“…oocysts' shedding. Difficult calving causes stress for the newborn calf, which decreases resistance to pathogens due to a combination of reduced calf vigor and delayed ingestion of colostrum (LORINO et al, 2005); it has been also found associated to increased mortality and morbidity in calves (LOMBARD et al, 2007). Therefore calving difficulties should not be disregarded as a risk factor.…”

“…Management factors affecting the risk of cryptosporidiosis have been identified in calves, for example, method and frequency of cleaning, type of flooring, stocking rate, and length of calving season (CASTRO-HERMIDA et al, 2002;LORINO et al, 2005;HAMNES et al, 2006;TROTZ-WILLIAMS et al, 2008). Giardia prevalence varies in cattle, and is reflected by differences in management, climate and study design (OLSON et al, 2004).…”

The objectives of this study were to estimate calf and herd prevalence of Cryptosporidium spp. and Giardia spp., the herd prevalence clustering, spatial distribution according to soil type and shedding patterns in dairy calves from Cordoba, Argentina. Six hundred twenty calves younger than 7 weeks of age from 43 dairy herds were sampled. Samples were processed with the formol-ether and modified Ziehl-Neelsen techniques. Univariate analysis and Kruskall-Wallis tests were used. Factors associated were subjected to multivariate analysis with calf shedding intensity as the response variable. Clustering of herd prevalence was assessed by a scan method, and spatial analysis was applied to explore the overlapping of high prevalence herds and soil type. Overall calf prevalence for Cryptosporidium spp. oocysts and Giardia spp. cysts were 19.35% (95% CI: 16.14; 22.54) and 34.50% (95% CI: 30.69; 38.34), respectively. Calves younger than two weeks of age were almost four times more likely to be infected with Cryptosporidium, in comparison to older ones (RR: 3.78, 95% CI: 2.27; 6.26). Giardia spp. shedding showed a similar age pattern (RR: 1.33, 95% CI: 1.02; 1.75). A primary cluster of high Cryptosporidium prevalence was found, and high prevalence herds were located in areas with poor drained soil.

“…Feeding management, (i.e., nurse [39], milk substitute feeding [41,42], early use of silage in calves' diet [41]) or any other factor interfering in the passive transfer [41] are critical for the outbreak of diarrhea.…”

Morbidity-mortality and performance evaluation of Brahman calves from in vitro embryo production

et al. 2011

BackgroundThe use of bovine in vitro embryo production (IVP) increases the reproductive potential of genetically superior cows, enabling a larger scale of embryo production when compared with other biotechnologies. However, deleterious effects such as abnormal fetal growth, longer gestation period, increased birth weight, abortion, preterm birth and higher rates of neonatal mortality have been attributed to IVP. The aim of this study was to compare the influence of in vitro embryo production and artificial insemination (AI) on gestation length, complications with birth, birth weight, method of feeding colostrum, passive transfer of immunity, morbidity-mortality, and performance in Brahman calves.ResultsWhilst gestation length and birth weight were significantly increased in IVP-derived calves, no difference in weaning weight was observed between groups. The passive transfer of immunity (PT), was assessed in IVP (n = 80) and AI (n = 20) groups 24 hours after birth by determination of gamma-glutamyl transferase (GGT) and gammaglobulin activity as well as by quantification of the concentration of total protein in serum. No differences in passive transfer or incidences of dystocia and diseases at weaning were observed between groups. Birth weight, method of feeding colostrum and dystocia were not correlated with PT in either group.ConclusionsIn this study, in vitro embryo production did not affect the health status, development, or passive transfer of immunity in Brahman calves.

“…This practice of infrequent cleaning and disinfection of calving pens on some farms is a likely contributory factor to neonatal disease in these herds [12]. The extended periods of calf residency in calving pens on some farms is an additional concern.…”

“…Studies performed internationally on suckler beef herds have tended to focus on particular areas of interest, namely, calf health [7-12] or on individual disease conditions [13,14]. Due to differences in production and rearing systems from those practiced in Ireland, predominantly grass-based, adoption of findings from international studies is not always possible or appropriate.…”

Herd health status and management practices on 16 Irish suckler beef farms

et al. 2013

BackgroundThere have been few studies published internationally which document herd health management practices in suckler beef herds and no published Irish studies. The study objective was to document herd health status and management practices on sixteen Irish suckler beef herds over a two year period (2009–2010). The farms used in the study were part of the Teagasc BETTER farm beef programme. The mean (s.d.) herd size, stocking rate and farm size was 68 cows (27.6), 2.0 LU/ha (0.3) and 64.3 (21.6) adjusted hectares, respectively. Two questionnaires were designed; 1) a farmer questionnaire to collect information on farm background and current herd health control practices and 2) a veterinary questionnaire to collect information on the extent of animal health advice given by veterinarians to their clients and identification of any on-farm herd health issues.ResultsDystocia, calf pneumonia, and calf diarrhoea, in that order, were identified as the primary herd health issues in these Irish suckler beef herds. In addition, substantial deficiencies in biosecurity practices were also identified on these farms.ConclusionsThe findings of this study may serve as the focus for future research in animal health management practices in Irish suckler beef herds.
