Effect Of Treatment

Abstract Mass medication to manage population health can be achieved by providing therapeutics in the drinking water. Young nursery pigs are highly sensitive to the flavor and smell of water. Medications that reduce water palatability often lead to an interruption in water and feed intake. With the availability of several generic water-soluble antimicrobials for pigs, questions have arisen about their palatability compared with the original product. In this study, we compared the intake of water containing tiamulin hydrogen fumarate from two different manufacturers with the intake of unmedicated water. The hypothesis was that the intake of tiamulin-containing water would be similar to unmedicated water. Water intake was monitored upon entry into the nursery and just prior to leaving the nursery. Also, average daily gain (ADG) and feed efficiency (FE) were determined. A total of 300 pigs were individually weighed (4.2–10.9 kg; avg = 6.8 kg) for randomization to pen (n = 30 pens). The experiment had two time points: 1) early nursery (periods 1–3) and 2) late nursery (period 4). Pens were randomly assigned to a sequence (period 1–3) in a crossover experimental design containing three 10-d periods, with 5 d for the resetting of baseline where unmedicated water was provided followed by 5 d on tiamulin source addition [i.e., TriamuloxTM (Zoetis, Parsippany, NJ); Denagard (Elanco Animal Health, Greenfield, IN)] or unmedicated water. After period 3 was concluded, all pens were given unmedicated water (via nipple waterers) and the number of pigs per pen was reduced to six pigs to maintain adequate space per pig. Ten days prior to pigs leaving the nursery, a fourth period was performed. After a 5-d water baseline was achieved, pens were treated with either unmedicated water or Triamulox- or Denagard-containing water. Pigs had ad libitum access to water and feed. During the testing periods, daily water intake was measured by a cup water system in each pen. Feed intake was measured every 5 d. There was no effect of treatment on initial body weights or weights at the beginning or end of each period (P ≥ 0.51). Therefore, there was no effect of treatment on ADG (P ≥ 0.23). Water intake (P ≥ 0.16) and FE (P ≥ 0.35) were not affected by treatment. Water consumption was similar among all treatments in each of the four periods. There appears to be no aversion to water intake when tiamulin hydrogen fumarate is added to the drinking water.

Abstract This experiment compared physiological and productive parameters in finishing cattle managed under heat stress conditions, and supplemented or not with Omnigen-AF (Phibro Animal Health, Teaneck, NJ). Crossbred cattle (Bos taurus × B. indicus; 64 heifers and 64 steers) were ranked by initial body weight (BW; 440 ± 3 kg) and sex, and allocated to 1 of 16 pens (8 heifers or steers/pen). Pens within sex were randomly assigned to receive (OMN; n = 8) or not (CON; n = 8) Omnigen-AF at 56 g/cow daily (as-fed basis). Cattle received a total-mixed ration during the experimental period (d 0 to 107), and Omnigen-AF was offered daily as a top-dress to OMN. Cattle were shipped on d 107 to a commercial packing facility for slaughter. Cattle BW was recorded and samples of blood and tail-switch hair collected on d 0, 28, 56, 84, and 106. Feed intake was evaluated biweekly from each pen, and feed efficiency calculated according to total feed intake and BW gain of each pen. From d 0 to 7, 28 to 42, and 84 to 98, heifer intravaginal temperature was recorded hourly (iButton temperature loggers DS1922L, Maxim Integrated, San Jose, CA). Environmental temperature humidity index (THI) was also recorded hourly throughout the experiment, and averaged 79.8 ± 0.6. Heifers receiving OMN had less (P < 0.05) vaginal temperature from 1500 to 1900h (39.05 vs. 39.19 °C), when THI ranged from 85.3 to 90.1. No treatment effects were detected (P > 0.20) for BW gain, feed intake, feed efficiency, and carcass traits. No treatment effects were also detected (P > 0.17) for plasma concentrations of cortisol and haptoglobin, and cortisol concentrations in tail-switch hair. Hence, OMN ameliorated hyperthermia in finishing cattle exposed to heat stress conditions, but such benefit was not sufficient to improve productive and physiological responses.

Daily Gain

One hundred and twenty commercial feedlot steers were penned and randomly allocated to three treatments: fed once, twice and three times per day, over a grower through finisher period of 196 d. Feeding frequency had no effect (P > 0.05) on average daily gain, feed intake or efficiency overall. We conclude that there are no beneficial effects in feeding a total mixed diet more frequently to feedlot steers. Key words: Feeding, frequency, gain, steers, feed efficiency

Four trials, three in the United States and one in South Africa, were conducted to evaluate the potential value of a novel self-medicating applicator in the passive control of gastrointestinal nematodes in cattle and deer, and of flies and ticks on cattle using oil-based treatments. The results of the trials demonstrated that this applicator is an effective and practical device for the passive treatment of both deer and cattle for trichostrongyle infections using the endectocide, moxidectin (Cydectin (R) , Fort Dodge Animal Health, USA), of cattle for horn fly (Haemotobia irritans) infestations using the insecticide, cyfluthrin (CyLence (R) , Bayer AG, Germany) and of cattle for tick infestations (in particular Amblyomma hebraeum and Rhipicephalus appendiculatus) using the acaricides deltamethrin and amitraz (Delete All (R) , Intervet, South Africa).

