Table 5.
Least square means and standard errors for body temperature for fixed effects year, and day (yr)
| Effect | Year | Day | Estimate, ˚C | SE | Heat load | Heterosis |
|---|---|---|---|---|---|---|
| Year | 2017 | 38.85 | 0.008 | |||
| Year | 2018 | 38.77 | 0.006 | |||
| Day(Year) | 2017 | 1 | 38.81a | 0.015 | 40 | 0.02 |
| Day(Year) | 2 | 38.84a | 0.011 | 46 | −0.01 | |
| Day(Year) | 3 | 38.89b | 0.013 | 44 | 0.01 | |
| Day(Year) | 2018 | 1 | 38.67a | 0.010 | 27 | −0.17 |
| Day(Year) | 2 | 38.81b | 0.009 | 34 | −0.14 | |
| Day(Year) | 3 | 38.83b | 0.011 | 35 | −0.13 |
a,bWithin a column, least square means for day within the same year with the same superscript letter are not significantly different; those with different letters are significantly different with P ≤ 0.05.
