High Moisture Tempering Of Corn Before Flaking: Effects On Bacterial Contamination From Houseflies And Fecal Shedding In Finishing Cattle (2003), A.B. Broce, C.M. Gordon, J.J. Sindt, Brandon E. Depenbusch, James S. Drouillard, Randall K. Phebus

Kansas Agricultural Experiment Station Research Reports

Tempered and non-tempered steam-flaked corn samples along with total mixed rations containing either tempered or non-tempered steam-flaked corn were exposed to flies and the environment for 21 hours. Exposure to flies and the environment increased (P0.05) alter microbial counts of total mixed rations regardless of tempering (Table 1). Generic E. coli coliforms were greater in total mixed rations when the corn was tempered, both before and after exposure to flies and the environment (P0.05), but acid-resistant (pH 2) non-E. coli and total fecal coliforms (Table 2) were lower in feces of cattle fed the tempered grain than those fed non-tempered …

Comparison Of Concentrated Separator Byproduct And Cane Molasses For Finishing Heifers (2003), E.R. Loe, T.J. Kessen, Sean P. Montgomery, J.N. Pike, J.J. Sindt, M.J. Sulpizio, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

We compared concentrated separator byproduct (CSB) to cane molasses on feedlot performance and carcass merit of 394 crossbred yearling beef heifers fed for 148 days. Sugar beet molasses undergoes a process in which approximately half of the sugar is removed, concentrating protein and mineral in CSB. Compared with cane molasses, CSB has more crude protein, ash, and moisture. Two diets based on steam-flaked corn containing either CSB or cane molasses at 5% (dry matter basis) of the diet were fed. Feedlot performance was similar between heifers fed the two diets (P>0.23). Apparent dietary concentrations of net energy for gain …

Effect Of Feeding Conventional Or High-Moisture, Steam-Flaked Corn To Finishing Heifers (2003), J.J. Sindt, T.J. Kessen, M.J. Sulpizio, E.R. Loe, Sean P. Montgomery, James S. Drouillard Jan 2003

Effect Of Feeding Conventional Or High-Moisture, Steam-Flaked Corn To Finishing Heifers (2003), J.J. Sindt, T.J. Kessen, M.J. Sulpizio, E.R. Loe, Sean P. Montgomery, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Finishing heifers were fed diets containing either conventional (18% moisture) or high-moisture (36% moisture) steam-flaked corn. Increasing moisture concentration in flakes increased starch availability (P<0.01), but feeding heifers high-moisture flakes decreased (P<0.05) dry matter intake and average daily gain compared to heifers fed conventional flakes. Feeding heifers high-moisture flakes also numerically reduced hot carcass weight and ribeye area, but caused (P<0.01) heifers to deposit more fat over their 12th rib. Extreme levels of moisture in flaked corn improve starch availability but do not appear to increase heifer performance or carcass value. The interaction between moisture and flake density needs further evaluation.

Kansas Agricultural Experiment Station Research Reports

A large increase in the number of ethanol plants has lead to increased availability of dried distiller's grains with solubles (DDGS). New plants also have improved processing techniques, which makes DDGS more attractive to use in swine diets. Two experiments were conducted to determine the energy value of DDGS. In Experiment 1, 360 pigs (each initially 38.5 lb) were used in a 22 d growth assay. Treatments consisted of five corn-soybean meal-based diets with added wheat bran or soy oil to provide five different energy densities ranging from 1,390 to 1,604 Kcal/lb ME.

Pelleted Diets For Lactating Sows (2003), E C. Baudon, Joe D. Hancock Jan 2003

Pelleted Diets For Lactating Sows (2003), E C. Baudon, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

A total of 76 sows (parities one to four) were used to determine the effects of pelleted diets on sow and litter performance. In the 21-d lactation experiment, the sows were given a corn-soybean meal-based diet in meal (corn ground to a particle size of 500 to 600 μm) or a pelleted (3/16 inch pellet diameter) form. Diet form did not affect ADFI or lactation BW loss (P=0.15 or greater). Also, pigs weaned per litter, piglet survivability, litter weight gain, and days to estrus were not affected by treatment (P=0.15 or greater). However, sows fed pelleted feed lost less backfat …

Particle Size Of Corn In Lactation Diets For Mixed-Parity Sows (2003), E C. Baudon, Joe D. Hancock, Michael D. Tokach Jan 2003

Particle Size Of Corn In Lactation Diets For Mixed-Parity Sows (2003), E C. Baudon, Joe D. Hancock, Michael D. Tokach

