Pasture Contamination

Small ruminants in northwestern Spain are frequently managed in mixed flocks. Sheep–goat joint management has not been considered a risk factor for parasite infection, so the main objective of this study was to establish if mixed management with goats supposes a risk factor for parasitic infections in ovine flocks. Two thousand and ninety-three sheep were sampled from 74 commercial meat ovine flocks for diagnostic of the main parasites. Goat contact was a risk factor for sheep to be infected by protostrongylids, Dictyocaulus filaria, gastrointestinal nematodes and Eimeria spp. In contrast, Moniezia, Fasciola hepatica, Dicrocoelium dendriticum and Paramphistomidae prevalences were not influenced. Sheep–goat mixed management can be considered as a risk factor, since goats would act as a source of pasture contamination for interspecific parasites (protostrongylids, Dictyocaulus filaria and gastrointestinal nematodes). In relation to host-specific parasites, such as Eimeria spp., goats cannot be considered as a source for sheep, but competition for food and spaces between both small ungulates can suppose a reduced grazing area to sheep, provoking high environmental contamination and stress that facilitate their infection. Future epidemiological studies for parasitic infections in small ruminants should consider sheep–goat mixed management as a possible risk factor to be included in multivariate analyses.

This study was conducted in order to determine the presence of parasitic infections of the Greek buffalo (Bubalus bubalis) in the Prefecture of Serres, Northern Greece. During the period from February to October 2014, faecal samples from 110 buffaloes of the Greek buffalo breed (Bubalus bubalis), from 9 farms located in proximity to Lake Kerkini, in the Prefecture of Serres, Northern Greece, were examined, in order to find reproductive elements of parasites. Out of 110 faecal samples examined, 102 (92.73%) were found infected with reproductive elements (eggs, larvae, cysts and oocysts) of parasites. Specifically, the parasites found were: Eimeria spp. (40%), Entamoeba bovis (16.36%), Paramphistomum cervi (10%), Fasciola hepatica (16.36%), Dicrocoelium dendriticum (28.18%), Moniezia benedeni (27.27%), Toxocara vitulorum (11.82%), Strongylida (gastrointestinal nematodes) (31.82%) and lungworms (28.18%). The present study appears to be the first report of the detection of lungworms in buffaloes, in Greece.

Abstract Animals reared in restricted environments are highly susceptible to gastrointestinal infection by helminths and protozoa and therefore zoos are characterized as being parasite-rich environments. Successful implementation of control programs of these parasites in zoo environment depends upon precise and rapid diagnosing of gastrointestinal infections. The aim of this study was to demonstrate the role of the Mini-FLOTAC technique in combination with Fill-FLOTAC for rapidly diagnosing parasitic infections in zoo mammals. Fecal samples were collected from 70 animals in four different zoos located in central and southern Italy. All the samples were analyzed using Mini-FLOTAC in combination with Fill-FLOTAC. Out of the 70 pooled samples examined, 80% (24/30) were positive for at least one parasite. Among the gastrointestinal nematodes, Strongyles were the most frequent (40%), followed by Trichuris spp. (23.3%), Parascaris spp. (13.3%) and Capillaria spp. (3.3%). Among the protozoa, Blastocystis spp., Giardia spp. and Eimeria spp. were detected in 6.6%, 3.3% and 3.3%, respectively. These results show that Mini-FLOTAC in combination with Fill-FLOTAC can be used, not only for rapidly diagnosing parasitic infections in zoo mammals, but also for monitoring control programs in which large numbers of fecal samples need to be examined rapidly and reliably.

SummaryThe objective was to highlight the role of supplementary feeding on resilience and resistance of browsing small ruminants against natural gastrointestinal nematode (GIN) infections. GIN infections have a negative impact on productivity of browsing Criollo kids especially during the wet season of Yucátan. Epidemiological studies have demonstrated the threat of GIN infectivity in the native vegetation available for browsing goats. Control of GIN in browsing ruminants is threatened by the emergence of anthelmintic resistant nematodes strains in the local flocks. Browsing trials with kids and lambs have shown that supplementary feeding (100–108g/day) improved resilience and resistance of Criollo kids against GIN. Supplements used successfully include sorghum:soybean meal (74:26 respectively), maize:soybean meal (74:26) and maize only (108g/day). The later result showed that animals might benefit from supplementation with rumen fermentable energy that could improve utilization of available browsing legumes by the goats. Wet season trials showed that, in spite of supplementation, infected animals have lower productivity compared to non-infected animals. However, the combined use of supplementation and copper oxide wire particles or tactic anthelmintic treatment, can improve growth rate of infected kids to maximum production levels. Short-term supplementation strategies have shown to be less effective than long-term strategies in achieving better resilience against GIN in kids. Lambs are more resistant but less resilient against GIN infections than kids. Improved resistance of lambs seemed to require more nutrients than in goats. In conclusion, supplementary feeding can play an important role in improving both resilience and resistance of growing small ruminants in the tropics but it can be further improved through the complementary use of other strategies leading to a more sustainable integrated parasite control strategy.

