“…Although the precise underlying mechanism of the effect of humic substances is unknown, it appears that humic substances contains minute quantities of several minerals, including Fe, Mn, and Cu, which may influence meat colour [33]. The observation that meat of broilers fed the control diet had the greatest WHC is in concordance with findings from other studies [34–36]. Although diet had no effect on both drip loss and cooking loss, it has been observed that, generally, greater drip loss may induce a reduction in water-holding capacity and tenderness of meat [12,37].…”

“…Chang et al confirmed that different doses of FA reduced pig backfat, and found that this was due to a higher activity of hormone sensitive lipase (HSL) and lower activity of lipoprotein lipase (LPL) [ 58 ]. Bai et al reported that dietary supplementation FA could increase G/F and reduce backfat thickness and malonaldehyde (MDA) in growing–finishing pigs [ 59 ]. Supplementation with sodium humate was also found to increase the digestibility of crude protein and crude fat in growing pigs; the resultant decrease in N-containing substances, in particular, could help decrease ammonia emissions [ 60 , 61 , 62 ].…”

Reduction of antibiotic use has been a hot topic of research over the past decades. The European ban on growth-promoter use has increased the use of feed additivities that can enhance animal growth performance and health status, particularly during critical and stressful phases of life. Pig farming is characterized by several stressful periods, such as the weaning phase, and studies have suggested that the proper use of feed additives during stress could prevent disease and enhance performance through modulation of the gastrointestinal tract mucosa and microbiome. The types of feed additive include acids, minerals, prebiotics, probiotics, yeast, nucleotides, and phytoproducts. This review focuses on commonly used acids, classified as inorganic, organic, and fatty acids, and their beneficial and potential effects, which are widely reported in the bibliography. Acids have long been used as feed acidifiers and preservatives, and were more recently introduced into feed formulated for young pigs with the goal of stabilizing the stomach pH to offset their reduced digestive capacity. In addition, some organic acids represent intermediary products of the tricarboxylic acid cycle (TCA), and thus could be considered an energy source. Moreover, antimicrobial properties have been exploited to modulate microbiota populations and reduce pathogenic bacteria. Given these potential benefits, organic acids are no longer seen as simple acidifiers, but rather as growth promoters and potential antibiotic substitutes owing to their beneficial action on the gastrointestinal tract (GIT).

“…ZnO is well known to enhance growth performance in piglets through the stabilisation of the intestinal microbiota and improvements in nutrient digestion and utilisation. HS may benefit animal performance even though the actual mechanism is not fully understood (Kim et al 2004;Ji et al 2006;Bai et al 2013).…”

“…Weber et al (2014) suggested that HS in the diet of young pigs (0.25% for 35 days) may play a role in negating the effects of oxidative stress within the body. The inclusion of HS in the diets of broilers and growing pigs was found to reduce lipid peroxidation in muscle tissues during storage which had a positive effect on meat quality (Aksu et al 2005;Bai et al 2013). The in vitro study of Vaskova et al (2011) showed a decrease in the activity of superoxide dismutase; however, activities of other antioxidant enzymes were not influenced after HS treatment and HS-supported generation of ROS was not observed.…”

ABSTRACT:The aim of this study was to investigate the effects of sodium humate (HNa), applied to feed or drinking water as a partial substitution for pharmacological doses of ZnO, on clinical, biochemical and haematological indicators of health status, oxidative stress and the serum fatty acid (FA) profile in weaned piglets. Weaned piglets (32) were allocated into four groups: Control = basal diet containing 110 mg ZnO/kg; ZnO 2.5 = pharmacological dose of ZnO (2.5 g ZnO/kg); ZnO 1.7 + HNa (f ) = 1.7 g ZnO and 20.0 g HNa/kg; ZnO 1.7 + HNa (w) = 1.7 g ZnO/kg and drinking water with 0.2% HNa. All ZnO treatments resulted in good performance and clinical health of piglets in contrast to Control, which contained three diarrhoeic piglets. Increased triacylglycerols in the ZnO 2.5 and ZnO 1.7 + HNa (w) groups in comparison with Control suggested increased energy metabolism after treatments. Neither total cholesterol, nor HDL and LDL were affected by treatments. Piglets treated with ZnO and HNa had (ZnO 1.7 + HNa (w)) or tended to have (ZnO 1.7 + HNa (f )) lower urea in serum. Significantly (in ZnO 2.5 and ZnO 1.7 + HNa (f )) or non-significantly (ZnO 1.7 + HNa (w)) higher haematocrit and haemoglobin levels were detected in the blood of treated piglets. Long-term ZnO 2.5 treatment significantly increased serum 8-iso-PGF 2α , the most reliable biomarker of oxidative stress. Partial substitution of ZnO by HNa positively affected the oxidative status of piglets as evidenced by significant (ZnO 1.7 + HNa (w)) or non-significant (ZnO 1.7 + HNa (f )) declines in serum 8-iso-PGF 2α . ZnO 2.5 treatment significantly decreased saturated (SFA), monounsaturated (MUFA) and n-3 polyunsaturated FA (PUFA) and increased PUFA n-6 and n-6/n-3 ratios in serum compared to Control. The synthesis of some physiologically significant long-chain PUFA (LC-PUFA), namely n-6 dihomo-γ-linolenic acid and n-3 eicosapentaenoic, docosapentaenoic was negatively affected by ZnO 2.5 treatment. Both ZnO 1.7 + HNa (f )/(w) treatments significantly increased the proportion of SFA and PUFA n-3 and decreased PUFA n-6 and n-6/n-3 ratios in comparison with ZnO 2.5 and the effect was more considerable in ZnO 1.7 + HNa (w). Most individual PUFA n-3 and n-6 as well as the n-6/n-3 ratio in both treatments were similar to Control. The results indicate that the partial substitution of ZnO by HNa can benefit performance and health of weaned piglets to a similar extent as a high pharmacological dose of ZnO, whereas it can decrease the oxidative stress induced by prolonged over-supplementation of ZnO. Additionally, such a treatment can eliminate the unfavourable effect of high ZnO doses on the n-6/n-3 ratio and the proportion of some physiologically significant LC-PUFA in serum. Generally, it can be concluded that the effects of feed and water HNa supplementation are similar, but are more pronounced when HNa is applied to drinking water.Keywords: humic substances; pig; lipid metabolism; eicosanoids; serum biochemistry; haematology; performance; GC/MS; LC/MS-MS List of ab...
