Beef heifers of 232 and 205 kg average beginning weight, fed individually in a barn in two separate trials, were assigned at random to the following treatments: (A) basic barley–hay ration containing 3–1 ppm Cu and 25–32 ppm Zn; (B) basic ration supplemented to 11–12 ppm Cu; (C) basic ration supplemented to 63–66 ppm Zn. The Cu-supplemented ration resulted in an increased amount of Cu in the liver (P < 0.01). The Zn-supplemented ration resulted in a decreased amount of Cu in the liver in trial 1 (P < 0.05) but did not affect the level of Zn either in the liver or in the hair. No difference was found in average daily gain, feed consumption, efficiency of gain, or dressing percent of the heifers. It was shown that under a full-feed regime for 134 and 151 days, young animals (heifers) with Cu levels in the liver of 100 ppm or more on a dry weight basis can maintain normal metabolic balance when their ration is less than 4 ppm Cu and 33 ppm Zn. Barley and forage grown on Grey Wooded soil of the Peace River area, even though analytically low in Cu and Zn, are sufficient for heifers on full feed. In a third trial, beef steers were fed for 112 days on corn silage fortified with urea. Copper glycinate injections showed no effect on gain, although final concentrations of Cu in the liver were increased from 28 to 133 ppm on a dry weight basis. The corn silage contained 7 ppm Cu and had a Cu/Mo ratio of 6:6. Copper supplementation of corn silage rations is not warranted with this level of copper and a favorable Cu/Mo ratio.

Forty-eight Cu-depleted beef steers were used in a 105-d growing trial to compare four methods of Cu supplementation. Corn silage-barley concentrate diets were supplemented to contain 10 mg kg−1 dry matter (DM) Mo, and 1.3 (low S) or 3.7 (high S) g kg−1 total S. Copper treatments within low and high S diets were: (1) no supplemental Cu (0Cu); (2) a dietary supplement of 10 mg kg−1 DM Cu in the complete feed, added as CuSO4∙5H2O to the concentrate (CuSO4); (3) 20 g copper oxide needles (CuON) orally dosed on day 0; and (4) injectable Cu (ICu) on day 0. Although average daily gain was not different (P > 0.05) among Cu treatments, DM intake was lower (P < 0.05) with CuSO4 and CuON than with 0Cu or ICu. Feed efficiency (FE; feed:gain ratio) was better (P < 0.05) with CuSO4 (FE = 5.60) than 0Cu (FE = 6.88), while CuON (FE = 6.04) and ICu (FE = 6.16) FE were intermediate to 0Cu and CuSO4. Increasing dietary S from 1.3 to 3.7 mg kg−1 DM resulted in lower (P < 0.01) concentrations of Cu and Mo in liver and plasma, and plasma ceruloplasmin activity. An improvement of FE with CuSO4 was related to increased Cu and lower Mo concentrations in the plasma and liver of steers. With ICu there was some indication of an improvement of Cu status. With CuON, measured parameters were indicative of a metabolic Cu insufficiency, but with a lower concentration of Mo in plasma. At the levels of supplementation used in this trial, CuSO4 was a better Cu supplement than CuON or ICu for cattle consuming diets containing excess Mo or Mo plus S.

An economics experiment to study the values of Income over Feed Cost at various market prices of fattening sheep has been done at Sheep Experimental House of The Faculty of Animal Husbandry, UniversitasPadjadjaran. About 63 heads of Garut growing lambs were fattened for 90 days and fed by corn silage and concentrate. Feed consumption and average daily gain (ADG) were measured and Income over Feed Cost was analyzed at different selling prices: 40,000 IDR/kg live weight at general market, 60,000 IDR/ kg live weight at Aqiqah Market, and 80,000 IDR/kg live weight at Qurban Market. The result showed that ADG of lambs was 122 g/head/day resulting in selling prices of 4,882 IDR/head/day for general market, 7,323 IDR/head/day for Aqiqah market, and 9,764 IDR/head/day for Qurban market. If average feed cost was 3,508 IDR/head/day, its Income over Feed Cost was 1.374 IDR/head/day for general market, 3,825 IDR/head/day for Aqiqah market, and 6,256 IDR/head/day for Qurban market. At non-feed cost of 1,921 IDR, there was a potential loss of 547 IDR/head/day if selling price was only 40,000 IDR/kg live weight. Breakeven point could be reached at selling price of 44,500 IDR/kg live weight. It is concluded that fattened lambs is not profitably sold to general market but can be profitably sold to Aqiqah and Qurban markets.

Calves can be preconditioned using a wide variety of supplemental feed ingredients. However, feed ingredient selection is not the only factor to consider during a preconditioning process. Increasing the protein supply to stressed, preconditioning beef steers led to greater growth performance, and increased immune response to vaccination during a 42-day preconditioning period. Producers should not reduce the frequency of concentrate supplementation during the entire preconditioning period as it might lead to poorer vaccine response and average daily gain (consequently, less calf value at sale). However, a gradual reduction of frequency of supplementation is a supplementation strategy that can overcome these negative effects on growth and immunity, and allows producers to save on feeding and labor costs without producing lighter calves that have weaker immune responses.

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.

