Extract

Nutritional deficiencies can have profound effects on the fertility and economic viability of dairy cattle. Phillippo et al. (1987) reported that molybdenum in the diet reduced the copper status of cattle and also delayed the onset of puberty, decreased the conception rate and caused anoestrus in cattle. A trial was set up at the University of Leeds farm to test the effect of supplementation with a soluble-glass bolus containing copper, cobalt and selenium on the reproductive performance of cattle.
