Early Post-Hatch Nutrition Influences Performance and Muscle Growth in Broiler Chickens.

The poultry industry is under pressure to produce safe and good quality meat in the welfare conditions. Many areas such as genetics, biosecurity, and immunoprophylaxis were improved, and hatchery is one of the areas in which welfare could be improved for better production output. The aim of the study was to investigate the effect of early post-hatch nutrition providing body weight and muscle development in broiler chickens.

Iridophoroma associated with the Lemon Frost colour morph of the leopard gecko (Eublepharis macularius).

The Lemon Frost is a new colour morph of the leopard gecko, which emerged in ca. 2015 as a result of selective breeding and spontaneous mutation. According to multiple breeders observation of Lemon Frost inbreeding with wild-type leopard geckos, Lemon Frost seems to be a codominant trait.

Histology and ultrastructure of the integumental chromatophores in tokay gecko () (Linnaeus, 1758) skin.

This paper describes the relationship between the arrangement of dermal chromatophores in tokay gecko () skin and the formation of wild-type colouration, with emphasis on the ultrastructure of chromatophores. The samples of the tokay gecko skin were collected from wild-type colouration adult specimens. Morphology and distribution of chromatophores was determined by using light microscopy and transmission electron microscopy.