The aim of the study was to compare the prevalence and intensity of gastrointestinal parasitic infections in goats kept on organic (n = 76) and conventional farms (n = 82). In general, a higher prevalence of some gastrointestinal parasitic infections was found in the conventional farms compared to the organic farms: the mean prevalence of Eimeria spp. was 85.4% in conventional farms and 77.6% in organic farms, that of Fasciola hepatica was 6.10% in conventional farms and 2.63% in organic farms, and that of Moniezia expansa was 31.7% and 17.1%, in conventional and organic farms, respectively. Both farm types demonstrated a similar mean prevalence of nematodes (80.3 vs. 84.2%). Conventional farms demonstrated a significantly higher intensity of infection with E. arloingi, Haemonchus spp., Nematodirus spp. and Moniezia expansa compared to organic farms. They also demonstrated a higher intensity of infection with Eimeria spp. than organic farms. The prophylactic programs used to combat parasitic infections in both types of farms appear ineffective and require improvement. There is a need for goat herds to be covered by ongoing parasitological monitoring. It is also recommended that keepers employ rotational or intensive rotational grazing methods and take care to ensure the hygiene of animal quarters and livestock rooms.

Internal Parasites

The changes in the cattle farming system in Poland observed in the last two decades and related to its evolution into massive scale, specialized farming may have an influence on the occurrence of parasitoses. The study was aimed at showing differences in the prevalence of internal parasites in cattle depending on the herd size, management system and production type. In the period of October to December in 2016 and 2017, the study covered 46 farms with a livestock density from 2 to 160 animals (over 1 year of age), including 25 farms with a confined management system, 12 farms using pastures occasionally and 7 farms with animals using pastures during the whole season. Out of these farms, 36 were oriented towards dairy cattle and 10 to beef cattle. The analytical methods involved flotation, sedimentation and the Baermann technique. In total, 276 feces samples were analyzed. The analysis involved a representative number of samples from each farm, depending on the herd size: from 100% of the animals in the smallest farms to 10% in the largest ones. In total, eleven different taxa of parasites were identified, and their general prevalence was as follows: Eimeria spp. 24.6%, Buxtonella sulcata 25.7%, Strongyloides papillosus 7.6%, gastrointestinal nematodes (Trichostrongylidae, Chabertia, Oesophagostomum) 35.1%, Nematodirus spp. 4.7%, Bunostomum phlebotomum 7.6%, Trichuris spp. 6.2%, Fasciola hepatica 6.9%, Paramphistomum spp 2.5%, Moniezia spp. 2.9%, Dictyocaulus viviparus 2.5%. The forms of parasites were found in samples coming from all studied herds. Invasions of protozoa (Eimeria, Buxtonella) were most commonly found in dairy cattle, in large herds managed in a free stall barn system and in beef cattle, in large herds managed in a pasture system. These herds were also most frequently infected with gastrointestinal nematodes. The invasions of trematodes, tapeworms and pulmonary nematodes were detected only in cattle using pastures, most commonly in large herds..

And Control

Gastrointestinal parasite infection in small ruminants remains one of the major economic losses caused by reduced productivity. A total of 380 faecal samples were taken from 280 sheeps in Magway and Pwintbyu Townships and 100 goats in Natmauk Township, Myanmar. Faecal flotation and sedimentation methods were carried out to detect the presence of parasitic infections. Faecal egg and oocyst counts were carried out using the McMaster technique. The overall occurrence of gastrointestinal parasites in small ruminants was 98.4% (374/380). The occurrence of gastrointestinal parasites in sheep (99.3%) was higher than that in goats (96%). The highest occurrence was found in Eimeria spp. (96%), followed by Trichostrongyle (77.1%), Trichuris spp. (35%), and Moniezia expansa (14%). The mixed infection rate was 84.8% (317/374), while a single infection was 15.2% (57/374). The mean eggs per gram (EPG) and oocysts per gram (OPG) of faeces were ranged from 50 to 600 and 50 to 29,800, respectively. Among the 4 nucleotide sequences isolated, one sequence was 94.10-94.47% similarity with Trichostrongylus colubriformis, reported from Laos, and three sequences showed 96.64-99.46% identity with Haemonchus contortus from Laos, China, India, and Mongolia. As gastrointestinal parasite infection in small ruminants was relatively high in the study area, the development of appropriate treatment and control measures should be provided to reduce production losses.