Meal Time

The effects of different feeding regimes during the lactation period on feed intake, body reserves and sow performance were evaluated. A 2 × 2 factorial design was used and 183 first-parity sows were randomly allocated to one of four treatments: sows were fed either two or three meals per day with (wet feed) or without (dry feed) supplemental water at meal time. Primrparous sows were fed ad libitum 12–16 h after parturition. The addition of water at meal time increased (P < 0.01) feed consumption by 5% over the 18-d lactation period. Increased feeding frequency did not influence feed intake. During the first week of lactation, most sows gained weight, but thereafter lost weight, with the rate of weight loss reaching a peak during the last week of lactation. Although feed intake was influenced only by wet feeding, both an increased frequency of daily meals and the use of wet feeding reduced mobilization of body reserves. Wet-fed sows lost less weight than dry-fed sows and the increased feeding frequency reduced backfat loss. Average daily gain of piglets, percentage of sows with a weaning-to-estrus interval of less than 7 d, farrowing rate, and parity-2 litter size were similar among the four groups. A lack of significant improvement in sow performance with different regimes may be partly related to a generally high feed intake and minimal weight and backfat losses. Although our results failed to show a benefit on sow performance, we believe that some of the feeding strategies evaluated could be useful during periods in which sows eat less, such as in the summer, or in some herds that have feed consumption problems. Key words: Sow, feed intake, weight, backfat, reproductive performance

ABSTRACT A 25-amino-acid synthetic peptide (C6 peptide) derived from an immunodominant conserved region (designated IR6) of the VlsE protein of Borrelia burgdorferi has been identified and used to construct immunoenzyme-based diagnostic procedures. These procedures have excellent sensitivity and specificity. Previous reports have demonstrated the usefulness of the C6 peptide as an antigen for the serodiagnosis of human and canine Lyme disease. Results indicated that assays based on the C6 peptide were nonreactive to sera from vaccinated nonexposed animals. The purpose of the present study was to confirm these results in a controlled trial by testing sera from experimentally vaccinated dogs known to be uninfected. Nine specific-pathogen-free beagles were assigned to one of three vaccine groups, each containing three dogs. Each group received one of three commercial Lyme vaccines: RECOMBITEK Lyme (Merial), LymeVax (Fort Dodge Animal Health), and Galaxy Lyme (Schering-Plough Animal Health). Each animal was administered a total of five doses of vaccine over a period of 39 weeks. Serum samples were collected prior to vaccination and then on a weekly basis from weeks 3 to 18 and from weeks 33 to 43. Selected samples were tested by the immunofluorescence assay (IFA) and the Western blot (WB) assay using whole-cell B. burgdorferi antigen extracts, and the results were compared to those obtained with two immunoenzyme-based procedures formatted by using the C6 peptide. Serum specimens from all animals were reactive to the IFA and WB assay at week 5 and became highly reactive following the administration of multiple doses of vaccine. All serum specimens were uniformly nonreactive in the C6 peptide immunoenzyme procedures at all time points throughout the study.

An experiment was conducted to evaluate the expression of insulin-like growth factor-I (IGF-I) and IGF-binding proteins (IGFBPs -II and -III) in response to a 10% inclusion of caramel plant wastewater (CPWW) in weaning pig diets; the objective was to assess associations between those growthrelated proteins to feed intake (Fl) and body weight gain (BWG). Sixteen purebred Landrace piglets were randomly distributed among eight pens (a gilt and boar per pen) and assigned to one of two treatments: 0% (control) and 10% inclusion of CPWW. During four consecutive weeks, live weight and Fl were recorded. Blood samples were drawn by jugular venipuncture during the first, second, and third weeks of the experiment and serum levels of IGF-I, IGFBP-II and IGFBP-III were determined. Feed intake, BWG and feed efficiency (FE) were not affected (P > 0.05) by the addition of 10% CPWW tothe diet, nor was animal health status visibly affected. Serum IGF-I levels were higher in control animals (P < 0.05) and increased from d 14 to d 28 of the experimental period (P < 0.05). Weekly increases were observed for IGFBP- III (P < 0.05) whereas IGFBP-II circulating levels decreased from d 14 to d 28 of the post-weaning test period. Simple correlation analysis revealed that there was a positive association between circulating levels of IGF-I and IGFBP-III (r = 0.88; P < 0.0001). However, the opposite was observed between these two and IGFBP-II (r = -0.84, P < 0.0001; r = -0.67, P < 0.0025, respectively). The changes observed in circulating levels of IGF-I, IGFBP-III and IGFBP-II were associated with weekly increases in Fl and BWG that occurred during the entire experimental period (P < 0.05).
