Various estrus-synchronization programs for heifers

Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 2011-07-22)

Various programs of estrus synchronization have been tested during the last 6 years to determine the least costly and most efficacious for dairy heifer replacements. Four systems were tested: 1) a modified Ovsynch treatment ...
Use of video image analysis, ribeye grids, and linear ribeye measurements to predict and compare ribeye areas from carcass left and right sides

Waylan, A.T.; Campbell, R.E.; Unruh, John A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-09-02)

Ribeye tracings from 265 beef carcasses were used to compare ribeye areas from right and left sides. When video image analysis (VIA) was used to determine ribeye area, no difference (P=.48) was observed between right and ...
Ultrasound versus convection cooking of beef longissimus and pectoralis muscles

Pohlman, F.W.; Zayas, J.F.; Dikeman, Michael E.; Unruh, John A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-09-02)

Longissimus and pectoralis muscles were removed from 10 steer carcasses at 4 days postmortem , aged for 14 days at 4 ̊F, then assigned to either ultrasound (ULS) or convection (Conv) cooking to either 144 or 15 8 ...
Trends in the swine industry: productivity measures

Dhuyvetter, Kevin C.; Parcell, J.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-03-02)

Productivity has been trending up in the swine industry over the last 15 years. Much of the increased productivity is due to increased pigs/litter and increased market weights. The efficiency of the breeding herd (lit ...
Trends in the swine industry: operations and marketings

Parcell, J.L.; Dhuyvetter, Kevin C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-03-02)

Trends in the size of swine operations in Kansas and the V. S. are toward fewer and larger operations. The number of operations in Kansas and the U.S. continues to decline; however, the number of hogs marketed has ...

Synchronization of estrus and ovulation in dairy heifers using norgestomet, GnRH, and PGF[subscript]2alpha

Stevenson, Jeffrey S.; Thompson, K. E.; Smith, John F., 1962-; Hawkins, D. E. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 2011-07-22)

Two experiments were performed using the same treatments. All heifers received two injections of PGF[subscript]2alpha 14 days apart. Controls then were inseminated after detected estrus. Heifers assigned to the two ...
A survey of purchasers of wheat middlings: storage, feeding practices, and problems

Warmann, G.W.; Behnke, Keith C.; Blasi, Dale A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-09-02)

We surveyed 290 purchasers of wheat middlings (WM) from a single flour mill located in central Kansas to characterize the incidence of transport and storage problems and to determine intended animal us e and method of ...
Summary of Kansas State University swine enterprise record

Langemeier, Michael R.; Goodband, Robert D.; Tokach, Michael D.; Nelssen, Jim L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-03-02)

The Kansas Swine Enterprise Record Program evaluates biological and economic performance and is part of a cooperative record- keeping project with Extension personnel and swine producers in Kansas. Nebraska, and South ...
Summary of grazing research on Kansas CRP land

Langemeier, Michael R.; Ohlenbusch, P.D.; Jones, R.D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-09-02)

Animal performance and n et return per acre were examined for four CRP research sites in Kansas in 1 994, 1995, and 1996. Both mowing and prescribed burning increased animal performance in 1994. Mowing was economical ...
Studies on the Growth Conditions for Paecilomyces griseoviride Strain U-2 and Its Ability to Infect Aphids

Steam pasteurization to reduce bacterial populations on commercially slaughtered beef carcasses

Schafer, D.E.; Kastner, Curtis L.; Phebus, Randall K.; Nutsch, Abbey L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-09-02)

A steam pasteurization system (SPS) has been shown in laboratory and commercial evaluations to effectively reduce bacterial populations on freshly slaughtered beef. Our study evaluate d the bactericidal uniformity of ...
Rosvooruzhenie and Russia's return to the world arms market

Stone, David R. (Institute on East Central Europe, Columbia University, 2012-12-20)
Reproductive performance of replacement heifers implanted as young calves or at weaning

Corah, L.R.; Spell, A.R.; Cook, D.L.; Butine, M.D.; Anderson, K.; Grieger, David M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-09-02)

This study evaluated the effect of implanting potential replacement heifers (n=548) with Component E-C® (10 mg of estradiol and 100 mg of progesterone) between 45 and 120 days of age or at weaning (200 days of age) ...
Rapid nutrient evaluation of sorghum silages using two types of near-infrared reflectance spectroscopy
