Abstract

Abstract: Yucca schidigera extract (YE) can decrease ammonia concentration in livestock housing, which could be associated with the inhibition of urease. The aim of this study was to investigate the other possible reasons of dietary YE supplementation reducing nitrogen emission in weaned piglets. A total of 14 crossbred weaned barrows were allotted into two groups fed the diets supplementing 0 and 120 mg/kg YE for 14 days. The YE administration decreased F/G ratio and hindgut NH3 ‐N production in weaned piglets ( p < 0.05). Dietary YE supplementation decreased serum urea nitrogen levels, and increased nutrient digestibility, which could be related to the improvement of morphology, digestive and absorptive enzyme activities, and nutrient transporter mRNA expression in jejunal mucosa of weaned piglets ( p < 0.05). The mRNA expression of tight junction proteins, mucins and apoptosis‐related genes was also improved by YE treatment in jejunal mucosa of weaned piglets ( p < 0.05). In addition, dietary YE supplementation regulated the microbiota structure and volatile fatty acid content in distal intestine of weaned piglets ( p < 0.05). These results suggest that YE administration can decrease hindgut NH3 –N production in weaned piglets, which is associated with the increased nutrient utilization and gut‐barrier function.
