Effects of polyunsaturated fatty acids from plant oils and algae on milk fat yield and composition are associated with mammary lipogenic and SREBF1 gene expression.
TLDR
Examination of long-term supplementing diets with saturated or unprotected polyunsaturated fatty acids from two different plant oils rich in either n-3 or n-6 fatty acids plus docosahexaenoic acid (DHA)-rich algae on mammary gene expression and milk fat composition in lactating dairy cows found a positive relationship between mammary SCD1 and SREBF1 mRNA abundances was observed, suggesting a similar regulation for these genes.

Effects of diet and storage on fatty acid profile, micronutrients and quality of muscle from German Simmental bulls.
TLDR
The treatment diet was not effective to give similar daily live weight gain to the control diet, but it was successful in improving beef fatty acid composition without affecting tenderness and colour (under unrestricted conditions). Expand
Calf’s sex, parity and the hour of harvest after calving affect colostrum quality of dairy cows grazing under high tropical conditions
TLDR
The calf’s sex was shown to have an effect on the amount of colostrum, on the concentration of fat, and on theamount of milk produced by lactating Holstein cows; all were higher in cows that gave birth to a female calf. Expand
Nutritional evaluation of fruit and vegetable waste as feedstuff for diets of lactating Holstein cows.
TLDR
Results showed that FV can be used as a dietary ingredient for high-yield lactating cows without detriment in the milk yield and with improvement in the Milk quality, the main impact of these results is the alternative generated for the improvement of the environment. Expand
Quantitative and nutritional characterization of fruit and vegetable waste from marketplace: a potential use as bovine feedstuff?
TLDR
FV represents a potential feedstuff for bovine feeding, and its recycling could avoid the discharge of a large amount of waste to landfills, which would minimize its environmental impact. Expand
Dietary fatty acid intervention of lactating cows simultaneously affects lipid profiles of meat and milk.
TLDR
It was demonstrated that dietary fatty acid manipulation substantially shifted the fatty acid profiles of milk and to a lesser extent of meat, whereas meat quality traits were not affected. Expand
Relationship between lipid peroxidation and antioxidant status in the muscle of German Holstein bulls Fed n-3 and n-6 PUFA-enriched diets.
TLDR
The present results suggest that the antioxidant defense in muscle of the n-3 PUFA-enriched diet group could balance reactive substances under low oxidative conditions, however, the antioxidant capacity was not sufficient under abundant accumulation of reactive substances. Expand
Supplementation with bypass fat in silvopastoral systems diminishes the ratio of milk saturated/unsaturated fatty acids
TLDR
There was a significant decrease in the amount of saturated fatty acid in both experiments while the unsaturated fat increased significantly in experiment 1 and remained stable in experiment 2, thus improving the saturated/unsaturated ratio without a negative effect on total milk yield in fat or protein. Expand
Nutrient Management in Silvopastoral Systems for Economically and Environmentally Sustainable Cattle Production: A Case Study from Colombia
In recent years, livestock production has received negative publicity due to environmental degradation. Critics charge that the expansion of cattle production around the world has destroyed theExpand
Antioxidant enzyme activities and antioxidant capacity in longissimus muscle from bulls fed diets rich in polyunsaturated fatty acids.
TLDR
The effect of a treatment diet composed of grass silage and concentrate including rapeseed on the antioxidant enzyme activities of fresh longissimus muscle from German Simmental bulls and the effect of diet on antioxidant capacity (AOC) of hydrophilic and lipophilic antioxidants was evaluated in fresh and stored beef muscle.