Collection Methods

The economic losses caused by gastrointestinal nematodes are one of the biggest obstacles in the small ruminants production. Understanding the population dynamics of the infective larvae (L3) in the pasture is the key point to develop control programs, and reliable results depend on the used methodology to quantify L3 numbers. The use of the sampling directly from the pasture appears as a viable option, since it is not required the use of animals with an esophageal fistula or tracer animals, decreasing the costs involved in the study. Therefore, the present project, which had as objective evaluate the efficiency of two collection methods for quantification of L3 in the pasture, utilized 64 lambs (n = 16) allocated to four integrated crop-livestock systems (treatments) with 12 paddocks each. Pasture samples were collected every nine days. The W method consists in traversing the area in the form of a W and again an inverted W, forage samples being collected every 10 steps, and the Square method, in tossing a 0.16 m2 square to four random points within the area, the forage within the square being collected after each toss. After the forage samples had been processed, the L3 were recovered and identified. Cohen’s Kappa coefficient (k) was determined. The W-transect and Random-plot methods did not differ (p ? 0.05) with respect to the number of L3 recovered from the pasture, and a positive correlation was found between them, suggesting agreement with one another, being that when the number of L3 recovered by the W-transect method increases, the same occurs in the Random-plot technique. The Random-plot method, which is already used to collect samples of forage for chemical analyses, can also be employed to estimate the pasture contamination by L3. The W-transect and Random-plot methods showed to be important in the epidemiological study of gastrointestinal nematodes in sheep. Therefore, the use of both on the same occasions and with different purposes, with one complementing the information that is not provided by the other, may be more effective in the investigation of environmental contamination by L3 of gastrointestinal nematodes.

Management Principle

Control of the gastrointestinal parasites in different systems of ruminant breeding is based on vaccination, chemotherapy, improved herd management and use of genetic potentials of host animals. Strategy of the helminths control based on frequent anthelmintics usage is dominant among the world, although it is considered unsustainable due to the appearance of increased number and species of parasites that are resistance to drugs. Development of resistance on all three groups of broad-spectrum antihelmintics (nicotinic anthelmintics, benzimidazoles and macrolides lactones) as well as increased care for consumers heath caused by appearance of used drugs residues in food, additionally complicate overall nematode control. With the aim to decrease appearance of anthelmintics resistance of gastrointestinal nematodes of small ruminants and in order to organize process of sustainable integrated parasite management, principle of targeted selective treatment is globally accepted. Implementing of this strategy has only recently become feasible, with development and practical use of systems that serve for clinical assessment of anemia in small ruminants which suffer from hemonchosis. Besides that, short term changes in body weight and body condition scoring may be indicators of diseases caused by endoparasites, as it can provide rapid identification of animals that will probably have benefits from therapy. Obtained results of quantitative coprological diagnostic tests and results for anemia assessment are criteria that provide differential diagnosis between healthy and resilient animals and easier diseases diagnostic. Since resilient animals play important role in pasture contamination, the significance of their detection is understandable.

The aim of our study was to determine the level of parasitic infections in European bison (Bison bonasus) in the Bieszczady Mountains on the basis of coprological methods: flotation, decantation and the Baermann technique. 429 faecal samples were collected from European bison in the following Forest Districts: Baligród, Komańcza, Lutowiska, Stuposiany, Lesko and Cisna. Examination of faeces revealed the presence of eggs of gastrointestinal nematodes from the Trichostrongylidae family, as well as Nematodirus sp., Aonchotheca sp. and Trichuris sp., larvae of lung nematodes Dictyocaulus viviparus, eggs of tapeworms Moniezia sp. and oocysts of 7 species of coccidia, belonging to the genus Eimeria (E. bovis, E. zuernii, E. pellita, E. bukidnonensis, E. subspherica, E. ellipsoidalis and E. brasiliensis). The population of European bison in the Bieszczady Mountains turned out to be the only free-living herd not infected with the liver fluke Fasciola hepatica. The level of parasitic infections, observed during present study, was low and did not indicate clinical signs of parasitic disease, thus it did not require deworming.

Here, economic losses caused by cattle parasites in Mexico were estimated on an annual basis. The main factors taken into consideration for this assessment included the total number of animals at risk, potential detrimental effects of parasitism on milk production or weight gain, and records of condemnation on livestock byproducts. Estimates in US dollars (US$) were based on reported yield losses in untreated animals. These estimates reflect the major effects on cattle productivity of six parasites, or parasite group. The potential economic impact (US$ millions) was: gastrointestinal nematodes US$ 445.10; coccidia (Eimeria spp.) US$ 23.78; liver fluke (Fasciola hepatica) US$ 130.91; cattle tick (Rhipicephalus microplus) US$ 573.61; horn fly (Haematobia irritans) US$ 231.67; and stable fly (Stomoxys calcitrans) US$ 6.79. Overall, the yearly economic loss due to the six major parasites of cattle in Mexico was estimated to be US$ 1.41 billion. Considering that the national cattle herd registered in 2013 included 32.40 million head, the estimated yearly loss per head was US$ 43.57. The limitations of some of the baseline studies used to develop these estimates, particularly when extrapolated from local situations to a national scale, are acknowledged. However, the general picture obtained from the present effort demonstrates the magnitude and importance of cattle parasitism in Mexico and the challenges to maximize profitability by the livestock industry without adapting sustainable and integrated parasite control strategies.
