Twenty steers fed corn silage supplemented with 0.5% urea gained 0.71 kg/day compared with 0.30 for 20 steers fed grass silage supplemented with 9% beet pulp (P < 0.05). Steers fed corn silage had less rib lean (53.0%) and intensive carcass fat color (2.9) than grass-silage-fed steers (56.3% and 3.6, respectively) (P < 0.05). All steers, except four in the grass-silage-fed group, graded either A1 or A2. Key words: Silage finishing, steers, growth, carcass fat color, carcass grade

Weight Groups

Sixty small-framed yearling Hereford and Hereford cross steers initially averaging 268 kg were reared on pasture from May to October, divided into two (30 each) approximately equal weight groups and placed in a feedlot. The steers were serially slaughtered in groups of 10 (five heaviest from each treatment) after 0, 35, 70, 98, 126 or 154 days of feedlot finishing on either grass or corn silage supplemented with 0.9–2.3 kg-head−1∙day−1 of a mixed grain ration containing 5% molasses. Average gains on pasture were 0.80, 0.75 and 0.54 kg/day for the consecutive 59, 48 and 61 day periods between 9 May and 24 Oct. Steers finished on corn silage gained significantly faster (P < 0.05) and had significantly more dissectable rib fat when slaughtered (0.82 kg/day; 27.6%) than steers finished on grass silage (0.51 kg/day; 24.6%). Six of the 10 steers slaughtered off pasture graded B1 or C1 while one of the feedlot steers graded B1 and the remaining 53 graded A1 or A2. The subjective carcass fat color score of the steers slaughtered off pasture averaged 4.7 which was significantly greater than the fat color of the feedlot finished steers (3.0–3.6). The corn silage steers had a color rating of 3.4 while the grass silage steers rated 3.7. The results of this experiment indicate that yearling steers reared on pasture and finished between 35 and 70 days on grass or corn silage with low concentrate supplementation will produce acceptable carcasses in terms of grade and subjective fat color score. Key words: Growth, carcass characteristics, steers, pasture, silage

Two, experiments were conducted with growing and finishing steers to determine the performance response to feeding avoparcin with or without progesterone-estradiol (Synovex-S) implants. In exp. 1, 96 crossbred yearling steers were fed diets containing 40% hay crop silage (DM basis) for 168 days. Avoparcin increased (P < 0.05) weight gains (16%) and feed efficiency (16%). Initial Synovex-S implants increased (P < 0.05) weight gain (14%) and feed efficiency (11%). Reimplanting at 112 days tended to further improve (P > 0.05) rate of gain and feed efficiency over initial implanting. In exp. 2, 80 Hereford yearling steers were fed diets containing only 19% corn silage (DM basis) for 98 days. Avoparcin had no effect on weight gain but improved (P > 0.05) feed efficiency (11%). Synovex improved (P < 0.05) weight gain (17%) and feed efficiency (11%). In both experiments treatments produced no effects on carcass measurements except for an increase in warm carcass weight. Also, in both experiments the effects of avoparcin and Synovex on feed efficiency were fully additive. Key words: Growth promotants, implants, feed additives, steers

This study aimed to evaluate the effect of different amounts of incubated samples on the kinetic parameters of in vitro fermentation of roughage and concentrated food used for feeding ruminants. Samples were prepared using 200, 300, 400, and 500 mg of air-dried roughage and concentrated sample, ground to 1 mm, and placed in 120 mL glass flasks. Next, inoculum and McDougal solution were added, and the readings were obtained using a semi-automated pressure transducer up to 96 h after the beginning of the incubations. Gas production of the non-fibrous fraction increased linearly (P < 0.05) for sugarcane, Marandu grass silage, corn silage, dried corn distillers’ grains with solubles, dried brewer’s yeast, bean residue, wet brewer’s grains, sunflower meal, and Jatropha meal; quadratically (P < 0.05) for Napier grass silage and cottonseed meal; and cubically (P < 0.05) for castor meal and soybean meal. The degradation rate of the non-fibrous fraction reduced linearly (P < 0.05) for sugarcane, Napier grass silage, and castor meal; quadratically (P < 0.05) for Marandu grass silage; and cubically (P < 0.05) for corn silage, soybean meal, dried corn distillers’ grains with solubles, bean residue, and cottonseed meal. Gas production of the fibrous fraction increased linearly (P < 0.05) for Napier grass silage, Marandu grass silage, corn silage, dried corn distillers’ grains with solubles, bean residue, wet brewer’s grain, cottonseed meal, and sunflower meal; quadratically ( < 0.05) for Jatropha meal; and cubically (P < 0.05) for sugarcane, castor meal, and soybean meal. The degradation rate of the fibrous fraction increased linearly (P < 0.05) for Napier grass silage, dried corn distillers’ grains with solubles, dried brewer’s yeast, wet brewer’s grains; quadratically (P < 0.05) for corn silage and castor meal; and cubically (P < 0.05) for sugarcane, Marandu grass silage, and bean residue. The lag time reduced linearly (P < 0.05) for castor meal and dried corn distillers’ grains with solubles; quadratically (P < 0.05) for Napier grass silage; and cubically (P < 0.05) for sugarcane, Marandu grass silage, corn silage, soybean meal, bean residue, cottonseed meal, sunflower meal, and Jatropha meal. Thus, our findings suggest that the kinetic parameters of in vitro fermentation were affected as a function of the amount of incubated sample.

