After about three weeks of feeding, they drop off into the soil to pupate.
After 12 weeks of feeding, all fish were sampled for weight measurements.
Muscle gross composition, lipid class and fatty acid composition and astaxanthin were measured at the start and after 22 and 42 weeks of feeding.
The effects of the diets on performance, fat digestibility, muscle and liver fatty acid composition were determined after 12 weeks of feeding.
The effects of the diets on plasma metabolites, the activity of selected enzymes involved in lipid metabolism, biometric indices and muscle glucose transporter GLUT4 expression were determined after 12 weeks of feeding.
After about six weeks of feeding, the parent birds desert their young, which then waits alone until it becomes thin and its flightfeathers have grown, and then it flies out to sea by itself.
A minimum of 9 weeks of feeding with xanthophylls is necessary for proper pigmentation of the Arctic char.
However, the maximum uptake of carotenoids occurs after 15 weeks of feeding with diets enriched in xanthophylls (Shahidi et al. 1994).
Different levels of dietary soybean meal (SBM) as a fish meal (FM) replacer, with and without amino acid supplementation, for whiteleg shrimp, Litopenaeus vannamei reared in the biofloc system was examined in eight weeks of feeding trial.
After 3 weeks of feeding, the larva secretes a hard brown shell around itself--a pupa--and spends 18 to 24 hours as anatomical soup, breaking down and remodeling everything from its digestive tract to its central nervous system.
As a result, 2 weeks of feeding significantly reduced hepatic lipids, though hyperinsulinemia evidently still remained.
