Abstract One hundred twenty-eight Angus-cross steers (492 ± 29 kg) were utilized in a 2 × 4 factorial to determine the effects of dietary Zn within implant strategy on performance, carcass characteristics, and Zn status. Factors included Zn supplemented at 0, 30, 100, or 150 mg/kg dry matter ([DM]; Zn0, Zn30, Zn100, Zn150, respectively) from ZnSO4 and implant administered on d 0 as no implant (NoIMP) or Component TE-200 (TE-200; Elanco, Greenfield, IN). Cattle were stratified by bodyweight (BW) to GrowSafe equipped pens of 5 or 6 steers and assigned to pen-wide treatments (experimental unit of steer; n = 16/treatment). Steers were weighed on d -1, 0, 18, and 59 with blood collected on -1, 18, and 40. Via Proc Mixed of SAS, linear and quadratic effects of Zn within implant treatments and assessment of NoIMP vs. TE-200 were tested for performance, carcass characteristics, and plasma data, with initial value covariates. Plasma Zn concentrations on d 18 and 40 linearly increased within NoIMP and TE-200 (P ≤ 0.03) and were lesser for TE-200 than NoIMP on d 18 (P = 0.001). Zinc linearly increased (P ≤ 0.002) d 18 BW and d 0–18 average daily gain (ADG). Within TE-200, Zn increased dressing percentage (P = 0.01) and tended to increase hot carcass weight (P = 0.09) linearly. Carcass-adjusted final BW and overall ADG tended to increase (P = 0.10) linearly within TE-200, with no Zn effects within NoIMP (P ≥ 0.18). Implanting increased carcass-adjusted final BW 13 kg over NoIMP (P < 0.0001). Overall feed efficiency quadratically increased within NoIMP (P = 0.01) peaking at Zn100 with no observed Zn effects within NoIMP or TE-200 for overall DM intake (P ≥ 0.15). These data suggest implant-induced growth in steers may require dietary Zn above current national recommendations.

Abstract A total of 288 pigs (Line 600 241, DNA, Columbus, NE; initially 41.6 kg) were used in an 82-d trial to determine if replacing conventional yellow dent corn with high amylase corn (Enogen®, Syngenta Seeds, LLC, Downers Grove, IL) in diets with or without distillers dried grains with solubles (DDGS) influences growth performance and carcass characteristics. Diets were arranged in a 2 × 2 factorial with 2 corn sources (yellow dent or high amylase) and 2 levels of DDGS (0 or 25%). Experimental diets were fed in meal form in 3 phases: d 0 to 29, 29 to 47, and 47 to 82. There were 9 pens/treatment each containing an equal number of barrows and gilts. Pigs were weighed approximately every 2 wk and at the beginning of each phase. On d 82, pigs were transported to a commercial packing plant for processing and carcass data collection. Data were analyzed using PROC GLIMMIX procedure of SAS with pen as the experimental unit. There were no interactions (P > 0.05) between corn source and DDGS inclusion for overall performance or carcass characteristics. Overall, average daily gain (ADG) was marginally greater (P < 0.089) for pigs fed high amylase than yellow dent corn with no evidence (P > 0.196) for difference in feed intake, feed efficiency (G/F), hot carcass weight (HCW), or other carcass traits. Addition of DDGS resulted in decreased (P < 0.037) overall ADG and G/F. Pigs fed DDGS had marginally lower (P < 0.071) HCW, less (P < 0.050) backfat, greater (P < 0.026) loin depth, and greater (P < 0.020) percentage lean and iodine values. In summary, high amylase corn tended to improve overall ADG; however, feed efficiency and carcass characteristics were unchanged between corn sources. Consistent with previous research, addition of DDGS decreased ADG and increased IV.

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 < 0.01) final BW, greater (P < 0.001) ADG, improved (P < 0.001) G:F, heavier (P < 0.01) HCW, and larger (P < 0.05) longissimus muscle compared to non-ractopamine supplemented steers. There was a Zn source by ractopamine interaction (P < 0.01) for dressing percentage. Cattle receiving ractopamine HCl with Zn hydroxychloride had a greater dressing percentage (P < 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 < 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.

