A Comparison Of Raw Soybeans And Soybean Oil As Energy Sources For Finishing Pigs (1987), Robert D. Goodband, Robert H. Hines, R C. Thaler Jan 1987

A Comparison Of Raw Soybeans And Soybean Oil As Energy Sources For Finishing Pigs (1987), Robert D. Goodband, Robert H. Hines, R C. Thaler

Kansas Agricultural Experiment Station Research Reports

Two hundred and seventy pigs averaging 125 lbs were utilized in two growth trials to determine the effects of raw soybeans or soybean oil on finishing pig performance. In each trial, raw soybeans or soybean oil were substituted for milo to provide 2 or 3% added fat. Pigs fed these diets were compared to pigs fed a milo-soybean meal diet (control). In Experiment 1, raw soybeans or soybean oil were added in place of milo in a 15% crude protein, .7% lysine diet. Increasing levels of raw soybeans resulted in greater trypsin inhibitor content compared to the control or soybean …

The Value Of Drip Versus Spray Cooling At Two Flow Rates To Reduce Heat Stress Of Finishing Swine (1987), David A. Nichols, R C. Thaler, James P. Murphy, Robert H. Hines, Jim L. Nelssen Jan 1987

The Value Of Drip Versus Spray Cooling At Two Flow Rates To Reduce Heat Stress Of Finishing Swine (1987), David A. Nichols, R C. Thaler, James P. Murphy, Robert H. Hines, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

One hundred fifty pigs were used to evaluate the effectiveness of either spray cooling or drip sprinkling to reduce heat stress in finishing swine. In addition, water flow rates of .2 gal/pig/hr and .4 gal/pig/hr were compared. All wetting treatments significantly (P<.01) improved average daily gain and feed intake (P<.05) compared with non-wetted control. No differences were observed in feed to gain ratio among treatments. Drip sprinkling at the higher flow rate resulted in performance equal to that with intermittent spray cooling at both flow rates.; Swine Day, Manhattan, KS, November 19, 1987

Effects Of Milk Products (Casein And Lactose) On Nutrient Digestibility In Weaned Pigs Fed A High Fat Dry Diet (1987), W H. Turlington, G L. Allee, Jim L. Nelssen Jan 1987

Effects Of Milk Products (Casein And Lactose) On Nutrient Digestibility In Weaned Pigs Fed A High Fat Dry Diet (1987), W H. Turlington, G L. Allee, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

Two trials using a total of 48 pigs were conducted to compare protein (soybean meal and casein) and carbohydrate (dextrose and lactose) sources. In trial 1, digestion studies were conducted to determine apparent digestible energy content of the four treatments and apparent nutrient digestibility coefficients. In trial 2, pigs were sacrificed to determine ileal and total tract (apparent) nutrient digestibility coefficients. Results suggest that milk products are important to improving energy and nutrient digestibility in the young pig. The younger the pig or the sooner after weaning, the greater the benefit from their addition. The data also suggest that milk …

Effects Of Flushing, Altrenogest, And Pubertal Status On Litter Traits In Gilts (1987), M T. Rhodes, Duane L. Davis, Jeffrey S. Stevenson Jan 1987

Effects Of Flushing, Altrenogest, And Pubertal Status On Litter Traits In Gilts (1987), M T. Rhodes, Duane L. Davis, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

We tested the effects of flushing (3.4 lb extra ground sorghum grain for at least 10 days before estrus) and estrous synchronization with altrenogest on litter traits in gilts. Altrenogest had no effect on litter size or weight, but flushing increased both traits. The response to flushing occurred entirely among gilts artificially inseminated at the pubertal estrus. Pubertal gilts represented approximately 40% of the gilts in our experiment, and their improvement in litter size was almost two pigs. When all gilts were considered, flushing improved litter size by .9 pigs.; Swine Day, Manhattan, KS, November 19, 1987

Effect Of Fat Source On Performance Of Weaned Pigs (1987), W H. Turlington, G L. Allee, Jim L. Nelssen Jan 1987

Effect Of Fat Source On Performance Of Weaned Pigs (1987), W H. Turlington, G L. Allee, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

A 5-week trial was conducted to compare various fat sources for the weaned pig. A total of 150 pigs were weaned at 19 days of age and allotted, by weight, to five dietary treatments. Treatments consisted of a control with no added fat and four fat sources (choice white grease, coconut oil, soybean oil and tallow). During the first 2 weeks, 10% fat was added, and 5% fat was added during the last 3 weeks. Average daily gain and feed/gain of weaned pigs were improved with the addition of dietary fat. During the first 2 weeks, pigs fed soybean oil …

