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

Color Formation And Retention In Fresh Beef, 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.

Influence Of Ionophore Addition To A High-Concentrate Diet On Net Nutrient Absorption In Steers, D.L. Harmon, K.L. Gross, T.B. Avery Jan 1987

Influence Of Ionophore Addition To A High-Concentrate Diet On Net Nutrient Absorption In Steers, D.L. Harmon, K.L. Gross, T.B. Avery

Kansas Agricultural Experiment Station Research Reports

Feeding the ionophores monensin and lasalocid In a high-concentrate diet resulted in gut tissues utilizing less glucose. Monensin caused less urea to be recycled. The new, experimental ionophore (lCI 139603) resulted in an increased net absorption of acetate. Thus, ionophores may differ in how they execute their effects on feed efficiency.

Effects Of Energy Level And Lasalocid On Productivity Of Fall-Calving, First-Calf Heifers, T. Goehring, L. Corah, James J. Higgins Jan 1987

Effects Of Energy Level And Lasalocid On Productivity Of Fall-Calving, First-Calf Heifers, T. Goehring, L. Corah, James J. Higgins

Kansas Agricultural Experiment Station Research Reports

Fall-calving, first-calf heifers (136 head) were fed TDN levels approximating 85% or 100% of NRC recommendations, with or without 200 mg/hd/day lasalocid. Those fed the recommended diet gained more weight from 130 days prepartum to calving and showed more improvement in condition score before calving than those on the low-energy diet. After calving, the group fed the recommended energy level lost less weight and condition and had better reproductive performance than the low-energy group. The only effect of lasalocid was to improve calf performance in the low-energy group.

Relationship Of Age At Puberty And Postpartum Interval To Estrus In Angus X Hereford And Brahman X Hereford Females, D.J. Patterson, L.R. Corah, J.R. Brethour, W.R. Negus Jan 1987

Relationship Of Age At Puberty And Postpartum Interval To Estrus In Angus X Hereford And Brahman X Hereford Females, D.J. Patterson, L.R. Corah, J.R. Brethour, W.R. Negus

Kansas Agricultural Experiment Station Research Reports

Records of age at puberty (AAP) and postpartum interval to estrus (PPI) for heifers calving first at 2 years of age were used to determine the relationship between the two reproductive parameters. In Brahman x Hereford (BxH) females, there was no relationship between AAP and PPJ. In Angus x Hereford (AxH) females, PPI increased as AAP decreased. The data suggest that heifers heavier at weaning reach puberty younger, but PPJ may be longer following their first calving. Heifers larger at weaning may need to be managed differently to improve performance during the first postpartum period.

Calving And Reproductive Performance Of Angus X Hereford And Brahman X Hereford Heifers Fed To Prebreeding Target Weights, D.J. Patterson, L.R. Corah, J.R. Brethour, W.R. Negus Jan 1987

Calving And Reproductive Performance Of Angus X Hereford And Brahman X Hereford Heifers Fed To Prebreeding Target Weights, D.J. Patterson, L.R. Corah, J.R. Brethour, W.R. Negus

Kansas Agricultural Experiment Station Research Reports

The effect of heifer development on first calving and subsequent reproductive performance was evaluated in Angus x Hereford (AxH) and Brahman x Hereford (BxH) females. Heifers were fed to reach either 55% or 65% of their projected mature body weight by the start of their first breeding season. After breeding, the heifers were managed as a typical commercial range beef cow herd. Angus x Hereford heifers developed to the higher prebreeding target weights: 1) were heavier (P<.05) at calving; 2) had larger (P<.05) total precalving pelvic areas; and 3) had higher (P<.05) average postcalving body condition scores. Precalving pelvic areas were also greater (P<.05) among BxH females developed to the higher prebreeding target weight. Angus x Hereford heifers fed to the low target weight experienced 23.5% more calving problems (52.3 vs 28.8%). Only 11.3% of the BxH heifers required assistance at calving, and calving difficulty was not related to nutritional level. Postpartum interval to estrus (PPJ) was longer among low target AxH heifers, but not in BxH heifers. Calf weaning weight was not affected by heifer development; however, weights were heavier for calves raised by the BxH heifers. These data suggest that differences in weight and condition prior to first breeding persist through to the heifer's first calving and postpartum period.