The study investigated the effects of re-alimenting dietary protein or energy on growth, carcass characteristics and meat eating quality parameters of sheep. Twenty-seven intact rams (~9 months; 11.3 ± 0.5 kg) were randomly divided into three groups. Each group was fed a maintenance diet (MT) containing, on dry matter (DM) basis, 105 g/kg crude protein (CP) and 8.4 MJ/kg DM metabolizable energy (ME) for 30 days. Thereafter, they were continually fed the same MT or re-alimented with a high protein diet (HP) containing 169 g/kg DM CP and 9.3 MJ/kg ME or a high energy diet (HE) containing 123 g/kg DM CP and 10.6 MJ/kg ME for an additional 30 days to determine the effects of re-alimentation of protein or energy on their growth performance and carcass characteristics. During the initial 30-day period, DM intake (DMI) and growth performance were similar among the three groups. However, upon re-alimentation, average daily gain (ADG) and feed efficiency of sheep re-alimented with HP were greater than those maintained continually on MT or re-alimented with HE. Sheep on HP had higher feed efficiency, ADG and heavier carcasses than those fed MT or re-alimented with HE during the whole 60-day period. Growth of most viscera was less responsive to the restriction-re-alimentation feeding regimen except for the weights of the lungs, heart and intestines. Meat from sheep re-alimented with HE had a more intense ‘sheepy’ flavour than those fed MT or re-alimented with HP, but juiciness and tenderness were not affected. The higher ADG of sheep re-alimented with protein may be related more to enhanced efficiency of feed utilization than to higher DMI.Keywords: average daily gain, feed restriction, nutrient utilization efficiency, visceral organs

Abstract Ractopamine hydrochloride (RAC) is a β-adrenergic agonist approved for feeding during the last 28 to 42 d prior to cattle slaughter to improve feedlot performance and carcass characteristics. Three thousand crossbred yearling steers (527 ± 2.4 kg; AVG ± SD) were used in two periods to evaluate the effects of various RAC withdrawal times on feedlot performance, health, and carcass characteristics. In Period 1, 6 blocks of 30 pens totaling 1,500 steers were utilized, which was repeated for Period 2. In a randomized complete block design, cattle were assigned to 1 of 5 treatments consisting of 1) No RAC fed (CON), 2) 12-h RAC withdrawal (12-hRAC), 3) 2-d RAC withdrawal (2-dRAC), 4) 4-d RAC withdrawal (4-dRAC), and 5) 7-d RAC withdrawal (7-dRAC). Cattle were fed for a total of 62 d, and applicable treatments were supplemented with 30.0 ppm (dry matter basis) of RAC (average dose = 322 mg per steer per day) for 33 d at the end of the feeding period, corresponding to their respective withdrawal times. Initial body weight (BW) displayed a quadratic curve, with 2-dRAC and 4-dRAC withdrawal periods having the greatest BW. Accordingly, dry matter intake (DMI) responded quadratically (P = 0.034), with 2-dRAC and 4-dRAC treatments demonstrating the greatest DMI. No significant treatment differences (P ≥ 0.641) were observed in final live BW, average daily gain (ADG), or feed efficiency. Alternatively, when using a common dressing percentage to calculate live BW, cattle on RAC treatments exhibited 7.6 kg additional live BW (P &lt; 0.001) compared to CON cattle. Furthermore, carcass-adjusted ADG and feed efficiency did not differ (P &gt; 0.10) between RAC treatments but were improved compared to the CON treatment (P ≤ 0.002). Hot carcass weight (HCW) was on average 4.9 kg greater (P &lt; 0.001) for RAC treatments vs. CON, and no differences were detected (P &gt; 0.10) among RAC treatments. Within RAC treatments, carcass cutability responded quadratically (P ≤ 0.005) to withdrawal period, with the 2-dRAC and 4-dRAC treatments containing more Yield Grade 4 and 5 and fewer Yield Grade 1 and 2 carcasses than the other RAC treatments. On the basis of the results of this experiment, feeding RAC improves dressing percentage, HCW, and carcass-adjusted BW, ADG, and feed efficiency. Furthermore, extending the RAC withdrawal period to 7 d does not have a significant impact on cattle performance or health and has minimal effects on carcass characteristics.

