Due to increasing bacterial antibiotic resistance and the consumers’ tendency to choose organic products, cattle farmers are interested in alternative methods of calf diarrhoea treatment. This is a major challenge for veterinarians. Few methods of non-antibiotic treatment that bring satisfactory results have been reported in the related literature so far. In this article, the authors compare different non-antibiotic methods of diarrhoea prevention and treatment in calves. Among the alternatives discussed are herbs, probiotics, prebiotics and synbiotics, lactoferrin, and bacteriophages. It was found that the best results could be achieved through the use of pro-, pre- and synbiotics. However, the authors would like to point out that with the expansion of knowledge about the practical use of broad-scale bacteriophages, they could be the best alternative to antibiotics.

A research project is underway aiming to develop a field diagnostic tool for six important viruses of the pig sector, namely: African swine fever virus (ASFV), porcine reproductive and respiratory syndrome virus (PRRSV), swine influenza virus (SIV), porcine parvovirus (PPV), porcine circovirus (PCV2), and classical swine fever virus (CSFV). To obtain a preliminary sounding of the interest in this type of instrument among its potential operators, a questionnaire was drawn up and submitted to three categories of stakeholders: farmers, veterinarians, and others (including scientific and technical staff working on animal farms). Four countries participated: Italy, Greece, Hungary, and Poland. In total, 83 replies were collected and analysed in a breakdown by stakeholder type and pertinence, where the areas were the importance of the main diseases within the different countries, diagnostic tool operational issues, and economic issues. The main end-users of this kind of instrument are expected to be private veterinarians and pig producers. The infectious agents seeming to be most interesting to diagnose with the instrument are PRRSV, SIV, PPV, and PCV2. The most decisive parameters which have been selected by the stakeholders are sensitivity, cost, simplicity, and time required to obtain results. The economic issue analysis showed that the majority of those who would prefer to buy rather than rent the device are willing to pay up to €3,000 for a diagnostic field tool.

White sturgeon iridovirus (WSIV) disease is caused by a virus of the eponymous family and is mostly triggered by stressful environmental conditions, i.e. high rearing density, excessive handling, or temporary loss of water. The aim of this study was to develop the most effective diagnostic method for quick and efficient confirmation or exclusion of the presence of WSIV. A total of 42 samples (spleen, gills, intestine, skin, kidney, and brain) were collected from eight sturgeon (Acipenser gueldenstaedtii and A. oxyrinchus) aged ≤5+ farmed or caught between 2010 and 2014 in open waters (Dąbie Lake and Szczecin Lagoon). They were tested for WSIV presence using conventional PCR, qPCR, and in situ hybridisation (ISH). In gross examination, all fish appeared to be healthy. Neither species showed clinical signs typical of WSIV infection. In the majority of cases, fragments of iridoviral DNA were found using molecular methods in the kidneys, and also in the liver, gills, and skin. The detection rate using ISH was 47.37% and most commonly the brain and kidney tissues were positive. The most efficient of the methods used was real-time PCR, with 100% effectiveness in detection of WSIV DNA. The study demonstrates the capabilities for WSIV diagnosis available to sturgeon farmers and water administrators, indicating useful methods of adequate sensitivity as well as organs to sample in order to achieve the highest probability of viral detection.

The South African government recognises the value of traditional healing and supports an integrated healthcare system. In the veterinary field, successful integration depends on the perceptions of different animal healthcare practitioners (AHCPs). This study aimed to determine the perceptions of ethnoveterinary medicine among state-employed veterinarians and animal health technicians in the North West province. A mixed model questionnaire and non-probability sampling gathered quantitative and qualitative data from 53 participants. Statistical and thematic analysis processes were applied to quantitative and qualitative data, respectively. Overall, 77.4% of participants were aware of ethnoveterinary medicine practices. Approval of the use of ethnoveterinary medicine by farmers was above-average at a mean of 3.57, standard deviation (s.d.) = 1.016 on a 5-point Likert scale. However, 65.9% doubted the effectiveness of ethnoveterinary medicine, which suggests tolerance but no appreciation of its value. The Chi-square test revealed a significant relationship between district municipality of employment and awareness at χ2 = 17.490, df = 3, p = 0.001. Thematic analysis of comments showed that some participants perceived ethnoveterinary medicine as unscientific and interfering with Western veterinary medicine, while some considered it a good complement to Western veterinary medicine. The study also found that 20.8% of AHCPs use ethnoveterinary medicine to treat certain diseases. In conclusion, the lack of appreciation for ethnoveterinary medicine among AHCPs may hinder government-proposed integration, emphasising the need for programmes to improve perceptions among these stakeholders. Contribution: This is first such study to report on perceptions of ethnoveterinary medicine among AHCPs, and assess their readiness for an integrated animal health system.

Methicillin-resistant Staphylococcus aureus (MRSA) and Clostridium difficile are important human pathogens that are also carried by animals. The role of wild mammals on farms in their maintenance and transmission, however, is poorly understood. To determine if Norway rats (Rattus norvegicus) are potential carriers of these bacteria on Canadian farms, we tested 21 rats from swine farms in Ontario. The MRSA spa type t034 was isolated from 1 (4.8%) rat. This livestock-associated strain often colonizes pigs and pig farmers, suggesting that transmission among rats and pigs or environmental transmission is possible on pig farms. Clostridium difficile ribotype 078 was isolated from 1 rat from a different farm. This strain is associated with infection in piglets, calves, and humans. The identification of MRSA and C. difficile in Norway rats on farms in Canada adds to the growing knowledge about the role of rats in the ecology of these pathogens. Further studies are required to determine if rats play a part in the epidemiology of these pathogens on farms.

