“…This is in agreement with the findings of Hanafy et al (2008), who reported no significant differences in egg shape index, albumen percentage and yolk index with humic acid supplementation across the treatments. The conjugate base of humic acid as used by Macit et al (2009), reported that yolk colour improved with the supplementation of different levels in layer diets, which is similar with the findings of this study but in contrast with the reports of Dobrzañsk et al (2009), that yolk colour did not improve with supplementation of humic acid. In the present study, improved Haugh unit was observed in 0.4% humic acid diet, which is contrary to the findings of Abo-Egla et al (2011) who reported no significant effect of humic acid on 2.0, 4.0 or 6.0 mg of humic acid per kg was added in drinking water.…”

Increasing prevalence of antibiotic resistance due to its indiscriminate use in poultry production is an emerging public health issue. This has prompted research on viable alternatives that will improve production performance of birds. This study was designed to evaluate the effect of humic acid supplemented diets on production performance and microbial load in laying hens. Fifty-four 20-week old Isa brown hens were randomly distributed into three dietary treatments consisted of six replicates with three birds per replicate in a completely randomized design. Treatment 1 was the basal diet (control diet) with no humic acid supplementation while treatments 2 and 3 had the basal diet supplemented with 0.2% humic acid and 0.4% humic acid, respectively evaluated in a 42-day feeding trial. Performance parameters were evaluated. On day 42, the egg quality attributes were measured. Birds were slaughtered and digesta samples from the ileum were collected for microbial load count. Data obtained were analyzed using descriptive statistics and ANOVA at á0.05. Birds fed 0.4% humic acid supplemented diet had the highest final weight (1721g/bird) and weight gain (97.83g/bird). A decrease in weight was observed in birds fed with 0% humic acid (-168.17g/bird) and 0.2% humic acid (-24.17g/bird) supplemented diets. Higher (P < 0.05) yolk height and yolk width were recorded in supplemented diets as compared with the control diet. Lowest yolk colour (2.33) was found in the control diet while highest (4.16) in 0.4% humic acid diet. Similarly, highest (P < 0.05) Haugh unit (78.09) and shell weight (7.83g) were recorded in 0.4% humic acid supplemented diet. Least total 2 heterotrophic count (1.10 x 10 CFU/ml) was recorded in 0.2% humic acid diet while highest 2 total Lactobacilli count (0.23 x 10 CFU/ml) observed in 0.4% humic acid diet.In conclusion, humic acid supplementation up to 0.4% can serve as a viable replacement to antibiotic growth promoter for improved gut health and performance of laying birds. La prévalence croissante de la résistance aux antibiotiques en raison de son utilisation inconsidérée dans la production avicole est un problème de santé publique émergent. Cela a suscité des alternatives viables qui stimuleront la réponse immunitaire des oiseaux et amélioreront les performances de production. Cette étude a été conçue pour évaluer l'effet des régimes alimentaires enrichis en acide humique sur les performances de production et la charge microbienne chez les poules pondeuses. Cinquante-quatre poules brunes Isa âgées de 20 semaines ont été réparties au hasard dans trois traitements diététiques composés de six répétitions avec trois oiseaux par répétition dans un plan complètement randomisé. Le traitement 1 était le régime de base (régime témoin) sans supplémentation en acide humique, tandis que les traitements 2 et 3 avaient le régime de base complété avec 0,2 % d'acide humique et 0,4 % d'acide humique, évalués respectivement dans un essai d'alimentation de 42 jours. Les paramètres de performance ont été évalués. Au jour 42, les attributs de qualité des œufs ont été mesurés. Les oiseaux ont été abattus et des échantillons de digesta de l'iléon ont été collectés pour le décompte de la charge microbienne. Les données obtenues ont été analysées en utilisant des statistiques descriptives et une ANOVA à á 0,05. Les résultats ont montré que les oiseaux nourris avec une alimentation enrichie en acide humique à 0,4% avaient le poids final (1721 g/oiseau) et le gain de poids (97,83 g/oiseau) les plus élevés. Une diminution du poids a été observée chez les oiseaux nourris avec des régimes supplémentés à 0 % d'acide humique (-168,17 g/oiseau) et 0,2 % d'acide humique (-24,17 g/oiseau). Une hauteur et une largeur du jaune plus élevées (P< 0,05) ont été enregistrées dans les régimes supplémentés par rapport au régime témoin. Une couleur plus faible du jaune (2,33) a été trouvée dans le régime témoin alors qu'elle était plus élevée (4,16) dans le régime contenant 0,4 % d'acide humique. De même, une unité Haugh (78,09) et un poids de coquille (7,83 g) plus élevés (P < 0,05) ont été enregistrés dans un régime enrichi en acide humique à 0,4 %. Le nombre total d'hétérotrophes le plus faible (1,10 x 102 cfu/ml) a été enregistré dans un régime contenant 0,2 % d'acide humique, tandis que le nombre total de lactobacilles le plus élevé (0,23 x 102 cfu/ml) a été observé dans un régime contenant 0,4 % d'acide humique. En conclusion, une supplémentation en acide humique jusqu'à 0,4% peut servir de remplacement viable au promoteur de croissance antibiotique pour améliorer la santé intestinale et les performances des oiseaux pondeurs.

“…Those authors also detected a significant increase in the USFA : SFA ratio in meat after 10% HS dietary supplementation. Macit et al (2009) reported an increase in SFA myristic acid and MUFA myristoleic, palmitoleic and heptadecenoic acids in egg yolks of layers fed a HS-supplemented diet. PUFA n-3 and PUFA n-6 levels in egg yolks remained unchanged by HS dietary treatments.…”

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...

“…The most important criterion for a consumer's choice of eggs is the yolk color. Egg yolk color is mainly determined by carotenoids and other pigmented substances —laying hens do not biosynthesize them— in the feed ( Macit et al, 2009 ). Lutein in carotenoids is absorbed by laying hens and deposited in eggs.…”