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.

Abstract The objectives of the study were to determine the effect of steroidal implants on growth performance, carcass characteristics, and estradiol-17β (E2) concentrations in the blood and longissimus muscle of Holstein steers fed a grain-based diet. Seventy Holstein steers (average initial BW = 275 ± 6.4 kg, 10 to 12 mo of age) were assigned to treatments: (i) implanted with 80 mg of trenbolone acetate (TBA) and 16 mg of E2 (Component TE-IS with Tylan; Elanco Animal Health, Greenfield, IN) at the start of the trial (day 0), and reimplanted with 120 mg of TBA and 24 mg of E2 (Component TE-S with Tylan; Elanco Animal Health) on day 84 of the experiment; or (ii) no implant. Implanted Holstein steers were heavier (P ≤ 0.01) than nonimplanted Holstein steers in the middle (day 84) and at the end of the experiment (day 186). Implanting Holstein steers increased (P &lt; 0.01) average daily gain (ADG) and dry matter intake (DMI) without affecting gain-to-feed ratio compared with nonimplanted animals. Carcasses from implanted Holstein steers had greater (P &lt; 0.01) hot carcass weight (HCW) and longissimus muscle (LM) area than carcasses from nonimplanted steers. Implanting did not affect (P ≥ 0.21) other carcass characteristics. There was an increase (P = 0.03) of 1.3 pg of E2/g of muscle in implanted Holstein steers compared with that from nonimplanted Holstein steers. There was an implant × day interaction (P &lt; 0.01) in serum E2 concentrations. Serum E2 concentrations were not altered in nonimplanted Holstein steers, whereas E2 concentration increased (P &lt; 0.01) after steers were implanted, regardless of implant characteristics. Serum E2 peaked at 28 days after the first implant and then rapidly declined after day 56. In summary, steroidal implants administered on days 0 and 84 increased DMI, ADG, HCW, and LM area in Holstein steers compared with nonimplanted steers due to increased serum E2 concentrations. However, these changes did not improve feed efficiency or other carcass characteristics.

This study evaluated food intake and productive performance of crossbred (½ Santa Inês x ½ dorper) lambs supplemented with different levels of faveleira (Cnidoscolus quercifolius Pohl) fodder salt. Thirty male sheep fed tifton grass hay, water, and faveleira fodder salt were randomly allocated into five treatments with six replicates each. The treatments consisted of diets with different inclusion levels of faveleira hay in the fodder salt composition: Treatment 1 (1% mineral salt + 99% faveleira hay), Treatment 2 (3% mineral salt + 97% faveleira hay), Treatment 3 (5% mineral salt + 95% faveleira hay), Treatment 4 (7% mineral salt + 93% faveleira hay), and Treatment 5 (Control - 100% mineral salt). Intake of dry matter, tifton hay and water, average daily gain, feed conversion, and feed efficiency were not affected by fodder salt supplementation (P > 0.05). There was a significant difference (P < 0.05) in fodder salt intake between Treatments 4 and 5, and daily intake was higher in animals submitted to Treatment 4 (61.0 g day-1). Mineral salt intake increased significantly with increasing mineral salt levels in the diet. However, no significant difference was observed in average daily gain across treatments, indicating that faveleira hay, even in small quantities, and tifton hay were able to meet the nutritional requirements of animals to support a good average daily gain. The inclusion of up to 99% faveleira hay in fodder salt formulations did not affect voluntary intake of forage, water and dry matter, average daily gain, feed conversion, and feed efficiency. Lambs supplemented with faveleira fodder salt had average daily gains within the optimal range for slaughter and high feed conversion and feed efficiency values. Faveleira was shown to be an effective supplementary feed alternative in sheep.

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.
