“…In a New Zealand study, Muir et al (2000) found that despite differences in size, conformation and fatness between Hereford, Friesian and Hereford cross Friesian steers, overall yield of saleable high value cuts (cube roll, striploin and tenderloin expressed as a percentage of total carcass weight) was similar between breeds when slaughtered at the same weight or level of maturity. Similar results were reported by Barton (1971Barton ( , 1972, Truscott et al (1976), Everitt et al (1980), Bass et al (1981), Nour et al (1981Nour et al ( , 1983b, Bertrand et al 1983, Patterson et al (1985, Stiffler et al (1985) and Butler-Hogg et al (1988). Branaman et al (1962) found no significant difference in the total percentage of rib, round and loin cuts in Holstein and Hereford steer carcasses.…”

Despite the heavy reliance of the New Zealand beef industry on animals produced from the dairy industry (predominantly Friesian and Friesian cross), there is a widespread belief that beef of dairy origin is inferior to beef produced from traditional 'British' breeds. This belief is not supported by the scientific literature. There is a large body of work that suggests there is no difference between dairy and traditional British beef breeds in growth potential, lean meat yield, yield of prime cuts, and the quality of meat produced when grazed under similar conditions and slaughtered at the same chronological age or the same level of maturity (fatness). The current New Zealand payment schedule based on carcass weight, fatness and muscularity, undervalues dairy carcasses for having a different pattern of fat distribution (i.e. less subcutaneous fat) and a different muscle shape (poorer conformation score). In New Zealand, the key commercial driver for using traditional beefbred cattle appears to be their ability to achieve the 3 mm minimum fat depth and therefore a prime-graded carcass at a lighter carcass weight and with a younger animal compared to dairy-bred cattle.

“…Some heritability estimates for growth and carcass composition of purebred and beef-cross Friesian steers were reported by Everitt et al (1980). From their estimates, it was clear that sire variation for EMA was appreciable in the sample of 30 sires in each of 4 years.…”

Breed and heterosis effects for growth and some carcass characteristics were estimated from purebred Angus (A x A), purebred Hereford (H x H), and crossbred (H x A and A x H) steers bred at the Waikite Land Development Block near Rotorua over a 4-year period. Data from 477 steers alive at 5-month weaning and 445 steers slaughtered at 20 monthsof-age were analysed. Age of dam and age of calf were significant non-genetic effects for all liveweights, 20-month carcass weight, and eye muscle area. The age of dam effect was not significant for average fat depth over the 12th rib of the carcass, but age of calf showed a significant effect.' At a constant slaughter age (618 days) steers by Hereford sires had a higher slaughter liveweight, carcass weight, and dressing-out percent than those by Angus sires. Steers out of Hereford cows relative to those from Angus cows were heavier at slaughter and had heavier carcasses but there was no significant effect of cow breed on other carcass traits. At a constant hot carcass weight (169 kg), eye muscle area was larger for steers sired by Angus bulls or out of Angus dams, with little effect of sire breed or dam breed on the other carcass traits. Comparison of purebred calves with the reciprocal crosses showed significant (P< 0.001) heterosis for empty liveweight before slaughter (8.4%), hot carcass weight (10.4070), dressing-out percent (1.9%), fat depth (26.5%), eye muscle area (6.1%), and export carcass grade ( -10.2%), when evaluated at a constant slaughter age. At a constant hot carcass weight, heterosis was significant (P< 0.05) for dressing-out percent (0.7%) and fat depth (13.7%). Paternal half-sib heritability estimates increased from 0.19 for 5-month weaning weight to 0.62 for 20-month empty liveweight and 0.60 for hot carcass weight. Heritabilities for carcass traits at a constant slaughter age were moderate to low: fat depth (0.26), dressing-out percent (0.23), export carcass grade (0.39), and eye muscle area (0). Genetic and phenotypic correlations among steer liveweights recorded from weaning to 20 months-of-age and hot carcass weight were high and positive (0.64-0.97). Phenotypic correlations of final liveweight with dressing-out percent, fat depth, and eye muscle area were all moderate to low and positive. Genetic correlations of fat depth with final liveweight or hot carcass weight were negative.

“…The components of variance were estimated by applying method 3 of H ENDERSON (H ENDERSON , 1953) separately for both stations, and within sire-breed at Midatest. (A DAMS et al, 197 3 ;B IBE et al, 1973B IBE et al, , 1976 ; AN DER SEN et al, 1977 ;KOCH & DI KEM A N , 1977 ;IZ OBELIN et al, 1978 ;E VERITT et al, 1980 ;BASS et al, 1981 ;FR EBLING et al, 1982 ;L IBO -RIUSSEN et al, 1982 ;M ENISSIER et al, 1982 (R ENAND , 1985). Genetic variability of the rib eye area at Midatest (H 2 = .33) was slightly less (by .10 point) than the mean of bibliographic data at constant weight (R ENAND , 1983).…”
