Autor: T.F. O’Callaghan, Michael G. Keane, Frank J. Monahan, A.P. Moloney

Publikováno v: Irish Journal of Agricultural and Food Research. 60

The influence of modifying a traditional 24-mo dairy steer calf to beef production system on the fatty acid composition of the longissimus muscle and its potential to authenticate beef provenance was examined. Fifty-four male calves (n = 18 per sire

Meat quality characteristics of high dairy genetic-merit Holstein, standard dairy genetic-merit Friesian and Charolais x Holstein-Friesian steers

Autor: Mark McGee, Michael G. Keane, Patrick J. Caffrey, Aidan P. Moloney, R. Neilan

The increased use of Holstein genetic material in the Irish dairy herd has consequences for beef production. In all, 42 spring-born steers [14 Holsteins (HO), 14 Friesian (FR) and 14 Charolais × Holstein-Friesian (CH)] were reared to slaughter at be

Autor: S. M. Keady, Michael G. Keane, A.R. Wylie, Edward G. O'Riordan, David A. Kenny, S. M. Waters, Kate Keogh

Publikováno v: Animal, Vol 15, Iss 6, Pp 100215-(2021)

Compensatory growth (CG) is the ability of an animal to undergo accelerated growth after a period of restricted feeding. However, there is a dearth of information in relation to the effect of genotype on CG response, thus the objective of this study

Beef production from Holstein–Friesian, Norwegian Red×Holstein–Friesian and Jersey×Holstein–Friesian male cattle reared as bulls or steers

Autor: Michael G. Keane, E.G. O’ Riordan, David A. Kenny, Frank Buckley, A. McNamee, A.P. Moloney

Publikováno v: Livestock Science. 173:95-105

The Norwegian Red and Jersey dairy breeds have been evaluated for crossbreeding with Holstein–Friesian dairy cows in Ireland. If such crossbreeding becomes common practice, the resultant male calves will enter the beef industry. The objective was t
