Abstract:
... World meat production must increase substantially to support current projections in population growth over the next 30 years. However, maximizing product quality remains a focus for many in the meat industry, as incremental increases in product quality often signal potential increases in segment profitability. Moreover, increases in meat quality also address concerns raised by an ever-growing affl ...

MicroRNA (miRNA) is an endogenous non-coding RNA that can play a role in the post-transcriptional regulation of mammalian preadipocyte differentiation. Previously, we identified that bta-miR-130a regulates milk fat biosynthesis by targeting PPARG mRNA. However, the role of mi ...
