Effects of dietary inclusion of palm kernel cake and palm oil, and enzyme supplementation on performance of laying hens. [PDF]

open access: yes, 2008
A total of 392 twenty eight week-old laying hens was used to study the effects of dietary inclusion of solvent extracted palm kernel cake (PKC) (0%, 12.5% and 25%) and enzyme (mixture of mannanase, α-galactosidase and protease) supplementation (0 kg/t, 1

4D Insights into Coral Biomineralization: Effects of Ocean Acidification on the Early Skeleton Development of a Stony Coral

open access: yesAdvanced Science, EarlyView.
Early coral skeletons grow through formation of two co‐joined zones, rapid accretion deposits and thickening deposits. Advanced imaging and simulations reveal that ocean acidification reshapes these zones, shifting the coral portfolio of mineral phases which alters skeletal resistance to mechanical stress.

Insect I‐Type Lysozymes Function as Antiviral Proteases by Forming Biomolecular Condensates

open access: yesAdvanced Science, EarlyView.
Upon rice viral infection, the insect vector activates the Toll–MyD88–Dorsal signaling cascade, inducing i‐type lysozyme (Lyz‐I1) expression. Lyz‐I1 functions as an antiviral protease through its conserved catalytic dyad Glu/Asp (E/D), mediating cleavage of viral proteins at specific Lys (K) residues.

Gradual Provision of Live Black Soldier Fly (Hermetia illucens) Larvae to Older Laying Hens: Effect on Production Performance, Egg Quality, Feather Condition and Behavior

open access: yesAnimals, 2020
Feather pecking is a key welfare challenge in laying hen husbandry. Feeding of live Hermetia illucens larvae could provide a possible solution to reduce feather pecking in hens. This research investigates effects of dispensing live H.

U.S. Consumer Preferences for Cage‐Free Eggs and Hen Housing Policies

open access: yesAgribusiness, EarlyView.
ABSTRACT Farm animal welfare (FAW) continues to be a divisive issue in the egg industry. In the United States, 10 states and most major retailers have implemented policies or voluntary pledges to transition to 100% cage‐free egg sales. We use best‐worst scaling and discrete choice experiments to evaluate U.S.
