Utilization Of Near Infrared Reflectancefor The Determination Of Fat, Moisture,And Protein In Cheddar Cheese (1989), G.S. Zink, I.J. Jeon, L.H. Harbers
Kansas Agricultural Experiment Station Research Reports
Near infrared reflectance spectroscopy (NIRS) was used to develop calibration equations for the rapid determination of moisture, protein, and fat in Cheddar cheese. Most mean values from NIRS data had lower standard deviations than values obtained by standard laboratory procedures. A larger number of samples is needed to refine calibrations and validate the equations.; Dairy Day, 1989, Kansas State University, Manhattan, KS, 1989; The 1989 Annual KSU Dairy Day is known as Dairy Day, 1989
Nutritional Considerations For Improved Lean Value (1989), Jim L. Nelssen
Nutritional Considerations For Improved Lean Value (1989), Jim L. Nelssen
Kansas Agricultural Experiment Station Research Reports
The swine industry is in a transitional period as it gears up to produce the lean meat required by the consumer. In fact, pork processors arc increasing the production of lean products (boneless loins, 95% fat-free hams) because consumers are willing to pay premiums for low-fat products. New methods of measuring the amount of lean pork (fat-a-meter, etc.) are being developed rapidly, in order to allow the packer to offer price differentials for lean compared to fat pigs. Pork producers, in my opinion, will adjust production systems to meet consumer demands for lean pork when monetary differentials are offered by …

Effect Of Diet Particle Size On Utilization Of Sunflower Oil Seeds In Nursery Pig Diets (1989), G E. Fitzner, T L. Weeden, Robert H. Hines, Robert D. Goodband
Kansas Agricultural Experiment Station Research Reports
One hundred ninety-two weanling pigs were fed diets containing 15 or 25% sunflower oil seeds that were ground using a hammermill equipped with either a 1/8 or 3/16 in. screen. Average daily gain (ADG) of pigs fed the 25% sunflower seed diet ground through a 1/8 in. screen was similar to ADG of pigs fed the control diet or that with 15% sunflower seeds, although there was a reduction in ADFI. This indicates that finely ground sunflower seeds can be utilized in nursery pig diets up to 25% with no impairment in performance.; Swine Day, Manhattan, KS, November 16, 1989
Fecal Thiaminase In Feedlot Cattle, T.D. Hays, B.E. Brent
Fecal Thiaminase In Feedlot Cattle, T.D. Hays, B.E. Brent
Kansas Agricultural Experiment Station Research Reports
Fecal thiaminase was measured on 152 feedlot cattle at three locations and on a variety of rations. No animals showed signs of polioencephalomalacia. Thiaminase activities ranged from 0.6 to 430 µmol thiamin destroyed per minute per liter of feces (µmol/min/l). Eighty-two percent of the thiaminase activities were below 20 µmol/min/l, and only 3 percent were less than 2 µmol/min/l. High levels of fecal thiaminase were apparently not related to ration. Thiaminase was detected in all animals studied, but one location had only minimal levels. When high levels of thiaminase were found, the samples were re-assayedt and the enzyme was confirmed …

Influence Of Level Of Grain Supplementation On The Performance Of Intensive-Early Stocked Steers, R.C. Cochran, E.S. Vanzant, Clenton E. Owensby
Kansas Agricultural Experiment Station Research Reports
Two levels of sorghum grain supplementation (2 or 4 lb/day) for"¢steers in an intensive-early stocking program tended to increase average daily gain in direct proportion to increasing supplement level (2.7 and 2.9 lb/day. respectively, compared to 2.5 lb with no supplement). Similarly, grass remaining in the pastures after the cattle were removed on July 15, and at the end of the growing season on October 1, was greater when cattle were supplemented.

