“…At weaning, plasma TCh was significantly higher in PM sired cattle compared with those sired by CH (P < 0.05; Table 5); BB cattle showed intermediate levels. Previous studies have also shown that plasma TCh was higher in DM than in normal cattle (Basarab et al 1982). A similar sire effect was detected for plasma HDLCh and TG, the progeny of PM bulls had higher levels than the progeny of CH bulls.…”

Seoane, J. R., Lapierre, H. and Roy, G. L. 1999. The use of double-muscled cattle breeds in terminal crosses: Animal performance and blood metabolites. Can. J. Anim. Sci. 79: 293-299. Eighty-nine calves born of dams from British (50% Hereford and 50% Red Angus) and Continental (50% Simmental and 50% Maine Anjou) breeds crossed with Charolais (CH), Belgian Blue (BB) and Piedmontese (PM) sires were used to evaluate the productivity of using double-muscled cattle in terminal crosses. Breed of sire did not exert a significant effect on any parameter measured before weaning. Calving difficulty was related to breed of dam, being higher in British than in Continental dams (P < 0.05) and tended to be higher for male than for female calves (P < 0.10). Average daily gains to weaning and weight corrected at 200 d were higher for male than for female calves (P < 0.05), and for calves from Continental dams than for those from British dams (P < 0.05). Average daily gain during backgrounding was higher for CH than for PM-sired calves (P < 0.05). Also, ADG in feedlot (backgrounding + fattening ) was higher for male than for female calves (P < 0.05). Slaughter weight and dressing percentage were higher in calves from Continental dams than in those from British dams (P < 0.05). At similar backfat thickness, slaughter weight was higher in male than in female calves (P < 0.05). Total plasma cholesterol, HDL cholesterol and triglycerides were higher in PM sired cattle than in those sired by CH (P < 0.01 to 0.10). Similarly, cattle from British dams presented higher values of plasma cholesterol, HDL cholesterol and LDL cholesterol than cattle from Continental dams (P < 0.01 to 0.05). Insulin and IGF-I values increased with age (P < 0.01). Plasma insulin concentrations during fattening were higher for PM than for BB or CH sired cattle (P < 0.05), for cattle from Continental than from British dams (P < 0.01) and for males than for females (P < 0.01). During fattening, IGF-I values were higher in male than in female cattle (P < 0.01). The use of double-muscled sires in terminal crosses resulted in little effect on performance of the progeny. Quatre-vingt-neuf veaux issus de mères des races anglaises (50% Hereford et 50% Red Angus) et continentales (50% Simmental et 50% Maine Anjou) croisées avec des taureaux Charolais (CH), Blanc-Bleu Belges (BBB) et Piémontais (PM) ont été utilisés afin d'évaluer la productivité de croisements terminaux avec des taureaux des races à double musculature. La race du taureau n'a eu aucun effet sur les paramètres mesurés avant le sevrage. La difficulté au vêlage était reliée à la race de la mère, étant plus élevée pour les races anglaises que pour les races continentales (P < 0,05) et avait tendance à être plus élevée pour les veaux mâles que pour les femelles (P < 0,10). Le gain moyen quotidien (GMQ) jusqu'au sevrage et le poids corrigé à 200 jours étaient plus élevés pour les veaux mâles que pour les femelles (P < 0,05), et pour les veaux des mères continentales que pour ceux des mères anglaises (P < 0,05...
