Daily Or Weekly Rotational Feeding Of Bovatec®- And Rumensin®/Tylan® To Cattle On A Steam-Flaked Corn Finishing Ration, Robert T. Brandt Jr. Jan 1988

Daily Or Weekly Rotational Feeding Of Bovatec®- And Rumensin®/Tylan® To Cattle On A Steam-Flaked Corn Finishing Ration, Robert T. Brandt Jr.

Kansas Agricultural Experiment Station Research Reports

One hundred sixty-five crossbred steers averaging 823 lb were utilized to evaluate the daily or weekly rotational feeding of ionophores. Treatments were (g/ton of feed, 90% dry basis): 1) Bovatec (B; 30), 2) Rumensin plus Tylan (RT; 25 and 10, respectively), 3) treatments one and two in a daily rotation (D), and 4) treatments one and two in a weekly rotation (W). Steers fed RT consumed less (P<.05) dry matter than B, D>or W steers. No differences (P>.15) in daily gain were observed, suggesting that the increased consumption by B, D) and W steers was accompanied by an al teration in passage rate …

Feedlot Performance By Steers Fed Sprout-Damaged Milo, K.P. Coffey, Lyle W. Lomas Jan 1988

Feedlot Performance By Steers Fed Sprout-Damaged Milo, K.P. Coffey, Lyle W. Lomas

Kansas Agricultural Experiment Station Research Reports

Forty-eight Charolais crossbred steers were fed sprouted or nonsprouted milo for 139 days in a finishing study. Steers fed sprouted milo (51% sprout damage, 60 lb. per bu.) were 28 lb. heavier (P<.10) and gained 8.4% faster (P<.10) while consuming 2.7% less (P>.10) feed per pound of gain. Sprout damaged milo had no significant (P>.10) effect on carcass characteristics. These data indicate that cattle fed sprouted milo should perform as well or better than those fed nonsprouted milo.

Effect Of Fat Source On Performance And Carcass Quality Of Finishing Steers, Robert T. Brandt Jr. Jan 1988

Effect Of Fat Source On Performance And Carcass Quality Of Finishing Steers, Robert T. Brandt Jr.

Kansas Agricultural Experiment Station Research Reports

Two trials that utilized 356 steers were conducted to evaluate the effects of various fat sources (3.596 of ration dry matter) on performance and carcass traits of finishing cattle fed flaked milo diets. In trial 1, soybean oil, bleachable tallow, and yellow grease (blend of tallow and restaurant grease) were compared to a nonfat control. Feeding fat increased (P<.05) daily gain, feed efficiency, carcass weight, and dressing percent of steers. Soybean oil and yellow grease also tended to increase 12th rib backfat thickness and marbling. Feed costs of gain were improved only by yellow grease. However, when increased carcass yield and quality were considered, there was a significant economic return from all fat sources. In trial 2, fat treatments were acidulated soybean soapstock (SBSS), tallow, a blend of 7096 SBSS:3096 tallow, and yellow grease. Feeding tallow or the SBSS: tallow blend improved (P<.05) feed efficiency by 7.796 compared to the nonfat control. Pooled across source, feeding fat increased (P<.10) backfat thickness and marbling. Compared to the control, feed cost of gain was reduced 6 cents/l b by the SBSS:tallow blend. However, when increased carcass value was accounted for, net returns of $3.50 to $6.00 per head were seen for SBSS, tallow, and SBSS:tallow priced at 13, 17, and 13 cents per lb, respectively. The SBSS:tallow blend provided greater performance than was predicted by observed performance of steers fed SBSS or tallow separately, an indication of associative response. In trial 2, intake and gain were lowest for yellow grease, resulting in a negative economic return, which is in complete disagreement with results obtained in trial 1.

