Utilization of mannan oligosaccharides as antibiotic substitutes in laying hens.

Among global concerns about antibiotic resistance, it is necessary to identify food-safe alternatives to enhance production. This study aimed to evaluate the impact of mannan oligosaccharides (MOS) inclusion to replace antibiotic growth promoters (AGP) in the diets of ISA Brown laying hens aged between 23 and 31 weeks. Two hundred forty hens were grouped into five treatments: Control, AGP (130 ppm of enramycin 8.

Effects of Extract as a Feed Additive on Digestibility and Performance of Hair Lambs.

Animal production requires efficiency, safety and environmental sustainability. Bioactive compounds from tropical plants could modulate ruminal fermentation, providing an alternative method to antibiotic treatment and addressing concerns about antibiotic resistance. In this study, the aim was to determine the effects of extract (TDE) on performance, intake, digestibility and blood parameters [i.

Assessing the In Vitro and In Vivo Effect of Supplementation with a Garlic () and Oregano () Essential Oil Mixture on Digestibility in West African Sheep.

This study assessed the impact of a mixture of garlic () and oregano () essential oils (EOGOs) on in vitro dry matter digestibility (IVDMD) and in vivo apparent nutrient digestibility. Different EOGO inclusion levels were evaluated to assess the dose response and potential effects of the mixture. Three EOGO inclusion levels (0.
