Effects Of Enzyme Supplementation And Particle Size Of Wheat-Based Diets On Nursery And Finishing Pigs (1998), I Mavromichalis, G A. Kennedy, Robert H. Hines, B W. Senne, S P. Sorrell, Joe D. Hancock, Joel M. Derouchey Jan 1998

Effects Of Enzyme Supplementation And Particle Size Of Wheat-Based Diets On Nursery And Finishing Pigs (1998), I Mavromichalis, G A. Kennedy, Robert H. Hines, B W. Senne, S P. Sorrell, Joe D. Hancock, Joel M. Derouchey

Kansas Agricultural Experiment Station Research Reports

In nursery pigs, enzyme supplementation generally had no effect on ADG or F/G, but a trend occurred for greater digestibility of DM in pigs fed enzymes. However, one notable interaction occurred. Enzyme supplementation gave improved F/G at the coarser (l,300 mm) particle size but not at the finer (600 or 400 mm) particle sizes. In finishing pigs, trends for better F/G and digestibilities of DM and N with enzyme supplementation occurred in one experiment (1,300 vs 600 mm) but not in the other experiment (600 vs 400). Thus, the effects of enzyme supplementation were neither large nor consistent, but wheat …

Effects Of Poultry Fat And Choice White Grease On Pork Longissimus Muscle, Belly, And Bacon Quality (1998), J J. Engel, J W. Smith Ii, Robert D. Goodband, John A. Unruh, Michael D. Tokach, Jim L. Nelssen Jan 1998

Effects Of Poultry Fat And Choice White Grease On Pork Longissimus Muscle, Belly, And Bacon Quality (1998), J J. Engel, J W. Smith Ii, Robert D. Goodband, John A. Unruh, Michael D. Tokach, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

Eighty-four crossbred gilts were used to examine the effects of increasing dietary additions of poultry fat (PF) or choice white grease (CWG) on longissimus muscle (LM), belly, and bacon quality. Pigs fed PF had greater LM cooking loss values than those fed CWG. As PF increased in the diet, LM Minolta L* and belly lean values decreased. then increased. Neither fat source nor level significantly affected other LM quality or sensory traits. As PF increased, bacon slicing score decreased. Although all taste panel scores were well within acceptable ranges, bacon from pigs fed PF had higher sensory panel "off flavor" …

Kansas Agricultural Experiment Station Research Reports

Overall ADG and ADFI were not affected, but feed efficiency was improved with pelleting and further improvements resulted from expander processing. In a second experiment, enzyme supplementation to mash, but not pelleted, diets improved feed efficiency. Indeed, F/G for pigs fed mash with enzyme was similar to that for pigs fed pelleted diets.; Swine Day, Manhattan, KS, November 19, 1998

Kansas Agricultural Experiment Station Research Reports

In nursery pigs, the greatest digestibilities of DM, N, and OE were observed with soft sorghum. In finishing pigs, no difference was observed in digestibility of nutrients among the sorghum genotypes. Chicks fed soft sorghum had better F/G than chicks fed medium and hard sorghum. Finally, thermal processing (steam flaking and extrusion) improved ADG and F/G and digestibilities of DM, N, and GE compared to grinding (coarse and fine).; Swine Day, Manhattan, KS, November 19, 1998

Influence Of Chop Location On Boneless Pork Loin Quality (1998), A T. Waylan, R C. Johnson, John A. Unruh Jan 1998

Influence Of Chop Location On Boneless Pork Loin Quality (1998), A T. Waylan, R C. Johnson, John A. Unruh

Kansas Agricultural Experiment Station Research Reports

Eighty-two boneless pork loins were used to examine the effects of chop location on longissimus muscle quality. The highest quality chops came from the posterior end. They had the lowest Warner-Bratzler shear value (most tender), highest cooking yield, and a high pH and percent extractable lipid. Visual and instrumental data suggested that the most posterior chop was lighter colored and had the highest degree of marbling. Color, firmness, and marbling evaluations were similar in the central posterior section of the loin. This suggests that this section was very uniform in visual pork quality. The anterior portion of the loin was …

Expander Processing Conditions Affect Nutrient Digestibility In Finishing Pigs Fed Corn-, Sorghum-, Wheat-, And Wheat Midds-Based Diets (1998), S L. Traylor, Robert H. Hines, D J. Lee, S L. Johnston, P Sorrell, Joe D. Hancock, Keith C. Behnke Jan 1998

