Dominant Red Coat Color in Holstein Cattle Is Associated with a Missense Mutation in the Coatomer Protein Complex, Subunit Alpha (COPA) Gene

Sällman Almén, M., Liao, X., Stothard, P., Henegar, C., Van Doormaal, B., Rubin, C. -J., Andersson, L., Barsh, G. S., Ito, S., Plastow, G., Wakamatsu, K., Dorshorst, B.
Coat color in Holstein dairy cattle is primarily controlled by the melanocortin 1 receptor (MC1R) gene, a central determinant of black (eumelanin) vs. red/brown pheomelanin synthesis across animal species. The major MC1R alleles in Holsteins are Dominant Black (MC1RD) and Recessive Red (MC1Re). A...

Effects of calf- and yearling-fed beef production systems and growth promotants on production and profitability
Download2013
Baron, V. S., López-Campos, O., Aalhus, J. L., Basarab, J. A., Okine, E. K.
In each of 2 yr, 112 spring-born steers were used to evaluate the effect of calf-fed vs. yearling-fed with and without growth implant and β-adrenergic agonist on production parameters and economic potential. Steers were grouped into: (1) non-implanted feeders harvested at 11–14 mo of age, (2)...

Effects of production system and growth promotants on the physiological maturity scores in steers
Download2014
Aalhus, J. L., Basarab, J. A., N. Prieto, I. L., López-Campos, Ó., Larsen, M.
Over a 2-yr period, 224 crossbred steers were allotted to a 2×2×2 factorial arrangement of treatments to determine the effect of the production system (calf-fed vs. yearling-fed), growth implant strategy (non-implanted vs. implanted) and β-agonist supplementation (no ractopamine vs. ractopamine)...

Meghen, C. N., Platz, S. S., Hu, X. S., Moore, S. S., Simila, J., Plastow, G.
Estimating animal abundance in industrial scale batches of ground meat is important for mapping meat products through the manufacturing process and for effectively tracing the finished product during a food safety recall. The processing of ground beef involves a potentially large number of...

Expansion of ruminant-specific microRNAs shapes target gene expression divergence between ruminant and non-ruminant species
Download2013
Kommadath, A., Bao, H., Meng, Y., Plastow, G. S., Stothard, P., Sun, X., Arantes, A. S., Guan, L. L.
Background Understanding how species-specific microRNAs (miRNAs) contribute to species-specific phenotypes is a central topic in biology. This study aimed to elucidate the role of ruminant-specific miRNAs in shaping mRNA expression divergence between ruminant and non-ruminant species. ...

Gene co-expression network analysis identifies porcine genes associated with variation in Salmonella shedding

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 and Phenotypic Correlations between Performance Traits with Meat Quality and Carcass Characteristics in Commercial Crossbred Pigs
Download2014
Wang, Z., Kemp, R., van Haandel, B., Charagu, P., Zhang, C., Bruce, H., Miar, Y., McKay, R., Huisman, A., Plastow, G., Manafiazar, G., Moore, S.
Genetic correlations between performance traits with meat quality and carcass traits were estimated on 6,408 commercial crossbred pigs with performance traits recorded in production systems with 2,100 of them having meat quality and carcass measurements. Significant fixed effects (company, sex...

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...

Voort, G. V., Sargolzaei, M., Wang, Z., Moore, S., Mandell, I., Lu, D., Kelly, M., Plastow, G., Miller, S.
Background Genetic improvement of beef quality will benefit both producers and consumers, and can be achieved by selecting animals that carry desired quantitative trait nucleotides (QTN), which result from intensive searches using genetic markers. This paper presents a genome-wide association...
