Chinese herb ultrafine powder supplementation improves egg nutritional value and quality in laying hens
This study evaluates the effects of dietary Chinese herb ultrafine powder (CHUP) supplementation in late-phase laying hens on the quality and nutritional values of eggs. A total of 576 Xinyang black-feather laying hens (300-day-old) were randomly allocated into eight groups for a 120-day feeding trial. Each group contained eight replicates with nine hens per replicate. The experimental groups included the control (basal diet) and different levels of CHUP groups (details in 'Materials and methods'). The results showed that the eggshell strength was increased (p < 0.05) in the L, LF, L-LF, L-T, and LF-T groups on day 60 o...

The kinetics of goat sperm is negatively affected after freezing in an extender including zinc oxide nanoparticles
CONCLUSION: The addition of Np-ZnO (200 ug/mL) to the goat semen freezing extender improved the total motility of cells, whilst negatively affecting sperm kinetics. https://doi.org/10.54680/fr24210110512.PMID:38557988 (Source: Cryo-Letters)

Cold-induced damage in boar sperm cooled to 5 °C in Lactose Egg Yolk (LEY) medium with different Glycerol concentrations
Anim Reprod Sci. 2024 Mar 13;264:107455. doi: 10.1016/j.anireprosci.2024.107455. Online ahead of print.ABSTRACTBoar sperm is highly susceptible to cold damage. When temperature drops to 5°C, the plasmatic membrane is destabilized. The freezing process causes a reduction of the fertility window because frozen/thawed boar sperm has less survivability. The aim of this work was to analyze the effect on sperm characteristics and response to capacitation stimuli of cooling to 5°C using a controlled protocol. Also, we evaluated if the addition of Glycerol 2% or 3% at 5°C was able to modify these parameters. For this purpose, w...
