Descriptive statistics for the studied Swedish cattle breeds
| Breed | N samples | Type (distribution) | Characteristic | Citation |
|---|---|---|---|---|
| FNC | 16 | Native (north) | Smaller body size than the Fjäll breed; lower milk yield; said to be hardy and hold strong ability to find food in natural pastures | [16] |
| SMC | 23 | Native (north) | Small body size of cows about 400-450 kg; said to be hardy and hold strong ability to find food in natural pastures | [16] |
| SHF | 24 | Commercial (south) | The old Friesian type was more of a dual-purpose; the SHF is a commercial dairy breed with live weight of cows around 700 kg | [16] |
| SRC | 25 | Commercial (south middle to south) | A commercial dairy breed; live weight of cows 550–650 kg | [16] |
| SRP | 18 | Native (middle) | The focus is on conservation; said to be hardy; live weight of cows 350–600 kg | [16] |
Breed: FNC (Fjällnära Cattle), SMC (Fjäll also known as Swedish Mountain Cattle), SHF (Swedish Holstein–Friesian), SRC (Swedish Red Cattle), SRP (Swedish Red Polled)
N samples: number of genotyped samples (i.e. before data quality control); note that according to data quality control, four samples (due to animal call-rate < 0.95) were removed, and principal component (PC) analyses, three samples (due to locating outside their expected breed cluster) were removed; resulting in 99 individuals for analyses of selection signatures
