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.

Two experiments were conducted to determine the influence of feeding sulfur dioxide (SO2)-treated high-moisture barley (HMB) on the performance of lactating dairy cows and feedlot cattle. High-moisture barley was ensiled or treated with 1% (wt/wt) liquid SO2. In exp. 1, 36 lactating Holstein cows were assigned to three treatments for a 6-wk trial. Diets contained 35% rolled barley on a dry matter (DM) basis and differed only in the type of barley fed: dry barley, ensiled HMB or SO2-treated HMB. While no differences (P > 0.05) were observed in DM intake, milk yield, milk composition, milk taste or odour, cows fed SO2-treated HMB tended to have lower milk yield (21.7 kg d−1) than those fed ensiled (22.6 kg d−1) or dry barley (24.6 kg d−1). In experiment 2, 64 steers were allotted to four dietary treatments: (1) dry barley, (2) ensiled HMB, (3) SO2-treated HMB, and (4) SO2-treated HMB plus sodium bicarbonate. All diets contained 85% barley (DM) and were supplemented with thiamin (5.5 mg kg−1 DM). The results of the feedlot trial were confounded by the feeding of spoiled SO2-treated HMB, primarily between days 29 and 57 of the 96-d trial, at approximately 40% of the diet DM. During the period that spoiled SO2-treated grain was being fed, four steers (two from each treatment) developed polioencephalomalacia. Steers fed SO2-treated HMB (diets 3 and 4), had 10.1% lower DM intake (P < 0.01), 31% lower average daily gain and required 32% more DM per kilogram of gain than steers fed diets 1 or 2 (P < 0.001). Feeding SO2-treated HMB to either dairy or feedlot cattle cannot be recommended at the present time. Key words: Sulfur dioxide, preservative, barley, cattle (dairy, beef)

Abstract Hulless varieties of barley have been developed to improve the digestibility of this small grain. The objective of this project was to determine the feeding value of hulless barley relative to corn in a beef-finishing ration. Angus-cross steers (n = 12) were fed rations that included varying ratios of cracked corn and cracked hulless barley. Steers were stratified by body weight (BW) and allotted to one of four rations: corn, 2:1 ratio of corn to barley, 1:2 ratio of corn to barley, and barley. All treatments included concentrate at 85% and baleage at 15% of total ration dry matter (DM). Rations were fed ad libitum on an individual basis using Calan gates. Feed refusals were measured daily. Steers were weighed and ultrasound 12th rib fat thickness (FT) was measured every 28 d. Steers were harvested at a commercial abattoir when average FT exceeded 0.9 cm. Average daily gain (1.2 kg/d), final BW (653 kg), feed to gain efficiency (10.2:1), and final ultrasound FT (0.94 cm) were not different (P ≥ 0.1486) between treatments. Steer DM intake was lower (P ≤ 0.0496) for those fed corn (9.8 kg/d) compared to those fed barley (12.2 kg/d) or a 1:2 ratio of corn to barley (11.7 kg/d); steer DM intake was similar (P ≥ 0.0640) for those fed a 2:1 ratio of corn to barley compared to those fed the other rations. Finishing ration did not affect hot carcass weight (384 kg; P = 0.7158), carcass FT (1.6 cm; P = 0.9511), ribeye area (87.7 cm^2; P = 0.7184), kidney, pelvic, and heart fat (2.6%; P = 0.3842), and yield grade (3.5; P= 0.8802). Feeding hulless barley compared to corn resulted in similar performance and carcass characteristics when included in beef finishing rations although feed intake was greater when barley exceeded 56% of the ration DM.

In some part of world for intensive production of fattening of lambs, they are fed with high amount of concentrate. However this pattern of feeding often affect negatively of rumen fermentation (Mould et al., 1983). Ionophores act by interrupting transmembrane movement and intracellular equilibrium of ions in certain classes of bacteria and protozoa that inhibit the gastrointestinal tract (McGuffey et al., 2001). In Ruminants, monensin has shown selective inhibition of ruminal bacteria, lactic and methane producers and stimulation of propionate production by 25% (Matabudul et al., 2001). In lambs, monensin improves weight gain and feed conversion ratio (FCR) and depressed the dry matter intake (DMI) (Martini et al., 1996), but lasalocid improve average daily gain (ADG) without depressed the DMI (Swanson et al., 2000). There is limited information about the effect of ionophores on performance of Iranian fattening lambs and particularly no works was done with Arabi lambs. Therefore, the present study was conducted to investigate the effects of feeding monensin and lasalocid on performance and carcass characteristics of fattening Arabi lambs.

