Abstract:
Silages made of Deganit wheat (DT), Halamish (HS) and American J × 180 (J) maize hybrids were incorporated in high proportions in the diets of growing fattening male cattle. Crude protein, acid detergent fibre (ADF) and lignin content of the silages were 10.7, 8.2, 7.1 and 40.6, 31.2, 25.8 and 11.8, 4.8, 3.9 for DT, HS and J × 180 silages, respectively. Dry matter (DM) intake (g) per kg metabolic weight (W0.75) was 73.8, 74.7 and 80.1, respectively, and in vivo digestibility coefficients of organic matter (OM; %) were 72.3, 73.6 and 76.3, respectively. The metabolizable energy (ME) values (MJ kg-1 DM) were 10.5, 10.6 and 11.2 for DT, HS and J silages, respectively. Four feeding trials in which 35-60% wheat silage or 60-75% maize silage (DM basis) was incorporated in the diets, indicate high daily gains (1.25-1.35 kg) and no effect to a difference of 15% silage DM in the diet or to its ME density, until a live weight of approximately 350 kg is reached. At higher live weights daily gain was reduced rapidly (1.00-1.15 kg), and the rate of decline was directly related to the proportion of silage in the diet and inversely related to its energy density. © 1989.
