Effects of Dietary Supplementation of Natural Pigments on Egg Yolk Color in Laying Hens.
Japanese poultry science, 1994 産卵開始後約8ヵ月経過した産卵鶏に対して,コーングルテンミール(CM),マリーゴールド花弁粉末(MM),パプリカ粉末(PM)およびパプリカ抽出処理物(PE)の4種類の天然卵黄着色強化剤を20日間投与し,卵黄の着色効果を比較検討した。その結果,すべての着色強化剤は無添加対照区に対して,ロシュのヨークカラーファン値(RCF値)を有意に高め卵黄に対する着色効果を認めた。しかしながら,飼料中のキサントフィルを同量にしたにもかかわらず,RCFは赤色色素に対する感応が強いため,飼料中の黄色系キサントフィルの多いCMとMMは,赤色系キサントフィルを多く含むPMおよびPEよりも,RCF値を高めることはできなかった。色差計によるイエローインデックス(YI)および赤色度(a値)は,RCF値と同じ傾向が見られ ...

, 2010 Nowadays, intensely farmed poultry eggs show almost no differences in egg yolk and albumin compared with domestic layers. Annatto shrub grows rapidly to produce seeds coated with bixin and norbixin dyes which are used to color foods requiring no limits ...

Axial muscle‐fibre orientations in larval zebrafish
Journal of Anatomy, Volume 246, Issue 4, Page 517-533, April 2025.In 4 days post‐fertilization zebrafish larvae, the fast axial muscle fibres follow helical trajectories that taper towards the tail. Adjacent muscle fibres form substantial angles relative to each other to accommodate this pattern. Using a novel semi‐automatic method, we quantified 3D fibre angles over the whole muscle volume.

Development of the abdominal musculature in the chicken embryo
Journal of Anatomy, EarlyView.In this study, we investigate anatomy, morphogenesis, segmental origin, and fiber formation of the abdominal musculature in the chicken embryo. We show that abdominal muscles arise from somites 24 to 28, and that the segmental identity of individual fibers in the abdominal muscle sheets is maintained.

Alternative Protein Sources in Poultry and Pig Nutrition—A Review
Journal of Animal Physiology and Animal Nutrition, EarlyView.ABSTRACT Proteins are an essential nutrient for the viability of all animals, enabling organisms to grow, regenerate and defend themselves against pathogenic organisms. Soybean and soybean‐based materials are commonly used to supplement protein in animal nutrition.

Journal of Zoology, EarlyView.Here we explore the effects of elevated water conductivity on larval eastern hellbenders (Cryptobranchus a. alleganiensis), both lethal and sublethal. We found that elevated water conductivity significantly impacts both survival and morphology, though it has limited effects on locomotor performance, stress physiology, and oxidative stress.