Kansas Agricultural Experiment Station Research Reports

A total of 107 mixed-parity sows (parities one to four) was used to determine the effects of particle size of corn in lactation diets on sow and litter performance. The sows were fed corn-soybean meal-based diets with targeted corn particle sizes of 1,500, 900, and 600 μm (actual means particle sizes of corn during the experiment were 1,600, 824 and 619 μm). Reducing mean particle size of the corn in lactation diets from 1,500 to 600 microns resulted in greater ADFI and water usage (linear effects, P<0.02), fewer days for return to estrus after weaning (linear effect, P<0.04), and less backfat loss (quadratic effect, P<0.03) for the sows. Although the trends in pigs weaned per litter, piglet survivability, litter weaning weight, and litter weight gain were in the same direction as those for feed intake and water usage in the sows, the difference in measurements of litter performance was not statistically important among treatments (P = 0.15 or greater). Intakes of DM, N, and GE by the sows were increased by 9, 4, and 7% and apparent digestibilities of DM, N, and GE were increased by 6, 5, and 7%, respectively, as particle size of corn was decreased from 1,500 to 600 μm (linear effects, P<0.001). Finally, excretion of DM and N in the feces was decreased (linear effect, P<0.002) by 178 g/d and 5 g/d, respectively, as particle size of the corn on the sow diets was reduced. In conclusion, reducing particle size of corn did not affect litter performance but increased feed intake and digestibility of nutrients and reduced nutrient excretion in sows.; Swine Day, 2003, Kansas State University, Manhattan, KS, 2003

Kansas Agricultural Experiment Station Research Reports

A 32-day growth study with a total of 252 weanling pigs (18 ± 3 d of age) was conducted to evaluate the effects of a prebiotic, Inulin (a fructooligosaccharide derivative of chicory), and a direct fed microbial (Lactobacillus strain) in diets for weanling pigs. Pigs were fed one of six experimental diets containing: 1) no antibiotic or prebiotic (negative control); 2) carbadox (50 g/ton, positive control); 3) direct fed microbial (DFM, 0.1%); 4) Inulin (0.5% and 0.2% of phase I and phase II diets, respectively); 5) carbadox plus DFM; or 6) carbadox plus Inulin. Pigs fed carbadox improved (P<0.04) ADG from d 0 to 14, 14 to 32, and overall (0 to 32) compared to pigs fed diets without carbadox. Pigs fed diets containing carbadox increased (P<0.01) ADFI from d 0 to 14 and tended to have increased (P<0.06) ADFI overall compared to pigs fed diets without carbadox. No differences in ADG or ADFI were seen for pigs fed diets containing either Inulin or the DFM compared to pigs fed diets without Inulin or DFM. Pigs fed the DFM had poorer feed efficiency d 0 to 14 (P<0.03), 14 to 32 (P<0.01), and overall (P<0.01) compared to those fed diets without DFM. Also, there was a trend for pigs fed diets containing Inulin to have poorer feed efficiency (P<0.07) from d 14 to 32 and overall when compared to pigs fed diets without Inulin. There were no additive responses for ADG or ADFI when Inulin or DFM were combined with carbadox. Pigs fed diets containing both the DFM and carbadox resulted in poorer feed efficiency (P<0.02) from d 14 to 32 and overall (0 to 32) than pigs fed diets without carbadox or DFM. Pigs fed the diet containing Inulin and carbadox had poorer feed efficiency from d 0 to 14 (P<0.04) compared to pigs fed diets without carbadox or Inulin. In summary, nursery diets containing either Inulin or the DFM did not enhance growth performance; however, carbadox improved ADG and ADFI.; Swine Day, 2003, Kansas State University, Manhattan, KS, 2003

Kansas Agricultural Experiment Station Research Reports

A total of 144 finishing pigs (72 barrows and 72 gilts, initially 85 lb) were used to determine the effects of calcium to total phosphorus (Ca:P) ratio in diets containing phytase on growth performance, carcass characteristics, and bone ash percentage. Pigs were housed in an environmentally regulated finishing building with two pigs per pen and six pens per sex per treatment in a randomized complete block design. Pigs were blocked by initial weight and sex, and then allotted to one of six dietary treatments. The dietary treatments were corn-soybean meal-based diets fed in three phases. In each phase, diets consisted …

Effect Of Added Fat On Performance Of Growing-Finishing Pigs In Commercial Conditions (2003), M G. Young, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz Jan 2003

