ABSTRACT The objective of this study was to evaluate the effect of different sources of choline in the diet of laying Lohmann Brown hens (26 to 37 weeks of age) on productive performance, egg quality, and blood parameters. A completely randomized experimental design was adopted, consisting of five treatments, with eight replications and six birds per experimental unit. The treatments consisted of a basal diet without supplementation of any source of choline (NC); NC + supplementation with 939 mg/kg choline […]

ABSTRACT In this study, our goal was to clarify the role of proteasomal subunit α-1 (PSMA1) in both the differentiation of preadipocytes and the accumulation of lipids in adipocytes. Preadipocytes from healthy one-day-old calves were collected, isolated, and cultured in vitro. The expression pattern of the PSMA1 gene was explored during the differentiation of bovine preadipocytes firstly. Then, the expression of the PSMA1 gene was inhibited by transfection of a chemically synthesized small interfering RNA (siRNA) before differentiation. After induction […]
