Digestion, 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 کاملMilk production, milk fatty acid composition, and blood biochemical parameters of Holstein dairy cows fed whole or ground flaxseed instead of extruded soybeans in the first half of lactation
To evaluate the effects of physically processed flaxseed [ground flaxseed (GFS) and whole flaxseed(WFS)] as a replacement for extruded soybeans on feed intake, milk production, milk composition, milk fatty acid (FA) composition and blood biochemical parameters, nine primiparus Holstein dairy lactating cowsaveraging 495 ± 34.5 kg of body weight (BW) and 70 ± 5 days in milk (DIM) were assigned in...
متن کاملEffect of different levels of monensin in diets containing whole cottonseed on milk production and composition of lactating dairy cows
The objective of this study was to determine the effects of feeding different levels of monensin on feed intake, milk production and composition, and milk fattyacid profile in lactating Holstein cows. Four multiparous cows averaging 517 ± 47 (SD) kg in body weight and 101 ± 19.8 (SD) days in milk were housed individually in tie-stalls. The study was conducted as a 4 × 4 Latin square design for ...
متن کاملMilk production and composition, ovarian function, and prostaglandin secretion of dairy cows fed omega-3 fats.
Four multiparous Holstein cows were used in a 4 x 4 Latin square experiment to study the effects of fat sources rich in omega-3 fatty acids on milk production and composition, follicular development, and prostaglandin secretion. All cows were fed a total mixed diet containing 60% grass silage and 40% concentrate. The four treatments were concentrates based either on Megalac, formaldehyde-treate...
