The effect of early feeding on growth and small intestinal development in the posthatch poult.
Poults with early access to feed in the hatchery or turkey house grew more than those reared under standard commercial practice. During 48 h posthatch, fed poults utilized yolk and exogenous feed to increase BW by 11 g. The small intestine increased from 3.8% of BW at hatch to 8.9% after 48 h. In contrast, BW in feed-deprived poults decreased by 10 g, whereas the small intestine increased sligh...
متن کاملPoult enteritis complex.
Poult enteritis complex (PEC) is a general term that encompasses the infectious intestinal diseases of young turkeys. Some diseases, such as coronaviral enteritis and stunting syndrome, are relatively well characterised, while others, such as transmissible viral enteritis, poult growth depression and poult enteritis mortality syndrome, remain ill-defined. All forms of PEC are multifactorial, tr...
متن کاملThe biosynthesis of biotin in growing yeast cells: The formation of biotin from an early intermediate.
1. Yeast cells grown in the presence of an unknown radioactive biotin vitamer produced by Penicillium chrysogenum incorporated the vitamer into the newly synthesized biotin. 2. The biotin was isolated as the avidin-biotin complex and after hydrolysis the biological activity and radioactivity were shown to be coincidental. 3. The specific activity of the biotin was identical with that of the pim...
متن کاملStructure and Complexation with Biotin and Biotin-Lipid Assemblies
Fourier-transform infrared studies have been carried out to investigate the secondary structure and thermal stability of hen egg white avidin and its complexes with biotin and with a biotinylated lipid derivative, N-biotinyl dimyristoyl phosphatidylethanolamine (DMBPE) in aqueous dispersion. Analysis of the amide I stretching band of avidin yielded a secondary structural content composed of app...
متن کاملBiotin as a growth requirement for Blastomyces dermatitidis.
It is only in the past few years that the vitamin nutrition of the fungi pathogenic to man has been studied intensively. Among the yeast-like forms, Candida albicana was the first shown to require biotin for growth (Burkholder, 1943; Burkholder and Moyer, 1943), and the same requirement was later reported for Hiutoplasma capsulatum (Salvin, 1949a). The first observation of absolute biotin-defic...