Expander Processing Conditions Affect Nutrient Digestibility In Finishing Pigs Fed Corn-, Sorghum-, Wheat-, And Wheat Midds-Based Diets (1998), S L. Traylor, Robert H. Hines, D J. Lee, S L. Johnston, P Sorrell, Joe D. Hancock, Keith C. Behnke

Kansas Agricultural Experiment Station Research Reports

Expander processing of corn-, sorghum-, wheat-, and wheat midds-based diets improved nutrient digestibility in growing pigs and, thus, the apparent digestible energy concentration in the diets. This new feed manufacturing technology was especially beneficial to the feedstuff with the highest fiber content (i.e., wheat midds).; Swine Day, Manhattan, KS, November 19, 1998

Influence Of Duration Of Dietary Vitamin E Supplementation On Fresh And Cured Pork Color Stability (1998), J F. Stika, John A. Unruh, Donald H. Kropf, Melvin C. Hunt, Robert D. Goodband Jan 1998

Influence Of Duration Of Dietary Vitamin E Supplementation On Fresh And Cured Pork Color Stability (1998), J F. Stika, John A. Unruh, Donald H. Kropf, Melvin C. Hunt, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

Supplementing finishing pigs genetically predisposed to lipid deposition with atocopheryl acetate above 12 IU/lb of feed for as long as 70 d did not improve color stability of fresh and cured pork. Tissue a-tocopherol levels were similar across dietary treatments and higher than predicted. Muscle accumulation of a-tocopherol may be related to the rate and extent of lipid deposition in muscle. Also, chill temperature and carcass chill rate variability, under spray chill conditions, did not influence fresh pork color stability when carcasses with excessive amounts of external fat were utilized.; Swine Day, Manhattan, KS, November 19, 1998

Influence Of Duration Of Dietary Vitamin E Supplementation On Swine Growth Performance And Carcass Quality (1998), J F. Stika, John A. Unruh, Donald H. Kropf, Melvin C. Hunt, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

Supplementing medium-lean genotype pigs with supranutritional concentrations of dietary vitamin E (91 IU d-a-tocopheryl acetate/lb of feed) for as long as 70 d during the finishing phase was not effective in improving swine performance, feeding characteristics, and 24 h loin muscle quality. However, lower carcass temperatures obtained by spray chilling pork sides at O°C versus 4.4°C had a beneficial effect on 24 h carcass quality by improving marbling and lean firmness scores and reducing loin muscle moisture exudate. Overall, 24 h pork carcass quality was impacted more by chill rate than dietary vitamin E supplementation.; Swine Day, Manhattan, KS, November …

Effect Of Date Of Harvest On The Nutritional Quality Of Native Grass Hay (1998), J.C. Baker, S.R. Tonn, David E. Kehler, Dale A. Blasi Jan 1998

Effect Of Date Of Harvest On The Nutritional Quality Of Native Grass Hay (1998), J.C. Baker, S.R. Tonn, David E. Kehler, Dale A. Blasi

Kansas Agricultural Experiment Station Research Reports

Native grass hay meadows in three Kansas Flint Hills counties were sampled at 2-week intervals during the growing season to determine the effect of harvest date on forage quality. Each sample was analyzed for crude protein (CP), acid detergent fiber (ADF), and phosphorus (PHOS). CP and PHOS contents declined, and ADF increased as harvest date progressed into the growing season. Both CP and ADF were related highly to harvest date. PHOS content was associated only moderately with harvest date. Harvest date of native grass hay can significantly influence supplemental protein needs for beef cows.

Effects Of Processing Whole-Plant Corn Silage On Growth Performance And Nutrient Digestibility In Feedlot Cattle (1998), T.J. Wistuba, M.K. Siefers, J.E. Turner, G.L. Huck, K.K. Bolsen, Matthew A. Young, Ronald V. Pope

Kansas Agricultural Experiment Station Research Reports

Sixty crossbred heifers and 12 crossbred steers were used to evaluate the effects of mechanically processing (crushing the kernels of) whole-plant corn silage on feedlot performance and nutrient digestibility. The three treatments were: preensiled processed, postensiled processed, and nonprocessed corn silages. Heifers fed the processed corn silages grew faster and were more efficient than those fed nonprocessed silage. Steers consuming the two processed silage rations had numerically higher DM, OM, NDF, and ADF digestibilities and significantly higher starch digestibilities than those fed the non- processed silage ration. These data suggest that processing whole-plant corn silage before or after ensiling has …

