“…In this study the ME density was obtained by a combination of a mature plant and a considerable amount of grain: 390 g ears per kg fresh material, on a DM basis (Brosh et al, 1989). The proportion of net energy to ME may be different between these two silages.…”

The effect of source of nitrogen used for supplementation of high wheat silage diets for cattle. ABSTRACTFive diets of identical metabolizable energy (ME) content were formulated, in which wheat silage, made from a variety bred for a high proportion of ears to roughage, was incorporated at the rate of 480 g/kg dry matter (DM). Their calculated ME density was 11-4 MJ/kg DM, the protein concentration of four of the five diets was 150 g/kg DM, and that of the fifth was 87 g/kg DM. The effectiveness of protein supplementation of such diets by non-protein nitrogen (NPN), fish meal (FM) or soya-bean and cottonseed oil meals (SBM and CSM) was studied in a digestibility and nitrogen balance trial, and in a feeding trial using Friesian and beef breed young bulls. One diet served as a negative control (NC). The apparent digestibility of organic matter (kg/kg DM) was 0-709, 0-708, 0-704, 0-680 and 0-667 (s.e. 00125) and nitrogen retention (g/kg M 075 per day) was 0-20, 0-65, 0-65, 0-64 and 0-68 (s.e. 0-059; P < 0-01) for the NC, NPN, FM, CSM and SBM supplemented diets, respectively. The feeding trial was divided into two periods; the first 100 days, and from day 101 to slaughter. The NC groups of both breeds gained significantly less in both periods of the experiment than did the supplemented groups. There were no significant differences among the supplemented groups.
