Milk fatty acids in dairy cows fed whole crude linseed, extruded linseed, or linseed oil, and their relationship with methane output.
This experiment studied the effect of 3 different physical forms of linseed fatty acids (FA) on cow dairy performance, milk FA secretion and composition, and their relationship with methane output. Eight multiparous, lactating Holstein cows were assigned to 1 of 4 dietary treatments in a replicated 4 x 4 Latin square design: a control diet (C) based on corn silage (59%) and concentrate (35%), a...
متن کاملMethane output and diet digestibility in response to feeding dairy cows crude linseed, extruded linseed, or linseed oil.
This experiment studied the effect of 3 forms of presentation of linseed fatty acids (FA) on methane output using the sulfur hexafluoride tracer technique, total tract digestibility, and performance of dairy cows. Eight multiparous lactating Holstein cows (initial milk yield 23.4 +/- 2.2 kg/d) were assigned to 4 dietary treatments in a replicated 4 x 4 Latin square design: a control diet (C) co...
متن کاملEffects of Linseed Oil or Whole Linseed Supplementation on Performance and Milk Fatty Acid Composition of Lactating Dairy Cows
The objective of this study was to determine the effects of linseed oil or whole linseed supplementation on performance and milk fatty acid composition of lactating dairy cows. Thirty six Holstein Friesian crossbred lactating dairy cows were blocked by milking days first and then stratified random balanced for milk yields and body weight into three groups of 12 cows each. The treatments consist...
متن کاملEffects of forage type and extruded linseed supplementation on methane production and milk fatty acid composition of lactating dairy cows.
Replacing dietary grass silage (GS) with maize silage (MS) and dietary fat supplements may reduce milk concentration of specific saturated fatty acids (SFA) and can reduce methane production by dairy cows. The present study investigated the effect of feeding an extruded linseed supplement on milk fatty acid (FA) composition and methane production of lactating dairy cows, and whether basal forag...
متن کاملTranscript profiling in the milk of dairy ewes fed extruded linseed
The identification of genes regulating milk secretion by mammary glands is a key-step for exploiting changes in milk composition induced by different diet regimens. Linseed supplementation is a reliable feeding strategy to enhance polyunsaturated fatty acid content in milk fat from sheep, increasing milk quality and nutraceutical value. To investigate the molecular bases of diet induced differe...
