Ruminant products are significant sources of dietary trans fatty acids. Trans fatty acids, including various conjugated linoleic acid isomers, have been shown to act as metabolic modifiers of lipid metabolism. Trans fatty acids originate from biohydrogenation of dietary unsaturated fatty acids by gut microbes; however, the exact synthetic pathways are unclear. It was our goal to examine the bio...

Kernel processing and theoretical length of cut (TLOC) whole-plant corn silage (WPCS) can affect feed intake, digestibility, performance dairy cows. The objective this study was to evaluate for lactating cows the effects kernel TLOC WPCS with vitreous endosperm. treatments were a pull-type forage harvester without processor set 6-mm (PT6) self-propelled (SP6), 12-mm (SP12), 18-mm (SP18). Proces...

Three Angus steers (410 kg) cannulated in the proximal duodenum were used in a replicated 3 x 3 Latin square to evaluate the effects of dietary lipid level and oil source on ruminal biohydrogenation and conjugated linoleic acid (CLA) outflow. Dietary treatments included: 1) typical corn (TC; 79.2% typical corn), 2) high-oil corn (HOC; 79.2% high-oil corn), and 3) the TC diet with corn oil added...

The purpose of this study was to evaluate the effects of increasing levels of saponins from Quillaja saponaria on fatty acid (FA) composition and cholesterol content in muscle Longissimus dorsi of lambs. A total of 24 Barbarine lambs were assigned to four dietary treatments: control diet (C) consisting of oat hay ad libitum and 400 g of concentrate (80% barley, 17.5% soybean meal and 2.5% vitam...

Conjugated linoleic acid is a mixture of positional and geometric isomers of linoleic acid with two conjugated unsaturated double bonds at various carbon positions in the fatty acid chain. An increasing interest on CLA is attributed to its potential health benefits such as anticarcinogenic, antiatherogenic, antidiabetic and antiadipogenic effects. More than a dozen isomers of CLA are present in...
