The economic importance of reproductive performance


, : The economic importance of reproductive performance. Producteur de Lait Quebecois 13(3): 30-32

Reproductive performance of dairy cows is assessed on the basis of calving-conception interval, calving interval, conception rate and rate of detection of oestrus. Models were developed using hypothetical dairy herds to correlate reproductive performance with annual milk yield, lactation curves, calf production, insemination costs and replacement rates.

The inhibitory effect of the fresh juice of kale on the genotoxicity induced by aflatoxin B-1 (AFB-1) in Salmonella and Drosophila was investigated. The kale juice had strong inhibitory activity for His- to His+ reverse-mutations induced by AFB-1...

To determine whether additional hypertrophy would be beneficial or maladaptive in cardiac failure, the effects of insulin-like growth factor (IGF-1) were investigated in rats with left ventricular (LV) dysfunction. In normal rats, 3 mg/kg per d of...
