Context In New Zealand, cows are usually milked twice a day (TAD), but in ~8% of herds, cows are milked once a day (OAD) for the entire lactation. If a genetic correlation (rg) of the same trait expressed in two environments (such as TAD and OAD) is

Selection scheme designs for dairy cattle milked once daily in New Zealand: a deterministic approach
Publikováno v:
New Zealand Journal of Agricultural Research. 64:127-142
In New Zealand, a specific selection scheme for the dairy cattle population milked once-a-day (OAD) has not been implemented. This study aims to investigate estimated genetic progress for different...

The objective of this study was the estimation of genetic correlation (rg) for milk production traits across milking frequency (MF) in New Zealand dairy cattle milked once-(OAD) or twice-a-day (TAD). Analysis was made of lactation yields of milk, fat

Production and efficiency of Holstein-Friesian (F), Jersey (J) and crossbred F × J milked once-a-day (OAD) were studied at Massey University dairy farm No. 1. Herd test records of milk yields, somatic cell score (SCS), live weight (LW) and body cond

The objective of this study was to compare Holstein-Friesian (F), Jersey (J) and crossbred (F × J) cows milked once-a-day (OAD) or twice-a-day (TAD) in New Zealand for milk, fat and protein yield, lactation persistency and average somatic cell score
