Supplementation Of Ammoniated Wheat Straw In Wintering Diets Of Gestating Beef Cows, T.J. Beck, D.D. Simms, Robert T. Brandt Jr., R.C. Cochran, Gerry L. Kuhl Jan 1991

Supplementation Of Ammoniated Wheat Straw In Wintering Diets Of Gestating Beef Cows, T.J. Beck, D.D. Simms, Robert T. Brandt Jr., R.C. Cochran, Gerry L. Kuhl

Kansas Agricultural Experiment Station Research Reports

During two winters, 96 beef cows in late gestation were utilized in 60-day precalving feeding trials to evaluate supplementation for cows fed ammoniated wheat straw. Treatments included: control--mineral supplement only (C), 3 lbs milo + mineral (3M), 6 lb milo + mineral (6M), and 2.75 lb milo + .75 lb soybean meal + mineral (SBM). 3M increased (P<.05) cow gain over control but body condition changes were similar. 6M and SBM resulted in similar gains and body weight changes, which were higher than those of cows receiving either C or 3M. Birth weight of calves, percent cycling at the start of breeding, and percent pregnant after a 60-day breeding season were not affected by treatment. Natural protein appears to be a major limiting nutrient in cows fed ammoniated wheat straw.

Predicting Nutritional Composition Of Corn Grain Using Near Infrared Reflectance Spectroscopy, G. Garcia-Lagombra, L.H. Harbers Jan 1991

Predicting Nutritional Composition Of Corn Grain Using Near Infrared Reflectance Spectroscopy, G. Garcia-Lagombra, L.H. Harbers

Kansas Agricultural Experiment Station Research Reports

Corn grain samples collected over several years were used to develop equations for dry matter, crude protein, crude fiber, and ether extract (crude fat). Two computer models were used to select samples having a range of spectra (presumably a range of nutrient values) for developing calibration equations. Both methods selected an unexpectedly small number of samples; however, only the prediction of crude fiber appears questionable. Although coefficients of determination values are expected to be low with a small number of samples, standard errors of validation and prediction are consistently lower than those of standard (AOAC) methods, suggesting that the technology …

Release Of Parasitic Wasps To Control Stable Flies In Kansas Dairies (1991), G. L. Greene

Kansas Agricultural Experiment Station Research Reports

After release of fly parasites in Kansas dairies during 1991, parasitism increased from May to late June then dropped in July. The parasite released was Spalangea nigroaenea of Kansas origin to assure its adaption to Kansas conditions. Additional studies of fly parasite releases are needed to develop a reliable fly reduction program for Kansas dairies before fly parasite purchases can be reliably recommended. Release of adapted parasite species and removal of fly breeding areas will be essential for reduction of fly numbers at Kansas dairies.; Dairy Day, 1991, Kansas State University, Manhattan, KS, 1991;

Pigs were fed a milo-soybean meal diet balanced on a constant energy:lysine and energy:protein ratio. Dietary treatments were: 1) control; 2,3,4) 2.5, 5.0, or 7.5% added soybean oil; 5 and 6) 5.0 or 7.5% added tallow. In comparing pigs fed soybean oil to tallow, there were no significant effects on feed intake, average daily gain, or feed to gain ratio. Soybean oil additions compared to tallow resulted in carcasses with significantly more average backfat as well …

Near-infrared reflectance spectroscopy (NIRS) offers the potential for rapid, low-cost analyses of meat samples. Beef and pork samples were analyzed by both standard laboratory (AOAC) methods and NIRS. Regression equations were developed to relate the two methods. Coefficients of determination between NIRS and AOAC results were .929 for dry matter, .965 for crude protein, and .996 for ether extract. NIRS and AOAC procedures yielded very similar results (DM, 38.82 vs 38.58; CP, 17.78 vs. 17.83; and EE, 18.83 vs. 18.00). NIRS appears to be a rapid and reliable predictor of nutritional composition of ground beef and pork based on regression …
