Maize meal supplementation to young steers on summer veld and different planes of nutrition during winter:

The influence of 2 planes of nutrition during winter as well as maize supplementation at different stages of growth of summer veld. On the growth and carcass quality of Hereford x Africander steers were investigated over one and 2 years respectively. The wintering of steer above maintenance (0.57 kg gain/day) yielded a significant (P <0,01) increase in live mass, carcass mass and carcass quality, compared to wintering at maintenance. The daily supplementation of steers with maize meal at 1,4 kg for the first and 1,8 kg for the second summer, compared to no maize, resulted in a significantly (P < 0,05) heavier carcass mass for steers wintered above maintenance. Supplementation of maize meal resulted in an increased grading (P < 0,01) only when steers were slaughtered after the first summer. No significant (P < 0,05) differences in fat thickness and rib-eye area occurred as a result of maize supplementation. The supplementation of maize only after semination of the summer grass compared to the whole summer did not influence results significantly. The highest yearly income above feed costs occurred where steers were winter above maintenance, received maize meal for the last half of summer and were slaughtered after the first summer.