Effect Of Tetronasin On Frothy Bloat In Cattle Caused By High-Grain Diet, L.R. Neibarger, Tiruvoor G. Nagaraja Jan 1988

Effect Of Tetronasin On Frothy Bloat In Cattle Caused By High-Grain Diet, L.R. Neibarger, Tiruvoor G. Nagaraja

Kansas Agricultural Experiment Station Research Reports

Feeding Tetronasin reduced incidence of frothy bloat in cattle fed a high-grain diet. The effective dose was 0.25 mg/kg body weight when administered prior to the onset of frothy bloat. At 0.15 mg/kg body weight, the antibiotic was less effective but the degree of bloat was considerably less than that of steers fed no antibiotic. Tetronasin also reduced the severity of bloat in steers that were already bloating prior to its administration.

Serum Cholesterol Concentrations In Yearling Bulls, G. Goldy, W. Olsen, Jack G. Riley Jan 1988

Serum Cholesterol Concentrations In Yearling Bulls, G. Goldy, W. Olsen, Jack G. Riley

Kansas Agricultural Experiment Station Research Reports

A wide range in serum cholesterol concentrations was observed within and between all four breeds of yearling bulls studied. The significance of this observation is unknown at this time. Addition research is necessary to determine the heritability of serum cholesterol, and the relationship between serum cholesterol of sires and the tissue cholesterol of their progeny.

Effect Of Grain Source And Brewer's Grain On The Performance And Serum Cholesterol Concentration Of Finishing Steers, G. Goldy, Jack G. Riley Jan 1988

Effect Of Grain Source And Brewer's Grain On The Performance And Serum Cholesterol Concentration Of Finishing Steers, G. Goldy, Jack G. Riley

Kansas Agricultural Experiment Station Research Reports

The inclusion of brewer's grains at 20% of the ration dry matter increased dry matter intake, resulting in poorer feed efficiency. Brewer's grain appeared to increase serum cholesterol. Serum cholesterol increased as days on feed increased, similar to other reported studies. Steers fed grain sorghum had greater dry matter intakes and poorer feed efficiencies than those fed barley or wheat. Analysis of tissue samples has not been completed at this time, which prohibits drawing any conclusions as to the effect on tissue cholesterol concentrations.

Testing Feedstuffs Using Near-Infrared Reflectance Spectroscopy (Nirs), P.C. Dubois, L.H. Harbers Jan 1988

Testing Feedstuffs Using Near-Infrared Reflectance Spectroscopy (Nirs), P.C. Dubois, L.H. Harbers

Kansas Agricultural Experiment Station Research Reports

Over 16 years ago, an analytical instrument was developed that could rapidly determine the concentration of organic compounds from the spectra produced by the bonding between certain molecules. The instrument is based on the principle that those molecules absorb electromagnetic radiation in the infrared region. Compounds may be quantitated by using a computer to compare absorption bands in the near-infrared spectrum to those from a large calibration set of known composition. Peaks from compounds such as water, protein, fat, and carbohydrate may be translated into nutrient components such as moisture, crude protein, crude fat, acid detergent fiber, etc. all this …

Whole-Plant Forage And Grain Sorghums And Corn Silages For Growing Cattle, B. Kirch, S. Hamma, K. Bolsen, J. Hoover, Jack G. Riley Jan 1988

Whole-Plant Forage And Grain Sorghums And Corn Silages For Growing Cattle, B. Kirch, S. Hamma, K. Bolsen, J. Hoover, Jack G. Riley

Kansas Agricultural Experiment Station Research Reports

Two trials were conducted to determine the feeding value of whole-plant forage sorghum, grain sorghum, and corn silages, with and without 25% rolled grain sorghum added to the ration. In general, growing cattle fed corn or grain sorghum silages out-performed those fed forage sorghum silages. Only forage sorghums with moderate grain yields supported gains approaching those from grain sorghum silages. With the addition of 25% rolled grain sorghum, cattle performance from the low and medium grain-yielding forage sorghum silages was improved greatly (gains by 20 to 44%, dry matter intake by 12 to 17%, feed conversion by 4 to 25%). …

