Fecal and urinary lignans, intrafollicular estradiol, and endometrial receptors in lactating dairy cows fed diets supplemented with hydrogenated animal fat, flax or sunflower seed
Download2008
Colazo, M. G., Okine, E. K. , Ambrose, D. J., Dyck, M. K., Oba, M., Thangavelu, G.
We hypothesized that the inclusion of flaxseed in the diets of lactating dairy cows will increase urinary and fecal concentrations of the lignans, secoisolariciresinol diglycoside (SDG), enterolactone and enterodiol, reduce intrafollicular concentrations of IGF-I and estradiol, and subsequently...

Residual feed intake adjusted for backfat thickness and feeding frequency is independent of fertility in beef heifers
Download2011
McCartney, D., Ambrose, D. J., Colazo, M. G., Baron, V. S., Novak, S., Basarab, J. A.
This study examined the effects of residual feed intake (RFI), RFI adjusted for off-test backfat thickness (RFIfat) and RFI adjusted for off-test backfat thickness and feeding event frequency (RFIfat & activity) on heifer fertility and productivity. Beef heifers (n=190) were monitored for...