Effects Of Mga And Prostaglandin On Estrus Induction And Synchronization In Cows And Heifers, R.C. Perry, G.W. Boyd, T.B. Goehring, L.R. Corah Jan 1987

Effects Of Mga And Prostaglandin On Estrus Induction And Synchronization In Cows And Heifers, R.C. Perry, G.W. Boyd, T.B. Goehring, L.R. Corah

Kansas Agricultural Experiment Station Research Reports

Four trials were conducted to evaluate the effectiveness of Melegestrol Acetate (MGA ®) and prostaglandin (PGF) in inducing and synchronizing estrus. In trial 1, treated heifers were fed MGA for 7 days and given a PGF injection on either the first or last day of MGA feeding. The 7-day estrus response was higher (P<.01) for treated heifers than untreated controls. In trial 2, treated cows were fed MGA for 7 days and given a PGF Injection on the last day of MGA feeding or 13 days after the last day of MGA feeding. The 7-day estrus response was also higher (P<.01) in treated cows. In trial 3, 59 cows were fed MGA for 7 days followed by a PGF injection, and exposed to bulls for 66 days. The MGA-PGF treatment was ineffective in synchronizing estrus and hastening conception. In trial 4, feeding MGA for 7 days successfully synchronized estrus in. cycling cows, but first service conception rates were reduced by 10% in the Kansas study and by 16% in a four state study.

Effect Of Commercial Inoculants On The Fermentation Of Alfalfa, Corn, Forage Sorghum, And Triticale Silages, K. Bolsen, H. Ilg, A. Laytimi, R. Hart, V. Chain, L. Nuzback, Daniel Y.C. Fung Jan 1987

Effect Of Commercial Inoculants On The Fermentation Of Alfalfa, Corn, Forage Sorghum, And Triticale Silages, K. Bolsen, H. Ilg, A. Laytimi, R. Hart, V. Chain, L. Nuzback, Daniel Y.C. Fung

Kansas Agricultural Experiment Station Research Reports

Fourteen commercial inoculants were evaluated in seven trials using alfalfa, corn, forage sorghum, and triticale silages. Microbial profiles of the inoculants and of the crops differed widely. Viable lactic acid bacteria (LAB) supplied per gram of fresh crop by the inoculants ranged from less than 103 to over 103. Only the alfalfas had 10 or fewer LAB per gram of crop when the forages were treated and as a result, fermentation responses were excellent for those inoculants that supplied 10 or more LAB per gram of treated crop. Corn and triticale underwent a very rapid fermentation rate with very little …

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

Additive-Treated Corn Silages For Growing Cattle, 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.

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

Whole-Plant Forage And Grain Sorghum Silages For Growing Cattle, 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 …

Evaluation Of Stocking Rate, Compudose® Implants, And Rumensin® Ruminal Delivery Devices Within Intensive-Early Stocking, R.C. Cochran, Jack G. Riley, Clenton E. Owensby, G. Towne, E.S. Vanzant, Ronald V. Pope Jan 1987

Evaluation Of Stocking Rate, Compudose® Implants, And Rumensin® Ruminal Delivery Devices Within Intensive-Early Stocking, R.C. Cochran, Jack G. Riley, Clenton E. Owensby, G. Towne, E.S. Vanzant, Ronald V. Pope

Kansas Agricultural Experiment Station Research Reports

Stocking rate in an intensive-early stocking system (1.25, 1.50, or 1.76 acres per steer) did not influence steer gains. Available forage on loamy upland sites was lower after steer removal on July 15 for the highest stocking rate. However, after late season rest, available forage was similar for all stocking rates. Steer gains were consistently greater for groups implanted with Compudose® (estradiol 78β or Compudose plus a Rumensin® (monensin) ruminal delivery device. The Rumensin device alone was successful in increasing average daily gain only at the highest stocking rate.

Effect Of Maturity At Harvest On Yield, Composition, And Feeding Value Of Forage And Grain Sorghum Silages, S. Hamma, B. Kirch, B. Downey, J. White, K. Bolsen

Kansas Agricultural Experiment Station Research Reports

In the last 2 years, three trials were conducted to determine the influence of hybrid and stage of maturity at harvest on silage yield, composition, and nutritive value for 15 forage and nine grain sorghum hybrids. Agronomic data, such as days to half bloom, plant height, and whole-plant dry matter (OM) and grain yields, were also obtained. In Trial 1, Pioneer 947, Acco Paymaster 351, and DeKalb 25E forage sorghum hybrids had different whole-plant OM and crude protein (CP) contents. Whole-plant OM increased, whereas CP generally decreased with advancing maturity. Hybrid affected both DM intake and CP digestibility. Results indicated …

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

Grazing And Feedlot Performance Of Heifers Spayed By Two Methods, 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 …

Implant Comparisons In Grazing And Finishing Spayed Heifers, S.B. Laudert, Gerry L. Kuhl, A.J. Edwards Jan 1987

Implant Comparisons In Grazing And Finishing Spayed Heifers, S.B. Laudert, Gerry L. Kuhl, A.J. Edwards

Kansas Agricultural Experiment Station Research Reports

Heifers that were flank-spayed plus rumen-ovarian autografted (FS+A) responded similarly to Ralgro®, Synovex-H®, and Synovex-S® implants on' pasture. Grazing heifers spayed by the Kimberling-Rupp technique also responded similarly to Synovex-H and Synovex-S implants. During the finishing phase, heifers implanted with Synovex-S gained 5.7% faster than heifers implanted with Ralgro, and those implanted with Synovex-H were intermediate in performance. There was no statistical interaction between spaying method and implant treatment during either the grazing or finishing phases.

