Sodium Salicylate During The First 7 Days Of Lactation Affects The Entire Lactation (2012), Jaymelynn K. Farney, Laman Mamedova, J. Ernest Minton, J. F. Coetzee

Kansas Agricultural Experiment Station Research Reports

Inflammation has been proposed as a contributor to metabolic disorders in transition dairy cows. The purpose of this experiment was to determine if a non-steroidal anti-inflammatory drug, sodium salicylate (SS), benefits transition cows. At calving, 78 cows [primiparous (1P) n = 39; 2nd lactation (2P) n = 24; ≥3 lactations (3P) n = 15] were assigned alternately to either a control or SS treatment for 7 days and production responses were evaluated through the entire lactation. Treatment was administered via individual water bowls, delivering a mean of 123 ± 5.5 (mean ± standard deviation) grams salicylate per day during the …


Meta-Analysis Of The Effects Of Dietary Sugar On Intake And Productivity Of Dairy Cattle (2012), C. F. Vargas, Christopher D. Reinhardt, J. L. Firkins, Barry J. Bradford Jan 2012

Meta-Analysis Of The Effects Of Dietary Sugar On Intake And Productivity Of Dairy Cattle (2012), C. F. Vargas, Christopher D. Reinhardt, J. L. Firkins, Barry J. Bradford

Kansas Agricultural Experiment Station Research Reports

A meta-analysis was performed to determine the possible effects of dietary sugar on feed intake and milk production in lactating dairy cattle. The database used in this analysis included 18 treatment comparisons frozm 10 studies reported from 1985 through 2011. Treatment comparisons were used only if: (1) either sucrose (9 comparisons) or molasses (9 comparisons) replaced corn grain without adding fat; and (2) sugar added by treatment ranged from 2 to 5% of dry matter. First, responses to sucrose and molasses were compared to assess whether these sugar sources could be considered together. Statistical analysis provided no evidence for different …


Hot Topic: New Research Highlights The Need For Holistic Thinking About Transition Cows (2012), Barry J. Bradford Jan 2012

Hot Topic: New Research Highlights The Need For Holistic Thinking About Transition Cows (2012), Barry J. Bradford

Kansas Agricultural Experiment Station Research Reports

In the past, efforts to improve the transition to lactation have focused largely on preventing infections and maximizing energy intake in transition cows, and these issues have generally been treated independently. New models, however, are emerging to explain the development of numerous transition disorders. A combination of insults, including social stress, negative energy balance, heat stress, endotoxin exposure, and oxidative stress may promote inflammation, suppress feed intake, and impair both metabolic and immune function during the transition period. These models suggest that transition cow management must be viewed holistically, because the cow's environment, nutrition, and immune function interact in many …


Reinsemination Intervals After Timed Artificial Insemination Or Estrus-Detected Inseminations (2012), Jeffrey S. Stevenson Jan 2012

Reinsemination Intervals After Timed Artificial Insemination Or Estrus-Detected Inseminations (2012), Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

The objective was to quantify the reinsemination intervals of lactating dairy cows that were either inseminated at estrus or received a timed AI (TAI) at first service. Cows in Experiment 1 were enrolled in a TAI program before first AI after calving. Cows detected in estrus after 50 days in milk (DIM) were inseminated, whereas the remainder continued in the TAI program and were inseminated as scheduled. Cows in Experiment 2 also were enrolled in a TAI program and were inseminated accordingly at first service after calving. On day 7 after TAI, cows were assigned randomly to receive either saline …
