Studies on the relationships between fertility and milk yield in heifers and first-calvers in the Rendsburg-Eckernforde district

, : Studies on the relationships between fertility and milk yield in heifers and first-calvers in the Rendsburg-Eckernforde district. Untersuchungen uber die Beziehungen zwischen Fruchtbarkeit und Milchleistung bei Farsen und Erstkalbinnen in einem Praxisgebiet im Kreis Rendsburg Eckernforde: 72

In 396 German Black Pied heifers on 25 farms, milk yield was correlated significantly to 1st insemination conception rate (r = -0.145) and number of inseminations needed for 1st conception (r = +0.145) and highly significantly to number of inseminations needed for 2nd calving (+0.169).

A major problem of ageing is progressive impairment of neuronal function and ultimately cell death. Since sex steroids are neuroprotective, their decrease with age may underlie age-related neuronal degeneration. To test this, we examined Purkinje...
