Influence of the cow trainer on oestrous symptoms in dairy cows. 2. Ovarian function and frequency of silent heat (evaluation of progesterone profiles)

Influence of the cow trainer on oestrous symptoms in dairy cows. 2. Ovarian function and frequency of silent heat (evaluation of progesterone profiles)

Tierarztliche Umschau 44(2): 72, 75-78

In 68 dairy cows kept on short standings with a cow trainer, duration of acyclia post partum was significantly longer (34.3 +or- 17.8 vs. 27.8 +or- 14.1 days), ovarian dysfunctions (mainly ovarian cysts) occurred more frequently (20.5 vs 12.1%), the frequency of silent heat was higher (69.3 vs. 56.5%), and there was a higher percentage of false observations of oestrus (28.6 vs. 14%) than in 58 cows on standings without a trainer.