Effect Of Added Fat On Performance Of Growing-Finishing Pigs In Commercial Conditions (2003), M G. Young, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of 1,040 pigs (half barrows and half gilts) was used in a 42-day experiment conducted in a commercial research facility to determine the influence of graded levels of added fat on growth performance, feed cost per pound of gain and margin over feed of growing-finishing pigs. The four dietary treatments were based on level of added dietary fat (0, 2, 4, or 6%), with the diets fed for a six-week period from 158 to 232 lb. Adding fat to the diet for pigs weighing 158 to 232 lb decreased ADFI, improved feed efficiency, increased cost per pound of …

Comparison Of Antimicrobial Alternatives In Irradiated Diets For Nursery Pigs (2003), T P. Keegan, C W. Hasted, Joel M. Derouchey, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband, Steven S. Dritz Jan 2003

Comparison Of Antimicrobial Alternatives In Irradiated Diets For Nursery Pigs (2003), T P. Keegan, C W. Hasted, Joel M. Derouchey, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Previous research at Kansas State University indicated that irradiation can effectively reduce the bacteria concentration in nursery diets. Therefore, we hypothesized that eliminating bacteria in the feed via irradiation would provide a model to determine the effectiveness of antimicrobial alternatives. In a 27-d growth assay, 330 weanling pigs (13.2 lb and 18 ± 2 d of age, PIC) were fed one of 9 experimental diets: 1) control diet with no antimicrobials, 2) irradiated control diet with no antimicrobials, and the irradiated control diet with added: 3) carbadox (50 g/ton), 4) Probios® (1.6% from d 0 to 14 and 0.8% from …

Kansas Agricultural Experiment Station Research Reports

A total of 320 weanling pigs (10.7 lb and 14 ± 3 d of age, PIC) was used to determine the effects of antibiotics and an antibiotic alternative on nursery pig performance. Pigs were fed one of 5 experimental diets: 1) control with no antimicrobials; 2) carbadox (50 g/ton); 3) Denagard/CTC (35 g/ton Denagardâ„¢, 400 g/ton Chlortetracycline); 4) Neo-Terramycin® (140 g/ton Neomycin Sulfate, 140 g/ton Oxytetracycline HCl); 5) Bio Mos (0.3%, mannanoligosaccharide). Overall (d 0 to 31 post-weaning), pigs fed the diet containing Denagard/CTC had the greatest (P<0.05) ADG and ADFI compared to pigs fed all other treatment diets. Pigs fed the diet containing Neo-Terramycin had greater (P<0.05) ADG compared to pigs fed the control diet or diets containing Carbadox or Bio Mos. In addition, pigs fed the diet containing Neo-Terramycin had greater (P<0.05) ADFI compared to pigs fed the control diet or the diet containing Bio Mos. In conclusion, the addition of carbadox and Bio Mos did not result in improved growth performance compared to pigs fed the control diet. However, improvements were seen in average daily gain and daily feed intake with the addition of Denagard/CTC and Neo-Terramycin. Commercial operations need to determine which feed additives improve nursery pig performance in their individual production systems.; Swine Day, 2003, Kansas State University, Manhattan, KS, 2003

Estimating The Impact Of Animal Health And Death Loss On Economic Performance Of Feedlot Cattle (2003), M. Irsik, Michael R. Langemeier Jan 2003

Estimating The Impact Of Animal Health And Death Loss On Economic Performance Of Feedlot Cattle (2003), M. Irsik, Michael R. Langemeier

Kansas Agricultural Experiment Station Research Reports

This study examined the impacts of animal health and death loss on the economic performance of feedlot cattle. Using data from two feedlots in western Kansas, the impact of animal health on economic performance was quantified. Death loss and the percentage of animals treated significantly impacted feed conversion, average daily gain, and cost of gain. Feed conversion for a pen of cattle was found to increase by 0.27 lb feed/lb gain and daily gain decreased by 0.08 lb/day for each percentage point increase in death loss. An increase in death loss from 1% to 2% increased cost of gain by …

Kansas Agricultural Experiment Station Research Reports

The infraspinatus muscle (top blade) from the chuck clod, the gluteus medius muscle (top sirloin) from the sirloin, and the psoas major muscle (tenderloin) from the loin were obtained from 140 A- and B-maturity carcasses with either low-Slight or Small marbling and with either normal pH (5.7 or less) or high ultimate pH (6.0 or higher) to evaluate factors that could cause livery flavor in cooked beef. Muscles were aged for 7, 14, 21, or 35 days. A highly trained, flavor-profile sensory panel evaluated charbroiled steaks from these muscles. Approximately 8% of all sensory panelist judgments were scored to have …
