“…In a previous study, we reported that spring-born suckler beef calves did not require anthelmintic treatment during the first grazing season (FGS) under Irish conditions [ 3 ], provided appropriate control measures were taken to prevent dictyocaulosis from occurring. These findings are in agreement with international studies where the risk of parasitic gastroenteritis (PGE) developing in spring-born suckler beef calves in the FGS is regarded as low [ 4 – 6 ]. However, PGE may develop in weaned beef calves [ 7 ] in a similar pattern to PGE in FGS dairy calves.…”

BackgroundWith concerns over the development of anthelmintic resistance in cattle nematode populations, we must re-examine our approach to nematode control in cattle. Targeted selective treatments (TST), whereby individual animals are treated instead of entire groups, are being investigated as an alternative. The study objective was to determine if anthelmintic usage could be reduced using a TST-based approach to nematode control in spring-born suckler beef cattle over their first and second grazing seasons (SGS) without affecting performance. In the first grazing season (FGS), 99 calves with an initial mean (s.d.) calf age and live weight on day 0 (June 28th 2012) of 107 (23.1) days and 160 (32.5) kg, respectively, were used. The study commenced on day 0 when calves were randomised and allocated to one of two treatments; 1), standard treatment (control) and 2), TST. Control calves were treated subcutaneously with ivermectin on days 0, 41 and 82 in the FGS. All calves were treated with ivermectin on day 124 and housed on day 133. In the SGS, only heifer calves from the FGS were used and control heifers were treated with ivermectin on day 393. Animals were weighed, blood and faecal sampled every three weeks. The TST animals were treated with ivermectin if thresholds based on a combination of plasma pepsinogen concentrations, faecal egg count and/or the presence of Dictyocaulus viviparus larvae in faeces (FGS only) were reached.ResultsNo TST calves reached the treatment threshold criteria in the FGS. The FGS average daily live weight gain (ADG ± s.e.m.) for control and TST group calves was 0.89 ± 0.02 kg and 0.94 ± 0.02 kg day−1, respectively (P = 0.17). In the SGS, all heifers were treated with ivermectin on day 431 due to clinical signs of respiratory disease. The ADG for control and TST heifers from turnout on day 321 to day 431 was 0.90 ± 0.04 and 0.80 ± 0.04 kg day−1, respectively (P = 0.03).ConclusionsSpring-born FGS suckler beef calves require minimal anthelmintic treatment to maintain performance. In contrast, clinical parasitic disease may develop in the SGS unless appropriate anthelmintic treatment is provided.

“…In the study reported here, gastrointestinal strongyle infections were detected at an expected level despite the prophylactic regimes followed by the farms. Similar to a recent Belgian study (Agneessens et al, 1997), the low intensities of infection observed in the present study did not suggest a high risk for clinical disease.…”

“…Several investigators studied the prevalence of gastrointestinal nematodes in cow-calf systems under very different geographical and climatic conditions (Ranjan et al, 1992;Hertzberg et al, 1995;Couvillion et al, 1996;Busato et al, 1997;Agneessens et al, 1997). Although diarrhoea was the most frequently diagnosed symptom in Swiss cow-calf farms, helminths were only found in 8 % of diarrhoeic calves .…”

“…Although diarrhoea was the most frequently diagnosed symptom in Swiss cow-calf farms, helminths were only found in 8 % of diarrhoeic calves . From a study conducted with cowcalf pairs in Belgium, it was concluded that it was unlikely that the observed pasture contamination with gastrointestinal nematodes was dangerous to the calves (Agneessens et al, 1997). However, the potential impact on fertility was not analysed.…”

Infections with gastrointestinal parasites (Eimeria spp., Cryptosporidium spp., Buxtonella sulcata, Fasciola hepatica, Moniezia spp. and trichostrongyles) and lungworms were monitored in five cow-calf herds in the north German lowlands. Estimated prevalences of infections with Eimeria spp. (predominantly Eimeria bovis) ranged between approximately 2 and 48%. The highest prevalences were found during late summer and autumn. On one farm Cryptosporidium spp. were detected in July and August (prevalence: 8.5 +/- 2.7% and 6.7 < 2.0%). The latter finding coincided with diarrhoea in many calves. Buxtonella sulcata was found during the entire study period in highly variable estimated prevalences ranging between zero and 73%, but without any obvious association with clinical disease. Fasciola hepatica was detected on four out of five farms at estimated prevalences of approximately 1-20%. Lungworm infections played a minor role in at least three of five study herds. The estimated prevalence of trichostrongyle infections rose from August until November whereas the intensity of infection did not change significantly. No difference in the intensity of infection could be detected between one farm on which infections with gastrointestinal nematodes were controlled only by moving the animals to an uninfected pasture in July, and three other herds on which strategic anthelmintic control was in place.

“…However, Durrie (1961) and Michel (1976) have given proper reasons that should be taken into account to tackle grassland associated parasitic diseases of livestock in Bangladesh. Agneessens et al (1997) (Haq and Shaikh, 1968;Rahman and Mondal, 1983). the absence of trematode parasites in the gastrointestinal tracts of the animals indicate that the high grasslands might be incapable of transmitting trematode infections in livestock even grazing in the rainy months of the year.…”

Examination of gastrointestinal helminth in livestock grazing in grassland of Bangladesh

To determine association of grassland with parasitic diseases of livestock in Bangladesh, the 'Tracer' animals (two cow calves and two goats) were released for a month in a grassland used for communal grazing of livestock near school premise in Kanthal, Trishal, Mymensingh, Bangladesh. After slaughtering of the tracer animals, their gastrointestinal tract examination revealed six species of nematode and one cestode. The nematode species were Haemonchus contortus, Trichostrongylus axei, Mecistocirrus digitatus, Oesophagostomum spp., Trichuris spp. and Bunostomum sp. The cestode was one of the genus Moniezia. With this preliminary study, grasslands are thought to be one of the main sources of gastrointestinal parasitic diseases of livestock in Bangladesh.