Effect Of Several Spaying Methods On Grazing Heifer Gains, Gerry L. Kuhl, T. Goehring, B. Ritter, S. Laudert, W. Mccully Jan 1987

Effect Of Several Spaying Methods On Grazing Heifer Gains, Gerry L. Kuhl, T. Goehring, B. Ritter, S. Laudert, W. Mccully

Kansas Agricultural Experiment Station Research Reports

Several spaying and ovarian autografting methods were tested in three field trials with 658 grazing heifers. None of the techniques examined were found to have a beneficial effect on heifer gains compared to intact controls. Heifers' initial weight, frame size, and body condition score were associated with cattle performance; however, their relative impact on gains varied across the three trials.

Effect Of Supplemental Protein:Energy Ratio On The Intake, Digestibility, Fill, And Turnover Of Dormant Bluestem Range-Grasses, T. Delcurto, R.C. Cochran, K.A. Jacques, D.L. Harmon, G. Towne, T.B. Avery, E.S. Vanzant Jan 1987

Effect Of Supplemental Protein:Energy Ratio On The Intake, Digestibility, Fill, And Turnover Of Dormant Bluestem Range-Grasses, T. Delcurto, R.C. Cochran, K.A. Jacques, D.L. Harmon, G. Towne, T.B. Avery, E.S. Vanzant

Kansas Agricultural Experiment Station Research Reports

Feeding a low crude protein (12%) supplement depressed dormant bluestem range-grass fiber digestibility, whereas moderate (27%) and high (41 %) protein supplementation maintained forage digestibility and encouraged intake. Increased intake for moderate and high protein groups appeared to be associated with increased rumen dry matter and indigestible fiber fill.

Apramycin For The Early-Weaned Pig (1987), Jim L. Nelssen, G L. Allee, R C. Thaler, W H. Turlington Jan 1987

Apramycin For The Early-Weaned Pig (1987), Jim L. Nelssen, G L. Allee, R C. Thaler, W H. Turlington

Kansas Agricultural Experiment Station Research Reports

A total of 108 21-day-old pigs, weighing less than 10 lb, were utilized in two, 28-day trials to compare the effects of feeding high nutrient-density diets with either added apramycin, neomycin, or carbadox on pig performance. In Tria1, pigs fed the diet containing Apralan® gained slightly faster and were more efficient (P<.05) than pigs fed neomycin during the first 14 days postweaning. There were no differences in pig performance in Trials I or II for the entire 28-day period. Two additional 28-day on-farm studies using a total of 427, 21-day old pigs were conducted, feeding a high nutrient-density diet medicated with either apramycin or neomycin plus terramycin. In both on-farm trials, pigs fed apramycin gained faster (P<.05) than pigs fed neomycin plus terramycin for the initial 14 days post weaning. In the second on-farm trial, feed intake was higher (P<.09) during the first 14 days for pigs fed apramycin. Additionally, pigs fed diets medicated with apramycin were slightly heavier (1. 7 and 1.5 additional pounds for the first and second on-farm trials, respectively) at 28 days post weaning compared to pigs fed neomycin plus terramycin. These results indicate that apramycin will improve the performance of early-weaned pigs fed high nutrient-density diets compared to other feed medications.; Swine Day, Manhattan, KS, November 19, 1987

Characteristics Of Preblended Pork During Cooler Storage (1987), Curtis L. Kastner, Y I. Choi, Donald H. Kropf Jan 1987

Characteristics Of Preblended Pork During Cooler Storage (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 bacteria, TBA (measure of fat rancidity), and pH values of preblended pork (preblends). In both HB (hot boned within 2 hr postmortem) and CB (conventionally boned at 24 hr postmortem) preblends, salt increased (P<.05) TBA values (indicates increased rancidity) and decreased (P<.05) growth of psychrotrophic bacteria, whereas phosphate increased (P<.05) pH and decreased TBA values. Salt levels could be reduced from 3.0 to 1.5% in preblends without storage problems, if phosphate (0.5%) was included. Phosphate (mixture pH 7.2) had little influence on microbial growth of preblends during cooler storage.; Swine Day, Manhattan, KS, November 19, 1987