Yield, Chemical Composition, And Feeding Value Of Winter Cereal Silages And Hays: A 3 Year Study, S. Azimi, K. Bolsen, A. Laytimi, S.H.M. Esmail, J. Hoover, Q.K. Ye Jan 1988

Yield, Chemical Composition, And Feeding Value Of Winter Cereal Silages And Hays: A 3 Year Study, S. Azimi, K. Bolsen, A. Laytimi, S.H.M. Esmail, J. Hoover, Q.K. Ye

Kansas Agricultural Experiment Station Research Reports

Three trials were conducted to compare silage and hay yields and feeding values of winter cereal foraged harvested in the boot and dough stages of maturity. Included were triticale; common rye; Kanby barley; and Centurk, Arkan, and Bounty 205 wheats. As expected, forage dry matter (DM) yields were higher at the dough stage then boot stage, and silage yields tended to be higher than those for hay. In Trials 2 and 3 (1986-87), barley and rye forage yields were lower than wheat yields. In all three years, wet weather conditions made hay-making difficult. In Trial 1, cattle performance from dough …

Effect Of Enzyme And Inoculant Additives On Preservation And Feeding Value Of Wheat And Forage Sorghum Silages, A. Laytimi, K. Bolsen, J. Schurhammer, B. Kirch Jan 1988

Effect Of Enzyme And Inoculant Additives On Preservation And Feeding Value Of Wheat And Forage Sorghum Silages, A. Laytimi, K. Bolsen, J. Schurhammer, B. Kirch

Kansas Agricultural Experiment Station Research Reports

Enzyme and inoculant additives produced more efficiently preserved wheat and forage sorghum silages and improved their feeding value. In general, treated silages had lower pH, acetic acid, and ammonia-nitrogen values and higher lactic acid and lactic to acetic acid ratios than untreated silages. In two of the three trials, cell wall and acid detergent fiber fractions were lower in treated than untreated silages. In Trial 2, the treated sorghum silages were extremely unstable in air and cattle performance was similar for control and treated silages. In Trial 3, gains and feed conversions in steers were improved for those fed treated …

The Effect Of Alfalfa Weevil Control On Alfalfa Hay Yield And Quality, B. Ritter, B. Bauernfeind Jan 1988

The Effect Of Alfalfa Weevil Control On Alfalfa Hay Yield And Quality, B. Ritter, B. Bauernfeind

Kansas Agricultural Experiment Station Research Reports

A 2-year-old, irriagated alfalfa field was left untreated or treated with ¼ lb, ½ lb, or 1 lb of Furadan® per acre on April 5, 1986. Alfalfa weevil populations were determined 2,9,16 and 23 days post-spraying. Forage samples were collected at about the 1/10 bloom stage of maturity. All three Furadan levels provided excellent weevil control up to 23 days post-spraying, and all resulted in an increase in dry matter yield. But only the yield of the 1 lb./A. treatment was significantly (P<.15) greater than the untreated forage (1.97 vs. 2.44 tons/A). There was no difference in nutrient composition between the untreated and treated forage. All Furadan treatment resulted in a net economic gain per acre. In this study, between ½ lb and 1 lb Furadan per acre resulted in the greatest weevil control and economic return per acre.

Effects Of Production On Reproductive Traits In Kansas Holstein Herds (1988), Edward P. Call Jan 1988

Effects Of Production On Reproductive Traits In Kansas Holstein Herds (1988), Edward P. Call

Kansas Agricultural Experiment Station Research Reports

The analysis of dairy herds to evaluate the reported negative effect of production on reproduction failed to identify a real relationship. Higher-producing herds excel in all areas of reproductive performance, except conception rate. Of greatest importance is the annual reproductive loss that is affected by the reproductive traits measured. As production per cow increased, the yearly dollar loss per cow declined from a high of $163 to $73 yearly in the group averaging 20,118 lb milk.; Dairy Day, 1988, Kansas State University, Manhattan, KS, 1988;

