Interrelationships between ambient temperature, postpartum reproductive events and reproductive performance in dairy cows
[Page generation failure. The bibliography processor requires a browser with Javascript enabled.]
A path analytic approach was used to study data collected on 23 traits of 226 Holstein-Friesians in a commercial dairy herd during May 1981-Oct. 1982. Rectal palpation to assess uterine involution and ovarian activity was performed at 15, 24 and 28 days post partum, and blood samples were collected ...
