A total of 120 steers were fed either barley silage (BS) or triticale silage (TS) combined with barley (B) or high-moisture barley (HMB) grain, as a total mixed ration in a 2 × 2 factorial design with three replications. The barley and triticale yields were 9.8 and 8.7 t ha−1, respectively. No differences (P > 0.05) in weight, average daily gain, dry matter intake or feed efficiency were observed for treatments or interactions. TS can be used to replace BS at moderate levels in growing steer rations containing barley grain. Key words: Barley, triticale, silage, steers, performance

Supplementing a control diet of ground alfalfa (CON) with monensin (MON), chlortetracycline (CTC) or tylosin (TYL) did not affect (P < 0.05) dry matter intake or average daily gain of market lambs. Feed efficiency with CTC was less than with the unsupplemented control (CON) (6.22 vs. 5.68) (P < 0.05). Mean digestibilities of dry matter, acid detergent fiber and neutral detergent fiber were lower (P < 0.05) with all antibiotic treatments than the CON diet. Relative to CON, nitrogen digestibility was increased with MON (66.3 vs. 70.9%) while that of energy was reduced with TYL (P < 0.05). Rumen ammonia and acetic, propionic and butyric acid concentrations were not influenced by any of the treatments. MON, CTC and TYL were not effective supplements for lambs fed alfalfa finishing diets. Key words: lamb, chlortetracycline, monensin, tylosin, alfalfa hay, digestibility

Barley of three different volume-weights (VW) (light, 47.8; medium, 55.6; heavy, 66.6 kg hL−1) was subjected to two processing treatments (DR, dry rolled; SF, steam flaked) and fed to 192 yearling steers (avg. body weight 332 kg) at a level of 85% of the dietary dry matter (DM) in combination with barley silage (10.75% of DM) and mineral-vitamin premix (4.25% of DM) during the finishing period. No significant two- and three-way interactions were observed for any of the traits studied. Average daily gain (ADG) of cattle fed SF and DR diets was similar (P > 0.05) except during the first 27 d of the trial in which the SF steers gained 9.4% faster (P < 0.05) than the DR steers. Dry matter intake (DMI) of steers fed SF barley tended to be higher (P < 0.10) in period one and in period three than for those fed DR barley but was similar for both processing groups in periods two and four and overall. Dry matter consumed per unit of liveweight gain (DM/G) was similar for the two processing treatments during all periods and overall although it tended (P < 0.10) to be lower for the DR steers during period two. Volume-weight had no effect (P > 0.05) on ADG or DMI. Overall, DM/G decreased (P < 0.01) an average 1.2% for each unit (kg hL−1 increase in VW from 47.8 to 55.6 kg hL−1. DM/G was similar for cattle fed medium and heavy barley. Large steers (avg. bodyweight 350 kg) gained 17.5% faster (P < 0.01), consumed 12% more (P < 0.01) dry matter and required 4.9% less (P < 0.01) DM per unit of gain than small steers (avg. bodyweight 314 kg). Steam flaking of the barley produced carcasses with 0.14 cm more (P < 0.05) grade fat and resulted in 31% fewer (P < 0.05) liver condemnations due to abscesses than dry rolling but did not influence the other carcass quality perameters. Medium VW barley resulted in lower (P < 0.05) grade fat than either light or heavy barley, which produced similar grade fat measurements. Large steers, marketed at an average liveweight that was 14.5 kg heavier (P < 0.01) than the small steers, had lower (P < 0.05) marbling scores than the small steers.

Abstract The aim of this trial was to evaluate the effect of encapsulated calcium ammonium nitrate as a partial substitute for soybean meals in the concentrate dry matter intake, average daily gain and feed efficiency of Nellore young bulls under grazing conditions, during the dry season. Sixty-four weaned Nellore (initial BW = 177.46±3.77 kg and 9 mo old) were used in a completely randomized assay. The study lasted 84 days on the dry season. Animals were allotted into 16 paddocks of 1.0 ha each of Urochloa brizantha, randomly assigned into one of two treatments: (CTL) supplement with 25% CP, without nitrate inclusion and; (ENP): supplement with 25% CP, with a inclusion of 50 g of encapsulated calcium ammonium nitrate to each 100 kg of body weight. Animals were fed with concentrate at 1.0% of body weight. Concentrate offered was monitored daily as well as his refusals were collected and weighed to determine daily concentrate dry matter intake (DMI) and feed efficiency (F:G). Animals were weighed every 28 d for calculating average daily gain (ADG). Data were analyzed as a completely randomized design, using ANOVA (α = 0.05). No effects of treatments (P &gt; 0.3487) were observed for final BW (246.69 kg). The same for concentrate dry matter intake (P &gt; 0.0550). Animals consumed 2.34 kg of supplement per day. The average daily gain (0.832 kg, P &gt; 0.2649) and feed efficiency (0.356 kg, P &gt; 0.7315) were not affected by the inclusion of nitrate. The inclusion of encapsulated calcium ammonium nitrate in supplement to Nellore young bulls under grazing conditions during the growing phase did not affect the performance.

