Addition of Different Levels of Humic Substances Extracted from Worm Compost in Broiler Feeds

Different sources and inclusion levels of humic substances (HS) have been tested in broiler rations as an alternative to the addition of growth promoter antibiotics (GPA) with promising results. The current study was carried out to assess the influence of HS extracted from worm compost on broiler pr...

The current study was carried out to assess the influence of HS extracted from worm compost on broiler production parameters, carcass yield, tibia characteristics, lactic acid bacteria (LAB) counts, excretion of <i>Eimeria</i> oocysts, and antioxidant status of breast meat. A total of 1200 broilers were used, housed in groups of 30 per pen, and assigned to five treatments: 1 = basal diet with GPA (positive control), 2 = basal diet without GPA (negative control), 3–5 = basal diet with 0.15, 0.30, and 0.45% HS, respectively. The data was subjected to a variance analysis and orthogonal contrasts. The FI decreased linearly (<i>p <</i> 0.05) from 1–14, 29–42, and 1–42 days as the inclusion of HS in the feed increased. The FCR had quadratic responses (<i>p <</i> 0.01) from 29–42 and 1–42 days concerning the HS inclusion levels. Lactic acid bacteria was higher (<i>p ˂</i> 0.05) in ten-day-old chicks with 0.45% HS in the diet. The 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity antioxidant potential decreased linearly (<i>p <</i> 0.05) concerning increasing HS in the feed. The results indicate that HS can be used as growth promoters in broiler feeds.Alejandra Domínguez-NegreteSergio Gómez-RosalesMaría de Lourdes AngelesLuis Humberto López-HernándezTercia Cesaria Reis de SouzaJuan David Latorre-CárdenasGuillermo Téllez-IsaiasMDPI AGarticlebroilersperformancehumic substanceslactic acid bacteriaantioxidantVeterinary medicineSF600-1100ZoologyQL1-991ENAnimals, Vol 11, Iss 3199, p 3199 (2021)
