Effects Of Frequency Of Protein Supplementation On Performance By Beef Calves Grazing Dormant Native Range, G. W. Preedy, J. R. Jaeger, J. W. Waggoner, K C. Olson

Kansas Agricultural Experiment Station Research Reports

Stocker calves that graze forages before entering a feedlot account for more than 75% of the beef calves raised in the United States each year. A large proportion of those will be calves born in the spring and weaned in the fall. Modest growth rates are expected when the quality of fall and winter forages is poor. Growing calves in confinement systems during fall and winter typically allows for greater average daily gain (ADG) than graz­ing low-quality forages; however, modest overall costs associated with grazing perennial, dormant forages may be competitive during times when feed prices are relatively high.

Gonadotropin-Releasing Hormone Increased Pregnancy In Suckled Beef Cows Not Detected In Estrus And Subjected To A Split-Time Artificial Insemination Program, S. L. Hill, D. M. Grieger, K C. Olson, J. R. Jaeger, K. R. Harmoney, C. R. Dahlen, M. R. Crosswhite, N. Negrin Pereira, S. R. Underdahl, B. W. Neville, J. Ahola, M. C. Fischer, G E. Seidel, J. Stevenson

Kansas Agricultural Experiment Station Research Reports

Estrus-synchronization programs allow insemination of all females in a herd at one fixed time on the first day of the breeding season. Inseminating cows after they have expressed estrus increases pregnancy rate (PR) compared with cows that do not display estrus in a timed AI (TAI) program. Identification of estrus status can be facilitated by using estrus-detection patches. Varying AI timing according to estrus status has increased PR in some previous studies. Reducing the number of injections in a TAI program decreases labor requirements, stress on cows, and overall cost of the program. Previous studies have demonstrated that PR is …

Effects Of Interseeding Ladino Clover Into Tall Fescue Pastures Of Varying Endophyte Status On Grazing Performance Of Stocker Steers, L. W. Lomas, J. L. Moyer

Kansas Agricultural Experiment Station Research Reports

Tall fescue, the most widely adapted cool-season perennial grass in the United States, is grown on approximately 66 million acres. Although tall fescue is well adapted in the eastern half of the country between the temperate north and mild south, presence of a fungal endophyte results in poor performance of grazing livestock, especially during the summer. Until recently, producers with high-endophyte tall fescue pastures had two primary options for improving grazing livestock performance. One option was to destroy existing stands and replace them with endophyte-free fescue or other forages. Although it supports greater animal performance than endophyte-infected fescue, endophyte-free fescue …

Effects Of Supplementation With Corn Or Dried Distillers Grains On Gains Of Heifer Calves Grazing Smooth Bromegrass Pastures, L. W. Lomas, J. L. Moyer

Kansas Agricultural Experiment Station Research Reports

Distillers grains, a by-product of the ethanol industry, have tremendous potential as an economical and nutritious supplement for grazing cattle. Distillers grains contain a high concentration of protein (25 to 30%), with more than two-thirds escaping degradation in the rumen, which makes it an excellent supplement for younger cattle. Recent advancements in the ethanol manufacturing process have resulted in extraction of a greater amount of fat; therefore, creating distillers grains that may contain less energy than corn. This research was conducted to compare performance of stocker cattle supplemented with corn or DDG at 0.5% body weight per head daily while …

Including Legumes In Bermudagrass Pastures, J. L. Moyer, L. W. Lomas

Kansas Agricultural Experiment Station Research Reports

Bermudagrass is a productive forage species when intensively managed. However, it has periods of dormancy and requires proper management to maintain forage quality. Legumes in the bermudagrass sward could improve forage quality and reduce fertilizer usage; however, legumes are difficult to establish and maintain with the competitive grass. Clovers can maintain survival once established in bermudagrass sod and may be productive enough to substitute for some N fertilization. This study was designed to compare dry cow performance on a bermudagrass pasture system that included ladino and crimson clovers (Legume) vs. bermudagrass alone (Nitrogen).

Effects Of Sodium Metabisulfite Additives On Nursery Pig Growth, D. J. Shawk, S. S. Dritz, R. D. Goodband, M. D. Tokach, J. C. Woodworth, J. M. Derouchey

Kansas Agricultural Experiment Station Research Reports

Sodium metabisulfite (SMB)-based feed additive efficacy was evaluated in 3 nursery pig growth experiments where pigs were fed diets containing low deoxynivalenol (<1.5 ppm; DON) concentrations. Pigs were weaned at approximately 22 d of age and randomly allotted to pens with one pen of 27 gilts and one pen of 27 barrows per fence line feeder, thus feeder was the experimental unit. In experiment 1, 2,268 pigs were used in a 35-d trial with 21 feeders per treatment. Experimental treatments included a control diet or the control with 0.50% SMB-based Product 1 (Defusion; Provimi, Brooksville, OH) fed in phase 1 and 0.25% fed in phases 2 and 3, then all pigs were fed a control diet for the last week of the study. Pigs fed Product 1 had greater (P<0.05) average daily gain (ADG), average daily feed intake (ADFI), and feed/gain ratio (F/G) compared to pigs fed the control diet from d 0 to 28. However, from d 28 to 35, the opposite response was observed, with pigs fed the control diet having greater ADG and improved F/G than pigs previously fed Product 1. Despite this response, pigs fed Product 1 were heavier (P<0.05) on d 35 than control-fed pigs. In experiment 2, 4,320 pigs were used in a 42-d trial with 8 or 16 feeders per treatment. Pigs were fed a control diet or diets with either SMB-based Product 1 or Product 2 (Nutriquest, Mason City, IA) at different concentrations and durations. Among the various treatments, Product 1 or Product 2 concentrations ranged from 0.50% initially to 0.25%, 0.15%, or none the last week of the study. Overall, pigs fed either of the additives at the highest concentrations and for the longest period of time had greater (P<0.05) ADG and ADFI compared to pigs fed the control diet, with those fed lower concentrations or shorter durations intermediate. In experiment 3, 2,808 pigs were used in a 28-d trial with 13 feeders per treatment. All pigs were fed a common diet for 7 d after weaning. Pigs were then either fed a control diet or diets containing Product 1 (0.50 and 0.25% from d 0 to 21 and 21 to 28 respectively), SMB (0.50 and 0.25% from day 0 to 21 and 21 to 28 respectively) or 0.25% SMB from day 0 to 28. Overall, pigs fed Product 1 or high SMB diets had greater (P<0.05) ADG compared to pigs fed low SMB or control diets. Collectively, these studies suggest that in diets with low DON concentrations, these SMB-based products increased ADG compared to pigs fed control diets.
