Milk Production, Milk Fatty Acid Profiles and Blood Metabolites in Holstein Dairy Cows Fed Diets Based on Dried Citrus Pulp
The objective of the present study was to determine the effect of substitution of corn grain with dried citrus pulp (DCP) on milk composition, fatty acids profiles and blood metabolites in Holstein dairy cows. These parameters were measured in a replicated 4 × 4 latin square design experiment using eight Holstein cows. Each experimental period lasted 4 weeks. The four treatments were: control (...

متن کاملDigestion, milk production, milk composition, and blood composition of dairy cows fed formaldehyde treated flaxseed or sunflower seed.
Forty midlactation Holstein cows averaging 635 kg of body weight (SE = 8) were allotted at wk 25 of lactation to ten groups of four cows blocked for similar calving dates to determine the effects of formaldehyde treatment of flaxseed and sunflower seed on fatty acid composition of blood and milk, milk yield, feed intake, and apparent digestibility. Cows were fed a total mixed diet based on gras...
متن کاملEffect of Dietary and Animal Factors on Milk Fatty Acids Composition of Grazing Dairy Cows: A Review
In pasture-based milk production systems, using available farm resources in order to reduce feeding costs, the composition and functional properties of dairy cows’ milk are of considerable importance to the dairy farmer, manufacturer and consumer. Basically, there are three options for altering the composition and/or functional properties of milk: 1) cow nutrition and grazing management, 2) cow...
متن کاملEffects of peripartum biotin supplementation of dairy cows on milk production and milk composition with emphasis on fatty acids profile
Forty Holstein dairy cows receiving a 38% concentrate diet based on maize silage were assigned to either a control group, either a biotin group, receiving 20 mg of biotin per day from 15 days before expected calving date and for 120 days after calving. Milk production was measured daily, milk fat content, protein content, urea and somatic cell counts were determined weekly from week 2 to week 1...