In a 55-d backgrounding period, 120 (n = 22) British cross heifers (312 ± 20 kg) received diets containing 55% barley silage, 5% supplement and 0 (n = 24), 20 (n = 24), or 40% (n = 22) wheat distillers’ dried grains with solubles (DDGS). The remainder of the diet was steam-rolled barley. Replacing half (20%) or all (40%) of the barley with DDGS did not affect dry matter intake (DMI) (P = 0.61), average daily gain (ADG) (P = 0.86), or gain:feed (P = 0.94), indicating the energy content of DDGS is similar to that of barley when included in backgrounding diets. During a 133-d finishing period, DDGS were included at 0, 20, 40, or 60% of diet dry matter (DM) or at 60% plus additional calcium, provided as 1% limestone (n = 24). Additional calcium did not (P > 0.1) affect DMI, ADG, or gain:feed. Increasing levels of DDGS linearly increased (P = 0.001) DMI and reduced (P = 0.04) gain:feed and diet NEg content (P = 0.001), but had no effect on ADG (P = 0.20). Feeding 60% DDGS reduced (P < 0.01) DM digestibility as compared with the control. Wheat DDGS has similar feeding value as barley when included at 20% of diet DM, but digestibility and energy content decline with higher levels of inclusion.

Abstract: The objective of this work was to evaluate the performance of young Nellore bulls and of young dual-purpose dairy bulls fed proportions of 'Mulato II' grass silage (400 and 100 g kg-1), in diets with high levels of concentrate, as well as to evaluate the cost of this feed. Sixteen young Nellore bulls and 16 young dairy crossbred bulls were used, with initial average weight of 380.69±10.45 and 376.94±17.16 kg, respectively, and average initial age of 24 months. A completely randomized experimental design was carried out in a 2x2 factorial arrangement. The highest silage proportion caused a 13% increase in dry matter intake (percentage of body weight) and a 19.7% decrease in dry matter digestibility of the diet, but it did not alter the intake of total digestible nutrients, nor the average daily gain or carcass characteristics. Nutrient intake and digestibility, average daily gain, and carcass characteristics (except conformation) did not change due to the genetic group of animals. Feed conversion was 18.3% better in young dairy bulls. In diets with high levels of concentrate, the proportion of 400 g kg-1 of 'Mulato II' grass silage, in comparison with that of 100 g kg-1, does not affect the productive performance, nor the main carcass characteristics of economic interest of confined young bulls, but reduces feeding costs.

Abstract This experiment compared performance and health responses of feedlot cattle receiving a synbiotic supplement (yeast-derived prebiotic + Bacillus subtilis probiotic), which replaced or were fed in conjunction with feed-grade antimicrobials (monensin and tylosin) during a 56-d receiving period. Angus-influenced steers (n = 192) from 4 different sources were transported for 800 km, and arrived on the experimental feedlot on d 0 when shrunk body weight (BW) was recorded. Steers were ranked by source and shrunk BW, and were allocated to 1 of 24 drylot pens. Pens were assigned to receive a free-choice diet containing: 1) monensin and tylosin (RT; 360 mg/steer daily from Rumensin and 90 mg/steer daily from Tylan; Elanco Animal Health, Greenfield, IN), 2) yeast-derived ingredient and B. subtilis probiotic (CC; 18 g/steer daily of Celmanax and 28 g/steer daily of Certillus; Church and Dwight Co., Inc., Princeton, NJ), or 3) monensin and tylosin combined with yeast-derived and B. subtilis ingredients (RTCC) as in RT and CC. Feed intake was greater (P &lt; 0.01) in CC compared with RT and RTCC cattle (7.34, 6.15, 6.22 kg of dry matter/head daily, respectively; SEM = 0.29). Average daily gain tended (P ≤ 0.10) to be greater in CC compared with RT and RTCC cattle (1.23, 1.16, 1.16 kg/d, respectively; SEM = 0.03). Feed efficiency was less in CC compared with RT and RTCC cattle (0.160, 0.173, 0.171 kg/kg, respectively; SEM = 0.003). Incidence of bovine respiratory disease did not differ (P = 0.37) between treatments (25.9, 20.2, and 15.5% for CC, RT, and RTCC, respectively; SEM = 5.2) during the 56-d receiving period. Collectively, replacing RT with CC improved feed intake and BW gain during a 56-d receiving period, despite reducing feed efficiency. Combining RT and CC ingredients, however, did not yield additional productive and health benefits to receiving cattle.