Characteristics Of Frankfurters From Preblended Pork (1987), Curtis L. Kastner, Y I. Choi, Donald H. Kropf Jan 1987

Characteristics Of Frankfurters From Preblended Pork (1987), Curtis L. Kastner, Y I. Choi, Donald H. Kropf

Kansas Agricultural Experiment Station Research Reports

Five pork carcasses were used to determine the effects of hot boning and various combinations of salt (0, 1.5, or 3.0%) and a phosphate mixture (0 or 0.5%) on functional, processing, and storage characteristics of preblended pork (preblends). Although hot-boned (HB) preblends had superior functional properties compared to conventionally boned (CB) preblends, HB and CB frankfurters had similar characteristics. More (P(.05) myosin and actin (proteins that cause lean and fat particles to bind together) were extracted from HB than CB preblends. Addition of salt (1.5 or 3.0%) or phosphate (0.5%) generally increased myosin and actin extraction in both HB and …

Protein Requirement Of Finishing Barrows And Gilts (110 To 230 Lbs) (1987), Robert H. Hines, B A. Koch, David A. Nichols, L M. Turlington, Robert D. Goodband Jan 1987

Protein Requirement Of Finishing Barrows And Gilts (110 To 230 Lbs) (1987), Robert H. Hines, B A. Koch, David A. Nichols, L M. Turlington, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

Eighty barrows and 80 gilts were fed diets containing four crude protein levels (16, 15, 14, and 13%) from approximately 115 lb to a market weight of 230-235 lb. Barrows and gilts were fed separately to determine their protein requirements during the finishing period. Performance traits (ADG, ADF, and F/G) of barrows and gilts were not significantly affected by increasing the protein content of the diet from 13 to 16%. However, barrows linearly decreased in fat thickness at the 10th rib as crude protein content in the diet was increased. Also, percent muscle increased linearly with increased protein for barrows, …

How Important Is Extra Solids-Not-Fat In Your Milk? (1987), H.A. Roberts Jan 1987

How Important Is Extra Solids-Not-Fat In Your Milk? (1987), H.A. Roberts

Kansas Agricultural Experiment Station Research Reports

Milk with high solids-not-fat is valuable to the consumer for its flavor and nutritional value and to the manufacturer of milk products, especially relating to cheese yield. Solids-not-fat consists of all solids in milk other than fat. Protein is the most important component of milk because of its nutritional value and its functional properties. Other components, such as milk fat and lactose, also contribute to milk quality and impart certain characteristics to milk products but to a lesser degree.; Dairy Day, 1987, Kansas State University, Manhattan, KS, 1987;

Effect Of Production On Reproduction (1987), Edward P. Call Jan 1987

Effect Of Production On Reproduction (1987), Edward P. Call

Kansas Agricultural Experiment Station Research Reports

The genetic antagonsim that exists between production and reproduction is overcome by sound management practices. Kansas Holstein herds were ranked by quartile and analyzed by comparing various reproductive traits. Higher producing herds suffered less reproductive loss based upon the factors considered. The most significant differences concerned the average days dry, average days open on cows not yet serviced, percent of cows open more than 120 days since fresh, and average age at first calving. An adequate record system will identify potential reproductive problems, and a sound Preventive Herd Health Program (PHHP) will minimize actual losses from disease and cows not …

Gonadotropin-Releasing Hormone Improves Conception Rates Of Repeat-Breeders With Previous Reproductive Disorders (1987), Jeffrey S. Stevenson, Edward P. Call Jan 1987

Gonadotropin-Releasing Hormone Improves Conception Rates Of Repeat-Breeders With Previous Reproductive Disorders (1987), Jeffrey S. Stevenson, Edward P. Call

Kansas Agricultural Experiment Station Research Reports

An experiment examining the benefit of treating repeat-breeders with 100 µg GnRH (Cystorelin ®) at the time of third or fourth insemination was conducted in 513 dairy cows of which 93 (abnormal cows) had been diagnosed previously (during the 60 to 90 days postpartum) as having reproductive disorders, including retained placenta, uterine infections, prolonged anestrus, and cystic ovaries. Treatment with GnRH improved conception in normal and abnormal repeat-breeding cows by 13 percentage points or 42%.; Dairy Day, 1987, Kansas State University, Manhattan, KS, 1987;

