Abstract:
Nulliparous Israeli Holstein heifers were inseminated in 111 high-producing dairy herds with 9411 doses of semen from 26 proven sires of five national strains: Canada (CA), New Zealand (NZ), Sweden (SW), Israel (IS) and United States (US); 4914 calves were born and 1483 F1 daughters were milk recorded. Significant differences among strains were found for all traits analyzed. Mates of NZ sires and daughters of IS sires were most favorable for calving traits and mates of SW sires and daughters of CA sires were least favorable. NZ daughters were smallest, and CA daughters were largest and most favorable for udder conformation traits. SW daughters were least favorable for conformation traits, but had the highest conception rate. US daughters had the lowest conception rate. The ranges of strain effects for milk, fat and fat percentage were 1551 kg, 27 kg and 0.28%, respectively. IS daughters were highest for dairy character and milk and fat production, but lowest in fat percentage. NZ daughters were lowest in milk and fat production, but highest in fat percentage. The correlations between predicted differences for kg fat and kg milk and fat percentage were 0.96 and -0.85, respectively. Within-strain correlations between sire evaluations for milk in each of the countries of origin and IS were 0.84, 0.80, 0.51 and 0.01, for US, SW, CA and NZ, respectively. The results provide a basis for comparison of sire evaluations among US, CA, SW and IS. © 1987.