Trial was carried out on 60 suckling lambs of Mis sheep population, divided into three groups. Beside milk, lambs consumed alfalfa hay and iso-protein concentrate mixtures (15% CP) ad libitum. Forage mixture I was of standard composition, whereas mixtures II and III contained 4 and 6% of beef tallow, respectively. Energy value of used mixtures I, II and III was 7,29, 7,71 and 7,94 MJ, respectively. Fattening duration was 60 days. Statistical processing of obtained data was performed using standard mathematical-statistical methods. Lambs on treatments I:II:III realized average daily gain of: 0,280 : 0,303 : 0,277 kg. Conversion of dry matter of diet was: 2,68: 2,58: 2,93 kg; of energy: 19,08 : 18,37 : 20,71 MJ NEM; of protein: 481 : 451: 514 g. Values of the meat yield of warm carcass were: 57,89 : 58,63 : 58,46%. The best production results in regard to gain, and feed conversion were realized by lambs on treatment with 4% of beef tallow in the mixtures.

Abstract Four hundred and thirty-two beef steers (346.3 ± 63.7 kg BW) were used to determine the effects of Zn source on feedlot cattle fed ractopamine hydrochloride. Cattle were blocked in groups of 54 by BW and housed in 48 pens containing 9 steers per pen. Pens within a weight block were randomly assigned to treatments in a 2 x 3 factorial arrangement, with factors being: 1) 0 or 30.1 mg of ractopamine HCl/kg DM fed during the final 29 days on feed; and 2) Zn source: 90 mg of supplemental Zn/kg DM from ZnSO4; Zn sulfate (67%) + Zn methionine (33%); and Zn from Zn hydroxychloride, fed through the entire feeding period. Cattle were fed a high concentrate finishing diet for 154 d and slaughtered at a commercial abattoir. Average daily gain, DMI, feed efficiency and carcass characteristics were determined after slaughter. Zinc source had no impact on live animal performance. Cattle fed ractopamine HCl had greater (P &lt; 0.01) final BW, greater (P &lt; 0.001) ADG, improved (P &lt; 0.001) G:F, heavier (P &lt; 0.01) HCW, and larger (P &lt; 0.05) longissimus muscle compared to non-ractopamine supplemented steers. There was a Zn source by ractopamine interaction (P &lt; 0.01) for dressing percentage. Cattle receiving ractopamine HCl with Zn hydroxychloride had a greater dressing percentage (P &lt; 0.05) when compared to ractopamine HCl cattle fed other Zn sources. Cattle receiving ractopamine HCl with Zn sulfate had a lesser dressing percentage (P &lt; 0.05) when compared to ractopamine HCl cattle fed other Zn sources. Additional Zn source by ractopamine HCl interactions were not significant. These data indicate that Zn source has minimal impacts on feedlot steer performance and carcass characteristics when supplemented to cattle receiving 0.0 or 30.1 mg of ractopamine HCl/kg DM.

A study was conducted to examine how lupin grains (LUPs) feeding affected nutritional intake, digestibility, growth, and carcass characteristics in kids. A total of 24 growing black kids (initial body weight (BW) = 16.4 ± 0.49 kg) were allocated to one of three diets at random. Lupin was included in the diet at a rate of 0 (control; CON), 100 (LUP100), or 200 g/kg (LUP200) of total dry matter (DM). The trial lasted for 91 days divided into 7 and 84 days to be used for adaptation and data collection, respectively. Feed intake was evaluated daily throughout the study. At the commencement and the end of the study, each kid’s body weight was measured to determine its average daily gain (ADG). On day 70, 5 kids were chosen at random from each group to investigate nutrient in vivo digestibility and N balance. At the end of the study, all of the kids were slaughtered to examine carcass features. Nutrient intakes (neutral detergent fiber, acid detergent fiber, and ether extract) were higher (p ≤ 0.01) in LUP-containing diets than in the CON diet. The average daily gain was greater (p ≤ 0.03) in diets containing lupin grains than in the CON diet. Cost of gain ($US/kg growth) was lower (p = 0.004) in kids fed diets containing lupin than the CON diet. Dry matter and CP digestibility rates were greater (p ≤ 0.03) in lupin diets. Retained N was higher (p = 0.04) in lupin-containing diets than in the CON diet. Cold carcass weight was higher (p < 0.05) for kids consuming the LUP100 diet than the CON diet. In lupin diets, carcass cut weights were higher (p < 0.05). Results of the current study indicate that feeding black kids diets containing lupin grains at 100 or 200 g/kg DM basis is cost effective and would increase profitability.