Influence Of Prebreeding Progesterone Plus Prostaglandin F2-Α On Estrus And Fertility In Lactating Dairy Cows (1987), M.O. Mee, R.E. Stewart, Jeffrey S. Stevenson, Edward P. Call Jan 1987

Influence Of Prebreeding Progesterone Plus Prostaglandin F2-Α On Estrus And Fertility In Lactating Dairy Cows (1987), M.O. Mee, R.E. Stewart, Jeffrey S. Stevenson, Edward P. Call

Kansas Agricultural Experiment Station Research Reports

Progesterone administered before breeding may increase estrous expression and subsequent fertility in lactating dairy cows. Holstein cows (n=302) were assigned randomly at calving to three groups. Cows received no treatment (controls), one injection of prostaglandin F 2-α (PGF), or progesterone plus one injection of PGF (PRID + PGF). The average interval to estrus was 5 days shorter in PRID + PGF cows compared to cows given only PGF. In addition, more cows were observed in estrus 2 to 5 days after treatment in the PRID + PGF group compared to the PGF group. Average days from calving to conception were …

Effect Of Supplemental Potassium And Buffer In Starters For Early-Weaned Calves (1987), P. Flynn, J.L. Morrill, P.G. Reddy, James J. Higgins Jan 1987

Effect Of Supplemental Potassium And Buffer In Starters For Early-Weaned Calves (1987), P. Flynn, J.L. Morrill, P.G. Reddy, James J. Higgins

Kansas Agricultural Experiment Station Research Reports

Sixty Holstein heifers were used from birth to 8 weeks of age to study the effect of amount of potassium (K) in the diet and of adding a buffer to the starter. Starters were formulated with and without 1% trona, a natural ore buffer, at K concentrations of .9, 1.25, and 1.5% of the dry matter. To supply adequate fiber, yet allow formulation of the starter containing .9% K, 20% prairie hay was included. All calves were fed milk and a prestarter, using an early weaning procedure. Growth and feed consumption data and evaluation of health and metabolic activity were …

Kansas Agricultural Experiment Station Research Reports

Oil-extracted, desolveritized soy flour without additional heat treatment was used to prepare protein supplements for calf milk replacers by extrusion processing. Various combinations of temperature, moisture, calcium concentration, sulfur, and acid were used to prepare 32 different products. These products were tested for trypsin inhibitor and antigenic activity and the most promising one was chosen for further testing. This product alone or with supplementary amino acids or amino acids and citric acid was used to provide 70% of the protein in experimental milk replacers. These replacers were compared to an all-milk replacer, using growth and metabolic responses of young Holstein …

Early Lactation Somatic Cell Count Should Be Low (1987), James R. Dunham Jan 1987

Early Lactation Somatic Cell Count Should Be Low (1987), James R. Dunham

Kansas Agricultural Experiment Station Research Reports

Cows and heifers in milk for fewer than 50 days, as shown on the DHIA Somatic Cell Count report, should have a lower average Somatic Cell Count than cows in milk for more than 300 days, if the dry cow mastitis treatment and management programs are effective. The DHIA Somatic Cell Count (SCC) average for a dairy herd is a good evaluation of a mastitis control program. Since leucocytes migrate to the mammary system during periods of subclinical mastitis, the SCC average indicates the amount of subclinical mastitis in a herd. A realistic goal for a herd average SCC is …

Estrous Expression Of Sows After Altered Suckling And Boar Exposure (1987), E A. Newton, Jeffrey S. Stevenson, Duane L. Davis Jan 1987

Estrous Expression Of Sows After Altered Suckling And Boar Exposure (1987), E A. Newton, Jeffrey S. Stevenson, Duane L. Davis

Kansas Agricultural Experiment Station Research Reports

In two different experiments, we studied the influence of: 1) separating litters from their dams (altered suckling) during the last 8 days of lactation, which included a change in housing and social interaction with other sows; 2) providing boar exposure (1 hr/d); and 3) parity on the ability of sows to come into heat during lactation and after weaning. Our studies indicated that: 1) 6 hr of altered suckling and 1 hr of boar exposure may shorten the interval to heat for sows that express estrus during lactation, but 3 hr of altered suckling and 1 h of boar exposure …

Effects Of Trenbolone Acetate And Zeranol Implants On Performance, Carcass, And Meat Traits Of Young Bulls And Steers (1987), R.D. Johnson, Michael E. Dikeman Jan 1987

Effects Of Trenbolone Acetate And Zeranol Implants On Performance, Carcass, And Meat Traits Of Young Bulls And Steers (1987), R.D. Johnson, Michael E. Dikeman

