The effect of different commercially available bedding materials on the growth performance and carcass characteristics of ducks for 42 days was investigated. 336 one-day-old White-Pekin ducklings (60.48 ± 0.16 g) were randomly allocated into 24-floor pens with one of the three beddings namely i) coco peat, ii) rice husks, or iii) sawdust. 14 ducklings per pen and 8 replicate pens per bedding material were used. Birds were fed a starter diet from days 1-21 and a grower diet from days 22-42. Weekly growth performance evaluation was conducted for the average body weight, weight gains, daily feed intake, and feed conversion efficiency. One bird per pen was sacrificed on day 42 for the evaluation of carcass characteristics including the carcass, breast, and leg muscle percentages. Breast and leg muscle samples were then collected and analyzed for their proximate and pH values. Higher body weights (p < 0.05) were noticed with rice husks on day 42 only. Improved daily gains ( < 0.05) were also noticed for birds raised with rice husks over the entire period (days 1-42). Concerning feed intake, higher values ( < 0.05) were similarly noted with rice husks for the grower phase (days 22-42), and the entire experimental period (days 1-42). Marginally improved feed intake values were also noted with the use of rice husks as the bedding materials on day 42 ( = 0.092). Improved feed efficiency ( < 0.05) was noticed with rice husks on day 35, the grower period, and the entire 42-day period. However, no significant differences were noticed for most of the carcass characteristics that were evaluated. Nevertheless, higher ( < 0.05) pH values for the breast muscle were noticed with the use of coco peat and sawdust as the bedding. Conclusively, the bedding type could have a significant impact on the growth performance of ducks without adverse effects on carcass characteristics. The use of rice husks as bedding might be advantageous and is therefore recommended.

This study investigated the spatial distribution of Cd and mineral nutrients (Mg, P, K, Ca, Mn, Fe, Cu, Zn) in rice grains from low-Cd accumulating (LA) and high-Cd accumulating (HA) cultivars using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Cd concentrations were significantly higher in HA than LA cultivars across polished rice, brown rice, and husks. Spatial mapping demonstrated Cd was distributed in the outer endosperm/embryo of LA grains, but preferentially enriched in the embryo and aleurone layer of HA grains.

This research demonstrates the potential of plant waste cellulose as a remarkable biomaterial for multilayer tablet formulation. Rice husks (RC) and orange peels (OC) were used as cellulose sources and characterized for a comparison with commercial cellulose. The FTIR characterization shows minimal differences in their chemical components, making them equivalent for compression into tablets containing ibuprofen.

More than one billion tons of chaff waste are generated globally every year, but traditional recycling methods face the dual challenges of inefficiency and environmental risks, to solve this problem, this study innovatively achieves the dual functions of lignocellulosic synergistic degradation and plant promotion by constructing synthetic microbial communities. Firstly, a cellulose-degrading bacterium cmk-7 (Chromobacterium violaceum) was screened from soil based on Congo red staining method, and the maximum values of CMCase enzyme activity and FPase enzyme activity were 289.12 U/mL and 332.

Calcium (Ca) enrichment in rice grain is crucial for ensuring grain yield and quality. Thus, it is vital to understand the transport pathways of Ca from the soil to grain. In the present study, Ca isotope ratios were determined using pot experiments to elucidate the pathways of Ca transportation from soil to rice grains during grain filling.

The unique flavor profile of Nongxiangxing baijiu is intricately linked to its interlocking brewing processes. However, limited research exists on how the raw grains used in brewing affect baijiu's flavor through the simultaneous distillation of raw and fermented materials. This study used Simultaneous Distillation Extraction coupled with Gas Chromatography-Mass Spectrometry to analyze the flavor composition of five brewing materials and one brewing adjunct: sorghum, rice, maize, millet, wheat, and rice husks-after steaming and the flavor quality of the crude baijiu produced through different brewing techniques.
