“…Clearly, the possibility of differences existing between different breeds, as indicated by ARC (1980), cannot be discounted. From the results of these studies the low CP requirement of 90 g/kg diet or less in the final part of the finishing process as suggested by Young (1969) and by Putnam, Oltjen and Bond (1969) for steers, and by Williams, Vetter, Burroughs and Topel (1975) for bulls, may be adequate only when live weight exceeds 400 kg.

The effect of source of nitrogen and level of its supplementation on the performance of growing-fattening bulls. ABSTRACTTwo feeding trails were made and in both all the diets given contained about 11 MJ metabolizable energy (ME) per kg dry matter (DM).In trial 1, diets containing three concentrations of crude protein (CP) were given to a total of 84 Friesian bulls in each of three stages of growth. They were, in stage 1 (150 to 250 kg live weight) 130, 145 and 160 g CP per kg dietary DM; in stage 2 (250 to 350 kg live weight) 110, 130 and 145 g CP per kg dietary DM; in stage 3 (350 kg to slaughter) 95, 110 and 130 g CP per kg dietary DM. In stages 2 and 3, the source of supplementary nitrogen at each CP concentration was either soya-bean meal or non-protein nitrogen (NPN) giving six combinations of concentration and source of dietary CP. Liveweight gains in stage 1 were 1-52, 1-60 and 1-58 kg/day respectively (P > 005). In the stages involving both concentrations and source of nitrogen (soya-bean meal in parentheses), the mean daily live-weight gains were (06) and 1-08 kg for stage 3 (P < 005), for the diets of 130, 145 and 160 g CP per kg diet respectively.Trial 2 consisted of six stages of growth, the first five of 45 days duration and the sixth of varying length up to a predicted slaughter weight, and seven dietary treatments. Treatment 1 was a negative control (NC) with a dietary CP concentration of 90 g/kg DM. For the other six treatments two concentrations of dietary CP were given; 120 g/kg and 140 g/kg in stages 1 and 2 and 100 g/kg or 120 g/kg in stages 3 to 6. Dietary CP concentration was increased by the addition of NPN, fish meal or soya-bean meal. A total of 98 Friesian bulls were used with an initial average live weight of 185 kg. Daily gain of the NC group in the six stages of the trial was 0-86, 0-97, 101, 1-13, 1-07 and 1-00 kg for stages 1 to 6 respectively. From the results it was concluded that feeding NPN is not efficient at live weights lower than 250 kg and that there is no advantage to feeding fish meal over soya-bean meal in diets of medium energy concentration at live weights heavier than 250 kg.

“…(Steel and Torrie, 1960) and Duncan's multiple range test (Duncan, 1955 Performance, at each period, for steers withdrawn from supplemental protein (13-11-9% treatment) at day 84 was similar to performance of steers fed supplemental protein for the entire trial. Other researchers Cahill, 1972, 1973;Putnam, 1969;and Riley and Harrison, 1975) have also reported that protein levels in the ration of finishing steers can be reduced during the feeding period without affecting feedlot performance. Feeding protein at levels greater than 11% did not result in improved steer performance at any time during the trial.…”

“…Daily gains were shown to increase with the addition of 3 to 5% fat to steer rations (Erwin et al, 1956;Bohman et al, 1957). Others have observed a decrease in gains of steers receiving 5% added fat (Wise et al, 1959;Putnam et al, 1969). Perry et al (1976) reported no effect from the addition of fat to high moisture beef cattle diets.…”

Three feedlot studies were conducted with growing-finishing beef cattle to compare the nutritional value of soybean meal (SBM), hydrolyzed feather meal (FM) and hydrolyzed hog hair meal (HM) as sources of supplemental protein. Eight different pelleted protein supplements were formulated by replacing 25 to 100% of the SBM protein in a control supplement (Supplement A) with FM and/or HM protein. Approximately 8 to 30% of the dietary crude protein (CP) in 12.5% CP diets (dry basis) was supplied by FM and/or HM protein in the various experiments. Steer calves (Experiment 1) receiving a corn silage-high-moisture corn diet supplemented with various protein supplements containing 19 or 31% FM or HM exhibited no significant differences in daily gains, feed efficiency, feed consumption or carcass characteristics. Addition of .23 kg of feed grade fat to each supplement type did not significantly affect daily gains or carcass characteristics. Steers receiving added fat consumed significantly less (13%) dry matter (DM) than did steers receiving no additional fat. Heifer calves (Experiment 2) fed a corn silage-cracked corn diet supplemented with protein supplements containing either 9 or 19% FM or HM or containing 9% of both FM and HM were significantly less efficient in converting dry feed to gain than were heifers receiving a SBM supplement. There were no significant differences in gains, feed consumption or carcass characteristics of heifers receiving the different l Journal Collins 80523. supplement types. Steer calves (Experiment 3) receiving a high moisture ground ear corn diet and either a SBM or one of three types of FM supplements containing 10, 19 or 29% FM exhibited no significant differences in average daily gains.
