“…These results are similar to those of Root and Huhtanen (1998) who reported no significant differences when replacing barley grain partly with BF up to 350 kg LW with separate feeding. In the present trial, feed efficiency (kg DM kg -1 LWG) tended to be better with the BF0 than with the BF50 diet at stage 1.…”

“…In the present trial, feed efficiency (kg DM kg -1 LWG) tended to be better with the BF0 than with the BF50 diet at stage 1. Root and Huhtanen (1998) reported no difference in feed conversion up to 350 kg LW, but from 350 kg LW to slaughter replacing barley grain by BF reduced the feed conversion. These data indicate that during the early part of the growing period (LW 200 to 400 kg), 50% of barley starch can be replaced with BF without affecting growth or feed efficiency factors.…”

“…The average live weight gain (LWG) or carcass characteristics were not significantly different for the different BF replacements, but towards the end of the experiment (LW 350 -500 kg) the LWG of the bulls fed BF tended to decrease compared to barley grain (Root and Huhtanen 1998). With TMR feeding (concentrate proportion 570 g kg -1 DM), the LWG of the dairy bulls (initial LW 280 kg and final LW 675 kg) given BF tended to be higher than that of bulls given barley grain diets up to 500 kg LW when replacing half of the barley grain with BF (Huuskonen unpublished data).…”

“…The LWG was calculated as the difference between the means of initial and final weights. The estimated rate of carcass gain was calculated by assuming an initial carcass weight of 0.50 of initial LW which was used also in a previous study by Root and Huhtanen (1998). Dressing proportions were calculated from the ratio of hot carcass weight to final LW.…”

“…According to Root and Huhtanen (1998), with separate feeding (concentrate proportion 390 g kg -1 dry matter (DM)) including BF in the diet of growing bulls (initial live weight (LW) 205 kg and final LW 500 kg) did not affect feed or energy intake markedly. The average live weight gain (LWG) or carcass characteristics were not significantly different for the different BF replacements, but towards the end of the experiment (LW 350 -500 kg) the LWG of the bulls fed BF tended to decrease compared to barley grain (Root and Huhtanen 1998).…”

The objective of the present experiment was to study the effects of partial replacement of barley grain with barley fibre (BF) on animal performance, carcass traits and diet digestibility of growing dairy bulls. The feeding experiment comprised 20 Finnish Ayrshire bulls and 12 Holstein-Friesian bulls, and four treatments (8 bulls per treatment). There were four diets with two offered at stage 1 (from the initiation of the study to 450 kg live weight) and four at stage 2 (from 450 kg live weight to slaughter). The control diet (BF0) included grass silage (460 g kg -1 dry matter) and barley grain (540), BF25 diet included grass silage (460), barley grain (405) and BF (135), BF50 diet included grass silage (460), barley grain (270) and BF (270), and BF75 diet included grass silage (460), barley grain (135) and BF (405). At stage 1 there were only two treatments (BF0 and BF50) and at stage 2, all four treatments were included. All bulls were fed total mixed ration ad libitum. The mean initial live weight of the bulls was 261 kg and the mean final live weight 650 kg. At stage 1 there were no significant treatment differences in dry matter, energy or protein intakes or in live weight gain. At stage 2, replacing barley grain with BF led to a linear decrease of daily live weight gain (P < 0.05) and a linearly reduced feed conversion (kg dry matter kg -1 live weight gain) (P < 0.05). The apparent digestibility of the organic matter and neutral detergent fibre decreased linearly with increasing BF supplementation (P < 0.001). The dressing proportion and the carcass fat score decreased linearly (P < 0.05) with partial replacement of barley grain with BF. On carcass conformation, treatment had a significant (P < 0.05) quadratic effect: the BF25 and BF50 diets were classified highest. The results indicate that 50% of barley starch can be replaced with BF without affecting growth, but feed efficiency factors may decrease when barley starch is replaced with BF. At 75% replacement, feed intake was reduced, which resulted in a lower energy intake and reduced level of performance.

Production and carcass traits of purebred Nordic Red and Nordic Red×beef breed crossbred bulls

SUMMARYThe objective of the current study is to determine the beef production traits of purebred Nordic Red (NR) and NR×beef breed crossbred bulls. The data collected from slaughterhouses included observations of 164 812 purebred NR, 2329 NR×Aberdeen Angus, 1466 NR×Blonde d'Aquitaine, 1044 NR×Charolais, 782 NR×Hereford, 5293 NR×Limousin and 1270 NR×Simmental bulls. For estimating valuable cuttings, a separate dataset including a total of 16 827 observations was collected. Crossbreeding NR cows with late-maturing breeds (Blonde d'Aquitaine, Charolais, Limousin or Simmental) had favourable effects on carcass gain, conformation and proportion of high-value joints of the progeny when compared with purebred NR bulls. No advantages in proportion of valuable cuttings seemed to be obtained by crossbreeding with Aberdeen Angus or Hereford breeds, while the improvements in gain and conformation were intermediate compared with the late-maturing crossbreds. A feeding experiment comprised 36 bulls: nine purebred NR, nine NR×Aberdeen Angus (NR×Ab), nine NR×Limousin (NR×Li) and nine NR×Blonde d'Aquitaine (NR×Ba). The animals were offered total mixed ration (TMR) ad libitum. The dry matter (DM) of the TMR consisted of grass silage (500 g/kg DM), rolled barley (425 g/kg DM) and rapeseed meal (75 g/kg DM). There were no differences in DM, energy or nutrient intakes between NR and crossbred bulls during the feeding experiment. Instead, the carcass gain of the NR×Ba bulls was 13% higher than that of the pure NR bulls. In addition, the carcass gain of the NR×Li bulls tended to be 8% higher than that of the NR bulls. The feed (kg DM/kg carcass gain) and energy (MJ/kg carcass gain) conversion rates of the NR×Ba bulls tended to be better compared with purebred NR bulls. There were no differences in feed or energy conversion between NR, NR×Ab and NR×Li bulls. In conclusion, crossbreeding, especially with late-maturing bulls, largely improved carcass production compared with purebred NR bulls. The feeding experiment indicates that there is no difference in DM intake between pure NR and crossbred bulls when animals are fed with high-energy rations. Therefore, differences in growth and carcass traits describe well the economic superiority of crossbreds compared with pure dairy bulls from beef producers’ point of view.

A 2)2 factorial design with 32 dairy bulls was used to study the effects of partial replacement of a starchy concentrate with a fibrous concentrate and replacement of rapeseed meal with barley protein as protein supplement on performance of bulls with ad libitum access to a total mixed ration feeding. The two energy supplements were flattened barley (B) and a mixture (1:1 on dry matter (DM) basis) of flattened barley and barley fibre (BF). These were fed with either rapeseed meal or barley protein so that the crude protein content of rations was 162 g kg (1 DM. Replacing half of the barley grain with barley fibre increased (P B0.01) the average DM intake (9.3 kg d (1 versus 9.9 kg d (1 ), but had no effect on the average live weight gain (1.27 kg d (1 ). There seemed to be only a minor difference between rapeseed meal and barley protein as protein supplements on animal performance.