Effects Of Various Carbohydrate Sources On The Utilization Of Low-Quality Tallgrass-Prairie Hay In Continuous Culture, J.S. Heldt, R.C. Cochran, C.P. Mathis, Evan C. Titgemeyer, Tiruvoor G. Nagaraja Jan 1998

Effects Of Various Carbohydrate Sources On The Utilization Of Low-Quality Tallgrass-Prairie Hay In Continuous Culture, J.S. Heldt, R.C. Cochran, C.P. Mathis, Evan C. Titgemeyer, Tiruvoor G. Nagaraja

Kansas Agricultural Experiment Station Research Reports

We evaluated the effects of supplemental carbohydrate sources on the utilization of low- quality forage in continuous "artificial rumen" culture. Providing readily digestible carbohydrates (starch, glucose, and fiber) did not improve total diet digestion. In fact, starch and glucose depressed fiber digestion. Response to other simple sugars was variable.

Fusobacterium Necrophorum In Ruminal Contents And On The Ruminal Wall Of Cattle (1998), K.R. Bedwell, N. Wallace, Tiruvoor G. Nagaraja

Kansas Agricultural Experiment Station Research Reports

Fusobacterium necrophorum was quantified from ruminal contents and ruminal wall tissue collected at slaughter. Livers were examined and scored for abscesses. The mean concentration of F. necrophorum on the ruminal wall ranged from 2.9 x 103 to 6.1x 105 per cm2 . The dorsal sac had the lowest counts, and dorsal blind and ventral sacs had the highest counts of F. necrophorum adherent to the ruminal wall. The concentrations of F. necrophorum in ruminal contents and on the ruminal wall did not appear to be related to presence or absence of abscessed livers or to severity of abscesses.

Wheat Middlings In Roughage-Based Or Limit-Fed, High-Concentrate Diets For Growing Calves (1998), Gerry L. Kuhl, R.H. Wessels, Dale A. Blasi, James S. Drouillard Jan 1998

Wheat Middlings In Roughage-Based Or Limit-Fed, High-Concentrate Diets For Growing Calves (1998), Gerry L. Kuhl, R.H. Wessels, Dale A. Blasi, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

A 101-day growing study was conducted to evaluate the growth performance of beef heifers fed wheat middlings in traditional full- fed, sorghum silage-based rations and in limit-fed, high-concentrate rations. Diets were formulated without wheat middlings or with wheat middlings replacing 33, 67, or 100% of rolled corn plus soybean meal. Daily gains decreased linearly (P<.01) with increasing levels of wheat middlings in the roughage-based diets because of lower feed intake (P<.10), but feed efficiency was not affected (P>.30). For the limit-fed diets, heifer daily gains decreased linearly (P<.01) as the proportion of wheat middlings in the diet increased, resulting in a linear reduction (P<.01) in feed efficiency. Wheat middlings can be utilized effectively as the predominant energy/protein source for growing cattle, though their nutritional and economic value, relative to corn and soybean meal, may be different for roughage-based and limit-fed diets.

Development Of An In Vitro Procedure To Determine Ruminal Availability Of Protein (1998), C.K. Schoenholz, James S. Drouillard, C.K. Armendariz, Evan C. Titgemeyer Jan 1998

Development Of An In Vitro Procedure To Determine Ruminal Availability Of Protein (1998), C.K. Schoenholz, James S. Drouillard, C.K. Armendariz, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

A series of in vitro experiments was conducted to determine the ruminal availability of protein from grains. Procedures were based on assumptions that 1) ruminal availability of protein is first-limiting to microbial growth, 2) accumulation of microbial cells accurately predicts ruminal protein availability,3) cytosine can be used to accurately estimate microbial cell mass, and 4) cytosine is present in microorganisms but not in feeds. Cytosine content of in vitro cultures was measured by high performance liquid chromatography. Early experiments determined that adding 0.75 g soluble starch provided enough energy that culture growth depended on available protein. In the final experiment, …

Kansas Agricultural Experiment Station Research Reports

DNA finger printing (restriction fragment length polymorphism analysis) was employed to genetically compare Fusobacterium necrophorum isolates of liver abscesses, ruminal wall, and ruminal contents from the same animal. Fusobacterium necrophorum isolates from liver abscesses were genetically identical to the corresponding isolates from the ruminal wall in eight of nine animals tested. This genetic similarity between the isolates supports the hypothesis that F. necrophorum in liver abscesses originates from the ruminal wall.
