Breeding of dairy cows on pasture

KB Mitteilungen 28(2): 12-16

Breeding of dairy cows on pasture

A summary of cattle breeding in New Zealand is given. In 1989 there were 13 800 dairy farms with a total cattle population of 2.2 million dairy cows (av. herd size 160). Most purebred animals were of the Holstein, Jersey and Ayrshire breeds, but Jersey X Holstein crossbreds were also common. Breeding was seasonal, with all cows calving within a 6- to 8-wk period around mid-Aug. Animals were inseminated 6-7 wk after calving, 90% of inseminations being with fresh semen.

In pasture-based dairy systems, daily time at pasture is restricted during several periods of the year. The aim of this experiment was to evaluate the effect of restricting time at pasture on milk yield, pasture dry matter (DM) intake, and grazing...
