The relationship between early lactation hoof lesions and behavior, inflammatory mediators, and reproductive performance in dairy cows.

 

Team: Cramer Bisinotto, Omontese, Wynands

Funding Sources:  Rapid Agricultural Response Fund

Project Time Frame:  2016-2019

The goal of this project is to elucidate the mechanisms by which hoof lesions affect behavior, inflammatory status, and specific reproductive parameters in lactating dairy cows.

The specific objectives of this project are to assess the effects of new cases of hoof lesions on:

1.     Behavioral parameters of cows such as lying time, resting bouts, and activity;

2.     Expression of inflammatory mediators by peripheral blood leukocytes (PBL) and their concentrations in blood;

3.     Reproductive parameters such as estrus detection rate, pregnancy per AI (P/AI), risk of pregnancy loss, and time to pregnancy in lactating dairy cows.