Three factorial experiments were conducted to determine the relative feeding value of dry barley (DB) and high-moisture barley (HMB), and to evaluate the influence of method of ensiling (Pit vs. Harvestore® (HAV) silo), source of roughage (hay vs. silage), and level of concentrate (90 vs. 75%) on the performance and carcass characteristics of feedlot cattle. In exp. 1, 252 steers (initial wt 357 kg) were assigned on the basis of weight to six treatments (two pens × 21 animals per pen). A mixed diet consisting of 85.2% barley grain (dry matter (DM) basis) was offered free choice. The barley portion of the ration consisted of either 0, 25, 50, 75 or 100% DB with the balance being HMB from a pit silo. The sixth treatment consisted of feeding 100% HMB for the first 57 d and 100% DB for the remainder of the trial. Overall average daily gain (ADG) for steers fed 100% DB (1.70 kg d−1) was significantly higher than observed for animals fed 100, 75 or 50% HMB (1.46, 1.49 and 1.56 kg d−1, respectively). The kg of feed DM required per kg gain (FC) varied between 5.76 and 7.13 and was not (P > 0.05) influenced by treatment. No differences (P > 0.05) were observed in carcass characteristics. In exp. 2, 360 steers (initial wt 340 kg) were allotted on the basis of weight to six treatments designed to evaluate the effect of source (Pit vs. HAV) and level of HMB, in diets containing 10.2% silage, on animal performance. Overall ADG (1.11 – 1.17 kg d−1), FC (6.66 – 7.01) and carcass characteristics were similar (P > 0.05) for animals fed Pit HMB, HAV HMB and DB. In exp. 3, 264 weanling calves (initial wt 216 kg) were allotted on the basis of weight to six treatments which differed in type of barley (HMB vs. DB), source of roughage (hay vs. silage) and level of concentrate (75 vs. 90%; DM basis). The feeding period was 127 d. Daily gains varied between 0.78 and 0.91 kg d−1 and FC ranged from 6.40 to 7.10 and were not influenced (P > 0.05) by source of barley or source or level of roughage. While animals fed DB had significantly higher ADG than those fed HMB in exp. 1, the overall results from the three experiments indicate that on a DM basis HMB has similar feeding value to DB, and that there is no major difference between Pit and HAV-stored HMB for feedlot cattle.

A new oat cultivar, CDC SO-I, with a low lignin hull and high oil groat was evaluated in backgrounding diets for steer calves, with an emphasis on the requirement for processing. Average daily gain was not different (P > 0.05) between calves fed rolled barley, rolled oat, or whole oat diets. Dry matter intake of cattle fed the rolled oat diet was greater (P = 0.04) than that of cattle fed the rolled barley or whole oat diets. Feed:gain was not affected (P = 0.13) by treatment. Results indicate the CDC SO-I oat does not require processing (i.e., rolling), and can replace barley in backgrounding diets with no negative effect on animal performance.

This study was conducted to determine optimum test duration for measuring performance, feed intake and feed efficiency. Sixty young Nellore bulls were submitted to feeding performance test and fed in individual pens to determine feed intake and performance over 112 days. Body weight was determined every 28 days, after fasting of water and feed for 16 hours. Changes in variance, relative variance and Pearson and Spearman correlations among data from shortened test periods (28, 56 and 84 days) and full test period (112 days) were used to determine optimum test duration. Test duration for average daily gain, dry matter intake, feed:gain ratio and residual feed intake could be shortened to 84, 28, 84 and 84 days, respectively, without reducing significantly the reliability of measurements for animals fed in individual pens.

Daily Gain

Steers fed triticale adapted to the diet more slowly than those fed barley, resulting in reduced overall feed intake (9.4 vs. 10.5 kg d−1, P = 0.08) and average daily gain (ADG) (1.3 vs. 1.5 kg d−1, P = 0.08). No difference was detected in feed:gain ratio (7.1 vs. 6.8, P = 0.65). The reduced ADG in the triticale-fed steers may be due to reduced feed intake and the longer time required to adapt.

The study was conducted for 48 days to assess the use of kaun as a source of mineral for Hest African Dwarf sheep. The study was in two parts. Experiment l involved the use of milled kaun mixed with formulated concentrate consisting of wheat offal (50%), palm kernel cake (25%) and dried brewer's grains (25%). Experiment II was the use of dissolved kaun administered to the animals in form / drenching. Each group of animals in experiment 1 was allocated to experimental diet containing milled kaun (0.00, 0.14, 0.28, 0.45 and 0.56g/kg body weight/ram. day) and to kaun solution (0,2,4,6 and 8g: 10ml of water/ram/day) in experiment II. In Experiment I, significant (P<0.05) effects of the diets were observed on average daily gain, dry matter intake and water consumption. The rams on D3 significantly (P<0.05) performed better in daily gain, dry matter intake and feed efficiency than those on other dietary treatment. Water consumption increased with increasing level of kaun in the diets. Animals on D5 had the highest water consumption. No significant (P>0.05) effects of the diets were observed on faecal and urinary mineral outputs of the rams fed kaun supplemented diet. The concentration of these minerals was higher at the end of the experiment than at the beginning thereby giving positive balance. Significant (P<0.05) negative mineral balance was noticed between serum mineral before and after the experiment. This could suggest that mineral utilization was encouraged by kaun inclusion in the concentrate feed. In Experiment II, there were significant (P<0.05) effects of the test diets on average daily gain, dry matter intake and water consumption. Diet 4 (g/10ml of water/ram/day) and D5 (8g:10ml of water/ram/day) performed better with an average daily gain of 100g/d and 92.9g/d; dry matter intake, 70g W0.7kg and 66g/W0.75kg; feed efficiency 0.700 and 0.710, respectively. Water consumption also increased with increase in the concentration of kaun solution but water consumption in treatment groups was lower than in the control (0.10L/kg body weight). The results of this study suggest that 0.28g kaun kg body weight ram/d) promoted better performance in experiment / while 6g kaun/10ml of water, or 8g kaun 10ml of water/ram/d promoted better performance in experiment II. These levels of kaun as a source of mineral in sheep production are therefore recommended for optimum performance.
