Summary: The objective of this study was to compare the effects of commercial yeast products in layer hen diets on egg production parameters and the cecal microbiota composition. A short-term feeding trial was conducted with 35 laying hens receiving either a control or one of four different yeast fermentation products. The results showed that the yeast products had little effect on egg production and shell quality, and only moderately impacted the composition of the cecal microbiota in mature layer hens.

Summary: A group of six amino-hypophosphite polyampholytes (AHPs) were synthesized and tested for their ability in scavenging four toxic metal ions. The AHPs were produced using a green and convenient one-pot reaction, making them more sustainable than conventional materials derived from crude oil. Characterization using FTIR spectra showed that the AHPs possessed ion scavenging properties in a wide pH range, with certain selectivity towards specific metal ions. The high ionic capacities of the AHPs suggest their potential application in removing toxic metal ions from various types of wastewater.
