“…The production method of highly marbled beef can be facilitated by advancing the productivity of beef cattle fattening. Several factors, including breed (Malau-Aduli et al 1999), length of the fattening period (Okumura et al 2007b) and type of grain fed (Yamada et al 2008), affect the degree of marbling or proportion of intramuscular fat. Vitamin A (VA) restriction in feed for beef cattle also improves marbling (Oka et al 1998); thus, restricting dietary VA and the precursor carotenoids is effective in improving beef quality.…”

Vitamin A (VA) restriction in beef cattle improves meat marbling; however, the underlying molecular mechanisms remain incompletely understood. We performed microarray analysis to clarify the effect of VA restriction on Longissimus thoracis gene expressions in Japanese Black steers. Six Japanese Black steers 13-14 months of age were divided into two groups: S group (n = 3), which received VA supplementation, and R group (n = 3), in which dietary VA intake was restricted. Steers were fattened for 7 months, following which tissue samples were obtained. Extracted RNA samples were analyzed by Affymetrix Genechip Bovine Genome Array. Lists of genes highly expressed in the R and S groups were obtained. The lists were functionally interpreted using functional annotation software, DAVID. In the R and S groups, 48 and 40 genes were significantly highly expressed, respectively. The gene list of the R group included CD36, LPL, GPAM, DGAT2, and SCD and additional genes annotated 'PPAR signaling pathway,' 'lipid biosynthesis' and 'mitochondrion,' whereas that of the S group included COL1A2, FN1 and DCN and additional genes annotated 'extracellular matrix.' Changes in the expression of these genes are possibly involved in marbling improvement in beef cattle by VA restriction.
