Energieaanvulling by melkkuilvoer vir slaglampproduksie

Abstract

Six different ratios of maize supplementation to maize silage were evaluated lor slaughter lambs in 2 experiments. Maize silage, supplemented at l/o of mean live body mas with maize, resulted in the highest growth rate tn the first experiment, whereas no significant differences occurred in the second. Carcass mas and dressing percentage were significantly higher on higher concentrated rations. Dry matter intake amounted +/- 3% of body mass. Excellent profit margins were shown for all the rations. lt is concluded that maize silage can play an important role in finishing early-weaned lambs for slaughter lamb production.

Twee eksperimente is uitgevoer waar kuilvoer met verskillende hoeveelhede mieliegraan aangevul is. Aanvulling, teen 19% van die lewende massa, het die beste resultate met betrekking tot groeitempo gelewer, terwyl beter karkasgradering by die hoer kragvoerrantsoene behaal is. Droemateriaahnname was 3/o van die lewende massa. Besondel gunstige wins bo voerkoste is behaal.
