Regression coefficients of milk production traits and fertility on homozygosity in Holstein and Jersey breeds
| Trait | Holstein | Jersey | ||
|---|---|---|---|---|
| b 1 (s.e.) | -log10(P-value) | b 1 (s.e.) | -log10(P-value) | |
| Milk (L) | -63.0 (14.9) | 4.6 | -71.0 (15.1) | 5.6 |
| Fat (kg) | -3.0 (0.6) | 6.4 | -3.9 (0.7) | 6.5 |
| Protein (kg) | -2.0 (0.5) | 4.3 | -2.8 (0.56) | 6.9 |
| Calving interval (d) | 0.93 (0.43) | 1.5 | 0.30 (0.6) | 0.21 |
b1: Regression coefficient and associated standard error (s.e.) estimated using homozygosity defined as the proportion of homozygous SNPs for milk, fat and protein yields and calving interval as a measure of fertility.
