Effect Of Supplemental Carbohydrate Source On The Utilization Of Low-Quality Tallgrass-Prairie Hay By Beef Steers (1998), J.S. Heldt, R.C. Cochran, C.G. Farmer, C.P. Mathis, Evan C. Titgemeyer, Tiruvoor G. Nagaraja
Effect Of Supplemental Carbohydrate Source On The Utilization Of Low-Quality Tallgrass-Prairie Hay By Beef Steers (1998), J.S. Heldt, R.C. Cochran, C.G. Farmer, C.P. Mathis, Evan C. Titgemeyer, Tiruvoor G. Nagaraja
Kansas Agricultural Experiment Station Research Reports
Twenty ruminally fistulated steers were used in different two experiments to evaluate the effects of supplemental carbohydrate source (starch, glucose, fructose, or sucrose) fed at .3% BW/day on the utilization of low-quality tallgrass-prairie hay. In Experiment 1, all supplemental carbohydrates were fed with a low level of supplemental degradable intake protein. In Experiment 2, the level of supplemental degradable intake protein was high. Intake of the tallgrass-prairie hay was not affected significantly by supplementation in either experiment, but as a result of the added carbohydrate, total intake was increased. When supplemental protein intake was inadequate, supplemental carbohydrates depressed digestion, but …

Site Of Semen Deposition And Fertility In Lactating Beef Cows Synchronized With Gnrh And Pgf2Α (1998), G.C. Lamb, K. E. Thompson, K. Anderson, David M. Grieger, Timothy G. Rozell, Jeffrey S. Stevenson
Kansas Agricultural Experiment Station Research Reports
Our objective was to determine the effect of site of semen deposition on pregnancy rate in beef cows inseminated at a fixed time or after observed estrus. Cows were synchronized with a combination of gonadotropin-releasing hormone (GnRH) prostaglandin-F α (PGF). GnRH was injected 7 days before PGF (day 0; first of breeding season). The trial was conducted at two locations, one in Kansas (147 cows) and one in Colorado (313 cows). At each location, cows were assigned to be inseminated after observed estrus (ESTRUS-AI) or at a fixed time (TIMED-AI). Within these two groups, cows either were inseminated in the …
Effects Of Supplemental Degradable Intake Protein On Intake And Digestibility Of Bermuda Hay (1998), C.P. Mathis, R.C. Cochran, J.S. Heldt, B.C. Woods, Gerald L. Stokka, K. C. Olson, Evan C. Titgemeyer
Effects Of Supplemental Degradable Intake Protein On Intake And Digestibility Of Bermuda Hay (1998), C.P. Mathis, R.C. Cochran, J.S. Heldt, B.C. Woods, Gerald L. Stokka, K. C. Olson, Evan C. Titgemeyer
Kansas Agricultural Experiment Station Research Reports
A study with 16 ruminally fistulated beef steers fed Bermuda hay ad libitum showed that the intake and digestibility of hay was not influenced by increasing levels of supplemental degradable intake protein (DIP). However, the hay used in this study was of medium quality; lower quality Bermuda hay with lower CP may respond to supplemental DIP.
Effects Of Increasing Amounts Of Supplemental Soybean Meal On Intake And Digestibility Of Tallgrass-Prairie Hay (1998), C.P. Mathis, R.C. Cochran, J.S. Heldt, B.C. Woods, Gerald L. Stokka, K. C. Olson
Effects Of Increasing Amounts Of Supplemental Soybean Meal On Intake And Digestibility Of Tallgrass-Prairie Hay (1998), C.P. Mathis, R.C. Cochran, J.S. Heldt, B.C. Woods, Gerald L. Stokka, K. C. Olson
Kansas Agricultural Experiment Station Research Reports
Twenty ruminally fistulated beef steers free-choice access to prairie hay were used to evaluate the effect of increasing level of soybean meal (SBM) on forage intake and digestion. Forage intake, total organic matter intake, and organic matter digestion were enhanced with increasing level of SBM supplementation, although forage intake and digestion appeared to plateau at higher levels. The concomitant rises in intake and digestion as supplemental SBM increased resulted in an increase in total digestible organic matter intake, with the largest response to the initial increment of supplement.
