Introduction
Numerous studies across multiple locations support the concept that lactating cows exposed to 16 to 18 hours of light each day (i.e., long day photoperiod, or LDPP) have greater milk yield relative to cows on a typical light schedule of natural photoperiod plus some additional light to accommodate milking on a 12:12-hour schedule (reviewed in Dahl et al., 2000). The increase in milk ...

Introduction Traditionally, management of cows during the dry period was minimal. Approximately 60 days before calving, milking would cease and cows were treated with long lasting antibiotic in an attempt to clear up any lingering subclinical mastitis and prevent new infections. Cows were typically removed from the milking herd, given reduced feed, and often exposed to pasture and allowed to ...
