“…Supplementing animal feeds with non-nutritive adsorbents as humic acid has proven to substantially reduce mycotoxicosis (Sabater-Vilar et al, 2007) and improved the performance, carcass, GIT and meat quality traits (Ozturk et al, 2011). In our study, the mortality was negligible with no difference between control and humic acid-treated group.…”

Glyphosate (N-(phosphonomethyl) glycine) is a most popular herbicide in agricultural practices throughout the world. It is possible that glyphosate spread in the ecosystems can reach plants, animals. The present work was directed to investigate the glyphosate residue in different organs of broiler chickens using ELISA and to study the possibility of its neutralisation using humic acid, Chlorella vulgaris and Saccharomyces boulardii. Results showed that glyphosate residues could be detected in the animal feed and different organs as liver, spleen, lung, intestine, heart, muscles and kidney. Humic acid, Chlorella vulgaris and Saccharomyces boulardii showed neutralization of the antimicrobial effect of glyphosate in vitro. Also, feed supplementation of commercial broiler with humic acid (0.2%) leads to a significant decrease in the glyphosate content, i.e. by 53%, 28%, 44%, 50%, 56%, 16%, 63% and 0% in serum, liver, spleen, lung, gastro-intestinal tract, heart, muscles and kidney, respectively. There were no significant effects of humic acid on the production parameters. This enlightenment will help to overcome the negative effect of glyphosate residues on gastrointestinal microbiota and protect consumers from glyphosate residues in chicken meat.

“…The 17.5% canola inclusion was the maximum rate possible for formulation of a balanced broiler diet, while the inclusion level of enzymes was the recommended level provided by feed companies for ingredients such as canola, which are poor protein sources that contain high fibre. The inclusion level of potassium humate was derived based on the ranges from the literature (Ozturk et al, 2012;Ragaa & Korany, 2016). Ingredients and dietary formulae are shown in Table 1, and Table 2 shows the nutritional compositions of the diets.…”

The objective of the study was to investigate the effects of dietary inclusion of humic acid and enzymes on bone development, histomorphology of internal organs and the incidence of rickets in broiler chickens fed canola-based diets. In the study, Cobb 500 broiler chicks were used and the following five dietary treatments were administered: control (commercial diet); CM (17.5% canola meal inclusion); CMEnz (17.5% CM inclusion + 0.3g/kg Axtra XAP); CMPh (17.5% CM inclusion + 1.5% potassium humate (PH)); and CMEnzPh (17.5% CM inclusion + 1.5% PH + 0.3g/kg Axtra XAP). These diets were formulated and randomly allocated to 20 pens (experimental units), each housing 11 birds. The birds were phase fed, with the starter diet being given to all birds from day 1 to day 14. During the grower (days 15-28) and finisher phases (days 29-42) birds were fed the experimental diets. Diet differed significantly across all treatments on latency-to-lie (LTL) test. Broilers fed CMEnz had the lowest standing persistence (2.88 ± 2.69 min) and those on CMEnzPh had the highest (11.19 ± 2.69 min), followed by those offered the control diet (9.05 ± 2.69 min). Gross lesion analysis displayed high prevalence of rickets in boilers fed CMEnz diet compared with all other dietary treatments. Intestinal morphometric parameters demonstrated some dietary differences in the height and width of the intestinal villi and intestinal crypts. In conclusion, inclusion of humic acid in canola-based diets appeared to positively influence digestion and assimilation dynamics that were consequential to the improvement in bone and immune development in broilers. ______________________________________________________________________________________

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...
