Influence of lipid supplementation on milk components and fatty acid profile

Revista Brasileira de Zootecnia
The objective of this study was to evaluate the effects of different lipid sources in diets for lactating cows on milk yield and composition, conjugated linoleic acid (CLA) content, and fatty acid profile in the milk fat.

Novel genetic engineering technology which increases leaf lipid content modifies the ensiling properties of perennial ryegrass : a thesis presented in partial fulfillment of the requirements for the degree of Masters in Agricultural Science at Massey University, Palmerston North [PDF]

, 2016
A novel strategy to increase the metabolisable energy (ME) yield of pastures has been the development of a genetic engineering technology which increases the leaf lipid content and biomass production of perennial ryegrass (PRG).

The effect of supplementary grass silage and standard concentrate on milk fat fatty acid composition and iodine value when cows are fed a whole rapeseed-based concentrate at pasture [PDF]

, 2010
peer-reviewedThe use of grass silage and concentrates to supplement fresh grass intake is commonly practised in dairy systems. However, the effects of such supplementation within a dietary regime designed to produce a spreadable butter are unknown ...

Potentials to differentiate milk composition by different feeding strategies [PDF]

, 2009
To investigate the effect of the dietary intake of the cow on milk composition, bulk-tank milk was collected on 5 occasions from conventional (n = 15) and organic (n = 10) farms in Denmark and on 4 occasions from low-input nonorganic farms in the United ...

Rates and efficiencies of reactions of ruminal biohydrogenation of linoleic acid according to pH and polyunsaturated fatty acids concentrations [PDF]

, 2006
Data from a previous study about the effects of pH and of linolenic acid (C18:3n-3) andlinoleic acid (C18:2n-6) concentrations on C18:2n-6 biohydrogenation in ruminal cultures were used to calculate the rates and efficiencies of the three reactions of ...

Controlling Rumen Biohydrogenation: Innovation Opportunities in Ruminant Feeding [PDF]

BIO Web of Conferences
Rumen biohydrogenation converts dietary unsaturated fatty acids (UFA) into saturated fatty acids (SFA), reducing the nutritional value of ruminant‐derived meat and milk.

Effects of live yeast on the fatty acid biohydrogenation by ruminal bacteria [PDF]

, 2006
Addition of live yeasts in high concentrate diets for ruminants has been shown to help maintaining the ruminal pH above 6, which could enhance the microbial biohydrogenation of unsaturated dietary fatty acids.

Effects of oil and natural or synthetic vitamin E on ruminal and milk fatty acid profiles in cows receiving a high-starch diet [PDF]

, 2012
Among trans fatty acids, trans-10,cis-12 CLA has negative effects on cow milk fat production and can affect human health. In high-yielding dairy cows, a shift from the trans-11 to the trans-10 pathway of biohydrogenation (BH) can occur in the rumen of ...