A cross-sectional study was designed to determine the level ofawareness of selected dairy farmers to herd health program (HHP) and compliance in the Program LadangAngkat (PLA). The study also determined the association between farmers’ awareness and compliance in promoting herd health. An open-ended questionnaire was randomlyadministered to five dairy cattle farms within Selangor and Negeri Sembilan as representative dairy farms enlisted into the PLA of Faculty of Veterinary Medicine, Universiti Putra Malaysia. The mean herd size of the farms was 102.20±20.80, with a range of 30-160 heads of dairy cattle, having an average mean number of milking cows at 29.40±11.22. There was a higher (p<0.05) mean herd health awareness level (72.86±5.78%) among the farmers once compared with the mean compliance level (61.2 ± 4.1%) for 10 out of the 14 HHP components; with the lowest compliances being disease monitoring programme(33.20%) and biosecurity (39.9%). There was a significant (p<0.05), direct, weak positive correlation (r = 0.245; p = 0.042) between farmers’ awareness and farmers’ compliance to the 14 components of the HHP. This study highlights an appreciable level of awareness among dairy farmers in the PLA, with a relatively low compliancelevels to the HHP components.

Traceability system for livestock is an important infrastructurenecessary to monitor animal health, animal disease emergencies and quality assurance. The aim of this study was to evaluate farmer and trader willingness to use and pay for an animal identification and traceability system in Peninsular Malaysia. Data was obtained from aquestionnaire that was completed by 543 farmers and traders from the 10 states in the peninsula. Our results show that up to 54% respondents were willing to use and pay for an animal identification and traceability system. Gender and the length of experience of farmers and traders were factors significantly associated with theoutcome of this study. Female farmers and traders were less willing to use and pay for an animal identification and traceability system while farmers and traders with more experience in the cattle industrywere significantly more likely to provide a favourable response.

This study was done to evaluate the status of resistance to nematode populations on four major groups of anthelminthics. Nematode faecalegg count reduction tests (FECRT) were conducted on six free grazing small holder goat farms (namely Farms A-F) in Perak.The four drug groups tested in this study were Benzimidazoles, Imidazothiazoles,Macrocyclic Lactones and Salicylanilides. Faecal samples were subjected to the standard procedures of McMaster for worm egg estimation and also larval cultures for third stage larvae identification. Results of Farm A, Farm C and Farm D showed resistance to all 4 drugs groups of anthelminthic that were tested and the major worm population of this farm were Haemonchus contortus (49.75%), Trichostrongylus colubriformis (47.71%) and Cooperia sp. (2.53%). The results of Farm B and Farm F showed resistance to all the 3 groups of anthelminthics except Levamisole and the worm population of this farm was Haemonchus contortus (47.30%), Trichostrongylus sp. (38.44%), Oesophagostomum columbianum (13.50%) and Cooperia sp. (0.76%) Farm E was resistant to Benzimidazoles andsuspected resistance to 3 drugs groups; Levamisole, Macrocyclic Lactones and Closantel. The worm population for Farm E was Haemonchus contortus (71.35%), Trichostrongylus sp. (27.6%) and Oesophagostomum sp. (2%). These farms have a history of using the same anthelminthics over the past few years, thus leading to the severe case of anthelminthic resistance. Recommendations have beenmade to control helminths using alternative approaches such as cut and carry feeding, herbal medication using Neem leaves (Azadirachta indica) and rotational grazing as well as improvement in management of animals to increase their immunity.

Four types of products made from Neem namely, neem leaf decoction, neem capsule, neem fresh juice and neem extract were given to 4 groups of goat for a period of 10 weeks to evaluate the effectiveness of these products in controlling natural gastrointestinal helminth infection. During the course of the study, faecal egg counts, Packed Cell Volume and FAMACHA readings were&#xD;monitored weekly. Results of feeding these products were variable when compared to untreated control animals, however, a 40-60% worm control was observed. Further testing is required to fine tune these&#xD;products for use in the field especially where anthelmintic resistance deems drugs to be ineffective.

Parasitic helminth infections in small ruminants are prevalent in South East Asia (SEA), limiting productivity and causing major economic loss for farmers. The hot, wet, tropical climate all year&#xD;round favours trichostrongylid infections, predominantly haemonchosis in sheep and goats. Commercial large scale farms, with&#xD;more than 300 animals, as well as small holders or backyard farmers with less than 50 animals face the debilitating effects of haemonchosis when they graze their animals as effective worm control is often hampered by anthelmintic resistance. In Malaysia, frequent and indiscriminate use of anthelmintics in the past has resulted&#xD;in the majority of the small ruminant population facing resistance to one or more anthelmintics. Several alternative methods of worm control are being employed by farmers; the most important and effective being cut and carry or zero grazing, where the animals are kept in pens and grass is cut and fed. In Cambodia and Myanmar,&#xD;ruminants are still tethered or stall fed with minimal drug use. In Indonesia and Thailand, commercial goat and sheep farms are fast expanding to produce breeder stock for the SEA market. However, up to&#xD;75% of the small ruminant population is still traditionally managed by small scale farmers. In most of SEA, the McMaster method for faecal worm egg counts is the only diagnostic test used to assess helminthosis in ruminants. There is an urgent need to increase awareness and information on the need for testing faecal samples regularly before drenching, conducting faecal egg count reduction tests on a yearly basis, use of the FAMACHA technique to enable&#xD;selective treatment of individual animals. The use of alternative worm control methods to manage helminthosis will help promote effective ruminant production with reduced drug use and ncourage “green” farming methods. Extension of research on local bioactive plants which may have the potential to control helminthosis may also be beneficial in the longer term.
