| dc.description.abstract | Background: Dietary fats can alter the deposition and distribution of body fats in ruminants. The deposition and
distribution of body fat play a vital role in the quality of ruminant carcasses and are of great commercial value since
they influence the profitability and consumer acceptability of ruminant meat. The current study examined the
effects of dietary blend of 80 % canola oil and 20 % palm oil (BCPO) on carcass characteristics, meat yield and accretion of
fatty acid (FA) in subcutaneous, omental, perirenal, and mesentery adipose depots and m. supraspinatus (SS) in goats.
Methods: Twenty four Boer crossbred bucks (BW 20.54 ± 0.47 kg) were randomly assigned to diets containing on DM
basis 0, 4 and 8 % BCPO, fed for 100 d and harvested.
Results: Diet had no effect (P > 0.05) on slaughter weight, dressing percentage, carcass and non-carcass components,
meat yield, color, moisture and carotenoid contents and weight of adipose tissues in goats. The proportion of C18:1n-9
and cis-9 trans-11 CLA in the omental, perirenal and SS was higher (P < 0.05) in goats fed 4 and 8 % BCPO compared with
the control goats. Dietary BCPO reduced (P < 0.05) the proportion of C14:0 in the omental, perirenal and mesentery
depots, C18:0 in the perirenal depot, C16:0 in the SS and C16:1n-7 in the SS, omental and perirenal tissues. Dietary BCPO
enhanced the proportion of C18:1 trans-11 Vaccenic and C18:3n-3 in SS and C20:5n-3 in SS and mesentery depot. No
significant changes were found in the FA composition of subcutaneous depot.
Conclusions: Results indicate that dietary BCPO can be utilized to alter the FA composition of adipose tissues without
detrimental effects on carcass characteristics in goats. Nonetheless, dietary BCPO is not an effective repartitioning agent
for body fats in goats. | en_US |
