Fibre-type characteristics and postmortem glycolysis of bison (Bison bison bison) longissimus lumborum
Download2002
Aalhus, J. L., Janz, J. A. M., Price, M. A.
To augment the limited information base, muscle fibre and postmortem glycolytic data from bison longissimus lumborum were compiled. As expected, postmortem glycogen concentration and pH declined while lactate concentration increased. Bison muscle fibres had a greater area, with a greater...

Gene co-expression network analysis identifies porcine genes associated with variation in Salmonella shedding
Download2014
Plastow, G. S., Bearson, S. M. D., Arantes, A. S., Bao, H., Kommadath, A., Stothard, P., Guan, L. L., Tuggle, C. K.
Background Salmonella enterica serovar Typhimurium is a gram-negative bacterium that can colonise the gut of humans and several species of food producing farm animals to cause enteric or septicaemic salmonellosis. While many studies have looked into the host genetic response to Salmonella...

Genetic parameters for production and feeding behaviour traits in crossbred steers fed a finishing diet at different ages
Download2013
Wang, Z., Nkrumah, D. J., Basarab, J. A., Durunna, O. N., Okine, E. K., Moore, S. S., Mujibi, F. D. N.
Because cattle can be raised postweaning under several feeding regimes, this study examined the consistency of phenotypic and genetic parameters of some production and feeding behaviour traits between two feeding periods that beef cattle received a finisher diet. Crossbred steers (n=851) were...

Aalhus, J. L., Yambayamba, E. S. K., Price, M. A., Jones, S. D. M.
Twenty-four Hereford crossbred heifers weighing 222 kg (22 kg SD) and aged 226 d (13 d SD) on day 0 were used to investigate the effects of feed restriction (period 1) followed by realimentation (period 2) on hepatic and longissimus muscle glycogen metabolites and meat quality. The heifers were...

Greenhouse gas emissions from calf- and yearling-fed beef production systems, with and without the use of growth promotants
Download2012
Baron, V. S, Aalhus, J. L., Basarab, J. A., López-Campos, Ó., Haugen-Kozyra, K., Okine, E. K.
A spring calving herd consisting of about 350 beef cows, 14–16 breeding bulls, 60 replacement heifers and 112 steers were used to compare the whole-farm GHG emissions among calf-fed vs. yearling-fed production systems with and without growth implants. Carbon footprint ranged from 11.63 to 13.22...

Kolbehdari, D., Stothard, P., Schnabel, R., Wang, Z., Marques, E., Taylor, J. F., Moore, S. S.
Background Linkage disequilibrium (LD) maps can provide a wealth of information on specific marker-phenotype relationships, especially in areas of the genome where positional candidate genes with similar functions are located. A recently published high resolution radiation hybrid map of bovine...

High resolution radiation hybrid maps of bovine chromosome 19 and 29 and comparison with the bovine genome sequence assembly
Download2007
Murdoch, B., Wang, Z., Stothard, P., Womack, J. E., Mckay, S. D., Moore, S. S., Schiex, T., Prasad, A.
Background High resolution radiation hybrid (RH) maps can facilitate genome sequence assembly by correctly ordering genes and genetic markers along chromosomes. The objective of the present study was to generate high resolution RH maps of bovine chromosomes 19 (BTA19) and 29 (BTA29), and...

Identification of a putative quantitative trait nucleotide in guanylate binding protein 5 for host response to PRRS virus infection
Download2015
Choi, I., Guan, L., Plastow, G. S., Liu, P., Koltes, J. E., Loyd, H., Boddicker, N. J., Eisley, C. J., Schroyen, M., Bao, H., Dekkers, J. C. M., Kommadath, A., Abrams, S. M., Reecy, J. M., Rowland, R. R. R., Serão, N. V. L., Lunney, J. K., Carpenter, S., Stothard, P., Fritz-Waters, E., Tuggle, C. K.
Background Previously, we identified a major quantitative trait locus (QTL) for host response to Porcine Respiratory and Reproductive Syndrome virus (PRRSV) infection in high linkage disequilibrium (LD) with SNP rs80800372 on Sus scrofa chromosome 4 (SSC4). Results Within this QTL,...

Increasing gene discovery and coverage using RNA-seq of globin RNA reduced porcine blood samples

Stothard, P., Fritz-Waters, E., Choi, I., Abrams, S. M., Kommadath, A., Hosseini, A., Plastow, G. S., Guan, L. L., Tuggle, C. K., Bao, H., Meng, Y., Lunney, J. K., Reecy, J. M., Sun, X.
Background Transcriptome analysis of porcine whole blood has several applications, which include deciphering genetic mechanisms for host responses to viral infection and vaccination. The abundance of alpha- and beta-globin transcripts in blood, however, impedes the ability to cost-effectively...

Meat quality of bison (Bison bison bison) Longissimus thoracis et lumborum following very fast chilling
Download2002
Aalhus, J. L., Janz, J. A. M., Price, M. A.
Very fast chilling (VFC; internal muscle temperature of -1°C by 5 h postmortem) was achieved in the longissimus lumborum (LL), but not in the semimembranosus, of lean bison carcasses after only 4 or 6 h of chilling at -35°C. Rigorous chilling caused a shift in moisture loss from carcass cooler...
