Luteolysis and pregnancy outcomes in dairy cows after treatment with estrumate or lutalyse

Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-11-22)

In Experiment 1, lactating dairy cows (n = 1,230) in 6 herds were treated with 2 injections of prostaglandin F2α (PGF2α) 14 days apart (Presynch), with the second injection administered 12 to 14 days before the onset of a ...
Effects of acidified fermentation by-products and prepartum DCAD on feed intake, performance, and health of transition dairy cows

Bradford, Barry J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-11-22)

Two commercially available acidified fermentation by-products were evaluated in the close-up period (21 days before expected calving) for their effects on feed intake, postpartum performance, and cow health. Diets were ...
Effect of acidulant addition on yogurt fermentation

Schmidt, Karen A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-11-22)

Yogurt was manufactured by pre-acidifying the yogurt mix with citric acid, lactic acid, or concentrated lemon juice either before or after pasteurization to a target pH of 6.2, and then the traditional manufacturing process ...
Influences of heat stress on serological response and performance of dairy calves

Hollis, Larry C.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-11-22)

Objectives of this study were to investigate the possible effects of heat stress on calf growth and the development of active immunity. Eighteen heifer calves born between July 21 and August 24, 2008, were housed in ...
Impact of evaporative pads and cross ventilation on core body temperature and resting time of lactating cows

Smith, John F., 1962-; Bradford, Barry J.; Harner, Joseph P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-11-22)

A trial was conducted to determine the impact of evaporative cooling pads on core body temperature (CBT), time spent lying, and number of lying bouts of Holstein cows housed in cross-ventilated freestall facilities. ...
