Perfil de ácidos graxos do leite de vacas alimentadas com óleo de soja e monensina no início da lactação Milk fatty acid profile of cows fed monensin and soybean oil in early lactation

Revista Brasileira de Zootecnia, 2006
Avaliaram-se os efeitos da adição de monensina sódica combinada com óleo de soja na dieta de vacas lactantes sobre o perfil de ácidos graxos (AG) do leite na 5ª e 15ª semanas da lactação.

The protection of the unsaturated fatty acids of dried grass and sunflower seed against biohydrogenation by rumen micro-organisms : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Animal Science at Massey University [PDF]

, 1974
Ryegrass which had been dried and treated with HCHO was incubated with the rumen contents of a pasture-grazed cow. The protein in the grass was protected from degradation by the rumen microbes.

In situ ruminal biohydrogenation of fatty acids from extruded soybeans: effects of dietary adaptation and of mixing with lecithin or wheat straw [PDF]

, 2004
Kinetics and intermediates of biohydrogenation of fatty acids were investigated in situ using extruded soybeans, a blend of extruded soybeans and lecithin (99:1), or a blend of extruded soybeans plus wheat straw (66:34).

Efficacy of Supplementing Lemongrass Powder on Growth, Metabolism, Immune and Endo‐Parasitic Status of Lambs in the Tropics

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
Dietary supplementation of lemongrass powder (0.50 g per kg metabolic body weight) with a basal diet significantly enhanced lamb daily gain, growth velocity, feed efficiency and nutrient digestibility. It increased serum high‐density lipoprotein cholesterol (HDL‐C), albumin and IgG concentrations, while reducing aspartate aminotransferase (AST ...

Selenite and selenate affect the fatty acid profile in in vitro incubated ovine ruminal fluid containing linseed oil

Czech Journal of Animal Science, 2013
The influence of selenite (SeIV) or selenate (SeVI) added to ovine ruminal fluid containing linseed oil (LO) on the profile of fatty acids (FA), particularly conjugated linoleic acid (CLA) isomers, was investigated.

Sainfoin (Onobrychis viciifolia) silage in dairy cow rations reduces ruminal biohydrogenation and increases transfer efficiencies of unsaturated fatty acids from feed to milk

Animal Nutrition, 2020
The effects of replacing grass silage by sainfoin silage in a total mixed ration (TMR) based diet on fatty acid (FA) reticular inflow and milk FA profile of dairy cows was investigated. The experiment followed a crossover design with 2 dietary treatments.

Effects of including white clover and plantain species in perennial ryegrass pastures on qualitative indicators and metabolome of milk

International Journal of Dairy Technology, Volume 79, Issue 1, January–March 2026.
Mixed sward pasture systems are being investigated due to their potential to improve bio diversity and sustainability metrics; our study provides a due diligence on the impact of pastures containing perennial ryegrass, white clover and plantain species on the composition and functionality of milk.

Enzymatic approach of linoleic acid ruminal biohydrogenation [PDF]

, 2009
Ruminal biohydrogenation (BH) corresponds to a microbial reduction of dietary unsaturated fatty acid. The linoleic acid (C18:2) BH is divided into three steps: first an isomerisation into conjugated linoleic acids (CLA), then a reduction producing mainly

Association of Metabolic Disease Occurrence on Milk Fatty Acid Composition and Rumination Time in Early Lactation Dairy Cows and Evaluation of Their Potential as Diagnostic Indicators

Animal Science Journal, Volume 97, Issue 1, January/December 2026.
ABSTRACT This study investigated the relationship between metabolic disease, milk fatty acid composition, and rumination time in early lactation dairy cows and evaluated their utility as diagnostic indicators. Twenty‐two Holstein dairy cows were monitored for 8 weeks postpartum, with weekly milk and blood sampling and continuous rumination monitoring ...

Camelina Seed Supplementation at Two Dietary Fat Levels Change Ruminal Bacterial Community Composition in a Dual-Flow Continuous Culture System

Frontiers in Microbiology, 2017
This experiment aimed to determine the effects of camelina seed (CS) supplementation at different dietary fat levels on ruminal bacterial community composition and how it relates to changes in ruminal fermentation in a dual-flow continuous culture system.