Milking Two Or Five Times Daily In The Presence Of A Cow’S Own Nonsuckling Calf Fails To Prolong Postpartum Anovulation (1998), G.C. Lamb, K. E. Thompson, J.S. Heldt, C.A. Löest, Jeffrey S. Stevenson
Milking Two Or Five Times Daily In The Presence Of A Cow’S Own Nonsuckling Calf Fails To Prolong Postpartum Anovulation (1998), G.C. Lamb, K. E. Thompson, J.S. Heldt, C.A. Löest, Jeffrey S. Stevenson
Kansas Agricultural Experiment Station Research Reports
Three treatments were initiated at approximately 15 days after calving and continued for 4 weeks: 1) cows were suckled ad libitum by their calves (calf present [CP]); 2) calves were present but nonsuckling 24 hr/day and cows were milked twice daily (CR+2xM); 3) or same as CR+2xM but cows were milked five times daily (CR+5xM). Interval to the first postpartum ovulation was similar between CR+2xM and CR+5xM cows but about 2 weeks less than that in cows suckled ad libitum by their own calves. Cows in the CR+5xM treatment produced more milk than cows in the CR+2xM treatment, whereas only …
Effects Of Base Ingredient In Cooked Molasses Blocks On Intake And Digestion Of Prairie Hay By Beef Steers (1998), R.H. Greenwood, Evan C. Titgemeyer, James S. Drouillard
Effects Of Base Ingredient In Cooked Molasses Blocks On Intake And Digestion Of Prairie Hay By Beef Steers (1998), R.H. Greenwood, Evan C. Titgemeyer, James S. Drouillard
Kansas Agricultural Experiment Station Research Reports
Blocks based on cooked beet molasses, cane molasses, or concentrated separator by-product, CSB) were tested to compare their effects on intake and digestion of prairie hay by beef steers. All blocks contained at least 30% crude protein. Steers fed the cooked molasses blocks consumed and 22% more forage than control steers, but forage intakes were not different among the three different blocks. Intakes of digestible organic matter and neutral detergent fiber, indicators of energy available to the steers, were increased 38 and 29% respectively, by block supple-mentation but were not different among the three blocks. However, total tract organic matter …
Supernumerary Teeth In Pleistocene, Recent, And Hybrid Individuals Of The Spermophilus Richardsonii Complex (Sciuridae), H. Thomas Goodwin
Supernumerary Teeth In Pleistocene, Recent, And Hybrid Individuals Of The Spermophilus Richardsonii Complex (Sciuridae), H. Thomas Goodwin
Faculty Publications
A supernumerary distal upper molar, always expressed bilaterally, occurred in Pleistocene (one of 204) and Recent (five of 1,667) specimens of the Spermophilus richardsonii complex. Among Recent specimens with the abnormality, three of four with known provenance came from adjacent colonies with hybrids of S. richardsonii (Richardson's ground squirrel) and S. elegans (Wyoming ground squirrel). Elsewhere, the trait was rare in S. richardsonii (one of 947) and absent in S. elegans (out of 668). Affected individuals exhibited normal P3-M2, but two aberrant teeth distal to M2. Aberrant teeth exhibited a mosaic of features typical of M2, M3, and atypical of …
Ecology Of The Eastern Cottonmouth (Agkistrodon P. Piscivorus) At Back Bay National Wildlife Refuge: A Comparative Study Of Natural And Anthropogenic Marsh Habitats, Chad Lee Cross
Biological Sciences Theses & Dissertations
Mark-recapture sampling and radiotelemetry were used to investigate populations of the eastern cottonmouth, Agkistrodon p. piscivorus, in both natural and anthropogenic marsh habitats at Back Bay National Wildlife Refuge (BBNWR), Virginia Beach, Virginia from autumn 1995 to late spring 1998. Mark-recapture subjects were captured, marked by ventral scale-clipping, and released back into the population. A modified Schnabel Census estimator was used to estimate population sizes and corresponding densities in both marsh systems based on a total of 244 captures of 222 individuals. Most snakes were found >0.05 in from water, but it was apparent that proximity to water played …

The effects of supplementation with mixed fodder or concentrate were investigated on the performance of a) growth of male lambs;md kids grazing extensively under oil palm trees and b) reproduction of ewes and goats stall-fed with native herbage. Supplemented kids and lambs had higher average daily weight gain than controls but the effect was only significant for those which received concentrate (p < 0.05). Final body weight was only significantly different from controls for lambs supplemented with concentrate (p < 0.05). The ages at puberty, first mating, first conception and first kidding of supplemented goats were about 110 days earlier than those for controls (p < 0.05 or better). Supplemented goats had first mating and conceived at lower body weights (p < 0.01) than those in control groups. Different feeding regimes had no effects (p > 0.05) on the reproductive performance of ewes apart fi om highest body weight of first lambing in animals supplemented with concentrate (p < 0.05). Native herbage available under oil palm trees of 5 years old was sufficient for growth …
