Abstract The potential to modify the milk fatty acid (FA) composition by changing cow or goat diets is reviewed. Ruminal biohydrogenation (RBH), combined with mammary lipogenic and Δ‐9 desaturation pathways, considerably modifies profile of dietary FA thus composition. pasture has major effects decreasing saturated increasing considered as favorable for human health ( c 9‐18:1, 18:3 n ‐3 9 t 11‐CLA), compared winter diets, especially those based on maize silage concentrates. Plant lipid...
After a brief survey of metabolic pathways and nutrient fluxes involved in mammary lipogenesis, this review summarises the known effects diet on ruminant milk fat composition.Special attention is given to fatty acids that could play positive role for human health, such as butyric acid, oleic C18 C22 polyunsaturated conjugated linoleic acid (CLA).The efficiency transfer C18:2, C18:3, C20:5, C22:5 C22:6, from duodenum milk, reviewed.The main dietary factors taken into account are nature...
An ovine-specific RIA, shown to be reliable for bovine leptin determination, was used study the effects of breed, body fatness, feeding level, and meal intake on plasma level in adult cattle. Eighteen fat Charolais, Holstein, lean Holstein cows were either well-fed (130% maintenance energy requirements [MER]) or underfed (60% MER) 3 wk. The breed tended have a small effect which decreased by 70% (P < 0.05) compared cows. A strong curvilinear relationship found between mean adipocyte volume...
Abstract The objectives of this study were to explore bacterial community assembly from cow teat skin raw milk cheeses and evaluate the role farming systems on using 16S rRNA gene high-throughput sequencing. two grazing studied (extensive vs. semi-extensive) had a greater effect microbiota than that milks cheeses. On skin, relative abundance several taxa at different taxonomic levels ( Coriobacteriia , Bifidobacteriales Corynebacteriales Lachnospiraceae Atopobium Clostridium) varied...
Abstract It is well established that plant oils reduce milk saturated fatty acid content and enhance concentrations of conjugated linoleic (CLA) trans C 18:1 in fat, but there increasing evidence to suggest fat CLA responses are often transient decline over time. probable time dependent adaptations ruminal biohydrogenation changes composition lipid supplements are, at least part, related the basal diet. To test this hypothesis, 18 Holstein cows were used a continuous randomized block design...
Based on the potential benefits to long-term human health there is interest in developing sustainable nutritional strategies for reducing saturated and increasing specific unsaturated fatty acids ruminant milk. The impact of plant oil supplements diets containing different forages caprine milk acid composition was examined two experiments using twenty-seven Alpine goats replicated 3 × Latin squares with 28 d experimental periods. Treatments comprised no (control) or 130 g/d sunflower-seed...
Dairy fat contains high amounts of saturated fatty acids (FA), which are associated with cardiovascular disease (CVD) risk. Manipulation dairy cows nutrition allows to decrease the FA content milk fat, and is increases either in conjugated linoleic acid (CLA) trans-11-C18:1 contents, or trans-10-C18:1 content. CLA putatively exhibits beneficial properties on CVD risk, whereas trans suspected be detrimental. The present study compared effects a trans-10-C18:1-rich butter (T10 butter),...