Kansas Agricultural Experiment Station Research Reports

Implanting young bulls and steers with trenbolone acetate and zeranol (Ralgro ®) resulted in increased slaughter weights and carcasses that tended to have more marbling than those of control bulls. Furthermore, steaks from both implanted bulls and implanted steers tended to have less detectable connective tissue. Control bulls had larger scrotal circumferences and heavier testicle weights than implanted bulls. Other secondary sex characteristics were not affected, but in these bulls slaughtered at an average age of 13.6 months, sexual development was minimal. Implanting steers with trenbolone acetate and zeranol resulted in performance and carcass and meat quality slightly superior to …

Efficacy Of Depo-Mga® In Feedlot Heifers (1987), Jack G. Riley, Ronald V. Pope, L. O'Neill

Kansas Agricultural Experiment Station Research Reports

Three levels of melengestrol acetate (30, 60, and 90 mg) injected subcutaneously as a liquid (DEPO-MGA ®) in the ear of heifers yielded high performance results comparable to feeding 0.5 mg of MGA per head daily. Heifers fed 0.5 mg MGA daily gained 6% faster and were 11% more efficient than heifers not receiving MGA. This study will be pooled with trials from 13 other locations in the U.S. to determine if further development and FDA clearance of DEPO-MGA ® will be pursued by the Upjohn Company.

Color Formation And Retention In Fresh Beef (1987), Donald H. Kropf, Melvin C. Hunt, D. Piske Jan 1987

Color Formation And Retention In Fresh Beef (1987), Donald H. Kropf, Melvin C. Hunt, D. Piske

Kansas Agricultural Experiment Station Research Reports

We conducted two studies in response to a severe problem with ground beef color encountered by beef fabricators and retailers. We concluded that: (1) Loss of muscle chemical-reducing capability upon grinding, with subsequent color deterioration, results from both the mechanical effect of grinding and incorporation of oxygen into the beef. (2) Flat, thin, surface muscles from beef carcasses retain more ability to bloom (turn bright red) if they are removed by hot boning or after a relatively short chill period.

Whole-Plant Forage And Grain Sorghum Silages For Growing Cattle (1987), B. Kirch, S. Hamma, K. Bolsen, H. Ilg, J. Hoover Jan 1987

Whole-Plant Forage And Grain Sorghum Silages For Growing Cattle (1987), B. Kirch, S. Hamma, K. Bolsen, H. Ilg, J. Hoover

Kansas Agricultural Experiment Station Research Reports

Four trials were conducted to determine the feeding value of whole-plant forage and grain sorghum silages. In general, growing cattle fed grain sorghum hybrids (NK2778, Funk's 550, DeKalb 42Y, DeKalb E67) out performed those fed forage sorghum silages. Only moderate to high grain-content, forage sorghums (Buffalo Canex, Pioneer 947, Acco 351) gave performances that approached the grain sorghums. Low grain-content and nonheading forage sorghums (DeKalb 25E, Funk's G-1990) resulted in the poorest cattle performance. These studies indicate that grain content of a sorghum silage is the major determinant of cattle performance and that whole-plant grain sorghums should produce the fastest …

Additive-Treated Corn Silages For Growing Cattle (1987), K. Bolsen, H. Ilg, B. Kirch, A. Laytimi, Lyle W. Lomas Jan 1987

Additive-Treated Corn Silages For Growing Cattle (1987), K. Bolsen, H. Ilg, B. Kirch, A. Laytimi, Lyle W. Lomas

Kansas Agricultural Experiment Station Research Reports

Whole-plant corn silages were treated with USO3M or Silo-Best Soluble® in one trial and with Garst M-74® in a second trial. In Trial 1 all three silages were well preserved and moderately stable in the air. USO3M silage lost less dry matter during fermentation than control or Silo-Best silages. Cattle fed the USO3M silage made 7.6% faster gains and were 5.2% more efficient than those fed the control silage. Cattle performance with the Silo-Best Soluble and control silages was similar. In trial 2, heifer gains were nearly identical for both control and Garst M-74 silages.

