Global Poultry Feed Protein Sources: Trends, Challenges, and Sustainability Perspectives Using FAOSTAT Data

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT The global poultry industry is one of the fastest‐growing livestock sectors, with worldwide chicken stocks exceeding 32 billion heads and meat production surpassing 144 million tonnes in 2024 (FAOSTAT, 2026). Conventional protein sources, particularly soybean meal (SBM) and fishmeal, underpin most commercial poultry diets but face mounting ...

Combination of In Ovo Nutritional Components Improves Embryonic Development, Growth Performance, and Gut Health in Broiler Chickens

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study evaluated the effects of intra‐amniotic administration of combined energy, amino acid, and vitamin sources on embryonic development, post‐hatch growth performance, and intestinal health in broiler chickens. On Day 18 of incubation, 460 fertile Ross 308 eggs were allocated to four groups: non‐injected negative control (NC), saline ...

Studies on egg yolk pigmentation. 3. The effect of origin and storage conditions of yellow corn on the utilization of its xanthophyll.

open access: yesPoultry Science, 1967
VARIOUS yellow corn inbreds contain different levels of xanthophyll (class term, for oxygen-containing carotenoids), as well as different ratios between the various carotenoids making up their total xanthophyll (Quackenbush et al., 1961, 1963; Blessin et

Intraspecific Variation in Reproductive Aspects of Female Soldier Crabs, Mictyris guinotae, Between the River Mouth and Upper Reach Habitats

open access: yesMarine Ecology, EarlyView.
ABSTRACT The soldier crab, Mictyris guinotae, is a dominant intertidal crustacean associated with sand flats in the vicinity of the Urauchi River estuary on Iriomote Island, Japan. We compared various aspects of its reproductive biology at two sites (the river mouth and upper reach) on exposed bare sand flats 300 m and 3000 m upstream from the mouth ...

In Transected Nerves, Distal Repair Schwann Cells at the Injury Site Direct and Accelerate Axonal Regrowth

open access: yesGlia, Volume 74, Issue 10, October 2026.
After nerve transection in larval zebrafish, proximal and distal Schwann cells have distinct functions at the injury site. Distal repair Schwann cells promote axonal regrowth. Axonal regrowth is normal in mutants with only a few macrophages. ABSTRACT In vertebrate peripheral nerves, damaged axons can regrow after injury, but the outcomes of ...

Influence of a Xanthophyll-Free Pullet Grower Diet on Subsequent Egg Yolk Pigmentation

open access: yes, 1974
Two experiments were conducted to determine the importance of xanthophyll in the diet of growing egg-type pullets. The experiments were designed so that both the rate of xanthophyll depletion from the body and the amount of xanthophyll deposited in the ...
