Kansas Agricultural Experiment Station Research Reports

Lactic acid sprays effectively reduce the microbial load on both carcasses and subprimal cuts. Lactic acid decontamination of subprimals appears to carry through to retail cuts during display. Because of recontamination during fabrication, treating subprimals may be more effective than treating carcasses. This information will allow us to identify the most critical control points at which to employ decontamination practices designed to reduce the incidence of pathogenic bacteria and extend shelf life.

Effect Of Lactic Acid Sprays On Shelf Life And Microbiological Safety Of Beef Subprimals, R.K. Prasai, L.E. Mease, L.R. Vogt, Donald H. Kropf, Daniel Y.C. Fung, Curtis L. Kastner Jan 1994

Effect Of Lactic Acid Sprays On Shelf Life And Microbiological Safety Of Beef Subprimals, R.K. Prasai, L.E. Mease, L.R. Vogt, Donald H. Kropf, Daniel Y.C. Fung, Curtis L. Kastner

Kansas Agricultural Experiment Station Research Reports

Beef loins were sprayed with 1.5% lactic acid either before or after vacuum storage, both before and after vacuum storage, and before vacuum packaging followed by a water spray after storage. We stored treated loins at either 30EF or 36EF for up to 126 days in vacuum packages. Nonsprayed or nonstored loins served as controls. Total aerobic plate counts (APCs) and tests for presence/absence of two important foodborne pathogens, Salmonella spp. and Listeria monocytogenes, were conducted during storage. Acid spraying prior to vacuum packaging was more effective in reducing bacterial contamination than spraying after storage. However, counts were reduced (P<.05) for only 28 days of storage. Most loins stored at 30EF had lower APCs than those stored at 36EF. Salmonella was not detected in any samples. Twenty-eight percent of nonacid treated and 4 percent of acid-treated loins were positive for Listeria spp. with L. monocytogenes found from one nonacid-treated loin. No change in visual color was observed in acid-treated loins. Appropriate timing of acid s praying in combination with lower storage temperature can improve the keeping quality and microbial safety of meat.

Use Of Oxyrase® Enzyme To Enhance Recovery Of Escherichia Coli O157:H7 From Culture Media And Ground Beef, H. Thippareddi, K. Kone, Randall K. Phebus, Daniel Y.C. Fung, Curtis L. Kastner

Kansas Agricultural Experiment Station Research Reports

Escherichia coli O157:H7 is a bacterium that has caused great concern in the meat and food industry during the last few years because of several, well-publicized, disease outbreaks, including the incident at the Jackin- the-Box fast food chain in Seattle, Washington. The organism can cause severe sickness and even death in certain population groups. To better assure meat safety, federal meat inspection is focusing on developing rapid methods to detect this disease agent and others. Oxyrase is a commercially available enzyme that can accelerate the growth of some bacteria. Current techniques for isolation and culturing of E. coli O157:H7 from …

Estimates Of Genetic And Phenotypic Parameters For Carcass And Meat Traits Of Beef Cattle, K.E. Gregory, L.V. Cundiff, R.M. Koch, M. Koohmaraie, Michael E. Dikeman Jan 1994

Estimates Of Genetic And Phenotypic Parameters For Carcass And Meat Traits Of Beef Cattle, K.E. Gregory, L.V. Cundiff, R.M. Koch, M. Koohmaraie, Michael E. Dikeman

Kansas Agricultural Experiment Station Research Reports

Data from nine parental breeds and three composite populations described in the preceding article were used to calculate heritabilities and phenotypic and genotypic correlations among carcass and meat traits. Phenotypic correlations indicated that marbling was a poor predictor of longissimus muscle palatability attributes of the individual carcasses. Heritability estimates were intermediate to high for fatness measures but generally low for palatability attributes. The high negative genetic correlation (-.56) between percentage of retail product and marbling score and the relatively low genetic correlations between percentage of retail product and palatability attributes suggest simultaneous selection for percentage of retail product and palatability, …

Stage Of Lactation Profile Reflects Nutrition And Management (1994), James R. Dunham Jan 1994

Stage Of Lactation Profile Reflects Nutrition And Management (1994), James R. Dunham

Kansas Agricultural Experiment Station Research Reports

The Stage of Lactation Profile (SOLP) is a good estimate of the shape of the lactation curve for dairy herds. The SOLPs for herds with various milk production levels are somewhat similar. The rates of decline of all SOLPs are about the same. Therefore, the differences in production levels are about the same in late stages of lactation and in early lactation, regardless of production Rolling Herd Average (RHA). In addition, higherproducing herds have their highest level of production in the second stage of lactation (51 to 100 days in milk), whereas this occurs in the first stage of lactation …

Ruminal Degradation Of Dietary Protein In Steers Fed Lasalocid (1994), R.H. Wessels, Evan C. Titgemeyer, Jean G. St. Jan 1994

Ruminal Degradation Of Dietary Protein In Steers Fed Lasalocid (1994), R.H. Wessels, Evan C. Titgemeyer, Jean G. St.

Kansas Agricultural Experiment Station Research Reports

A trial was conducted to investigate the effect of lasalocid (Bovatec®) on ruminal degradation of dietary protein in Holstein steers. Five ruminally and duodenally cannulated steers (305 kg) were fed a corn-alfalfasoybean meal diet (17% CP), with or without lasalocid, in a three period, switch-back experiment. Ruminal pH, ammonia, volatile fatty acids, and amino acid and peptide concentrations were unaffected by lasalocid. Lasalocid reduced (P<.05) ruminal protease activity by 15%, but did not change deaminase activity. Digestibilities of dry matter, organic matter, fiber, and crude protein were similar between treatments. Intestinal flows of microbial and feed crude protein fractions, as well as amino acids, remained unchanged when lasalocid was fed. Thus, in this experiment, lasalocid failed to decrease feed protein degradation in the rumen and, therefore, was unable to increase the supply of crude protein or amino acids to the small intestine.; Dairy Day, 1994, Kansas State University, Manhattan, KS, 1994;