Cause And Control Of Hydrolytic Rancidity In Raw Milk (1988), I.J. Jeon Jan 1988

Cause And Control Of Hydrolytic Rancidity In Raw Milk (1988), I.J. Jeon

Kansas Agricultural Experiment Station Research Reports

One of the common and important off-flavors in milk is hydrolytic rancidity or lipolyzed flavor. The rancidity results from hydrolytic cleavage of fatty acids from milk fat by the enzyme lipase and their release as free acids. The release of these acids in milk, even in very small amounts, imparts a bitter taste and a sharp, unpleasant aroma. The off-flavor is often described as "goaty", "butyric", "soapy", and "bitter" The term "bitter", however, is ambiguous because bitter flavors can occur from the result of protein breakdowns. Nevertheless, both farm and dairy plant problems may lead to its development. Once an …

Errors In Heat Detection Are Costly (1988), Jeffrey S. Stevenson Jan 1988

Errors In Heat Detection Are Costly (1988), Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Attention to heat detection will decrease reproduction losses and costs associated with extended calving intervals and high culling rates. Errors in diagnosing heat (errors of commission) and missed heats (errors of omission) are the major errors of a heat detection program. Priority must be given to heat detection to improve reproductive efficiency and reduce the costs of reproductive failure on dairy farms.; Dairy Day, 1988, Kansas State University, Manhattan, KS, 1988;

Timing Of Parturition In Dairy Cattle (1988), Jeffrey S. Stevenson Jan 1988

Timing Of Parturition In Dairy Cattle (1988), Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

A recent survey of calvings of dairy heifers and cows revealed that fall calvings occurred in a nonrandom pattern. The survey was conducted in a large 5,000-cow herd in which pregnant females were watched 24 hr/day. Fewer (P<.005) calves (42%) were born during the night-time hours of darkness (6 p.m. to 6 a.m.) than during daylight hours (58%). The time of day when calving occurred was unrelated to the duration of pregnancy or to any of the climatic variables measured, including daily temperatures (highs or lows), barometric pressure, relative humidity, precipitation, average wind velocity, or percentage of sunshine. Although some reports and popular opinion have suggested that time of calving might be influenced partly by prevailing weather conditions, our data fail to support this notion. We are unable to explain the observed nonrandom pattern of calving, except that it might be influenced by other management routines on the farm.; Dairy Day, 1988, Kansas State University, Manhattan, KS, 1988;

Double Inseminations And Treatment Of Repeat Breeders With Gonadotropin-Releasing Hormone (1988), Jeffrey S. Stevenson, Edward P. Call, R.K. Scoby, A.P. Phatak Jan 1988

Double Inseminations And Treatment Of Repeat Breeders With Gonadotropin-Releasing Hormone (1988), Jeffrey S. Stevenson, Edward P. Call, R.K. Scoby, A.P. Phatak

Kansas Agricultural Experiment Station Research Reports

An experiment was conducted in one Kansas and five California dairy herds to determine if double inseminations with and without treatment with 100 µg gonadotropinreleasing hormone (GnRH) would improve conception rates of repeat-breeding dairy cattle (n=723). Both lactating cows and virgin dairy heifers were assigned randomly to treatments as repeat breeders, if they had failed to conceive to at least two previous services. Cows inseminated once and treated with GnRH had the best conception rates (41%), which were higher (P<.OI) than those of cows inseminated once without GnRH treatment (32%) and higher (P<.OI) than those of cows inseminated twice without treatment with GnRH (33%). Cattle bred twice that received the GnRH treatment had intermediate rates (37%). We conclude that treatment of repeat breeders with GnRH at the time of insemination (only one service given according to the am-pm, pm-am rule) improved conception rates.; Dairy Day, 1988, Kansas State University, Manhattan, KS, 1988;

The Evaluation Of Rapid Methods For Monitoring Free Fatty Acid Levels In Cheese (1988), W.G. Ikins, H.S. Kwak, G.S. Zink, I.J. Jeon Jan 1988

The Evaluation Of Rapid Methods For Monitoring Free Fatty Acid Levels In Cheese (1988), W.G. Ikins, H.S. Kwak, G.S. Zink, I.J. Jeon