Effect Of Lasalocid In Rations For Growing Heifers (1989), D.E. Isbell, J.L. Morrill
Kansas Agricultural Experiment Station Research Reports
Sixty-four Holstein heifer calves were used from 10 to 26 wk of age to study the effects of lasalocid on growth and feed consumption. Calves were evaluated weekly for weight gain and feed consumption. Lasalocid-fed heifers gained slightly, but not significantly, more than those that did not receive lasalocid. Their hay consumption was not significantly different than that of the control heifers.; Dairy Day, 1989, Kansas State University, Manhattan, KS, 1989; The 1989 Annual KSU Dairy Day is known as Dairy Day, 1989

Interseeded grain sorghum and soybeans have been evaluated as a silage crop over a 3year period. In the first 2 years, maximum dry matter (DM) yields occurred at the late-dough stage of the grain sorghum, and interseeded silages had higher crude protein (CP) and acid detergent fiber contents than non-interseeded late-dough stage, grain sorghum control silages. In year 2, seeding grain sorghum and soybeans in alternating IS-inch rows increased DM yield, CP content, and the proportion of soybean plants in the mixture compared to drilled (6-inch spacing) interseeding. Digestibilities of most nutrients were similar in all silages; however, cattle fed …
Effects Of Lecithin And Lysolecithin On The Digestibility Of Fat Sources In Diets For Weanling Pigs (1989), D B. Jones, Jim L. Nelssen, Robert H. Hines, Joe D. Hancock
Effects Of Lecithin And Lysolecithin On The Digestibility Of Fat Sources In Diets For Weanling Pigs (1989), D B. Jones, Jim L. Nelssen, Robert H. Hines, Joe D. Hancock
Kansas Agricultural Experiment Station Research Reports
Ninety-six pigs (17 d of age and 11.6 lb initial wt) were utilized to determine if adding emulsifiers (lecithin and lysolecithin) to diets containing 10% added fat would affect nutrient digestibility. Fat sources were: 1) soybean oil, 2) tallow, 3) lard, and 4) coconut oil. Lecithin and lysolecithin were added as 10% of the added fat. Pigs were limit fed using the following equation: daily feed allowance = .05 x body wt^9. After a 7-d adjustment period, feces were collected for 4 d, pooled, and analyzed for fat, nitrogen, and energy content. Soybean oil and coconut oil were more digestible …

Influence Of Milk Levels Of Beef Cows On Returns: A Simulation Approach, R.R. Schalles, K.O. Zoellner, L.S. Clarke
Kansas Agricultural Experiment Station Research Reports
Results of four simulated production systems indicated that high levels of milk produced calves that were heavier at weaning, primarily because of an increase in body fat. High levels of milk production, however, were a disadvantage when calves went directly to the feedlot. With slow-growing calves, the fat either had to be depleted postweaning, or the calves had to be slaughtered at less-than-desirable weights in order to maintain desirable carcass fat. High milk intake is more tolerable for calves with fast growth rates, whereas low milk intake is a an economic necessity for calves with slow growth rates. The moderate …

The swine industry is at a crossroads that either mayor may not change the way we produce pork in the future. As we head into the 90's, we are entering a new era in terms of growth promotion and carcass modification,which will produce overnight what would have taken generations to select for. Of the compounds tested, porcine somatotropin (pST) has the most potential to alter the structure of the swine industry. Many fear the application of this technology because of potential increases in pork production displacing and leading to fewer producers. Because pork quality will be improved tremendously (50% reduction …

Kansas Agricultural Experiment Station Research Reports
We demonstrated that gonadotropin-releasing hormone (GnRH or Cystorelin®) failed to improve pregnancy rates at the first service. When GnRH injection and insemination are both carried out either in early or late estrus or if cows are bred in early estrus and given a GnRH injection later in estrus, pregnancy rates are reduced by 9 to 13 percentage points compared to breeding according to the am-pm rule without GnRH treatment (control). Pregnancy rates of cows injected with GnRH early in estrus and bred in late estrus were similar to controls injected with saline and inseminated late in estrus (46 vs 43%). …

