“…The low incidence of enzootic pneumonia in this study is in line with other studies, which suggest low levels of pneumonia in very young calves (Svensson et al 2006;Waldner et al 2010), but a higher prevalence in older calves reared on-farm as dairy replacements (Sivula et al 1996;Svensson et al 2006;Gulliksen et al 2009) or for beef production (Waldner et al 2010), or in white veal systems (Sargeant et al 1994;Bähler et al 2012;Pardon et al 2012a). …”

“…Other studies have generally not noted omphalitis as a significant cause of calf mortality, but 10-15% of calf deaths have been attributed to septicaemia (Virtala et al 1996;Bähler et al 2012) or idiopathic peritonitis (Pardon et al 2012a) and it is possible that these infections originated in the umbilicus. Antibiotic usage is common in calf rearing or white veal systems (Sargeant et al 1994;Pardon et al 2012b;Walker et al 2012), but not in bobby veal systems and this most likely accounts for the marked difference in omphalitis-related mortality.…”

“…Additionally, death was most likely within the first week of life, and gastro-intestinal disease was more prevalent as a cause of mortality at that age (Virtala et al 1996;Svensson et al 2006;Gulliksen et al 2009). Similarly, in white veal production systems, where calves were typically 1-2 weeks of age at arrival, mortality was highest in the first 2 weeks and was most commonly caused by gastro-intestinal or pulmonary diseases (Sargeant et al 1994;Bähler et al 2012;Pardon et al 2012a).…”

Digestive tract disorders, omphalitis and septicaemia were the most common reasons for pre-slaughter mortality and post-mortem wastage. Further investigation of pre-transportation husbandry and feeding practices is indicated to determine compliance with animal welfare codes by farmers that supplied calves that had no curd in the abomasum, or were immature or emaciated on arrival at the slaughter premises.

“…Further, a moderate overdispersion is consistent with the intra-herd mortality clustering as detected via the widened confidence intervals in the gee-Poisson model. Mortality clustering has been described in calf and dairy cattle holdings (Moore et al, 2002;Bähler et al, 2012;Shahid, 2013). This corresponds to the view that mortality levels in holdings are multifactorial and often management-dependent (Welfare Quality, 2009;de Vries et al, 2011de Vries et al, , 2013.…”

“…Infectious diseases are often considered as the principal cause of calf mortality, specially gastro-intestinal disorders (Svensson and Liberg, 2006;Torsein et al, 2011;Bähler et al, 2012;Daros et al, 2014) and respiratory problems (Gulliksen et al, 2009). Moreover, farms with high calf mortality are regarded as of having poor welfare at the farm level (Ortiz-Pelaez et al, 2008;Kelly, 2013).…”

IntroductIon Livestock is an inherent element of the compound farming system in Bangladesh as it besides a source of meat and milk protein, a prime source of farm power services as well as employment. The livestock sub-sector dispenses 20% and 50% of the total population a full time employment and part-time employment, respectively. The contribution of the livestock sector to total gross domestic product persisted steady within a range of 2.1-3.6% over the 1973-2008 periods. Despite a steady contribution to the Gross Domestic Product (GDP), budget allocation for this sector remained <1% of the total expenditure. Moreover, it was revealed that the growth in individual livestock products were mainly in minor products (e.g., tails, bones, etc.) and hides and skins (a major export item) rather than in milk and milk products, meat and eggs might not be very motivating because such tendency will lead to less imresearch Article Abstract | A survey was conducted to characterize calf management and hygiene practices adopted by dairy farmers at Chittagong, in Bangladesh. A total of 210 dairy farms located in 3 geographically distinct regions in Chittagong division, namely coastal, hilly and plain area, were surveyed. Calf management and hygiene practice related data was collected through a standard questionnaire and all sampled farms were visited once by technical persons and administered the questionnaire by 'face to face' method during the period July, 2015 to May, 2016. Statistically significant variations were observed in distribution of different factors through different strata (herd size and region). Among larger farms (>50 cows), 10% had a poor hygiene score whereas 32% of the smaller farms (5-20 cows) belonged to this category. 97% of the large farms used tube well water as the source of drinking water for their calves; whereas 35% of the small farms used surface water. None of the large and medium farm owner said they never clean the calf pen; 47% small farm owners said yes to it. More than half of the smallholders (54%) were discovered with raising other domestic animals and birds within the same premises. Hygiene score and surrounding environment of the farms did not show any regional variation (p>0.05). Remarkably 65% farms of the hilly area used surface water for their calves to drink with. The relationship between management practices and calf mortality/morbidity is complex. Our study design did not allow us to draw conclusions about the management and hygiene practice responsible for calf mortality/morbidity, but knowing the management practices adopted on farms is valuable for bringing attention to herds with less optimal practices and for planning meaningful experiments to explore causal affects.
