Abstract


Three types of housing systems i.e. open, semi-open, and closed barns for logical dairy cattle (PFH) calves, heifers and lactating cows were used in this study. The study was conducted partly in the Department of Dairy Science UGM and partly on Z0 dairy farms in the Yogyakarta area (DIY) in either the dry or wet seasons of I994, 1995, and 1996. Data on physiological measurements, bam microclimate, feed intake, and productivity were collected. The results showed that most measurements of physiological status or productivity were not affected by type of housing. There were no effects on concentrate on forage intake, water intake, daily weight gain, or milk production. Bam microclimate was affected by housing systems especially relative humidity and barn air temperatures. However, possible environmental stressors were
apparently within limits that could be overcome by self-regulation of some physiological functions by these adapted PFH cattle.
