The objective of this trial was to evaluate performance, thermal comfort and behavior of crossbred Holstein x Zebu dairy calves kept in different housing systems during the dry season (26/04/2002 to 30/08/2002). Twenty-four calves were raised from birth to 70 days of age in one of the following housing systems: (1 – hutches; 2 – shadecloth; or 3 – with no shelter. Calves raised with no shelter showed higher rectal temperatures and respiratory rates in the afternoon. It was also […]

The objective of this trial was to evaluate performance, thermal comfort and behavior of crossbred Holstein x Zebu dairy calves kept in different housing systems during the rainy season (December to April). Twenty-four calves were raised from birth to 70 days of age in one of the following housing systems: hutches; shadecloth; or no shelter. Rectal temperature and respiratory rate measurements were taken twice a day (8:00 AM and 3:00 PM) when calves were 1, 4 and 9 weeks old. […]
