Effect of increasing degradable intake protein on intake and digestion of low-quality, tallgrass-prairie forage by beef cows.
TLDR
Monitoring intake, ruminal fermentation responses, and site and extent of digestion associated with providing increasing amounts of supplemental degradable intake protein (DIP) generally improved forage utilization.
Standardization of in situ techniques for ruminant feedstuff evaluation.
TLDR
The lack of standardization in rinsing techniques and the failure or inability to correct for microbial contamination of in situ residues seem to be the major sources of variability with in situ procedures.
Influence of dietary energy on follicular development, serum gonadotropins, and first postpartum ovulation in suckled beef cows.
TLDR
Pre- and postpartum level of dietary energy influenced birth weight and weight gain of calves, milk production, concentrations and pulse frequency of LH in serum, appearance rate of large follicles, and the interval to first ovulation.
Effects of different supplemental sugars and starch fed in combination with degradable intake protein on low-quality forage use by beef steers.
TLDR
In conclusion, even though some consistency in fermentation profiles for different carbohydrate sources was evident in both experiments, forage intake and digestion responses were not consistent across experiments, which raises the possibility that carbohydrate source may interact with the amount of supplemental DIP fed.
Vegetation trends in tallgrass prairie from bison and cattle grazing
TLDR
This 10-year study compared vegetation changes in Kansas tallgrass prairie that was burned and grazed season-long at a moderate stocking rate by either bison or cattle to find that little bluestem (Schizachyrium scoparium) cover decreased over time in bison pastures, and big bluestems (Andropogon gerardii) cover increased over timeIn cattle pastures.
Effect of frequency of supplementation and protein concentration in supplements on performance and digestion characteristics of beef cattle consuming low-quality forages.
TLDR
Daily supplementation maximized forage intake and cow performance, although the magnitude of performance differences was not large, and response to supplementation frequency was not dependent on supplement CP concentration or grain type.
Grazing management effects on plant species diversity in tallgrass prairie
TLDR
It is suggested that large grazer densities, fire, and annual climatic variability interact to influence patterns of plant community composition and diversity in tallgrass prairie.
Influence of timing of gain on growth and reproductive performance of beef replacement heifers.
TLDR
Data indicate that delaying the majority of weight gain until late in heifer development may decrease costs without detrimental effects on reproductive performance, and body weight at the onset of the breeding season and weight at puberty were not different between treatments in either year.
Effects of calcium soaps of fatty acids on postpartum reproductive function in beef cows.
Twelve multiparous Simmental cows (584 kg) were used to determine the influence of calcium soaps of fatty acids (CSFA) incorporated in a range supplement on postpartum reproductive characteristics.
