Abstract

An elicitation exercise was conducted to collect and identify pressing questions concerning the study of helminths in livestock, to help guide research priorities. Questions were invited from the research community in an inclusive way. Of 385 questions submitted, 100 were chosen by online vote, with priority given to open questions in important areas that are specific enough to permit investigation within a focused project or programme of research. The final list of questions was divided into ten themes. We present the questions and set them briefly in the context of the current state of knowledge. Although subjective, the results provide a snapshot of current concerns and perceived priorities in the field of livestock helminthology, and we hope that they will stimulate ongoing or new research efforts.

Abstract

Our objective was to determine the effect of vaccination and deworming at arrival (d 0) on bovine respiratory disease (BRD) incidence, mortality, and growth of Stocker calves. Calves (n=80) were stratified by d -3 weight and fecal egg count (FEC) into 20 pens of 4 calves. Pens were randomly assigned to treatments in a 2x2 factorial design, testing d 0 vaccination (modified-live respiratory virus and clostridial vaccine, or not) and deworming (oral fenbendazole and levamisole, or not). Body weights were measured on days 0, 14,28,42, 56, 70, and 85, and FEC were measured on days -3, 28, 56, and 85. Incidence of BRD was greater for d 0 vaccination (RR=3.2), high fever (>104°F, >40°C) at d 0 (RR=6), and higher d -3 FEC (RR=1.2 per 100 epg). Mortality was greater for d 0 vaccination (OR=8.3) and high fever (OR=41.6). Growth was 10.3 lb (4.7 kg) lower for d 0 vaccination, 24 lb (11 kg) and 16 lb (7.3 kg) lower for moderate (103°F to 103.9°F; 39.4°C to 39.9°C) and high fever, respectively, and 17.6 lb (8 kg) lower for each additional BRD treatment a calf received. Deworming was neither beneficial nor detrimental to any health or performance factors. Health and growth performance of Stocker calves may be adversely affected by vaccination at arrival, higher arrival FEC, and fever at arrival., The Bovine Practitioner, Vol. 52, No. 1 (2018 Spring)

87. Modelling anthelmintic resistance by extending eggCounts package to allow individual efficacy

Abstract

The same anthelmintic treatment can have variable efficacy on individual animals even if the parasite population is homogenously susceptible. An extension of the R package eggCounts is proposed to take individual efficacy into account using a Bayesian hierarchical model. A simulation study is conducted to compare the performance of five different methods on estimating faecal egg count reduction and its uncertainty interval. Simulation results showed the individual efficacy model offered robust inference to two different data simulation procedures with low root mean squared error on the reduction estimate and appropriate uncertainty estimates. Different methods were used to evaluate the anthelmintic resistance in a dataset from USA with sheep and cattle faecal egg counts, where a strong anthelmintic resistance was detected. Open-source statistical tools were updated to include the proposed model.

88. How to improve the standardization and the diagnostic performance of the fecal egg count reduction test?

Abstract

Although various studies have provided novel insights into how to best design, analyze and interpret a fecal egg count reduction test (FECRT), it is still not straightforward to provide guidance that allows improving both the standardization and the analytical performance of the FECRT across a variety of both animal and nematode species. For example, it has been suggested to recommend a minimum number of eggs to be counted under the microscope (not eggs per gram of feces), but we lack the evidence to recommend any number of eggs that would allow a reliable assessment of drug efficacy. Other aspects that need further research are the methodology of calculating uncertainty intervals (UIs; confidence intervals in case of frequentist methods and credible intervals in case of Bayesian methods) and the criteria of classifying drug efficacy into ‘normal’, 'suspected’ and ‘reduced’. The aim of this study is to provide complementary insights into the current knowledge, and to ultimately provide guidance in the development of new standardized guidelines for the FECRT. First, data were generated using a simulation in which the ‘true’ drug efficacy (TDE) was evaluated by the FECRT under varying scenarios of sample size, analytic sensitivity of the diagnostic technique, and level of both intensity and aggregation of egg excretion. Second, the obtained data were analyzed with the aim (i) to verify which classification criteria allow for reliable detection of reduced drug efficacy, (ii) to identify the UI methodology that yields the most reliable assessment of drug efficacy (coverage of TDE) and detection of reduced drug efficacy, and (iii) to determine the required sample size and number of eggs counted under the microscope that optimizes the detection of reduced efficacy. Our results confirm that the currently recommended criteria for classifying drug efficacy are the most appropriate. Additionally, the UI methodologies we tested varied in coverage and ability to detect reduc

92. Assessment of gastrointestinal nematode parasitism in dairy calves housed in calf hutches

Abstract

Gastrointestinal nematodes (GIN) are an important cause of morbidity and production losses in cattle. Clinical infection with GIN can cause diarrhea and hypoalbuminemia, but subclinical infections are more prevalent, harder to recognize, and a greater threat to productivity. Emphasis in the dairy industry has been placed on management strategies to mitigate disease and productive losses caused by GIN infections in grazing heifers and adult cattle, but hutch calves have largely been left out of this discussion. Milk-fed dairy calves housed in hutches are presumed not to acquire GIN infection because transmission of GIN is thought to require exposure to a pasture environment and subsequent ingestion of contaminated forage. However, a recent assessment of fecal egg counts (FEC) in hutch calves for another research project revealed calves raised in hutches with unexpectedly high FEC. The objective of this study was to estimate the prevalence and magnitude of GIN in hutch calves on two calf ranches and to evaluate factors associated with the probability for calves to be parasitized., American Association of Bovine Practitioners Proceedings of the Annual Conference, 2017

Abstract

Anthelmintic resistance is a worldwide problem in all livestock systems, with most reports of resistance in cattle parasites being to the macrocyclic lactone (ML) drug class. Several prevalence studies performed internationally demonstrate that anthelmintic resistance in cattle parasites is a growing problem, however, no similar studies have been performed in the US. The primary objective of this study was to gain data on the prevalence of ML resistance in gastrointestinal nematode (GIN) parasites on beef cattle farms in Georgia. We also wanted to test the efficacy of combination anthelmintic therapy in these same herds, and use these data as a basis for educational outreach programs for beef producers in Georgia., American Association of Bovine Practitioners Proceedings of the Annual Conference, 2017
