  • ISSN : 0302-7104



The influence of two planes of nutrition (High-H and Moderate-M) over two winters, from weaning to mating, was studied in 46 Afrikaner x Sussex heifers. The calving percentage, weaning mass of their calves and margin above feed costs of the H-group heifers were 17%, 17 kg and 70% above those of the M-group heifers. Plane of nutrition had no effect on oestrous cycle length (x=20,6 days).