Kansas Agricultural Experiment Station Research Reports

The amount of free fatty acids present in cheese is important to dairy processors because these compounds make a significant contribution to the overall flavor. In this study, the results obtained using three relatively rapid methods of determining free fatty acids concentrations in cheese were compared to those acquired by using a more laborious but accurate gas chromatographic technique. One method, the Extraction-Titration Method, was found to be superior to the others because of its simplicity and reliability. In addition, the values obtained by this method were found to closely correlate with short chain fatty acid concentrations of cheese as …

Early Postpartum Luteal Function After Treatment With Progestin And(Or) Gonadotropin-Releasing Hormone In Dairy Cattle (1988), M.O. Mee, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Progestin (Norgestomet®) and(or) repeated low-dose infusions of GnRH (Cystorelin@) influenced the lifespan of the first corpus luteum after an induced ovulation. Holstein cows (n=32) were assigned at calving to four groups. Cows were treated with blank ear implants (days 2 to 9 after calving) and saline infusion (48 hr on days 10 arid II), progestin ear implants and saline infusion, blank implants and GnRH infusion, or progestin implants and GnRH infusion prior to a GnRH-induced ovulation (day 12). Four primiparous and four multiparous cows were assigned to each treatment. Fewer cows treated with progestin/GnRH ovulated in response to the GnRH …

Sunflower Oil Seeds In Nursery Pig Diets (1988), G E. Fitzner, Robert H. Hines Jan 1988

Sunflower Oil Seeds In Nursery Pig Diets (1988), G E. Fitzner, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Two hundred forty pigs were used to evaluate the use of various amounts (0, 10, 15, 20, 25%) of black sunflower oil seeds in weanling pig diets. After 14 days, no significant differences were found between any of the dietary treatments in feed intake (FI), average daily gain (ADG), or feed efficiency (F/G). At the conclusion of the 5-wk study, no differences were found in FI, ADG, or F/G between those dietary treatments containing 0, 10, and 15% sunflower seeds. However, in those diets containing 20 and 25% sunflower seeds, there were linear (p<.05) reductions in FI and ADG. These results indicate that sunflower seeds, when finely ground using a hammermill with a 1/8 in screen, can be used in diets for weanling pigs up to 15% of the diet with no reduction in performance.; Swine Day, Manhattan, KS, November 17, 1988

Hog Feeders? (1988), Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

During the past 6 yr, extensive research has been conducted at KSU to evaluate feeding systems and various types of wet and dry feeders. Comparisons have been made between timed-feeding and ad libitum feeding systems using dry or wet feeders. Timed-feeding did not improve pig performance (ADG, F/G) when compared with ad libitum dry feeding. Wet feeding in most of the trials resulted in approximately 5% improvement in both average daily gain and feed efficiency. Feeding hogs with an oval or rectangular dry feeder resulted in similar pig performance. A11 feeders were easily adjusted to reduce feed wastage to a …

Comparison Of Wet Versus Dry Feeding For Starter Pigs (1988), R C. Thaler, Jim L. Nelssen Jan 1988

Comparison Of Wet Versus Dry Feeding For Starter Pigs (1988), R C. Thaler, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

Two studies utilizing a total of 480 pigs (21 days old) were conducted to compare wet versus dry feeding during a 4 wk starter period. Pigs were fed a pelletized, high nutrient density diet for the first 2 wk and a semi-complex diet (meal form) for the last 2 wk. Aqua® feeders were used in all pens. During the first 2 wk of the study, feeding method had no effect on daily gain or feed intake; however, pigs fed dry diets required less feed per pound of gain than did pigs consuming wet diets (P<.0002). For the overall 4 wk trial, gains and feed intake did not differ between treatments, but pigs fed the wet diets were less efficient than pigs receiving the dry diets. Based on these results, wet feeding is not advantageous to starter pig performance.; Swine Day, Manhattan, KS, November 17, 1988
