumpkin seed cake (PSC). Bulk milk from three separated milk tanks at three samplings was used for the manufacture of four traditional semi-hard cheeses from each milk tank at each sampling on the family farm. The ELS and PSC diets increased fat content in the cheese. The ELS feeding increased the proportion of C18:1 c9, C18:2 c9t11, and C18:3 n-3 in cheese and lowered C8:0, C6:0, and C16:0, while PSC resulted in the highest C18:2 n-6 proportions in the cheese. The health-promoting index was the highest in the cheese of ELS. The ELS had a contribution to higher nutritional and health quality of semi-hard traditional goat cheeses, thus representing a food with health-promoting properties.
Dobrobit životinja predstavlja procjenu stanja životinja kojima reagiraju na podražaje iz okoline. Precizna procjena dobrobiti podrazumijeva multidisciplinaran pristup, a suvremen evaluacijski ...protokol uključuje mjerenja na životinjama i mjerenja koja uključuju smještaj, hranidbu i upravljanje farmom. Svrha ovoga istraživanja bila je odrediti varijabilnost biokemijskih i hematoloških pokazatelja, kao i tjelesnu kondiciju, s obzirom na različite bodovne razrede dobrobiti. Istraživanje je provedeno na 145 krava holsteinske pasmine, nasumično odabranih na šest komercijalnih farma mliječnih krava. Kontrolni popis procjene dobrobiti mliječnih krava sastojao se od 70 pitanja prema protokolu CReNBA. Biokemijski pokazatelji u krvi i mliječnoj plazmi određeni su automatskim kemijskim analizatorom Beckman Coulter AU400 (Beckman Coulter, SRNj). Dobiveni rezultati ukazuju da niže koncentracije albumina, triglicerida, željeza i kalcija u krvi imaju krave na lošije ocijenjenim farmama s obzirom na menadžment farme i infrastrukturu. S obzirom na pokazatelje infrastrukturnih karakteristika farme, menađmenta i ukupnu ocjenu farme, koncentracija albumina u mliječnom serumu bila je veća (P<0.05)u krava s lošijom ocjenom. Sedimentacija eritrocita bila je brža na lošije ocijenjenim farmama s obzirom na infrastrukturu farme i ukupnu ocjenu dobrobiti.
Animal welfare (AW) is a term denoting how the animals are coping with the conditions in which they live. A precise welfare assessment assumes a multidisciplinary approach, and modern evaluation protocol incorporates both the animal-based and non-animal-based measures. Due to the different welfare score classes, this study’s objective was to determine the variability of biochemical and hematological parameters, as well as the body condition score. The study was conducted involving 145 Holstein cows, randomly chosen from the six commercial dairy cow farms. The dairy cows’ welfare assessment checklist consisted of seventy items, pursuant to the CReNBA protocol. The biochemical parameters in blood and the milk plasma were determined using the Beckman Coulter AU400 (Beckman Coulter, FRG) automatic clinical chemistry analyzer. The obtained results indicate that the lower albumin, triglyceride, iron, and calcium values were detected in the cows bred on the farms that were ranked lower concerning the farm management and farm infrastructure levels. In the milk plasma, the concentration of albumins was higher (P<0.05) on the farms that were ranked lower concerning the farm management, infrastructure level, and total score scale. Iron concentration was higher (P<0.05) in the cows from the farms ranked lower concerning farm infrastructure and on the farms that were ranked higher concerning the animal level. The erythrocyte sedimentation rate was higher on the farms with worse marks on the farm infrastructure level and total AW score.