Different Levels

Over a 2-yr period, 44 bulls and 44 implanted steers of Hereford × Shorthorn breeding were fed, from weaning to slaughter, diets of grass silage with 0, 0.45, 0.9 or 1.35 kg barley dry matter (DM)/100 kg liveweight. Each animal was slaughtered when it had 8 mm of fat over the loin as determined by ultrasound measurement. As the level of barley in the diet increased the rate of gain increased (P < 0.01), as did DM intake (P < 0.05) while feed required per kilogram gained and days on feed decreased. Bulls and steers responded in a similar manner to the different diets. Bulls gained faster (P < 0.01) on similar intakes of DM with the result that feed required for kilogram gain was less for bulls (P < 0.05). There was no difference (P > 0.05) in days to market for bulls and steers. There was no consistent effect of diet on carcass characteristics. However, castration resulted in lighter (P < 0.01) slaughter and carcass weights as well as a smaller (P < 0.01) rib eye area. Key words: Cattle, castration, diet, growth, carcass

Beet Pulp

Due to its slower rate of rumen degradation, molassed sugar beet pulp (MBP) is considered to result in a higher pH in rumen fluid wnen compared with cereals and to be of benefit in diets where maximum fibre digestion is desired (Fahmy et al., 1984). Sodium hydroxide-treatment of MBP, by increasing feed pH may increase the value of MBP still further in these situations. The most common method of processing whole cereal grains is dry rolling. Sodium hydroxide pre-treatment has also been shown to increase the digestibility of whole cereal grains close to thai achieved by dry rolling (Orskov, 1979). Little information is available on the relative effects on rumen fermentation of both processing methods. The objectives of this study were to (1) determine the effects of treating MBP with NaOH and (2) compare the effects of rolfing (R) and S as processing methods for barley and wheat, on rumen fermentation and dry matter (DM) degradability (DMD) in steers offered grass silage.

Copper (Cu) depleted steers were used to compare copper sulfate and copper proteinate as Cu sources for cattle consuming high molybdenum diets. Two experiments utilizing corn silage and barley concentrate diets with 10 mg added Mo kg−1 DM were undertaken. Experiment A was a 105-d study in which an 83:17 ratio of silage to concentrate was fed, whereas, experiment B was an 84-d study comparing the same Cu treatments for cattle fed a 26:74 (Low) or a 64:36 (High) ratio of silage to concentrate. Cu treatments for both experiments were: no supplemental Cu (0Cu); a dietary supplement of 10 mg Cu kg−1 DM added as copper sulfate (CuSO); and a dietary supplement of 10 mg Cu kg−1 DM added as copper proteinate (CuPro). Both Cu supplements improved (P < 0.05) concentrations of Cu in plasma for both experiments and improved (P < 0.05) concentration of Cu in liver for experiment B. Copper supplementation (P < 0.05) reduced plasma Mo concentrations in experiment A relative to animals receiving no supplemental Cu. Both Cu sources resulted in reduced rumen fluid soluble Mo concentrations. Steers in experiment A had lower initial liver and plasma Cu concentrations than was observed for experiment B. Average daily gains for steers consuming CuPro were 16.8% greater (P < 0.05) than for 0Cu with CuSO being intermediate for experiment A. Results indicate that the bioavailability of Cu from Cu proteinate is similar to that of copper sulfate in-Cu depleted steers consuming diets containing excess Mo.
