Quantification of Japanese quail eggshell colour by image analysis.
The Japanese quail lays eggs with colourful and patterned shells which make the eggshell colour difficult to classify. In this study, the method of measuring colour of patchy eggs using image analyses and its power to discriminate among individual variation were established. Estimated repeatability for egg colour and proportion of patterned areas was high (>0.58), suggesting intermedíate or hig...
متن کاملLaying performance and eggshell quality in laying hens fed diets supplemented with prebiotics and organic acids
The aim of the study was to evaluate the effect of organic acids and the prebiotic fructans on egg production and eggshell quality when added to the layer diet with different levels of calcium and phosphorus. The experiment was carried out on 168 Bovans Brown hens, allocated to 14 groups of 12 replications. Each hen (replication) was kept in an individual cage 40 cm × 40 cm in size. A 2 × 7 fac...
متن کاملHistological and fatty acids changes in Caspian salmon (SalmotruttacaspiusKessler, 1877) fed diets with different levels of vitamins E and highly unsaturated fatty acids (HUFA)
In this study, the combined effect of different levels of dietary n-3 HUFAs with α-Tocopherol on changes in the structure of intestine and pyloric caeca and fatty acids profile of Caspian salmon, Salmotrutta caspius, fry (initial weight of 600 ± 25 mg for 10 weeks) were investigated. Six experimental diets containing three different dietary levels of n-3 HUFAs (Low: 1 + 0.5, DHA+ EPA, Med...
متن کاملGlucose, amino acids, and lipogenesis in hepatocytes of Japanese quail.
Hepatocytes were isolated from livers of fed, egglaying Japanese quail (Coutournix mutournix j u p n ica). The cells take up and extensively oxidize lactate and pyruvate and, to a lesser extent, fructose, glycerol, sorbitol, and xylitol. The major products were COZ, glucose, and lipid. Lactate was the best substrate for fatty acid synthesis. Glucose at a concentration of 10 IUM was taken up and...
متن کاملEarly life stress shapes female reproductive strategy through eggshell pigmentation in Japanese quail.
Physiological constraints on colouration have been widely reported; especially in birds, which trade-off antioxidant responses against colourful costly signals. One female extended phenotypic trait, which might also highlight important physiological trade-offs, is the pigmentation of their eggshells. In ground-nesting species, producing eggs that are visually undetectable by predators is the be...