Grazing And Feedlot Performance Of Heifers Spayed By Two Methods (1987), S.B. Laudert, Gerry L. Kuhl, A.J. Edwards Jan 1987

Grazing And Feedlot Performance Of Heifers Spayed By Two Methods (1987), S.B. Laudert, Gerry L. Kuhl, A.J. Edwards

Kansas Agricultural Experiment Station Research Reports

Two field trials were conducted to compare the pasture and finishing performance of heifers spayed by the Kimberling-Rupp(K-R) technique or by flank spaying plus autografting a piece of ovarian tissue into the rumen wall (FS+A). In trial 1, neither spaying method resulted in gains of grazing heifers different from that of intake controls; however, FS+A heifers gained 5.1% faster than K-R spayed heifers. In trial 2, grazing gains of heifers spayed by the two techniques were similar. During the finishing phase, no performance difference was found among intact, K-R, or FS+A heifers in trial 1 or between K-R and FS+A …

Influence Of Sorghum Grain Supplementation On Forage Utilization By Beef Steers Consuming Immature Bluestem (1987), E.S. Vanzant, A.A. Beharka, R.C. Cochran, T.B. Avery, K.A. Jacques Jan 1987

Influence Of Sorghum Grain Supplementation On Forage Utilization By Beef Steers Consuming Immature Bluestem (1987), E.S. Vanzant, A.A. Beharka, R.C. Cochran, T.B. Avery, K.A. Jacques

Kansas Agricultural Experiment Station Research Reports

Supplementing beef steers consuming immature bluestem with 0, 1, 2, or 4 lbs of sorghum grain daily did not affect forage intake. Thus, total intake increased as level of grain increased. Total dry matter, cell wall, and starch digestibilities were mildly depressed with increasing grain. Rumen fill and rates of passage were similar for all treatments, and differences in rumen fermentation characteristics were minimal.

Effects Of Preweaning And Postweaning Implants On Suckling, Growing, And Finishing Steer Performance - A Three Trial Summary (1987), D.D. Simms, T.B. Goehring, R.W. Lee, Robert T. Brandt Jr., S.B. Laudert, Gerry L. Kuhl Jan 1987

Effects Of Preweaning And Postweaning Implants On Suckling, Growing, And Finishing Steer Performance - A Three Trial Summary (1987), D.D. Simms, T.B. Goehring, R.W. Lee, Robert T. Brandt Jr., S.B. Laudert, Gerry L. Kuhl

Kansas Agricultural Experiment Station Research Reports

Over 500 crossbred steers were used in three trials to compare lifetime implant strategies and to study the effects of implanting during the suckling period on performance in the growing and finishing periods. Contrary to previous research, implanting in the suckling period did not increase suckling gain. Implanting in the growing period increased (P<.05) average daily gain, and the implant response in the growing period was not influenced by suckling implant treatment. Steers implanted twice during the finishing period had similar finishing gains regardless of prior implant treatment. Steers implanted only once during the finishing phase gained less (P<.05) than those implanted twice, and while their gains were higher than those of control steers, the difference was small (P>.05). Implanting steers in the finishing phase tended to improve feed conversion but again the difference was not statistically significant. All implant treatments increased (P<.05) lifetime average daily gains and total gain, and there was no difference among implant combinations. Implant treatments increased lifetime gains by 30 to 54 lbs. Because implanting in the suckling period did not reduce cattle performance during the growing and finishing periods, there appears to be no basis for discounting the price of previously implanted cattle. Additionally, this study emphasizes the importance of reimplanting cattle during long finishing periods

Dry Cow Management Program (1987), John F. Smith Jan 1987

Dry Cow Management Program (1987), John F. Smith

Kansas Agricultural Experiment Station Research Reports

Dry cows do not require the intensive daily management of cows in early lactation, but the handling of mastitis treatments, feeding regimen, and grouping are of utmost importance in determining how the cows will perform in the subsequent lactation. The dry period is the time we allow for the cow to regenerate milk-secreting tissue, combat mastitis, and prepare for the next lactation. The body condition of each cow should be moderate before drying off. Each quarter should be treated with a commercial dry cow mastitis treatment, then the cow should be separated from the milking herd for observation and fed …

Evaluation Of A Calf Starter Supplement (1987), J.L. Morrill, P.G. Reddy

Kansas Agricultural Experiment Station Research Reports

An experimental calf starter made from a pelleted commercial type supplement and feeds readily available on the farm was compared to a conventional pelleted calf starter in an attempt to demonstrate an economical alternative to commercial calf starter. Calves fed the experimental starter consumed as much starter and gained as much weight as calves fed the conventional starter, thus demonstrating a potential for savings on feed cost. The project is continuing in an attempt to improve the starter composition.; Dairy Day, 1987, Kansas State University, Manhattan, KS, 1987;