New Concepts In Breeding Barn Design (1989), D G. Levis
Kansas Agricultural Experiment Station Research Reports
Many existing swine breeding facilities have been designed to control the environment, provide continuous boar-sow contact for stimulating recently weaned sows to cycle, reduce the distance a weaned sow or boar has to be moved for mating, and reduce construction costs by not constructing breeding pens to be used only for mating. Pork producers operating these types of facilities have had problems with efficiency and accuracy of estrous detection, low percentage (70%) of sows bred twice, slick breeding floors, and excessive labor requirements. A breeding facility should be arranged so the work routines, such as estrous detection; moving, mating, and …

Feed Utilization During Late Gestation By Polled Hereford And Simmental Cows, R.R. Schalles, G.H. Kiracofe, J.W. Wright
Kansas Agricultural Experiment Station Research Reports
Thirty-one Polled Hereford and 29 Simmental cows were individually fed two energy levels for about the last 4 months before calving. Weight, condition score, backfat thickness, and reproduction were evaluated. No differences were found in efficiency of feed utilization between breeds or between energy levels. These cows started the experiment in moderate body condition, and a 10% reduction in dietary energy level during late gestation did not affect their reproductive performance.

Effect Of Foraform® On Fermentation Of Alfalfa, Corn, And Forage Sorghum Silages, K.K. Bolsen, A. Laytimi, A.D. Drysdale
Kansas Agricultural Experiment Station Research Reports
Foraform® was evaluated in four trials using alfalfa, corn, and two forage sorghums harvested in 1987 and ensiled in PVC laboratory silos. There was a dramatic crop by Foraform interaction, with Foraform delaying and restricting the fermentations, as expected, in alfalfa and corn. In both forage sorghum hybrids, although the ensiling process was delayed about 24 hours by the Foraform treatment, end-product silages had lower pH values and equal or higher lactic acid levels than untreated silages. Foraform was effective at both 60 to 90 F temperatures in alfalfa, with treated silages having lower lactic and acetic acids, ethanol, and …

Dietary Influences On Pancreatic Amylase And Small Intestinal Disaccharidase Activities In Cattle, K.K. Kreikemeier, D.L. Harmon, K. Gross, C. Armendariz
Kansas Agricultural Experiment Station Research Reports
Pancreatic α-amylase activity was 54% higher in cattle fed at twice maintenance energy than in cattle fed at maintenance and was 52% greater in hay-fed than grain-fed cattle. Increased pancreatic α-amylase activity probably represents increased secretion as well. α-amylase activity in small intestinal digesta was greater with increased energy intake and with hay feeding. Small intestine mucosal disaccharidase activities in cattle were unaffected by diet. Lactase activity was highest in the proximal segment of the small intestine and low in both mid and distal segments. Maltase and isomaltase activities were low in the duodenum, but increased toward the jejunum and …

The types and diameters of muscle fibers from 30 barrows that had received daily injections of porcine somatotropin (pST) or a placebo and were fed dietary lysine at .6, .8, 1.0 or 1.2% were determined. Fiber data indicated that pST slightly increases the anaerobic metabolic potential of longissimus muscle. The higher levels of lysine caused enlargement of muscle cells. Earlier research has shown that this type of muscle biochemistry contributes to development of PSE muscle. Thus, use of pST in certain strains of pigs may lead to reductions in muscle quality.; Swine Day, Manhattan, KS, November 16, 1989

All other amino acids, vitamins, and minerals were calculated to be at least double the pig's requirement (NRC, 1988), to ensure that no nutrient other than lysine would limit performance. When the pen mean weight reached approximately 235 lb, six pigs per treatment were slaughtered, and …

Kansas Agricultural Experiment Station Research Reports
Odd-numbered pigs in new-born litters were vaccinated on d 1 with an oral Escherichia coli bacterin and their performance after weaning was compared with that of nonvaccinated littermates (even numbered pigs). In addition, each group of pigs was allotted to four water medication treatments that were administered from d 2 to d 6 after weaning. No significant interaction between vaccine and water treatment was observed. Vaccinated and non-vaccinated pigs performed similarly throughout the trial for the traits of ADG, ADFI, and F/G, indicating no beneficial effect from vaccination. Water medication after weaning did not affect performance or incidence of scours …
