Influence Of Facilities On Cow Time Budgets (2006), Joseph P. Harner, John F. Smith, Michael J. Brouk Jan 2006

Influence Of Facilities On Cow Time Budgets (2006), Joseph P. Harner, John F. Smith, Michael J. Brouk

Kansas Agricultural Experiment Station Research Reports

A model was developed to evaluate the impact of facilities on cow time budgets. The model suggests that in inadequate facilities overcrowding of the facility by 25% or more resulted because occupancy rate exceeded 100%. The model also is useful in evaluating the impact of time at milking center and milk-ing frequency on cow time budget. In general, the first groups of cows through the milking parlor will have adequate time for resting, feeding, socializing, and watering. The last groups of cows through the parlor, however, do not have adequate time for these activities if the time at the milking …

Ovulation Potential Of Human Chorionic Gonadotropin Versus Gnrh (2006), B.S. Buttrey, M.G. Burns, Jeffrey S. Stevenson Jan 2006

Ovulation Potential Of Human Chorionic Gonadotropin Versus Gnrh (2006), B.S. Buttrey, M.G. Burns, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Experiments have shown human chorionic gonadotropin (hCG) to be more effective than GnRH as a means to induce ovulation of folli-cles. Dosages used, however, have differed greatly among experiments. A study was per-formed to determine the minimum effective dose of hCG needed to induce ovulation of ovarian follicles in dairy cows. Ovaries of Holstein cows were mapped by using transrec-tal ultrasonography 7 days before a bi-weekly pregnancy diagnosis. Cows were assigned randomly to treatments of saline, 100 μg of GnRH (2 mL of Fertagyl, Intervet, Inc., Mills-boro, NJ), or 500, 1000, 2000, or 3000 IU of hCG (0.5, 1, 2, …

Comparison Of Dectomax And Valbazen On Beef Cattle Carcass Traits (2006), J.A. Christopher, T.T. Marston, J.R. Brethour, Gerald L. Stokka Jan 2006

Comparison Of Dectomax And Valbazen On Beef Cattle Carcass Traits (2006), J.A. Christopher, T.T. Marston, J.R. Brethour, Gerald L. Stokka

Kansas Agricultural Experiment Station Research Reports

The objective of this trial was to determine if types of dewormers affected carcass characteristics. Crossbred steers (n=428) were stratified by weight and ultrasound marbling score and administered either Dectomax (subcutaneous injection) or Valbazen (oral) dewormer. Fecal egg counts indicated that both dewormers cleared internal parasites from the cattle. Carcass data indicated that Dectomax increased fat deposition as measured by 12th rib back fat; kidney, pelvic, and heart fat; and marbling score, when compared with Valbazen. Deworming products may affect carcass traits that are used to value cattle.

Since their discovery in 2000, pig umbilical cord stem cells have been studied at KState. The studies have been expanded to included other species, including humans. In addition, other research groups around the world have published scientific studies with these cells. Their unique attributes include being plentiful, easily collected, and (in humans) non-controversial. Initial work in the pig has concentrated on characterizing the cells to understand how they compare with other populations of stem cells. Results indicate that they have several characteristics in common with other primitive stem-cell populations, and that they are relatively easy to work with in the …

Kansas Agricultural Experiment Station Research Reports

A total of 482 pigs (initial BW of 21.9 lb) were used in a 22-d study to determine the effects of dried distillers grains with solubles (DDGS) on growth performance of nursery pigs reared in a commercial environment. Pigs were allotted to one of two dietary treatments based on corn-soybean meal and containing either 0 or 10% DDGS. There was a tendency for pigs fed the diet containing 10% DDGS to have decreased (P<0.13) ADG, compared with pigs not fed DDGS (0.95 vs. 0.88 lb/d). Overall (d 0 to 22), there were no differences in ADFI, F/G, or final weight (P>0.21). For economic analysis, the DDGS price was compared at $109, $93, or $80/ton. There were no differences in feed cost per pound of gain in …