Abstract This study applied a chemical isotope labeling/liquid chromatography mass spectrometry-based metabolomics technique to determine differences in plasma metabolites containing amine/phenol and carbonyl chemical groups in beef steers with divergent average daily gain (ADG). Thirty-eight Angus crossbred beef steers (21 d post-weaning; 210 ± 12 kg of BW) from a single source were housed in individual slatted floor pens and were fed the same total mixed ration (CP = 14.5% and NEg = 1.10 Mcal/kg) ad libitum for 42 d with free access to water. After 42 days of feeding, the steers were divided into two groups of lowest ADG (LF: n = 8) and highest (HF: n = 8) ADG. Blood samples were taken from both LF and HF steers and were immediately centrifuged to harvest the plasma. The average daily DM intake of the steers in LF and HF were 6.08 kg ± 0.57 and 6.04 kg ± 0.42, respectively, and was similar between the two groups (P = 0.72). The ADG of LF (0.99 kg ± 0.23) was lower (P = 0.01) than that of HF (1.63 kg ± 0.20). A total number of 42 carbonyl-containing metabolites and 229 amine/phenol-containing metabolites were identified in the plasma samples of both groups. No alteration in carbonyl-metabolome was detected. Ten metabolites including 4,6-dihydroxyquinoline, prolyl-valine, prolyl-leucine, prolyl-isoleucine, L-formylkynurenine, pyrocatechol, and histidine were greater in HF steers whereas 8 metabolites including arginine, phenylalanine, guanidoacetic acid, and aspartyl-threonine were greater in LF steers. This study demonstrated that beef steers with divergent ADG had altered plasma amine/phenol metabolome. Notably, plasma concentrations of dipeptides containing branched chain amino acid residues (prolyl-valine, prolyl-leucine, prolyl-isoleucine) and metabolites with anti-inflammatory and reactive oxygen-scavenging properties (4,6-dihydroxyquinoline and L-formylkynurenine) were greater in steers with high ADG.

Abstract Objectives were to compare feedlot performance and carcass traits of F1 beef × Holstein steers and Holstein steers. Angus or Limousin × Holstein crossbred [n = 27; age = 12 ± 3 months; body weight (BW) = 435 ± 8 kg] and Holstein (n = 20; age = 11 ± 2 months; BW = 400 ± 9 kg) steers were fed at the Pennsylvania Department of Agriculture Livestock Evaluation Center for 111 days. Feed intake was recorded using the GrowSafe Feed Intake Monitoring System (Model 4000E, GrowSafe Systems Ltd., Calgary AB, Canada). The diet contained corn silage, dried distillers grains, soybean meal, and cracked corn and was formulated to meet or exceed the requirements of beef cattle (NASEM, 2016). Growth performance variables of interest and carcass measurements were analyzed with the Mixed procedure of SAS (SAS 9.4; SAS Institute Inc., Cary, NC). USDA assigned quality grades (QG) and yield grades (YG) were analyzed the with GLIMMIX procedure of SAS. Breed was a fixed effect in all models. There were no differences (P &gt; 0.05) between breeds in average daily gain or feed efficiency. Crossbreds exceeded Holsteins in initial (P &lt; 0.01) and final BW (P = 0.01), dry matter intake (P = 0.03), hot carcass weight (P &lt; 0.01), backfat (P = 0.03), and ribeye area (REA; P &lt; 0.01). Thirty-five percent (35%) of the Holsteins received a QG of Choice or above while 74% of crossbreds graded USDA Choice or above (P = 0.01). However, 75% of Holsteins were YG 2 or lower while only 45% of crossbreds achieved YG 2 or less (P = 0.05). There was no improvement in efficiency when crossbreds were compared to Holsteins; however, carcasses from crossbreds were more likely to grade USDA Choice or above while yielding greater REA and backfat than Holsteins.

UTILIZATION OF “GEDI LEAF (Abelmoschus Manihot (L) Medik) AS“ADDITIVE” IN DRINKING WATER RELATED TO THE PERFORMANCE OF INDONESIAN SUPER NATIVE CHICKEN. Research was done to evaluate the performance of Indonesian super native chicken treated with “Gedi” leaf (Abelmoschus Manihot (L) Medik) as“Additive” in drinking water. Study was conducted using hundred individuals of the Indonesian super native day old chicken. The juice of “Gedi” leaf (Abelmoschus Manihot (L) Medik) was given as in forms of the four treatments as follows, drinking water without “Gedi” leaf as control (P0), drinking water with 10 ml juice of “Gedi” leaf per liter of drinking water (P1), drinking water with 20 ml juice of “Gedi” leaf per liter of drinking water (P2), and drinking water with 30 ml juice of “Gedi” leaf per liter of drinking water (P3). Treatments were applied to the birds at 6 weeks old by completely randomized design five replications at each treatment. Data were taken during 5 weeks. Feeds were using 73 percents of commercial feed added by 10 percents of corn and 17 percents of rice bran with nutritional composition of crude protein 19.49 percents, crude fiber 4.66 percents, fat 3.63 percents, Calcium 1.02 percents, Phosphorus 0.66 percents and metabolic energy of 2920 kcal/kg, all given ad libitum. Variables measurement were focused on feed consumption, drinking water consumption, average daily gain, and feed conversion. Results showed that drinking water with 30 ml juice of “Gedi” leaf per liter of drinking water (P3) was not significantly different with other treatments for feed and drinking water consumption, except for average daily gain and feed conversion. The treatments of P1 and P2 were not significantly different for average daily gain, but these treatments were higher in average daily gain compared with control (P0). The highest value of feed conversion was obtained at treatment P3 and the lowest value was found at treatment P1. These values indicated that the best feed conversion was treatment P1. Therefore, it can be concluded that juice of “Gedi” leaf can be used as the alternative additive feed in drinking water up to 20 ml juice of “Gedi” leaf per liter of drinking water in term of high average daily gain and feed conversion of Indonesian super native chicken. Key words: Drinking water, “Gedi” leaf, Indonesian super native chicken.
